Abstract
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.
