Patent ID: 8664864

Claim:
An apparatus, comprising: a controller module operatively coupled to two or more light sources, at least a first one of the light sources being configured to emit light having a first color and a second one of the light sources being configured to emit light having a second color, wherein the first and second colors are different than each other, the controller module configured to generate two or more switching sequences, each switching sequence for controlling operation of one of the light sources, the two or more switching sequences configured to result in generation of a desired lighting effect and two or more different measurable combinations of light, at least one measurable combination comprising light from one or more of the light sources; a broadband optical sensor configured to receive each different measurable combination of light, to detect each different measurable combination of light, and in response to each different measurable combination of light to output an optical sensor output signal indicating a total intensity of the measurable combination of light; a light measurement module operatively coupled to the controller module and configured to receive signals indicative of the switching sequences, the light measurement module configured to define one or more measurement sequences based on the switching sequences, the light measurement module further being operatively connected to the broadband optical sensor to receive the optical sensor output signal and further being configured to produce one or more light measurements in response to the optical sensor output signal and the based on the measurement sequences; and a processing module operatively coupled to the light measurement module and the controller module, the processing module configured to determine an indication of the light output by at least one of the two or more light sources based at least in part on the one or more light measurements and the two or more switching sequences.
