Abstract

An LED lighting system including an LED device, a power device, at least one detecting device, and at least one voltage adjusting device is provided. The power device provides a DC voltage to a high-voltage end of the LED device. When being conducted, the LED device has a cross-voltage. The detecting device is used for detecting an operation voltage of a low-voltage end of the LED device. According to the detected result of the detecting device, the voltage adjusting device adjusts at least one compensating voltage between the low-voltage end of the LED device and the ground terminal. The sum of the cross-voltage and the adjusted compensating voltage is equal to the DC voltage.
