Description

Actuator for providing a lighting profile

DESCRIPTION

The invention relates to an actuator for providing a lighting profile.

The circadian rhythm (sleep-wake rhythm) of humans and other living beings is causally influenced by the concentration of the hormone melatonin in the blood and controls how awake or how sleepy a person is. The hormone melatonin is formed in the pineal gland (epiphysis). The release of the hormone through the eyes is inhibited by the presence of light above a certain irradiance and duration. The organism is awake when the melatonin level is low. The sensor for the stimulation of the chronobiological system are special cells in the retina of the eye, the so-called ganglion cells. By deliberately, specifically illuminating the ganglion cells, for example in the form of light, the melatonin level and thus the circadian rhythm of a person can be changed as desired. Since the ganglia cells, which act as receptors for stimulating the pineal gland, are "loosely" distributed only in the entire lower half-space of the retina, it is necessary to emit the light over the largest possible area from above towards the eye - so, that every cell "sees" part of the illuminated area. This is the only way this chronobiological receptor system works efficiently.

Applications for light irradiation can e.g. with jet lag problems as a result of travel, but also with insomnia, winter depression, shift work and many other areas of application. Actuators in the form of glasses with a plurality of incorporated LED light sources are often used for mobile applications.

[0004] In the case of different conventional glasses or actuators for chronobiological stimulation, the functional principle is such that LEDs are used as the light source or elements effective for lighting. are seen. In addition to effectiveness, the topic of eye safety can also play a special role when using LEDs for light irradiation.

The object of the present invention is to improve an actuator for providing a lighting profile. The actuator takes this task into account in accordance with the independent claim.

[0006] Exemplary embodiments relate to an actuator for providing an illumination profile. For this purpose, the actuator comprises at least one lighting-effective element that is designed to provide a lighting curve. Furthermore, the actuator comprises at least one coupling structure, which is at least partially arranged in a correct use position in a visual field of a user of the actuator. The lighting-effective element is designed and arranged to couple at least one light beam into the coupling structure. The coupling structure is designed and arranged in order to couple the light beam from the coupling structure in the direction of an eye of a user who carries the actuator in a correct use position.

In some embodiments, in particular in that the illuminating element couples the light beam into the coupling structure lying in a field of view of the user, it is possible for sufficient light to arrive in a user's eye for a desired effect. High peak luminance levels, as can occur, for example, in the case of direct lighting by means of a singular LED or the like, can at least be reduced and / or even avoided entirely.

[0008] An actuator can be, for example, any device or device that is designed to provide a lighting profile for a user. An actuator can be, for example, a unit or device that has at least one lighting-effective element. The illumination curve that can be generated by the at least one illumination-effective element or an exposure that can be generated can, for example, be the sole purpose of the Actuator or one of several purposes. In some embodiments, the actuator is designed to be worn on a head of a user, for example in the form of glasses, a monocle, a helmet, a protective shield, a visor, as a device that can be attached to glasses and / or the like. In other exemplary embodiments, the actuator can also be designed to be arranged in a visual field of a user but at a distance from the user's head. In these cases, the actuator can be arranged, for example, on a table, at a workplace or at another location where the user is located, for example in the form of a sign, a partition, an intermediate wall or the like.

A lighting-effective element can be, for example, any device that is designed to provide at least a portion of a lighting curve, for example a light source, in particular a conventional light source, such as a halogen lamp, low-pressure discharge lamp, incandescent lamp or UV or Infrared heater. However, it is also possible to provide light-emitting diodes such as LEDs, possibly in different colors, for example RGBW, OLED, SSL, laser diodes and / or further controllable light-emitting elements. Light emitting can also be understood to mean, for example, radiation emission in the non-visible area. In this context, effective lighting can mean that the effect of the lighting and in particular the emitted radiation is in the invisible range, for example in the infrared or in the near ultraviolet.

In a lighting run provided by the actuator, it can be, for example, any lighting course to which a user is exposed or can be exposed. Providing a light and / or a current lighting situation can also be represented and / or described with an illumination course. In some embodiments, the lighting curve can prove to be important for physiological processes in the user. In this way, stress-related reactions can be reduced or avoided, phases of rest or increased attention initiated and / or maintained and, for example, the effects of jet lag can be reduced by supplying a suitable lighting exposure over a predetermined period of time. Disease courses, for example a migraine or a depression, can also be avoided or the effects reduced by providing the lighting course in a user-specific manner. The use of light in the context of lighting to influence physiological processes can be referred to as "Human Centric Lighting" (HCL), for example. For example, the actuator can be designed to be used for HCL. The lighting curve can be characterized, for example, by a wavelength, a pulse, an intensity and / or a combination and / or a sequence of these values. Of course, a lighting course can also be constant over time.

[00011] The course of lighting can be provided, for example, by exactly one lighting-effective element or also by a plurality of lighting-effective elements. The actuator can have, for example, exactly one lighting-effective element. In exemplary embodiments of actuators which comprise a plurality of lighting-effective elements, lighting-effective elements with the same or different optical properties can be used. An optical property of an illumination-effective element can be and / or include, for example, a wavelength, an intensity, a pulse, a light distribution and / or the like. The optical property of an illuminating element can, for example, describe a characteristic of the light that is generated by the illuminating element. The lighting curve can be characterized, for example, by a radiation provided by the at least one lighting-effective element or describe it. Alternatively, the lighting curve can also be described or characterized by the light exposure the user of the actuator experiences. A light exposure experienced by the user of the actuator can differ, for example, from the radiation emitted by the at least one lighting-effective element due to reflection, scattering and / or the like. A coupling structure can be, for example, any structure that is designed and arranged to couple the light beam from the coupling structure in the direction of an eye of a user who carries and / or uses the actuator in a correct use position. For this purpose, the coupling structure can be designed, for example, to guide the light beam at least in sections. The coupling structure can comprise, for example, glass and / or a plastic, for example a transparent plastic.

With a correct use position of the actuator, it can be, for example, a position of the actuator on the user provided by a manufacturer and / or a position of the actuator on the user in which the user provides the lighting curve provided by the actuator with a desired intensity and / or effect. In embodiments in which the actuator is designed as glasses, the correct position of use can be present, for example, when the glasses are at least resting on a user's nose. In addition, the glasses can have brackets with which the glasses rest on the ears of a user. Additionally or alternatively, the glasses can also be attached to a head of the user with a rubber band. A correct use position can also be, for example, a position of the actuator on the user, in which the user wears the actuator on his head, and the coupling structure is arranged in a field of view of the user. In other exemplary embodiments, in which the actuator is designed to be arranged in a visual field of a user, but at a distance from the head of the user, for example in the form of a sign, a partition, an intermediate wall or the like, the correct use position can then be used, for example are present when the user is at a work position at a table, at a work station or at another location where the actuator is arranged. If directions are referred to below, the correct position of use is always assumed, unless stated otherwise. A visual field can be, for example, a visual field of the user's eyes at their natural, anatomical location, possibly weighted with a light sensitivity of a central nervous system that receives the light pulses and evaluates them. The visual field can, for example, describe a space that is visible to an unmoving eye, possibly in a 2-dimensional sense and / or an entirety of the optical-sensory stimuli that are guided and perceived to the user's cerebral cortex. For example, a distinction can be made between a monocular visual field, which describes the right and left eye alone, and a binocular visual field, which describes the sum of the two monocular visual fields. To describe the invention, the term "visual field" means the binocular visual field, unless expressly stated otherwise. The visual field can represent an entire area in which visual perception is possible, for example without the aid of eye movements. With a coupling structure , which is arranged in a correct position of use in a visual field, can be, for example, a spectacle lens, a protective shield for the eyes, a visor or the like a direction, a structure or an extension that is arranged essentially parallel to a direction of view of the user or another direction, structure or extension can be parallel to it u be arranged or, for example, around an angular range of up to 0.5 °, 1 °, 2 °, 3 °, 4 °, 5 °, 6 °, 7 °, 8 °, 9 ° or 10 ° of parallelism differ. Light windows, diffuser plates, Reflexionsbe rich or the like, which are arranged for example in a frame of glasses or a frame and / or are positioned differently than a spectacle lens, can then not be considered as a coupling structure in the context of this invention.

