It should be noted that the following are only certain specific implementation methods of the present invention, which are only part of the embodiments of the present invention, wherein the specific and direct description of the relevant structures is only for the convenience of understanding the present invention, and each specific feature does not naturally and directly limit the scope of implementation of the present invention. The conventional selections and substitutions made by those skilled in the art under the guidance of the present invention shall be deemed to be within the scope of protection claimed by the present invention.

[0035] Embodiment 1:

[0036] like Figure 1-Figure 3 As shown, the utility model discloses a thick-walled component for weakening bright spots, including a thick-walled component body 1 in a two-step stepped shape, the front-to-back width of the upper step 11 is greater than the front-to-back width of the lower step 12, and the front side of the lower step is formed on the rear side of the upper step 11, and the thick-walled component body 1 is provided with an incident end 13 and an exit end 14, wherein the incident end 13 is located below the lower step 12, and the exit end 14 is located in front of the upper step 11, and in addition, the incident end 13 is provided with a focusing member 131, and in addition The thick-walled component body 1 is provided with a first reflecting portion 15, a second reflecting portion 16 and a third reflecting portion 17. Specifically, the first reflecting portion 15 is arranged on the rear side of the lower step 12, the second reflecting portion 16 is arranged on the front side of the lower step 12, and the third reflecting portion 17 is arranged on the rear side of the upper step 11; so that the light is converged from the incident end 13 by the focusing member 131 and incident on the thick-walled component body 1, and then reflected by the first reflecting portion 15, the second reflecting portion 16 and the third reflecting portion 17 in sequence, and finally emitted from the exit end 14.

[0037] Therefore, 1. the light cannot be directly emitted from the emission end 14 due to the limitation of the shape of the thick-walled part, so as to prevent the direct emission from causing obvious bright spots; 2. the light can be effectively converged under the action of the focusing member 131, so that the divergent light can be converged to enhance the emission brightness; 3. under the joint action of the first reflecting part 15, the second reflecting part 16 and the third reflecting part 17, the incident light is emitted after multiple reflections to weaken the bright spots.

[0038] Among them, the incident end 13 is arranged with multiple incident parts 132; correspondingly, the first reflecting part 15 is respectively provided with a first reflecting surface 151 corresponding to each incident part 132, and each first reflecting surface 151 is arranged along the arrangement direction of the incident part 132; so that the light incident from each incident part 132 is reflected by the corresponding first reflecting surface 151 and emitted to the second reflecting part 16, and the light incident from each incident part 132 is only partially reflected under the action of the corresponding first reflecting surface 151. After reflection, the light from different incident parts 132 is combined and emitted to the second reflecting part 16, so that the combined light is composed of multiple partitions with similar brightness, and the visual effect of gradually decreasing brightness is reduced and the bright spots are weakened.

[0039] Furthermore, each of the first reflecting surfaces 151 includes a multi-faceted split surface 1511, and the split surfaces 1511 corresponding to each of the first reflecting surfaces 151 are coplanarly arranged, and the split surfaces 1511 corresponding to each of the first reflecting surfaces 151 are arranged at intervals, and the split surfaces 1511 corresponding to each of the first reflecting surfaces 151 and the split surfaces 1511 corresponding to other first reflecting surfaces 151 are alternately arranged along the arrangement direction of the split surfaces 151, so that the first reflecting surfaces 151 are further separated, so that each first reflecting surface 151 uses a discontinuous multi-faceted split surface 1511 to intercept the corresponding continuous light, and multiple segments of light from different first reflecting surfaces 151 are alternated, so that the combined light is composed of more partitions with similar brightness and small range, which further reduces the visual effect of gradually decreasing brightness and weakens the bright spots.

[0040] Specifically, in this embodiment, the number of incident portions 132 and the number of first reflection surfaces 151 corresponding to the incident end 13 are both two, and the number of split surfaces 1511 corresponding to the first reflection surface 151 is three.

[0041] In addition, the second reflective portion 16 in this embodiment is arranged with a plurality of second reflective strips 161, and the third reflective portion 17 is arranged with a plurality of third reflective strips 171 along the length direction of the thick-walled member body 1; wherein the number of the second reflective strips 161 and the third reflective strips 171 is greater than the number of the incident portion 132; specifically, each of the second reflective strips 161 is provided with a second reflective surface 1611 and a second connecting surface 1612, and the second connecting surface 1612 is used to connect the corresponding second reflective surface 1611 with the second reflective surface 1611 on the adjacent second reflective strip 161; The third reflection strip 171 is provided with a third reflection surface 1711 and a third connecting surface 1712. The third connecting surface 1712 is used to connect the corresponding third reflection surface 1711 with the third reflection surface 1711 on the adjacent third reflection strip 171, so that the combined light from the first reflection portion 15 is further disturbed in continuity by the action of a large number of second reflection strips 161, thereby further weakening the bright spot. Similarly, the combined light from the second reflection portion 16 is further disturbed in continuity by the action of a large number of third reflection strips 171, thereby further weakening the bright spot.

