Abstract
An optical assembly includes a light emitting panel member having opposite sides and at least one input edge for receiving light from at least one light source, and a pattern of individual optical deformities on or in at least one of the sides for producing a light output distribution from a light emitting surface area of the panel member. Different sets of the optical deformities within the pattern each having at least one surface that is shaped or oriented to extract light propagating through the panel member in respective different directions from multiple regions of the light emitting surface area of the panel member.
