Description

Headlamp convenient for removing water vapor of lampshade and working method Technical Field The invention relates to the field of vehicles, in particular to a headlamp capable of facilitating removal of water vapor of a lampshade and a working method. Background The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. The automobile headlight assembly is not completely sealed, and is usually provided with a ventilation opening, and the lamp is high in temperature no matter a halogen lamp, a xenon lamp or an LED lamp is lighted, so that the air in the headlight can slowly become high along with the rising pressure of the temperature and is filled in the whole headlight, and when the air humidity is large and the temperature difference between the inside and the outside is too large, water vapor is easy to adhere to a lampshade, and the automobile headlight assembly is just like front windshield fogging. For example, the vehicle lamp is used for too long, the vehicle is put in warehouse or is stopped to be directly turned off, the internal temperature of the headlight is higher, the ambient humidity or the temperature difference is larger, water vapor generated by the headlight is generated, the water vapor is not easy to disperse in a period of time, the penetrating power of the headlight light is greatly reduced, the conditions of light dispersion, road illumination and the like are caused, the normal use of the headlight is influenced, short circuit is caused in severe cases, and important hidden hazards are buried for safe driving.