[00015] Coupling a light beam into the coupling structure can be understood, for example, to mean that the light beam uses the coupling structure at least in sections as a spreading medium, is reflected and / or scattered thereon. In addition, the light beam can be guided at least in sections in or on the coupling structure. In some embodiments, the coupling may be a direct coupling. A direct coupling can be understood, for example, to mean that the light beam, until it is coupled out of the coupling structure, only propagates within the coupling structure and / or a light guide of the actuator. In other words, the light beam of the illuminating element does not spread in air before it is coupled into the coupling structure and / or at least does not spread over a distance in air which is greater than 0.1 mm, 0.2 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm or 1 mm. A direct coupling can be achieved, for example, by the illuminating element introducing the light beam directly into an optical system, for example a light guide, a collimator, a lens or the like, or the coupling structure and for this purpose with the light guide, the optics and / or the coupling structure in an adjacent contact.

Decoupling at least one light beam from the coupling structure can be understood, for example, to mean that the light beam leaves the coupling structure as a propagation medium, is scattered and / or reflected thereon. The light beam coupled out of the coupling structure can differ from the light beam coupled into the coupling structure under certain circumstances in its optical properties such as wavelength, phase, frequency, intensity and / or the like, for example by optical effects such as reflection, scattering, refraction , Absorption and / or the like. A light beam, which is coupled out of the coupling structure in the direction of an eye of a user, can be coupled out, for example, on an inside, that is to say a side of the coupling structure facing the eye of the user. The decoupling can then take place, for example, such that the light beam at least partially strikes a retina of the user. In further exemplary embodiments, the coupling structure is mechanically connected to the actuator or a component or a structure of the actuator. The connection can, for example, be designed to be non-disruptively detachable or also releasable and / or replaceable. In embodiments in which a releasable connection is possible, the coupling structure can be removed from the actuator, for example for cleaning purposes. In the case of exemplary embodiments in which the actuator has relatively sensitive, possibly electronic components in areas outside the coupling structure, cleaning of the coupling structure can be facilitated under certain circumstances.

Additionally or alternatively, the coupling structure can have a reflection area which is designed to at least partially reflect the at least one light beam and / or to scatter it. The reflection area can be arranged, for example, in an inner area of the coupling structure. In some exemplary embodiments, this can make it possible for the reflection region to be relatively large and for light beams to be able to be coupled out uniformly over a relatively large area. This can be made possible, for example, because the light beam is not or not only reflected on a lower edge of the coupling structure, as in some conventional actuators. Instead, in some embodiments, it may be possible for the light beam to be coupled out on a largest surface of the coupling structure and / or a surface that faces the eye of the user. A largest area of the coupling-in structure can be, for example, an area that the user's line of sight can meet as normal to the surface or runs essentially parallel to it. The largest side surface can, for example, describe a side of the coupling structure that has a larger area than all of the side surfaces of the coupling structure. This side surface of the coupling structure can have a concave or a convex curvature, for example. The coupling structure can, for example, have two largest side faces, which are opposite one another in the viewing direction of the user when the user is looking straight out in a correct use position of the actuator. An area, for example a Reflection area, which is arranged in an inner area of the coupling structure, can be arranged, for example, at a distance from an edge and / or a side surface with a small extension of the coupling structure. A side surface with a small extension of the coupling structure can, for example, be arranged parallel to a viewing direction or with the possible deviations from it already mentioned, or limit the coupling structure parallel to a viewing direction. The small side surfaces of the coupling structure can be, for example, an area which is in contact with a frame, for example an eyeglass frame, if it is an eyeglass model with a fully or partially running frame. In addition or as an alternative, the reflection region can also be designed, for example, in order to bring about an internal incomplete reflection between the front and back of an eyeglass lens.

The reflection area can be formed in different ways in order to achieve the desired reflection behavior. In some exemplary embodiments, the reflection area comprises, for example, a microstructure or a plurality of microstructures which is arranged or designed in such a way that the light is coupled out as homogeneously as possible over the surface of the reflection area or also with a specific brightness curve in one direction of the user. For this purpose, the microstructure can have, for example, a plurality of particles, pores or the like, which are designed and arranged in order to couple the light beam out of the coupling structure. The microstructures can, for example, all be arranged in a layer which comprises the thickness of a diameter of a microstructure in the viewing direction. Two directly adjacent microstructures can be spaced apart, for example, by at least a single, triple or 10 times the value of their diameter. For example, no further microstructures can be arranged between two directly adjacent elements, for example two directly adjacent microstructures. In some embodiments, it can be achieved, for example, that the reflection area appears transparent in an unilluminated state. The microstructure, which can also be referred to as a scattering particle, can comprise, for example, another material and / or which consist of this, as a base material of the coupling structure, for example another plastic, glass, aluminum oxide and / or the like. The microstructure can, for example, comprise a material in which the light beam has a different propagation speed.

In some embodiments, the reflection area comprises a plurality of phosphor dots or phosphor crystals, for example as a microstructure. The majority of the phosphor dots or phosphor crystals can be arranged in a common plane and / or can be arranged in different or several planes. For this purpose, the plurality of phosphor dots or phosphor crystals can be integrated in the coupling structure, for example, that is to say they can be enclosed on two, three or four sides by the material of the coupling structure or applied to a surface of the coupling structure. The phosphor dots and / or the phosphor crystals can be designed, for example, as micro dots. In addition, the applied and / or applied phosphor micro dots and / or crystals can be excited with blue light and / or UVA light.

In addition or alternatively, the reflection region can have a step structure which is designed to couple the light beam in the direction of the eye. In some embodiments, the step structure may include a plurality of steps. Because the reflection region has a plurality of steps, it may possibly be possible for light to be coupled out of the coupling structure at each of the steps arranged at different heights of the coupling structure, which can lead to a uniform coupling.

In other embodiments, the reflection area comprises an activatable diffuser, which can be switched from transparent to diffusely reflective. To achieve this effect, the reflection area can, for example, be a coating or an intermediate Include layer that can be switched from transparent to diffusely reflective. This switchover can take place, for example, by changing a voltage, a temperature and / or a light intensity, possibly also as a function of a wavelength or a spectrum. The coating or the intermediate layer can, for example, also be designed to react to magnetism. For example, a change in a magnetic field can cause a change in a state of the reflection region from transparent to diffuse reflective.

In some further exemplary embodiments, the reflection region has structures that are engraved and / or formed by recesses. These can have essentially the same arrangement and / or properties as the microstructures. The engraved and / or light-scattering structures formed by recesses can then be arranged, for example, in the interior of the reflection region. In some exemplary embodiments, this can make it possible, for example, for the reflection region to have smooth and / or easy-to-clean outer surfaces. In an alternative embodiment, the engraved and / or structures formed by recesses can also lie on a surface of the reflection area. For example, a laser or another tool can be used to engrave the structures. The recesses can be produced, for example, by material removal or appropriately structured tools, for example injection molding tools.

