Description

The present invention relates to the field of light and more particularly relates to a luminous glass unit by guided light extraction in a glass. It is known to form a luminous glazing by illuminating a glass by the wafer with a light source such as a set of light-emitting diodes. The light thus injected is guided by total internal reflection inside this glass thanks to the refractive index contrast with the surrounding materials. This light is then extracted using means that are conventionally a diffusing layer. Naturally, the diodes can be controlled to provide via the scattering pattern a continuous or flashing light zone or changing color.

The Applicant proposes to widen the range of available light glazings based on a lightguide light by the wafer by making possible the simultaneous vision of a first light zone of a first color visible only from the first side of the glazing and d a second light zone of a second distinct color visible only on the other side of the glazing.

The glazed assembly according to the invention guarantees the independence of the two lights (first and second extraction surfaces in full or partial overlap or staggered), particularly switchable to form the signaling of an access door: instant t0: access color, such as green, of a first side and waiting color, such as red, of the second side, - at time t ': inversion of the signaling, stop color of the first side and passing color of the second side.

In another signage application, for a train compartment, one may have written "free" in green on one side and "reserved" in red on the other side or for a separation between a family space or a space classical, we can have families of light with motifs for children (geometry, color, etc.) and a softer light on the classic side (and / or one or more more sober light patterns), for example a warm white. In an application partition between two spaces (building, outside, in a vehicle including public transport ..), each space can have one or more bright patterns of color, switching type (and shape) adapted and a function adapted decorative or (more) functional (lighting).

For example, it may be a partition between two offices, between two rooms or living room and another space in a shop; it may be partition wall space, including rays, for example totems or a fitting room. On one side, the lighting can be decorative and on the other functional side. For a closet door or door preferably bathroom cabinet mirror, the outer side light may be colored and the inner side white. For each side (or space), the color can change depending on the time of the day (or seasons) as the intensity. Source control (on each side) can be automatic and / or manual. Preferably, the first extraction surface occupies at most 80% and even at most 50% of the internal surface or even at most 20% and / or the second extraction surface occupies at most 80% and even at most 50%. % or at most 20% of the bonding face. A product (intermediate) corresponding to the luminous glazed assembly according to the invention without the first and / or second light extraction means can be sold to the end user or customer who can himself perform the first and / or 10 second means for extracting light, in particular erasable (ink) or removable (sticker). In the configuration i) the opaque masking means may comprise (preferably consist of): - a first opaque masking layer (coating such as a paint, inorganic and / or organic, mono or multilayer) covering and (preferably directly ) on the first reflective layer opposite to the inner face - and / or a second opaque masking layer (coating as a paint, inorganic and / or organic, mono or multilayer) covering and (preferably directly) on the second reflective layer opposite to the bonding face. These opaque masking layers absorb the refracted rays by the underlying reflective layers-having non-zero TL but as small as possible for guiding and extracting efficiency.

In a first embodiment, preferably, the first reflective layer comprises (consists of) a first layer of silver, even more preferably silvering (forming a mirror), preferably directly on the internal face, preferably of at least 30nm, 40nm and even at least 60nm and more preferably at least 90nm (and more preferably at most 120nm), and said RL being at least 60% even at least 85% or 90% (and even said TL being at most 2% and even at most 1% and even at most 0.5% or 0.05%) and a paint, in particular for protecting the silver layer, is (especially directly) on the silver layer (and preferably in contact with the first lamination interlayer) optionally forming (if necessary) a first opaque masking layer.

And the second reflective layer (identical or similar to the first reflecting layer) comprises (consists of) a silver layer, called a second silver layer, even more preferably a silvering (mirror) preferably directly on the bonding surface, preferably at least 30 nm, 40 nm and even at least 60 nm and better still at least 90 nm (and better still at most 120 nm), and said second RL being at least 60% even at least 85% or 90% (and even said second TL being at most 2% and even at most 1% and even at most 0.5% or 0.05%) and particular protection paint of the second silver layer is (especially directly) on the second layer of silver (and in contact with the first interlayer of lamination) optionally forming (if necessary) a second opaque masking layer (the same or similar at the first opaque layer).

These reflective layers form a mirror creating a trompe trompe effect ('' '' '' '' 'eye' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' '' simple because it does not complicate the traditional foliation .

For each glazing, the silvering can be deposited full face. The masking layers are preferably deposited by liquid means. The paints (opaque masking layers) preferably completely cover the surface of the laminated glazing for simplicity and optimum efficiency. Alternatively, in the configuration i), the opaque masking means 20 comprise (consist of) an opaque element (very absorbent preferably) preferably monolithic and single. It may be: an opaque film in the mass, in particular a tinted plastic, spaced from the first and second reflective layers between the first transparent laminating interlayer in contact with the first reflecting layer and the first surface of extraction and a second lamination interlayer (transparent) in contact with the second reflecting layer and the second extraction surface. an opaque layer such as a paint (lacquer) or enamel on the additional transparent substrate (thin film, particularly flexible plastic such as a polyethylene terephthalate, called PET, or glass) between the first laminating interlayer selected transparent contact with the first reflective layer and the first extraction surface and a second laminate interlayer (transparent) in contact with the second reflective layer and the second extraction surface - an opaque layer on the first interlayer of laminating chosen transparent as a paint (lacquer ..) 3031067 8 For example we choose to insert a lacquered glass of less than 3mm as the product Planilaque Evolution or Decolac of the applicant company laminated by the first insert interlayer (transparent or even opaque as a precaution) and a second lamination interlayer (transparent or even opaque as a precaution).

Preferably the opaque masking means and in particular the opaque element completely covers the surface of the laminated glazing by simplicity and for optimum efficiency. In one embodiment of the invention (alternatively even cumulative in the first mode), in the configuration i), the masking means comprise (better consist of) the first laminating interlayer (which is chosen opaque, very absorbent or very reflective), preferably in contact with the first reflecting layer and in contact with the second reflecting layer or alternatively comprise a second opaque lamination interlayer between the first transparent lamination interlayer and the bonding face.

This first lamination interlayer (or the second) preferably covers (substantially) the entire lamination surface for simplicity and for optimum efficiency. In particular in this second mode, the first reflecting layer preferably comprises a stack of thin layers comprising a possible thin sublayer, in particular a dielectric layer, for example an oxide and / or a metal or silicon nitride, a metallic thin layer (optionally nitride) and a thin overcoat, especially dielectric, for example an oxide and / or a metal nitride or silicon, said RL being at least 20% and even at least 50% or 60% and better with said TL not more than 10% and not more than 5%.

