<P>PROBLEM TO BE SOLVED: To provide a lighting control system which can take control of appropriate brightness according to an actual use circumstance. <P>SOLUTION: A lighting control system comprises: at least a plurality of lighting apparatuses L; a plurality of illumination sensors S, installed in each of areas E obtained by dividing lighting space, for measuring luminous intensity of the lighting space; and a control part 2 for controlling an illumination output of each lighting apparatus on the basis of a preset value. In this lighting control system, the control part sets the preset value for each of the areas on the basis of measured values by the illumination sensors when lighting the lighting apparatuses at night, to implement control in such a way that: when one of the measured values of the illumination sensors during the day time is higher than the preset value, the illumination output of the lighting apparatus installed in its corresponding area is decreased, while when one of the measured value is lower than the preset value, the illumination output of the lighting apparatus installed in its corresponding area is increased. <P>COPYRIGHT: (C)2013,JPO&INPIT |
