| Title: |
Color Filter Module for Projected Light |
| Abstract: |
A lighting module that projects various colors, hues, and intensities of
light. The device includes a light source and a reflector to direct the
light along an optic path. A primary optical element reduces the cross
section of effected light regions as the light enters a filter assembly
area in the optic path. Filters in the filter assembly are deployed in
varying combinations and to varying degrees to produce the color, hue, and
intensity of light desired by the user. The refracting action of the
optical element allows the filters to be physically positioned in the
optic path but to have no effect on the light until the filters are
rotated so that filter segments align with optical segments, and the
filter changes the light being projected from the lighting module.
