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 light engine useful in the luminaire, and methods for making the light engine and the luminaire. The present disclosure further describes methods for crosswalk illumination using the bollard-style luminaires, and methods of communication between bollard luminaires. The bollard luminaire includes a design that generally confines light to illuminate the crosswalk 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.
