Abstract
A lighting system is provided with a device for emitting light in response to receiving electrical current, a microprocessor and a current source. The microprocessor is programmed to provide a color control signal and an intensity control signal that are independently controllable relative to each other. The current source is adapted to provide the electrical current to the device at an amplitude based on the color control signal and at an on-off timing based on the intensity control signal.
