Abstract: A light duct elbow having two light conduits capable of transporting light along two different propagation directions. A light diverter is located between the light conduits and has a reflector for directing light along the light conduits. In the light duct elbow, a light ray propagating within a collimation angle in the first light conduit that intersects the reflector is diverted to a second light ray propagating within the collimation angle in the second light conduit.

Abstract: The present disclosure describes light delivery and distribution components of a light duct that can be used as a luminaire, such as a bollard-style luminaire that can be useful for the illumination of pedestrian crosswalks. The bollard luminaire includes a design that generally confines light to illuminate the cross-walk and the pedestrian in the crosswalk, such that light that could produce glare for the pedestrian and/or a driver approaching the crosswalk is minimized The delivery and distribution system (i.e., light duct and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct.
