| Title: |
Color Changer Mechanism |
| Abstract: |
An improved color changer apparatus for use with lighting fixtures suitable
for performance lighting is disclosed. Each of a plurality of
parallel-spaced planar filters are adapted to be moved in and out of the
fixture beam by rotation in a plane perpendicular to the beam about an
effective pivot point. Each such filter is capable of continuous rotation
about its effective pivot point and the filters are so shaped that the
leading edge of one filter and the trailing edge of another can be aligned
such that no ray of light in the beam can pass through either both filters
or neither one.
