Abstract

Device and method intended to display backlit optional messages. The invention relates to a device and a method making it possible to display backlit messages, and to erase these messages at will. They consist of 1 plate or an opaque layer (1) through which etching (2) is carried out. A light source (3) backlights the etching (2) through the plate or the layer (1) when the light source (3) is extinguished; the translucent but partially opaque plate (4) masks and erases the etched message. The device and the method according to the invention are particularly intended for signalling, information, alarm and advertising.

Description

Titre de 1'Invention : Dispositif et Procédé de réalisation d'Affichages
de messages facultatifs rétro-éclairés.Title of the Invention: Device and Method for Making Displays
backlit optional messages.

La présente invention concerne particulièrement un dispositif et un procédé destinés à l'affichage de messages facultatifs rétro-éclairés, pour informations - signalisations - alarmes - publicités. The present invention particularly relates to a device and a method intended for displaying optional backlit messages, for information - signals - alarms - advertisements.

Elle permet de rendre des messages visibles et de les rendre invisibles pendant des périodes de temps, qui seront prévues ou commandées directement ou indirectement par des systèmes électriques, électroniques, mécaniques ou automatiques. It makes messages visible and makes them invisible for periods of time, which will be provided for or controlled directly or indirectly by electrical, electronic, mechanical or automatic systems.

Les dessins annexés illustrent l'invention. The accompanying drawings illustrate the invention.

La figure 1 représente le dispositif selon l'invention.Figure 1 shows the device according to the invention.

La figure 2 représente une variante selon l'invention.FIG. 2 represents a variant according to the invention.

En référence à ces dessins a) Pour faire apparaître les messages il faudra réaliser une gravure (2) en creux et au travers d'une plaque ou d'une couche (1) opaque ne laissant pas passer la lumière, cette plaque (1) pourra être réalisée en métal, matière plastique, peinture, laque, verre, impression, papier, carton, bois, etc... With reference to these drawings a) To make the messages appear, an engraving (2) must be made in the hollow and through an opaque plate or layer (1) which does not allow light to pass through, this plate (1) can be made of metal, plastic, paint, lacquer, glass, printing, paper, cardboard, wood, etc ...

b) une source lumineuse (3) placée à l'arrière de la plaque (1) projettera la lumière à travers de la gravure (2) et fera apparaître le message sur l'avant de la plaque (1).b) a light source (3) placed at the rear of the plate (1) will project the light through the engraving (2) and will make the message appear on the front of the plate (1).

c) Pour faire disparaître le ou les messages, lorsqu'il sera jugé nécessaire, il faudra éteindre ou supprimer la source lumineuse (3). c) To make the message (s) disappear, when it is deemed necessary, the light source (3) must be turned off or removed.

d) Pour obtenir l'effacement complet des messages, il faudra ajouter une plaque (4) qui sera assemblée ou plaquée devant la plaque (1) cette plaque (4) devra être translucide, à la lumière, mais opaque, sans le rétro éclairage afin de masquer les messages gravés (2) non rétro-éclairés..d) To obtain the complete erasure of the messages, it will be necessary to add a plate (4) which will be assembled or plated in front of the plate (1) this plate (4) must be translucent, in the light, but opaque, without the backlight to hide non-backlit engraved messages (2).

Pour obtenir cette propriété la plaque (4) devra avoir une épaisseur assez faible voir 1/10 à 5/10 de millimètre, selon les matériaux utilisés. To obtain this property, the plate (4) should have a fairly small thickness, see 1/10 to 5/10 of a millimeter, depending on the materials used.

e) Suivant la figure 2, il est possible d'obtenir des messages rétro-éclairés de couleurs différentes.e) According to FIG. 2, it is possible to obtain backlit messages of different colors.

Suivant l'intensité de la luminosité du message que l'on voudra obtenir, il est possible d'utiliser, soit la lumière ambiante, soit des lampes, des flammes, des ampoules d'éclairage ou des leds luminescentes de différentes couleurs. Depending on the intensity of the brightness of the message that we want to obtain, it is possible to use either ambient light, or lamps, flames, light bulbs or luminescent LEDs of different colors.

Cependant dans le cas de sources lumineuses à lumière blanche, la coloration pourra se réaliser en intercallant une feuille (5) de matière transparente colorée entre la source lumineuse (3) et la plaque (1). Cette feuille colorée (5) pourra être en matière plastique, papier, peinture, en impression ou en verre. However, in the case of white light sources, coloring can be achieved by interposing a sheet (5) of colored transparent material between the light source (3) and the plate (1). This colored sheet (5) may be made of plastic, paper, paint, printing or glass.

Le dispositif et procédé selon l'invention sont particulièrement destinés à l'affichage de messages facultatifs pour l'information dans les véhicules de transport en commun, dans les cabines et commandes d'ascenseurs, les lieux publics - gares - aéroports, magasins, super-marchés - salles de spectacle, signalisation routière, etc...  The device and method according to the invention are particularly intended for displaying optional messages for information in public transport vehicles, in elevator cabs and controls, public places - stations - airports, shops, super -market - performance halls, road signs, etc ...
