Problems solved by technology
However, not only external air for dehumidification but also foreign substances flow in through the openings, thereby causing a problem of lowering the watertight performance of the lamp housing.
[0006] In addition, the Japanese Laid-Open Patent provides a filter in the opening to prevent the inflow of foreign substances, but since the moisture inside the lamp housing of the filter is not easily discharged to the outside, there is a need for an additional power source for moisture removal. The problem
[0007] On the other hand, a thin water film is generally formed on the inner surface of the lamp housing, and an expensive hydrophilic paint is applied to prevent moisture from being observed. However, if excessive moisture is generated in this case, not only running water will occur The problem of watermarks, and the problem of increasing product costs due to the high cost of hydrophilic coatings

Disclosed is an air vent device for a vehicle lamp, including: an inner housing which is installed on a lamp housing, has an opening portion formed at one side thereof, and has a moisture generation inducing zone that is formed in the inner housing and generates moisture; and an outer housing which has a low pressure inducing unit that is formed between the inner housing and the outer housing and allows the outside air to pass therethrough, and discharges the moisture generated in the moisture generation inducing zone to the outside through the opening portion and the low pressure inducing unit.
Description
technical field [0001] The present invention relates to a vent device for a vehicle light, and more specifically, the vent device for a vehicle lamp is for effectively removing moisture generated inside a vehicle light module. Background technique [0002] Generally speaking, in order to ensure visibility when driving at night, a vehicle is equipped with a lamp module that irradiates light in the direction of travel. [0003] The lamp module irradiates intense light from a light source unit that receives power and generates constant heat, and the light irradiated by this irradiated light ensures a driving field of view ahead of the vehicle. [0004] However, according to the prior art vehicle headlamp module, due to the temperature difference between the high temperature inside the lamp module and the low temperature outside due to the heat generated from the light source part, unexpected moisture is generated, and the moisture adheres to the device provided in front of the ...