And preferably the second reflecting layer (identical or similar to the first reflecting layer) comprises a stack of thin layers comprising a possible thin underlayer, especially dielectric, for example an oxide and / or a metal or silicon nitride, a layer thin metal (optionally nitrided) and a thin overcoat, especially dielectric, for example an oxide and / or a metal nitride or silicon, said RL being at least 20% and even at least 50% or 60% % and even better with said TL of at most 10% and even at most 5%. Preferably, for the first and / or second reflective layer, the thin metal layer (or the thin metallic layers) is deposited by physical vapor deposition, in particular by magnetron sputtering. Advantageously, the metal thin layer is chosen from a layer of aluminum, zinc, chromium, tin, nickel, niobium (in particular niobium nitride), or preferably stainless steel, or else silver or copper, for example metallic thin layer deposited by physical vapor deposition, in particular by magnetron sputtering or by evaporation. In the present invention, the term "thin layer" is intended to mean a monolayer 5 of submicron thickness, preferably of thickness less than 300 nm, or even at 150 nm and better still less than or equal to 100 nm. Above the thin metallic layer (away from the front face) can be arranged (directly) a preferably mineral overcoat, especially dielectric, for example an oxide and / or a nitride and preferably a layer thin, for example deposited by physical vapor deposition, in particular by magnetron sputtering and even more preferably by the same deposition technique as the thin metal layer. The first and / or second reflecting layer may in particular be a stack of thin layers: preferably inorganic, and / or preferably the number of thin layers is less than 5, or even less than or equal to 4 or even 3, and / or preferably with a total thickness of less than 300 nm, or even 200 nm and better still less than or equal to 150 nm. 20 - hardenable stack (after deposition of the stack, heat treatment and preferably quenching). The first and / or second reflective layer may in particular be a stack of thin layers comprising in this order (away from the front face): a possible thin layer, in particular a dielectric layer, for example an oxide and / or a nitride, - (directly) the thin metal layer - and a thin overcoat, especially dielectric, for example an oxide and / or nitride, (directly) on the thin metal layer.

The overlayer (mono or multilayer) and the possible underlayer (mono or multilayer) serve in particular to adjust the color, improve durability and transformability. In one embodiment, the first and / or second reflective layer is a thin film stack comprising a thin silica underlayer, a thin metal layer of chromium, in particular with a thickness greater than 8 nm, and a nitride overlay. silica and optionally another optionally titanium-based topcoat optionally oxidized, especially of thickness less than 5 nm. This latter layer is used for mechanical durability and hardenability. The first and / or second reflective layer using chromium is not altered by a moist atmosphere, for example a body of water, unlike silvering which requires the addition of opaque anti-corrosion paint. The first and / or second reflective layer using chromium also has scratch resistance comparable to pyrolized layers, and is resistant to cleaning and disinfection. The first and / or second reflective layer using chromium is heat-treatable (i.e., heat-toughenable). The thermal quenching can be performed on the first glass sheet before depositing this layer on the front face. The thermal quenching may also be performed on the first glazing already coated with the front face chromium layer (and optionally with an adjacent glass frit base layer) or with another quenchable metal thin layer. The first and / or second reflective layer using chromium can be obtained by magnetron sputtering. The metal layer stack chrome for example may be that used in the MIRASTAR® product sold by the company SAINT-GOBAIN GLASS.

The first and / or second reflective layer using chromium is not necessarily completely opaque. The reflective layer using chromium typically has a light reflection of the order of 60% and a light transmission of the order of 3%. In one embodiment, the first and / or second reflective layer 25 is a stack of thin layers comprising in this order (away from the front face): a thin underlayer selected from a layer of silicon nitride , titanium oxide (TiO2), tin oxide (5nO2), mixed zinc oxide and tin (SnZnOx), silicon nitride and zirconium (SiZrNx), in particular 30 thick preferably, less than 150 nm, a thin metal layer of niobium, or niobium nitride, in particular with a thickness of at least 20 nm and preferably less than 100 nm, a thin overcoat, in particular with a thickness of at least 20 nm and preferably less than 100 nm, selected from a layer of silicon nitride, titanium oxide, tin oxide, mixed oxide of zinc and tin, silicon nitride and zirconium. Preferably the underlayer and the overlayer are identical.

Moreover, the first and / or second reflective layer, in particular deposited on the front face and / or the diffusing means in layer (s), in particular deposited on the front face, may preferably be essentially mineral, just like the first glass sheet.

Thus, preferably, the front face of the first glass sheet may be coated with the first and / or second reflective layer and the first glazing may be thermally tempered with the reflective layer, in particular with a mineral overcoat, in particular dielectric, for example an oxide and / or a nitride and preferably thin and optionally with one or more layers, preferably mineral (s), in particular enamel or glass frit, forming the diffusing means, on the first glazing and / or optionally a decorative layer, preferably essentially mineral, in particular enamel or glass frit, on the rear face. In one embodiment, the first and / or second reflecting layer 15 is a stack of thin layers comprising a thin metal layer of stainless steel, in particular with a thickness greater than or equal to 5 nm and less than 50 nm or even 20 nm, and a thin overcoat of titanium nitride in particular with a thickness greater than or equal to 5 nm and less than 150 nm, preferably between 20 and 30 nm, including these values.

