Problems solved by technology

[0002] The material of the car lamp itself has the problem of poor thermal conductivity, which directly leads to uneven temperature of the lamp itself due to poor thermal conductivity, and the air velocity in different temperature regions is therefore different. The air humidity in the area with slow air velocity is high, and the air Affected by the change of external temperature, the water vapor in the water is easy to form fog water in this area.
Especially at the lower corners of the headlights, due to the low temperature and slow air velocity, it is easy to form fog and cannot be evaporated quickly, which directly causes fog to affect the lighting performance and service life of the lights

Embodiment Construction

[0026] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0027] In the present disclosure, unless otherwise stated, the used orientation words such as "upper and lower" usually refer to the orientation shown on the drawing, and the upper and lower parts of the illustration are the upper and lower parts mentioned in the present disclosure. ; "Inside and outside" refers to the inside and outside of the outline of the corresponding parts.

[0028] According to the principle of air flow, when air is heated, its volume expands, and compared with the same volume of cold air, its weight becomes lighter and it rises upward. Therefore, the hot air will rise and concentrate on the upper area of ​​the lamp to form a high tem...

Abstract

The invention relates to a fog water preventing device for an automobile lamp, an automobile lamp assembly and a vehicle. The fog water preventing device for the automobile lamp comprises a heat collection sheet (3) used for being installed onto a high-temperature region (1) on the upper portion of the inside of the automobile lamp, a cooling sheet (5) used for being installed onto a low-temperature region (2) on the lower portion of the inside of the automobile lamp and heat conduction pipes (4) used for being connected between the heat collection sheet (3) and the cooling sheet (5). Heat absorbed by the heat collection sheet can be transmitted to the cooling sheet through the heat conduction pipes, the cooling sheet emits the heat to the low-temperature region so that the purpose of balancing the temperature of the high-temperature region and the temperature of the low-temperature region can be achieved, the temperature of the inside of the automobile lamp is balanced and fog water inside the automobile lamp can be removed quickly.

Description

technical field [0001] The present disclosure relates to the field of anti-fog water for vehicle lights, in particular to an anti-fog water device for vehicle lights, a vehicle light assembly, and a vehicle. Background technique [0002] The material of the car lamp itself has the problem of poor thermal conductivity, which directly leads to uneven temperature of the lamp itself due to poor thermal conductivity, and the air velocity in different temperature regions is therefore different. The air humidity in the area with slow air velocity is high, and the air Affected by the change of external temperature, the water vapor in the air is easy to form mist in this area. Especially at the lower corners of the headlights, due to the low temperature and slow air velocity, it is easy to form fog and cannot be evaporated quickly, which directly causes fog to affect the lighting performance and service life of the lights. Contents of the invention [0003] The purpose of the pres...
