Claim 0:
1. A high-efficiency light-emitting diode (LED) driving circuit, comprising:
a rectifying module connected to a power source in order to output a driving current;
a power converting module connected to the rectifying module and a load, wherein the load comprises a plurality of LEDs and the power converting module comprises a controller; and
a power supplying module comprising a resistor;
wherein a power source input pin of the controller is connected to one end of the resistor and another end of the resistor is connected to a connecting point via the power supplying module, and the connecting point is disposed between two of the LEDs, wherein when the driving current reaches the load, a part of the LEDs are driven by the driving current, and then the driving current is divided into a first branch current and a second branch current when the driving current reaches the connecting point, wherein the first branch current drives another part of the LEDs, and the second branch current passes through the resistor in order to drive the controller via the power supplying module and the power source input pin of the controller.
