Abstract (en)

[origin: WO2012007798A2] Disclosed are a method and apparatus for controlling bleed current, to provide the bleed current until ringing of input current at a dimmer has ceased in order to prevent misfiring of a dimmer and flicker of the light source. The return path current to the dimmer is boosted by the bleed current to be at a level greater than the holding current of the dimmer. As a result, the load current of the dimmer is increased to a sufficient minimum so that the dimmer can operate properly.
