  • Patent number: 5678334
    Abstract: A display board, such as an advertising sign, information sign, road sign, or the like, comprises a panel 10 of transparent material which has at least one lighting element 13 for illuminating the panel from the edge on at least one lateral defining edge. At least one of the two flat sides of the panel is at least partially covered with an opacifier film. The panel which is provided with the opacifier film is provided to backlight display symbols to be mounted onto he front flat side seen by an observer. The light reaching the contact face between the panel and opacifier film, form the panel into the opacifier film, is scattered by the opacification of the film, so that the entire opacifier film lights up and provides an evenly bright face for backlighting a panel provided with display symbols.

  • Patent number: 5136483
    Abstract: An illuminating or light emitting device for use as a headlamp, a signaling lamp or other lamp for shining light in a beam or otherwise. It comprises as its main parts a generally flat transparent illuminating element with a circumferential edge in which a plurality of light emitting elements such as LED's are set. The edges are provided with an inwardly reflecting layer. The front side of the illuminating element is in the form of a light radiating surface, while the rear side is completely covered with an inwardly reflecting layer. Such an illuminating device may have a very flat overall shape, has a low current requirement and has a large homogeneous radiating area. It more especially lends itself to use on vehicles.

  • Patent number: 5027258
    Abstract: An illuminated display unit such as a board with a house number thereon or an advertising billboard, has a light guide panel. At least one electrical illuminating element is arranged in the vicinity of at least one lateral limiting edge thereof. The light guide panel serves for illuminating logo symbols, which are preferably in the form of film or of vapor coated layers, on the light guide panel. At least one of the lateral limiting edges of the light guide panel is provided with a light guide batten whose thickness is in excess of the thickness of the light guide panel and at least one of the illuminating elements is mounted in the batten. The transition between the light guide batten and the light guide panel is designed so as to have a high optical conductivity or transmittivity. The external surfaces of the light guide batten are provided at least partly with an inwardly reflecting layer.

  • Patent number: 4903172
    Abstract: An illuminated display unit such as a house number, traffic sign, advertisement carrier and the like comprises a fluorescing or photoconductive plate adjacent an edge of which is fitted at least one light-emitting element, in particular a light-emitting diode. The edge is provided with a reflecting layer to prevent emergence of light. Display symbols or their negatives are arranged, as viewed by the onlooker, on the rear face of the photoconductive plate. As a result of the total reflection for a photoconductive plate on the front and back and on the reflecting layer at the edges, the light produced by the light-emitting diode can issue only at the contact surface with the display symbols, so that the light is concentrated very strongly there and a great display brightness is produced. This is even more effective when a contrast surface is arranged behind the plate.
