    Light signaling panel
    Technical field of the invention
    The present invention relates to a light signaling panel.
    The invention can be implemented for many applications, which in particular require thin, flexible and / or particularly robust elements to withstand shocks, high mechanical loads or to resist vandalism.
    It thus finds a preferred, but not limiting, application in areas welcoming pedestrians, bicycles or all types of vehicles, for example roadways, sidewalks, station platforms among others.
    State of the art
    There are many lighting solutions, offering luminous boxes to be embedded in a housing made in a wall or in a floor. This is for example the case of the solution described in patent application CN201382393U or in patent application EP2803911A1.
    Patent application WO2016 / 016484A1, for its part, offers a solution integrated into the roadway and extending the white stripes of a pedestrian crossing, thus making it possible to strengthen the signaling around the pedestrian zone.
    Many other solutions have been proposed to signal or warn using light blocks integrated into the road.
    However, most of the known solutions propose very thick light blocks. Admittedly, this high thickness can make the block more robust and more resistant to mechanical stresses, but its installation can prove to be more difficult, often requiring infrastructure work.
    In addition, by their size and characteristics, these light units are limited to occasional use and have neither the mechanical characteristics, nor the adhesion characteristics required for use under traffic, nor the ability to resist vandalism.
    When a light signaling zone is integrated directly into the road to alert of the presence of a danger zone, the light signaling architecture must, however, be reliable. This architecture must have qualities of:
    Reliability to operate regardless of mechanical or climatic constraints;
    Mechanical resistance to withstand pedestrian, cycling, or automobile traffic of all types;
    Flexibility to be easily positioned on a flat layer or not;
    - Grip to recreate the roughness characteristics of a classic traffic area such as a roadway;
    Finesse in particular to allow its flexibility, limit the overall height, be easily positioned on an existing pavement without modification or substantial work;
    - Visibility to always ensure signaling, whatever the atmospheric conditions, in particular in the event of fog or rain;
    The object of the invention is therefore to propose a light signaling slab forming at least partially a trafficable zone and having the qualities described above.
    Statement of the invention
    This object is achieved by a one-piece light signaling slab comprising a structure with several superimposed layers and fixed together, said structure comprising:
    A first transparent or translucent layer forming a front face of said slab;
    A light assembly comprising a plurality of light emitting diodes electrically connected to each other;
    An assembly encapsulating said plurality of light-emitting diodes;
    A second layer forming a rear face of said slab and composed of a polymer / glass fiber composite material;
    Said encapsulating assembly being positioned between said first layer and said second layer.
    According to a particular feature, each plate of the first layer is positioned opposite at least one light-emitting diode.
    According to another particular feature, the first layer is made of a polymer type material chosen from polycarbonate, polymethyl methacrylate, ethylene tetrafluoroethylene and polyvinylidene fluoride.
    According to another feature, the first layer has a thickness greater than 100 μm, advantageously between 200 μm and 3000 μm and preferably between 400 μm and 750 μm.
    According to another particularity, the second layer has a rigidity defined by a Young's modulus at room temperature greater than 1 GPa.
    According to another particular feature, said second layer has a thickness of between 1 mm and 3 mm.
    According to another particular feature, the encapsulating assembly is made of a material having a Young's modulus at room temperature greater than 50 MPa.
    According to another particular feature, said encapsulating assembly has a thickness of between 100 μm and 4 mm and advantageously of between 250 μm and 1 mm.
    According to another particularity, the multilayer structure comprises at least one intermediate layer, arranged between said first layer and the encapsulating assembly and configured to carry out the assembly by bonding of said first layer on the encapsulating assembly.
    According to another particular feature, said intermediate layer is made of one or more materials chosen from polymers of the rubber, elastomer or epoxy type.
    According to another particularity, the intermediate layer is configured to present a Young's modulus at ambient temperature less than or equal to 100 MPa.
    According to another particular feature, said intermediate layer has a thickness of between 200 μm and 1600 μm.
    According to another particular feature, said structure comprises an adhesive layer situated on the rear face, in contact with the second layer.
    According to another particular feature, said structure comprises a wearing layer applied to said first layer, said wearing layer being non-opaque and having a textured and irregular surface.
    The invention also includes an infrastructure comprising a trafficable zone provided with a support layer, said infrastructure comprising several light signaling tiles as defined above, fixed on said support layer, said tiles being positioned so as to form a marking on said walkable area when their light assembly is on.