[0042] Preferably, the number of the incident ends 13 in this embodiment is multiple, and each of the incident ends 13 is arranged along the length direction of the thick-walled part; the arrangement direction of the incident ends 13 and the arrangement direction of the incident portion 132 are non-parallel, so that multi-region light is injected through more incident ends 13 to further differentiate the continuity of the light, and the non-parallel arrangement can make the diagonals of the incident ends 13 connected while meeting a specific exit area, so as to reduce and eliminate the distance between two adjacent incident ends 13, so that the intensity difference of the light injected into the thick-walled part body 1 is minimized, so as to make the light uniformity better.

[0043] Specifically, the number of incident ends 13 in this embodiment is 9.

[0044] Preferably, the arrangement direction of the incident end 13 and the first reflecting surface 151 are arranged non-parallel to adapt to the above arrangement.

[0045] In addition, the output end 14 in this embodiment is provided with a plurality of output portions 141 arranged in a matrix, and each of the output portions 141 is provided with a curved output surface 142; the number of the output portions 141 is greater than the number of the incident portions 132, so that the light is further refracted through the curved output surfaces 142 on a large number of the output portions 141, so as to further disperse the light and weaken the bright spots.

[0046] Preferably, the focusing element 131 in this embodiment includes incident planes 1311 corresponding to the number of incident portions 132 and a focusing arc surface 1312 located on the periphery of the incident plane 1311 and convex in shape, so that light is incident from the corresponding incident plane 1311, and the incident light is partially incident on the focusing arc surface 1312 in a divergent manner, so that more light is reflected toward the first reflecting portion 15 under the reflection of the focusing arc surface 1312.

[0047] Embodiment 2:

[0048] like Figure 4-Figure 7 As shown, the utility model discloses an LED vehicle lamp, comprising a housing 2, a circuit board 3 and the thick-walled member for weakening bright spots as described in the first embodiment.

[0049] The circuit board 3 and the thick-walled member body 1 are both mounted on the housing 2, and the circuit board 3 is located below the thick-walled member body 1. Correspondingly, the circuit board 3 is provided with LED lamp beads 31 corresponding to each incident portion 132, and each LED lamp bead 31 faces the corresponding incident portion 132. Therefore, a plurality of LED lamp beads 31 emit light and are incident on the corresponding incident portion 132, and under the action of the focusing member 131, the light is emitted toward the first reflecting portion 15 in the form of regional focused light. The light of each LED lamp bead 31 is partially reflected under the action of the corresponding split surface 1511, and different incident portions of the same incident end 13 are reflected by the light of the split surface 1511. The light rays of the emitting portion 132 are alternately combined, and then the alternately combined light rays of different incident ends 13 are arranged and combined to form a light group and emitted to the second reflecting portion 16. Under the action of a large number of discontinuous second reflecting surfaces 1611 of the second reflecting portion 16, the continuity of the light rays is interrupted again, and the light rays are emitted to the third reflecting portion 17. Under the action of a large number of discontinuous third reflecting surfaces 1711 of the third reflecting portion 17, the continuity of the light rays is interrupted again, and the light rays are emitted to the emitting end 14, and are preferably refracted by the arcuate emitting surfaces 142 on the large number of emitting portions 141, so that the bright spots of the emitted light rays are effectively weakened and the visual effect is improved.

[0050] In addition, the shell 2 includes an upper shell 21 and a lower shell 22. The thick-walled component body 1 is installed under the clamping of the upper shell 21 and the lower shell 22, and the circuit board 3 is arranged on the lower side of the lower shell 22. In addition, the lower shell 22 includes a spacer 221, and the spacer 221 is vertically penetrated with a spacer cavity 222 corresponding to each incident end 13. Each LED lamp bead 31 corresponding to each incident end 13 faces upward and toward the corresponding spacer cavity 222, and a part of the structure of the incident end 13 extends into the spacer cavity 222, so that the light emitted by the LED lamp bead 31 enters the corresponding spacer cavity 222 and then enters the incident end 13, so that the LED lamp beads 31 corresponding to different incident ends 13 are separated by the spacer cavity 222 to prevent the LED lamp beads 31 from mutually scattering light, especially the LED lamp beads 31 used at different incident ends 13 are of different colors.

[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
