Abstract: A lens holder includes which a bottom cover, a top cover, sliding means and clipping means for holding lens assemblies in an optical lighting system. The bottom and top covers have a plurality of slot extensions lining the interior of the two covers. The top cover clips to the bottom cover by a set of clips on each side of the top cover to a set of clip slots on each side of the bottom cover. Lens assemblies can consist of lenses assembled in a holder along with individual lenses which can slide into between slot extensions.

Abstract: A diffusing dimmer includes an arm formed of non-transparent material and having a first end and a second end. The first end includes a mounting attachment. An extension portion of light diffusing material is connected to the second end and extends outwardly from the second end to a terminal edge formed in the light diffusing material. A pair of diffusing dimmer arms may be mounted in a light fixture movable toward each other in overlapping relationship to gradually diffuse and eventually block a light beam which projects lighting effects from the fixture. Also, rapid movement of the arms provides a strobing effect.

Abstract: An automated color mixing wash luminaire includes a movable yoke and a housing movably connected to the yoke. The housing has a first portion including a light source and provides for removing heat generated from the light source. A second portion of the housing includes movable color filters and a power lens. The light source is operable to project a beam of light along a path through the color filters and the lens. Heat removal is provided by cooling fins and at least one heat filter supported in the path of the beam so that a portion of the beam passes through the heat filter and a portion of the beam is reflected from the path toward the cooling fins. The power lens is formed by a disc of cast transparent material including several lens elements in a honeycomb pattern. Each lens element has a convex surface. At least one of the color filters is a gradient density color filter formed of a disc-shaped substrate having a planar surface including a photolithograpically etched film deposited thereon.
