Claim Text:
1. An alternating current (AC) lighting system comprising: an LED load; a rectifier configured to receive AC voltage from an AC power source and generate rectified AC voltage by rectifying the AC voltage from the AC power source; an LED driver configured to drive the LED load; and a surge protection circuit connected to the AC power source and the rectifier; and a post surge protection circuit connected to the rectifier, the LED driver, and the LED load, respectively, wherein the post surge protection circuit is configured to receive the rectified AC voltage from the rectifier and provide a first voltage to the LED load via a direct path to the LED load and a second voltage to the LED driver, wherein the post surge protection circuit comprises at least one current limiting circuit that is capable of limiting first current flowing from the rectifier to the LED load via the direct path and second current flowing from the rectifier to the LED driver.
