The lighting fixture 11 is attached to a hooking ceiling (not shown) provided on the ceiling surface 1 with a fixture fixing portion / power supply connecting portion 19 arranged at the center of the housing 13.
Thereby, as for the lighting fixture 11, the fixture fixing part and power supply connection part 19 are mechanically fixed to a hook ceiling, and the lighting circuit part 15 is electrically connected to an external circuit.

As shown in FIG. 2, in the lighting fixture 11, the LED unit 16 is arranged in a square shape so as to surround the casing 13.
The LED unit 16 includes two systems of light emitting units including one LED unit 21 having a plurality of first type LED elements 20 and the other LED unit 23 having a plurality of second type LED elements 22.
The first type LED elements 20 and the second type LED elements 22 are alternately arranged.
The LED unit 16 may be a light emitting unit to which an organic EL, a fluorescent lamp, an incandescent lamp, or the like is applied instead of the LED element 20 and the LED element 22.

In the luminaire 11, the nightlight 24 is disposed at the center of the housing 13, and the light receiving element 26 mounted on the circuit board 25 included in the lighting circuit portion 15 is disposed at a position away from the nightlight 24.
The light receiving element 26 receives an infrared remote control signal through a hole 27 formed in the diffusion cover 17.
The sensor part 18 is arrange | positioned at the side edge part of the cover 14 so that the light from the LED element 20 and the LED element 22 may not enter directly.
For example, in a living room of a house, the luminaire 11 automatically adjusts light according to external light so that the average illuminance of an irradiated surface such as a floor surface or a desk surface is kept almost constant and energy saving is possible. It has a function.

The remote controller 12 transmits an infrared remote control signal from the infrared LED 29 when one of the plurality of operation buttons 28 is pressed.
When the infrared remote control signal is received by the light receiving element 26 of the lighting fixture 11, the lighting circuit unit 15 performs processing to execute a predetermined remote control mode.
Here, the remote control mode is lighting, dimming, lighting the nightlight, raising the dimming level, lowering the dimming level, turning off, starting the sensor control function, and setting the target value.
As a signal (remote control signal) transmitted by the remote controller 12, a weak radio, a specific low power radio, or the like can be applied instead of infrared rays.

In the lighting circuit unit 15, the sensor unit 18 outputs a current corresponding to the amount of incident light to the lighting circuit unit 15 by a brightness sensor (not shown) such as a built-in photodiode.
The current of the brightness sensor is converted into a voltage by a load resistor connected to the output terminal, and input to the analog input terminal of the microcomputer 35 of the control unit 33 as a sensor voltage value (brightness detection signal).

  The lighting circuit unit 15 performs lighting control of the main illumination and the nightlight 24 by the LED unit 16 in each of the remote control mode and the sensor control mode. Processing in each mode is performed by executing a program in the microcomputer 35 of the lighting circuit unit 15. The remote control mode includes a dimming mode (remote control dimming mode) for performing dimming control and an unlit mode (remote control unlit mode) for performing extinction control. .