The first extraction pattern or patterns are preferably identical to the second pattern (s) of extraction in the case of an access door. And the first and second light sources are preferably on the same side of the laminated glazing, in particular housed in a frame for attachment to a gantry. The aforementioned opaque masking means according to the invention can be black or gray (dark) or even white. Preferably opaque for the first opaque layer: - a transmission factor (at the main wavelengths of Cl and / or C2 and / or C3 and / or C4, and even in all the visible) of at most 2% and even not more than 1% or 0.5% (including a TL of not more than 2% and not more than 1% or not more than 0.5% or not more than 0%, 05%) - and / or absorption (at the main wavelengths of Cl and / or C2 and / or C3 and / or C4), and even throughout the visible range) of at least 80% and even at less 90%. Preferably opaque for the first opaque layer is understood to mean an optical density of at least 2 and more preferably at least 2.5 and even more preferably 2.8 to 4.5 and in particular 3 to 4 Opaque for the second opaque layer is preferably meant: a transmission factor (at the main wavelengths of C3 and / or C4 and / or C1 and / or C4 and even in all the visible range); 'not more than 2% and not more than 1% or not more than 0,5% (including a TL of not more than 2% and not more than 1% or not more than 0,5% or of not more than 0.05%) 5 - and / or absorption (at the main wavelengths of C3 and / or C4 and / or C1 and / or C4 and even throughout the visible) of at least 80 % and even at least 90%, or opaque for the opaque second layer is preferably an optical density of at least 2 and more preferably at least 2.5 and even 3 more preferably 2.8 to 4.5 and in particular from 3 to 4. Preferably, opaque is understood to mean opaque element, in particular the first (or second) lamination interlayer (or an additional polymeric film): a transmission factor (at the main wavelengths of C1 and / or C2 and / or C3 and / or C4) , and even in all visible areas) of not more than 2% and even 1% or 0.5% (including a TL of not more than 2% and not more than 1% or not more than 0.5% and preferably an absorption (at the main wavelengths of Cl and / or C2 and / or C3 and / or C4), and even in all the visible range) of at least 80% and even at least 80%. 90%, or a RL of at least 50%. Preferably the first (or second) lamination interlayer (or an additional polymeric film) forming or forming part of the masking means has a TL of at most 10%. better not more than 2% and not more than 1% or not more than 0,5% and not more than 0,1% or zero.

As a first interlayer for lamination, it is possible to choose in particular a sheet (one or more sheets) of thermoplastic material made of ethylene vinyl acetate (EVA) or else of polyurethane (PU) or polyvinyl butyral (PVB). Such a thermally crosslinkable (epoxy, PU) or ultraviolet (epoxy, acrylic resin) multi-component or single-component resin sheet is preferred.

The first lamination interlayer is for example submillimetric, in one or more sheets at the assembly. The first interlayer for lamination is preferably chosen from EVA and PVB. EVA has the advantage of adhering well to the usual protective paints of silver mirrors. The protective paint may be monolayer or mutilayer. In silver silver mirrors, a tin treatment is often carried out after silvering, in order to promote the adhesion of the upper layers and to improve the resistance to the corrosion of silver. One or more layers of protection, for example based on paints, are then deposited on the silver layer. For example, patent application FR2936340 describes a mirror comprising a protective coating combining two successive layers of paints of different types. These paints can be organic type or inorganic type, solvent or aqueous. Typically, the total thickness of this protective paint (in multilayer here) once dry is about 50pm.

If the first laminating interlayer is a PVB preferably, in the case of a silver-silvered layer, the protective paint may be a lacquer. In order to optimize the adhesion between the lacquer layer and the polymer interlayer, the lacquer layer is preferably subjected to the action of a plasma, in particular by a treatment of the corona discharge type, before heat treatment. For the same purpose, it is also possible to deposit on the lacquer layer silanes, for example by spraying or scouring. These treatments make it possible to use lacquers whose adhesion with the polymer interlayer sheets is naturally weak. They nevertheless generate an additional cost and are therefore not preferred. As an example of a preferred lacquer, those described in the examples of the application WO2009 / 081077 can be used. In the case of first (respectively second) reflecting layer in the form of a stack of thin layers, EVA or PVB can be used interchangeably. As an example of opaque PVB (white, black) forming or forming part of the masking means mention may be made of the Vanceva Polar White® (Saflex product) of Solutia, mainly absorbent, or Vanceva® Absolute black of Solutia, which is mainly absorbent, or even the Kuraray Trosifol Diamond White®, of Null TL, reflective. As an example of EVA (white, black, etc.) forming or forming part of the masking means, mention may be made of an opal EVA such as Bridgestone's EV038® and Pujol's EVALAM color black® (ref LAEV200CO2). The outer face is diffusing in particular by sandblasting or acidic or receives a diffusing layer including white as an enamel or paint. And / or the outer face is diffusing in particular by sandblasting or acidic or 35 receives a diffusing layer including white as an enamel or paint. The first and / or second extraction means may be permanent or removable, including temporary: sticker, erasable marker.

The first and second light sources are preferably arranged on the same side of the laminated glazing (first and second slices are on the same side, laminated glazing edge) if the slice opposite to the first and second slices is visible. This is the case for a subway access door with two leaves (sets 5 glazed according to the invention) side by side and retractable for the passage of the user. The luminous glazed assembly may comprise, at the periphery of the first wafer and the second wafer, a profile, in particular at least partly metallic, protruding on the outer face preferably over a distance W between 1 cm and 3 cm, enclosing or carrying the first light source and the second light source. The profile can thus be used to hide the vision of hot spots. The profile is not necessarily in optical contact with the outer face. The profile can be: - glued, by glue or double-sided opaque, which will absorb the high-angle rays 15 - or is glued by adhesive or double-sided transparent, the high-angle rays are reflected on the reflector profile and go out further or are absorbed by the opaque (rendered surface) profile. Naturally, the first radiation has a given first spectral range. Of course, the second radiation has a second given spectral range. The first (respectively second) main radiation according to the invention means the most intense radiation in the spectral range emitted at time t0 (respectively t ') by the first light source. And third (fourth) principal radiation according to the invention is understood to mean the most intense radiation in the spectral range emitted at time t0 (respectively t ') by the second light source. Preferably the spectral range of the first radiation is narrow at most 50 nm and is non-overlapping with the spectral range of the second equally narrow radiation or with an overlap of less than 50 nm for normalized intensities of less than 0.15, for example overlap between red and amber or between green and blue. Preferably, the signaling colors commonly used today are searched. Thus: at t 0: the first source emits in the green with X1 in a range from 515nm to 535 nm and preferably at a mid-height spectral width of less than 50nm (and the extracted light Cl is green defined by a first main extracted radiation at X1 'substantially equal to X1, for example 3031067 distinct of at most 10nm or 5nm and preferably with a spectral width at mid-height of less than 30nm), the second source emits in the red with X3 in a range from 615nm to 635nm and preferably from a spectral width at mid-height of less than 30nm (and the extracted light C3 is red defined by a third main extracted radiation at X3 'substantially equal to X3, for example distinct from 10nm or 5nm and preferably with a mid-height spectral width of less than 30nm) or white and the first source emits in red with X2 in a range of 615nm to 635nm and spec width preference at half the height of less than 30 nm (and the extracted light C2 is red defined by a second main extracted radiation at X1 'substantially equal to X1, for example distinct from at most 10 nm or 5 nm and preferably with a spectral width at mid-height of less than 30 nm) and preferably the second source emits in the green with X4 in a range from 515nm to 535nm and preferably of spectral width at mid-height of less than 50nm (and the extracted light C4 is green defined by a fourth main extracted radiation at X4 'substantially equal to X4, for example distinct from at most 10nm or 5nm and preferably with a spectral width at mid-height of less than 30nm) or alternatively the first continuous source of emit in the red with X4 in a range from 615nm to 635nm and preferably spectral width at mid-height of less than 30nm (and the extracted light C4 is red defined by a fourth main extracted radiation) ipal at X4 'substantially equal to 25 X1, for example distinct from at most 10nm or 5nm and preferably with a spectral width at mid-height of less than 30nm). Another configuration is that for example at t3 each source emits in green or in white. It is also possible for one of the sources to be off (hence the following configurations: red and off state, green and off state, white and off state). There may be distinctly colored decorative areas. Advantageously, the first light source is a set of light-emitting diodes-preferably aligned-on a printed circuit board called the first PCB support (preferably a strip) and coupled to the first slice, and the second light source is a set of light-emitting diodes - preferably aligned - on a PCB said second PCB support and coupled to the second slice which is preferably aligned (or even shifted) of the first 3031067 slice or aligned or even shifted from the opposite slice to the first slice. The first and second PCB supports are spaced, joined or in a common PCB support (first and second slices on the same side), for example glued with a thermal glue to a metal profile. The first (second) PCB support or the common support may be a resin composite (epoxy) reinforced with glass fiber (often called FR-4), metal (aluminum, copper, etc.). It is preferably millimeter thick (less than 10 mm preferably) or even at most 1 mm.

