Abstract: A variable beamwidth stage light relying upon an axially movable reflector for changes in beamwidth. The reflector has a plurality of radially outwardly and axially forwardly extending leaves in side-by-side relation to define a bowl-shaped reflector surface. A stationary support flange is in frictional contact with the radially outward surface of each leaf. The reflector leaves are sandwiched between a base member and a ring member at the base of the reflector. A motor driven lead screw is attached to the base member to cause axial movement of the reflector relative to the support flange. The reflector defines a first and a second focal point along the axis of the reflector. A light source is fixed at the first focal point, which remains substantially fixed relative to the base member.

This ball-and-socket mounting, which is coaxial with respect to the adjusting screw can be assembled by robots and does not cause any bending moments that unfavorably affect the reflector mounting.

Abstract: In a spot projector having a reflector, a coiled filament lamp, a gate and a lens, improved light output efficiency is provided by locating the virtual filament center intermediate the reflector and the natural focus of the reflector. The gate is provided with an aperture which is substantially equal to or larger than the aperture of the reflector to accomodate the divergence of light rays produced by locating the filament to the rear of the focus point. Because the distribution of the light rays which emanate from the filament approximates a cosine distribution, and because the location of the virtual filament is behind the actual focus point, the percentage of light rays which are projected transversely through a region between the reflector and the gate is substantially reduced, and a correspondingly greater amount of filament illumination is reflected through the gate aperture, thereby producing a brighter image than would be produced by the same lamp located forward of the focus.
