ABSTRACT:
An improved lighting fixture is disclosed for imaging a high-intensity beam of light at a distant location. A specially-faceted near-elliptical reflector cooperates with a gate aperture and a single aspheric lens to produce a beam that incorporates a very high proportion of emitted visible light, while the reflector has a dichroic coating that reflects only a low proportion of infrared light. The projected beam thereby has a relatively low energy density, such that the front portion of the fixture can be reduced substantially in size and weight. The gate is selectively rotatable relative to the fixture's rear housing.