[00025] In addition or alternatively, the reflection region can comprise a plurality of reflection plates. The reflection plates can be brought from a first position, in which they are arranged essentially parallel to a viewing direction, which can also be referred to as the optical axis, to a second position, in which they are arranged such that they have the at least one light beam redirect towards the user's eye. To change a position of the reflection plate, for example, an electromagnetic field, a magnetic field and / or the like can be applied and / or changed. In the first position, the reflection area can appear transparent and / or transparent. This can be done, for example achieved that the side of the reflection plate facing the user's eye in the first position is so narrow that the reflection plate is not visible to the user. The light beam redirected by the reflection plate can, for example, be emitted by an illumination-effective element which is arranged within the coupling structure. For example, each reflection plate can be assigned at least or exactly one lighting-effective element, for example in the form of a MicroLED, for example a Micro-SideLED. The reflection plate and / or the illumination-effective elements can be smaller in this embodiment, for example, smaller than a resolution of the human eye and / or arranged evenly distributed within the coupling structure.

In some further exemplary embodiments, the reflection region and / or the coupling structure comprises a partial mirroring. The coupling structure can, for example, be designed to be transparent and have a partially transparent reflection layer as the reflection region. A partially transparent reflection layer can be, for example, a layer and / or a surface configuration of a component, for example the coupling structure, which is designed to only partially reflect an incident light beam, the other portion passing through the reflection layer. The semitransparent reflection layer can, for example, be arranged on a side of the coupling structure facing the user's eye. For example, a translucent scatterer can be arranged between the light source and the reflection layer. In these exemplary embodiments, a portion of the light can then be reflected specularly or specularly. In some embodiments, the actuator can also include a combination of at least two different embodiments of reflection areas.

In order to couple the at least one light beam into the coupling structure and / or the reflection area, the at least one lighting-effective element can be arranged on the actuator in different ways. In some embodiments the lighting-effective element is viewed in the user's direction of view, arranged laterally to the coupling structure. A lighting-effective element, which is viewed in the user's direction of view, is arranged laterally to the coupling structure, for example along a direction that extends between the ears of a user and extends over a nose of the user and hereinafter as an ear-nose direction is designated to be arranged. In some exemplary embodiments, this can make it possible, for example, for the light beam to be coupled in substantially parallel to a longest dimension or an edge of the coupling structure. In other words, the at least one lighting-effective element can be arranged in order to couple the at least one light beam at a lateral outer edge of the coupling structure. For this purpose, the lighting-effective element can be arranged completely or partially outside an extension of the coupling structure, for example on a side of the coupling structure facing away from the ear-nose direction of the nose when the user is wearing the actuator in a correct use position. The illuminating element can also be arranged in the area of a side of the coupling structure facing the nose in the ear-nose direction. In the direction of view, the illuminating element can be overlapping or at least partially arranged at the same height as the coupling structure.

In addition, the actuator or the coupling structure can have a light guide which is designed to guide the light beam provided by the illuminating element into the reflection area. In some embodiments, this may make it possible to reduce the number of elements effective in lighting. This can be achieved, for example, in that the light guide, which is arranged, for example, parallel to the ear-nose direction, introduces the light emitted by the at least one lighting-effective element into the reflection region in a uniformly distributed manner. The light guide can for example be arranged along an upper edge of the coupling structure, in one embodiment along an upper edge of a spectacle lens. The light guide can, for example, have a plurality of Generate virtual light sources that are spaced from each other along the ear-nose direction. For this purpose, the light guide can have, for example, a greatest extent arranged essentially parallel to the ear-nose direction. Over the entirety of the majority of the virtual light sources, the light can then be introduced into the reflection region. The light guide can, for example similar to the reflection region, be integrated in the Einkop pel structure and be firmly connected to it and / or be integrally formed with it. In other exemplary embodiments, the light guide can also be a component different from the coupling structure. In a correct use position, the light guide can be arranged, for example, above the reflection area. Along a direction that extends from a nasal syringe to a forehead of the user and is referred to below as the nose tip-forehead direction, the light guide can have, for example, a smaller extent than the reflection area, for example the reflection area can be up to 1.5, 2 , 2.5, 3 times larger than the light guide.

In embodiments in which the actuator has more than one coupling structure, each coupling structure can have its own light guide. The light guides of two coupling structures of an actuator, each associated with an eye of a user, can be optically separated, for example, so that the light guide of the first coupling structure cannot couple light into the light guide of the second coupling structure. Alternatively, two coupling structures can also have a common light guide that is designed to guide light into the reflection region of the first and second coupling structures. The illuminating element can be arranged in the ear-nose direction, for example, overlapping the light guide or at the height of the light guide.

In embodiments in which the actuator is a pair of glasses, the coupling structure can include the lens or be designed as this. In embodiments in which the actuator is designed as a helmet or protective shield and / or in one of these Components are integrated, the coupling structure can be arranged in the protective shield and / or the visor and / or be formed as this. The coupling structure can, for example, have a smaller or the same dimension in the direction of the user when the actuator is worn in a correct position of use, which also has the spectacle lens, the protective shield and / or the visor in which it is arranged. The coupling structure can, for example, have a smallest dimension, which is arranged essentially parallel to a viewing direction of the user of the actuator in a correct use position.

In some embodiments, the actuator and / or the coupling structure can be connected to glasses, for example optical glasses or sunglasses, in a manner similar to a removable tinted sunglasses lens. For this purpose, the actuator can have, for example, a connection device which is designed to establish a connection with glasses, in particular a non-destructively releasable connection. For example, force-fitting, form-fitting and / or material-locking connecting elements can serve as the connecting device, for example clamping, clip, snap-in connections and / or the like.

In embodiments in which the actuator is a pair of glasses, at least one spectacle lens can be provided at a distance from the at least one coupling structure. The coupling structure can be closer to the user than the spectacle lens in the viewing direction of a user when the actuator is worn in a correct use position. In embodiments in which the actuator is designed as a helmet or protective shield and / or is integrated therein, the coupling structure can be arranged within the protective shield and / or the visor in the viewing direction of the user. In some exemplary embodiments, the coupling structure can be arranged essentially parallel to an eyeglass lens and / or protective shield and / or visor. Additionally or alternatively, the coupling structure can have a similar curvature as the spectacle lens and / or the protective shield and / or the visor. The coupling structure can in some embodiments, for example in the direction of view of the user, if the actuator is worn in a correct use position, have a smaller dimension than the spectacle lens, the protective shield and / or the visor, spaced apart from which it is arranged. The coupling structure can, for example, be arranged in the direction of the user in an area in front of the spectacle lens and / or the protective shield and / or the visor, which does not shade the user's field of vision in a correct use position of the actuator. A viewing area through the spectacle lens and / or the protective shield and / or the visor is thus available to a user when the position of use is correct. In some embodiments, the coupling structure can be arranged above a see-through area. For example, the coupling structure can be arranged in the manner of a backdrop, spaced apart from the spectacle lens and / or the protective shield and / or the visor. For example, in some exemplary embodiments the spectacle lens and / or the protective shield and / or the visor can be changed independently of the coupling structure.

