Detailed Implementation

[0024] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0025] Please refer to Figures 1 to 3 , Figure 1 This is a front view of a car taillight with good light guiding properties according to an embodiment of this utility model; Figure 2 This is a rear view of a car taillight with good light guiding properties according to an embodiment of this utility model; Figure 3 This is a schematic diagram of the lampshade according to an embodiment of the present utility model.

[0026] As shown in the figure, a car taillight with good light guiding properties includes: a lamp housing 10, wherein a turn signal cavity 11, a side marker light cavity 12, a brake light cavity 13, and a fog light cavity 14 are arranged laterally in sequence on the lamp housing 10, and a recessed groove is provided on the front edge of the lamp housing 10; a dual-level reflector strip 20 is embedded in the recessed groove, the dual-level reflector strip 20 includes an inner reflector ring and an outer reflector ring, the included angle between the inner reflector ring and the outer reflector ring is 120°-150°; and the taillight is secured by screws. A lamp cover plate 30 is fixed to the rear side of the lamp cup assembly housing 10, and a wire harness connector 31 is provided in the center of the lamp cover plate 30; a lamp cover 40 is sealed and fixed to the front side of the lamp cup assembly housing 10, and the lamp cover 40 has a first lamp cover part 41 corresponding to the turn signal cavity 11, a second lamp cover part 42 corresponding to the parking light cavity 12 and the brake light cavity 13, and a third lamp cover part 43 corresponding to the fog light cavity 14. The inner sides of the first lamp cover part 41, the second lamp cover part 42, and the third lamp cover part 43 have different light guiding surfaces.

[0027] In one embodiment of this utility model, the lamp housing 10 integrates four lamp cavities: a turn signal cavity 11, a parking light cavity 12, a brake light cavity 13, and a fog light cavity 14. These cavities can be used to install turn signals, parking lights, brake lights, and fog lights, respectively. Of course, in other embodiments, they can be replaced with other functional lights. The rear end of the lamp housing 10 is fixed to the lamp cover plate 30 with screws to form a rear seal, protecting the lamp source assembly. At the same time, the wiring harness connector 31 is used to complete the wiring harness connection.

[0028] The front side of the lamp housing 10 has a concave groove surrounding four lamp cavities. This groove is used to embed a double-stage reflective band 20, which consists of an inner reflective ring and an outer reflective ring, forming two relatively bent reflective rings. This allows for secondary reflection, increasing the front emission angle and light emission, thus improving the lighting and warning range. Preferably, the included angle between the two rings can be set to 120°-150° for good reflection and light emission; chrome plating can be used.

[0029] Furthermore, both the inner and outer reflective rings have multiple arc-shaped protrusions on their surfaces to increase the reflection angle.

[0030] The lampshade 40 is made of transparent PC material and is installed at the front end of the lamp holder assembly housing 10, serving both protective and light-guiding functions. It is divided into a first lampshade section 41, a second lampshade section 42, and a third lampshade section 43, each with a different light-guiding surface on its inner surface to correspond to different light source designs, thereby achieving high visibility.

[0031] Preferably, the first lampshade portion 41 has a square light guide portion at its center. The square light guide portion is composed of multiple square light guide units with arc protrusions, which serve as a turning indication function and have a simple structure.

[0032] The surface of the second lampshade 42 is composed of multiple vertically arranged arc-shaped light guide ridges, which serve as a rear brake width indicator.

[0033] The center of the third lampshade section 43 is a rectangular light guide section, which is composed of multiple square light guide units with arc protrusions. A reflective lattice is arranged around the outside of the rectangular light guide section. The reflective lattice enhances reflection and improves warning in foggy conditions.

[0034] In addition, a mounting bracket 50 is provided on the upper side of the lamp cup assembly housing 10 for easy assembly.

[0035] In summary, this utility model completes the lighting area arrangement by sequentially arranging the turn signal cavity 11, the parking light cavity 12, the brake light cavity 13, and the fog light cavity 14. At the same time, the outer double-level reflective strip 20 enhances light reflection, and the front lamp cover is provided with light guiding surfaces of different structures to improve light guiding performance and enhance the warning effect.

[0036] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
