Abstract

The subject of the invention is a method for signalling and for optical guiding by signalling panels. The signalling panel 1 acts as optical guides by using, on its outer face, substances which are sensitive to photofluorescence and phosphorescence, the said panel 1 being excited by WOOD lamps 2; the photofluorescent substances incorporated on the outer faces of the illuminated faces of the panels 1 are generally organic substances of the aromatic series. The said panels 1 apply especially to signalling and guidance in tunnels.

Description

L'invention a pour objet un procédé de signalisation et de guidage optique des panneaux de signalisation faisant office de guides optiques utilisant la fluorescence et la phosphorescence pour la mise en oeuvre du procédé. The subject of the invention is a method of signaling and optical guidance of traffic signs acting as optical guides using fluorescence and phosphorescence for the implementation of the method.

Lesdits panneaux de signalisation ont pour application notamment le guidage optique dans les tunnels et par exemple les passages protégés. Said traffic signs have for application in particular the optical guidance in the tunnels and for example the protected passages.

L'étant de la technique utilise généralement pour les panneaux de signalisation la phosphorescence. The background of the technique generally uses phosphorescence for traffic signs.

L'inconvénient majeur réside dans le fait que la durée d'émission de la phosphorescence est relativement courte. The major drawback lies in the fact that the duration of emission of the phosphorescence is relatively short.

Le procédé selon l'invention réside dans le fait que l'on utilise des panneaux de signalisation comme de véritables guides optiques et ce, en utilisant deux phénomènes connus de la photoluminescence : la photofluorescence et la phosphorescence. Lesdits panneaux sont traités pour que des substances actives à ces deux phénomènes soient intégrées dans leurs faces visibles. The method according to the invention resides in the fact that traffic signs are used as real optical guides, using two known phenomena of photoluminescence: photofluorescence and phosphorescence. Said panels are treated so that substances active in these two phenomena are integrated into their visible faces.

I1 est également possible de mettre en place des nouveaux panneaux traités sur les panneaux déjà en place ou bien de traiter les panneaux existant par des peintures répondant aux caractéristiques de l'invention. It is also possible to install new treated panels on the panels already in place or to treat the existing panels with paints meeting the characteristics of the invention.

A cet effet, lesdits panneaux de signalisation peuvent être de ceux décrits dans la demande de brevet d'invention déposée le 2 juin 1988 sous le nO 86 08013 et ayant pour objet : dispositif de fixation de plaques pour revêtement ou doublage de parois tels que des tunnels. To this end, said traffic signs may be those described in the patent application filed June 2, 1988 under No. 86 08013 and having as their object: device for fixing plates for coating or lining walls such as tunnels.

A cet effet, les panneaux de signalisation sont éclairés par une ou plusieurs lampes de WOOD qui ne laissent passer que les ultra-violets qui viennent exciter la photoluminescence de substances incorporées sur les faces extérieures des faces éclairées des panneaux. To this end, the traffic signs are illuminated by one or more WOOD lamps which only let through the ultraviolet rays which come to excite the photoluminescence of substances incorporated on the external faces of the lit faces of the panels.

Lesdites substances sont en général des substances organiques de la série aromatique, colorants divers. Ces substances photofluorescentes absorbent les radiations ultra-violettes, puis restituent l'énergie sous forme de radiations de longueur d'onde -différente en particulier de radiations visibles. Associés à ces substances photofluorescentes aux ultra-violets, d' autres substances phosphorescentes sont prévues sur ces mêmes faces desdits panneaux de signalisation. Said substances are generally organic substances of the aromatic series, various dyes. These photofluorescent substances absorb ultraviolet radiation, then restore energy in the form of radiation of wavelength -different in particular visible radiation. Associated with these photofluorescent substances to ultraviolet, other phosphorescent substances are provided on these same faces of said traffic signs.

Lesdites substances sont en général des sulfures alcalino-terreux ou de zinc. Said substances are generally alkaline earth or zinc sulfides.

