Description

Technical Field

[0001] This utility model relates to the field of vehicle light heat dissipation technology, and in particular to an integrated heat dissipation trim structure. Background Technology

[0002] Currently, traffic lights, as a crucial component in existing lighting designs, are seeing a surge in innovative designs. However, cost and increasingly limited space in lighting fixtures pose significant challenges to traditional optical solutions. Existing traffic lights typically consist of an outer lampshade, an inner lampshade, a decorative ring, and LED modules. To ensure heat dissipation, a heat sink structure is often added. Once all these components are assembled, the space becomes quite cramped, leaving little internal space and resulting in poor heat dissipation. Furthermore, installing so many parts in a confined space is difficult and costly. Additionally, cold spots can easily appear in areas of the outer lampshade far from the LED modules, causing condensation and affecting the final lighting effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated heat dissipation ring structure that can combine the heat dissipation structure with the ring in a limited space, reducing the number of parts while ensuring heat dissipation performance.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] An integrated heat dissipation decorative ring structure includes an inner lampshade and an outer lampshade arranged inside and outside. An LED module is provided on the back side of the inner lampshade, and a heat dissipation decorative ring is provided between the outer lampshade and the inner lampshade.

[0006] The heat dissipation ring includes a heat sink body disposed on the back of the LED module, multiple heat sink connecting ribs connected to the heat sink body and located on the side of the inner lamp cover, a connecting plate connected to the multiple heat sink connecting ribs and located on the front side of the inner lamp cover, and multiple heat dissipation fins disposed on the connecting plate and bent toward the outer lamp cover.

[0007] Furthermore, the heat dissipation ring is an integral structure and is formed by stamping.

[0008] Furthermore, the heat dissipation ring is made of aluminum.

[0009] Furthermore, the LED module has several LED light sources on the side near the inner lamp cover.

[0010] Furthermore, the inner lampshade is made of milky white PC or PMMA.

[0011] Furthermore, the heat sink body is segmented and conformally attached to the back of the LED module.

[0012] Furthermore, thermal grease is also coated between the heat sink body and the LED module.

[0013] Furthermore, the thickness of the heat sink connecting ribs and the heat sink body is 0.8-1.5mm.

[0014] Furthermore, the width of the radiator connecting rib is 20-30mm.

[0015] Furthermore, the spacing between two adjacent heat sink connecting ribs is 15-20mm.

[0016] By adopting the above technical solution, this utility model has the following beneficial effects:

[0017] 1. The heat dissipation ring of this utility model combines the heat sink and the ring into an integrated structure. Heat is dissipated by directly attaching the heat sink body to the LED module, and then by conducting heat through the heat sink connecting ribs and connecting plate. Finally, heat is dissipated and discharged through the heat dissipation fins. While ensuring excellent heat dissipation performance, it can also serve as a decorative ring, achieving multiple benefits.

[0018] 2. This utility model combines a heat dissipation structure with a decorative ring within a limited space, which can reduce the number of parts, lower material costs, reduce space and increase heat dissipation space. The structure is simple and production and assembly are faster and more convenient.

[0019] 3. The heat dissipation fins of this utility model, while serving as a structural feature, are bent and extended into the inner side of the outer lamp cover. They can utilize their heat transfer to improve the cold zone conditions of the outer lamp cover, optimize the fogging performance inside the lamp cavity, reduce fogging condensation, and ensure the final lighting effect.

[0023] The components include: 1. outer lampshade; 2. heat dissipation fins; 3. inner lampshade; 4. heat sink connecting ribs; 5. LED module; 6. LED light source; 7. heat sink body; 8. mist cooling zone; and 9. connecting plate. Detailed Implementation

[0024] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0025] like Figure 1 , 2 As shown, in this embodiment, an integrated heat dissipation ring structure is provided, which mainly consists of an outer lampshade 1, an inner lampshade 3, an LED module 5, and a heat dissipation ring. The outer lampshade 1 is located on the outer side, the inner lampshade 3 is located on the inner side, and the LED module 5 is disposed behind the back of the inner lampshade 3. Multiple LED light sources 6 are disposed on the surface of the LED module 5 near the inner lampshade 3. The light emitted by the LED light sources 6 can illuminate the inner lampshade 3, and the inner lampshade 3 can be used to uniformly diffuse the direct light from the LED light sources 6. The material of the inner lampshade 3 can be milky white PC or PMMA.

[0026] To achieve multiple functions of heat dissipation and decorative ring within a limited space, this embodiment also includes a heat dissipation decorative ring between the outer lampshade 1 and the inner lampshade 3. Specifically, the heat dissipation decorative ring consists of a heat sink body 7, heat sink connecting ribs 4, a connecting plate 9, and heat dissipation fins 2. The heat sink body 7 is located on the back of the LED module 5. Four heat sink connecting ribs 4 are connected to the heat sink body 7 and located on the side of the inner lampshade 3, forming an angle of approximately 90 degrees with the heat sink body 7. The connecting plate 9 is connected to the four heat sink connecting ribs 4 and located on the front side of the inner lampshade 3. Thirteen heat dissipation fins 2 are connected to the connecting plate 9 and bent towards the outer lampshade 1. In this embodiment, the heat dissipation fins 2 have a rhomboid cross-section, formed by stamping and bending, and their shape can be customized according to the lamp fixture design.

[0027] Specifically, the aforementioned heat dissipation ring is a one-piece structure formed by stamping. Made of aluminum, it ensures excellent heat dissipation performance. The one-piece stamping process using aluminum results in high dimensional accuracy and minimal deformation, achieving cost reduction and efficiency improvement in the overall product structure.

[0028] In the above design, it can be seen that the heat dissipation ring of this embodiment combines the heat sink and the ring into a single structure. Heat dissipation is achieved by directly attaching the heat sink body 7 to the LED module 5, then through the heat sink connecting ribs 4 and connecting plate 9 for heat conduction, and finally through the heat dissipation fins 2 for heat dissipation and exhaust. This design ensures excellent heat dissipation performance while also serving as a decorative ring, achieving multiple benefits. Furthermore, combining the heat dissipation structure with the ring within a limited space reduces the number of parts, lowers material costs, reduces space while increasing heat dissipation capacity, and simplifies the structure, making production and assembly faster and more convenient.

[0029] It is worth mentioning that, for reference Figure 2 As shown, in this embodiment, the heat dissipation fins 2 can not only serve as a structural feature, but also bend and extend into the inner side of the outer lamp cover 1. The heat dissipation fins 2 can conduct heat, thereby improving the fogging cold area 8 of the outer lamp cover 1, optimizing the fogging problem caused by the local cold area of ​​the outer lamp cover 1, reducing fogging, and ensuring the final lighting effect. This achieves multiple benefits in one fell swoop.

[0030] To improve heat dissipation, the heat sink body 7 in this embodiment can be segmented and conformally attached to the back of the LED module 5. The arrangement is tailored to the shape of the back of the LED module 5, and thermal grease is applied between the heat sink body 7 and the LED module 5 to facilitate rapid heat dissipation. Furthermore, to achieve optimal heat dissipation and spatial distribution in this embodiment, the thickness of the heat sink connecting rib 4 and the heat sink body 7 is designed to be 1.5mm, the width of the heat sink connecting rib 4 is designed to be 20mm, and the spacing between adjacent heat sink connecting ribs 4 is designed to be 15mm.
