Vehicle rear combined lamp

Abstract

The invention discloses a vehicle rear combined lamp. The vehicle rear combined lamp comprises a lamp shell and a lens; the lens is tightly connected with the lamp shell, and includes an inner layer and an outer layer; a thermal insulating layer is arranged between the inner layer and the outer layer, and is a vacuum layer; a circulating device for forming internal circulation of gas in the lamp shell is arranged in the lamp shell, and includes a gas sucking pipe, a gas blowing pipe and a fan for connecting the two; a reflecting cup is arranged in the lamp shell, and is provided with a hole for passing through a light source; and the gas sucking pipe and the gas blowing pipe are both positioned in the hole of the reflecting cup, and are symmetrically arranged about the axis of the reflecting cup. The lens is set as two layers, so that the temperature difference of the inner and outer two sides of the lens is reduced, the fogging on the surface of the lens is prevented, and the influence on the effect of the lens by fog is prevented, and the driving safety is improved.

Description

technical field [0001] The invention belongs to the field of automobiles, and more specifically relates to an automobile rear combination lamp. Background technique [0002] At present, the problem of water vapor condensation in automobile lights is a long-standing problem in the Chinese market. At present, the demand of the automobile industry is that the headlights should be as little as possible during use (disappear within a certain period of time) or that there will be no "fogging" phenomenon, and most of the headlights have this phenomenon, which cannot be avoided, especially in autumn and winter. season. The principle and phenomenon of "condensation fog" are as follows: when the car lights are turned on, a high-temperature and high-humidity environment will be formed. (or foggy) state, when the headlights are turned on for a certain period of time, the internal surface will form a "condensation fog" phenomenon, especially at the light distribution mirror.

Problems solved by technology

At present, the demand of the automobile industry is that the headlights should be as little as possible during use (disappear within a certain period of time) or that there will be no "fogging" phenomenon, and most of the headlights have this phenomenon, which cannot be avoided, especially in autumn and winter. season

The principle and phenomenon of "condensation fog" are as follows: when the car lights are turned on, a high-temperature and high-humidity environment will be formed. (or foggy) state, when the headlights are turned on for a certain period of time, the internal surface will form a "condensation fog" phenomenon, especially at the light distribution mirror. On the inner side of the rear combination lamp, fog is easily formed on the inner surface of the light distribution mirror, which weakens the light transmission effect, especially at the taillight of the car. If fogging occurs, the light intensity will be greatly weakened. In foggy days or low visibility weather, When braking, the vehicles behind will not be able to see the brake lights of the vehicle in front, which will affect driving safety
