Abstract
A luminaire module including a plurality of light-emitting elements (LEEs) arranged to emit light in a forward direction; a light guide comprising a pair of opposing side surfaces extending from a receiving end of the light guide to an opposing end of the light guide, the light guide configured to guide light received at the receiving end from the LEEs in the forward direction to the opposing end, wherein the light guide is elongated along a transverse direction orthogonal to the forward direction; and an optical extractor elongated along the transverse direction and located at the opposing end of the light guide to receive the guided light, the optical extractor comprising a redirecting surface and an output surface, wherein the received light undergoes two reflections off the redirecting surface prior to being output through the output surface in an ambient environment as output light in a backward angular range.
