Abstract

야간 정차중의 차에 대한 추돌사고를 방지하는 것을 목적으로 한다. 장착대(2)에 추돌방지용 발광체(3) 및 야간, 후방에서 접근해오는 챠량 헤드라이트 빛을 감지하기 위한 광센서(1)를 설치한다. 상기 광 센서(1)가 헤드라이트 빛을 감지했을 때에 일정시간 발광체(3)가 발광된다.It aims to prevent a collision accident of a car stopping at night. On the mounting table 2, an anti-collision light-emitting body 3 and an optical sensor 1 for detecting a vehicle headlight light approaching at night and rear are installed. When the light sensor 1 detects the headlight light, the light emitter 3 emits light for a predetermined time.
