FR2488709A1 - Large illuminated advertising display panel - uses optical fibres to carry light to array of elements constituting panel and having pyramidical prismatic configuration - Google Patents

Abstract

The display panel uses a projector to form an image of the display on a screen (1). The surface of the screen is made up of a matrix of points, each of which is the receiving end of an optical fibre. Each optical fibre is connected to a corresponding point on a large external display panel forming part of a magnified image of the display. A second panel (2) is made up of a large number of square section cones (3), with the optical fibre introducing light at the smaller end of the cone. Light spreads out in the cone so that the larger end is fully illuminated. The large end has a square base pyramid surface to give out light. The sides of the conical elements may be coated with a silver coloured synthetic material to increase internal reflection of light and thus enhance the intensity of light on the main display panel.

  Luminous point allowing the creation of an advertising newspaper in

  colors, and bright advertising in colors.

  The present invention relates to the use of fiberglass or

  optically, in an advertising device and more particularly in a

  Positive display improved in 4colors.

  In devices of this kind, the point of light is the point that gives the end of the fiberglass or optical cable, either on a

  semi-transparent screen. This bright point is of inconvenient use.

  One of the aims of the invention is to create a light point that can transmit the colored light in its own screen, a dimentien

  greater than twenty millimeters on one side, and being in contact on the outside.

  We know that the use of glass or optical fibers, trans-

  put the power of light waves that we give at the beginning, with very

  little loss for small distances.

  The invention allows a multiplication of the luminous point, by creating a transparent body of elongated shape, fig. 1 No. 1, having two largest quadrangular bases forms a patterned screen in the form of

  pyramidal prism, fig. 1 n 2, the elongated body acts as a reflection of

  tower, fig. 2 nO 3, the smaller base is intended to receive the connection of the cable end of the fiberglass or optical fiber, fig.

2 do not 1.

  In this description we used quadrangular as title

  example, the more faces in the pyramid prism part, the more

we multiply the luminous points.

  For the use and formation of figures or letters, it is necessary that the light spots are arranged in checkerboard on the entire surface of the billboard; the body of the luminous point is of a great transparency. In the part which acts as a reflector, fig. 2 ne 3, a material in synthetic resins of silver color, can by molding maintain all of the points of light, and give

  greater power to the reflector of the light spots, fig 2 no 2.

  Thus one obtains a plate where all the screens of the luminous points are placed in checkerboard horizontally and vertically. The whole forms the main screen of the billboard, and, is directly in

contact with the outside.

  On the inside we have all the light points receivers. A cavity in the center of the receiving point allows the connection of cables

conductors of light waves.

  For the realization of the luminous advertising in color with continuous passage of figures or letters. The color of the background of the figure or letter,

determine the figure or the letter.

  For this realization, a small light wave receiver is used.

  This receiver is composed of cavities where the ends can be connected.

  mated glass or optic cables, this receiver should be mini- turized as much as possible and should keep the same configuration as the display.

  principal, it should have the same amount of horizontal cavities and ver-

  ticals-that the main screen, fig. 3.

  This receptor can be made with synthetic resins, non-trans-

  parents to allow good isolation of the receiving points.

  The fiberglass or optic cables are cut and prepared for

  be connected at each end, one end to the luminous point of the

  main and the other at the reference cavity of the receiver.

  Once all the cables are connected, the receiver is placed in its place in front of reflecting lamps without cliché, if we turn on the lamps the luminous flux will invade all the reception points of the receiver, and by the fiberglass or optic cables, all the bright spots of

  the main screen will be illuminated and the billboard will be illuminated

  born in white, that is to say without image.

  To obtain the formation of the figures or letters it is necessary to realize a color contrast. To obtain this contrant, is necessary

  a cliché printed with small transparent colored circles, to allow

  to put the filtering of the light waves into colored waves, fig. 3 ne 1, representing the figure or letters that we want to show on

the main screen.

  This principle of cliché programmed and printed with texts and colors, by the passage in front of the receiver allows each circle printed in color, to realize the animation of the invention. This principle can be used for

  production of a colored advertising newspaper, the program

  In the middle of all the panels represented by the text, the cables of the glass or optical fibers will be longer at the ends, the tape will be of the desired length, or on a fixed or interchangeable plate. Another variant of the invention will allow the use of the main screen, without the aid of fiberglass or optics by illumination of

  the interior of the panel, and the passage of a band with colored circles trans-

  parents and programmed, or a snapshot.

  A complement to the invention will be a trapezoidal crystalline body

  zoldal placed between the lamps emitting luminerx flow and the cliché

  programmed, to propagate the luminous flum of the emitting lamps.
