Abstract:
1. A U-turn lens for a recessed light fixture including: a cylindrical lens bezel having a central longitudinal axis, an upper end extending along one end of the central longitudinal axis, a lower end extending along the opposite end of the central longitudinal axis, an inside diameter and an outside diameter; a tubular, transparent, cylindrical lens disposed within said bezel and oriented along the central longitudinal axis of said bezel, said lens having an internally-reflective outside diameter fitting substantially against the inside diameter of said bezel and comprising an input end corresponding with the upper end of the cylindrical lens bezel and an output end corresponding with the lower end of the cylindrical lens bezel, said cylindrical lens further comprising a substantially flat input surface at the input end and a substantially cylindrical opening in the center of the cylindrical lens extending inwards from the output end of said cylindrical lens said opening being defined by the at least one internally reflective surface and having an identical central longitudinal axis to the cylindrical bezel, said cylindrical lens further comprising an outward extending a flange extending from the cylindrical lens on the output end of the at least one internally reflective surface, said flange extending outwards and obliquely from said inner diameter towards said outside diameter, said lens extending beyond the lower end of the bezel, and receiving generally aimed light from the input end and emitting reflected light, said reflected light being emitted in a direction substantially perpendicular to the central longitudinal axis, said cylindrical lens further comprising an output face for transmitting said reflecting light in a direction substantially perpendicular to the central longitudinal axis.