Of course, the glazed unit can also operate in static mode, that is to say only propose the combination Cl and C3 (or C1 and C2 off state, or C3 and C4 off state, if any). In this case, the first light source may even contain only first diodes X1 and the second light source contain only third diodes X3.

At the first source there is a first diode which emits in the green with X1 in a range of 515nm to 535nm, and at the first source has a second diode which emits in the red with X2 in a range of 615nm. at 635nm. The response of the ear is better for green than for red and furthermore the glass (mineral or organic) absorbs more red than green. We can perceive a red too pale. Also, preferably, the electrical circuit of the first diode is adjusted (resistor (s) adapted (s) etc.) so that the flow F1 (or power) emitted by the first diode is less than 0.8, even less than equal to 0.7 or 0.6 times the flux F2 (or power) emitted by the second diode. Preferably, it is the same for the second light source emitting in the red at tO then in the green at t '. In order to have a flux Fl lower than that of F2, it is possible to adjust the luminous intensity of the red diode to be greater than that of the green diode and / or to have on the first PCB support a number of red diodes per unit of PCB support length greater than the number of green diodes per unit length of PCB support. Preferably, it is the same for the second light source emitting in the red at tO then in the green at t '. For example, one can have on the first PCB support (respectively the second) n times the following sequence, n integer greater than or equal to 1: two red diodes / one green diode ... In the case of a common PCB support one can have: 3031067 17 - for the first set of diodes n times the following sequence, n integer greater than or equal to 1: two red diodes / one green diode ... - for the second set of diodes n 'times the following sequence , n 'integer greater than or equal to 1, preferably equal to n: two red diodes 5 / a green diode ...

It can be spaced from the ground (without a low post and / or high horizontal) and fixed laterally to a bearing (block fixed or placed on the ground). The ground is the firm ground or ground of a part of a vehicle (boat , train etc). The door can also be in a frame attached to an adjacent masonry. Classical luminous landmarks (green arrow, red cross ...) can be kept or removed in the racks. The first and second extraction surfaces are more easily identifiable especially for characters with reduced vision. The invention applies more widely to form signaling and / or light decorations (or even functional lighting) of distinct colors at a given moment on two distinct sides of the glass unit, each signage or decor being switchable. independently preferably automatically or manually by the user (ambient light etc.). The luminous glazed unit according to the invention can be between a first accessible space (with a pedestrian or vehicle traffic) and second accessible space (with a pedestrian or vehicle traffic). More broadly, the luminous glazed unit according to the invention can be a partition, especially between two zones of a building or of a land, sea or air vehicle or between two outer zones, a railing, a step or even a floor slab upstairs (eg light path to go to 3031067 32 emergency exit) or a closet door (cabinet), bathroom furniture, a totem. The mounting profile of the luminous glazed assembly according to the invention (or attachment of the first source and / or the second source) may be a U or E 5 with the central branch of the E spaced apart from the laminated assembly less than 1 mm or even extending in a groove between the first and second glazings. Naturally, there may be on the first glazing a plurality of extraction patterns, in particular in horizontal or vertical strips, preferably spaced at least 2 cm, 5 cm, even at least 10 cm.

Naturally, there may be on the second glazing a plurality of second extraction patterns, in horizontal or vertical strips spaced at least 2 cm, 5 cm, even at least 10 cm. The details and advantageous features of the invention will now be apparent from the following nonlimiting examples, with the aid of the figures: FIG. 1 shows access portals with double one-way signaling in a metro station - the figures following 1 a and 1b show another example of light areas on each side of a leaf and the arrangement of the first and second light sources. FIGS. 2, 2 ', 3, 4, 5, 6 are schematic (sometimes partial) views in section of luminous glazed assemblies in several embodiments of the invention, FIGS. 7a and 7b show another embodiment of the invention. example of bright areas on each side of a glazed assembly in interior application.

The figures are not to scale. EXAMPLES FIG. 1 shows a series of four access portals 1000 in a metro station between the hall 1001 on the ticketing side and the space on the row side 1002 (schematized by rails) each with two independent luminous signals (single vision on the side of the hall / ream side) and in dynamics (by control means of non-described, conventional light sources). The means for reading a ticket or a pass are not shown and are conventional as the means triggering the opening of the leaves 100. Three access gantries each comprise between two carriers 70 for example parallelepiped and metal, two leaves 100 of rectangular type 3031067 33 (length following the vertical, width of less than 450mm preferably) spaced a few cm, the lateral edges 15, 16 here having a radius of curvature away from the bearing 70. The side slices 15, 16 and the wafer 14 opposite the carrier are free, straight, polished or diffusing. The fourth gantry (most right) has a single leaf 100 connected to a single bearing (possibly against an elevator glass wall, a sliding outlet door, etc.). Each leaf 100 comprises a laminated glazing unit comprising a first preferably tempered mineral glazing (flat or curved and of any possible general shape) with a first wafer, main faces called inner face and outer face 12, a first lamination interlayer, a second mineral glazing (planar or curved and of any possible general shape, identical to the first glazing) with a second slice and principal faces called bonding face and outer face 12 '. The first and second slices (in the bearing 70) are on the same side of the laminated glazing slices aligned or shifted by less than 1mm.

