Claims
- 1. Apparatus for producing scrolling bands of colored light comprising:
(a) an assembly adapted to be rotated about an axis, said assembly comprising a plurality of transmissive color filters which extend along the axis and define an internal volume, a periphery, and two opposing ends; and (b) a reflecting surface located at least partially within the internal volume for receiving light which has passed through the periphery and reflecting said light out of one of said ends, said reflecting surface being adapted to remain stationary as the assembly rotates about the axis.
- 2. The apparatus of claim 1 wherein the transmissive color filters are dichroic filters.
- 3. The apparatus of claim 1 wherein the transmissive color filters substantially abut one another.
- 4. The apparatus of claim 1 wherein the transmissive color filters are separated from one another by opaque strips.
- 5. The apparatus of claim 1 wherein the periphery is substantially circular.
- 6. The apparatus of claim 1 wherein the periphery is segmented.
- 7. The apparatus of claim 6 wherein adjacent filters have mating angle-ground edges.
- 8. A scrolling method comprising:
(a) providing a plurality of color filters, each filter producing transmitted light from received light; (b) repetitively passing the filters in front of a light source by transporting the filters in a substantially circular path about a rotation axis, said light source having an optical axis which is substantially perpendicular to said rotation axis; and (c) turning the optical axis of the transmitted light produced by the filters so that said axis does not pass through a filter.
