Abstract
Light emitting panel assemblies include a light guide having a pattern of individual deformities of well defined shape that are projections or depressions on or in at least one side of the light guide. At least some of the deformities are quite small in relation to the width and length of the light guide and have two or more surfaces that come together to form ridges. At least some of the ridges are nonlinear over a majority of their length and have opposite end points that intersect the light guide or other deformities where the ridges end.
