Light emitting panel assemblies
First Claim
1. A light emitting assembly comprising at least one light source, an optical film with deformities and an optical conductor having front and back sides, and at least one light input surface for receiving light from the light source, the optical conductor having a pattern of deformities on or in the front and back sides to cause light to be emitted from at least one light emitting surface on at least one of the sides in a predetermined output ray angle distribution, at least one of the deformities varies, a transition area between the at least one light source and the light emitting surface, and at least one planar or curved refractive surface on the transition area aligned with the at least one light source to redirect a portion of the light entering the optical conductor in a predetermined manner to cause the light emitted from the light emitting surface to pass through the optical film, which redirects the light such that the light will pass through a liquid crystal display with low loss.

Abstract
Light emitting assemblies include at least one light source, an optical film with deformities, an optical conductor, and at least one light input surface for receiving light from the light source. The optical conductor has a pattern of deformities on or in the front and back sides to cause light to be emitted from at least one light emitting surface on one of the sides. At least one planar or curved refractive surface on a transition area between the light source and the light emitting surface or on the light input surface aligned with the light source redirects a portion of the light entering the optical conductor to pass through the optical film. A tray may also be provided that holds the optical conductor and light source.