    Figure 1 shows, in perspective view, a light signaling slab according to the invention;
    Figure 2 illustrates, in a sectional view, the multilayer structure of the light signaling slab of the invention;
    Figure 3 illustrates, in a sectional view, an example of arrangement of light signaling tiles on a roadway;
    FIGS. 4A and 4B represent two examples of implementation of the light signaling tiles in accordance with the invention;
    Detailed description of at least one embodiment
    In the following description, without implied limitation, by traffic zone is meant any zone intended for the circulation of pedestrians and / or bicycles, and / or vehicles, such as for example a road or highway type roadway, a bike path, a sidewalk, a dock or a parking lot.
    The invention relates to a light signaling slab, which can also be called lighting slab 2. It is for example intended to form all or part of a traffic area The traffic area formed may include one or more light signaling tiles positioned so adapted to define at least one light marking on the trafficable area when their light assembly is activated. The slabs 2 can be positioned contiguously or isolated from each other, depending on the marking or the lighting element to be produced.
    In the following description, the terms front, rear, upper, lower, top, bottom or other equivalent terms are to be considered taking into account an axis (A) which will be defined as perpendicular to the plane formed by a slab (axis vertical in the plane of the sheet in the appended figures).
    The light signaling slab 2 can be positioned so as to cover at least in part the surface of a support layer 1, this support layer 1 can for example be the existing pavement or a lower layer thereof, after removal of the wearing course. This support layer 1 is for example composed of a mix. Of course, this support layer 1 not forming part of the light signaling slab, any other monolayer or multilayer structure could be envisaged. This support layer 1 can be part of the overall infrastructure which will be described below.
    The invention aims in particular to produce a functional light signaling or lighting layer using one or more light signaling tiles positioned so as to cover at least partially the upper face 10 of the support layer 1.
    Referring to Figure 1, a light signaling slab 2 of the invention has the characteristics described below.
    The slab 2 of the invention is in the form of a one-piece element, that is to say forming only one piece. It advantageously has a first face, called the upper face F1, intended to form its outer face and a lower face F2 opposite and preferably parallel to the upper face. Between its two faces, the slab has several layers. Slab 2 can have an outline of any possible shape depending on its application. The slab can in particular be of rectangular or square shape, for example of dimensions equal to 20 cm × 20 cm. Of course, depending on the type of signaling to be carried out, it may have other dimensions. By way of example and without limitation, it can be 0.1m x 1.5m or 0.1m x 3m in a discontinuous line type application on a road, 0.5m x 1.2m or 0.5m x 2.4 m in the case of a pedestrian crossing type application.
    With reference to FIG. 2, from the front to the rear, each light signaling slab 2 can comprise a multilayer structure as described below. Some of the layers described below may be optional.
    First layer before
    The first layer 200 comprises one or more juxtaposed transparent plates or films. The production in several juxtaposed plates or films makes it possible to manage the thermal expansion constraints during the use of the slab outdoors. The expansion being proportional to the dimensions of this first layer, using plates of appropriate dimensions makes it possible to adapt to thermal constraints and to avoid the appearance of phenomena of the delamination or deformation type.
    The first layer 200 is made of a transparent or translucent material so as to allow a light flux to pass.
    By the term transparent, it is meant that the material forming the first layer is at least partially transparent to visible light, allowing for example at least 80% of visible light to pass.
    By the term "translucent" is meant that the material forming the first layer allows the transmission of visible light in a diffuse manner.
    Furthermore, the first layer can be tinted in any color, depending on the intended application.
    The first layer 200 can be made of a polymer type material chosen from polycarbonate (PC), polymethyl methacrylate (PMMA), ethylene tetrafluoroethylene (ETFE) and polyvinylidene fluoride (PVDF). Advantageously, it will be a polycarbonate type material.
    The first layer 200 may have a thickness greater than 100 μm and advantageously between 200 μm and 3000 μm and preferably between 400 μm and 750 μm.
    Without limitation, the first layer 200 is composed of a polished polycarbonate film, treated against ultraviolet rays and with a thickness of 450 μm.
    Each plate of the first layer 200 can be positioned opposite one or more light-emitting diodes Ds of the light assembly described below.
