SELECTIVELY ACTIVATED RAPID START/BLEEDER CIRCUIT FOR SOLID STATE LIGHTING SYSTEM

摘要

A device controls current drawn by a solid state lighting (SSL) fixture, including a power converter and an SSL load. The device includes a rapid start/bleeder circuit having a selectable low impedance path, configured to be temporarily activated to form a low impedance connection between a voltage rectifier and the power converter providing power to the SSL load. The low impedance path is temporarily activated during a start-up period to charge the power converter and during times other than the start-up period based on detected improper operation of the SSL fixture.
