The present invention is a lighting control system including at least one
local device and a plurality of lighting devices. The communication
transmission medium between the local device and the lighting devices is
provided with directional characteristics, and the lighting devices are
selected and designated, as needed, using ID information. A designated
lighting device is lighted up and performs light intensity setting. A
judgment is carried out as to whether or not the relation between an
illumination at a desired position and a target illumination satisfies a
predetermined condition, and causes the illumination at the desired
position to approach the target illumination by letting the plurality of
lighting devices successively perform a procedure of
increasing/decreasing their respective light intensities based on a
result of the judgment. With such a lighting control system, it is
possible to let a part of the whole lighting devices, for example, the
necessary lighting devices perform control, in particular, in an
environment in which numerous lighting devices are installed, thereby
making it possible to shorten the control time and reducing a waste of
illumination.
