Vehicle LED illuminating lamp with waterproof and dustproof functions

Abstract

The invention discloses a vehicle LED illuminating lamp with waterproof and dustproof functions, and belongs to the technical field of vehicle lamps. The vehicle LED illuminating lamp comprises a mounting box body, wherein the right side surface of the mounting box body is clamped with the left side surface of a heat conduction fixing cover, and the left side surface of the mounting box body is in lap joint with the right side surface of a glass protective cover; and the surface of the mounting box body is fixedly connected with the inner wall of an annular protective steel mesh. According to the vehicle LED illuminating lamp with the waterproof and dustproof functions, by arranging the driving fan blades, the driven fan blades, the driving rotating shaft, the driven rotating shaft, the sealing barrel, the sliding rod, a tooth groove, a gear, a transmission wheel and a cooling backflow hole, gas continuously enters the heat conduction fixing cover, so that the gas in the heat conduction fixing cover is high in pressure, and the interior of the mounting box body is under negative pressure; thus, the LED lamp panel assembly is arranged in the mounting box body, then the air enters the mounting box body again through the cooling backflow holes after being cooled and is directly blown to the right side face of the LED lamp panel assembly through the cooling backflow holes, so that heat of the LED lamp panel assembly is dissipated; in this way, internal heat can be stably dissipated, and stable cooling of the automobile lamp in the traveling use process is kept.

Description

technical field [0001] The invention belongs to the technical field of vehicle lamps, in particular to a vehicle LED lighting lamp with waterproof and dustproof functions. Background technique [0002] At present, with people's emphasis on environmental protection and energy saving, LED lighting has been popularized. More and more lighting equipment use LED as light source. However, xenon lamp is still used as lighting source in vehicle lighting equipment. The reason is because The working conditions of vehicle lighting equipment are harsh, and LED light sources have relatively high requirements for working conditions. With the gradual improvement of vehicle off-road performance by current car owners, multiple dome lights will be installed on the top of unsealed vehicles, which is convenient for outdoor areas. Lighting, LED car lights are cold light sources, generally low power consumption, more than 70% energy saving than traditional light sources, no ultraviolet and infrar...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waterproof and dustproof LED lighting lamp for vehicles, which solves the problem that most of the current LED lighting lamps for vehicles are replaced with the outside air during long-term driving. Heat dissipation will cause water or dust to enter the interior easily and cause damage. At the same time, the closed heat dissipation structure will cause the internal heat to dissipate slowly. When it is used for a long time, the closed waterproof and dustproof structure will prevent the internal heat from dissipating, resulting in internal LED lights. The problem that the service life is greatly affected
