Abstract
Description
Claims (3)
- 메인전원과 상기 메인전원으로부터 충전된 축전지에 의한 비상전원에 의하여 구동되는 램프의 안정기회로에 있어서:상기 메인 전원을 정류하는 정류부;상기 정류부에서 정류된 전원을 상기 램프의 동작전원으로 변환하여 공급하는 정상 전압 발생부;상기 램프에 흐르는 전류를 감지하는 감지부;상기 축전지의 전원을 상기 램프의 동작전원으로 변환시키는 비상전압 발생부;상기 메인 전원을 소정의 직류 전압으로 변환하는 전압변환부;상기 메인 전원에 전원이 공급되지 않는 경우에 동작되는 제1릴레이;상기 제1릴레이에 의하여 상기 램프에 공급되는 전원을 상기 정상 전압 발생부로부터 상기 비상전압 발생부로 절체하기 위한 절체 스위치;상기 축전지와 상기 비상전압 발생부 사이에 설치되는 보호스위치;상기 전압변환부의 출력전압과 상기 감지부에 흐르는 전류에 비례한 출력전압이 기설정된 전압보다 낮은 경우에 상기 보호스위치를 동작시켜 상기 축전지로부터 상기 비상전압 발생부에 전원이 공급되는 전원을 차단하는 무부하 보호회로를 포함하는 것을 특징으로 하는 램프 안정기 회로.
- 제 1 항에 있어서, 상기 무부하 보호회로는상기 보호스위치를 동작시키는 제2릴레이;비반전단자에 기준전압 설정회로가 연결되고, 반전단자에 상기 감지부에 흐르는 전류에 비례하는 전압과 상기 전압변환부의 출력전압이 공통으로 인가되며, 출력단자에 상기 제2릴레이를 구동시키는 구동회로가 연결되는 비교기를 포함하고, 상기 비교기는 상기 비반전단자의 전압이 상기 반전단자의 전압보다 높은 경우에 동작출력을 발생시키고, 상기 보호스위치는 상기 축전지로부터 상기 비상전압 발생부에 공급되는 전원을 차단시키는 것을 특징으로 하는 램프의 안정기회로.
- 제 2 항에 있어서, 상기 무부하 보호회로의 상기 비반전단자의 입력이 0V인 경우에 상기 동작출력을 발생시키는 것을 특징으로 하는 램프의 안정기 회로.
