Abstract:
1. A solid-state lighting module, comprising: solid-state light emitters that emit light of different colors and are selected from separated groups of solid-state light emitters that emit light of two or more separated colors, wherein one or more solid-state light emitters are selected from each of the separated color groups of solid-state light emitters; a programmable device that stores or remembers desirable optical intensities of the separated color groups of solid-state light emitters; a control circuit that individually controls light intensity of each of the separated color groups of solid-state light emitters, the light control circuit being coupled to or in communication with the programmable device to receive the desirable optical intensities of the separated groups of solid-state light emitters and operable to adjust the intensities of the separated color groups of solid-state light emitters based on the desirable intensities; and a light detection system that includes a single photodetector to measure light emission from the separated groups of solid-state light emitters; wherein during an off time of the solid-state light emitters, the control circuit is configured to control the solid-state light emitters of the separated color groups to turn on each of the separated color groups one at a time during different non-overlapping designated time durations to obtain measurements of light emission of different separated color groups at different respective designated time durations.
