Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to a highly efficient heat dissipation vehicle lamp with a porous structure. Background Art

[0002] The heat dissipation solution for automotive lights is mainly for LED lights, because LED lights will generate heat during use. If the heat cannot be effectively dissipated, the performance and life of the LED will be affected. The following are several common heat dissipation solutions for automotive lights:

[0003] Passive heat dissipation: Passive heat dissipation usually involves combining the LED lamp with the heat sink tightly and dissipating heat through the contact between the fins on the surface of the heat sink and the air. In order to reduce the thermal resistance between the heat sink and the LED circuit board, a thermal conductive medium such as thermal grease or thermal conductive glue is usually filled between the two.

[0004] Active cooling: Active cooling methods include liquid cooling, heat pipes and air cooling. In automotive lights, air cooling is more common because of its low price and simple installation. By adding a fan, air flow can be forced to improve heat dissipation efficiency.

[0005] Heat sink design: Heat sink design is also an important part of the heat dissipation solution. The shape, material and surface treatment of the heat sink will affect its heat dissipation performance. For example, the height and length of the heat sink fins and the flow rate of the surrounding air will affect the temperature of the LED module.

[0006] However, traditional passive heat dissipation structures mostly rely on thermally conductive materials. During long-term use, the thermal conductivity of the thermally conductive materials will decrease, and the thermal conductivity and heat dissipation performance will decrease, which will affect the normal use of the car lights and needs to be improved urgently.

[0043] In this embodiment, a second fin 116 is arranged at the end of the connecting seat 111 facing away from the first fin 114. The use of the double-fin structure is beneficial to further improving the heat conduction efficiency of the connecting seat 111.

[0044] As Figures 1 to 5 shown, further, the top cover 120 and the bottom cover 130 are symmetrically installed at the top and bottom of the connecting seat 111. The two edges of the top cover 120 are respectively fixedly connected to the mounting seat 112 and the mounting plate 113. The two edges of the bottom cover 130 are respectively fixedly connected to the mounting seat 112 and the mounting plate 113. In this embodiment, both the top cover 120 and the bottom cover 130 are made of metal aluminum or metal copper.

[0045] As Figures 1 to 5 shown, further, the top cover 120 and the bottom cover 130 have the same structure. The cross-section of the top cover 120 is arranged in a C-shaped structure. The heat dissipation holes 600 are arranged through the two ends of the top cover 120.
