Embodiment 1

[0024] like figure 1 and figure 2 As shown, a 30W high-efficiency heat-dissipating LED automobile headlight includes a lamp post 6 and a lamp holder 3, the lamp holder 3 and the lamp post 6 are fixed in an integrated structure by welding, and the lamp holder 3 supports the lamp post 6 and the The effect of accelerating the heat dissipation rate of the lamp post 6 .

[0025] The bottom surface of the lamp holder 3 is fixedly connected with a circular cooling fin group 4 by welding. The cooling fin group 4 can quickly dissipate the heat transferred from the lamp post 6 to the lamp holder 3, speed up the heat dissipation rate of the lamp, and reduce the Junction temperature, to prevent the LED light source 7 from being damaged due to excessive junction temperature. The cooling fin group 4 is provided with a groove 5 for arranging the fan 2; a mounting hole 10 and an elliptical hole 11 for accommodating wires to pass through are also provided.

[0026] The fan 2 is placed in t...

Embodiment 2

[0036] like Figure 4 and Figure 5 As shown, a 30W high-efficiency heat-dissipating LED automobile headlight includes a lamp post 112 and a lamp holder 111. The lamp holder 111 and the lamp post 112 are fixed in an integrated structure by welding, and the lamp holder 111 supports the lamp post 112 and the lamp holder. The effect of accelerating the heat dissipation rate of the lamp post 112 .

[0037] The bottom surface of the lamp holder 111 is fixedly connected with a circular cooling fin group 117 by welding. The cooling fin group 117 can quickly dissipate the heat transferred from the lamp post 112 to the lamp holder 111, accelerate the heat dissipation rate of the lamp, and reduce the Junction temperature, to prevent the LED light source 113 from being damaged due to excessive junction temperature. The cooling fin set 117 is provided with a groove 118 for arranging the fan 119 ; it is also provided with a mounting hole 126 and an elliptical hole 127 for accommodating w...

Abstract

The invention discloses an efficient radiating LED automotive headlamp which comprises a lamp pole and a lamp holder. The bottom face of the lamp holder is fixedly connected with a radiating device which comprises a fan and a radiating fin set which is arranged in a groove. The fan is detachably fixed in the groove of the radiating fin set. When the efficient radiating LED automotive headlamp works, generated heat is transferred to the radiating fin set to be radiated through heat transfer, the fan rotates, the flow rate of the air around the radiating fin set is improved, and therefore the radiating speed of the radiating fin set is increased. The efficient radiating LED automotive headlamp is particularly suitable for large-power lamp structures.

Description

technical field [0001] The invention relates to an LED automobile lamp, in particular to a high-efficiency heat dissipation LED automobile headlamp. Background technique [0002] As we all know, with the progress of society, cars have now widely entered people's lives. As a means of transportation, cars need to have the ability to run at night or in dark environments, so now cars or motor vehicles are equipped with headlights. [0003] In the development process of automobile lights, it has successively experienced several development stages of electric light source headlights, double-beam wick headlights, asymmetric low-beam headlights, halogen tungsten headlights, xenon-filled bulbs, and xenon bulbs. [0004] For a long time, the automotive light source market has been dominated by halogen lamps and xenon lamps. However, these two traditional lighting lamps have fatal weaknesses in terms of brightness, life, volume, heat generation, color temperature adjustment, and robus...
