    "VEHICLE AND E VEHICLE LIGHT GLASS" [0001] The present invention relates to vehicle glazing and especially light glazing for vehicles, especially light-emitting diode glazing and the manufacturing process for such vehicle glazing.
    [0002] An increasing number of vehicles use light-emitting diodes (LED in English or DEL in French).
    [0003] The document WO 2006128941 proposes, for example, a panoramic roof with homogeneous illumination on the surface by light emitting diode (s) (electroluminescent). This roof has a leaf structure that, as shown in Figure 8, is composed of an outer leaf that extracts light, a transparent central leaf that guides light and an internal leaf that diffuses light. The light source consists of a plurality of light-emitting diodes mounted on a side support fixed to the edge of the inner and outer sheets while a hole is made in the central sheet to house the diodes.
    [0004] The panoramic roof is fixed by gluing the peripheral edges of the outer sheet to the roof body. The diodes and the peripheral bonding zone are masked by the internal trim.
    [0005] The invention proposes to expand the range of luminous glazing available for vehicles.
    [0006] The present invention is actually aimed at a luminous vehicle window with an ecological and effective light source (light emitting diodes, optical fiber (s) coupled to diodes, for example), applicable mainly to any ceiling configuration, and especially for ceilings mounted externally on the body roof, roofs that open or are fixed.
    [0007] For this purpose, the luminous vehicle glass must be durable, compact, robust, and at the same time simple, thus corresponding to the specifications imposed by vehicle manufacturers.
    [0008] The present invention also aims at a luminous vehicle glazing that meets industrial requirements (in terms of performance, therefore, cost, pace, automation) thus making it possible to produce
    Petition 870190072528, of 7/29/2019, p. 5/68
    2/29 low cost ”without sacrificing performance.
    [0009] The invention proposes for this purpose a luminous vehicle window comprising:
    - a first sheet of mineral or organic glass with a first main face and a second main face and a margin,
    - a peripheral light source with an emitting face, chosen from an optical fiber and light emitting diodes each comprising a semiconductor microchip on (at least) a profiled support of the diodes (the profiled set and the diodes are usually called a light bar) diodes), with the emitting face facing an edge of the second face said of injection (in contact or not with the second face) for a propagation of the injected visible and / or ultraviolet light called UV in the thickness of the first leaf, representing the first leaf then the guide paper of the injected light (the injection edge being optionally partially excavated in its thickness, optionally even with a recessed part),
    - to form at least one luminous zone:
    - means of extracting the guided light by means of the first and / or the second main face, which are means of surface diffusion of the first and / or the second main face and the means of volume diffusion in the first sheet,
    - and / or when the injected light consists (mainly) of UV, means of converting UV light into visible light by means of the first and / or the second main face, which are luminophores, mainly on the first and / or coming from the second main face (which is then the extraction face),
    - an eventual additional peripheral functional element (therefore distinct from the first sheet), connected to the first sheet (mainly by an internal face and having the element mainly an external free face), which is watertight to the fluid (s), mainly to the liquid water and even steam, (the functional element being, for example, adjacent to the injection edge), mainly a functional element that is selected from an overmoulding or a previously assembled element (metallic or polymeric, chosen, preferably, between one
    Petition 870190072528, of 7/29/2019, p. 6/68
    3/29 encapsulated, an extruded, a joint, mainly glued on the first sheet)
    - a fountain cap, fluid-tight, mainly water in liquid or even steam,
    - the so-called facial cap, that is, it is essentially (or entirely) facing the second face (arranged above it), attached by means of fixation
    - the first sheet (preferably the second side), mainly in organic glass
    - and / or a connecting piece (7 ') connected to the first sheet,
    - and optionally to the functional element (by its external face), the lid having a general internal face oriented towards the second face, the lid being associated with an interfacial element for interfacial sealing to the fluid (s), mainly the water in liquid or vapor state that is arranged
    - between the cover and the connecting part and optionally between the cover and the functional element (with an edge called the support edge)
    - either integrated into the cover or integrated into the connection part or integrated into the first sheet.