In embodiments in which a coupling structure is provided at a distance from the at least one spectacle lens and / or a protective shield and / or a visor, a mirroring of the at least one spectacle lens and / or the protective shield and / or that of the visor can be provided at least in an area may be provided which is in front of the coupling structure in the direction of view of a user who carries the actuator in the correct position of use, for example in a tip-forehead direction. The mirrored area can, for example, be essentially parallel to the coupling structure. For example, the coupling structure can essentially not be visible or hidden to an observer of the user. For example, this can be a partial mirroring of the spectacle lens and / or the protective shield and / or the visor. Completely or alternatively, complete mirroring of the spectacle lens and / or the protective shield and / or the visor can also be provided. Additionally or alternatively, mirroring on a side of the spectacle lens and / or the protective shield facing the coupling structure can also be the and / or the visor. A disruption to potential viewers of the user by stray light from the coupling structure can thus be avoided. In addition, scattered light can be reflected back in the direction of view of a user.

In some embodiments, the coupling structure and the lighting-effective element are arranged, so that when the glasses are folded, the lighting-effective element, for example in the form of the LED, or the LED window comes to lie exactly on the outer edge of the coupling structure and through one clear, possibly polished edge surface can couple light into the coupling structure. In addition or as an alternative, the lighting-effective element can be arranged in and / or on a bracket of the glasses and / or the actuator. In some exemplary embodiments, an improved actuator can thereby be provided. On the one hand, this can be made possible, for example, by eliminating the need for contacting via a hinge with which the bracket is attached to a frame of the glasses. Furthermore, cleaning of the actuator can be facilitated, for example, by separating the bracket with the illuminating element from the coupling structure. In some embodiments, electronic and / or sensitive components can then be arranged on the removable bracket of the actuator. In addition or as an alternative, the element or elements which are effective in lighting can be arranged in the region of a starting point of the bracket.

Additionally or alternatively, the illuminating element can be designed and arranged in order to couple the at least one light beam into the coupling structure from above in a correct use position. In some exemplary embodiments it can be achieved that the light guide can be omitted. Under certain circumstances, a greater number of lighting-effective elements can also be arranged in these exemplary embodiments. The lighting-effective element can be arranged, for example, in the correct viewing position of the user in an overlapping position, that is, for example at the same height, to the coupling structure in order to introduce the light evenly into the coupling structure. In embodiments in which the actuator is designed as glasses, the lighting-effective elements can be arranged, for example, in or on a frame of the glasses. A frame of a pair of glasses can be understood to mean, for example, a structure of the glasses that accommodates the lenses or at least one lens. In exemplary embodiments in which the actuator is designed as glasses, the at least one lighting-effective element can be arranged, for example, in the region of the nose bridge of the glasses. At least two or more lighting-effective elements can also be provided in the area of the nose bridge, each of which can be coupled in essentially opposite directions in parallel along the ear-nose direction into a coupling structure.

In addition or alternatively, the lighting-effective element can be arranged inside or on the coupling structure. In some exemplary embodiments, this can make it possible, for example, for a light guide and / or a reflection region to be eliminated. The illuminating element can then couple at least one light beam directly into the coupling structure and / or be formed in order to emit diffuse lighting. The lighting-effective element can then be designed, for example, as an OLED. Additionally or alternatively, the lighting-effective element can also be designed as a micro-LED or micro-side LED. An element, for example the lighting-effective element, which is arranged on the coupling structure, can be applied, for example, to the coupling structure, for example on a side facing the user and / or on a side facing away from the user, for example a largest side surface which have in the viewing direction of a surface normal. An element which is arranged within the coupling structure can, for example, be covered by a material of the coupling structure in the viewing direction. A lighting-effective element, which is arranged inside or on the coupling structure, can for example be spaced apart from a frame of the glasses and / or all small areas of the coupling structure.

[00037] In some further exemplary embodiments, the coupling structure is formed, at least in some areas, by at least to appear transparent in an operating state. In some exemplary embodiments, this can possibly make it possible for the coupling structure to function as spectacle lens, for example correction glass, sun protection, protective glass and / or at least in one operating state, for example in an operating state in which no light beam from the illuminating element is coupled into the coupling structure. or the like can take over. Under certain circumstances, the actuator can then also serve as reading glasses, correction glasses, sunglasses, protective glasses and / or the like, depending on the type of glasses used as the coupling structure. For this purpose, the coupling structure can comprise, for example, a transparent material which is designed to allow at least 50%, 70%, 80%, 90%, 95%, or 98% of radiation to pass through, for example in the visible region which occurs on the coupling structure to let. In addition or as an alternative, the coupling structure can be designed to reflect less than 0.5%, 1%, 2% or 5% of the incident light, for example in the visible spectrum, in at least one operating state. The area in which the coupling structure has the described transparency can, for example, overlap completely or at least partially and / or be larger than 50%, 60%, 70%, 80%, 90 with the area in which the reflection area is arranged % or 95% of the total coupling structure.

In some embodiments, the actuator has a device that is designed to supply the actuator and / or electronic components of the actuator, such as the lighting-effective elements with energy. The device can be, for example, a battery, a rechargeable memory, for example a rechargeable battery or the like. In the event that a rechargeable memory is provided, the actuator can include an infrastructure for loading the memory, such as an interface for coupling to a power network. The interface can comprise, for example, an inductive interface with an antenna, a UBS interface and / or any other interface via which the memory can be loaded. Of course, the infrastructure for loading the memory can also be a control unit Include, which is designed to monitor loading of the memory, regulate and / or control. The control unit can be designed, for example, in order to avoid damage due to overloading and / or to indicate that the minimum loading quantity is below the minimum. Of course, the actuator for energy supply can also include solar cells and / or a thermoelectric voltage supply.

[00039] In addition or alternatively, the actuator can comprise a control unit. The control unit can, for example, be designed to generate a control signal that includes information that is designed to control the at least one lighting-effective element in such a way that the lighting-effective element provides the lighting curve. In some exemplary embodiments, it can be achieved, for example, that the illumination curve is generated based on the receipt of a control signal. The control signal can be generated, for example, based on a program selection by the user.

[00040] In addition, the actuator can comprise a receiving unit and / or a sensor which is and / or is designed to receive a context-specific data record, an environment-specific data record and / or a user-specific data record. The control signal can then be generated, for example, based on the receipt of at least one data record. In some exemplary embodiments, this can make it possible, for example, for the lighting course to be adaptable to specific users, to a specific situation or to a specific environment. Conditions that the sensor or another sensor system can detect, for example, a temperature, a skin resistance, an oxygen content, a blood pressure, a pulse of the user and / or a light or radiation dose, for example UV and / or IR, which the user has already been exposed and / or the like. The control unit can comprise, for example, a communication interface, for example in the form of the receiving unit and / or independently thereof. The communication interface can include, for example, an optical connection, a radio connection and / or be wired or the like. The sensor and / or the control unit and / or the receiving unit can for example be arranged in or on a bracket of the actuator. Alternatively, the sensor can also be arranged spatially separate from the actuator. In some exemplary embodiments, the actuator can possibly be designed to provide a user-specific lighting curve. A user-specific lighting curve can be understood, for example, to provide a light exposure that is as targeted as possible and / or adapted to the needs of the user. The user can expose himself to this light exposure, it being possible for an effective portion of the light from the light exposure and / or the course of the illumination to be recorded, in particular by specific receptors in the eyes and / or the skin.

