<P>PROBLEM TO BE SOLVED: To provide a lighting fixture capable of closely arranging a plurality of sets and achieving energy saving by controlling each lighting fixture when illuminating on the basis of signals from a remote controller or a human sensor. <P>SOLUTION: In the lighting fixture, when driving a light-emitting section 22 with power supplied through a power supply terminal 21 connected with a commercial power source 51, signal intensity of a non-contact signal 31 received by a receiving section 24 and transmitted from the outside of a fixture body 20 and signal intensity of a signal transmitted from the other lighting fixture 53 arranged closely through a signal line 54 are memorized in a memory section 25. A signal processing section 26 determines a power value to be supplied to the light-emitting section 22 on the basis of signal intensity, and transmits the determined power value to the other lighting fixture 53 through the signal line 54 connected with a signal terminal 23, and receives a power value from the other lighting fixture 53. A power supply control section 27 drives the light-emitting section 22 by supplying power to the light-emitting section 22 on the basis of the determined power value. <P>COPYRIGHT: (C)2011,JPO&INPIT |
