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.
Claims7
A lenticular lens for distribution of light comprising a plurality of contiguous polygonally-perimetered lens elements, each said lens element having a light entrance surface and a light exit surface, said light entrance surface comprising an aspherical surface defined by a plurality of coaxial zones of different predetermined radii, said light exit surface being substantially planar.
A luminaire for high intensity light comprising a casing, a parabolic reflector positioned within said casing, means for supporting a high intensity lamp at the focal point of said reflector, and a lenticular lens positioned as the face plate of said luminaire, said lenticular lens comprising a plurality of contiguous polygonally-perimetered lens elements, each lens element having a light entrance surface and a light exit surface, said light entrance surface being substantially aspheric and being defined by a plurality of coaxial arcuate zones of differing radii, said light transmitting surface being substantially planar.