[00042] Exemplary embodiments also relate to a method for providing a user-specifically adaptable lighting profile with the following steps:

• Determination of actuators in an environmental context

• Acquisition of actuator data records of the determined actuators

• Identification of a user, in particular by means of an identification device

• Providing a user-specific data record and / or an environment-specific data record and / or a context-specific data record

• Generation of a control signal for one or more of the actuators determined by a control unit as a function of the one or more data records.

[00043] In some exemplary embodiments, the method enables a lighting course to be controlled by the user by controlling the fact that data records specific to the user or the environment or the context are included in the control. The user situation can be defined by taking one or more of these data records into account, and a combination of several of these data records can possibly represent the user situation more comprehensively. The user-specific data record can also contain information about the user history contain. Exemplary embodiments also relate to a system for carrying out the method for providing a user-specifically adaptable lighting curve. Exemplary embodiments also relate to an actuator, for example an actuator according to one of the exemplary embodiments already described, which is designed to be controlled by the method according to at least one of the exemplary embodiments.

La and lb show different representations of an actuator 10 for providing an illumination curve. In the embodiment of FIGS. La and lb, the actuator 10 is designed as glasses, with a frame 15 to which a bracket 16a and 16b is attached in each case via a bracket share 18a or 18b. Separated by a nose bridge 17, which is part of the frame 15, two spectacle lenses 12a and 12b are held on the frame 15. In a correct position of use, the nose bridge 17 lies on a bridge of the nose of a patient. user. In each of the brackets 16a and 16b, a lighting-effective element 11a and 11b is arranged, which in this embodiment is designed as an LED. The illumination-effective elements 11a and 11b are designed to provide at least a portion for an illumination course and to couple at least one light beam into the spectacle lenses 12a and 12b, which serve as a coupling-in structure.

The coupling structures 12a and 12b are essentially constructed analogously. Therefore, the structure is described below on the basis of the coupling structure 12a. In order to couple the at least one light beam provided by the illuminating element 11a or the light emitted by the illuminating element 11a out of the coupling structure 12a in the direction of an eye 4 of a user, the coupling structure 12a comprises a reflection area 13a and a light guide 14.

The reflection region 13 is arranged in an inner region of the coupling structure 13 and is spaced apart from a small side surface la, lb, lc or ld of the coupling structure 12a. The small side surfaces la to ld are the side surfaces of the coupling structure 12a, which limit the side surfaces 2a and 2b opposite in the viewing direction D of the user. The direction of view D can be, for example, a direction in which the user looks when he looks straight ahead. The greatest extent of the reflection region 13 is essentially parallel to the side surfaces 2a and 2b and is designed to lead the light beam out of the side surface 2a to a user.

The reflection region 13 comprises a plurality of microstructures 19 which are designed such that the light is coupled out over a surface of the reflection region 13 as homogeneously as possible or with a specific brightness curve on an inside of the side surface 2a. In other words, the reflection area 13 comprises a diffusely radiating or reflective coupling-out structure. The microstructures 19 can for example have a size between see 1 gm and 5gm and / or the like. Two directly adjacent microstructures, between which no further microstructure is arranged, can be at a minimum distance of 10 gm, 12 gm, 15 gm, 20gm or the like, for example. In the exemplary embodiment in FIGS. 1 a and 1 b, the microstructures 19 are arranged only in a single layer, which is spaced further apart from a side 2 a of the coupling structure 12 a facing the user than from a side 2 b of the coupling structure 12 a facing away from the user.

[00073] The material of the microstructures 19 can be any material that differs from a material, for example a base material, in which the microstructures 19 are embedded. The coupling structure 12a, for example, can comprise PMMA or another transparent thermoplastic as the base material. Of course, other conventional materials used for the manufacture of spectacle lenses can also be used as the material for the coupling structure 12a, for example glass. In a state in which the illuminating element 11a emits no light, the coupling structure 12a can appear transparent, at least in areas outside the light guide 14. For example, the coupling-in structure 12a can then serve as an optical spectacle lens in the form of a correction lens with a thickness and / or as a sunglasses lens.

The illuminating element 11a is arranged to couple at least one light beam into the small side surface 1c of the coupling structure 12a. For this purpose, the illuminating element 11a is viewed in the viewing direction D of the user, arranged laterally to the coupling structure 12a. Along a direction which extends in a correct use position of the actuator 10 between an ear and a nose of the user, which can be referred to as the ear-nose direction B, the illuminating element 11a is at an ear-nose direction B Nose of the user facing away from the side of the coupling structure 12a. The directions D, B and more are shown for reasons of clarity in Fig. 2a. The light guide 14 is arranged at the same height as the illuminating element 11a, so that the illuminating element 11a can couple at least one light beam directly into the light guide 14. Parallel to the ear-nose direction B, the light guide 14 has an extent which corresponds to a bulging extent of the reflection region 13. The light guide 14 is arranged between the frame 15 and the reflection area 13 above the reflection area 13. In addition, the light guide 14 is designed to introduce the light emitted by the illuminating element 11a along an entire extent of the reflection region 13 between the illuminating element 11a and the nose bridge 17 into the reflection region 13. For this purpose, the light guide 14 has a zigzag structure which can be seen schematically in FIG. Of course, the light guide in other, not shown Ausführungsbei play can also be designed in a different way to initiate the light of the illuminating element in the reflection region.

As can be seen in FIG. 1b, the actuator 10 comprises a control unit 9 which is designed to control at least the illuminating element 11a. In some exemplary embodiments, a further control unit can be arranged analogously in the second bracket 16b in order to control the second lighting-effective element 11b. Alternatively, the control unit 9 can also be designed to control both or all lighting-effective elements 11 of the actuator 10. The control unit 9 can be designed, for example, as a processor, printed circuit board (PCB) with an integrated circuit (IC) or as another programmed hardware component. Under certain circumstances, the control unit 9 can also have an interface that is designed to receive signals, for example from a cloud, from a sensor and / or the like.

In the embodiment of FIGS. La and lb, the lighting-effective elements 11a and 11b, each in the form of an LED with an associated driver, are seated in one of the temples 16a and 16b. The light or the radiation generated is coupled into the spectacle lens equipped with the microstructure 19 as a coupling structure 12a or 12b by coupling light from the side. Of course, in other, not shown exemplary embodiments, the actuator can also be designed as a visor, helmet, shield or the like and / or other lighting-effective elements can be implemented instead of LEDs.

2a to 2f show different schematic representations of an actuator 20 according to a further exemplary embodiment. The actuator 20 is essentially similar or structurally identical to the actuator 10, but differs by a reflection area 13a and a light guide 14a, which are described in more detail below.

As can be seen in FIG. 2c, the reflection region 13a has a step structure, which can also be referred to as a linear microstructure. The step structure is arranged on the side surface 2b of the coupling structure 12a and is designed to couple light rays 5, which are guided by the light guide 14a onto the reflection region 13a, in the direction of the eye 4 of a user. The step structure comprises three offset reflection surfaces 21a, 21b and 21c, which are offset from one another in a viewing direction D and in a direction that extends from one tip of the nose to one forehead, which can also be referred to as the tip of the nose-forehead direction C, and that from can hit the light guide 14a led light beam 5. The reflection surfaces 21a, 21b and 21c each enclose an angle a of 45 ° with respect to a surface normal 22 to the coupling structure 12a. Depending on the height of a width b of the reflection region 13a, a light beam is coupled into the coupling structure 12a, the light beam 5 then strikes one of the reflection surfaces 21a, 21b or 21c arranged along the width b.

