Abstract
Abstract A spotlight includes a housing with an illumination source moveably mounted therein and a lens assembly moveably mounted therein. One or more lenses are mounted in the lens assembly, each in one of a plurality of predetermined positions. Independent movement of the source and lenses conveniently provides a variety of field angles, light outputs, or other illumination characteristics. A reflector, framing shutters, iris, pattern grids, and color filter gels may also be used as desired.
