Abstract

A lens for distributing light from a light emitter in a desired asymmetric illumination profile includes a lens body having an input side and an output side. The input side receives light from an emitter, and the output side includes a major total internal reflection surface and a refractive surface. A primary emission axis associated with the emitter is defined through the lens body, and a transverse reference plane is positioned parallel to the primary emission axis. A desired illumination region is located on a first side of the reference plane, and a desired dark region is located on a second side of the reference plane. In some embodiments, the total internal reflection surface is entirely positioned on the second side of the reference plane. In additional embodiments, the total internal reflection surface includes a plurality of substantially planar adjacent longitudinal faces.
