Abstract

본 발명은 형광등 제어 회로는 안정기(12)와, 형광등(14), 전자식 스타터 (15) 및, 상기 형광등(14)과 안정기(12) 사이에 접속된 스위치(13)를 포함하여 구성되어, 상기 안정기(12)에서 발생되는 역기전력 서지가 전자식 스타터(15)로 인가되는 것을 차단함으로써 상기 안정기(12)의 역기전력 서치에 의해 스타터(15)가 손상되는 것을 방지할 수 있는 것이다.According to the present invention, the fluorescent lamp control circuit includes a ballast 12, a fluorescent lamp 14, an electronic starter 15, and a switch 13 connected between the fluorescent lamp 14 and the ballast 12. By preventing the back electromotive force surge generated from the ballast 12 from being applied to the electronic starter 15, the starter 15 may be prevented from being damaged by the counter electromotive force search of the ballast 12.