    [0010] Thus, the present invention proposes a durable luminous glazing, even when the glazing is not protected by the body, this thanks to the simple and adapted sealing means, suppressing the fluid diffusion paths (s).
    [0011] The waterproof cover associated with the interfacial seal is easy to be (re) positioned, removable (removable, replaceable at low cost) if necessary:
    - to change the light source (light emitting diodes, etc.) and / or its electronic monitoring components during repair or recycling, or
    - to meet new requirements for optical performance desired by the customer (change in color (s), power, frequency, control) or by the new standards imposed,
    - and / or to add (or add again) sources (LED and / or optical fiber) and / or electronic monitoring in a pane with the cavity and the means
    Petition 870190072528, of 7/29/2019, p. 7/68
    4/29 seal according to the invention.
    [0012] The invention thus facilitates the modularity of the lighting proposed in the pane (lighting pane or that can become lighting, color variation, intensity) - at the level of the logistical management of the flows in production (assembly in advanced deposit and not at the customer's request).
    [0013] The invention reduces the impact of the integration of the source (LED etc.) on the choice of processes and materials and allows one not to be dependent on a realization technology, as it offers a wide range of encapsulation or assembly solutions usable previews.
    [0014] On the other hand, the solution according to the invention is flexible, since the lid can be placed in position regardless of the source (the bar or the LED bars, for example).
    [0015] The invention makes it possible to manufacture a luminous vehicle pane with a possible functional element added on the pane in the usual way, manufactured mainly according to the usual techniques (extruded, molded), the functional element being able to be modified in a way (recess) to support the cover after assembly.
    [0016] The cover, in certain configurations, is not visible after assembly on the vehicle body.
    [0017] On the other hand, the cover and the interfacial sealing element according to the invention are useful, especially for protection against moisture from the source, especially microchips, to prevent pollution of the coupling space (by dirt, pollution mold, ...) and preferably with cleaning products or a high pressure jet wash. This protection must be permanent.
    [0018] To qualify the seal to moisture in the long term, one can use the wet poultice test. The standard D 1165-H7, for example, used in the automobile, describes the H7 wet poultice test.
    [0019] This test consists of immersing the part to be tested in cotton soaked in demineralized water and confining the whole in a bag
    Petition 870190072528, of 7/29/2019, p. 8/68
    5/29 hermetically sealed, and then placed in an oven at 70 ± 2 ° C for 7 days. Then the pieces are extracted, separated from the soaked cotton and placed at 20 ° C for 2 hours. The parts can finally be observed and tested mechanically or functionally to assess the effect of moisture on the system. This test corresponds to several years of natural aging in a humid and hot environment.
    [0020] A high pressure water cleaning test can also be used, such as the D25 5376 high pressure cleaner wash resistance test used in the car: pressure up to 100 bar (10000 kPa) with a nozzle distance / box up to 100 mm.
    [0021] The solution according to the invention, implementing a set of means for sealing, is preferred to a total “monolithic” encapsulation, mainly overmoulding (encapsulated) or by a wrapping with glue, adhesive, in which the light source (such as, for example, the LED bars) would be entirely encapsulated, a solution that would make the light source difficult to access except with its destruction.
    [0022] Furthermore, the total encapsulation is delicate and can cause the source to deteriorate, especially the LEDs (and / or its electronic circuit) already assembled, inducing considerable costs with disposal, except at the expense of precautions that would make the complex manufacturing.
    [0023] Likewise, the integration of the source, such as an LED strip, is difficult or even impossible in the case of an extrusion or a molded part due to the risk of degradation of the light function.
    [0024] In an advantageous and simple way to be carried out, the first sheet is mainly organic glass, mainly PC, with a blind hole in its thickness, on the second face, a setback, for example, to house the source facing the injection edge.
