Detailed Description

In the present invention, in the case where no explanation is given to the contrary, the position or positional relationship indicated by the use of the positional terms such as "front and rear" is based on the position or positional relationship shown in the vehicular lamp lighting device of the present invention. The utility model discloses a car light lighting device's light-emitting direction is "preceding", and is "back" rather than relative direction.

In the present invention, the term "light distribution element" refers to a light element that can change the propagation direction of all or a part of light to change the original light distribution. The way of changing the propagation direction of the light can be reflection, refraction or any other possible way. The term "concentrator" refers to an optical device that focuses light in at least one direction as it passes through.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; either directly or indirectly through intervening media, either internally or in any combination thereof. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings, and it should be understood that the embodiments described herein are merely for purposes of illustration and explanation, and the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 and 2, one embodiment of the vehicle lighting device of the present invention includes a light source 1, a rotary actuator 2, a light distribution element 3, and a controller. The light source 1 is provided with a plurality of light emitting units 11 which are arranged in sequence and can independently emit light. The light emitting unit 11 is selected from light emitting elements capable of rapid light emission and rapid light extinction, and preferably light emitting elements having sufficient light emission intensity and a small volume. The utility model discloses in can choose for use LED, laser diode etc.. The light distribution element 3 is arranged at a position close to the light source 1 and used for converging light rays emitted by the light emitting unit 11, so that on one hand, the illumination brightness of the light rays emitted by the light emitting unit 11 can be improved, on the other hand, the mutual influence among the light rays emitted by different light emitting units 11 can be avoided, and the precision of the formed light shape is improved. The light distribution element 3 may be a reflector cup 31 disposed on a side surface of the light source 1, a light collector 32 disposed in front of the light source 1, or any other device capable of collecting light. The light source 1 is attached to a rotation shaft of the rotary actuator 2 and can be rotated at high speed by the drive of the rotary actuator 2. The plurality of light emitting units 11 are arranged from the rotation center of the light source 1 to the outer periphery, and in the present embodiment, the specific arrangement of the light emitting units 11 is not limited, but the linear distance of the outermost light emitting unit 11 from the rotation center determines the light emitting range. The gaps between the light emitting units 11 may be equal or unequal, and may be adjusted by those skilled in the art according to the optical performance. In order to maintain the balance of the light source 1 in the high-speed rotation state, a corresponding blank area needs to be reserved on the opposite side of the light emitting unit 11 arrangement area of the light source 1. The light distribution element 3 may be attached to the rotary actuator 2 or may be attached to the light source 1 so as to be rotatable in synchronization with the light source 1. The balance in the rotating state of the rotary actuator 2 should also be taken into account when setting the light distribution elements 3. The rotary actuator 2 is selected from a rotary driving device capable of rotating at a high speed and feeding back a rotation state, such as a direct current motor with a rotation speed feedback electrode. A rotation driving device such as a servo motor whose rotation speed can be precisely controlled may also be used. The controller (not shown in the drawings) can receive the rotation speed signal of the rotary actuator 2 and respectively control the light-emitting units 11 to be turned on or off at each moment according to the rotation speed of the rotary actuator 2, so that the light-emitting units are in the same on-off state at the same rotating position within a certain time, and a fixed light shape is formed under the action of the principle of persistence of vision. The light shape formed by changing the on-off state of each light-emitting unit 11 at a specific moment; the on-off state of each light-emitting unit 11 in the unit time period is controlled to change slowly according to a certain rule, and animation light shapes can be formed. When the rotating speed of the rotary actuator 2 reaches 25 revolutions per second, namely 1500 revolutions per minute, a more stable light shape can be formed. The higher the rotation speed of the rotary actuator 2, the better the stability of the light shape, and in the present embodiment, a rotation speed of 3000 rpm is recommended. As shown in fig. 3, the rotary actuator 2 can rotate clockwise or counterclockwise, and the rotation direction is only related to the control program of the controller and does not affect the implementation of the functions of the present invention. The increase of 11 numbers of light emitting units per unit length can improve the illumination accuracy or display resolution of the vehicle lighting device of the present invention. The use can send the luminescence unit 11 of high luminance white light, the utility model discloses a vehicle lighting device can be used for replacing the matrix headlight, uses lower luminance colour luminescence unit 11, the utility model discloses a vehicle lighting device can be used for replacing pixelization signal lamp. The controller uses a 51-series single chip microcomputer which is widely used at present, and the MCS-51 single chip microcomputer is used in the embodiment, the control and programming method of the controller is well known to those skilled in the relevant field, and the present invention is not improved in this respect, so the details are not described herein.

As shown in fig. 1 and 2, the lighting device of the present invention may further include a bracket 6, and the rotary actuator 2 is mounted on the bracket 6 and fixed to the lamp body through the bracket 6. The related components are connected by conventional connection methods such as welding, riveting, screw connection or gluing, and the like, so as to achieve the functions described in the specification. The light source 1 is powered by conventional rotatable power supply means, preferably by conductive slip rings, to power the light source 1. The power supply structure is not shown in the drawings. The controller may be integrated on the circuit board of the light source 1, or integrated in the rotary actuator 2, or externally connected to the apparatus in the form of a separate circuit board.

