Modular Light Guide Luminaires

摘要

The present technology relates to achieving a low manufactured cost and high design alignment robustness for fabrication of modular light guide luminaires featuring solid state light-emitting elements.

主权项

1. A luminaire module comprising:
one or more light-emitting elements (LEEs) disposed on one or more substrates and adapted to emit light in a forward direction; a light guide comprising an input end and an output end, and side surfaces extending from the input end to the output end, the side surfaces shaped to guide light emitted by the one or more LEEs and received at the input end of the light guide in the forward direction to the output end of the light guide and provide guided light at the output end of the light guide; and an optical extractor optically coupled with the output end of the light guide and adapted to receive the guided light, the optical extractor having a first redirecting surface and one or more output surfaces, the first redirecting surface of the optical extractor being adapted to reflect at least a portion of the light received at the optical extractor in a first direction that has a component orthogonal to the forward direction, wherein at least one of the first redirecting surface or at least one of the one or more output surfaces diffuse light.
