| 摘要 |
The present invention is characterized by using capacitive, inductive or resistive impedance to constitute the first impedance which is series connected with the second impedance constituted by parallel connecting the capacitive and inductive impedances that appears parallel resonance with the pulsed period to receive pulsed power, thereby to form a divided bidirectional power at the two ends of the first and second impedances, so as toe drive the bidirectional conducting light emitting diode.
