Light emitting panel assemblies include a light guide having a pattern of individual deformities of well defined surfaces and shapes that are projections or depressions on or in one or both sides of the light guide. The deformities are quite small in relation to the width and length of the light guide, and may vary or be random in size, shape or geometry, placement, index of refraction, density, angle, depth, height and/or type for controlling the light output distribution to suit a particular application.
