Description

The invention relates to a luminaire, in particular telescopic luminaire, for illuminating construction and accident sites, craft and manufacturing facilities, workplaces, sports events and events, as well as in travel and leisure as a floor, flashlight or flashlight, comprising at least one element.

Luminaires are used in different variations for illuminating large areas indoors and outdoors as well as for illuminating smaller rooms. Thus, for example, to maximize the illuminated area, the illuminant is mounted as high as possible, for example in the interior of the ceiling or in the outer area of a mast. To make this mobile and to allow the highest possible attachment of the light source and the resulting increase in the illuminated area, preferably telescopic tripods are used. In such telescopic tripods several telescopic elements are interleaved and are extended via a guide mechanism either manually or via a drive relative to each other. This creates a mast, which consists of the telescopic elements and sometimes has a multiple of the original height of the telescoped telescopic stand.

Such a telescopic stand, for example, in the international application WO 2009 / 007284A1 described. The telescopic stand in this case comprises a plurality of tubular sections, which are pushed into one another. Furthermore, means are provided which serve to extend the inner telescopic segments of the outer telescopic segments. In this particular embodiment, a chain is provided which is attached to the first telescopic segment and attached to the subsequent telescopic elements, so that upon actuation of the chain, the individual elements are pulled apart. Conceivable here is also a manual operation, in which the individual telescopic elements are raised by hand and are provided with corresponding locking means to form a stable column.

Furthermore, it is known to use a telescoping technique in lights, as in the GB 1 460 025 A described. Here, a street lamp is shown, which consists of essentially two telescopic elements, wherein the lower telescopic element is designed as a protective cover or as a foot. The upper telescopic element is equipped with a conventional light source, such as a light bulb. The telescopic element is completely covered by the Teleskop in the untelected initial position. The telescopic element is additionally protected by the shell of the Teleskop. Furthermore, such a device allows the light source to be easily exchanged, since in the initial position the light source can be easily reached by a person on the ground, this being possible in the telescoped position only with additional aids, such as a ladder.

Furthermore, lights are known which consist of several elements which are not arranged telescopically, but rather consist of stacked elements. The elements used in this case each include a light source. The individual elements are then stacked up to the desired height. The resulting mast thus comprises a plurality of lighting means, which are arranged along the central axis of the mast. Such lights are often used outdoors for decoration purposes. Such lights are very unstable and thus represent a danger.

Furthermore, there are lights that consist of a luminous body, which is covered with a luminaire cover. Such lights can have a variety of forms and are used for advertising and decoration purposes in the outer and inner areas to attract the attention of the beholder. For this reason, the lights are often multicolored and form a logo. For example, such luminaires are used on rooftops and exterior walls to indicate the seat of a company.

On house surfaces also surface lights can be mounted, which are usually provided with a high density of LEDs on the outer surface. The LEDs have compared to traditional bulbs, such as light bulbs and gas discharge lights, a rather low luminosity and are therefore only limited use.

In existing luminaires, conventional illuminants are often replaced by newly developed LEDs. However, the problem that arises with this approach is that the conventional bulbs have a significantly greater luminosity per surface. If you replace these, for example, by LEDs, so the brightness of the lamp significantly reduced. For many types of lights, therefore, a mere replacement of the light source and the use of LEDs or the like is not possible with the same luminous area. LED's or so-called power LED's have a greater luminosity, as conventional LED's, but must be charged for large currents. With such a load, not only the luminosity, but also the generated one increases Warmth. This results in very high temperatures at the LED, which are not tolerated by normal versions. As far as the LED light is glued, there is a risk that the adhesive melts at high temperatures and the LED light drops from the bracket. As a result, LEDs are clearly limited in their luminosity and can only be charged with smaller currents.

The problem of small area is particularly pronounced with hand lamps. In the case of hand lamps, the light source is normally designed to be particularly small. In return, therefore, a particularly high light intensity of the lamp used is required. Conventional bulbs are here also very limited replaceable by LED's.

