본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 램프 수명 예측 회로의 한 버젼(version)의 추가와 더불어 두개의 형광 램프에 연결된 밸러스트(ballast)수단 도시도
제2도는 본 발명의 램프 수명 예측-회로의 다른 버젼과 더불어 두개의 형광 램프에 연결된 밸러스트 수단 도시도

Claims (6)

  1. 두개의 형광 램프에 그들을 비추기 위해 파워를 제공하고, 램프의 점화전 열처리, 점화시 및 점화후 동작을 위한 파워를 제공하고, 그들이 점화하지 못하면 램프를 반복적으로 점화시키는 시도를 동작 가능하게 하는 밸러스트 수단과, 형광 램프중 적어도 하나가 점화되지 못하는 동안 소정의 시간후에 상기 램프를 점화시키는 시도를 하면서 밸러스트 수단을 중지시키는 감지 수단을 포함하고, 두개의 형광 램프 동작에 알맞는 회로 장치.
  2. 제1항에 있어서, 밸러스트 수단이 지시된 방법으로 동작할때 그들이 형광 램프에 거의 동등한 전압을 제공하고, 감지 수단은 두개의 램프중 하나의 양단에 전압이 나머지 양단에 거의 동일하지 않게 감지하고 램프를 점화하기 위한 시도를 계속하는 밸러스트 수단을 방지하기 위해 반응해서 동작하는 회로장치.
  3. 제2항에 있어서, 상기 감지 수단이 하나의 형광 램프 양단의 전압이 나머지 양단의 그것에 거의 동일하지 않게 되는 결과로써 충전되는 캐패시터를 포함하는 회로 장치.
  4. 제1항, 제2항 또는 제3항에 있어서, 감지수단이 두개의 형광 램프를 갖는 브릿지 회로를 형성하기에 알맞은 두개의 캐패시터를 포함하는 회로 장치.
  5. 제1항, 제2항, 제3항 또는 제4항에 있어서, 두개의 형광 램프가 밸러스트 수단을 갖는 회로에 연결될 수 있고 회로 장치가 회로로부터 형광 램푸중의 하나를 제거된 형광 램프 위치에서 대치 형광 램프를 회로로 삽입에 반응하는 재-시동 회로 수단을 포함함으로써 감지수단이 램프를 점화하기 위해 밸러스트 수단에게 시도를 허용하기 위해 동작하는 회로장치.
  6. 제5항에 있어서, 재-시동 회로 수단이 형광 램프의 전극을 통해 전류 흐름에 응답하는 재시도 회로를 포함하고, 재-시도 회로 수단이 램프를 통해 전류 흐름의 중지를 감지하는 재시도 회로에 응답하여 동작하는 회로장치.
