Abstract
An apparatus is disclosed comprising a lamp which produces a first light which may be a white light; a first light valve, a second light valve, a first color separator, and a first aperture device. The first color separator receives the white light from the lamp, and separates the white light into a first color light and a first residual light. The first aperture device receives the first color light and the first aperture device can be controlled to modify a frequency of the first color light to the first light valve. The second light valve receives at least a portion of the first residual light. The first aperture device could also be controlled to substantially block at least a portion of the first color light.

A stage lighting apparatus comprising:
- a lamp;
- a plurality of light valves;
- and wherein the lamp and the plurality of light valves cooperate to project an image comprised of a plurality of colors onto a stage;
- further comprising a control system;
- a communications node for receiving one or more unique address signals, one or more command signals and one or more program signals;
- wherein each of the one or more unique address signals is compared by the control system to a first unique address to allow response by the control system to command signals;
- wherein a first command signal of the one or more command signals received by the communications node varies the visual look of the plurality of colors;
- and wherein the one or more program signals received by the communications node contain information as to how the plurality of light valves are controlled to produce the image.
A stage lighting apparatus comprising:
- a lamp;
- and
- a lens;
- wherein the lamp and the lens cooperate to project an image comprised of a plurality of colors onto a stage;
- and further comprising a control system;
- and
- a variable lamp power supply;
- wherein the control system can automatically control the variable lamp power supply to vary power to the lamp based upon a saturation of the plurality of colors.
