Abstract

본 발명은 블록킹(Blocking) 발진회로를 사용한 전자식 형광등 점등장치에 있어서 발진코일을 트로이덜 코어(troidal core)에 감고 발진주파수를 변화시킬 수 있는 수단에 의해 코일의 2차측 램프 평균 전압과 관전류를 변화시킴으로써 광범위한 범위에 걸쳐 안정된 밝기 조절을 실현할 수 있는 수단을 제공하고, 또한 형광램프의 접속이 불량하거나, 빠졌을 경우 발진기능을 정지시켜 무부하 전류를 차단함으로써 점등장치 회로를 보호할 수 있는 기능을 갖춘 형광등 조광 안정기에 관한 것이다.The present invention is to change the average voltage and tube current of the secondary side of the coil by means of winding the oscillation coil to a troidal core and changing the oscillation frequency in an electronic fluorescent lamp lighting device using a blocking oscillation circuit. By providing a means to realize stable brightness control over a wide range, and also to protect the lighting device circuit by stopping the no-load current by stopping the oscillation function when the fluorescent lamp is connected or disconnected. It relates to a light control ballast.
