Light distributing mirror of anti-fog automobile lamp and anti-fog automobile lamp

Abstract

The invention relates to a light distributing mirror of an anti-fog automobile lamp and the anti-fog automobile lamp. The light distributing mirror of the anti-fog automobile lamp is equipped with at least two layers of lenses, wherein a gap between adjacent two layers of lenses is in a sealed vacuum state; and among the adjacent two layers of lenses, the outer layer of lenses can completely or partially shade outer surfaces of the inner layer of the lenses. The lenses can be injection-molded, and are connected in an integrally injection-molded manner or are connected by outer edge welding. The anti-fog automobile lamp comprises a lamp body and the light distributing mirror of the anti-fog automobile lamp, wherein the light distributing mirror is fixedly connected to the lamp body; a lamp cavity is enclosed by the light distributing mirror and the lamp body; and a lamp bulb and a light reflecting mirror are mounted on the lamp body, and are positioned in the lamp cavity. The light distributing mirror can radically solve the fogging problem of the automobile lamp, and does not have phenomena of flowing, flow marks, failure, discoloration and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile lamps, and in particular relates to an anti-fogging structure design of automobile lamps. Background technique [0002] With the rapid development of automobile lamp technology, a large number of new types of lamps have appeared, but the problem of lamp fogging has not been solved. The main reason for the fogging of car lights is that the temperature of the inner surface of the light distribution mirror is lower than the dew point of the air in the lamp cavity, and the water vapor in the air in the lamp cavity condenses into small water droplets on the inner surface of the light distribution mirror, which affects the appearance of the car light and optical effects. [0003] At present, the method of spraying anti-fog coating on the inner surface of the light distribution mirror is mainly used to solve the fogging of car lights. Although the fog can be eliminated visually, the anti-fog coating ...

Problems solved by technology

[0002] With the rapid development of automobile lamp technology, a large number of new types of lamps have appeared, but there has been no good solution to the problem of lamp fogging

The main reason for the fogging of car lights is that the temperature of the inner surface of the light distribution mirror is lower than the dew point of the air in the lamp cavity, and the water vapor in the air in the lamp cavity condenses into small water droplets on the inner surface of the light distribution mirror, which affects the appearance of the car light and optical effects

[0003] At present, the method of spraying anti-fog coating on the inner surface of the light distribution mirror is mainly used to solve the fogging of car lights. Although the fog can be eliminated visually, the anti-fog coating itself will also have various problems such as flow, flow marks, failure, and discoloration. Problem, the anti-fogging effect cannot be maintained for a long time
