1. An illumination control device which controls an illumination light source, the illumination control device comprising:
- a motion detector; and
a control unit configured to perform control of illuminance, color, or distribution of light of the illumination light source based on an ON period or an OFF period, the ON period being a period during which a person is detected by the motion detector, and the OFF period being a period during which no person is detected by the motion detector.

16. An illumination system comprising
a plurality of illumination devices including a master illumination device and a plurality of slave illumination devices, the master illumination device including: -
an illumination light source; a motion detector; a control unit configured to perform control of illuminance, color, or distribution of light of the illumination light source of the master illumination device based on an ON period or an OFF period, the ON period being a period during which a person is detected by the motion detector, and the OFF period being a period during which no person is detected by the motion detector; and a transmitter which wirelessly transmits, to the plurality of slave illumination devices, a control signal to allow the control unit to perform the control of the illuminance, color, or distribution of the light of the plurality of slave illumination devices, and the plurality of slave illumination devices each including; an illumination light source; and a receiver which receives the control signal wirelessly transmitted from the transmitter, wherein when the control unit performs the control to place the illuminance, color, or distribution of the light of the illumination light source of the master illumination device in a first state based on the ON period or the OFF period, the control unit is configured to perform the control to place the illuminance, color, or distribution of the light of the illumination light source of each of the slave illumination devices in the first state by causing the transmitter to transmit the control signal to the receiver of each of the slave illumination devices.
