Abstract:
A lamp comprising:an optical module including (i) a plurality of LEDs including LEDs for emitting light of first, second, and third different colors, and (ii) a heat sink thermally coupled to the LEDs, the heat sink having an electrical conduit for transmitting conditioned electrical power to the LEDs; and an electronics module receiving input electrical power and a lighting control signal, the electronics module including an output couple rigidly attaching to the optical module for delivering conditioned electrical power to the electrical conduit, the electronics module further including electrical conditioning circuitry for selectively electrically coupling the input electrical power to the output coupler based on the lighting control signal to selectively power to the LEDs of the first second and third colors to produce light of a color selected by the lighting control signal.
