PROBLEM TO BE SOLVED: To provide an illuminating fixture capable of transmitting a data signal for dimming by PLC and of performing dimming of a light-emitting element, such as an LED, without performing pulse width control.SOLUTION: In an illuminating device 10, a light-emitting current setting part 40 sets a value of a current flowing in a light-emission part 60 on the basis of an extracted data signal, and a drive part 50 controls a constant current from a light-emitting power supply part 22 according to the set value of a current. The light-emission part 60 is dimmed by applying the controlled constant current to the light-emission part 60. |