In most cases, the light intensity of LEDs is sufficient only for emergency lighting, which does not require high light intensity. Such lights can be found, for example, in baseboards of aircraft carpets, to indicate if necessary the way to the emergency exit and thus to provide guidance to persons in the dark.

The object of the invention is to provide a luminaire, which allows a uniformly large-area illumination or illumination using alternative bulbs.

According to the invention the object is achieved in that at least one outer surface of the at least one element is formed luminous. Further advantageous embodiments of the invention will become apparent from the dependent claims.

The luminaire according to the invention is designed as a telescope in contrast to the prior art. So far, tripods and telescopic fixings were only intended for attaching lamps or lights. The invention described here forms a telescope that is self-luminous.

The great advantage of the invention over the prior art is that a large surface of the lamp can be provided with a luminescent layer. The luminescent layer may in this case consist of an electroluminescent layer or a layer provided with LEDs. The luminaire can consist of a large number of telescopic elements. With each additional telescopic element, the area provided with a light bulb increases. The area can thus be made very large depending on the application. For example, construction and accident sites, a lot of light is needed to perform any work or rescue. In this case, several luminous telescopic elements can be used.

It is of particular importance that the light for transport can be pushed together particularly compact and in accidents, etc., for example, can be transported by a motor vehicle. The telescoping or collapsible light makes it extremely compact form and yet to achieve sufficient luminosity, for example, to illuminate an accident site such that the necessary rescue measures can be performed. To supply the LEDs and / or the electroluminescent luminescent layer, electrical connection elements are provided in this case. Here, a fastener for attaching the lamp is provided on a tripod. In a preferred manner, the telescopic element with the largest diameter is attached to the upper end of the stand. In a particularly preferred embodiment, the lamp telescopes automatically when hanging on a tripod. For example, it is conceivable that the telescopic elements are pulled apart only by gravity, or that the spiral element is helically stretched by gravity.

In one embodiment of the invention, it is conceivable to telescope the lamp either by hand or to provide a drive for telescoping the lamp for particularly large and multiple elements.

The lamp can also be designed as a flashlight or flashlight. Here, the telescoping or collapsibility allows a small congestion, so that the lamp can be easily stored in a bag. If necessary, the lamp is pulled apart to ensure a greater light intensity for lighting. Such a flashlight could replace, for example, a tail lamp for craftsmen. With limited space and tight installation conditions, the telescopic luminaire can be pulled out only to a part and adapted to the appropriate dimensions. For example, a craftsman can attach the luminaire to a hook in small attics or cellars and, depending on the necessary intensity, pull the telescope elements apart. For example, this is of particular advantage in heating construction, in electrical installations, in repair shops of vehicles or aircraft and similar applications in which the available space is particularly limited. The fastener can be used here as a handle.

For pulling apart the luminaire according to the invention, it is provided that at least one spiral element is helically stretched. Here, the spiral element forms a wound light strip in the undressed position. Will the light pulled out, created from the wound light strip a three-dimensional helix. The inherent stability of the spiral element forms the necessary spring force to maintain the helical structure.

Furthermore, it is possible to form the telescopic lamp from a plurality of telescoping telescoping telescoping elements. Here, the smaller telescope elements are nested in the next larger elements.

In a particularly advantageous manner, it is provided that the telescopic element is designed to be multi-layered, wherein at least one guide element is provided with a lighting, cooling, focusing and / or protective layer. The layers can be used either individually or in any combination.

