Abstract

본 발명은 전원차단시 비상등 점등장치에 관한 것으로, 외부로부터 교류전원이 변압부를 통해 설정된 소정전압으로 변압된 다음 정류부에서 직류전원으로 정류되어 제어부로 제공되고 제어부로부터의 스위칭신호에 의거하여 제1트랜지스터가 턴온되어 저항을 통해 충전부에 직류전원이 충전된다. 이때, 정류부로부터 직류전원이 제공되지 않으면 제어부로부터의 로우레벨신호에 의거하여 제2트랜지스터가 턴온되어 충전부에 충전된 직류전원이 저항을 통해 램프로 제공되므로써, 외부로부터 교류전원이 차단되는 경우, 비상등이 점등되므로 정전시에 발생되는 혼란을 방지할 수 있도록 한 것이다.The present invention relates to an emergency light lighting device when the power is cut off, the AC power from the outside is transformed to a predetermined voltage set through the transformer, rectified by the DC power supply in the rectifier is provided to the control unit and the first transistor based on the switching signal from the control unit Is turned on to charge the DC power to the charger through the resistor. At this time, if the DC power is not provided from the rectifier, the second transistor is turned on based on the low level signal from the controller, and the DC power charged to the charger is supplied to the lamp through the resistor, whereby the AC power is cut off from the outside. Lights up so that the confusion that occurs during a power outage can be prevented.