At the instant t0, the first and third porticoes each comprise on the right-hand side of the hallway 70 a green signaling arrow s1 oriented towards its leaves 100 and each have a green luminous surface 50 opposite the hall, in a first band here horizontal 50 partially covering the first glazing which include mirror areas 17 outside this light surface via a first reflective layer (mirror) on the inner face. If the ticket or the pass is invalid, the green surfaces 50 can become red and even flash on a short time (less than 10 s) for example 1s to 5s and become green again. The second gantry 100 (starting from the left) has on the right-hand door 70 on the hall 1001 side a red signaling arrow s2 and has a red light surface 50 on the hall side, in a here horizontal strip 50 partially covering the second glazing which have mirror areas 17 via a second reflective layer (mirror) on the bonding face (in the face). On the other side (not visible), at time t0, the first and third gantries each comprise on the left-hand carrier 70 on the 1002 side a red signaling arrow and each have a red luminous surface on the ream side, in one section. horizontal strip 50 'on the second glazing facing or offset vertically from the first horizontal strip, the second glazing comprising mirror areas 17 outside this light surface via a second reflecting layer (mirror) facing the bonding (in the face) .

On the other side, at time t0, the second gantry comprises on the left-hand carrier on the rowing side 1002 a green signaling arrow pointing towards its leaves, each of which has a green luminous surface side reamed in a horizontal strip 3031067 34 on the first glazing facing or offset vertically from the opposite horizontal strip, the first glazing having mirror areas via a reflective layer (mirror) on the internal face (in the face). Each pattern diffusing on the outer face and the outer face, in particular with respect to the reflecting layers, makes it possible to extract red or green light on the outer or outer side resulting from radiation emitted by the first and second light sources and guided (the two a plurality of diodes per leaf or optical fibers extracting) hidden light sources in the carriers 70, the first light source in optical coupling with the first wafer, the second light source 10 in optical coupling with the second wafer. The illuminated surfaces can be of any shape and extent for signage and / or decor. A luminous surface may comprise a fine pattern such as an arrow or be closed and hollow (geometric outline, etc.).

The following figures 1a, 1b show another example of light zones on the leaves and the arrangement of the first and second light sources in the case of the access gantry. Figure la shows a front view of a leaf 100a hall side and Figure lb 20 shows in front view this railed side wing. Hall side, there are first luminous areas in three horizontal and rectangular bands namely high band 50a, central band 50b and low band 50c, spaced by square or rectangular mirror 17 (full mirror layer laminated side) for example 10 cm height (here width). Rows 25 are also visible second luminous areas in three horizontal bands 50'a, 50'b, 50'c and rectangular for example congruent (same size and same shape) to the first light areas spaced by mirror strips 17 '(full mirror layer laminating side) for example 10 cm high (here width). The first vertical high band 50a has on the outer face: a first network of spot diffusing patterns 5, patterns of width of at most 5 mm and spaced apart by a pitch p1 of at most 5 mm, with a first pattern 5 a remote W of the first wafer (VV about 3cm for example) as for the other two bands - a first set of characters 5b diffusing such as a LOGO, each 35 width 13 at most 5 cm spaced a step p3 of at most 1 cm surrounded by the first pattern of scattered scatter patterns 5 - a first decorative scattering pattern 5c (two concentric circles) of width (and even outer diameter here) 12 cm and not more than 5 cm surrounded by the first network of point scattering patterns.

The discrete patterns are for example geometric, like disks (or squares rectangles etc). The first low band 50c has on the outer face a flat white enamel. The second low band 50 'c is congruent with the first low band 30 and has a flat white enamel: As in Figure 1, the leaf 100a is a laminated glazing. The first glazing is on the hall side, an array of diodes 4 on a PCB support 41 in the form of a strip is optically coupled to the first wafer. At t0 the diodes 4 emit in green and t 'in red (or white or other color, blue for any other application). The second glazing is reamed, a 4 'diode alignment on a PCB support 41' in the form of a bar is optically coupled to the second wafer. At t0 the diodes 4 'emit in the red and at t' in the green (or the white or other color, blue for any other application). FIG. 2 shows in greater detail a partial sectional view of a glazed unit 200 with a double one-way light zone in a second embodiment comprising a laminated glazing unit comprising: a first glazing unit 1, here of rectangular shape (by example length of 780mm depending on the vertical, width for example 250mm), plan or alternatively curved (tempered), clear silicosodocalcic glass or extraclair 10 hardened (for example about 6mm including the glass called Planilux of the Applicant, hardened or still the Diamond glass of the Applicant), of refractive index n1 of about 1.52 to 550nm, TL of at least 90%, with a first main face 11 called internal face, a second main face 12 called face external, a first slice 15 13 which is vertical in mounted position, - a first lamination interlayer 6 in thermoplastic material here transparent preferably EVA, for example submillimetric, in a sheet d e 0.38mm, transparent even clear, or alternatively tinted (or opaque) 20 - a second glazing 1 ', mineral glass, identical to the first glazing, with a main face of gluing 11' lamination intermediate side 6, one side so-called outer opposite 12 ', a second wafer 13', of refractive index n2 of about 1.52 to 550nm, of TL of at least 90%. The glazed assembly 200 further comprises: a first light source 4, here a first set of red and green light-emitting diodes 4 aligned on a printed circuit board, said common PCB support 410, source optically coupled to the first wafer 13 the first glazing 1 guiding the light emitted by the diodes preferably spaced apart by at most 1 mm from the first wafer 13, preferably centered on the first wafer and having a width less than the thickness of the first wafer 1, for example each diode with a width WO of 4mm or less, - first light extraction means 5, on the outer face 12, having a first extraction pattern (or a plurality of first extraction patterns) defining a first surface 50, partially covering the outer face, the extracted light being visible on the outer side, first extraction means such that the extracted light 30 tO is one e first color called Cl and preferably said t 'is a second color called C2 distinct from C1, - inner side face 11, a first reflecting layer 2, extending over the entire internal face, in particular opposite the first extraction surface 5, the first glazing 1 with the first reflecting layer 2 having a first light reflection RL, measured on the side of the outer face 12, of at least 20% and even at least 60% and preferably a first light transmission TL less than or equal to 3% or even 1% measured on the side of the inner face 11 10 - a second light source 4 ', optically coupled to the second glazing by the second wafer 13', second glazing thus guiding the light emitted by the second light source, second source of light controlled statically or dynamically, to emit t0 said third main radiation at a wavelength called X3 distinct from 15 Xi and pr substantially equal to X2 and preferably, to emit at said instant t 'a fourth main radiation at a wavelength called X4, preferably separate from X3, - second light extraction means 5' on the outer face 12 ', having a second extraction pattern (or a plurality of second extraction patterns) defining a second extraction surface 50' partially covering the outer face, the extracted light being visible on the outer side, second means of extraction of light such that the light thus extracted at t0 is of a color called C3 distinct from Cl, and preferably said t 'is of a color called C4 distinct from C2, the second extraction pattern being here opposite of the first extraction pattern, - bonding side side, a second reflecting layer 2 ', extending over the entire bonding face 11' in particular opposite the second extraction surface 50 ', the two 1 'glazing 1' with the second reflecting layer 2 'has a second light reflection, measured on the side of the outer face 11', of at least 20% and even at least 60% and a second light transmission TL lower or equal to 3% or even 1% measured on the side of the bonding face 11 ', the first extraction surface 50 also being opposite the second reflecting layer.

