Abstract
The variable color lighting system includes a plurality of lamps controlled by a central controller. The central controller has a number of control channels, and each lamp is preset to be responsive to a specific control channel. To accomplish this, a lamp includes an address circuit which can be varied to respond to a unique address signal from any of the control channels. When the proper address is received, intensity control circuitry within the lamp responds to a digital intensity control signal transmitted by the central controller. The central controller causes all light sources in a lamp to fade from one end intensity value to the next and to reach the next intensity value simultaneously.
