Claims (2)

  1. 방전등(18)과, 이 방전등에 출력단자가 접속되어 방전등에 소정의 전력을 공급해서 주 점등시키는 점등회로(100)와 전술한 점등회로와 병렬적으롤 방전등에 출력단자가 접속되어 방전등이 초기 방전을 개시하고 또 전술한 점등 회로에서 방전등으로 공급되는 소정의 전력 보다도 작은 전력으로 초기 방전을 유지하는 시동 회로로 이루어지는 방전등 점등 장치에 있어서, 전술한 시동 회로의 동작에 의해 전술한 방전등의 시동후 초기방전이 유지되고 있는 사이에 전술한 점등 회로에서 소정의 전력을 전술한 방전등으로 공급하는 타이밍을 제어하는 제어회로(64)(104) (116)를 설치한 것을 특징으로 하는 방전등 점등장치.
  2. 방전등에 고 전압을 공급해서 초기 방전을 개시시키고, 초기 방전이 개시한후 주점등에 필요한 전력 보다도 작은 전력을 방전등에 공급해서 방전등의 초기 방전을 유지시키고, 초기 방전이 개시되어 유지되고 있는 동안에 점등회로에서 전술한 방전등을 주점등 시키는 소정의 전력을 공급해서 주 방전을 행하는 것을 특징으로 하는 방전등 점등방법.