More specifically, the first reflective layer 2 comprises a first layer of silver, a silvering layer for forming a mirror, preferably at least 40 nm and even at least 60 nm and even less than 90 nm (and better than 120 nm), in particular around 100 nm, and said first RL being at least 60% and even at least 85% or 90% and first TL being at most 1 % and even at most 0.5%. The first reflective layer 2 is coated with a protective paint 3 forming a first opaque masking layer. The second reflective layer 2 comprises a silver layer 2 ', a silvering layer for forming a mirror, preferably at least 40 nm and even at least 60 nm and even at least 90 nm. (and better still at most 120 nm) especially around 100 nm and said second RL being at least 90% and second TL being at most 1% and even at most 0.5% or 0.05% . The second reflective layer 2 'is coated with a protective paint forming a second opaque masking layer 3'. These masking layers 3, 3 'are in fact anti-radiation mixing means of the first and second sources extracted at the level of the first extraction surface 50 and at the level of the second extraction surface 50', avoiding an interaction. of rays or even a guide (before extraction) of rays between first and second reflecting surfaces, especially between offset extraction surfaces. Regarding the manufacture, the first (respectively second) glazing coated full face silvering with its protective paint. The first and second light extraction means 50, 50 'are one or more sandblasted areas (or etched by acid etching) respectively of the face 12 and the face 12'. As alternative extraction means, there may be mentioned a diffusing layer such as a white enamel, in particular with the majority of TiO.sub.2 as the pigment. The thickness is typically between 40 and 60pm, or a white paint. A paint formulation may be deposited according to the curtain process. The solvent is xylene or alternatively aqueous. The lacquer after drying comprises, for example, the following ingredients: a binder in the form of a polyurethane resin obtained by crosslinking, with a non-aromatic isocyanate, of hydroxylated acrylic resins resulting from the polymerization of an acrylic styrene; mineral materials (pigments and loads) up to 55% by mass. As alternative (or cumulative) extraction means, mention may be made of a paint, stickers or suitable erasable ink. The first source 4 (each diode) is of extension (width of the emitting face) WO less than the thickness of the first glazing 1 typically WO of at most 5 mm and the first source (each diode) substantially centered with respect to the first slice 13. The distance d1 to the first slice 13 of the first source 39 (each diode) is from 1 to 5 mm better from 1 to 3 mm. The second source (each diode) is of extension (width of the emitting face) VV'0 less than the thickness of the second glazing 1 'typically VV'0 of at most 5mm and the second source (each diode) substantially centered compared to the second tranche. The distance from l to the second slice 13 'of the first source 4 (each diode) is from 1 to 5 mm better from 1 to 3 mm. The first light source 4 is dynamically controlled to emit at time t0 via a first series of first diodes 4 a first main radiation at a first wavelength called X1 and at time t4t0 via a second series of first diodes 4 'a second main radiation at a second wavelength called X2 distinct from X1. The second light source 4 'is dynamically driven to emit at time t0 via a third series of second diodes 4' a third main radiation at a third wavelength X3 distinct from X1 and at time t4t0 via A fourth series of second diodes 4 'a fourth main radiation at a fourth wavelength X4 distinct from Xl. At t0: - the first series emits in the green with X1 in a range from 515nm to 535nm and spectral width at mid-height of less than 50nm (and the extracted light Cl is green defined by a first main extracted radiation at X1 'substantially equal to X1, distinct by at most 10nm or 5nm and with a spectral width at mid-height of less than 30nm), - the third series emits in the red with X3 in a range from 615nm to 635nm and from spectral width at mid-height of less than 30 nm (and the extracted light C3 is red defined by a third main extracted radiation at X3 'substantially equal to X3, distinct from at most 10 nm or 5 nm and with a spectral width at half height less than 30nm) or white. At t: 30 - the second series emits in the red with X2 in a range from 615nm to 635nm and spectral width at mid-height of less than 30nm (and the extracted light C2 is red defined by a second principal extracted radiation at X1 'substantially equal to X1, distinct by at most 10nm or 5nm and with a spectral width at mid-height of less than 30nm); and the fourth series emits in green with X4 in a range from 515nm to 535nm and with a spectral width at mid-height of less than 50 nm (and the extracted light C4 is green defined by a fourth main extracted radiation at X4 'substantially equal to X4, distinct by at most 10 nm or 5 nm and with a spectral width at half height less than 30nm). Alternatively, the first source continues to emit in the red with X4 in a range from 615nm to 635nm and spectral width at mid-height of less than 30nm (and light extracted C4 is red defined by a fourth main extracted radiation) at X4 'substantially equal to X1, for example distinct from at most 10nm or 5nm and preferably with a spectral width at mid-height of less than 30nm).

Another configuration is that for example at t3 each source 4, 4 'emits in green or in white. It is also possible for one of the sources to be off (hence the following configurations: red and off state, green and off state, white and off state). The PCB support is in a bar, rectangular not exceeding the edge of the glass unit (of width less than or equal to the thickness of the slice of the glass unit and of length less than or equal to the length of the slice of the glass unit). Each set of diodes 4, 4 'alternately comprises LEDs "red" and "green". The maximum spacing between the diodes of the same color is chosen at most 20mm. The diodes of the first source (respectively the second source) each have a given main direction of emission substantially parallel to the first portion (respectively to the second portion), for example less than 5 °. Normal Luminance of a pattern 5, 5 'measured on the outer side 12 or the outer side 12' with green or red light is about 100 cd / m2 (+/- 10 cd / m2). Luminance at normal is uniform at (+/- 10 cd / m2).

