<P>PROBLEM TO BE SOLVED: To provide a lighting control system that sets a target detection value based on a brightness sensor in conformity with an ambient environment thereof and performs light control on lighting equipment so that the detection value based on the brightness sensor is coincident with the target detection value, thereby performing high-precision light control matched with the ambient environment and reducing the cost. <P>SOLUTION: A master unit 2A stores the average value of target detection values based on brightness sensors 4 which are set in accordance with the ambient environments of the brightness sensors 4. The master unit 2A performs light control on each piece of lighting equipment 2 so that the average value of the detection values based on the brightness sensors 4 is substantially coincident with a pre-stored average value, so that the high-precision light control matched with the ambient environment can be performed. Furthermore, at least two brightness sensors 4 are provided in a lighting equipment group 3. Therefore, the number of the brightness sensors 4 can be reduced and thus the cost can be reduced as compared with the case where the brightness sensor 4 is secured to each of all of the lighting equipment 2 and the light control is performed on each piece of lighting equipment 2 on the basis of each measurement result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
