[0001] The present invention belongs to the technical field of vehicle lamps, and particularly relates to a vehicle lamp and an automobile. Background Art

[0002] To achieve the hierarchical styling (comprehensible effect and discrete effect) of the large light-emitting surface of the daytime running light and the front position light of a vehicle lamp, the commonly used light-emitting forms include using an optical waveguide plus other independent light sources (independent optical waveguides and independent LEDs) to achieve the hierarchical styling theme through discrete lighting, using a condenser plus other independent light sources (independent LEDs) to achieve the hierarchical styling theme through discrete lighting, and using a condenser plus other independent light sources (LED side-illuminated free-form surface) to achieve the hierarchical styling theme through discrete lighting. However, these solutions have the problem that multiple groups of independent light sources need to be arranged to light up the discrete areas, resulting in high power consumption and high cost.

[0003] In the prior art, for example, the patent with the publication number CN114234128A discloses an optical waveguide optical system for saving space and achieving uniform lighting and its vehicle signal lamp. This vehicle signal lamp includes a light source, and the light source is correspondingly arranged at the end of the optical waveguide; an inner lens is correspondingly arranged above the optical waveguide, and an optical waveguide bracket is correspondingly arranged below the optical waveguide; the optical waveguide includes an optical waveguide total reflection optical tooth and an optical waveguide styling total reflection surface, the optical waveguide total reflection optical tooth is formed on the optical waveguide, and the optical waveguide total reflection optical tooth is correspondingly arranged on the light-incident surface of the inner lens; a first diffusion optical pattern is formed on the optical waveguide bracket, and the first diffusion optical pattern is correspondingly arranged on the optical waveguide styling total reflection surface. However, this vehicle signal lamp has the problem that there are multiple groups of light sources when the vehicle signal lamp realizes the hierarchical styling of a large light-emitting surface, resulting in high power consumption and high cost. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that there are multiple groups of light sources when the vehicle signal lamp realizes the hierarchical styling of a large light-emitting surface, resulting in high power consumption and high cost.

[0005] To solve the above technical problems, the present invention discloses a vehicle lamp. When the vehicle lamp is installed on a vehicle, the width direction of the vehicle lamp is parallel to the length direction of the vehicle, and the vehicle lamp has an inner side of the lamp facing the inside of the vehicle and an outer side of the lamp facing the outside of the vehicle along its width direction; the vehicle lamp includes a light source and a light guiding component, and the light guiding component includes a light conductor extending along the length direction of the vehicle lamp, a light transmissive member, and a light homogenizing member; one end face of the light conductor forms a first incident surface, and the light emitting end of the light source is arranged facing the first incident surface; the outer periphery of the light conductor has a light guiding tooth surface and a first emitting surface along its circumferential direction, the light guiding tooth surface is located on the side of the light conductor close to the inner side of the lamp, and is straight in the cross section of the light conductor, and light guiding teeth are arranged on the light guiding tooth surface; the first emitting surface includes an arc surface; the light transmissive member is arranged on the outer side of the lamp, and the side surface of the light transmissive member on the outer side of the lamp is a second emitting surface, the side surface facing the inner side of the lamp is a second incident surface, and the first part of the first emitting surface is arranged opposite to the first part of the second incident surface; the light homogenizing member is arranged on the side of the light conductor close to the outer side of the lamp, and the side surface of the light homogenizing member facing the inner side of the lamp is a third incident surface, and the side surface facing the outer side of the lamp is a third emitting surface; and at least part of the third incident surface is arranged opposite to the second part of the first emitting surface.

[0006] Adopting the above technical solution, the light conductor conducts the light emitted by the light source to the entire length direction of the vehicle lamp, and the light guiding teeth on the light guiding tooth surface of the light conductor can change the light emitting angle of the light, so that the light is refracted to the first emitting surface, and the arc part of the first emitting surface enables the light emitting range angle of the light to cover multiple directions; the light emitted from the first part of the first emitting surface can enter the first part of the second incident surface of the light transmissive member, and then is emitted from the second emitting surface of the light transmissive member. Since the material of the light transmissive member has excellent light transmissive performance, the loss during the light propagation process is very small, so the clear effect can be achieved, and thus the vehicle lamp can meet the regulatory requirements.

