Abstract
Description
低電圧ランプ110は、電子トランスにより生成されるトランス出力信号107を検出すると前記スイッチを活性化することができる。前記スイッチは、前記反応性負荷を前記トランス出力に結合することができる。前記反応性負荷は、トランス106から引き出される当該電流が前記電子トランスに関連している振動電流に等しい又はこれを超えることを保証するのに必要な最小の電流を引き出すことができる。少なくとも1つの実施例において、前記反応性負荷は、前記スイッチが活性化される場合、トランス106の出力ポートの両端に接続されるインダクタ又は誘導要素を含むことができる。このような態様において、低電圧ランプ110は、電子トランスが検出される場合に前記トランス出力に接続される選択可能な反応性負荷を含んでいる。逆に、低電圧ランプ110は、前記磁気トランスが検出される場合に前記反応性負荷を切り離すことができる。
