ABSTRACT:
A luminaire includes a light pipe having an optical axis. The light pipe includes a tube with a structured outer surface and a smooth inner surface. A reflective light extractor is positioned in the tube such that light reflected by the extractor will strike the tube on a first side. The first side has a contour such that the direction of travel of light reflected by the extractor will have a projection in the plane perpendicular to the optical axis that makes a predetermined angle with the smooth surface.