    Bright set
    The light assembly 201 is composed of several light-emitting diodes Ds connected in series and / or parallel.
    Light emitting diodes Ds can emit in different colors.
    Conversion means can be used to emit in a desired shade.
    The same light signaling panel 2 can emit light signals of several colors (either by using light-emitting diodes with the desired colors or suitable conversion means).
    Depending on the desired light density, the light-emitting diodes Ds can be spaced from a distance ranging from 0.5 cm to 30 cm and preferably from a distance between 0.6 cm and 15 cm.
    The light-emitting diodes Ds can be assembled in strips or on a support making it possible to supply the diodes and comprising strips of conductors on epoxy or kapton on which the light-emitting diodes Ds are connected. On the same ribbon, the diodes Ds can be spaced apart by a pitch of between 0.5 cm and 10 cm and preferably between 1 cm and 3 cm. The inter-ribbon distance can be between 1 cm and 30 cm and preferably between 2 cm and 15 cm.
    This diode support can complete the second rear layer 203 described below or replace this layer. In FIG. 2, the rear layer 203 acts as a support.
    The support may have a thickness between 0.1 mm and 5 mm, advantageously between 0.1 mm and 2 mm, ideally between 0.15 mm and 1.5 mm.
    Means for controlling the lighting of the diodes Ds, located in the panel and / or centralized in an external box, are of course provided for controlling the light assembly 201 in a manner suitable for the signaling to be carried out. These control means may include a programmable controller comprising inputs / outputs. The PLC can receive information from various sensors on its inputs and appropriately controls the light signaling panels connected to its outputs.
    Advantageously, the spacing between two neighboring plates of the first layer 200 is less than or equal to the spacing between two neighboring light-emitting diodes Ds. Thus, at least each plate of the first layer 200 is placed opposite at least one light-emitting diode Ds.
    Encapsulating assembly
    The structure comprises an encapsulating assembly or housing in which the light-emitting diodes Ds are encapsulated.
    By the term encapsulating or encapsulating employed, it should be understood that the light-emitting diodes Ds are housed in a volume, preferably hermetic.
    It makes it possible to fill the spacing present between the light-emitting diodes Ds of the light assembly 201.
    The encapsulating assembly may include an upper part 202a and possibly a lower part 202b.
    The upper part 202a is positioned between the first layer 200 and the light assembly 201.
    The upper part 202a forms a mechanical protection such as a shell on the light assembly.
    The upper part 202a can have a level of rigidity expressed by a Young's modulus at room temperature greater than 50 MPa.
    Advantageously, the upper part 202a of the encapsulating assembly is made of an ionomer type material having a Young's modulus greater than 300 MPa.
    In a particular embodiment, the lower part 202b of the encapsulating assembly is located between the light assembly 201 and the second layer 203 described below.
    The lower part 202b forms a mechanical protection and a barrier to water or humidity liable to rise from below the slab.
    The lower part 202b may include a level of rigidity expressed by a Young's modulus at room temperature greater than 50 MPa.
    Advantageously, the lower part 202b of the encapsulating assembly is made of an ionomer type material having a Young's modulus greater than 300 MPa.
    Each element produced in the form of a film intended to form the upper part and possibly the lower part of the encapsulating assembly may have a thickness of between 0.1 mm and 2 mm, ideally between 0.3 mm and 1, 5 mm.
    In its entirety (one or two layers), said encapsulating assembly may have a thickness between 100 μm and 4 mm and advantageously between 250 μm and 1 mm.
    Second back layer
    The second layer 203 forms the lower layer of the structure and constitutes the support for the light signaling slab 2.
    This second layer 203 is made of a material intended to provide mechanical protection against rear punching of the electronic circuits of the light assembly 201 when the light signaling slab 2 is subjected to a significant mechanical load.
    The second layer 203 can be provided with a rigidity expressed by a Young's modulus at room temperature greater than 1 GPa, advantageously greater than or equal to 3 GPa, ideally greater than 10 GPa.
    The second layer 203 is however flexible enough to adapt to the deformations of the support layer 1 of the roadway.
    The second layer is flexible enough to conform to the deformations of the roadway (hump or hollow of 1 cm every 20 cm, advantageously hump or hollow of 0.5 cm every 20 cm, ideally hump or hollow of 0.2 cm all the 20 cm).
