PROBLEM TO BE SOLVED: To effectively prevent freezing of a vehicle headlight in an environment with low outside air temperature.SOLUTION: An antifreezing device for a vehicle headlight includes: an outside air temperature detection sensor for detecting the outside air temperature of a vehicle; a vehicle speed detection sensor for detecting the speed of the vehicle; and a control unit for controlling an air conditioning unit mounted on the vehicle, on the basis of the detection results of the outside air temperature detection sensor and the vehicle speed detection sensor. When a result of detection by the outside air temperature detection sensor is equal to or less than a predetermined value and if the vehicle speed detection sensor detects the stop of the vehicle, the control unit reversely rotates a rotation direction of a condenser fan 110 to flow the wind used for radiating the heat of the condenser in a direction opposite to the direction to be circulated so as to blow the warm air warmed with the radiated heat from the condenser, via a passage 113, toward the outer surface side of an outer cover 3.SELECTED DRAWING: Figure 3

    【課題】外気温が低い環境下における車両用前照灯の凍結を効果的に防止することができる。【解決手段】車両の外気温を検知する外気温検知センサと、車両の速度を検知する車速検知センサと、外気温検知センサおよび車速検知センサによる検知結果に基づいて、車両に搭載された空調ユニットを制御する制御部と、を備え、制御部は、外気温検知センサによる検知結果が所定値以下であって、車速検知センサにより車両の停止を検知した場合、コンデンサの放熱に伴って温められた温風を、通路113を介してアウターカバー3の外表側へと送風させるように、コンデンサファン110の回転方向をコンデンサの放熱に用いられる風を流通させる方向とは逆方向に流すように逆回転させる。【選択図】図3
