Abstract
A light emitting assembly comprises a light source and a light emitting panel member having a panel surface and an input edge for receiving light from the light source. On or in the panel surface is a pattern of individual light extracting deformities. Each of the deformities has a well defined shape and a length and width substantially smaller than the length and width of the panel surface. At least some of the deformities have only two surfaces, each having opposite peripheral edge portions that intersect each other and intersect the panel surface. One of the surfaces of the deformities is substantially perpendicular to the panel surface and is curved in a transverse direction. The other surface of the deformities is a sloping surface.
