Illumination system for non-imaging reflective collector

A first concave mirror (20) collects the light emitted by a light source (10) in a first half space (15) and forms a first image (21) of the light source at a point proximate thereto. A second larger concave mirror (30) opposite the first mirror (20) forms second and third images (32, 33) from the r...

Zusammenfassung:	A first concave mirror (20) collects the light emitted by a light source (10) in a first half space (15) and forms a first image (21) of the light source at a point proximate thereto. A second larger concave mirror (30) opposite the first mirror (20) forms second and third images (32, 33) from the respective source and first image. The second and third images are formed at the input aperture (42) of a non-imaging reflector (40), which in turn emits the light uniformly through the output aperture (44) thereof.