The electrical circuit of each "green" diode emitting in the green is adjusted so that the flux F1 emitted by this "green" diode is less than 0.8 even at 0.5 times the flux F2 emitted by a "red" diode. emitting in the red. For example, for each set of diodes on the common PCB support, it is possible to have repetitions of the following sequence: two red diodes / one green diode 30 ... The PCB support 410 is in the interior volume - divided into two chambers 74 , 74'- a mounting section 7 section U, preferably metal (aluminum, lacquered steel) or plastic variant (PVC etc) or wood comprising: 35 - a base 72 facing the edge of the glazed assembly 200 (including the first and second wafers 13, 13 ', the central wafer with the first laminating interlayer 6), the metal base here carrying the support PCB 410 and serving for example as a heat sink, else of the base 72 of the first and second wings 71, 73 respectively extending on outer face 12 and outer face 12 'for example over a width W of 3cm. The common PCB support is bonded by a thermal glue 18 to the metal base 72 of the U-shaped section 7. The face 12 'is a free surface of the luminous pane, is visible or even accessible (to the touch). The face 12 is a free surface of the luminous glazing, is visible or even accessible (to the touch). The glazed assembly 200 could be assembled in an insulating glass or vacuum if really necessary (double glazing or triple glazing). The first and second slices 13, 13 'are straight, polished. Opposite slices are straight, polished or even diffusing. The side and opposite edges 15 may be coated with an opaque paint so as not to ignite. It is also possible to place a polymeric seal on these opposing edges, for example for greater comfort if the leaves fold too quickly on the pedestrian or to hide the light. Other diodes may be added to the opposite wafer (not shown here), particularly in the case of glazing with a large first extraction surface and / or with several spaced centimetric units. We can then place a metal frame or polymeric seal housing these other diodes on this opposite edge. The 4,4 'diodes are top emission ("top emitting" in English) The 4,4' diodes are conventional without collimation optics - and even without (pre) encapsulation - having an emission diagram with large angles for example lambertian emission (for example with angle at mid-height of 120 °). As diodes it is thus possible to choose the NSSM124T sold by the company NICHIA width 3mm centered on the coupling portion 13, 13 '. It is preferable to avoid any color mixing due to lateral leakage of light from the first diodes 4 of the internal volume 74 to the second glazing 1 '(radii not coupled to the first glazing 1), in particular refraction in the first spacer 6 and or especially in the second slice 13 ', and / or lateral leakage of light from the second diodes 4' of the internal volume 74 'to the first glazing unit 1 (radii not coupled to the second glazing unit 1), in particular refraction in the first intermediate 6 and / or especially in the first portion 13.

Also, a reflective piece 75 of aluminum is fixed on the common PCB support 410 by an adhesive 18 '(or a notch) against the central slice 13' of the laminated glazing to partition the light of each source 4, 4 'and the reflect. This part is preferably of thickness less than or equal to the thickness between inner face 5 and bonding face (central slice 13 "), for example less than 0.8 mm and even 0.5 mm. less than 1mm on the first and second slices 13, 13 'Between the piece 75 and the central slice there is preferably no glue or any other means of attachment.

In a variant not shown, the support 7 is a section section E rather than a U with a central branch 75 of the E metal partitioning and reflecting the light of the first light source and the second light source, by example against or spaced less than 1mm from the central slice of the laminated glazing. The profile and this central branch 75 is of thickness less than or equal to the thickness between the inner face and the bonding face, for example less than 0.8 mm and even 0.5 mm. In this case each first and second source is on a separate PCB fixed on the base of the profile. In a variant not shown, the assembly can be performed using a PVB interlayer film or SentryGlas® DuPont particular by activating the surfaces of the protective paints using an adhesion promoter. Figure 2 'shows a partial sectional view of a luminous glazed assembly 200' in a variant of the second embodiment. Only the differences from the second mode are described.

The luminous glazed unit 200 'differs as follows from the glazed unit 200. The sources (diodes) 4' and 4 'are side-emitting, each with separate PCB support 41, 41' either side-by-side (fixed to each other). the other) by their rear face against or as here fixed by an adhesive 18 for example conductive on a piece (metal) 75 spacer glued to the frame 7 by glue 18 for example conductive and against the central portion 13 ". The PCB supports may participate or be sufficient to partition the lights of different colors (at t0, t0 'etc.) if they are opaque by nature, including reflectors and of sufficient width (in particular abutting against their edge 13 or 13' of the laminated glazing and the base 72) Alternatively, the PCB supports are attached to the side portions 71, 73 of the frame.

Figure 3 shows a partial sectional view of a luminous glazed assembly 300 in a third embodiment. Only the differences from the second mode are described. The luminous glazed unit 300 differs as follows from the glazed assembly 200.

The first source 4 (each diode) has collimation means 42 to reduce the emission angle sufficiently to avoid (or limit) any lateral leakage to the second glazing 1 '. The second source 4 '(each diode) comprises collimation means 42' in order to reduce the emission angle sufficiently to avoid (or limit) any lateral leak towards the first glazing 1. For example, we go from an angle at mid-height of 120 ° to 60 °. The common PCB support 210 remains attached to the base 7. Fig. 4 shows a partial sectional view of a light glazed unit 400 in a fourth embodiment. Only the differences from the second mode are described. The luminous glazed assembly 400 differs as follows from the glazed assembly 200. First and second PCB supports 41, 41 'are on a common metal (aluminum) section 76, for example a strip of width less than or equal to 20 mm. thickness of the slice of the glazed assembly, section T with a protruding portion 75 to partition the light sources 4,4 'and reflect the troublesome rays. Here, this profile 76 is not fixed on the mounting profile 7 of the glass unit for example to a bearing. Each of the diodes of the first source 4 (respectively of the second source 4 ') has a primary encapsulation 44, 44' and is glued to the first wafer 13 (respectively to the second wafer 13 ') by a transparent double-sided adhesive 45 , 45 'as a polyester support with double-sided acrylic glue as the product D9605 called the company NITTO for example not exceeding the edge of the glass assembly, outward.

It is also possible to eliminate the common section 76 and to have a profile (type of bar of rectangular section or even of U, in L) thus glued for each source 4,4 '. Two profiles U or L may be spaced or contiguous or fixed between them and thus keep the partitioning. One can even have on sides of the opposite side of the glass unit two sections thus glued (sources on two opposite sides).

