[0026] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] Embodiment 1:

[0028] like Figures 1-2 A dual-light structure with uniform illumination is shown, comprising a thick-walled component and two LED light sources, wherein the LED light sources are divided into a first LED light source 10 and a second LED light source 14, wherein the first LED light source 10 and the second LED light source 14 share a PCB board, or the first LED light source 10 and the second LED light source 14 may independently use the PCB board, and the thick-walled component has two light channels, each light channel corresponding to an LED light source with a different function, and of course the functions of the two LED light sources may also be the same, and each LED light source emits light into the corresponding light channel to form a first light path and a second light path.

[0029] like Figure 1 As shown, the thick-walled member includes a first thick-walled member and a second thick-walled member, the first thick-walled member and the second thick-walled member are arranged side by side, and the first thick-walled member and the second thick-walled member are an integrally formed structure.

The surface of the light-emitting surface is provided with a pattern, and the pattern is a leather pattern, a vertical pattern or a corn grain pattern. The light can be scattered on the ring pattern, which effectively prevents the formation of bright spots, beautifies the appearance, and has a uniform lighting effect. The upper ends of the first thick-walled member and the second thick-walled member are provided with a concentrator, and the corresponding LED light source is placed at the focus of the concentrator, so that the light is more uniform, brighter, and has a better lighting effect, achieving the purpose of efficient and collimated light output;

[0031] A portion of the light emitted by the LED light source corresponding to the first optical path passes through the concentrator of the first thick-walled member to the reflective surface, and finally is emitted from the light-emitting surface of the second thick-walled member; another portion of the light passes through the concentrator of the first thick-walled member to the reflective surface, and finally is emitted from the light-emitting surface of the first thick-walled member;

[0032] The light emitted by the LED light source corresponding to the second light path passes through the concentrator of the second thick-walled member to the reflecting surface, and finally is emitted from the light emitting surface of the second thick-walled member, thereby expanding the illumination area.

[0033] Specifically, the first thick-walled member includes a first thick-walled member body, the left side of the first thick-walled member body is a reflecting surface, the lower right end of the first thick-walled member body is a light-emitting surface 7 of the first light path, the reflecting surface includes a first reflecting surface 2 of the first light path and a second reflecting surface 3 of the first light path, and a first light path condenser 1 is provided at the upper end of the first thick-walled member body, and the first LED light source 10 is directly opposite to the first light path condenser 1;

[0034] A portion of the light emitted by the LED light source corresponding to the first optical path passes through the first optical path concentrator 1 to be reflected by the first reflection surface 2 of the first optical path, and finally emerges from the light emitting surface 6, and another portion of the light emitted by the LED light source corresponding to the first optical path passes through the first optical path concentrator 1 to be reflected by the second reflection surface 3 of the first optical path, and finally emerges from the light emitting surface 7 of the first optical path of the second thick-walled part.

[0036] In addition, the first light path concentrator 1 and the second light path concentrator 4 are both circular concentrators or special-shaped concentrators, and the first reflection surface 2 of the first light path, the second reflection surface 3 of the first light path, and the reflection surface 5 of the second light path form a certain angle with the normal of the concentrator, so that the light can be emitted perpendicular to the normal of the concentrator after reflection, and the reflection surface angle can be changed according to the shape requirements of the lamp.

[0037] Among them, the first reflection surface 2 of the first light path is parallel to the reflection surface 5 of the second light path, the light exit surface 7 of the first light path is parallel to the light exit surface 6, and the light exit surface 7 and the light exit surface 6 of the first light path are parallel to the normal of the concentrator.

[0038] The upper end point of the light emitting surface 6 is lower than the upper end point of the first reflecting surface 2 of the first light path, and the lower end point of the light emitting surface 6 is higher than the upper end point of the second reflecting surface 3 of the first light path.

[0039] The ray path is as follows:

[0040] First light path 8: The first light path of the first channel is emitted from the first LED light source 10, a part of the light passes through the first light path concentrator 1 to the first reflection surface 2 of the first light path, and finally emitted from the light emitting surface 6;

[0041] Another part of the light passes through the first light path concentrator 1 to be reflected by the second reflection surface 3 of the first light path, and finally is emitted from the light exit surface 7 of the first light path.

[0042] Second optical path 9: The second channel second optical path is emitted from the second LED light source 14, passes through the second optical path condenser 4 to be reflected by the reflection surface 5 of the second optical path, and finally emitted from the light emitting surface 6. The light of the first optical path surrounds the light of the second optical path, achieving the effect of nesting multiple functions.

[0045] The LED light source corresponding to the reflective surface 11 replacing the second light path is located above the light emitting surface 7 of the first light path.

[0046] In addition, the first LED light source 10 and the second LED light source 14 use independent PCB boards.

[0047] The ray path is as follows:

[0048] Replace the first light path 12: the first light path of the first channel is emitted from the first LED light source 10, a part of the light passes through the first light path concentrator 1 to the first reflection surface 2 of the first light path and finally emits from the light exit surface 6 of the first light;

[0049] Another part of the light passes through the first light path concentrator 1 to be reflected by the second reflection surface 3 of the first light path, and finally is emitted from the light exit surface 7 of the first light path.

[0050] Replace the second optical path 13: The second optical path of the second channel is emitted from the first LED light source 10 and is emitted through the reflecting surface 11 of the second optical path of the reflector module.

[0051] In summary: two lamp functions are nested in one thick-walled part, which reduces the difficulty of installing thick-walled parts in lamps, improves the aesthetics and uniformity of lamps, reduces the area of ​​PCB boards, and only one PCB board is needed to realize multiple functions, ensure heat dissipation, reduce lamp space, save the development cost of the whole vehicle, and shorten the research and development cycle of lamps.
