Vehicle lamp large-mean-air-permeability waterproof plug with waterproof and breathable material

Abstract

The invention discloses a vehicle lamp large-mean-air-permeability waterproof plug with a waterproof and breathable material. The vehicle lamp large-mean-air-permeability waterproof plug comprises a rubber body with a through hole, a shell with a breathable channel and the waterproof and breathable material; the waterproof and breathable material is arranged at one end of the through hole of the rubber body; and the rubber body is assembled in the breathable channel of the shell. In this way, air in a vehicle lamp and the outside atmosphere can be subjected to convection quickly to drain moisture, thus the electrical performance is not affected by the humid air environment, and the fog condensation phenomenon on the mirror surface of the vehicle lamp or the smooth electronic component surface is eliminated so that the light performance of the vehicle lamp can be brought into play.

Description

technical field [0001] The invention relates to a large air-permeable waterproof plug for a car lamp with waterproof and air-permeable materials. Background technique [0002] With the improvement of the aesthetics of automobile consumption in our country, the appearance of automobile models is mostly streamlined and curved, especially the car lights are the eyes of the car, and the appearance is more curved, vivid and beautiful. The mature use of halogen bulbs and xenon lamps , the new technology of LED headlights has been added; in order to pursue the beauty of modern car lights, their shapes are becoming more and more complex, and the complex shapes also lead to temperature differences in the lamp housing, so after the outside air (humidity) enters, it is very easy to Fog is generated, affecting driving safety. The curved surface of car lights and the new LED headlight technology make the transparent glass bulbs of car lights more foggy and condensed on the inner surface...

AI Technical Summary

Problems solved by technology

The inner shell of some car lamps has a high micro-moisture content, and the water vapor formed by a large amount of micro-moisture burst and released within half an hour of the start of lighting, the inner surface of the lamp shell that has been treated with anti-fog is slow to form a flat water film. , the accumulated water flowing at the bottom of the car light shell turns into water vapor under the influence of the heat of the car light, which increases the humidity inside the car light. Due to the temperature difference, the inner surface of the glass bulb on the curved surface and the sharp corner transition area has more serious fogging and condensation. The beam divergence caused by the fogging and condensation on the inner surface of the coated glass bulb has caused a safety hazard, and the headlights are anti-fog. The investment in the coating production line needs tens of millions of yuan. In fact, it is very uneconomical to make a large investment with poor returns.
