Abstract
A lighting control device that controls a lighting device includes: a brightness sensor that obtains brightness information indicating a current brightness of an illuminated surface; a storage that stores a brightness target value for the illuminated surface; a controller; a receiver via which the controller receives an energy-saving signal; and a transmitter that transmits, to the lighting device, a control signal generated by the controller. When the energy-saving signal is not being received, the controller determines a dimming rate for the lighting device based on the brightness target value and the brightness information. When the energy-saving signal is being received, the controller determines an energy-saving brightness target value smaller than the brightness target value by multiplying the brightness target value by a predetermined rate and determines an energy-saving dimming rate for the lighting device based on the energy-saving brightness target value and the brightness information.
