Problems solved by technology

[0002] The problem of fog has always been a problem that automobile lamps often encounter. With the advancement of manufacturing technology, lamps have more and more functions and more and more complex shapes. Too much will lead to short circuit of electronic components, affecting the use of users
[0003] According to the current market feedback, there are a large number of market returns due to fog problems, so good anti-fog measures are particularly important. Hygroscopic substances are more and more widely used in lamps, while conventional anti-fog coatings and desiccants have small moisture absorption. And it is a one-time measure. After the failure, it cannot be replaced but the lamp can only be replaced. The cost is too high, and the fog problem will still occur after the service life ends

Abstract

The invention discloses a dehumidification device based on moisture absorption substances. The device comprises the moisture absorption substances, a mounting base used for fixing the moisture absorption substances and a sealing ring. The moisture absorption substances are put in a cylindrical or polygonal packaging shell. The mounting base is mounted on a lamp shell in a rotary mounting manner. The lamp shell and the mounting base are sealed through the sealing ring. According to the device, on the basis of adopting the efficient and high-moisture-absorption-capacity moisture absorption substances, the function that the moisture absorption substances can be replaced is added, and the problem of mist caused by failures of the moisture absorption substances is solved by replacing the moisture absorption substances; and for a lamp without moisture absorption substances, the device can be additionally arranged through a base mounting groove reserved in a shell.

Description

technical field [0001] The invention relates to a dehumidifying device based on hygroscopic substances, which is used to prevent or eliminate fog in lamps. Background technique [0002] The problem of fog has always been a problem that automobile lamps often encounter. With the advancement of manufacturing technology, lamps have more and more functions and more and more complex shapes, especially the LED lamps that are gradually popularized now. Too much will lead to short circuit of electronic components and affect the use of users. [0003] According to the current market feedback, there are a large number of market returns due to fog problems, so good anti-fog measures are particularly important. Hygroscopic substances are more and more widely used in lamps, while conventional anti-fog coatings and desiccants have a small amount of moisture absorption. And it is a one-time measure. After it fails, it cannot be replaced but only the lamp. The cost is too high, and the fog...
