Abstract
An illumination system for providing higher efficiency and greater control over uniformity of illumination of non-circular apertures, which are commonly rectangular. The illumination system comprises a reflector of substantially ellipsoidal form surrounding a light source, and which has a concave reflection surface formed of a plurality of curved reflective segments extending along the length of the reflection surface, each of which is tilted and rotated by a predetermined amount to direct light from the reflector almost entirely into the area encompassed by the rectangular aperture including portions of the area which lie outside of a circular area inscribed within the aperture.