Of particular importance is the guide element, which has at least one guide means for telescoping the lamp, which consists of at least one guide spring and a guide groove and is self-centering. The guide means are essential to allow telescoping of the lamp. In each case, guide means may be provided corresponding to the inner and the outer side of the inner telescopic elements. Thus, the guide means engage each other and allow it to telescope the lamp along the guide means. For example, the guide spring engage in a guide groove, which is provided with additional fastening means to lock the guide spring in the guide groove. In addition to the guide means, further aids for telescoping, such as, for example, a carrier mounted in the center of the telescope elements, a telescoping chain or a cable, may be provided. Such a support may for example be provided with a fastener or with a foot to connect the individual telescopic elements together and, for example, with a hook attached to a wall or ceiling. A trained as a foot element telescopic element makes it possible to set up the telescopic light securely on the ground and the carrier makes it possible to keep the telescopic light in the telescoped position. Here either a telescopic chain or a rope can be used. The Teleskopierkette or the rope can be attached to the upper telescopic element and is guided to the lower end. At the bottom, the rope is used either manually or via a drive to pull the luminaire and the individual elements apart along the guide means. In this case, fastening means may be provided on the guide spring or on the guide groove in order to lock the individual elements in different positions. These may be formed, for example, as a locking pin or as a corresponding hook or taper. Here, the telescoping elements, for example, sensor or electromechanical, are switched so that only the fully telescoped telescopic elements shine. This makes it possible to use the telescopic light in a not completely telescoped state. Furthermore, pressure rollers can rest on the outer surface of the telescopic elements and extend in a rotary drive the individual telescopic elements upwards.

Alternatively, the lamp can be telescoped or pushed apart by a spiral spring located inside the lamp. In such an embodiment, the coil spring may for example be slightly conical mounted inside the lamp. The spiral spring may be held together or biased to transport the non-telescoped or extended lamp via a clamping mechanism. Removing this clamping mechanism, the coil spring is relaxed and pushes the lamp in an extended position, this end position is held by the spring pressure of the coil spring.

The luminescent layer can either be formed electroluminescent or sufficiently dense with LED lights, power LEDs, an LED foil, permanent LED's and / or be provided with LED chips. The big advantage of using such alternative bulbs over conventional bulbs is the high efficiency of the LED. This can save up to 90% of the electricity requirement. When using an electroluminescent layer further savings are possible.

Especially the further developments of the LED's makes it possible to provide the surface of a luminous element with an electroluminescent layer. This gives you a luminous element that shines over its entire surface and not just selectively as with LEDs. In such electroluminescent layers, however, the problem arises as with LEDs, namely, that the luminosity is too low for a given area to allow a large-area illumination. To use such luminescent layers for lighting and out, the body of the lights must be appropriately large equipped. This possibility is created by the telescopic luminaire, so that even a lighting and illumination of construction and accident sites, craft and manufacturing facilities, jobs, sporting events or other events is possible.

In order to ensure a sufficient brightness of the lamp, the LED's or the electroluminescent layer with appropriate Be operated currents. This produces waste heat, which must be dissipated. For this purpose, a cooling layer is provided, which is in thermal contact at least with the luminescent layer. The cooling layer consists for example of a convection cooling by natural air flow or forced cooling using water or air. Preferably, this cooling layer is provided inside the elements. The cooling layer is shaped, for example, as a cooling plate, preferably made of metal. Thus, the heat can be delivered either to the outside air flowing through the elements or via a separate water cooling system within the telescopic elements. Such a cooling layer is of particular importance when at high currents, the temperature can rise dramatically and u. U. damage to the luminescent layer should be avoided.

Furthermore, it is also possible to compensate for the lack of brightness per unit area by an enlarged area by enlarging the area. This reduces at the same time the effort required to cool the lamp.

The further development of LEDs or electroluminescent layers also improves the illustrated telescopic luminaire and increases its efficiency in the field of use.

For convection within the elements, for example, contribute to a setting gap at the foot of the lamp. Through this setting gap creates an opening through which the air can pass from bottom to top through the entire lamp. Through the air flowing through the lamp is cooled. The heat generated in the luminescent layer is dissipated by this and the luminescent layer can be operated accordingly with higher currents, which leads to an increase in light intensity and better illumination.

The telescopic elements can assume essentially any shape. In a particularly advantageous manner triangular, polygonal and round cross sections are provided. Depending on the field of application of the telescopic luminaire, the cross section can be adjusted. For example, a round cross section is particularly suitable for a handbag lamp.

