Problems solved by technology

[0002] At present, it is generally believed that the greater the power, the greater the brightness, the greater the luminous flux of the lamps used in automobiles, and this requires the installation of heat sinks to reduce the heat generated by high-power lamps, in order to maintain the lamps when they are in use. The temperature will not be too high, but the existing heat dissipation device can not quickly dissipate heat to the lights, and it takes a certain amount of time to make the lights reach a constant temperature state, which affects the reduction of the luminous flux of the lights, especially when the car needs to enter a tunnel, etc. In a dark environment, too slow heat dissipation will easily affect the stability of the lights when they are turned on, and cannot reach the specified luminous flux conditions, resulting in reduced driving safety
In order to increase the luminous flux of the existing LED headlights, it is usually achieved by increasing the power of the lights, but the power is too large, which violates the principle of energy saving and environmental protection of LED lights, increases the difficulty of heat dissipation of LED lights, and burns the lamp beads.
[0003] Under the condition of the voltage of 13.2V and the power of 20.83W, the luminous flux of the car lamp can only reach about 1500lm (such as Figure 8 As shown), if the luminous flux is increased in order to increase the power of the car light, the condition of 30W is achieved, and the lamp bead exceeds the rated power, the heat dissipation device cannot meet the requirements, and the temperature of the lamp bead is high. Even if it can withstand it for a while, the degree of light decay will be larger, and the service life will be shortened faster

Embodiment 1

[0041]In this embodiment, after the copper sheets 3 are scattered, except that the integrated part 31 is compressed, the heat dissipation part 32 is scattered in a flocculent shape, and the protrusions 321 between each copper sheet 3 are pushed apart from each other, which can only be arranged on the The same side of each copper sheet 3 can also be provided with protrusions on both sides, and the protrusions face each other to increase the contact area between the heat dissipation part 32 and the air and speed up the heat dissipation rate.

Embodiment 2

[0043] Different from Embodiment 1, in this embodiment, the heat dissipation portion 32 of the copper sheet 3 extends in a wave shape, and the copper sheets 3 are spread out one by one through the transverse wave-shaped heat dissipation portion 32, as shown in FIG. Figure 4 As shown, such a setting is easier to bend and shape during production, and the shape of the wave can gradually increase in amplitude. The bottom of the wave is opposite to the top of the other wave, forming a large-area contact between the cavity and the air, increasing the effect of heat dissipation .

Embodiment 3

[0045] The difference between this embodiment and Embodiment 2 is that the wave extending direction of the wavy cooling portion 32 is longitudinal, as Figure 5 As shown, the copper sheet 3 will be more orderly, and the bottom end of the wave is easier to align with the top of the other sheet. It can also achieve the purpose of opening the copper sheet 3 and increase the contact area with the air to improve the heat dissipation efficiency.
