Description

형광등 점등회로Fluorescent lamp lighting circuit

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1 도는 본 발명의 전체회로도.1 is an overall circuit diagram of the present invention.

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 정류회로 3 : 스위칭회로1: rectification circuit 3: switching circuit

5 : 형광등회로 7 : 타이머회로5: fluorescent light circuit 7: timer circuit

Claims (1)

정류회로(1), 스위칭회로(3) 및 형광등회로(5)로 구성된 형광등점등회로에 있어서, 형광등회로(5)에 콘덴서(79) 및 코일(81)과 병렬로 릴레이(RLY)에 의해 제어되는 접점(b)를 형성시키고, 릴레이(RLY)를 트랜지스터(55)에 의해 스위칭되도록 하되, 콘덴서(43)의 충전에 따라 트랜지스터(49)가 도통되게 하고 트랜지스터(49)의 도통으로 OFF되는 트랜지스터(51)에 의해 트랜지스터(55)가 OFF되어 릴레이(RLY)가 구동을 정지하여 접점(b)이 ON되도록 형성시킨 타이머회로(7)를 부가하여서된 형광등 점등회로.In the fluorescent lamp circuit consisting of the rectifier circuit 1, the switching circuit 3 and the fluorescent lamp circuit 5, the fluorescent lamp circuit 5 is controlled by a relay RLY in parallel with the capacitor 79 and the coil 81. A transistor b to be formed, and the relay RLY is switched by the transistor 55, but the transistor 49 is turned on as the capacitor 43 is charged, and the transistor is turned off by the conduction of the transistor 49. A fluorescent lamp lighting circuit is added by adding a timer circuit 7 in which the transistor 55 is turned off by the 51 and the relay RLY stops driving and the contact b is turned on. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
