| Title: |
Variable Color Lighting Instrument |
| Abstract: |
A lighting instrument having pivotable dichroic filters arranged in a
substantially radial arrangement with respect to a projected light beam.
Multiple sets of such filters are spaced along the axis of the light beam
to vary the color of the light beam emitted from the instrument. A gearing
mechanism rotates all filters of each set in synchronization with each
other and independently with respect to filters of the other sets. The
filters may be positioned to pass unfiltered light to vary the saturation
of the light beam.