    [0025] In a sheet of organic glass, mainly plastic (PC etc.), a hole, a groove can be produced in practice more easily than in a sheet of mineral glass, especially tempered.
    Petition 870190072528, of 7/29/2019, p. 9/68
    6/29 [0026] In a preferred embodiment, the hole extends around the entire contour of the second face and the cover forms a frame, integrating, above all, the mentioned fastening means (by screwing or snapping, etc.).
    [0027] The cover section can be, for example, L or U, to integrate the fastening means such as, for example, the type of screwing, pressure fitting, rivets, gluing.
    [0028] The pane comprises an element of the source mask and any parasitic light (mainly on the face opposite the extraction face, close to the injection zone) and / or the mask for fixing the pane to the vehicle body by the second face , and the mask element can be:
    - a part of the functional element, mainly a polymeric encapsulation (sufficiently opaque, black),
    - and / or a sufficiently opaque enamel on the periphery of the second face and / or on the first or one face of an added sheet film facing the first, especially when the functional element has one face or two faces,
    - and / or a reflecting surface (layer) on the periphery of the second face and / or on the first face or an added face facing the first face. [0029] More specifically the first sheet is organic, of two materials, transparent and opaque, specially made of polycarbonate:
    - the opaque area of the first leaf on the periphery of the second face and / or on the first face forms a mask of the source and of possible parasitic light (in the vicinity of the injection),
    - and / or forms a mask for attaching the pane to the vehicle body on the second side.
    [0030] It is advantageous that the glazing can contain several sources, mainly groups of diodes distributed over different profiles (therefore several diode bars),
    - a cover and an interfacial sealing element are provided for each group (bar) of diodes,
    - and / or the cover and the interfacial sealing element being common to
    Petition 870190072528, of 7/29/2019, p. 10/68
    7/29 different groups (bars) of diodes.
    [0031] It is preferable that the distance between the inner face of the cover and the first face is less than 10 mm.
    [0032] It is preferable that the distance between the inner face of the cover and the edge or the injection margin is less than 15 mm. The thickness of the lid can be less than 5 mm.
    [0033] On the other hand, the space of the radiation emitted before the injection, of the coupling space naturally varies according to the radiation diagram of the source, defined by a main emission direction and an emission cone.
    [0034] A material for filling the transparent coupling space for the radiation (s) and which is adhesive or not, can be provided, especially:
    - a foam, a thermoplastic resin,
    - an adhesive material, such as glue, that drowns the microchips and fixes them to the pane,
    - a double-sided adhesive, glued to the microchips and the support on one adhesive side and glued to the glass by the other adhesive side.
    [0035] As materials (adhesives, polymers, etc.) that fulfill, if necessary, a short-term sealing function, we can mention:
    - UV crosslinkable glue,
    - a strip (acrylic, PU) with adhesive with acrylic glue,
    - a clear glue, PU, silicone, acrylic,
    - a thermoplastic resin: polyvinyl butyral (PVB), ethylene / vinyl acetate copolymer (EVA).
    [0036] However, the invention allows the avoidance of the addition of an additional element as mentioned above (filler and / or adhesive material and / or sealing material) to perform the optical coupling between the LEDs (bare or pre-encapsulated) and the pane. Such elements create an increase in costs and are liable to modify the color of the light.
    [0037] It is preferable that the space of the radiation emitted before the invention,
    Petition 870190072528, of 7/29/2019, p. 11/68
    8/29 called the coupling or gaseous space (one or more gases, air, for example), and / or the sealing element interfacial to the fluid (s), location, is located on the periphery of the inner face of the cover or on one side of the cap, forming the interfacial sealing element to the fluid (s) a strip.
    [0038] The diodes can be (previously) encapsulated, that is, comprising a semiconductor microchip and a casing, in epoxy or PMMA type resin, for example, which encapsulates the microchip and whose functions are multiple: diffusing or focusing element, wavelength conversion. The enclosure is common or individual.
