    • 【課題】安定的に位相調光制御を行うことができる点灯装置、調光器および照明装置を提供する。【解決手段】点灯装置200は、トライアック調光器100と接続する。点灯回路230は、発光素子LEDを備える光源ユニット300と接続し、トライアック調光器100からの電源電圧で生成した電流を発光素子LEDに供給する。バイパス回路220は、トライアック調光器100と点灯回路230との間に介在する。バイパス回路220は、トライアック調光器100の出力電圧が所定値以下であるときに、トライアック調光器100の出力を点灯回路230からバイパスさせてトライアック106の出力電流を保持する。トライアック調光器100が出力電圧を出力するときに保持電流不足によってトライアック106がオフになるという問題を抑制し、トライアック調光器100の出力が不安定になるといった不具合がなくなる。従って、トライアック調光器100を安定的に動作させることができる。【選択図】図1
