ABSTRACT:
A transformer6and a photocoupler5are provided to ensure insulation between a primary side circuit section10connected to an alternating current power supply2, and a secondary side circuit section20for applying a voltage to a lamp4. A detection circuit section22E, provided in the secondary side circuit section20, detects an output voltage and an output current of the lamp4to detect a deviation from a predetermined power. A signal corresponding to the deviation, which has been detected by the detection circuit section22E, is transmitted to the primary side circuit section10via the photocoupler5provided between the primary side circuit section10and the secondary side circuit section20. A switching control section13, provided in the primary side circuit section10, carries out switching control for constant power lighting based on the signal transmitted from the photocoupler5.