In a further advantageous embodiment, the luminaire can be provided with a focusing layer, which comprises spaced-apart focusing elements, wherein an LED is arranged on the underlying luminous layer between in each case two focusing elements. Hereby the lamp can be used as a diffuser or floodlight. Thus, with appropriate alignment of the focusing layer on the luminescent layer, a scattered light can be generated. The focusing layer with the focusing elements can also be mounted rotatably relative to the luminescent layer. This makes it possible for the focusing elements to be rotated in such a way that they coincide on the LEDs. In this position, the light of the LED's is focused and one receives directional light. This may be important, for example, if the lights should not be used for large-area illumination, but for selective illumination, such as in a flashlight or in a larger configuration by a so-called spot light. The focusing layer or the focusing elements can be made of glass or glass-like plastic, such as polycarbonate or acrylic. In general, any material is conceivable which is also used in the manufacture of lenses. In particular, when using such a focusing layer, it is advantageous if in addition an outer protective layer is used. This can for example consist of a particularly tempered glass or plastic. A further embodiment possibility is to attach the focusing elements inwardly in the direction of the LED's. This creates a smooth outer layer that is less susceptible to damage.

An energy saving option is to design the lamp such that the outermost telescopic element always and the inner telescopic elements shine only in the telescoped position after switching. This is particularly advantageous if the luminaire is often used in a not or not fully telescoped position. Here you can disconnect the inner telescopic elements of the power supply and illuminate only visible to the outside telescopic elements. This is possible, for example, via the fastening means provided in the guide layer. When locking this, the corresponding telescopic element or the luminescent layer is supplied with voltage.

The connecting elements can be configured, for example, as a sliding contact of elements to element, with a switch on and off possibility. Moreover, it is conceivable that the connection elements of the individual telescopic elements are connected to an external power supply or a battery integrated in the lamp.

Furthermore, it is conceivable, in order to produce a directed light beam, to provide on the outer surface of the telescopic lamp a reflector which covers either individual telescopic elements or the entire luminaire over at least a partial circumference. For this purpose, a roller can be provided to wind the reflector. By such a reflector, the light is not on the Whole circumference radiated, but the entire light intensity emitted over the not covered by the reflector surface. Thus, if necessary, the light intensity can be increased in a preselected direction. In addition, it is possible to shield light in a certain direction. This could, for example, when used as a flashlight serve to not dazzle the user. For lights to illuminate accident or construction sites, this could serve to not blind the drivers of arriving cars unnecessarily.

The invention will be explained in more detail below with reference to FIGS.

The guide means engage each other and thus make it possible, the lamp 1 telescope along the guide means. In addition, as a tool for telescoping, for example, a carrier, a Teleskopierkette or a rope may be provided. The fan 3 serves for convection cooling of the telescopic elements 2 , The fan 3 creates a draft within the lamp 1 through which the telescopic elements 2 be cooled by the operation of the lamp 1 dissipate generated heat. The fan 3 is to be regarded as optional, as a natural air convection when using the lamp 1 occurs. Furthermore, the fan can 3 be distracting when the light 1 as a flashlight or flashlight is used, so in this case on the fan 3 can be omitted, especially as in a smaller version of the lamp 1 the resulting heat is relatively low and requires no additional convection cooling.

To operate the lamp 1 it is still possible to have a battery 7 to use which the light 1 supplied with sufficient voltage. This is especially true for small and extremely mobile lights 1 especially advantageous. For larger lights 1 It is still quite conceivable to provide a battery, but this is with increasing luminous area of the telescopic elements 2 too large.

In conjunction with the fan 3 This creates a pull through the lamp 1 for cooling the telescopic elements 2 serves. Especially with a sufficient height of the lamp 1 is a fan 3 not necessarily necessary to provide adequate airflow within the luminaire 1 to create. This can also be due to the natural convection of the lamp 1 Cool enough.