    The second layer 203 can be made of a transparent or opaque material, and optionally tinted, for example in the mass or on the surface in particular to define a pattern.
    The second layer 203 may have a thickness of between 0.1mm and 10mm, advantageously between 0.4mm and 5mm, advantageously between 1mm and 3mm.
    The second layer 203 can be produced in a polymer material, in a composite material of the polymer / glass fiber type or in a material of the family of thermosetting polymers, such as resins of the phenolformaldehyde type.
    Without limitation, the second layer 203 can be composed of a composite material of the polymer / glass fiber type such as a fabric based on polyethylene terephthalate, polypropylene or polyepoxide and glass fibers with a rate glass fibers, for example between 20% and 70% by mass.
    This second layer 203 may have a coefficient of thermal expansion less than or equal to 20 ppm, preferably less than or equal to 10 ppm.
    Compatibility and protection layers
    The structure may include one or more layers of compatibility and protection, called intermediate layers.
    In one embodiment, the structure may include a first intermediate layer 204 positioned between the first layer 200 and the upper part 202a of the encapsulating assembly.
    The structure may also include a second intermediate layer (not shown) positioned between the second layer 203 and the lower part 202b of the encapsulating assembly.
    Each of these intermediate layers may be necessary in the event of chemical incompatibility between the first layer and the second layer and the encapsulation material.
    Each intermediate layer can be produced in a standard encapsulating material and chosen, for example, from a rubber or elastomer type polymer such as ethylene vinyl acetate (EVA), a polyolefin, silicone, a thermoplastic polyurethane and butyral polyvinyl. It can also be produced from a liquid resin of acrylic, silicone or polyurethane type (mono-component or two-component), crosslinkable hot or cold.
    Without limitation, by way of example:
    For the first intermediate layer, it may be the combination of one or more EVA films having a total thickness of between 200 μm and 1600 μm;
    For the second intermediate layer, it may be one or more films in TPU) having a total thickness of between 200 μm and 1500 μm;
    The first intermediate layer 204 may have deformability properties in order to give the slab a certain level of damping. In this case, this layer will have a double function of compatibility and damping. It will also fill the gap between the light-emitting diodes Ds.
    Each intermediate layer may have a rigidity defined by a Young's modulus at room temperature less than or equal to 100 MPa.
    Each intermediate layer may have a thickness of between 0.01 mm and 1 mm.
    Adhesive layer of the slab
    The structure may include an adhesive layer 205 situated on the rear face of the slab and in contact with the second layer 203 and making it possible to adhere the slab to the surface 10 of the support layer 1. This adhesive layer can be formed of an adhesive or of an adhesive polymeric material, for example of the double-sided type.
    This adhesive can be an adhesive making it possible to adhere the slab to the support layer 1. This adhesive can be based on MMA resin (Methyl Methacrylate), optionally additive with fillers, or of bituminous type, applied to dosages ranging from 0.5 to 10 kg / m 2 .
    The use of an adhesive associated with the second layer 203 made of composite material can make it possible to reinforce the rear face of the panel and avoid the risks of punching of the light-emitting diodes Ds when they are subjected to high mechanical loads.
    Tread layer
    The wearing course can cover one or more light signaling tiles. For a single slab, it can cover all the plates of the first layer continuously or cover each plate independently, forming discontinuities on slab 2.
    For each slab, the wearing course 206 covers the first layer 200 to give the slab 2 a certain roughness and adhesion characteristics.
    The wearing course 206 can be composed of a transparent or translucent resin and irregular texturing elements making it possible to give the slab a certain adhesion, even in wet conditions.
    The resin can be of acrylic, epoxy or polyurethane type. The resin can be deposited with a dosage of between 10 and 1000 g / m2, advantageously between 30 and 700 g / m2, advantageously between 150 and 600 g / m2.
    The wearing course is optionally added with a colored substance (for example a white or yellow road paint, or even TiO2 pigments, or a yellow paint), to which transparent or colored texturing elements are added, for example grains of glass, with a size between 0.01 and 4 mm, better between 0.1 and 2 mm, ideally between 0.2 and 1.8 mm. The dosage of these glass grains is between 10 and 800 g / m 2 , better 30 and 500 g / m 2 , ideally 50 and 400 g / m 2 . The colorimetry can be measured according to standards NF EN 1871 or NF EN 1436, and be included in the chromatic perimeter of a marking, for example the standard NF EN 1436 + A1 for a white road marking.
