| Patent Number: |

| Title: |
Variable Color Lighting System |
| 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.