A proximité des panneaux des lampes de WOOD, éclairent lesdits panneaux. Near the panels of the WOOD lamps, illuminate the said panels.

Les avantages de ces panneaux de signalisation sont nombreux. Ainsi en cas de panne de courant électrique notamment dans un tunnel autoroutier, l'ensemble restitue immédiatement l'énergie lumineuse quelques temps après le passage d'un véhicule (six heures environ avec une énergie luminescente décroissante). Cette restitution de l'énergie lumineuse se fait par le phénomène de la phosphorescence. qui évite l'effet de trou noir et assure un balisage complet. The advantages of these signs are numerous. Thus, in the event of an electrical power failure, particularly in a motorway tunnel, the assembly immediately restores the light energy some time after the passage of a vehicle (approximately six hours with decreasing luminescent energy). This restitution of light energy is done by the phenomenon of phosphorescence. which avoids the black hole effect and ensures complete markup.

Les lampes de WOOD n'ont pas un faisceau visible, elles ne gênent donc pas l'automobiliste tout en autorisant par photofluorescence l'éclairage d'une véritable rampe lumineuse qui peut être de plusieurs couleurs et qui guide et informe l'automobiliste. WOOD lamps do not have a visible beam, so they do not interfere with the motorist while allowing by photofluorescence the lighting of a real light bar which can be of several colors and which guides and informs the motorist.

Les dessins ci-joints sont donnés à titre d'exemples indicatifs et non limitatifs. Ils représentent un mode de réalisation préféré selon l'invention. Ils permettront de comprendre aisément l'invention. The attached drawings are given as indicative and non-limiting examples. They represent a preferred embodiment according to the invention. They will allow the invention to be easily understood.

La figure 1 est une vue en perspective de l'entrée d'un tunnel autoroutier pourvu de panneaux de signalisation selon l'invention. Figure 1 is a perspective view of the entrance to a highway tunnel provided with traffic signs according to the invention.

La figure 2 est une vue schématique d'un côté du tunnel autoroutier mettant en evidence les panneaux de signalisation. Figure 2 is a schematic view of one side of the highway tunnel highlighting the traffic signs.

La figure 3 est une vue schématique d'une des parois du tunnel vue en coupe au niveau des panneaux et mettant en évidence l'éclairage desdits panneaux par des lampes de WOOD. FIG. 3 is a schematic view of one of the walls of the tunnel seen in section at the level of the panels and showing the lighting of said panels by WOOD lamps.

Les panneaux de signalisation 1 sont fixés aux parois en utilisant le dispositifde fixation décrit dans le brevet ci-dessus cité. Lesdits panneaux 1 sont revêtus de différentes couches de produits selon les effets optiques que l'on veut obtenir. The signaling panels 1 are fixed to the walls using the fixing device described in the above-mentioned patent. Said panels 1 are coated with different layers of products according to the optical effects which it is desired to obtain.

Au niveau par exemple du plafond du tunnel des lampes 2, telles que des lampes de WOOD, sont disposées pour exciter les substances photofluorescentes des panneaux 1. At the level, for example, of the tunnel ceiling, lamps 2, such as WOOD lamps, are arranged to excite the photofluorescent substances of the panels 1.

L'invention permet donc d'obtenir notamment à l'entrée des tunnels, à l'intérieur et à la sortie desdits tunnels, un guidage optique qui permet de guider par une rampe lumineuse les automobilistes. Ladite rampe lumineuse peut comporter des signes donnant des informations. The invention therefore makes it possible in particular to obtain at the entrance to the tunnels, inside and at the exit of said tunnels, optical guidance which makes it possible to guide motorists by a light ramp. Said light bar may include signs giving information.

Du fait de la présence des substances photofluorescentes et phosphorescentes, il n'y a pas de trou noir pour l'automobiliste en cas de coupure de courant par exemple.  Due to the presence of photofluorescent and phosphorescent substances, there is no black hole for the motorist in the event of a power failure, for example.
