LIGHTING CONTROL SYSTEM AND LIGHTING CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a lighting control system and a lighting control method for making illuminance at a target part into target illuminance by easy configurations and control procedures even at a state where the lighting control system has various elements (external factors) which affect illuminance of a lighting apparatus.SOLUTION: A lighting control system 1 controls brightness of respective lighting apparatuses L1-L9, estimates insulation degrees of the respective lighting apparatuses L1-L9 to respective illuminance sensors S1-S4 on the basis of a difference between measured illuminance by the respective illuminance sensors S1-S4 and predicted illuminance at positions of the respective illuminance sensors S1-S4 predicted by a controller 10 before the measured illuminance is input, updates the predicted illuminance at the positions of the respective illuminance sensors S1-S4 on the basis of the estimated insulation degrees, and approximates the measured illuminance by the respective illuminance sensors S1-S4 to preset target illuminance by controlling brightness of the respective lighting apparatuses L1-L9 so that the updated predicted illuminance approaches the preset target illuminance.