In some embodiments of the present invention, as shown in fig. 1 and fig. 2, the vehicle lighting device of the present invention further includes a mounting plate 4, the center of the mounting plate 4 is fixed on the rotation axis of the rotary actuator 2, the light source 1 and the light distribution element 3 are mounted on the mounting plate 4, the light emitting units 11 on the light source 1 are arranged along the center of the mounting plate 1 toward the edge of one side, and the light distribution element 3 is disposed on both sides of the arrangement direction of the light emitting units 11. When the rotary actuator 2 rotates, the mounting plate 4 is driven to rotate, and then the light source 1 and the light distribution element 3 are driven to rotate together around the rotating shaft of the rotary actuator 2. The mounting plate 4 can be made of an insulating material with a certain mechanical strength, and preferably made of a high thermal conductivity insulating plastic, so that the mounting plate can be well fixed on the rotating shaft of the rotary actuator 2, and can better support the light source 1, prevent the light source 1 from vibrating or deforming in the high-speed rotating process, and ensure the stability of the formed light shape.

In some embodiments of the inventive vehicle lighting device, each light emitting unit 11 of the light source 1 is located on a different radius of rotation of the rotary actuator 2. At this time, the rotation locus of each light emitting unit 11 forms a circle of a different radius when the rotary actuator 2 rotates one revolution, and each light emitting unit 11 constitutes a different pixel in the rotation plane at each moment in the rotation process. Thus, the resolution of the formed light shape is higher. The individual light-emitting units 11 may be arranged on a line segment which passes through the axis of rotation of the rotary actuator 2 at one end, on a plurality of line segments which pass through the axis of rotation of the rotary actuator 2 at one end, or even scattered on a circle centered on the axis of rotation of the rotary actuator 2. Since the light emitting units 11 occupy a certain area and a certain gap exists between adjacent light emitting units 11, the number of light emitting units 11 that can be disposed in one radial direction is limited, which limits the accuracy of the illumination light shape or the resolution of the display of the vehicle illumination device. The light-emitting units 11 are dispersedly arranged at different positions, so that the number of the light-emitting units 11 on different rotating radiuses is larger, the light-emitting units 11 on different radiuses are specially controlled, namely, the arrangement density of the light-emitting units 11 on the same radius is improved, the illumination precision or the display resolution of the vehicle lighting device can be effectively improved, the limitation of the packaging volume and the arrangement distance of the light-emitting units 11 is broken through, and the larger light form resolution is obtained.

In some embodiments of the vehicle lighting device of the present invention, as shown in fig. 4 to 6, each light emitting unit 11 of the light source 1 is divided into two or more groups, each group is installed in a different region of the rotation plane of the rotary actuator 2, and each light emitting unit 11 within each group has a different rotation radius. The light emitting units 11 in different groups may have the same rotation radius or different rotation radii, but when the rotation radii are the same, the number of light emitting units 11 in each group is generally equal, and the corresponding light emitting units 11 have the same rotation radii. The light emitting units 11 of each group can be linearly arranged along a radius of the rotating circle of the rotating actuator 2, and also can be arranged according to other arrangement modes in different areas of the rotating plane of the rotating actuator 2, for example, the light emitting units 11 can also adopt a plurality of arrangement modes from the circle center to the circumference, such as inclined arrangement, involute arrangement and the like, and the relative positions of the light emitting units 11 on the circumference can also be diversified, so as to enrich the lighting and/or signal functions of the vehicle lighting device.

As an embodiment of the vehicle lighting device of the present invention, as shown in fig. 4 to 6, the plurality of light emitting units 11 are divided into at least two groups, and the corresponding light emitting units 11 in each group are symmetrically arranged on the rotation circumference of the rotary actuator 2. For example, as shown in fig. 4, the light emitting units 11 of the light source 1 are linearly arranged along a line segment having the rotation axis of the rotary actuator 2 as a midpoint, that is, the light emitting units 11 are arranged at two symmetrical radii of a rotation circle generated by the rotation of the light source 1 around the rotation axis of the rotary actuator 2. Alternatively, as shown in fig. 5, the light emitting units 11 of the light source 1 are arranged along three equal-length line segments of 120 ° in sequence from the rotation axis of the rotary actuator 2, that is, the light emitting units 11 are arranged at three centrosymmetric radii of a rotation circle generated by the rotation of the light source 1 around the rotation axis of the rotary actuator 2. Alternatively, as shown in fig. 6, a circular mounting plate 4 is provided, the center of the mounting plate 4 is fixed on the rotation axis of the rotary actuator 2, and the light sources 1 are arranged on 6 symmetrical radii of the rotation circle of the rotary actuator 2 from the center of the mounting plate 4 to the circumferential direction. The arrangement of the light emitting units 11 on symmetrical radii can ensure the balance of the light source 1 in a rotating state, and the controller is convenient to program. In this state, the rotary actuator 2 can make the light emitting unit 11 cover the whole circle of rotation only by rotating one half (the light emitting unit 11 is located on two radii) or one third (the light emitting unit 11 is located on three radii), the rotary actuator 2 can make the light emitting unit 11 scan three times on the same circle by rotating one circle, the brightness of the vehicle lighting device is greatly improved, and the precision or the resolution ratio is not changed.

