Abstract
A capacitively ballasted low voltage lamp utilizing a main capacitor connected electrically in series with the lamp, across an alternating current source, and one or more auxiliary capacitors that can be connected electrically across the main capacitor by switching means for one or more source waveform cycles. Each switching means comprises a unidirectional conductive device electrically connected in parallel with an active switching device. The minimum lamp current is established by the main capacitor, with additional lamp current flowing through one or more auxiliary capacitors during a source waveform cycle or integral multiples thereof.
