ABSTRACT:
An electronic power-saving power control circuit for connection between a single-phase power supply and a lighting fixture to control the output of power supply to the lighting fixture is disclosed to include a CPU (central processing unit), a power voltage detector, a silicon controlled semiconductor circuit, a current phase detector, a trigger circuit, a resistor, a current detector, and a DC power supply circuit. The electronic power-saving power control circuit saves the consumption of power supply by dropping the voltage without affecting normal working of the lighting fixture at the load and, achieves an overcurrent protection.
