Definitions

  • a light indicator device of the type described above is already known (DE-PS 34 12 229).
  • holes are provided in the transparent display panel, which holes start from the rear of the display panel and are not continuous.
  • the optical fiber bundles with their cylindrical sockets are inserted into these holes.
  • a conical or approximately conical air gap is provided between the flat ends of the optical fiber bundles and the display panel.
  • the small display elements, the ends of the optical fiber bundles do not require any modification or distortion of the objects shown.
  • the ends of the optical fiber bundles can be easily installed and replaced if necessary.
  • the panel or table therefore has a smooth front surface that does not offer dust deposits and is also easy and quick to clean.
  • the scoreboard is made of plexiglass in particular.
  • the ends of the optical fiber bundles facing away from the display panel are illuminated by light sources which e.g. controlled by a data processing system so that they indicate the operating states of the light sources in the system.
  • a luminous display device for optically displaying a large amount of information on a display panel, in which a plurality of optical fiber bundles are illuminated by a common light source.
  • a liquid crystal layer is arranged between the light source and the respective light guide bundle, the light scattering or light transmittance of which can be changed via an electric field.
  • the operating states of devices arranged in a spatially distributed system are also shown on the display panel, on each of which a plan of the system is shown to scale or schematically.
  • the ends of the optical fiber bundles are arranged at those points at which an operating state is to be represented (DE-OS 35 23 435).
  • the invention is based on the object of further developing a light display device of the type described at the outset in such a way that it can be adapted more easily and quickly to changes in the plan and changes in position of the locations to be illuminated in the plan.
  • the display panel is divided into segments which can be mounted separately from one another, that recesses are provided at the locations to be illuminated on the back of the segments, that the backs of the segments are each covered by a light-diffusing film and that the versions of the Optical fiber bundles are arranged in recesses of plates adjacent to the foils of the segments, which are each adapted to the outline of the adjacent segment and with their cutouts at the points of the segments to be illuminated reach as far as the foils.
  • a depression of the desired shape is made on the back of the segment at the corresponding point.
  • a recess for the end of an optical fiber bundle is provided in the plate adjoining the segment; through which the spot is illuminated.
  • the indentation in the respective segment, in conjunction with the film, causes a certain amount of light to be scattered, so that the illuminated areas can also be clearly seen from the side.
  • Recesses in the plate that are no longer required due to changes in the locations to be illuminated can remain in the plate. Since the optical fiber bundles are removed from these locations, the display panel at these locations is no longer illuminated despite the cutouts.
  • the depressions in the segment or the cutouts in the plate can be made by drilling, milling and the like.
  • the respective segment is connected to the film and the plate by a flexible strip of material attached to the narrow sides.
  • the segment and the film are thereby captively attached to the plate.
  • the segment with the film can be folded away from the plate if processing of the segment or plate is necessary. This type of attachment also ensures that the corresponding recesses in the plate and recesses in the segment have the correct position to each other after stacking.
  • the flexible strip of material preferably consists of a fabric. It can be a plastic fabric.
  • the plates are made in particular from pressboard. Recesses in such panels can be made quickly and easily by using wood drills or wood cutters can be used.
  • the flat ends of the optical fiber bundles are arranged at a distance from the film and the walls of the cutouts between the ends of the optical fiber bundles and the film are each white or reflective. As a result, uniform illumination is achieved at the point of the film covering the recess.
  • the segment has e.g. a thickness of 5 mm.
  • the depressions in the segment are in particular about 0.5 to 1 mm high.
  • the plate also has a light display device composed of numerous segments and has a thickness of approximately 20 mm.
  • the display panel 2 of the light indicator device 1 is composed of individual segments 3, 4, 5, which consist of flat, transparent plates, which are in particular rectangular and have the same dimensions.
  • the segments 3 to 6 consist of plexiglass, for example.
  • the segments 3 to 6 form with other segments, not shown, a tableau, on which, schematically or to scale, a plan is attached to the aerodrome part containing the aerodrome lighting system.
  • the invention is not limited to airfield lighting systems but can also be used in other technical processes, for example traffic lights locations, railway systems, manufacturing processes, monitoring systems to display operating states.
