摘要： An AC lighting system for providing uniform light distribution is disclosed. According to one embodiment, the AC lighting system includes an AC driver and LED packages electrically connected to the AC driver. Each LED package includes a plurality of LED elements and is physically distributed over an illuminating surface of the AC lighting system. The AC driver has a first current sink that drives a first LED group and a second current sink that drives the first LED group and a second LED group. The first LED group includes at least one LED element from each of the LED packages, and the second LED group includes at least one LED element other that the first set of LED elements from each of the LED packages.

摘要： An AC direct driver lighting system including a surge protection circuit and a current limiting circuit is disclosed. According to one embodiment, the AC direct driver lighting system includes an LED load, a rectifier, and an LED driver configured to receive rectified AC voltage from an AC power source and drive the LED load. The AC direct driver lighting system further includes a surge protection circuit and a current limiting circuit disposed between the AC power source and the LED load. The surge protection circuit and the current limiting circuit suppress excessive current flowing through the AC direct driver lighting system.

摘要： An AC direct driver lighting system is disclosed. According to one embodiment, the AC direct driver lighting system includes an AC power source, a plurality of LED groups, and an AC driver comprising a current sink connected between the AC power source and the plurality of LED groups. The AC direct driver lighting system further includes at least one of a valley fill circuit and a load balancer circuit coupled to a target LED group of the plurality of LED groups. The valley fill circuit charges supplies electrical power to a target LED group and the load balancer circuit reduces the current flowing through the target LED group.
