Abstract
A lighting assembly includes a light guide having a first major surface, a second major surface opposite the first major surface, a light input edge, and an end edge distal the light input edge. Light input to the light guide through the light input edge propagates by total internal reflection toward the end edge. The lighting assembly further includes light extracting elements at least one of the major surfaces of the light guide, the light extracting elements configured to extract light through the first major surface in a direction away from the light input edge and away from the first major surface, and a banding reduction element at the end edge configured to redirect light incident thereon in a direction away from the light input edge.