[0007] The light emitted from the second part of the first emitting surface of the light conductor can enter the third incident surface of the light homogenizing member, and after being evenly scattered, is emitted from the third emitting surface, realizing the uniform lighting effect, that is, the discrete effect, when the light emitting area of the light homogenizing member is relatively large.

[0008] The vehicle lamp provided by the present invention only needs a set of light sources. Through the functions of the light guiding component, on the basis of meeting the regulatory requirements for the light distribution effect, the clear effect of the light transmissive member of the vehicle lamp and the uniform discrete effect of the light homogenizing member can be achieved under a large light emitting area, reducing the power consumption and cost caused by multiple light sources.

[0009] According to another specific embodiment of the present invention, the light homogenizing member of the vehicle lamp disclosed in the embodiment of the present invention is arranged on one side of the second incident surface of the light transmissive member, and the third emitting surface is arranged opposite to the second part of the second incident surface.

[0010] With the above technical solution, the light-transmitting member is disposed outside the vehicle lamp, and the light homogenizing member is closer to the inside of the vehicle lamp than the light-transmitting member. Thus, the light guide teeth on the light guide tooth surface change the light exit angle, so that after the light is refracted to the second part of the first exit surface, it enters the third entrance surface of the light homogenizing member, and after being uniformly scattered, it exits from the third exit surface of the light homogenizing member, realizing the uniform lighting effect of the light homogenizing member, that is, the discrete effect. And the light is directed to the second part of the second entrance surface of the light-transmitting member opposite thereto, and the angle of the light does not shift between the second part of the second entrance surface and the second exit surface of the light-transmitting member, and is directly emitted through the second exit surface of the light-transmitting member.

[0011] According to another specific embodiment of the present invention, the light guide assembly of the vehicle lamp disclosed in the embodiment of the present invention further includes a light guide bracket and a reflective bracket extending along the length direction of the vehicle lamp; the light guide bracket is disposed on the side of the light conductor closer to the inside of the vehicle lamp, and the side of the light guide bracket close to the light conductor is the fourth entrance surface, the side of the light guide bracket away from the light conductor is the fourth exit surface, and the fourth entrance surface is disposed opposite to the light guide tooth surface; the reflective bracket is disposed inside the vehicle lamp, and the side of the reflective bracket facing the outside of the vehicle lamp is the reflective surface, and the reflective surface of the reflective bracket is respectively disposed opposite to the fourth exit surface and the third entrance surface.

[0012] With the above technical solution, after the light emitted by the light source is incident on the first entrance surface, it can be refracted by the light guide tooth surface and then directed to the fourth entrance surface of the light guide bracket, and can exit from the fourth exit surface. The reflective bracket is closer to the inside of the vehicle lamp than the light guide bracket. Thus, the light exiting from the fourth exit surface of the light guide bracket can be directed to the reflective surface of the reflective bracket, and after being reflected by the reflective surface, it can be directed to the third entrance surface of the light homogenizing member, and after being uniformly scattered, it exits from the third exit surface of the light homogenizing member, further realizing the uniform lighting effect of the light homogenizing member, that is, the discrete effect. And the light is directed to the second part of the second entrance surface of the light-transmitting member opposite thereto, and the angle of the light does not shift between the second part of the second entrance surface and the second exit surface of the light-transmitting member, and is directly emitted through the second exit surface of the light-transmitting member, making the hierarchical shape of the clarity effect and the discrete effect more obvious.

[0013] According to another specific embodiment of the present invention, diffusion patterns are provided on the first part of the second entrance surface and the reflective surface of the vehicle lamp disclosed in the embodiment of the present invention.

[0014] With the above technical solution, by providing diffusion patterns on the first part of the second entrance surface and the reflective surface, the light can be uniformly diffused, changing the reflection or refraction angle of the light, and making the light diverge from multiple angles.

