Abstract

See full text

An apparatus can include: a bleeder circuit coupled to a DC bus of an LED driver having a silicon-controlled dimmer, where the bleeder circuit is controlled to discharge a current of the DC bus; a controller configured to control the bleeder circuit to discharge the DC bus at a first current after detecting a transition in a voltage of the DC bus; and the controller being configured to control the bleeder circuit to discharge the DC bus at a second current until the DC bus voltage rises to a predetermined load driving voltage, where the second current is less than the first current.
