Patent ID: 7800315

Claim:
A method of varying an intensity of light emitted from at least one or more substantially similar light emitting diodes, a first electrical biasing for the at least one or more substantially similar light emitting diodes producing a first wavelength shift, a second electrical biasing for the at least one or more substantially similar light emitting diodes producing a second wavelength shift which is opposed to the first wavelength shift, the method comprising: monitoring an input control signal, the input control signal designating a selected intensity level; retrieving a plurality of parameters stored in a memory, the plurality of parameters designating a corresponding combination of the first electrical biasing and the second electrical biasing for the selected intensity level; processing the plurality of parameters into at least one input electrical biasing control signal; and operating the at least one or more substantially similar light emitting diodes with a time-averaged modulation of forward current conforming to the at least one input electrical biasing control signal to provide the selected intensity level within a dimming cycle.
