[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, a high-heat-dissipation LED taillight assembly for automobiles includes a taillight body, which comprises a first lamp body 1 and a second lamp body 2. The first lamp body 1 is located on one side of the second lamp body 2 and has an arc-shaped structure. The first lamp body 1 includes a first front mounting plate 3 and a first rear mounting base 4. A first LED lamp assembly 5 is disposed between the first front mounting plate 3 and the first rear mounting base 4. The second lamp body 2 includes a second front mounting plate 6 and a second rear mounting base 7. A second LED lamp assembly 8 is disposed between the second front mounting plate 6 and the second rear mounting base 7. The first LED lamp assembly 5 is provided with a first light-emitting area 9, a second light-emitting area 10, a third light-emitting area 11, and a fourth light-emitting area 12. The second LED lamp assembly 8 is provided with a fifth light-emitting area 13, a sixth light-emitting area 14, a seventh light-emitting area 15, and an eighth light-emitting area 16. The interior of the first light-emitting area 9, the second light-emitting area 10, the third light-emitting area 11, the fifth light-emitting area 13, the sixth light-emitting area 14, and the seventh light-emitting area 15 is divided into several independent and evenly distributed independent cavities according to the number of LEDs.

[0026] Furthermore, the second light-emitting area 10 is located between the first light-emitting area 9 and the third light-emitting area 11, the fourth light-emitting area 12 is located on one side of the first LED light group 5, and the third light-emitting area 11 is arranged in a stepped shape.

[0027] In this embodiment, the stepped distribution of the third light-emitting area 11 not only optimizes the light distribution but also enhances the three-dimensional visual effect of the taillights. Simultaneously, this design also aids in heat dissipation, as the stepped structure increases the heat dissipation area, allowing the heat generated by the LED light assembly during operation to be dissipated more effectively. The fourth light-emitting area 12 is located on one side of the first LED light assembly 5. This layout makes the overall shape of the taillights more complete and provides additional lighting or warning functions. The independent cavity design within all light-emitting areas not only ensures stable operation of the LEDs but also avoids heat concentration, further improving heat dissipation efficiency.

[0028] Furthermore, the first LED light group 5 and the second LED light group 8 are respectively fixedly mounted on the first front mounting plate 3 and the second front mounting plate 6 by bolts.

[0029] In this embodiment, the first LED light group 5 and the second LED light group 8 are fixedly installed by bolts, which not only ensures the stability of the light group, but also facilitates later maintenance and replacement.

[0030] Furthermore, the first light-emitting area 9 is located above the first LED light group 5, and a first lamp bead plate 17 is provided in the first light-emitting area 9. The first LED light group 5 is provided with a first mounting groove for mounting the first lamp bead plate 17, and the first lamp bead plate 17 is fixedly installed in the first mounting groove by a limiting block.

[0031] Furthermore, a second LED bead board 18 is fixedly installed on the back of the second light-emitting area 10, the third light-emitting area 11 is located below the first LED light group 5, and a plurality of third LED bead boards 19 are fixedly installed on the back of each step of the third light-emitting area 11, and a fourth LED bead board 20 is fixedly installed on the back of the fourth light-emitting area 12.

[0032] In this embodiment, the first LED bead plate 17 is installed in the first light-emitting area 9 and fixed in the first mounting groove by a limiting block. This design not only ensures the stability of the LED beads but also helps to distribute light evenly. The second LED bead plate 18 on the back of the second light-emitting area 10 and several third LED bead plates 19 installed on the back of each step of the third light-emitting area 11 together constitute the main lighting part of the taillight. This not only enhances the brightness of the taillight but also achieves multi-layered light distribution through the stepped design, enhancing the three-dimensionality and visual effect of the taillight.

[0033] Furthermore, the first LED light group 5 is configured with a uniformly distributed semi-circular arc structure at the positions where the first LED bead plate 17 and the second LED bead plate 18 are installed.

[0034] Furthermore, the fifth light-emitting area 13, the sixth light-emitting area 14, the seventh light-emitting area 15, and the eighth light-emitting area 16 are arranged from top to bottom on the second LED light group 8. The fifth light-emitting area 13 is fixedly mounted with a fifth LED bead plate 21 on its back, the sixth light-emitting area 14 is fixedly mounted with a sixth LED bead plate 22 on its back, the seventh light-emitting area 15 is fixedly mounted with a seventh LED bead plate 23 on its back, and the eighth light-emitting area 16 is fixedly mounted with an eighth LED bead plate 24 on its back.

[0035] In this embodiment, the fifth light-emitting area 13, the sixth light-emitting area 14, the seventh light-emitting area 15, and the eighth light-emitting area 16 are arranged from top to bottom on the second LED light group 8. This arrangement not only creates distinct layers but also achieves a diversified distribution of light through the fifth LED bead plate 21, the sixth LED bead plate 22, the seventh LED bead plate 23, and the eighth LED bead plate 24 fixed to their respective backs, thereby enhancing the recognizability and aesthetics of the taillights.

[0036] Furthermore, the second LED light group 8 has evenly distributed semi-circular arc structures at the positions where the fifth LED bead plate 21, the sixth LED bead plate 22, and the seventh LED bead plate 23 are installed.

[0037] Furthermore, a ninth light-emitting area 25 is provided below the seventh light-emitting area 15. The ninth light-emitting area 25 is located on one side of the eighth light-emitting area 16, and one side of the seventh lamp bead plate 23 is located within the ninth light-emitting area 25.

[0038] In this embodiment, the layout design of the seventh light-emitting area 15 and the ninth light-emitting area 25 is ingenious. It not only makes full use of the space inside the taillight, but also further enriches the lighting effect of the taillight by combining the seventh lamp bead plate 23 and the ninth light-emitting area 25, making the overall design of the taillight more in line with the aesthetic trend of modern automobiles.

[0039] Furthermore, a first external lamp plate 26 is fixedly installed on the outer side of the first front mounting plate 3, and a second external lamp plate 27 is fixedly installed on the outer side of the second front mounting plate 6.

[0040] In this embodiment, the first external lamp panel 26 and the second external lamp panel 27 are made of high light transmittance material to ensure that the light can be transmitted evenly and brightly.

[0041] The working principle of this utility model is as follows:

[0042] This invention solves the problem of poor heat dissipation in existing LED taillights by designing a highly efficient heat dissipation structure. Specifically, the high-heat-dissipation LED taillight of this invention adopts a design of multiple independent and evenly distributed cavities. These cavities not only optimize the layout of the LED taillights but also increase the heat dissipation area, allowing heat to be dissipated more effectively. Furthermore, this invention further improves heat dissipation efficiency by rationally setting the position and structure of the LED chip plates. For example, both the first and second LED taillights have evenly distributed semi-circular arc structures at the locations where the LED chip plates are installed. This design not only facilitates uniform light distribution but also increases the heat dissipation area and improves the heat dissipation effect. Simultaneously, corresponding LED chip plates are fixedly installed on the back of each light-emitting area, and through a reasonable layout and installation method, it is ensured that heat can be dissipated in a timely and effective manner through the heat dissipation structure, thereby avoiding the problem of excessively high LED taillight temperatures affecting luminous efficiency and lifespan.
