Abstract
A power saving arrangement for use with a phase cut dimmer, the power saving arrangement constituted of: a power converter arranged to convert a received alternating current power signal to a direct current signal; a detector arranged to detect the presence, or absence, of the phase cut dimmer blocking a portion of an alternating current mains power sine wave from reaching the power converter; and a controllable minimum holding current circuit in communication with the received alternating current power signal, the controllable minimum holding current circuit responsive to an output of the detector, wherein in the event that the detector detects the absence of the phase cut dimmer, the controllable minimum holding current circuit is disabled such that a minimum holding current is not provided.
