LED DRIVING CIRCUIT FOR AC DRIVING AND DIMMING BASED ON CONSTANT CURRENT OF SINE WAVE

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.
