Claims (3)
- 交流電源電圧を整流した直流電圧を昇圧する昇圧チョッパ回路と、この昇圧チョッパ回路の出力を高周波交流電圧に変換するインバータ回路とを具備し、前記インバータ回路の出力によって放電ランプを点灯させる放電ランプ点灯装置において、
前記昇圧チョッパ回路および前記インバータ回路を制御するための共通の制御用電源を前記インバータ回路の出力のみから得ており、前記インバータ回路が停止をしている場合には前記昇圧チョッパ回路も停止し、かつ、起動時は前記インバータ回路が前記昇圧チョッパ回路よりも先に動作を開始するように制御することを特徴とする放電ランプ点灯装置。 - 前記放電ランプを消灯させる消灯信号が入力されると発振停止手段が前記チョッパ回路および前記インバータ回路を停止させることを特徴とする請求項1記載の放電ランプ点灯装置。
- 請求項1または2記載の放電ランプ点灯装置を器具本体に収納し、この器具本体に取り付けられる放電ランプを点灯させることを特徴とした照明器具。