    [0039] The diodes may preferably be simple semiconductor microchips of the order of hundreds of pm or mm, for example.
    [0040] The diodes can optionally comprise a protective shell (temporary or not) to protect the microchip during manipulation or to improve compatibility between the microchip materials and other materials.
    [0041] The diode can be chosen mainly from at least one of the following light emitting diodes:
    - a side emitting diode, that is, parallel to the electrical contacts (to their faces), with a side emitting side in relation to the support,
    - a diode whose main direction of emission is perpendicular or oblique in relation to the emitting face of the microchip.
    [0042] The emission diagram for a source can be Lambertian.
    [0043] The glazing can thus integrate all the features known in the domain of glazing. Among the features added on the pane we can mention: hydrophobic / oleophobic, hydrophilic / oleophilic layer, anti-dust photocatalytic, stacking that reflects thermal radiation (solar control) or infrared (low emission), anti-reflection.
    [0044] The support profile can be a classic PCB or it can be metallic. The support profile can have a rectangular section.
    [0045] The total number of diodes, the power of the diodes is guided by the size and location of the zones to be illuminated, by the desired luminous intensity
    Petition 870190072528, of 7/29/2019, p. 12/68
    9/29 and the necessary light homogeneity.
    [0046] The length of the support profile varies depending on the number of diodes and the extent of the surface to be illuminated.
    [0047] The LED support profile has a length of the order of 20 cm, for example. Preferably, the number of LED bars (profile + LED) is multiplied to cover the surface.
    [0048] In order to make it more compact and / or to have a simplified design, the support profile may, in addition, have one or more of the following characteristics:
    - be thin, having a thickness mainly less than or equal to 1 mm, or even 0.1 mm,
    - have a metallic surface coating for electrical conduction.
    [0049] Many support profiles of identical or similar diodes can be provided instead of a single support profile, especially if the areas to be illuminated are too far apart or to illuminate a large area.
    [0050] A support profile can be provided with a given reference size multiplied depending on the size of the window and the requirements.
    [0051] To obtain a more compact result and / or to increase the illumination area of the window, the distance between the part of the microchips and the first sheet is preferably less than or equal to 5 mm and the distance between the microchips and the first sheet is preferably less than or equal to 2 mm.
    [0052] The fixation of the source to the glass pane can also be carried out outside the coupling space, especially outside the injection edge and for the diodes by fixing the support profile, mainly by gluing or double-sided adhesive or by pressure fitting on one side of the first sheet, mainly on the second side or on the inner face of the lid.
    [0053] As "permanent" means of fixing the lid, a glue, a weld or a stamping can be chosen, depending on the type of the piece.
    Petition 870190072528, of 7/29/2019, p. 13/68
    10/29 [0054] As "permanent" interfacial sealing means, a glue, a weld can be chosen, and can also consist of the fixing means.
    [0055] However, to facilitate the disassembly or replacement of the lid, the interfacial sealing element, preferably on the periphery of the lid, is a reversible glue that forms part of the fixing means of the lid, therefore reversible or constituting the same, preferably a strip of glue disposed in a strip, mainly in contact with the inner face of the lid or the connecting piece (by means of its free external face) or the second face, mainly two-component epoxy type glue.
    [0056] As a reversible glue, we can mention epoxy adhesives, mainly of two components, such as, for example, the products of the ElectRelease ™ series from EIC Laboratories.
    [0057] Alternatively or cumulatively, to facilitate disassembly and reassembly, the interfacial sealing element, preferably on the periphery of the cover, is a compressed material, the compression sealing of the material being carried out by closing the cover fixing means , the interfacial sealing element being chosen mainly from:
    - a polymeric joint of TPE, for example, of EPDM, mainly a toric joint, with sealing ferrule (s), the joint being mainly arranged in a groove of the cover (on the inner face of the cover or in a groove on one side of the cover) or the second side or the connecting part,
    - a sealing profile on the connection piece, chosen polymeric, edge (s), for example, specially made of EPDM, or on the inner face or on one side of the selected polymeric cover;
    - an optionally glued foam glued (on the cover or on the connecting piece or on the second face) mainly acrylic foam, PU, rubber (EPDM), thermoplastic elastomers, TPE, polyester, mainly polyester single component rubber, such as the Dynafoam product marketed by the firm Saint-Gobain Performance Plastics.