The reflection surfaces 21a, 21b and 21c each have a height h in the nasal tip-forehead direction C or parallel thereto, which is 0.01 mm. Two directly adjacent reflection surfaces, for example the reflection surfaces 21a and 21b have in the tip of the nose Forehead direction C or parallel to it a distance a that is 0.1 mm. In the ear-nose direction B or parallel thereto, the reflection surfaces 21a, 21b and 21 have an extent which corresponds to that of the reflection region 13a and that of the coupling structure 12a in this direction. In other exemplary embodiments, the height h can be in a range of values between 0.005 and 0.03 mm and / or the distance a can be in a range of values between 0.05 and 0.3 mm. An extension of the reflection surfaces in the ear-nose direction B or parallel to it can, for example, also be smaller than an extension of the coupling structure in the same direction. Additionally or alternatively, the step structure can also comprise a different number of steps. In other embodiments, the angle a can also be in a range of values with an initial value of 35 °, 40 °, 45 °, 50 °, 55 ° and / or an end value of 40 °, 45 °, 50 °, 55 °, 60 ° lie. The steps preferably have a resolution that is smaller than a resolution of a human eye 4 and does not disturb a view of a user of the actuator 20.

2d and 2e, the light guide 14a of the actuator 20 is described in more detail. The light guide 14a has a plurality of reflection structures 23a, 23b etc. which are designed to guide a light beam onto the reflection area 13a. The reflection structures 23 each have the shape of a triangle and can be designed as a triangular breakthrough region. The reflection structures 23a, 23b etc. can be, for example, through holes and / or blind holes with a triangular cross section that run parallel to the viewing direction D.

The reflection structure 23a, which is arranged closer to the nose bridge 17 and thus further away from the illuminating element 11a than the reflection structure 23b, has a larger cross section parallel to the viewing direction D than the reflection structure 23b. This can possibly achieve that the light rays are introduced uniformly into the reflection region 13a. The reflection structures 23 have the same orientation despite cross sections of different sizes. The reflection structures 23 can be arranged parallel to the nasal syringe eye direction C at different heights. In the embodiment of Fig. 2d parallel to the ear-nose direction B, reflection structures 23 lying further inside along the nose tip-forehead direction C are arranged higher than reflection structures 23 lying further outside.

In order to guide the light or the rays of the illuminating element 11a onto the reflection structures 23 of the light guide 14a, a collimator 24 is arranged in a direction in which the at least one light beam leaves the illuminating element 11a. A collimator can, for example, be designed to generate light with an approximately parallel beam path from a divergent source, for example the illuminating element 11a. A collimation can be used, for example, to give light or the at least one light beam a specific direction.

Similar to that described for the actuator 10, the lighting-effective element 11a and all other electronic components in the temple 16a and 16b are also arranged in the actuator 20. The lighting-effective element 11a as an LED and the control unit 9 are arranged on a printed circuit board 8. The circuit board 8 of the actuator 20 also includes a battery 7 for a power supply and an interface 6. The interface 6 can, for example, be designed as a radio interface, for WiFi, Bluetooth and / or other wireless signal transmission methods. A circuit board 8a of the bracket 16b can be populated analogously. The actuator 10 can of course also comprise the printed circuit board 8 or a similar component or an interface and / or a component for an energy supply, for example a rechargeable battery.

3a and 3b show schematic representations of an actuator 30 according to a further exemplary embodiment. Actuator 30 is essentially similar or structurally identical to actuators 10 and 20, so only differences or different features are described below. The actuator 30 comprises three lighting-effective elements 11c, lld, and Ile, which are designed to couple light and / or at least one light beam into the coupling structure 12a. Illumination-effective elements are for the coupling structure 12b Arranged analogously, the arrangement for the coupling structure 12a is described below as a representative.

The lighting-effective elements 11c, lld, and Ile are arranged in the frame 15 of the actuator 30 and in such a way that light or at least one light beam is coupled into the coupling structure 12a from above in a correct use position and directed onto the reflection area 13b. Since the lighting-effective elements 11c, lld and Ile are arranged above the reflection area 13b, the light can be coupled directly into the reflection area 13b, for example without being deflected by a light guide. A light guide as in the exemplary embodiments in FIGS. 1 and 2 can be omitted, for example. The three illuminating elements 11c, lld and Ile are arranged parallel to the ear-nose direction or between the hinge 18a and the nose bridge 17 at the same height and evenly distributed. Furthermore, the three lighting-effective elements 11c, lld, and Ile are at least partially or completely overlapping to a width b, that is to say an extension, of the coupling structure 12a in the viewing direction B, so that the lighting-effective elements 11c, lld and Ile light directly into the coupling structure 12a can couple. In Fig. 3b this arrangement is due to the schematic representation, not recognizable and shown distorted.

The reflection region 13b is designed as an intermediate layer embedded in the coupling structure 12a, which can be switched over from trans parent to diffusely reflective. The intermediate layer can, for example, be arranged entirely within the coupling structure 12a. This switchover can take place, for example, via a change in an applied voltage, temperature, magnetism or light intensity, possibly also as a function of a wavelength or the spectrum provided by the lighting-effective elements 11c, lld, and Ile. In other words, the reflection area 13b can be designed as an activatable diffuser, which assumes its property as a diffuser only if at least one illuminating element 11c, lld, and / or ile light or at least one light beam is emitted. In other states of use, For example, if the actuator 30 is to be used as reading glasses, sunglasses, correction glasses, protective glasses or the like, the reflection area 13b can appear transparent and have no or less reflective properties.

In other, not shown exemplary embodiments, the reflection area can also be designed as a coating of the coupling structure. A coating can represent a surface of the coupling structure, for example. In some embodiments, not shown, the lighting-effective elements can also be arranged at different heights in the frame, in a different grouping and / or in number. Of course, reflection areas that work according to a different principle, for example as described for other exemplary embodiments, can be arranged in an actuator with the described arrangement of the illuminating elements.

As can be seen from FIGS. 3c and 3d, the activatable reflection region 13b can also be arranged in an actuator 30a, in which the or the lighting-effective elements 11a and 11b are arranged laterally, as for example already for the exemplary embodiments of the 1 and 2 are described. Then, a light guide 14a or 14b is also provided in order to guide the light into the reflection area 13b of the corresponding coupling structure 12a or 12b. In the exemplary embodiments in FIGS. 3a to 3d, the control unit 9 can be designed, for example, to to output a control signal which causes a change of a state of the reflection area 13b.

4a and 4b show schematic representations of an actuator 40 according to a further exemplary embodiment. The actuator 40 is essentially similar or structurally identical to the actuators 10, 20 and 30, therefore differences or differing features are mainly described below. As lighting-effective elements 11f, actuator 40 comprises a transparent lighting-effective element that overlaps completely within and parallel to viewing direction D. to the coupling structures 12a and 12b. The transparent illuminating element llf is designed to guide diffuse light in the direction of an eye 4 of a user. For this purpose, the illuminating element 11f couples at least one light beam into the coupling structure 12a or 12b. The light beam is then decoupled from the coupling structures 12a and 12b in the direction of an eye 4 of a user who wears the actuator 40. The illuminating element 11f is arranged in a region of the coupling structure 12a and 12b, in which the reflection region is arranged in other exemplary embodiments. A reflection area and / or a light guide can be omitted in the actuator 40.

