Abstract: To stably illuminate an LED lamp even when an internally-excited electronic transformer is used in the power supply circuit, the full wave of the AC voltage supplied from the power supply circuit is rectified using a current rectifying circuit. When the power supply starts, current flows into a start-assist circuit for a specific period of time. Subsequently, when the fixed current load circuit begins operating, the current will flow into the fixed current load circuit. When the current flows into the LED driver, operation of the fixed current load circuit is stopped by a current-stopping circuit. Because the current flows into the lamp-lighting circuit across the entire voltage output even when an internally-excited electronic transformer is used in the power supply circuit, operation of the internally-excited electronic transformer will not stop and will not become unstable. When the LED is not connected, the fixed current load circuit is stopped.