[0015] According to another specific embodiment of the present invention, the diffusion patterns of the vehicle lamp disclosed in the embodiment of the present invention are a plurality of strip-shaped patterns or a plurality of square patterns arranged in an array, and the width of each strip-shaped pattern or square pattern is 0.5 mm - 2 mm.

[0016] With the above technical solution, the diffusion lines are arranged as a plurality of strip lines or a plurality of grid lines in an array, so that the light is evenly diffused in multiple directions between the gaps of the lines, which can expand the light refraction and reflection areas of the light-transmitting member and the reflective bracket, and can eliminate the light spot.

[0017] According to another specific embodiment of the present invention, for the vehicle lamp disclosed in the embodiment of the present invention, along the height direction of the vehicle lamp, the light guide bracket and the reflective bracket are arranged on the lower side of the vehicle lamp, and the light homogenizing member is arranged on the upper side of the light conductor; and the light guide bracket and the reflective bracket are arc-shaped structures protruding towards the inner side of the vehicle lamp.

[0018] With the above technical solution, the fourth incident surface, the fourth exit surface of the light guide bracket and the reflection surface of the reflective bracket are also arc-shaped surfaces, so that the range angles of light incidence, exit and reflection cover multiple directions.

[0019] According to another specific embodiment of the present invention, the light conductor, the light-transmitting member, the light homogenizing member, the light guide bracket and the reflective bracket of the vehicle lamp disclosed in the embodiment of the present invention are made of polycarbonate material; the height of the light-transmitting member is 4 mm - 35 mm, and it has a laser engraving pattern.

[0020] With the above technical solution, since the polycarbonate material has excellent light transmittance, good mechanical properties, flame retardancy and high temperature resistance, it can be used as the preferred material for the light conductor, the light-transmitting member, the light homogenizing member, the light guide bracket and the reflective bracket. Making a laser engraving pattern on the surface of the light-transmitting member, performing black paint spraying and laser engraving treatment can process various surface texture effects, improving the appearance texture of the vehicle lamp.

[0021] According to another specific embodiment of the present invention, the light source of the vehicle lamp disclosed in the embodiment of the present invention has two chips, which respectively emit lights of different colors.

[0022] With the above technical solution, two chips capable of respectively emitting lights of different colors are arranged in the light source, and single or multiple simultaneous lighting of signal lights of different light colors can be realized according to requirements. For example, single lighting of signal lights such as daytime running lights, front and rear position lights, brake lights, front and rear turn signals, etc., or simultaneous lighting of two of the above signal lights through two light colors.

[0023] According to another specific embodiment of the present invention, the vehicle lamp disclosed in the embodiment of the present invention further includes a circuit board and a radiator; the circuit board is installed on the radiator, and the light source is installed on the circuit board.

[0024] With the above technical solution, the light source and other controllers are connected to the circuit board to directly control the light color of the light source, etc., and the radiator can dissipate the heat generated by the long-term use of the vehicle lamp light source, avoiding the risk of high-temperature ablation.

[0025] According to another specific embodiment of the present invention, an embodiment of the present invention discloses an automobile including a vehicle lamp.

[0026] By adopting the above technical solution, for an automobile equipped with the vehicle lamp provided in the above embodiment, since the vehicle lamp only uses a set of independent light sources, compared with the vehicle lamps in the prior art that use multiple sets of independent light sources to respectively achieve the clear effect and the discrete effect, the functional loss of the automobile is reduced, the cost is reduced, and when the area of the light-emitting surface is relatively large, the vehicle lamp can also achieve the effect of layered light emission and uniform lighting.

