Abstract
A lighting system includes: a demand controller which outputs a demand signal; a control panel which suspends supply of power from a power line for a first predetermined time period by controlling switches based on the demand signal; and a light fixture which includes a light emitter, a detector, an occupancy sensor, and a controller which, if the detector detects that the power being supplied to the light fixture emitting light in a first illumination state is suspended for the first predetermined time period: causes the light fixture to emit light in a second illumination state dimmer than the first illumination state if the occupancy sensor has sensed a person; and causes the light emitter to emit light in a third illumination state dimmer than the second illumination state if the occupancy sensor has sensed no one.
