LIGHTING CONTROL SYSTEM AND MANAGEMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a lighting system and a management system in which an integrated monitoring device is prevented from an increase of load even if the scale of the system becomes large, disusing any integral monitoring system of high cost.

SOLUTION: The management system is constructed by connecting to a network a lighting sub-system 2 including a lighting device 21 and a lighting controller 20, an air-conditioning sub-system 3 including an air-conditioning device 31 and an air-conditioning controller 30, and the integrated monitoring system 1 equipped with a power consumption monitoring part 12 monitoring power consumed at load devices in the sub-systems and giving controllers in the sub-systems instruction to reduce the power if the power consumption under monitoring needs to be reduced. When the controller receives the instruction to reduce the power from the integrated monitoring system 1, the controller determines a load output level lower than at present, and controls the sub-system to which it belongs to operate at the above load output.
