차량 램프 성에를 감지하는 성에 감지 제공 장치는 휘도 센서의 차이를 이용하여 낮, 터널, 저녁 구간을 인식하고, Green LED에서 발생한 성에 검출용 파장이 차량 램프로 조사되고, 차량 램프로부터 반사되는 빛을 수신하여 측정한 RGB 센서의 Green 밝기 수광값과, 구간별로 기설정된 RGB 센서에서 측정되는 Green 파장대의 기준 세기값과 비교하여 차량 램프의 성에 상태를 감지하여 성에 감지 성능을 높일 수 있다.
This frost detection providing device for detecting a frost state of a vehicle lamp determines daytime, in-tunnel, and evening periods by using differences of a brightness sensor, irradiates a generated frost-detecting wavelength from a green LED to the vehicle lamp, and compares a green brightness light receiving value of an RGB sensor, measured by receiving light reflected from the vehicle lamp, with a reference intensity value of a green wavelength band measured by the RGB sensor preset for each period so as to detect the frost state of the vehicle lamp, thereby increasing the frost detection performance. According to the present invention, the frost detection performance may be improved by using a difference between a luminance receiving value of a luminance sensor, measured by using external light or ambient brightness, and a reference intensity value of the green wavelength band measured by the RGB sensor preset for each of the daytime, in-tunnel, and evening periods.
