  • Patent number: 8662704
    Abstract: An optical system for lighting fixtures uses light emitting diodes arranged in a 2-D array. In one embodiment, a lighting system comprises a framework carrying a plurality of diodes, where each diode has an associated optic that projects the light with a “high,” “medium” or “low” vertical throw, as provided by prismatic “teeth” that refract and reflect light rays in a predetermined manner so that the combined illumination patterns of each diode can blend to generally uniformly illuminate a target surface without dark spots or regions. Each optic has a common primary portion and a selected secondary portion whose tooth/teeth have a “swept” geometry for better angular (vertical and/or horizontal) control of light rays. Structural variations between different secondary portions reside in various factors, including plurality of teeth, length of the tooth along the longitudinal axis A, curvature(s) in the vertical and/or horizontal directions, and angularity or tightness of curvature of the swept geometry.
