Abstract
An LED driver is couple to a first LED module and a second LED module, and the LED driver includes a first power conversion module, a switch, a second power conversion module, and a control module. The control module controls the switch to conduct so as to provide a second DC voltage and a third DC voltage outputted by the first power conversion module to the first LED module. The control module controls the switch not to conduct, and controls the second power conversion module to provide a fourth DC voltage, a fifth DC voltage, and a sixth DC voltage according to the second DC voltage for providing the fourth DC voltage, the fifth DC voltage, and the sixth DC voltage to the second LED module.
