Car lamp back cover with infrared radiation drying and exhaust function with valve plate structure

Abstract

The invention discloses a car lamp rear cover with infrared radiation drying and exhaust functions of a valve plate structure, comprising: end covers provided with a plurality of vent holes, a connecting seat for connecting with the car lamp housing, and infrared radiation drying and exhaust The membrane component, the end cover and the connecting seat are assembled and connected to form the rear cover of the lamp. The membrane component is built into the cavity of the rear cover of the lamp. The valve slice is automatically opened and closed under the push of air pressure difference. Through the above method, the present invention can ensure that there is no fogging and condensation phenomenon in the housing of automobile lamps and electrical and electronic equipment, so that the electrical performance is not affected by the humid air environment, and the mirror surface or smooth surface of the housing of automotive electrical and electronic equipment There will be no mist on the surface of electronic components, so that the performance of automotive electrical and electronic equipment can be brought into play, and the infiltration of dust can be blocked, so that the housing of automotive electrical and electronic equipment can reach a dust-tight level without pollution.

Description

technical field [0001] The invention relates to a car lamp back cover with infrared radiation drying and exhaust functions of a valve plate structure. Background technique [0002] With the improvement of the aesthetics of automobile consumption in our country, the appearance of automobile models is mostly streamlined and curved, especially the car lights are the eyes of the car, and the appearance is more curved, vivid and beautiful. The mature use of halogen bulbs and xenon lamps , the new technology of LED headlights has been added; in order to pursue the beauty of modern car lights, their shapes are becoming more and more complex, and the complex shapes also lead to temperature differences in the lamp housing, so after the outside air (humidity) enters, it is very easy to Fog is generated, affecting driving safety. The curved surface of car lights and the new LED headlight technology make the transparent glass bulbs of car lights more foggy and condensed on the inner su...
