Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, solve the problem that when the existing LED automobile headlights are used for a long time, the lamp beads and the circuit components inside the lamp holder will generate a lot of heat, which will easily cause the circuit components inside the lampshade to be damaged due to overheating, making It is difficult for LED car lights to work normally, and a kind of LED car headlight proposed by the present invention

specific Embodiment approach

[0028] As a specific embodiment of the present invention, a No. 1 block 331 is provided in the end of the cooling hole 33 close to the lamp bead 3 . The surfaces are in contact, and the No. 1 block 331 is connected to the inner surface of the cooling hole 33 through the No. 1 elastic rope 332; through the action of the No. 1 block 331, the cooling air flowing out of the cooling hole 33 acts on the surface of the lamp bead 3 evenly, The lamp bead 3 is further subjected to cooling; when working, when the cooling air flows out from the cooling hole 33, it is blocked by the No. 1 block 331, and the No. 1 block 331 is moved under pressure by the impact of the flowing cooling air, so that the cooling air flows from The gap between the No. 1 block 331 and the inner surface of the cooling hole 33 flows out; because the surface of the No. 1 block 331 opposite to the cooling hole 33 is arc-shaped, the cooling wind flowing along the arc-shaped surface of the No. 1 block 331 is further con...

Abstract

The invention relates to the technical field of LED vehicle lights, in particular to an LED vehicle headlight; comprising a lampshade, a spotlight cover, a lamp bead, a fixing seat, a lamp holder, cooling fins, a lamppost and a cooling fan, the lampshade Installed at the end of the condenser, and the condenser is installed on the car body; the present invention arranges a cooling fan inside the lamp holder, and the cooling air generated by the cooling fan flows along the No. 1 through hole And act on the lamp holder and lamp post, so that the circuit components inside the lamp holder and lamp post are cooled; then the cooling air flows out from the cooling hole and directly acts on the lamp beads, so that the heat of the lamp beads is transferred to the air with the cooling air; Finally, the heat flows out from the vents along with the air, so that the temperature inside the lampshade is effectively controlled.

Description

technical field [0001] The invention relates to the technical field of LED vehicle lamps, in particular to an LED vehicle headlamp. Background technique [0002] LED car lights refer to car lights that use LEDs (light-emitting diodes) as light sources. Because LED has the characteristics of high brightness, rich color variety, low power consumption, and long life, LED is widely used in the automotive field. Common exterior lights include: headlights, fog lights, license plate lights, reversing lights, brake lights, turn signals, position lights, position lights, parking lights, warning lights, and daytime running lights. The light colors of external lamps are generally white, orange and red; vehicles that perform special tasks, such as fire trucks, police cars, ambulances, and emergency vehicles, use red, yellow or blue flashing warning lights that have priority to pass. Motor vehicles should participate in safety inspections and comprehensive inspections on time to ensure...