In some embodiments of the present invention, as shown in fig. 1 and fig. 2, the vehicle lighting device of the present invention is further provided with a lens 5, and the lens 5 is used for projecting the light emitted from the light source 1 to form a specific light shape. The use of the lens 5 can make the light shape projection distance formed by the vehicle lighting device of the present invention farther. The light source 1 is generally disposed near the focal position of the lens 5 to form a clearer projected light shape. The lens can be made of glass, plastic, rubber and other materials; a plano-convex lens as shown in fig. 1 and 2, a biconvex lens, or a lens group formed by combining several lenses may be used. The optical axis of the lens 5 is typically parallel to the axis of rotation of the rotary actuator 2. Preferably, the optical axis of the lens 5 is collinear with the axis of rotation of the rotary actuator 2. When the optical axis of the lens 5 and the rotation axis of the rotary actuator 2 are on the same straight line, the light emitted from the light source 1 is projected right in front of the lens, and the deformation of the light shape is small. The optical axis of the lens 5 is parallel to the rotation axis of the rotary actuator 2 but offset to adjust the position of the light shape and the coupling between the light shapes of the various parts. The deviation between the two is not too large, and is generally a deviation of millimeter level. Based on the principle of lens imaging, when the lens 5 is used, the light projected on the road surface is opposite to the light emitted by the light source 1, and the program for controlling the light-emitting unit 11 to be turned on and off by the controller needs to be re-programmed.

In some embodiments of the vehicle lighting device of the present invention, as shown in fig. 7 to 12, the light distribution element 3 is a reflector 31 disposed in the area on both sides of the light emitting unit 11. The reflection plates 31 are disposed at both sides of the light emitting unit 11 to limit light emitted from the light emitting unit 11 within a certain range. As shown in fig. 10 and 12, the large-angle scattered light emitted by the light-emitting unit 11 irradiates on the reflector 31, and is reflected by the reflector 31 to emit to the front of the light-emitting unit 11, so that the light emitted by the light-emitting unit 11 is converged in a certain range in front of the light-emitting unit 11, thereby reducing the scattering of the light-emitting unit 11 and improving the light shape brightness and the display precision of the car light illuminating device. The light reflection plate 31 may be provided on the light source 1, or may be provided on the mounting board 4 for mounting the light source 1. A set of light reflecting plates 31 may be disposed on both sides of each light emitting unit 11, or a set of light reflecting plates 31 may be disposed on both sides of a plurality of light emitting units 11.

In some embodiments of the lighting device of the present invention, as shown in fig. 7 to 10, the light reflecting surface of the light reflecting plate 31 is a curved surface. The reflecting surface of the curved surface can better control the reflecting direction of the reflected light, and the convergence degree of the light emitted by the light emitting unit 11 is improved. In other embodiments of the lighting device for vehicle of the present invention, as shown in fig. 11 and 12, the light reflecting surface of the light reflecting plate 31 is a flat surface. The planar reflecting surface has a simple structure, is convenient to process, and can also realize the purpose of reflecting the large-angle scattered light emitted by the light emitting unit 11 so as to improve the convergence degree of the light emitted by the light emitting unit 11. Each of the reflection plates 31 may be disposed at one side of the plurality of light emitting cells 11. When the light emitting units 11 are grouped, one light reflecting plate 31 may be disposed on each of both sides of each group. The side of a plurality of luminescence units 11 sets up a set of reflector panel 11 and can reduce the quantity that sets up of reflector panel, improves car light lighting device's stability.

In some embodiments of the vehicle lighting device of the present invention, as shown in fig. 13 to 24, the light distribution element 3 is a light-gathering member 32 disposed in the light-emitting surface area of the light-emitting unit 11. The light-gathering member 32 is mostly a transparent solid body made of a transparent material. It can be made of transparent plastic, silica gel, etc., and PMMA or PC is preferred. The light gathering member 32 has a plurality of light incident surfaces and light emitting surfaces, and each light incident surface and/or light emitting surface may correspond to one or more light emitting units 11. The light emitted by the light emitting unit 11 is guided into the light gathering member 32 from the light incident surface of the light gathering member 32, and is converged and blended by the light gathering member 32, and then is emitted from the light emitting surface of the light gathering member 32, so as to improve the convergence degree of the light emitted by the light emitting unit 11, and improve the lighting effect and the light shape definition.

In some embodiments of the vehicle lighting device of the present invention, as shown in fig. 13 to 24, each light condensing member 32 is disposed in the light emitting surface area of the plurality of light emitting units 11.
