Referring to fig. 1 and 2, an embodiment of the present application provides an automotive position light 10 (hereinafter referred to as position light 10). The position light 10 includes a housing 110 and a transparent cover 120 coupled to the housing 110. Referring to fig. 3 to 6, a lamp cavity 130 is defined between the transparent lamp cover 120 and the housing 110. A first light emitting assembly 200 is disposed within the lamp chamber 130. The first light emitting assembly 200 includes: the first light source 220 is disposed on the first PCB 210, the first light source 220 (e.g., LED light source), the hollow projector 230, and the first thick-wall light guide 240. Referring to fig. 7 and 8, the first thick-walled light guide 240 includes integrally formed first, second and first red transparent blocks 241, 242 and 243. The cavity 231 of the hollow projector 230 has opposite light exit and entrance cavity walls 232, 233, and the hollow projector 230 has a light exit face 234 opposite the entrance cavity wall 233. The light-emitting cavity wall 232, the light-entering cavity wall 233, the light-emitting surface 234, the first colorless transparent block 241, the second colorless transparent block 242, the first red transparent block 243, and the transparent globe 120 are sequentially arranged on a propagation path of light emitted from the first light source 220.

In the position lamp 10, the light-emitting cavity wall 232, the light-entering cavity wall 233, the light-emitting surface 234, the first colorless transparent block 241, the second colorless transparent block 242, the first red transparent block 243, and the transparent cover 120 are sequentially arranged on the propagation path of the light emitted from the first light source 220, so that the light emitted from the first light source 220 is emitted through the light-emitting cavity wall 232, then emitted through the light-entering cavity wall 233, and then emitted through the light-emitting surface 234, and then sequentially passes through the first colorless transparent block 241, the second colorless transparent block 242, the first red transparent block 243, and the transparent cover 120, and then emitted. In this way, during the propagation process, the light emitted by the first light source 220 is first collimated and diffused by the light-emitting cavity wall 232, the light-entering cavity wall 233 and the light-emitting surface 234, and then further uniformly diffused by the light-incident surface 240a (i.e. the surface of the first non-color transparent block 241 facing away from the first red transparent block 243) and the light-emitting surface 240b (i.e. the surface of the first red transparent block 243 facing away from the first non-color transparent block 241) of the first thick-wall light guide 240, so that the light emitted by the first light source 220 is more uniformly diffused after being emitted by the transparent lampshade 120, thereby achieving the effect of uniformly lighting the position lamp 10 and the requirement of high brightness of light distribution, and reducing the particle feeling and the cavity feeling. Moreover, when the light emitted by the first light source 220 passes through the first thick-wall light guide 240, the light passes through the first non-colored transparent block 241 and the second non-colored transparent block 242 and then passes through the first red transparent block 243, so that the light transmittance of the first thick-wall light guide 240 can be improved compared with that of the solid single-color thick-wall light guide in the prior art, and further, the power of the first light source 220 can be reduced, the overall power consumption and cost of the position lamp 10 can be reduced, and the thermal performance can be improved on the basis of meeting the light distribution brightness requirement of the position lamp 10. Wherein, the hollow projector 230 is internally provided with a cavity 231 so as to play a role in weight reduction. The light from the first light source 220 exits the first red transparent block 243 of the first thick-walled light guide 240 so that the position light 10 still meets the red appearance requirements when lit.

In an embodiment, the first non-colored transparent block 241, the second non-colored transparent block 242, and the first red transparent block 243 are integrally formed by a three-color injection molding process.

A second recess 2421 is provided on a side of the second transparent block 242 facing away from the bottom of the first recess 2431. The first non-colored transparent block 241 includes: the colorless body portion 2411 and the colorless protrusion 2412 are connected, the colorless protrusion 2412 is disposed within the second cavity 2421, and the colorless body portion 2411 is disposed outside the second cavity 2421.

Since the second colorless transparent block 242 is disposed in the first cavity 2431 and the colorless protrusion 2412 is disposed in the second cavity 2421, the first red transparent block 243 is made to cover the second colorless transparent block 242 and the first colorless transparent block 241, so that the light emitted by the first light source 220 is ensured to be emitted from the first red transparent block 243 after passing through the two colorless transparent blocks (the first colorless transparent block 241 and the first colorless transparent block 242), and the red appearance effect of the position lamp 10 can be ensured when the light emitted by the first light source 210 passes through the first thick-wall light guide 240.

Since the colorless body portion 2411 is located outside the second cavity 2421, it is convenient to achieve connection of the first thick-walled light guide 240 with the hollow projector 230 by connection of the colorless body portion 2411 with the hollow projector 230. Thus, the first thick-walled light guide 240 can be installed in the housing 110 at the same time as the hollow projector 230 is connected to the housing 110.

The second light source 320 is disposed on the second PCB 310, and the second thick-wall light guide 340 includes a third colorless transparent block 341 and a second red transparent block 342 that are integrally formed. The thick-wall projector 330, the third colorless transparent block 341, the second red transparent block 342, and the transparent cover 120 are sequentially arranged on a propagation path of the light emitted from the second light source 320.

Because the thick-wall projector 330, the third colorless transparent block 341, the second red transparent block 342 and the transparent lamp cover 120 are sequentially arranged on the propagation path of the light emitted by the second light source 320, the light emitted by the second light source 320 is collimated and diffused by the light incident surface 330a and the light emergent surface 330b of the thick-wall projector 330, and then further uniformly diffused by the light incident surface 340a (i.e., the surface of the third colorless transparent block 341 away from the second red transparent block 342) and the light emergent surface 340b (i.e., the surface of the second red transparent block 342 away from the third colorless transparent block 341) of the second thick-wall light guide 340, so that the light emitted by the second light source 320 is more uniformly diffused after being emitted by the transparent lamp cover 120, thereby achieving the effect of uniformly lighting the position lamp 10 and the requirement of high brightness of light distribution, and reducing the particle feeling and the cavity feeling. Moreover, when the light emitted by the second light source 320 passes through the second thick-wall light guide 340, the light passes through the third colorless transparent block 341 and then passes through the second red transparent block 342, so that the power of the second light source 320 can be reduced, the overall power consumption and cost of the position lamp 10 can be reduced, and the thermal performance can be improved on the basis of meeting the light distribution brightness requirement of the position lamp 10. And the position light 10 still meets the red appearance requirement when lit.
