Method and apparatus for implementing a pulse skip method of controlling light intensity

Abstract

A method and an apparatus for modulating light emitted by an at least one LEDs using a pulse skip modulation technique (PSM). The apparatus having an at least one first LED adapted to output at least first radiation having a first spectrum, an at least one second LED adapted to output second radiation having a second spectrum different than the first spectrum, and at least one controller coupled to the at least one first LED and the at least one second LED and configured to communicate with an at least one controller, the at least one controller further configured to independently control at least a first intensity of the first radiation and a second intensity of the second radiation, wherein the at least one controller is configured to implement a pulse skip modulation (PSM) technique to control at least the first intensity of the first radiation and the second intensity of the second radiation.