In the actuator 40, the illuminating element 11f is designed as a transparent OLED strip (abbr. From the English: organic light emitting diode for: organic light emitting diode), which is introduced as an intermediate layer in the glasses or coupling structures 12a and 12b. Contacting for energy supply and / or actuation of the illuminating element 11f via the control unit 9 (not shown in FIGS. 4a and 4b) takes place via the frame 15 and / or one or both of the brackets 16a and 16b. When the voltage is applied, the OLED strip emits light.

The actuator 40 has exactly one illuminating element 11f, which extends over both coupling structures 12a and 12b, which have a connection under the nose bridge 17. In the case of other exemplary embodiments, which are not shown, exactly one or a plurality of lighting-effective elements can also be arranged in or on each of the coupling structures. For example, for different light colors, several elements and / or strips which emit light and emit light of different wavelengths can also be arranged in the coupling-in structure or the glasses. Of course, in other exemplary embodiments, the element or elements which are effective for illumination can also be arranged on a surface of the coupling structures 12a and / or 12b, for example on one of their largest side surfaces 2a or 2b. 5a to 5f show schematic representations of an actuator 50 according to a further exemplary embodiment. Actuator 50 is essentially similar or structurally identical to actuators 10, 20, 30 and 40, which is why differences or differing features are mainly described below. As lighting-effective elements 11g, 11h etc., the actuator 50 comprises a plurality of micro LEDs, for example micro-side LEDs. The term “microLEDs” is understood to mean, for example, microscopic light-emitting diodes which can be arranged in regular patterns, for example rows and columns. These can be, for example, in the line of sight between two transparent disks 51a and 51b of the coupling structure 12a, which are arranged opposite in line of sight D. PMMA glasses must be embedded.

As can be seen in the enlarged section of FIG. 5f, the illuminating elements 11g, 11h, IIIi, IIj are arranged in rows and columns. In other exemplary embodiments, the lighting-effective elements 11g, 11h, IIIi, 11j can also have a different arrangement. The lighting-effective elements 11g, 11h, IIIi, 11j have a size that is smaller than a resolution of the human eye 4 at a distance from the coupling structure 12a in a correct use position of the actuator 50.

The lighting-effective elements 11g, llh, lli, llj etc. are contacted via conductor tracks 54a and 54b that are vapor-deposited on an inside of the panes 51a and 51b. The conductor track 54a can comprise, for example, a plus pole (conductor path +) and the conductor track 54b a minus pole (conductor path -). In other exemplary embodiments, this arrangement can also be interchanged, for example. The lighting-effective elements 11g, 11h, IIIi, IIj etc. are arranged in such a way that they emit light in a direction between the hinge 18a and the nose bridge 17 or parallel to the ear-nose direction B, as indicated by an arrow 53 in FIG 5c indicated.

To the light emitted from the illuminating elements 11g, 11h, lli, llj, etc. toward an eye 4 of a user conduct or couple out of the coupling structure 12a, a plurality of reflection plates 52 are provided. Each of the reflection plates 52 is arranged in a beam path of an illuminating element 11g. Representative, the reflection plate 52a is described in more detail with reference to FIGS. 5c, 5d and 5e. As can be seen in the enlarged view of FIGS. 5e and 5d, the reflection plate 52a comprises three partial regions 55a, 55b and 55c spaced apart from one another in the ear-nose direction B. Each of the partial areas 55a, 55b and 55c serves as a deflecting surface for a light beam of the illuminating element 11g. For example, the partial area 55c may have a greater extent than the partial areas 55a and 55b arranged closer to the illuminating element 11g. This can make it possible, for example, for the partial area 55c to have areas which are not shaded by the partial areas 55a and 55b. For the same reasons, the partial area 55a can have a smaller extent than the partial area 55b. The reflection plate 52a is or its three partial areas 55a, 55b and 55c are designed to assume at least two different positions. A first position, in which the reflection plate 52a is arranged in order to couple light out of the coupling structure 12, is shown in FIG. 5e. In this position, the reflection plate 52a or its three partial areas 55a, 55b and 55c are arranged obliquely in such a way that a light beam from the illuminating element 11g is coupled out of the coupling structure 12a. For this purpose, it can include an angle β of 45 ° with the light beam emitted from the illuminating element 11g. In other exemplary embodiments, the angle β can also be in a range of values with an initial value of 35 °, 40 °, 45 °, 50 °, 55 ° and / or an end value of 40 °, 45 °, 50 °, 55 °, 60 ° lie.

5d shows a second position in which the reflection plate 52a is arranged or the three partial regions 55a, 55b and 55c thereof are arranged in order not to couple out light from the coupling structure 12a. Mostly, the reflection plate 52a will assume this position if the illuminating element 11g does not emit light. The reflection plate 52a is then arranged at a 90 ° angle to the beam path of the illuminating element. The user sees only narrow sides of the reflection plate 52a, so that the coupling-in structure 12a also appears transparent to him in the area which comprises the reflection plates 52 and the illuminating elements 11g, 11h, IIIi, IIj etc. The reflection plate 52a or its three sub-areas 55a, 55b and 55c each have a rectangular shape. In further, not illustrated embodiments, the reflection plate can also have a different shape, for example a different number of partial areas, only one, two or a larger number. Under certain circumstances, the partial area or areas can also have a shape that deviates from the present rectangular shape, for example square, polygon, triangle, round, oval, with openings and / or the like.

In summary, the reflection plate 52 and the illuminating elements 11g, 11h, IIi, IIj etc. in the exemplary embodiments of FIGS. 5a to 5f are embedded in an embedding layer, for example on a liquid crystal basis. The reflection plates 52 can be rotated from parallel (FIG. 5d) to an optical axis to oblique (FIG. 5e) by means of an electromagnetic field that is generated via the vapor-deposited conductor tracks 54a and 54b, and thus the LED light to the eye 4 redirect. A review can then possibly be ensured in the off state. In other exemplary embodiments, the embedding layer can also comprise a different material.

6a to 6d show schematic representations of an actuator 60 according to a further exemplary embodiment. Actuator 60 is essentially similar or structurally identical to actuators 10, 20, 30, 40 and 50, which is why differences or different features are mainly described below. The actuator 60 has a coupling structure 12 arranged at a distance from an eyeglass lens 122. This is arranged essentially parallel to the spectacle lens 122. The coupling structure 12 is closer to the user than the spectacle lens 122 in the user's direction of view when the actuator is worn in a correct use position. As shown, it can only be parallel to a partial area of the spectacle lens 122, in the present case one be provided in the upper section. It is also possible, for example, for a frame 15 to substantially obscure it in a user's viewing direction when viewed from above in a nose-forehead direction. The coupling structure 12 can be arranged, for example, in the viewing direction in such a way that the user's field of vision is not shaded or covered when the actuator 60 is worn in a correct use position. The coupling structure 12 has a smaller lateral extent than the spectacle lens 122 in the viewing direction of the user when the actuator 60 is worn in a correct position of use. The user thus maintains a clear viewing area which is essentially covered by the areas of the lens that are not covered in the viewing direction Breillenglass 122 is formed. In the present case, the coupling structure 12 is arranged above the see-through area.

[000100] The coupling structure 12 is arranged in the manner of a backdrop, spaced apart from the spectacle lens 122. The actuator 60 has at least two lighting-effective elements 11 a, b in the region of the nose bridge 17. During operation, these couple light beams in essentially opposite directions in parallel along the ear-nose direction into the coupling-in structures 12a, b.

