Claim 5:
6. A high-efficiency LED lighting device, 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 comprising a controller; and
a load connected to the power converting module and comprising a plurality of LEDs; 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 of the load 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 of the load LD, 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.
