An luminaire having a bipartite optical comprises an upper reflector including reflecting facets, and an opening in the reflector for emitting light from a light source to an area to be illuminated. A primary light source is mounted within the reflector, the primary light source having a diameter and a longitudinal axis which is substantially parallel to the upper reflector. An image of the light source is displayed by each of the facets in a predetermined direction, each the image being parallel and adjacent to edge for each of the facets. An illumination uniforming deflector is disposed below the primary light source to redirect light incident on it to the upper reflector for maximum utilization.
