ILLUMINATION CONTROL SYSTEM, ILLUMINATION CONTROL METHOD, AND PROGRAM

To provide an illumination control system capable of easily providing an illumination environment suitable for an irradiated area.SOLUTION: An illumination control system 100 includes a first acquisition unit 11, a processing unit 12, and a control unit 13. The first acquisition unit 11 acquires first information relevant to a color of light by first illumination (first illumination load 21) that emits light to an irradiated area. The processing unit 12 determines the chromaticity of light by second illumination (second illumination load 22) based on the first information acquired by the first acquisition unit 11 so that the chromaticity of the irradiated area is within a specified range. The irradiated area is an area that has multiple light sources 220 that emit light of different colors, and is irradiated with both of the light from the second illumination which has a concentrated light distribution characteristic and the light by the first illumination. The control unit 13 controls the second illumination to emit light with the chromaticity determined by the processing unit 12.SELECTED DRAWING: Figure 1 【課題】被照射領域に適した照明環境を提供しやすくすること。【解決手段】照明制御システム１００は、第１取得部１１と、処理部１２と、制御部１３と、を備える。第１取得部１１は、被照射領域に光を放射する第１照明（第１照明負荷２１）による光の色に関する第１情報を取得する。処理部１２は、被照射領域の色度が所定の範囲に含まれるように、第１取得部１１で取得した第１情報に基づいて、第２照明（第２照明負荷２２）による光の色度を決定する。被照射領域は、互いに異なる色の光を放射する複数の光源２２０を有し、かつ、集光形の配光特性を有する第２照明による光、及び第１照明による光の両方が照射される領域である。制御部１３は、処理部１２で決定した色度の光を放射するように第２照明を制御する。【選択図】図１
