<P>PROBLEM TO BE SOLVED: To suppress wasteful energy consumption to appropriately reduce an energy load to achieve energy saving, by, when a person only passes through, determining that the person enters and passes through. <P>SOLUTION: A lighting control system comprises: lighting devices each having a lighting region as a unit zone obtained by dividing a room; high-accuracy human body detecting sensors each using the unit zone as a detecting region and disposed in each unit zone; and a controller for controlling a light control output of the respective lighting devices. The controller performs control for gently continuously increasing the light control output of the lighting device in the lighting region receiving a signal indicating staying of a person from the high-accuracy human body detecting sensor until a predetermined time or predetermined illuminance is reached, within a region of a change ratio in brightness preventing workers in an office from perceiving a variation in brightness, and after the predetermined time or predetermined illuminance is reached, rapidly increasing the light control output to appropriate illuminance suitable for working. <P>COPYRIGHT: (C)2013,JPO&INPIT |
