Abstract

본 발명은 자동차로 야간 주행시 외부 차량의 라이트에 의해 운전자의 시력이 저하되는 것을 방지하기 위해 실내등의 조도를 운전자가 직접 조절할 수 있도록 하는 자동차 실내등의 조도 조절 장치에 관한 것으로, 실내등의 밝기에 따른 전압의 크기와 운전자가 조절한 저항값에 따른 전압의 크기에 대한 오차의 크기에 따라 실내등의 밝기가 조절되도록 함으로써 외부 차량에 의한 라이트 밝기와 차실내 밝기의 차이에 의한 피로감이 감소되고 전방에 대한 시야가 확보되어 안전 운행이 가능하게 된다.The present invention relates to an illumination control device of a vehicle interior light that allows the driver to directly adjust the illumination of the interior light in order to prevent the driver's eyesight from being degraded by the light of the external vehicle when driving at night by a car, the voltage according to the brightness of the interior light By controlling the brightness of the interior light according to the magnitude of the error and the magnitude of the error of the voltage according to the resistance value adjusted by the driver, the fatigue caused by the difference between the light brightness by the external vehicle and the interior brightness is reduced and the field of vision for the front is reduced. Is secured and safe driving is possible.
