Energy-saving lighting control system

摘要

PPROBLEM TO BE SOLVED: To inexpensively provide a lighting control system reducing a cost of a single luminaire, reducing a construction cost by simplifying a construction for installing the luminaire, and apparently contributing to energy saving by performing a precise dimming control to reduce an effect of sensing received from a surrounding fluorescence device. PSOLUTION: A single total illumination area equipped with a large number of luminaires is divided into a plurality of unit dimming control areas, a unit dimming control area selected from the plurality of unit dimming control areas is a representative unit dimming control area, a representative illuminance sensor is arranged only in the representative unit dimming control area, and a control unit controlling illuminance of all the luminaires in the total illumination area generates a dimming signal based on an illuminance signal from the representative illuminance sensor and outputs the generated dimming signal to all the luminaires in the total illumination area, thereby unifying the illuminance of the corresponding luminaire to perform the dimming control to a set illuminance.
