OPTICAL SYSTEM FOR UNIFORM ILLUMINATION OF A TARGET AREA

Abstract

An optical system is adapted to direct light rays toward a target area. The system includes a reflector with an optical chamber having an upper aperture, a lower aperture, a chamber axis, and an internal reflective surface. The upper aperture receives light from a light source. The internal reflective surface directs the light rays toward the lower aperture. A lens extending within a lens plane is oriented at a first angle relative to the chamber axis. The lens includes an entrance face and an exit face opposite the light entrance face. The lens includes a first set of prisms on the entrance face, configured to bend the light relative to the optical axis and toward a target area, and a second set of prisms oriented at an angle relative to the first set of prisms and configured to disperse the light laterally, relative to the target area.
