摘要
The present invention relates to an LED driving circuit, capable of directly driving and dimming an LED with AC power of a current of a sine wave suitable for power factor regulations and harmonic regulations, driving the LED with a low AC input by using a simple circuit without increasing the number of components, and obtaining a high flicker feature by constantly maintaining the current in spite of the variation of an AC voltage.
