Claims (7)

전자식 형광등용 안정기의 동작이 기존의 하프브릿지(HALF BRIDGE)방식 인버터(INVERTER)회로에 전원 공급시 동작지연 회로(1)의 작동으로 잠깐동안 지연 됐다가 히터 전압 공급회로(2)의 작동으로 형광등의 히터는 가열되고 주파수 변환회로(3)의 작동으로 형광등이 약 60%정도 점등하여 서서히 밝혀져 수초후 완전히 점등하고 형광등이 완전히 점등한후 히터 전압이 차단되고 전압 궤환회로(4)의 작동으로 파고율을 줄여 주고 과전압 보호회로(5), 과전류 보호회로(6)의 동작으로 전체 회로를 보호하게끔 설계된 각 회로 및 위와 같이 구성된 전자식 형광등용 안정기.The operation of the electronic fluorescent ballast is delayed for a short time by the operation of the operation delay circuit (1) when power is supplied to the existing half-bridge type inverter circuit, and then the fluorescent lamp is operated by the operation of the heater voltage supply circuit (2). Heater is heated and the fluorescent lamp is turned on by the operation of frequency conversion circuit (3) and turns on gradually by about 60%. After a few seconds, it turns on completely and the heater voltage is cut off after the fluorescent lamp is turned on completely. Ballasts for electronic fluorescent lamps as described above and each circuit designed to reduce the voltage and protect the entire circuit by the operation of the overvoltage protection circuit (5) and the overcurrent protection circuit (6). 제1항에 있어서, 동작 지연 회로(별첨 1)과 같이 구성된 회로.A circuit according to claim 1, configured as an operation delay circuit (Annex 1). 제2항에 있어서, 히터 전압 공급회로(별첨 2)와 같이 구성된 회로.The circuit according to claim 2, configured as a heater voltage supply circuit (Annex 2). 제3항에 있어서, 주파수 변환회로(별첨 3)과 같이 구성된 회로.4. A circuit according to claim 3, configured as a frequency conversion circuit (Annex 3). 제4항에 있어서, 전압 궤환회로(별첨4)와 같이 구성된 회로.The circuit according to claim 4, configured as a voltage feedback circuit (Appendix 4). 제5항에 있어서, 과전압 보호회로(별첨 5)와 같이 구성된 회로.The circuit according to claim 5, configured as an overvoltage protection circuit (Annex 5). 제6항에 있어서, 과전류 보호회로(별첨 6)과 같이 구성된 회로.The circuit according to claim 6, configured as an overcurrent protection circuit (Annex 6). ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
