[0002] In order to meet the OEM's requirements for uniform lighting of lamps, conventional concentrator-type thick-walled parts usually use a solution of densely arranging LEDs to ensure that there is no dark area between LEDs. This solution will increase product costs. At the same time, if the internal space of the lamp is small and the PCB area is small, the solution with a large number of LEDs will cause the lamp to generate heat. In short, the traditional solution cannot achieve the low cost and high efficiency requirements required by automobile manufacturers.

[0003] In view of this, it is necessary to design a thick-walled structure that can realize uniform light emission at large intervals of light sources, so as to overcome the above-mentioned defects. Utility Model Content

[0037] See also Figure 1 and Figure 6 A specific implementation of the utility model is a thick-walled component structure that realizes uniform light emission of a light source with a large spacing, and is used to receive incident light emitted by a light-emitting unit 3, including a thick-walled component body 1 and a focusing component 2, the thick-walled component body 1 is connected to the focusing component 2, and the surface of the thick-walled component body 1 is recessed toward the inside of the thick-walled component body 1 corresponding to the position of the focusing component 2 to form a recessed component 12, the side walls of the recessed component 12 are suitable for diffusing the incident light to the surrounding side walls of the thick-walled component body 1, and collimating the diffused incident light through the surrounding side walls of the thick-walled component body 1 and emitting it in the same direction, thereby effectively increasing the lateral distance of the light.

[0038] See also Figures 1 to 5 Specifically, the recessed component 12 formed inside the thick-walled component body 1 is a pyramid-shaped recessed component 12, and the normal of the side wall of the recessed component 12 is set at an acute angle to the incident light after collimation by the focusing component 2. The left and right inclined surfaces of the recessed component 12 are suitable for reflecting the incident light to the left and right walls of the thick-walled component body 1 respectively, and after being reflected by the left and right walls of the thick-walled component body, the incident light is collimated and corrected to be emitted in the same direction. The rear inclined surface of the recessed component 12 is suitable for reflecting the incident light to the left wall of the thick-walled component body 1, and after being reflected by the left wall, it is emitted to the right wall of the thick-walled component body 1, and after being reflected by the right wall of the thick-walled component body 1, it is collimated to be emitted in the same direction; the front inclined surface of the recessed component 12 is suitable for reflecting the incident light and collimating it to be emitted in the same direction. Therefore, when the incident light is directed to the side wall of the recessed component 12, the incident light is reflected by the side wall of the recessed component 12, and the reflected incident light is directed to the inner wall of the thick-walled component body 1, and then is reflected by the inner wall of the thick-walled component body 1 and collimated before being emitted. It should be noted that by adjusting the inclination angle of the side wall of the recessed component 12, the light emitting width of the light emitting unit 3 can be effectively controlled.

[0039] See also Figures 6 to 9More specifically, the thick-walled component body 1 includes a plurality of thick-walled structural units 11, which are arranged horizontally, and can also be arranged according to the inclined shape of the automobile corner lamp. It should be noted that since the top view of the thick-walled structural unit 11 is a triangular structure, the overlapping parts are formed into one by overlapping the tips of the plurality of triangular thick-walled structural units 11, so that the plurality of thick-walled structural units 11 are arranged in sequence to form the entire thick-walled component body 1.

[0040] In addition, the spacing between the plurality of thick-walled structural units 11 can be flexibly adjusted according to actual needs. During the adjustment, the position of the recessed components 12 provided in the thick-walled member body 1 can be adjusted to change the distance between the recessed components 12 of the connected thick-walled structural units 11, thereby achieving uniform lighting of a large spacing of various shapes.

[0041] See also Fig.10 and Fig.11 In order to better receive the incident light emitted by the light-emitting unit 3, the light-emitting unit 3 is arranged at the light-entering part of the focusing component 2. When the light-emitting unit 3 emits light, the incident light emitted by the light-emitting unit 3 can be received by the focusing component 2 as much as possible, and then the incident light passes through the focusing component 2 and enters the thick-walled component body 1. Then the incident light enters therein and contacts the side wall of the recessed component 12 and is reflected. The incident light after reflection irradiates the side wall of the thick-walled component body, and then passes through the side wall of the thick-walled component body to collimate the incident light and emit it. And the light-emitting unit 3 can choose to use a single-core LED light source or a multi-core LED light source of multiple colors. And this structural setting can effectively reduce the number of LEDs and reduce the production cost of lamps.

[0042] The thick-walled member body 1 can be made of PC material or PMMA material. A pattern structure is provided on the light-emitting surface of the thick-walled member body 1, and the pattern structure can be in the shape of corn kernels, stripes, or the like.
