Abstract
A detector detects first information which represents sensing presence or absence of a person in an illuminated space and represents a position of the person in the illuminated space when sensing the presence, and second information representing brightness of the illuminated space. When external light enters the illuminated space, a controller receives both detected results of first information and second information and controls lighting fixtures in a lump so that the second information becomes a prescribed target value when the presence is sensed. When no external light enters the illuminated space, the controller receives a detected result of the first information and individually controls respective lighting fixtures in accordance with the first information regardless of the second information.
