  • Patent number: 10462875
    Abstract: A method for controlling a chromaticity of total light provided by a lighting system includes detecting the total light by a sensor system, determining a component of the total light that is attributable to uncontrolled light, and selecting a calibration for a sensor based on the uncontrolled light, and using the calibration to adjust the output of the sensor system. The calibration tables may be based on spectral responsivity of the sensors in the sensor system and calibration functions rather than physical light sources. Relative intensities of controllable light sources having different xy values are then adjusted to cause the total light provided by the lighting system to approximate a target chromaticity. A daylighting system implementing this method includes controllable light sources with different xy values. The intensities of the controllable light sources are adjusted to augment sunlight to control the chromaticity of total light provided by the daylighting system.
