    摘要： Apparatus for providing backlighting of a display comprising the use of louvered material between a light source and the sides of a prism wherein the prism is utilized to transmit and direct light rays to the display surface. The use of the prism in some embodiments eliminates direct viewing of the light source through the louvered material.

    摘要： IN AN ILLUMINATED DISPLAY, USEFUL FOR ADVERTISING AND AS A WORK OF ART, THE FACE OF THE DISPLAY IS SUSPENDED ABOVE A REMOTE SOURCE OF SUBSTANTIALLY PARALLEL LIGHT RAYS AND COMPRISES AT LEAST ONE LIGHT TRANSMITTING PORTION EXCTERIOR TO A BODY ARRANGED TO RECEIVED THE PARALLEL RAYS, INCLUDING A DEFLECTOR ADAPTED TO DIRECT THE PARALLEL RAYS SO THAT THEY IMPINGE UPON THE INTERIOR OF THE LIGHT TRANSMITTING PORTION, THE ILLUMINATED FACE POSSESSING THE ESTHETIC EFFECT, TO AN OBSERVER, OF BEING SUSPENDED IN AIR ON RAYS OF LIGHT. THE DEFLECTOR CAN BE ADJUSTABLE (E.G. TUNABLE) AND CAN COMPRISE TWO HINGED REFLECTIVE FACES WHICH ARE CAPABLE OF ADJUSTMENT BY RAISING OR LOWERING A HINGE LINKAGE CONNECTING THE TWO FACES. THE DEFLECTOR CAN HAVE A CORRUGATED SURFACE COMPRISING BOTH PRIMARY AND SECONDARY REFLECTIVE SURFACES, THE PRIMARY REFLECTIVE SURFACES BEING POSITIONED SO AS TO DIRECTLY RECEIVE THE PARALLEL LIGHT RAYS AND DIRECT THEM TOWARD THE FACE AND, THE SECONDARY SURFACE BEING POSITIONED SO AS TO RECEIVE LIGHT REFLECTED FROM THE INTERIOR OF THE FACE AND REDIRECT IT BACK ON TO THE INTERIOR SURFACE OF THE LIGHT-TRANSMITTING PORTION OF THE FACE.
