PROBLEM TO BE SOLVED: To perform illuminance control suited to a present user's preference in every spot in space even if lighting fixtures illuminate the same space.SOLUTION: An illuminance control device 20 includes: an illuminance matrix storage section 22 for storing beforehand an illuminance matrix H whose matrix components are each an illuminance at one of a plurality of lattice points where a plurality of lighting fixtures L are each lit at a lighting rate of 100%; an input section 10 for receiving the input of one of the plurality of lattice points where the illuminance is to be controlled and a desired illuminance at the lattice point; a setting illuminance vector generation section 21 for generating a setting illuminance distribution vector on the basis of the input lattice point and the desired illuminance for the lattice point; a lighting rate vector calculation section 23 for calculating a lighting rate vector of each of the plurality of lighting fixtures L on the basis of the illuminance matrix H and the setting illuminance distribution vector; and a lighting fixture control section 24 for controlling the lighting of the plurality of lighting fixtures L on the basis of the lighting rate of each of the plurality of lighting fixtures L. |
