LIGHT REDIRECTING FILMS AND FILM SYSTEMS

摘要

Optical assembly comprises a light emitting panel having at least one light source positioned adjacent to at least one light input edge located at or near a corner of the panel and at least one light output surface for emitting light. In close proximity to the light output surface is a light redirecting film for receiving light emitted from the light output surface. The film has optical grooves extending across the film in a curved pattern facing a corner of the film in close proximity to the corner of the panel to redistribute the light emitted from the light output surface.
