<P>PROBLEM TO BE SOLVED: To provide a lighting control system which can attain energy saving by reducing unnecessary power consumption. <P>SOLUTION: The lighting control system 1 comprises a plurality of lighting fixtures 10 (10a-10i) which are set, respectively, in regions Aa-Ai. Each lighting fixture 10 is provided with an image sensor 13 which captures the image of an illumination region of the lighting fixture, and a control unit 12 which controls the lighting state of a light source 11 based on the image captured by the image sensor 13. A lighting controller 18 in the control unit 12 detects intensity change in a region where an intensity change detector 17 in the control unit 12 is contiguous to other lighting fixture 10, and sets the lighting state of the light source 11 in a first lighting state when a human body detector 16 in the control unit 12 does not detects existence of a person. <P>COPYRIGHT: (C)2012,JPO&INPIT |
