ETENDUE-SQUEEZING ILLUMINATION OPTICS

摘要

In some embodiments, an apparatus for use generating illumination is provided that comprises a reflective base (33), a first light source (31) positioned proximate the reflective base, and a reimaging reflector (30) positioned partially about the first light source, where a percentage of light (36) emitted from the first light source is reflected from the reimaging reflector to the reflective base adjacent the first light source establishing a first real image (37R). T.he reimaging reflector can further comprise a first sector (30R) of a first ellipsoid and a second sector (30L) of a second ellipsoid, where the first and second sectors establish the first and a second real. images (37R, 37L). Further embodiments provide a lens (60) that includes a reimaging reflector (62) that receives light and reflects the light establishing a first real image. The reimaging reflector can further comprise a plurality of sectors that: reflect light to establish first and second real images.