[0027] The beneficial effects of the present invention are as follows:

[0028] The present invention provides a vehicle lamp and an automobile. The vehicle lamp includes a light source, a light guide assembly, a circuit board, a radiator, etc. Among them, the vehicle lamp only has a set of independent light sources. The light guide assembly includes a light conductor disposed at the light-emitting end of the light source and extending along the length direction of the vehicle lamp, a light-transmitting member disposed outside the vehicle lamp, a light homogenizing member disposed on the side of the light conductor close to the outside of the vehicle lamp, a light guide bracket on the side of the light conductor close to the inside of the vehicle lamp, and a reflective bracket disposed inside the vehicle lamp. Through the reflection, refraction, etc. of the light conductor on the light, the light can be respectively emitted to the light-transmitting member, the light homogenizing member, the light guide bracket, and the reflective bracket in different directions, so as to achieve the discrete effect of the large-area light-emitting surface of the light homogenizing member and the clear effect of the light-transmitting member through different optical paths. For the automobile including such a vehicle lamp provided by the present invention, since the vehicle lamp only uses a set of independent light sources, compared with the vehicle lamps in the prior art that use multiple sets of independent light sources to respectively achieve the clear effect and the discrete effect, the functional loss of the automobile is reduced, the cost is reduced, and when the area of the light-emitting surface of the light homogenizing member is relatively large, the vehicle lamp achieves the effect of layered light emission and uniform lighting.

[0055] To make the objectives, technical solutions and advantages of the present invention clearer, the following will further describe in detail the implementation modes of the present invention with reference to the accompanying drawings.

[0056] In the prior art, when achieving a large light-emitting area, a layered light pattern and uniform lighting for vehicle signal lights, multiple groups of light sources need to be set, resulting in high power consumption and high cost.

[0057] Embodiment 1

[0058] To address the above problems, the present invention provides a vehicle lamp. As shown in Figure 1 and Figure 2 , when the vehicle lamp is installed on a vehicle, the width direction of the vehicle lamp is parallel to the length direction X of the vehicle, the length direction of the vehicle lamp is parallel to the width direction Y of the vehicle, and the height direction of the vehicle lamp is parallel to the height direction Z of the vehicle. And the vehicle lamp has an inner side of the vehicle lamp ( Figure 1 the side facing into the paper in Figure 1 ) facing the inside of the vehicle and an outer side of the vehicle lamp (

[0059] the side facing out of the paper in Figures 3 - 6 ) facing the outside of the vehicle along its width direction; the vehicle lamp includes a light source 10 and a light guide assembly 20. Figure 3 As shown in Figure 3 , the light guide assembly 20 includes a light conductor 200 extending along the length direction of the vehicle lamp (as shown in Figure 5 and Figure 6 ), a light transmissive member 210, and a light homogenizing component 220. It should be noted that a connection structure for fixedly connecting to the inside of the vehicle lamp should also be provided on the light conductor 200. As shown in

[0060] As shown inFigures 3 - 4 As shown, an end face at one end of the light conductor 200 forms a first incident surface 2001, and the light-emitting end of the light source 10 is arranged facing the first incident surface 2001; as Figures 5 - 6 shown, the outer periphery of the light conductor 200 has a light guide tooth surface 2002 and a first emission surface 2004 along its circumferential direction. The light guide tooth surface 2002 is located on the side of the light conductor 200 close to the inside of the vehicle lamp, and in the cross-section of the light conductor 200, that is, Figure 2 in the sectional view perspective in the A-A direction in, the light guide tooth surface 2002 is straight, and light guide teeth 2003 are arranged on the light guide tooth surface (as Figure 12 shown); the first emission surface 2004 includes an arc surface, that is, in the cross-section of the light conductor 200, at least part of the first emission surface 2004 is an arc line; specifically, the cross-section of the light conductor 200 can be D-shaped, where the arc part is the first emission surface 2004, or it can be as Figure 5 and Figure 6 shown, the cross-section of the light conductor 200 can be close to circular, and has a protruding part on the side facing the inside of the vehicle lamp. The arc part and the protruding part of the close-to-circular shape that are along the width direction of the vehicle lamp are both the first emission surface 2004. It should be noted that the light conductor 200 can be set to have an arc-shaped extension part along its length direction as needed, and the corresponding light guide tooth surface 2002 is an arc surface along the length direction of the light conductor 200.