Fig. 6b shows a section of a schematic sectional view of the actuator 60 of Fig. 6a. The spacing of the coupling structure 12 from the spectacle lens 122 is shown here. The Bril lenglas 122 is attached to the frame 15 regardless of the coupling structure 12. In some exemplary embodiments, the glasses 122a, b can be changed independently of the coupling structure 12a, b.

The embodiment according to FIGS. 6a-d has a coupling structure 12 with a reflection region 13 which has light-scattering and / or reflecting structures 56 formed by recesses. These lie on a surface of the reflection area 13. For example, they can be designed essentially like prisms. The structures 56 can lie on a side of the coupling structure 12 facing away from the user in the correct use position. This is shown schematically in Fig. 6 c and d. A light beam directed through the coupling structure 12 can be scattered on side surfaces of the light-scattering structures 56 and can be scattered or reflected in the direction of a user when the actuator 60 is used in the correct use position.

[000103] Furthermore, the exemplary embodiment according to FIGS. 6a-b has a mirror coating in the form of a reflection surface 21 on the at least one spectacle lens 122. This is provided in a region of the spectacle lens 122 which lies in front of the coupling structure 12 in the direction of view of a user who carries the actuator 60 in the correct use position. The reflection surface 21 can for example be essentially parallel to the coupling structure 12. So this is essentially not visible to a user of the user, it is covered by the mirroring. 6 is a partial mirroring of the spectacle lens 122. Additionally or alternatively, a mirroring of the entire spectacle lens 122 and / or a mirroring of the same can be provided on a side facing the coupling structure 12.

In summary, some embodiments of the actuator, which is designed as glasses, can have the following technical structure with regard to electronics. LED light sources are placed on a circuit board (PCB) as lighting-effective elements, e.g. lxweiß 6500K & lx RGB, a battery pack, driver electronics and communication components, e.g. for Bluetooth, etc. The LED light sources are located at the front end of the board. The circuit board is shaped in such a way that it is inserted into a recess in the temple and fixed with a cover and is tightly protected. The cover has a window for the LED light sources, so that light can emerge unhindered in a direction parallel to the lens. An electronics unit is installed in each of the two temple pieces. In some exemplary embodiments, this makes it possible for all components to be installed on a circuit board, including the LED, ie no wire jumpers and / or flexible line connections are necessary. The board is built into the bracket, possibly one Electronics in the glasses frame are partially or completely eliminated. Under certain circumstances, this can result in a reduction in sources of error, quick assembly and / or production, easier assembly, more cost-effective production and / or good sealability. Furthermore, the controls on the circuit board and on the bracket are easily accessible. The LEDs may be passively cooled due to the size of the board. The at least one sensor can also be arranged, for example, on the circuit board, on an inside of the temple with contact to the skin of the spectacle wearer. This may also result in good interchangeability in the event of faults in the electronics.

With regard to a mechanical structure, in some embodiments of the actuator, a spectacle frame and the glasses frame can be connected to one another in such a way that the frames for the glasses frame are detachably connected. The interface can be a joint, for example. Alternatively, the interface can also be arranged before or after the joint. The spectacle lenses can be mounted on the spectacle frame in such a way that they can be removed and e.g. can be replaced by dark tinted, colored or mirrored, for example partially mirrored glasses. A light guiding element, for example in the form of a light guide and / or a reflection area, for guiding and coupling out the LED light, can be mounted on the spectacle frame in such a way that the at least one LED couples its light as efficiently as possible into an edge of the light guiding element can. The light-guiding element can, for example, be placed in such a way that it is arranged between the eyes and the spectacle lenses in a correct use position of the actuator. Due to the mechanical structure described, a modular mechanical structure of the spectacle frame and temple, possibly with a tool-free fixing of glasses, light guide and temples, can be achieved in some exemplary embodiments. As a result, a lighter mechanical assembly can be achieved in some exemplary embodiments.

In some embodiments, a standardization of components, such as design variants can quickly be feasible. Then, for example, the temples can be combined with the electronics with spectacle frames in different sizes and / or designs. This may result in cost savings, component reduction, a reduction in development time and / or easier interchangeability. Easier interchangeability allows for customization, for example, it may be possible to provide different spectacle frames with different colors and / or designs to which the temples with the integrated electronics can be snapped on as desired. Furthermore, the components can be more easily separable, which can improve sustainability and / or recycling.

With respect to an optical system of the actuator can man in exemplary embodiments in the glasses frame next to conventional glasses that can serve as a coupling structure, the Lichtleitele element, which can also be referred to as a light guide, can be arranged. The light guide element can be arranged above the eye. Under certain circumstances, a user can then look through the spectacle lenses with unobstructed vision and thus perform visual tasks. Furthermore, the Lichtlei telement can be arranged such that the LED or the LED window comes to lie exactly on the outer edge of the light-guiding element when the eyeglass temple is open and can couple light into the light-guiding element through the clear, polished edge surface. The light-guiding element is then designed, for example, in such a way that a surface is provided on one side with a microstructure. The microstructure can, for example, be almost or completely invisible to a user, since the structural elements are smaller than the resolving power of the eyes. The light guide element can therefore appear transparently to the user. The microstructure can couple coupled light as far as possible to the eye. A microstructured light guide based on regular structures such as prismatic, conical, etc. shaped depressions or elevations, arranged in regular or with polynomial, linear, etc. increasing or decreasing density distribution, but also with stochastic shapes or Distribution over the surface enables in some embodiments Targeted and defined light coupling via edge coupling of the LED light from one or more sides.

In some embodiments, the described embodiments of the optical system can achieve high efficiency, since light is mainly directed and emitted towards the eye, i.e. only a few LEDs are necessary, which may result in a miniaturization of the PCB design and / or and increase the battery life or reduce the size of the battery. Under certain circumstances, direct glare can also be avoided, as the light guide technology can prevent a direct view of the LED or the LED chip. This may increase safety (eye safety) and visual comfort and reduce glare. Furthermore, an excellent mix of light from the white and an R.GB LED can result from multiple reflections in the Light Guide, for example as part of a total reflection. Under certain circumstances, a luminance can be produced very uniformly over the entire coupling area.

Compared to the prior art, in some embodiments, problems with respect to a high manufacturing complexity, too small illuminated areas, incorrect light direction, a disturbance in the field of view when wearing and using the actuator and / or protection against environmental influences, tightness and or fix and / or at least reduce. The above-mentioned problems are to be solved holistically by changing the structure of the electronics unit, including the placement of the LED light sources in conjunction with the optical principle. Some exemplary embodiments provide an actuator which both has sufficiently large luminous areas for both eyes, which are placed in an ideal position in order to be effective even with different facial physiognomies. In addition, the illuminated surfaces are transparent in some embodiments when switched off (ie without light). By suitably placing the illuminated surfaces, it may also be possible for the user to be able to carry out reading or other activities without hindrance, even during the light treatment. Apparatus and method have been described to illustrate the underlying idea based on some embodiments. The exemplary embodiments are not restricted to certain combinations of features. Even if some features and designs have only been described in connection with a special embodiment or individual exemplary embodiments, they can each be combined with other features from other exemplary embodiments. It is also conceivable to omit or add individual illustrated features or special configurations in exemplary embodiments, provided the general technical teaching remains implemented. Even if the steps of the method are described in a certain order, it goes without saying that each of the methods described in this disclosure can be carried out in any other meaningful order, wherein method steps can also be omitted or added, if not by that Basic ideas of the technical teaching described is deviated.
