An illumination control system for controlling supply of electric power to a plurality of lighting apparatuses each of which adjusts a lighting state of a corresponding one of a plurality of light sources, the illumination control system comprising:
- a manipulation detector;
- and
- an electric power controller,
- the manipulation detector being configured to detect an ON manipulation by a user and an OFF manipulation by a user,
- the electric power controller being configured to
- stop the supply of the electric power to the plurality of lighting apparatuses when the OFF manipulation is detected,
- start the supply of the electric power to the plurality of lighting apparatuses when the ON manipulation is detected after detection of the OFF manipulation and before a first timing, or when the ON manipulation is detected at or after a second timing, and
- start the supply of the electric power to the plurality of lighting apparatuses at or after the second timing when the ON manipulation is detected at or after the first timing and before the second timing,
- the first timing being a timing at which a threshold time which is predetermined has elapsed since the detection of the OFF manipulation,
- the second timing being a timing at which a predetermined forced interruption time has elapsed since the first timing.
