Lighting load management system for lighting systems having multiple power circuits
First Claim
1. A lighting control process for a space equipped with multiple lamps for illuminating the space and multiple power circuits for supplying power to different groups of said lamps, said process comprising:
- storing information relating to the past illumination of the lamps in each of said different groups,detecting conditions or events that indicate that increased illumination of said space by said lamps is needed,producing a first control signal in response to the detection of a condition or event that indicates that increased illumination of said space by said lamps is needed, andin response to said first control signal, supplying power to at least one of said power circuits, which is selected on the basis of said stored information, to turn on the group of lamps receiving electrical power from that power circuit.

Abstract
A lighting control system is provided for a space that is equipped with multiple lamps for illuminating the space and multiple power circuits for supplying power to different groups of the lamps. The control system stores information relating to the past illumination of the lamps in each of the different groups. The system detects conditions or events that indicate that increased illumination of the space by the lamps is needed, and produces a control signal in response to the detection of a condition or event that indicates that increased illumination of the space by the lamps is needed. In response to the control signal, the system supplies power to at least one of the power circuits, which is selected on the basis of the stored information, to turn ON the group of lamps receiving electrical power from that power circuit.

11. A lighting control process for a space equipped with multiple lamps for illuminating the space and multiple power circuits for supplying power to different groups of said lamps, said process comprising:
-
storing information relating to the past illumination of the lamps in each of said different groups, detecting conditions or events that indicate that increased illumination of said space by said lamps is needed, producing a first control signal in response to the detection of a condition or event that indicates that increased illumination of said space by said lamps is needed, and in response to said first control signal, supplying power to at least one of said power circuits, which is selected on the basis of said stored information, to turn on the group of lamps receiving electrical power from that power circuit, said stored information comprises at least one type of information selected from the group consisting of the elapsed time that electrical power was supplied to one of said power circuits relative to one or more of the other power circuits, the number of times the supply of electrical power was initiated for one of said power circuits relative to one or more of the other power circuits, the elapsed time that electrical power was supplied to one of said power circuits per initiation of the supply of electrical power to that power circuit, relative to one or more of the other power circuits, and said power circuit selected to be supplied with electrical power in response to said first control signal is the power circuit having at least one of (1) the shortest cumulative time during which electrical power was supplied thereto, (2) the lowest number of times the supply of electrical power was initiated therefor, and (3) the lowest average time during which electrical power was supplied thereto per initiation of the supply of power thereto.

12. A lighting control system for an area equipped with multiple lamps, a plurality of electrical power circuits each of which is coupled to a different group of said lamps for turning the lamps in that group on and off, and one or more devices producing control signals in response to events that affect the amount of light desired from said lamps, said system comprising:
-
a controllable switch for controlling the supply of electrical power to each of said plurality of electrical power circuits, a memory storing information relating to the past illumination of the lamps in said different groups, and a controller coupled to said devices and said controllable switch for automatically selecting the electrical power circuits to which electrical power is supplied or interrupted based on said control signals and said stored information, said controller initially selecting less than all of said electrical power circuits to be turned on when all of said circuits have been turned off. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