[0061] The light-transmitting member 210 is arranged on the outside of the vehicle lamp, and the side surface of the light-transmitting member 210 on the outside of the vehicle lamp is the second emission surface 2102, the side surface facing the inside of the vehicle lamp is the second incident surface 2101, and the first part 2004-a of the first emission surface is arranged opposite to the first part 2101-c of the second incident surface. The material of the light-transmitting member 210 should have excellent light-transmitting performance, a material with very little loss during the light propagation process. The light-transmitting member 210 can specifically be a transparent white inner optical lens; the light homogenizing member 220 is arranged on the side of the light conductor 200 close to the outside of the vehicle lamp, and the side surface of the light homogenizing member 220 facing the inside of the vehicle lamp is the third incident surface 2201, and the side surface facing the outside of the vehicle lamp is the third emission surface 2202; and at least part of the third incident surface 2201 is arranged opposite to the second part 2004-b of the first emission surface. The light homogenizing member 220 should have a light-transmitting function and at the same time have a discrete effect. The light homogenizing member 220 can specifically be a milky white discrete inner optical lens, and discrete particles are added therein to achieve uniform scattering of light.

[0062] Specifically, in this embodiment, the light conductor 200 conducts the light emitted by the light source 10 along the length direction of the vehicle headlight to the entire length direction of the vehicle headlight. The light guide teeth 2003 can cause the light to refract on the light guide tooth surface 2002. The light emitted from the first part 2004-a of the first exit surface can enter the first part 2101-c of the second entrance surface of the light transmissive member 210, and then exit through the second exit surface 2102 of the light transmissive member 210. Since the material of the light transmissive member 210 has excellent light transmissive performance, a clear effect can be achieved, so that the vehicle headlight can meet the regulatory requirements. The light emitted from the second part 2004-b of the first exit surface of the light conductor 200 can enter the third entrance surface 2201 of the light homogenizing member 220 and exit through the third exit surface 2202 after uniform scattering, achieving a uniform lighting effect when the light emitting area of the light homogenizing member 220 is large, that is, a discrete effect.

[0063] As Figure 5 shown, in an implementation manner of this embodiment, the light homogenizing member 220 is disposed on one side of the second entrance surface 2101 of the light transmissive member 210, and the third exit surface 2202 is disposed opposite to the second part 2101-d of the second entrance surface. This setting method can form at least two optical paths.

[0064] Specifically, as Figure 7 shown, the outer periphery of the light transmissive member 210 is provided with a mounting structure, including a mounting portion with a mounting hole connected to the light transmissive member 210. Through these mounting portions, the light transmissive member 210 can be fixedly connected to the outside of the vehicle headlight; as Figure 8 shown, the upper side of the light homogenizing member 220 is connected with a mounting structure, and through the mounting structure, the light homogenizing member 220 can be connected to other components of the vehicle headlight.

[0065] The first optical path is as Figure 9 shown, the light emitted by the light source 10 is refracted by the light guide teeth 2003 on the light guide tooth surface 2002 and shoots towards the first part 2004-a of the first exit surface, and can relatively enter the first part 2101-c of the second entrance surface and exit through the second exit surface 2102. And diffusion lines can be provided on the first part 2101-c of the second entrance surface, and the light can be uniformly diffused through the diffusion lines. The light transmissive member 210 can specifically be a transparent white inner lens to achieve a clear light distribution effect, so that the vehicle headlight can meet the regulatory requirements.

[0066] The second optical path is as Figure 10As shown, the light rays emitted by the light source 10 are refracted by the light guide teeth 2003 of the light guide tooth surface 2002 and shoot towards the second part 2004-b of the first exit surface, and can relatively enter the third entrance surface 2201, undergo uniform scattering within the light homogenizing member 220, and then relatively enter the second part 2101-d of the second entrance surface from the third exit surface 2202 and exit from the second exit surface 2102, achieving the uniform lighting effect of the light homogenizing member 220. The light homogenizing member 220 can specifically be an opalescent discrete internal light lens, and the uniform scattering of light rays can be achieved by adding discrete particles within the light homogenizing member 220.

