Abstract
Light emitting panel assemblies include a light guide having a uniform or variable pattern of individual deformities of well defined shapes that are projections or depressions on or in one or more surface areas of the light guide. The deformities are quite small in relation to the width and length of the light guide. At least some of the deformities may have two or more surfaces that come together to form a ridge having a total length that is quite small in relation to the width and length of the light guide.
