Patent ID: 7333011

Claim:
A lighting system, comprising: a plurality of luminaires; an input device through which a predetermined light setting is selected for each of the luminaires; a databus communicatively linking the input device to each of the luminaires, such that the predetermined light settings are digitally transmitted via the databus to the respective luminaires, wherein each luminaire comprises: an emitter module including a light-emitting diode (LED)-based light source, the emitter module including at least one color channel; an optical sensor configured to periodically produce a measured output by measuring an intensity output of the emitter module; and a regulating device configured to regulate current delivered to each color channel in the emitter module based on a comparison of the periodic measured outputs of the emitter module to the respective predetermined light setting, wherein the emitter module includes a plurality of color channels, each color channel including at least one LED, and the optical sensor is configured to produce the measured output by measuring an individual intensity output for each of a plurality of colors corresponding to the color channels.
