摘要： An AC direct driver lighting system is disclosed. According to one embodiment, the AC direct driver lighting system includes a plurality of LED groups serially connected to an AC power source, and an AC driver comprising a plurality of current sinks. Each of the plurality of current sinks is connected between a respective LED group of the plurality of LED groups and a ground. The AC direct driver lighting system further includes a valley fill circuit coupled to a target LED group of the plurality of LED groups. The valley fill circuit charges from the AC power source and supplies electrical power to the target LED group via a current path established between the AC power source and the ground via at least one of the plurality of current sinks.
