STRUCTURAL LIGHTING ELEMENT

摘要

The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes at least one curved portion and a remote light source. 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. The light delivery and distribution system can further function as a structural element that adjoins at least two walls of an illuminated enclosure or supports the shelves of illuminated shelving, joining the unit together.

主权项

1. A structural lighting element, comprising:
a hollow light duct having a longitudinal axis, opposing first and second ends, and a light output region; a reflective interior surface of the hollow light duct including a light transmissive region adjacent the light output region; a first light source positioned proximate the first end and capable of injecting a first light into the hollow light duct; and at least one tab extending from an exterior surface of the hollow light duct, capable of adjoining the hollow light duct to a support,wherein light rays propagating through the hollow light duct that intersect the light transmissive region, exit the hollow light duct.
