Abstract
A multicolor lamp system. The multicolor lamp system includes a dimming circuit and an illumination module electrically connected to the dimming circuit. The illumination module has a detection circuit for detecting the output of the dimming circuit. The detection circuit generates a detection signal corresponding to the output of the dimming circuit. A microcontroller is programmed to receive the detection signal and to supply a corresponding electrical signal to a plurality of LEDs. The LEDs are able to generate a variety of colors corresponding to the electrical signal supplied from the microcontroller. In a preferred embodiment the illumination module also includes an infrared receiver.