  • the headlights are controlled, for example, via a data processing system, the switches for the energy supply to the headlights are actuated and checks whether the headlights work in accordance with the respective switch-on and switch-off commands.
  • Each segment contains part of the airport map. At those points in the plan which headlights in the airport correspond to, for example, for runway lighting, there are 3 to 6 recesses 7, 8, 9 on the back of the segments, which are produced, for example, by drilling or milling.
  • the depressions preferably have the shape of a symbol which is assigned to the respective lighting. Common headlights are circular, for example.
  • Orders 10 for example in color, are provided on the back of the segments 3 to 6 with which the plan is shown.
  • the recesses 7, 8, 9 are provided, which are usually not provided with colored markings.
  • At least the depressions 7, 8, 9 are covered by a film 11 which has a light-scattering effect.
  • the film 11 is generally of the same size as the rear of the respective segment 3 to 6.
  • the films 11 are adjoined by plates 12, 13, 14, 15 in each of the segments, the outlines of which correspond to the outlines of the segments 3 to 6.
  • the segments 3 to 6, foils 11 and plates 12 to 15 are square or rectangular.
  • the plates 12 to 15 are each stronger than the segments 3 to 6. Segment thicknesses of 5 mm and plate thicknesses of 20 mm have proven successful for larger table areas.
  • the plates 12 to 15 each consist of easily editable materials. Pressboard is particularly suitable. However, other types of wood or plastics are also suitable.
  • Recesses 16, 17, 18 are arranged in the plates 12, 13, 14 and 15 at those points which lie opposite the depressions 7, 8, 9.
  • the recesses 16 to 18 each consist of a section 19 with a larger cross-sectional diameter and a section 20 with a smaller diameter.
  • the symbol formed by the respective recess 7, 8 or 9 is illuminated uniformly. Furthermore, the corresponding symbol is clearly visible from the front and from the side.
  • the cross sections of the sections 19 are adapted to the dimensions of the depressions 7, 8 and 9, ie the walls of the sections 19 end at the outer ends of the respective symbol.
  • FIG. 2 shows a segment 24 from the front, which contains a part of a scale plan of an airport section. For example Lanes 25, 26, 27 shown. Furthermore, depressions with circular symbols 28, arrowhead-shaped symbols 29, cross-shaped symbols 30 and ball-shaped symbols 31 are provided.
  • the circular symbols 28 correspond to headlights for marking a path 25 or in a specific geometric arrangement of the start of a path.
  • the arrowhead-shaped symbols 29 indicate headlights for conveying direction information.
  • the cross-shaped symbols 30 correspond to headlights which are intended to indicate a lock when illuminated.
  • the bar-shaped symbols 31 correspond to headlights for marking zones or boundaries.
  • each of the segments 3 to 6 is connected on one end face to a flexible material web 32, which is also connected on one end face of a plate 34 corresponding to the segment 24.
  • the material web 32 is preferably a piece of tissue which can consist of plastic threads.
  • the segment 24 is clearly captively fastened to the plate 34 by the fabric 32, which has recesses 35, 36, 37, 38 in accordance with the symbols 28 to 31 formed in the segment 24 by depressions on the back. The depressions protrude approximately 0.5-1 mm into the respective segment.
  • FIGS. 1 to 3 The structure of an illuminated display device shown in FIGS. 1 to 3 makes subsequent changes to a panel as a result of changes in the system possible quickly and easily. Changes must only be made to those segments that are affected by the changes in the system. These segments can be separated from the feed lines by pulling off the sockets 21. Then e.g. loosened a tension, making the segments 3 to 6 and 24 easy to remove from the panel. At those points of the plan where a new symbol is to be attached, a deepening is made e.g. drilled or milled. A corresponding recess is then also drilled or milled in the associated plate. If you no longer wish to be displayed at any point, the recess is filled with color, which is applied in accordance with the plan.
  • a deepening is made e.g. drilled or milled.
  • a corresponding recess is then also drilled or milled in the associated plate. If you no longer wish to be displayed at any point, the recess is
  • the segment can then be used again in the association. Then the optical fiber bundles are put back into their intended position.
  • the device described above can be used for runway lights, for the parking space occupancy, for the apron lights and for the optical devices for specifying a landing route at the terminal.
