Method for removing water vapor condensation in automobile lamp and automobile lamp casing structure with replaceable desiccant bag

Abstract

The invention discloses an automobile lamp casing structure with a replaceable desiccant bag. Desiccant is arranged in a casing of the automobile lamp and especially arranged in a connecting cover of the casing of the automobile lamp. The thought of the method is to govern water vapor to solve the problem of the water vapor condensation in the automobile lamp, the water vapor in the automobile lamp is directly adsorbed by the desiccant, and the problem of the water vapor in the automobile lamp is completely solved. The traditional thought is to prevent steam from entering the casing of the automobile lamp or discharge the steam out of the casing of the automobile lamp so that the problem of the water vapor in the automobile lamp can not be completely solved. The automobile lamp casing structure with the replaceable desiccant bag is easy to install and dismount, capable of facilitating replacement of the desiccant bag during after-sales maintenance, low in manufacture cost and after-sales warranty cost, and applicable to most of semi-closed automobile lamps of the automobile.

Description

technical field [0001] The invention belongs to the vehicle lamp technology, and in particular relates to a technology for preventing water vapor condensation in the vehicle lamp. Background technique [0002] 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...

Problems solved by technology

The use of anti-fog paint requires a special manufacturing process and special manufacturing materials, so the cost is very high

And 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 only new lamps can be replaced, resulting in high maintenance costs.

Chinese patent applications 2005100280821.1 and 201020537421.5 and other disclosed technologies solve the problem of car lights by removing the gas that generates heat when the car lights are in use; they cannot effectively solve the problem of water vapor condensation in the car lights

However, the existing waterproof problem of car lights is to prevent water from entering the car lights. How to solve the problem of water vapor condensation in car lights, there is no long-term effective and low-cost technology.
