Patent ID: 7186003

Claim:
A lighting system, comprising: two or more LEDs configured to produce at least two different spectra of radiation; a processor including a memory; a controller configured to control power delivered to at least one of the two or more LEDs, the controller being responsive to at least one signal communicated to the controller from the processor; a light-transmissive material, wherein the two or more LEDs are arranged such that at least some of the radiation passes through the light-transmissive material and exits as variable color radiation; and a user interface coupled to the processor, wherein: the user interface supplies a user interface signal to the processor, the user interface signal including at least one of a logic high signal and a logic low signal; and the processor selects a program from the memory upon receipt of the user interface signal, wherein the program, when executed by the processor, controls at least a color of the variable color radiation.
