Abstract

Device for display by optical fibres 2 by projection or otherwise 9, onto a support 8 bringing together the fibres, forming a sort of frame and allowing viewing of any images or information, in colour or otherwise, fixed or animated, and enlarged on an external or internal panel 1 of the required size, by virtue of the transmission of light points by these same fibres 2, and capable, for that reason, of being viewed from a remote point.

Description

The invention relates to a display device 8 optical fibers, for advertising, signs, signaling, or the like, comprising optical fibers by so much of an area near a light source and whose ends, distant of the light source, are arranged in one or more lines corresponding to information to be displayed
The object of the invention is above all to make display devices of this kind such. that they meet better than before the various requirements demanded by a greater variety of information
According to the invention a fiber optic display device, of the kind defined above, is characterized by the fact that it comprises a support on which is provided the fixing of a certain number of optical fibers remote from the light source , allowing the vision of information, reading. animation t etc, enlarged, and therefore able to view from a distance
At the other end, the optical fibers are assembled in an orderly order, in a tight bundle forming a sort of frame, and serving as a screen on which the projection allows, via optical fibers, the transmission of images or these connes , information to transmit
Generally the support used for the reader of information, is formed by a plate pierced with the necessary number of holes, making it possible to accommodate the ends of the optical fibers
The fiber optic density is important enough to allow good vision and information
The set of fibers gathered together Cri a bundle as shown above; high, and joined so as to form a flat and polished surface, allowing projection, using a projection apparatus, of a document, of any kind, transparent or not, films, slides , empty, etc ..., by direct or indirect projection of caches, pochers, or the like, or even of small objects, by the intermediary of a camera with objective, episcope kind or the like.

The projection will be made on the face of these fibers gathered, and the information will be conducted by the EU intermediary. ' optical fibers (3) at the other end of said fibers on the outer plate (2) of the device (1)
on the plate (2) the spacing and fixing of the fibers will be studied according to the approximate reading of the message
This spacing will be all the greater as the device is distant from the observation point.
The surface (4) serving as an emission screen for projection, can be protected from stray light by the addition of a dark colored tip.

The light source may be a source suitable for emitting lightning
light such as a flash device or a discharge lamp, in particular with Xenon, or a combination of several light sources, halogen, Xenon, etc.

The support (1) can be made of materials of different types, and
also reflectorized or not.

The invention consists, apart from the arrangements set out above,
certain other provisions which will be more explicitly discussed below
about an embodiment described with reference to the attached drawing, but which
is in no way limiting.

Figure (1) of this drawing is a schematic view in
perspective of a display device according to the invention
Figure (2) shows on a larger scale, a detail of the
figure 1)
The figure (3), finally, is the section of an optical fiber (3)
Referring to the drawing in particular in Figure (1), we
may steal a kn \ fiber optic display device intended for advertising,
it is obvious however that a display device of the same type could be
uses for all kinds of information, for advertising, signage,
signs or the like.

Optical fibers (3) sheathed or not, multi-strand or single-strand
starting from an area (4) adjacent to a light source (9) whose ends (6) of the
elongated fibers from the source (9) are arranged along necessary lines, to
a good definition of the information to display
The ends (7) of the optical fibers located in the vicinity of the
source (9), are assembled so as to form an end piece (4) illuminated by the
source (9), when lit: each fiber conducts light towards its
end (6), and towards the outside, following the direction of the axis of the end of
the fiber.

A transparent disc which can carry an indication or a translucent colored disc having several sectors of different colors can be placed between the end piece (4) and the light source (9) and rotated by a motor so that the end (6) emits a changing color light
An observer looking at these ends (6) will be able to see the information in changing colors
The display device (A) comprises a support formed by a plate t (2)) on which are housed and fixed the ends (6) of the fibers (3), at points arranged along several lines.

 The fixing of; extremities can be ensured either by gluing, or by means of end caps, or by any other fixing means.

 ba plate (2) can be made of plastic, metal, glass or any other suitable material. This plate (2) can be used to close a box (1) inside 1 of which is the multibranch bundle of optical fibers (3) and the light source. The optical fibers and the light source, which can obviously be outside them and distant from the box.

 Day and night the information is visible thanks to the great uminosite these optical fibers when the light source is on.

The information can be fixed, animated, ignoring, or change color as explained above.
The display device does not cause any discomfort in the vicinity of the Sa, t that the fibers 3j are directional and that the light exiting through the ends (6) is mainly directed towards the possible observers

Claims (4)
