International ClassG02B 026/02AbstractA method for optimizing the energy efficiency of a lighting system including a plurality of light sources, which includes the steps of defining a set of parameters for the lighting system, and using a linear programming technique, taking into account the set of parameters, to produce energy allocation output data which satisfies a total energy consumption constraint that the total energy allocated to the lighting system not exceed a target energy consumption level, and which is representative of an optimal allocation of energy to each of said light sources. The lighting system is installed in a building which includes a plurality of rooms each of which is equipped with at least one of the light sources. In general, the lighting optimization problem is translated into a linear programming problem by formulating a set of lighting system energy allocation constraints, converting these constraints into a set of constraint equations and a cost function, converting the constraint equations into a set of simultaneous linear equations, and then solving the set of simultaneous linear equations in such a manner as to minimize the cost function, to thereby produce the energy allocation output data, which is preferably in the form of an optimal brightness level for each light source. These steps are preferably implemented in computer software, which is preferably loaded in a programmable central controller of an intelligent lighting control system which is responsive to the energy allocation output data for automatically adjusting the brightness level of each of the light sources to the optimal brightness level therefor. Preferably, available energy remaining after satisfying minimum brightness levels for each room is allocated at least partially on the basis of the designated priority level of each room, and/or the energy efficiency of the light sources.Other References
