Light emitting panel assembly includes an optically conductive panel member having at least one input surface and a greater cross-sectional width than thickness, and at least one light transition emitter having a light emitting surface in close proximity to the light input surface. The light emitting surface has an output distribution defined by a greater width component than height component, a thickness equal to or less than the thickness of the panel member and a greater width than thickness in the width direction of the panel member. A reflector extends around the light source and is shaped to reflect and focus the light emitted from the light source at an acceptable angle for entering the light source.
