Abstract

The invention relates to an active lamp defogger and humidity removal method thereof, and the fog in a lamp can be removed and restrained through controlling dew point in the lamp by dry air or reducing absolute humidity of the air in the lamp. The active lamp defogger comprises: an active defogging controller which is connected with an electronic control unit for controlling an HVAC device of a vehicle, a humidity detection sensor which is connected with the active defogging controller and is arranegd in the lamp of the vehicle to detect the humidity in the lamp, a dry air supply line which forms a moving path of the dry air of the HVAC device from the HVAC device to the lamp, and a check valve which is arranged on the dry air supply line and is closer to the HVAC device than the lamp. Then the active lamp defogger can rapidly reduce the absolute humidity in the lamp under the dew point temperature to defog or restrain the fog occuring.

Description

technical field [0001] The present invention relates to an active light dehumidifier and a dehumidification method thereof, in particular to an active light dehumidifier capable of removing moisture from headlights and other vehicle lights by using a Heating Ventilating and Air Conditioning (HVAC: Heating Ventilating and Air Conditioning) installed on a vehicle. A lamp dehumidifier and a dehumidification method thereof. Background technique [0002] Vehicles are generally equipped with light devices. Lighting devices include various lights such as headlights, tail lights, fog lights, and direction indicators. Moisture can build up inside the housing of the headlamp. In this case, the light distribution performance of the headlights decreases, which may cause safety accidents. [0003] Moisture problems in vehicle headlamps are now a problem that lamp manufacturers must address. The headlights of the vehicle are arranged on the left and right sides in front of the vehicle...
