A kind of LED lighting lamp with waterproof and dustproof function

Abstract

The invention discloses a vehicle LED lighting lamp with waterproof and dustproof functions, which belongs to the technical field of vehicle lamps. The left side of the installation box is overlapped with the right side of the glass shield, and the surface of the installation box is fixedly connected with the inner wall of the annular protective steel mesh. The vehicle LED lighting with waterproof and dustproof function is provided with the active fan blade, the driven fan blade, the driving shaft, the driven shaft, the sealing cylinder, the sliding rod, the tooth slot, the gear, the transmission wheel and the cooling return hole. As the gas continues to enter the inside of the heat-conducting fixing cover, the gas inside the heat-conducting fixing cover is at high pressure, and the inside of the installation box is under negative pressure, so that the gas cools down and re-enters the inside of the installation box through the cooling return hole, and the airflow passes through the cooling The return hole is directly blown on the right side of the LED light board assembly to take away its heat. This way, the internal heat can be stably dissipated, and the lights can be cooled steadily during driving.

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 attention to environmental protection and energy saving, LED lighting has been popularized, and more and more lighting equipment uses LED as the light source. However, the xenon lamp is still used as the lighting source in the vehicle lighting equipment. The reason is because The working conditions of automotive lighting equipment are harsh, and the LED light source has relatively high requirements for working conditions. Lighting, LED car lights are cold light sources, generally low power consumption, more than 70% energy saving than traditional light sources, no ultraviolet and infrared rays in the spectrum, neither heat nor radiation, little glare, and waste can be recycled, no The pollution does not contain mercury and can be safely touched. It i...

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