Fig. 5 shows a sectional view of a luminous glazed assembly 500 in a fifth embodiment.

3031067 44 Only the differences from the second mode are described. The luminous glazed assembly 500 differs as follows from the glazed assembly 200. The first and second reflective layers 2, 2 'are no longer silvered mirrors with their protective paints but stacks of 5 thin layers 2, 2'. The first lamination interlayer -6 'is an opaque PVB or EVA (highly reflective or highly absorbent, TL as low as possible), for example white or black, forming anti-mixing means radiation of the first and second sources extracted at the level. of the first extraction surface 50 and at the second extraction surface 50 '(avoiding ray guidance between first and second reflective surfaces). Furthermore, the two light sources 4a, 4'a are reproduced, the common partitioning 75 '(facing the central slice 13 "a) all housed in a section 7a on the opposite edges 13a, 13'a to the first and second slices 13,13 'Another first extraction surface 50a adjacent to the first extraction surface 50 and other second extraction surface 50'a adjacent to the second extraction surface 50' is added. the first and second reflective layers 2, 2 ', here a chromium-based multilayer is chosen, such as the SGG MIRASTAR® product from SAINT GOBAIN GLASS, each reflective layer 2, 2' is deposited by magnetron sputtering. This is a stack of thin layers comprising: a thin silica underlayer, approximately 30 nm thick, a thin chromium metal layer, approximately 19 nm thick, an overlayer of silica nitride, about 5 nm thick r, and another overcoat based on oxidized titanium, about 1 nm. The SGG MIRASTAR® product has a TL of 3% and a RL of 60%.

Alternatively, the stack of thin layers of each reflecting layer 2, 2 'is for example the stackable stack according to: - a thin sublayer of silicon nitride, - a thin metal layer based on niobium, or nitride of niobium, - a thin overcoat of silicon nitride.

For example, the layers of SAINT GOBAIN GLASS products ST108 or ST120 or STB120 are selected, described in Tables 1 and 2 below.

For example, the layers of products SS108, SS114 and SS120 from SAINT GOBAIN GLASS described in Table 3 below are chosen.

Alternatively, silver coating layers are left with their protective layers. Naturally, the glazed assembly as described in the various embodiments mentioned above can also operate in static mode, that is to say only 30 offer the combination Cl and C3 (or Cl and off state, or C3 and off state). . In this case, the first light source may even contain only first diodes X1 and the second light source contain only third diodes X3. The glass unit may also be suitable as a light partition (between two zones of a building or a land, sea or air vehicle or between two outer zones), floor slab, step, railing, closet door, furniture of bathroom. Figure 6 shows a sectional view of a light glazed assembly 600 in a sixth embodiment. Only the differences from the second mode are described. The luminous glazed assembly 600 differs as follows from the glazed assembly 200. The reflective layers with their protections are replaced by a reflector film 23 of the largest possible RL, TL as low as possible (and better the least absorbent possible ). This reflective film is between two transparent laminating interlayer sheets 6 (clear, even extraclear) made of EVA or PVB. It may be a metallic film or a metallized polymeric film. The film can be in direct contact without gluing before the lamination cycle. If this film has one or more surfaces coated with glue (pre-glued to one or several interlayer sheets before the lamination cycle), it is preferred that the glue be as transparent as possible. Figures 7a and 7b show another example of light areas on each side of a glazed assembly 700 and in an interior application (in a building etc).

It is a totem (carried by a horizontal low upright 70, for example aluminum, U-section or E to form the common partitioning, housing the two sets of diodes for the two windows. the men's department and the women department in a clothing store or a department store (on land in a shopping area in a maritime vehicle, railway, etc.).

If necessary we can add diodes (for the two windows) housed in a high horizontal amount or the diodes (for both windows) can be alternately in the vertical amount of left and / or vertical right. The amount can be a frame, for example aluminum, and section U or E to form the partitioning preferably common (if diodes on the same side), we can add diodes as needed.

Figure 7a shows in front view the first glazing (outer side side 12) of the glazed assembly 700 on the female spoke side and Figure 7b shows in front view (outer side side 12 ') the male spoke side. On the women's side, we observe in the upper zone (in the mounted position) 5 letters forming the word 'woman' 8a - in the desired language - (or alternatively a drawing or symbol of a woman) for example with a zone of decoration patterns 8b below (here series of diamonds). These patterns 8a, 8b are permanent on the outer face 12, for example textured (sandblasted, frosted, etc.), face opposite to the inner face covered by the first reflective layer, preferably mirror, by silvering with its protective paint. Side ray men, we observe in the high zone (in mounted position) letters forming the word 'man' 8'a - in the desired language- (or alternatively a drawing or symbol of a man) for example with a zone set designs 8'b 15 below (here series of diamonds). These patterns 8'a, 8'b are permanent on the outer surface, for example textured (sandblasted, frosted, etc.), face opposite to the inner face covered by the second reflecting layer, preferably mirror, by a silvering with its protective paint .

The female side patterns are, for example, offset from the male side patterns of D (variable) by at least 1 cm. For example, the patterns 8a and 8'a are shifted. A laminated glazing of architecture similar to that of the laminated glazing unit described in FIG. 2 (by adjusting the positions of the first and second extraction surfaces) or FIGS. 3 to 6 can be produced.

At the instant t0 and even t ', the color of the patterns on the female side may be distinct from that on the men's side. On either side this color can be static or dynamic. Optionally, we can add extraction patterns for promotions (or sales) men's side radius and / or women's radius side. For example, on the women's spoke side, removable extraction means 30 are added, such as stickers or an erasable ink on the outer face 12, for example vertically and peripherally (to keep the mirror function) four symbols 8c to 8f (hat, dress, pants, coat) white or colored (agreeing with the colors of diodes coupled to the first glazing) associated with a percentage of reduction 81 to 84.

For example, on the male spoke side, removable extraction means such as erasable stickers or ink are added to the outer face 12 ', for example vertically and peripherally (to keep the mirror function) four symbols 3031067 48 8'c to 8 'f (tie, shirt, trousers, jacket) white or colored (matching the colors of diodes coupled to the second glazing) associated with a percentage of reduction 81' to 84 '. For a given radius, the symbols and / or the associated percentages are not necessarily of the same color. From one radius to another, the symbols and / or the associated percentages are not necessarily of the same color or illuminated by the same color at a given time t0.
