Embodiment Construction

[0063] A better understanding of the various features and advantages of the present invention will be obtained by referring to the following detailed description of the embodiments of the invention and the accompanying drawings, which illustrate exemplary embodiments that utilize the specific principles of the invention.

[0064] With reference to the attached drawings, the first figure 1 , one embodiment of the optic 100 includes a generally hemispherical shell integrator 102 with a light guide 103 extending from the zenith along a hemispherical curve down to the edge. At the zenith, the light guide 103 is provided with a reflective surface 301a (see image 3 ) to combine from a source at the center of the hemisphere (at figure 1 (not shown in ) is introduced into the light guide 103. The edges of the optic 100 may be provided with protruding lugs 104 or other formations to enable the optic 100 to be mounted as part of a light fixture. Such as figure 1 As shown, the light...

Abstract

A shell integrator has a hollow transparent body with inner and outer surfaces formed as arrays of lenslets. Each lenslet of the inner surface images a common source region in the middle of the hollow body onto a respective lenslet of the outer surface. Each lenslet of the outer surface forms a virtual image of the respective lenslet of the inner surface at the common source region. One integrator has a light-guide following the surface of the hollow body from an inlet end at a central region of the surface to an outlet end at a rim of the hollow body. The light-guide inlet end is shaped to receive light from the common source region and direct such light along the light-guide. Another integrator is generally elongated, and may be semicylindrical. Any of these integrators may have a stepped surface forming a Fresnel lens.
