ABSTRACT:
The present invention transfers AC electric power to mutually series connected resistive impedance components, inductive impedance or capacitive impedance to divide the voltage of the power source, whereby the divided power of each impedance is rectified by the rectifier device to be the uni-directional DV power for driving the unidirectional light emitting diode.
