Car lamp structure preventing water vapor condensation of car lamp

Abstract

The invention relates to a car lamp structure preventing water vapor condensation of a car lamp. The car lamp structure comprises a lamp shell, a lampshade, a light source base and a light source, wherein the lampshade is matched with the lamp shell, the light source base is arranged on the lamp shell, and the light source is fixedly installed on the light source base. A first connector is formed in the portion, close to a light source area, of the lamp shell. A second connector is formed in the portion, away from the light source area, of the lamp shell. The first connector is communicated with the second connector through a ventilation bending pipe. The ventilation bending pipe is suspended outside the lamp shell. The requirements for contraction and expansion of a working medium inside the car lamp are met, and meanwhile, due to the facts that the flowing inside working medium inside the car lamp is accelerated and external water vapor is separated, the phenomenon of the water vapor condensation of the car lamp can be well prevented from happening. Due to the facts that that the bending pipe is arranged in the surrounding outside the lamp shell and the environment temperature is lower, when the light source is lightened, the energy transferring of a lamp body can be accelerated, and the heat-resisting problem of the car lamp can be well solved. Due to the fact that the two ends of the bending pipe are fixed on the lamp shell and the bending pipe is not communicated with the external world, the problem that external impurities enter the car lamp is effectively solved.

Description

technical field [0001] The invention belongs to the car lamp technology, and in particular relates to a car lamp structure for preventing water vapor condensation of the car lamp. Background technique [0002] At present, the water vapor condensation problem of automobile lights, especially headlights, is a common appearance problem in today's automobile market. The reason for the formation of water vapor condensation is the uneven temperature distribution in the inner cavity of the lamp and the uneven distribution of the flow field. When the temperature in some areas is lower than the condensation temperature of water, condensation cores will be formed, thereby forming water vapor on the inner surface of the lamp body mask Even water droplets seriously affect the appearance of the lamp body, and have a great impact on the life and conductivity of the electronic parts in the lamp body. [0003] At present, the more popular way to solve this problem is to spray a layer of an...

AI Technical Summary

Problems solved by technology

Practice has proved that for lamps with complex shapes and designs, the phenomenon of water vapor condensation cannot be completely eliminated by using all the methods mentioned above.

Therefore, there is no long-term effective and low-cost technology for how to effectively eliminate the water vapor condensation in the lamp
