Abstract: A lighting system can comprise an edgelit panel, for example a lightguide that may have a panel or slab shape with an edge that is illuminated by an array of light emitting diodes extending along the edge. The edgelit panel may have light directing features associated with the edge. The light directing features can redirect light that is coupled through the edge. The redirected light can emit from a major face of the lightguide to produce a correspondingly redirected pattern of illumination. The resulting illumination of the lighting system can be biased in a particular direction as may be useful for various lighting applications. For example, in a streetlight application, the lighting system can produce illumination that is biased in a street side direction relative to a house side direction.
