  • Occupancy sensing smart lighting system
    Patent number: 9907138
    Abstract: A smart lighting system and method that estimates occupancy using perturbation-modulated light and distributed non-imaging color sensors. A system is disclosed that includes a plurality of non-imaging color sensors; a plurality of color controllable lights; a system that perturbs the color controllable lights within a space; a system that collects resulting color information from the non-imaging color sensors, and builds a light transport model based on collected color information; a system that estimates an occupancy pattern or distribution within a space; and an adjustment module that adjusts the color controllable lights based on the light transport model and a predefined control strategy.
    Type: Grant
