A method and system for controlling LED light field by multidimensional micro-perturbation and spatial integration

Abstract

This invention relates to the field of lighting control technology, and particularly to an LED light field control method and system that integrates multidimensional micro-perturbation and spatial fusion. The method includes: executing a multidimensional joint micro-perturbation sequence, comprising luminance micro-perturbation and color temperature micro-perturbation, on at least one luminaire in the lighting system, and measuring the total tristimulus values ​​of light under each perturbation state using at least one light sensor; constructing and solving an overdetermined system of equations based on the total tristimulus values ​​to separate the tristimulus values ​​of the light components of each luminaire and the tristimulus values ​​of the ambient light components; calculating compensation control commands for the luminaires based on the separated tristimulus values ​​of the ambient light components and preset target lighting parameters, and controlling the luminaires to execute the corresponding compensation control commands. This invention solves the technical problems of inaccurate light component estimation and insufficient control accuracy and robustness caused by limitations in separation methods in the prior art.