[0067] As Figure 6 shown, in another specific implementation manner of this embodiment, the light transmissive member 210 and the light homogenizing member 220 are connected to each other and disposed outside the vehicle lamp. Among them, the light transmissive member 210 is on the lower side and the light homogenizing member 220 is on the upper side. Specifically, the light transmissive member 210 can be a transparent white internal light lens, and the light homogenizing member 220 can be an opalescent discrete internal light lens. This implementation manner can also form two optical paths. The first optical path includes that the light rays emitted by the light source 10 are refracted by the light guide teeth 2003 of the light guide tooth surface 2002 and shoot towards the first part 2004-a of the first exit surface of the light conductor 200, relatively enter the first part 2101-c of the second entrance surface and exit from the second exit surface 2102, and the clear effect is achieved through the propagation of light rays; the second optical path includes that the light rays emitted by the light source 10 are refracted by the light guide teeth 2003 of the light guide tooth surface 2002 and shoot towards the second part 2004-b of the first exit surface, relatively enter the third entrance surface 2201, undergo uniform scattering within the light homogenizing member 220, and then exit from the third exit surface 2202, and the discrete effect is achieved through the propagation of light rays. The light rays refracted by the light guide teeth 2003 of the light guide tooth surface 2002 can also shoot towards the reflective bracket 240, be reflected by the reflection surface 2401 and then exit from the second exit surface 2102 and the third exit surface 2202. This setting method is applicable to vehicle lamps with a relatively large light emitting surface in the height direction.

[0068] It should be noted that in this embodiment, the subsequent description mainly focuses on the above-mentioned previous implementation manner ( Figure 5 shown) to elaborate on this solution in detail.

[0069] In an implementation manner of this embodiment, as Figure 5As shown in the figure, the light guide assembly 20 further includes a light guide bracket 230 and a reflective bracket 240 that extend along the length direction of the vehicle headlamp; the light guide bracket 230 is disposed on the side of the light conductor 200 closer to the inner side of the vehicle headlamp, and the side of the light guide bracket 230 closer to the light conductor 200 is the fourth incident surface 2301, the side of the light guide bracket 230 away from the light conductor 200 is the fourth exit surface 2302, and the fourth incident surface 2301 is disposed opposite to the light guide tooth surface 2002; the reflective bracket 240 is disposed on the inner side of the vehicle headlamp, the side of the reflective bracket 240 facing the outer side of the vehicle headlamp is the reflective surface 2401, and the reflective surface 2401 of the reflective bracket 240 is respectively disposed opposite to the fourth exit surface 2302 and the third incident surface 2201.

[0070] This setting method will form a third path of light, such as Figure 11 As shown in the figure, the light emitted by the light source 10 is refracted by the light guide teeth 2003 of the light guide tooth surface 2002, enters from the fourth incident surface 2301 and exits from the fourth exit surface 2302, shoots towards the reflective surface 2401, and after being reflected by the reflective surface 2401, it can enter the third incident surface 2201 from multiple directions, scatter in the light homogenizing member 220 and then exit from the third exit surface 2202, further realizing the lighting effect of the light homogenizing member 220, and shooting towards the second part 2101-d of the second incident surface opposite thereto, and finally exiting from the second exit surface 2102. As Figure 15 As shown in the figure, it is the lighting effect achieved by the vehicle headlamp with the above setting method.

[0071] For Figure 6 Another specific implementation manner shown in the figure, the reflective bracket 240 is disposed on the inner side of the vehicle headlamp, the side of the reflective bracket 240 facing the outer side of the vehicle headlamp is the reflective surface 2401, and the reflective surface 2401 of the reflective bracket 240 is respectively disposed opposite to the third incident surface 2201 of the light homogenizing member 220 and the first part 2101-c of the second incident surface of the light transmissive member 210. The light emitted by the light source 10 can be refracted by the light guide teeth 2003 of the light guide tooth surface 2002 and then shoot towards the reflective surface 2401, and after being reflected, it can shoot towards the third incident surface 2201 and the first part 2101-c of the second incident surface, and exit from the third exit surface 2202 and the second exit surface 2102, realizing the clear and discrete effects.

