The present invention uses capacitive, inductive, or resistive impedance to constitute the first impedance, and the capacitive and inductive impedances in parallel connection which will not produce parallel resonance to constituted the second impedance, and is characterized in that the first and second impedance in series connection is configured for inputting pulsed power, thereby to form a bi-directional power in decaying wave shape at the two ends of the second impedance to drive the bi-directional conducting light emitting diode.
