A driving circuit c, a power transformer d for stepping down the AC power supply E, a timer circuit T1 using the lighting signal T as a starting signal, and a relay RY1 using the output of the timer circuit T1 as a power supply for the driving coil. The timer circuit T1 is also operated at the same time as the lighting signal and the lighting switch, and during a fixed period, that is, a period of t2 shown in FIG.
A voltage is supplied to the drive coil of the relay RY1 to connect the secondary side of the power transformer d to the incandescent lamp load L and the switch element b. In this period t2, a time sufficient for the filament of the incandescent lamp load to warm up is set assuming a load to be connected in advance.
