Anti-fog vehicle lamp

Abstract

The invention discloses an anti-fog vehicle lamp. The lamp includes a housing, a surface shield, a ventilating pipe and an anti-fog device; the housing is connected with the surface shield, a vent hole is formed in the housing, one end of the ventilating pipe is communicated with the vent hole, and the other end of the ventilating pipe is connected with the surface shield and communicated with a cavity formed by the housing and the surface shield; during work of a headlamp, air exchange is conducted between the interior of the headlamp and the exterior of the headlamp through the vent hole tobalance the pressure of the air in the headlamp, after the air is circulated, the air can be guided into the surface shield through the ventilating pipe, correspondingly air circulation of the surfaceshield is achieved, and fogging of the headlamp is avoided. In order to further improve the anti-fog effect of the headlamp, the anti-fog vehicle lamp also includes the anti-fog device, the anti-fogdevice includes an air blowing pipe, a fan and a humidity sensor, and the anti-fog device is mounted on the side, away from the surface shield, of the housing and arranged in the lamp; after the humidity sensor senses the internal humidity of the lamp, the anti-fog device blows air into the headlamp to accelerate the air circulation, and a fogging problem of the lamp is fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an anti-fog automotive lamp. Background technique [0002] In today's automotive lighting manufacturing industry, design, manufacturing, and technology are becoming more and more mature, and the quality of automotive lights is becoming more and more perfect. But so far, the fogging of lamps is still a main reason affecting the quality of car lights. The water vapor in the lamp condenses and condenses on the inner surface of the mask, which not only affects the appearance of the lamp, but also seriously affects the lighting effect of the lamp and seriously affects driving safety. The fog beads formed by fogging are one of the main sources of water accumulation in the lamps, and due to the existence of fogging phenomenon, the water accumulation in the lamps will be caused twice, which will become the cause of fogging again, seriously affecting the service life of the lamps, and...
