Fiber Optic, I.e., Light Pipe Patents (Class 40/547)
  • Patent number: 4139261
    Abstract: A display comprises a plurality of addressable display panels each having a display zone for displaying visual information and arranged in a formation so as to collectively provide a composite display of increased area. A fibre optic image transform construction is arranged in front of the display panels for transforming an image collectively provided by the panels into a corresponding continuous image in which discontinuity between adjacent panel display zones is eliminated.

  • Patent number: 4115942
    Abstract: A message display arrangement having particular adaptability for use on a wheeled vehicle, such as a bicycle, characterized by a display unit for presenting a succession of indicia information in response to the movement of the vehicle. Structure on a spoke of the vehicle wheel selectively rotates an indicia carrying segment wheel in front of a source of light, where the indicia pattern is transmitted to the display unit through a system of fiber optic strands.

  • Patent number: 4113347
    Abstract: An arrangement for directional radiation of light in symbol-indicator systems which are to be effective over fairly large distances, with the symbols being formed by dots of a dot matrix which receive light from respective light conductor bundles, particularly for utilization as additional indicators in the railroad signalling field, in which each matrix dot is provided with a lens arrangement comprising two horizontally adjacent lenses having their plane surfaces facing the illuminating light conductors with the two lenses being cooperatively disposed to reproduce two horizontally adjacent partially superimposed light sources in the plane of observation.

  • Patent number: 4106231
    Abstract: The following specification discloses a low level lighting indicator readout or display of the type having a lighting source such as incandescent lamps that have been placed in a heat sink. The incandescent bulbs or lamps are connected to a logic network, so that one or a plurality of bulbs can be lit by the logic network in order to cause a particular display to be registered. The display is registered by means of the lamps passing light through a series of conductive light tubes such as fiber optic members that emanate therefrom to form a series of optical readouts in the form of dots, or segments, such as bar displays. The termination of the light pipes provide a matrix in the form of a dot pattern that can be driven to create various displays in the form of alpha numeric representations or other symbols.

  • Patent number: 4068118
    Abstract: An illuminated optical fiber display system for Christmas trees, ornamental displays and signs and the like, in which an elongated column having a hollow interior contains a fluorescent light tube and the column supports a plurality of optical fiber elements enclosed in a sheath extending outwardly from the column and having the inner ends in a position to receive light from the fluorescent light tube in the column. The optical fiber elements may be decorated to resemble evergreen branches. The fluorescent light or a sleeve around the fluorescent light, containing colored and shaded areas, is rotated to vary the lighting characteristics emitted from the outer ends of the optical fiber elements. The concept involved in the present application has sufficient versatility that the sleeve and/or fluorescent light and the shading and coloring thereon may be varied to provide the ornamental characteristics desired.
