| Patent Number: |

| Title: |
Color Wheel |
| Abstract: |
A light fixture having at least one light source for generating a beam of
light, a plurality of color filters are rotatable into position to
intercept the light beam. The color filters are fixed to the color wheel
by a central spring which has a number of radial protruding tongues for
fixation of the color filters. The color filters are removable yet are
secured in a correct position by radial protrusions formed between the
color filters an circular outer protrusion located outward of the color
filters so as to form a cavity that surrounds the color filter at both
sides as well as at outward. Inward of the color filters, they are fixed
by the protruding tongue that presses them down and keeps them in place.
This leads to a nearly perfect fixation of each color filter, which can
be exchanged if necessary.
