Abstract
Abstract A luminaire includes a lenticular lens. Each lentical comprises a convex lens having a highly polished aspheric curved surface. The aspheric surface is divided into a plurality of coaxial zones, each designed to accept a specific quantity of parallel light flux from a parabolic reflector positioned within the luminaire and then refract that quantity of flux into a specific solid angle of the projected beam. The convergence of light rays by each lens element produces a real image of the light source in front of the lenticular lens. Each lentical produces a separate image and all images were substantially identical.
