Abstract
This invention is a light fixture concept using geometrical optical elements and optical diffusors which produce a controlled light beam from a large lighting aperture. The object of this invention is to provide for both low surface luminance of the light fixture aperture and directional control of the light distribution. The geometrical optical elements are placed so as to result in a magnification of the light source, and diffusor elements are used to shape the light beam. A wide range of light sources can be used with this concept. The resulting light fixture will have reduced glare characteristics due both to the decreased luminance of the fixture aperture and to the restricted lighting angle distribution. These light fixtures should find application in a large number of lighting situations.
