PROBLEM TO BE SOLVED: To provide a lighting control unit 11 capable of swiftly adjusting to be consistent with control content of a schedule when restarted after system stop. SOLUTION: A control station 18 controls a lighting fixture 12 via a child station 19 according to the schedule and stores switching states of respective switches 16 during system start. When restarting after system stop due to electrical power interruption, the control station 18 calculates the control content of the lighting fixture 12 based on schedule at the current time point. Based on the calculated control content, the lighting fixture 12 is controlled to be consistent with the control content of the schedule swiftly. Then, priority is given to the switch state of the switches 16 during system start to be consistent with the artificially set control content. COPYRIGHT: (C)2008,JPO&INPIT |