[0072] Through the above setting method of combining the light transmissive member 210, the light homogenizing member 220, the light guide bracket 230 and the reflective bracket 240, only one set of light sources needs to be set, and the clear light distribution effect of the light transmissive member 210 and the discrete light distribution effect of the light homogenizing member 220 can be realized, so as to achieve the hierarchical lighting effect required in the vehicle headlamp styling design.

[0073] In one implementation manner of the present invention, diffusion patterns are provided on the first part 2101-c of the second incident surface and the reflective surface 2401 of the vehicle headlamp.

[0074] Specifically, in this embodiment, the shape of the diffusion pattern can be triangular, strip-shaped, grid-shaped, or other irregular shapes, etc., as long as it can satisfy the diffusion of light in multiple angles, change the reflection or refraction angle of the light, and make the light diverge from multiple angles.

[0075] In one embodiment of the present invention, the diffusion pattern 250 is a plurality of strip-shaped patterns arranged in an array (as shown in Figure 14 ), or a plurality of grid patterns (as shown in Figure 13 ), and the width of each strip-shaped pattern or grid pattern is 0.5 mm - 2 mm.

[0076] Specifically, in this embodiment, the plurality of strip-shaped patterns or grid patterns arranged in an array make the light evenly diffuse in multiple directions between the gaps of the patterns, can expand the light refraction and reflection areas of the light-transmitting member 210 and the reflective bracket 240, and can eliminate the light spot.

[0077] In one embodiment of the present invention, as shown in Figure 5 , along the height direction of the vehicle lamp, the light guide bracket 230 and the reflective bracket 240 are arranged on the lower side of the vehicle lamp, and the light homogenizing member 220 is arranged on the upper side of the light conductor 200; and the light guide bracket 230 and the reflective bracket 240 are arc-shaped structures protruding towards the inner side of the vehicle lamp.

[0078] Specifically, in this embodiment, the arc-shaped surface formed by the arc-shaped structure can make the light emission range angle cover multiple directions.

[0079] In one embodiment of the present invention, the materials of the light conductor 200, the light-transmitting member 210, the light homogenizing member 220, the light guide bracket 230, and the reflective bracket 240 of the vehicle lamp are made of polycarbonate materials; the height of the light-transmitting member 210 is 4 mm - 35 mm, and it has a laser-engraved pattern.

[0080] Specifically, in this embodiment, since the polycarbonate material has excellent light transmittance, good mechanical properties, flame retardancy, and high temperature resistance, it can be used as the preferred material for the light conductor 200, the light-transmitting member 210, the light homogenizing member 220, the light guide bracket 230, and the reflective bracket 240. Making a laser-engraved pattern on the surface of the light-transmitting member 210, performing black paint spraying and laser engraving treatment, can process various surface texture effects, and improve the appearance texture of the vehicle lamp.

[0081] In one embodiment of the present invention, the light source 10 of the vehicle lamp has two chips, which emit lights of different colors respectively.

[0082] Specifically, in this embodiment, two chips capable of emitting lights of different colors are provided inside the light source 10, specifically, they can be red and yellow LED chips or yellow and white LED chips, and single or multiple signal lights of different light colors can be lit according to requirements. For example, signal lights such as daytime running lights, front and rear position lights, brake lights, front and rear turn signals, etc. can be lit individually, or two of the above signal lights can be lit simultaneously through two light colors.

[0083] In one embodiment of the present invention, as Figure 2 shown, the vehicle lamp further includes a circuit board 30 and a radiator 40; the circuit board 30 is mounted on the radiator 40, and the light source 10 is mounted on the circuit board 30.

[0084] Specifically, in this embodiment, the light source 10 and other controllers are connected to the circuit board 30 to directly control the light color of the light source 10, etc. The radiator 40 can dissipate the heat generated by the long-term use of the vehicle lamp of the light source 10 to avoid the risk of high-temperature ablation.
