Abstract

An optical assembly comprises light sources and a light emitting panel member having an input edge to which each of the light sources is optically coupled at a different location along the input edge. Different sets of individual optical deformities on or in at least one of the sides of the panel member each have at least one surface that is shaped or oriented to extract light propagating in the same direction through the panel member in different directions for viewing from different angles through one of the sides of the panel member.
