Abstract
Optically patterned waveguides and systems employing optically patterned waveguides are provided. The optically patterned waveguide is configured for use in a lighting system and arranged perpendicular to an overhead structure, such as a ceiling. The optically patterned waveguide includes major surfaces that are patterned with a plurality of elongated facets formed into the major surfaces and extending in a direction parallel to the length of the waveguide. The optically patterned waveguide provides illumination patterns having increased uniformity.
