Abstract
Description
Claims (1)
- 입력측에 교류전원을 접속하고, 그 출력전력을 제어하여 복수의 필라멘트 램프를 점등시키는 필라멘트 램프 점등장치에 있어서,상기 복수의 필라멘트 램프에 대응하여 각각 형성되고, 상기 교류전원으로부터 공급되는 정현파 전류 혹은 그 전파정류된 입력전류를 스위칭하는 스위칭 소자를 구비한 점등 제어회로와,상기 스위칭 소자의 ON/OFF 신호를 출력하는 제어부를 구비하고,상기 점등 제어회로는 상기 스위칭 소자가 ON일 때, 입력전류를 필라멘트 램프로 공급하고, 스위칭 소자가 OFF일 때, 해당 필라멘트 램프와 직렬로 접속된 인덕턴스 요소에 축적된 에너지에 의해 필라멘트 램프로 지속적으로 전류를 흐르게 하고, 이후, 상기 ON/OFF를 반복함으로써, 전체로서 입력전류파형과 대략 동일한 형상의 출력전류를 필라멘트 램프에 공급하고,상기 제어부는 각 점등 제어회로의 스위칭 소자의 ON/OFF신호의 듀티를 변화시킴으로써, 상기 출력전류의 피크값을 변화시킴과 아울러, 상기 각 점등 제어회로에 타이밍을 겹치지 않게 하여 ON/OFF 신호를 공급하는 것을 특징으로 하는 필라멘트 램프 점등장치.
