Abstract

複数の入力状態を監視して共通のコイルもしくはスイッチ素子を用いて出力の変更を実現することにより点灯装置の小型化・低コスト化を実現する。異なるモードで入力されるグランド共通かつ略同電位のＤＣ電源を複数受け、複数の負荷を動作させる電力変換装置において、複数のＤＣ電源の入力状態に応じて、それぞれの負荷を動作させ、かつ少なくとも共通のスイッチ素子もしくはコイルを介して複数の負荷へ電力を供給する。第１のＤＣ電源は車両のすれ違いビームを点灯させるスイッチを介して供給される電源、第２のＤＣ電源は車両のイグニッションに連動して供給される電源とする。第１の負荷は車両用の前照灯、第２の負荷は車両の昼間点灯用のサイン灯とする。
