Abstract
본 발명은 헤드 램프의 전구에 입력되는 전압을 제어하여 한쌍의 전구에서 약 3단계의 밝기를 출력할 수 있는 펄스 폭 변조 방식을 응용한 로우-하이 일체형 헤드 램프를 제공하기 위한 펄스 폭 변조 방식을 응용한 로우-하이 일체형 헤드 램프에 관한 것이다. 이를 위해 본 발명은 서로 다른 크기의 저항을 병렬로 연결하여 기준 저항에 의해 결정된 전압을 출력하는 전압 출력 수단과, 상기 전압 출력 수단으로부터 출력되는 전압을 입력 받아 기준 전압과 비교하여 헤드 빔의 크기를 제어하여 펄스신호를 발생하는 헤드 램프 빔 제어 신호 발생 수단과, 상기 헤드 램프 빔 제어 신호 발생 수단으로부터 출력되는 빔의 크기에 따라 서로 다른 크기의 밝기를 출력하는 헤드 램프 수단을 구비한 것이다.The present invention provides a pulse width modulation method for providing a low-height integrated head lamp using a pulse width modulation method capable of controlling a voltage input to a light bulb of a head lamp and outputting about three levels of brightness from a pair of light bulbs. It relates to a low-high integrated headlamp applied. To this end, the present invention provides a voltage output means for outputting a voltage determined by the reference resistance by connecting a resistor of different sizes in parallel, and receives the voltage output from the voltage output means to compare the reference voltage with a reference voltage to determine the size of the head beam. Head lamp beam control signal generating means for controlling and generating a pulse signal, and head lamp means for outputting brightness of different sizes according to the size of the beam output from the head lamp beam control signal generating means.
