Abstract

본 발명은 차량용 광센서를 이용한 자동 비상 점등회로에 관한 것으로, 일반적으로 차량의 비상등 점멸 스위치가 대대분 인스투르먼트 판넬의 계기판이 소정 위치에 부착되어 있거나 또는 스티어링 컬럼 상의 스티어링 휠 뒷쪽에 위치하여 있어서 아주 급한 경우 등에는 비상등을 점멸시키는 동작이 운전자가 비상대처동작에 방해가 될 수도 있는 문제점을 해소하기 위하여, 차량의 인스트루먼트 판넬 상의 소정 위치에 구비되어 주위의 조도의 변화를 감지하여 신호를 검출하는 광센서부(1)에서 검출되는 신호를 입력받아 램프 제어스위치를 구동시키기 위한 인테페이스부(2)와, 상기 인터페이스부(2)의 출력 신호에 따라 램프의 온ㆍ오프를제어하는 스위치부(3)와, 상기 스위치의 온ㆍ오프에 따라 점멸되는 램프(4)로 이루어지므로써 주행중인 차량이 터널이나 또는 산모퉁이 등과 같이 어두운 지역을 통과할 때에 주위 조도의 변화를 즉시 감지하여 자동적으로 비상등을 점등시키게 할 수 있는 효과가 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic emergency lighting circuit using an optical light sensor for a vehicle. In general, an emergency light flashing switch of a vehicle is usually mounted at a predetermined position on an instrument panel of an instrument panel or behind a steering wheel on a steering column. In such cases, in order to solve the problem that the operation of flashing the emergency light may interfere with the driver's emergency response operation, an optical sensor is provided at a predetermined position on the instrument panel of the vehicle and detects a signal by detecting a change in ambient illumination. An interface unit 2 for receiving a signal detected by the unit 1 to drive a lamp control switch, a switch unit 3 for controlling on / off of a lamp in accordance with an output signal of the interface unit 2; , The vehicle being driven is composed of a lamp (4) which blinks according to the on / off of the switch. When passing through a dark area such as a null or a mountain corner, there is an effect of immediately detecting a change in ambient light and automatically turning on an emergency light.
