[Object] To provide an illumination fixture capable of reducing power loss and improving convenience of a lighting control operation.
[Means for Settlement] There are provided a plurality of light source parts 1 each including a light-emitting diode 10, a triac TR1 serially connected to a commercial power source AC1, a dimmer 2 for controlling the triac TR1 to make a conduction angle of a power source voltage of the commercial power source AC1 variable, and a current adjusting part 3 for keeping a holding current flowing through the triac TR1 to be a certain value or larger in a conductive period of the triac TR1, and the current adjusting part 3 includes a resistor R13 that is connected to each of the light source parts 1 in parallel when the power source voltage of the commercial power source AC1 falls below a predetermined threshold value, and is released in connection to each of the light source parts 1 when the power source voltage of the commercial power source AC1 exceeds the predetermined threshold value, and a signal outputting part 30 for outputting a signal to an external device according to an input current I1 inputted to the current adjusting part 3.
