Zusammenfassung:	A luminaire according to one embodiment includes a DC power supply circuit (12), a switching power supply (13), and a lighting load (11). The DC power supply circuit (12) converts an AC voltage controlled in phase to a DC voltage. The switching power supply (13) is connected to the DC power supply circuit (12), and is controlled so that an input current becomes a constant current. The lighting load (11) is connected as a load circuit of the switching power supply (13) .
