Description

Method for Eliminating Water Vapor Condensation in Automobile Lamp and Automobile Lamp Housing Structure with Replaceable Desiccant Pack

technical field

The invention belongs to the vehicle lamp technology, and in particular relates to a technology for preventing water vapor condensation in the vehicle lamp. the

Background technique

At present, the problem of water vapor condensation in automobile lights, especially headlights, is a long-term problem in the Chinese market. Under the situation that the shape of the headlight and the structure have been finalized, the main solution at present is to apply anti-fog paint on the inner surface of the headlight lens. However, the use of anti-fog paint requires a special manufacturing process and special manufacturing materials, so the cost is very high. Moreover, the anti-fog paint scheme itself has only one year of quality guarantee period. After the warranty period, due to the manufacturing process, the lamps cannot be repaired and can only be replaced with new lamps, resulting in high maintenance costs. Chinese patent application 2005100280821.1 and 201020537421.5 and other disclosed technologies solve the car lamp problem by removing the gas generated during use of the car lamp; they cannot effectively solve the problem of water vapor condensation in the car lamp. And the existing car lamp waterproof problem is to prevent water from entering the train of thought in the car lamp. How to solve the problem of water vapor condensation in the car lamp, there is no technology that is both long-term effective and low in cost. the
