Abstract:
The present invention uses series connected capacitive impedance and inductive impedance, whereof the inherent series resonance and the frequency of the bi-directional power can produce series resonance, thereby the bi-directional divided power being generated at the two ends of the capacitive impedance and inductive impedance is rectified to output DC power to drive the uni-directional light emitting diode.
