ABSTRACT:
The present invention is disclosed by that the series connected capacitive impedance and inductive impedance are powered by a pulsed power, thereby to produce the bi-directional divided power in series resonance at each impedance, and be rectified by a rectifier device to provide DC power output to drive the unidirectional conducting light emitting diode.
