Variable color lighting system
DCFirst Claim
1. A variable color lighting system comprising lamp means for providing variable color lighting effects in response to input control signals, each such lamp means including a plurality of light source means, each adapted to provide light of a different color, intensity control circuit means for each said light source means operative to control and vary the intensity of a light source means in response to said input control signals and address circuit means operative to permit operation of said intensity control circuit means upon receipt by said address circuit means of a predetermined address signal, and remote central controller means operative to provide said input control and predetermined address signals to said lamp means.

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.
