<p><P>PROBLEM TO BE SOLVED: To provide an indoor lighting system to obtain almost uniform illuminance with a comparatively simple structure. <P>SOLUTION: In the indoor lighting system 10, a control unit 20 performs light control including light quantity-increasing control, light quantity-reducing control, and light putting-out control to a group of illumination units 30 in the order that among a group of illuminating units 30, an illumination unit 30a located at the window side closest to a window W is controlled first, and the illumination unit 30d located at the back wall side furthest from the window W is controlled last. Accordingly, since the illumination unit 30a on the window side which most easily receives influence of outside light Lz is controlled with top priority, almost uniform illuminance can be efficiently obtained, compared with the case of controlling light without determining the order of such light control, and the case of controlling light of the illumination unit 30d on the wall side which is most difficult to receive influence of outside light Lz. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
