본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는, 본 발명의 방전램프 점등장치의 1실시예를 나타내는 회로도.
제2도는, 제1도의 동작을 나타내는 그래프이다.
* 도면의 주요부분에 대한 부호의 설명
1 : 가변 안정화 전원 2 : 인버어터 회로
3 : 방전램프 4 : 온도검지회로

Claims (2)

  1. 방전램프(3)의 램프 전류값을 적어도 2단계 이상 설정 가능한 전원수단과, 온도를 검출하는 온도 검출 수단을 구비하고, 이 온도 검출수단으로 온도가 소정이하로 되며, 또한 상기 전원 수단에 의하여 램프 전류값이 소정값이하로 설정되어 있는 경우, 상기 전원 수단에 의하여 설정되는 램프 전류의 하한값을 변화시키는 것을 특징으로 한 방전램프 점등장치.
  2. 제1항에 있어서, 전원수단에 의하여 설정되는 램프 전류의 하한값의 변화는, 하한값을 높게 변화시키는 것을 특징으로 한 방전램프 점등장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
