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.
