ABSTRACT:
An edge light for projecting light into a lighting panel through an end surface of the lighting panel. The edge light includes a thin transparent optical guide member having an elongate portion and at least one end portion extending from the elongate portion. The elongate portion has a planar surface and a shaped surface generally parallel to the planar surface and configured for reflecting light within the guide member through one of the planar surface and the shaped surface. Either the planar surface or the shaped surface is positioned adjacent the end surface of the lighting panel when the edge light is used to illuminate the panel. The edge light also includes a light source positioned at the end portion for projecting light into the elongate portion of the optical guide member.