    The coating layer may have a transparency rate making it possible to pass at least 10% of the light flux generated by the light assembly 201, advantageously 50% to 95% of the light flux generated by the light assembly 201.
    Taking into account the different layers described above, advantageously, a light signaling slab 2 can comprise the following multilayer structure, going from the front to the rear of the slab:
    A first layer 200 formed of a film 450 μm thick made of polished polycarbonate and treated with UV protection;
    A damping layer 204 formed of one or more EVA films having a thickness chosen between 200 and 1600 μm and of one or more thermoplastic films in TPU at a thickness between 200 μm and 1500 μm;
    An upper layer 202a of encapsulant formed of an ionomer having a stiffness defined by the Young's modulus greater than 300 MPa and chosen at a thickness of between 100 μm and 500 μm;
    A light assembly 201 composed of light-emitting diodes Ds assembled in strips or on a printed circuit, with a spacing between diodes which can range from 0.5 to 30 cm;
    A second layer 203 formed on the back and composed of a fabric-type composite polymer based on polyethylene terephthalate, polypropylene or polyepoxide and glass fibers with a content of glass fibers, for example between 20 % and 70% by mass and preferably between 50% and 70% by mass, having a thickness of 1.5 mm and a Young's modulus equal to 12 GPa.
    A wearing course 206 as described above;
    According to a particular aspect of the invention, each tile 2 can, depending on its state, have a distinct color. So :
    When its light assembly 201 is off, its color may be dark, of a color close to that of the rest of the roadway. In this case, the second rear layer 203 and / or the support of the light assembly can be colored in this dark color. When the slab is off, nothing distinguishes it from the rest of the road.
    When its light assembly 201 is off, its color can be clear, for example white or yellow. The lighting of its light assembly then makes it even more visible. In this case, the second rear layer 203 and / or the support of the light assembly can be colored in this white or yellow color. When the panel is off, the marking remains visible. This solution keeps the marking visible, even in the event of a slab malfunction.
    Of course, depending on the intended applications, any other color can be envisaged, whether in the active or inactive state of the light signaling panel.
    According to another aspect of the invention, the light-emitting diodes can light up in several distinct colors to produce dynamic displays on a roadway. In a nonlimiting manner, it can be indications of speed limit (for example modified according to the climatic conditions), indications of parking spaces for delivery (red on a certain time slot and green the rest of the time) , Zebra type indications for bus stop (changing color depending on the waiting time to be expected) or any other marking.
    According to one aspect of the invention, as shown in FIG. 3, one or more light signaling tiles 2 as described above can be positioned on the surface 10 of a support layer 1 in order to form a passable area. Said slabs can form all types of marking or message, usually present on a trafficable area, in particular:
    - Marking forming a continuous or broken line on a road; Pedestrian pathway ;
    - Zebra delimiting a stop zone, for example for taxi or bus;
    - Edge marking signaling a danger zone;
    - Speed signs on the road;
    - Marking to signal a slowdown zone, a danger;
    - Guide marking;
    Precise indications of the timetable for the passage of the next bus or the waiting time to be expected;
    Information, cultural, advertising information;
    FIGS. 4A and 4B illustrate some examples of marking which it is possible to carry out using one or more light signaling tiles in accordance with the invention. In FIG. 4A, the light marking 30 consists of a speed signal to be observed, indicating that it is possible to travel on this lane at the speed indicated. In FIG. 4B, the light marking 31 consists of signaling a danger.
    One or more light signaling tiles can be ordered sequentially to create chaser-type effects or with variable intensity.
    The light signaling slab 2 thus has a number of advantages, among which:
    A very small thickness, which can be less than 10mm;
    Significant mechanical resistance to support any mechanical load, in particular the passage of cars or trucks;
    A high degree of flexibility, allowing it to adapt to the surface defects of its support layer 1;
    A high level of lighting, ensuring efficient signage in all situations;
    Increased weather resistance thanks to suitable encapsulation of electronic circuits;
    - Thanks to its low thickness, easy installation, even on an existing pavement;
    The light signaling slab has been described above for an infrastructure comprising a traffic area provided with a support layer (1). However, the invention can be implemented for many other applications, in particular any application which requires thin, flexible and / or robust elements with respect to shocks or mechanical loads or to resist vandalism.