    [0058] The use of sealing adhesive can therefore be dispensed with.
    Petition 870190072528, of 7/29/2019, p. 14/68
    11/29 [0059] In a first advantageous mode, preferably in relation to compression tightness, the fixing means are reversible, the fixing means are chosen from:
    - press-fit means, in points (spurs) or in extension (that is, extending over the entire length of the lid), practiced on the lid (inner face), preferably forming an integral part of the lid (from preference in the tightness zone defined by the interfacial sealing element), and being mainly welded for the pressure fitting in one or more welcoming zones in the first mainly organic sheet, and / or the connecting piece and optionally, still, in the element functional;
    - press-fit means, of the hook type, forming an integral part of the cover, preferably outside the sealing area and being mainly accommodated in one or more housing areas of the first mainly organic sheet and / or the connecting piece and being optionally received still in the functional element;
    - fastening means (such as screw, pin) that protrude from the inner face (housed, for example, in the perforations of the cover or as an integral part of the face cover, optionally through blind holes), preferably in the tightness zone between the interfacial sealing element and the cavity edge.
    [0060] The use of fixing adhesive can therefore be dispensed with.
    [0061] The connecting piece preferably forms a piece excavated from one face with the contour closed like a frame.
    [0062] The cover can be a piece with a generally flat shape). The cover may consist of an adornment (mainly the color of the vehicle body) or be masked after the glazing is attached to the body, cover, for example, along an edge or forming a frame.
    [0063] The cover may also comprise means of preserving the profile and / or a cavity for the passage of connections and / or means for positioning the diode support profile (grooves, local stops, for example, pins).
    Petition 870190072528, of 7/29/2019, p. 15/68
    12/29 [0064] The cover can also comprise:
    - the eventual integration of the wires and electrical connections (from one bar of diodes to the other, for example), prior to the integration of the diodes (overmolding of the wires or prediction of gloves),
    - facilitating the output of the wires in relation to the main power connectors (which may be the battery, a photovoltaic source) at the level of the coverage area by means of an integrated plug pin.
    [0065] It is preferable that the transmission factor of the first leaf around the radiation peak of the microchips (perpendicular to the main faces) is greater than or equal to 50%, being even more preferred that it is greater than or equal to 70%, and even greater than or equal to 80%.
    [0066] The pane can have a protective layer (a leaf, a film, a deposit) on one of the two faces, the first or the second, or that extend on this face. This layer can have a dual function:
    - light diffusion (flexible film of PU, PE, silicone, for example, optionally glued by acrylic),
    - radiation protection (IR, UV): solar control, low emission level,
    - against scratches,
    - aesthetics (colorful, with motifs etc.).
    [0067] Rounded edges can be provided, for example, for the edge or coupling edges of the first sheet. More specifically in the case where the space of radiation emitted is air, it is possible to take advantage of the refraction at the level of the air / first sheet of appropriate geometry (rounded edge, or even beveled) thus allowing the rays to focus within the first leaf. [0068] The glass may optionally have previously undergone a heat treatment of the type of hardening, annealing, tempering, bulging.
    [0069] The glazing is simple, being the first sheet of mineral or organic glass, mainly made of PC, PMMA, PU, ionomeric resin, polyolefin, optionally made of two materials.
    Petition 870190072528, of 7/29/2019, p. 16/68
    13/29 [0070] The glazing can be formed by laminated material (several sheets), being formed:
    - by a first transparent, mineral (floated, etc.) or organic (PC, PMMA, PU, ionomeric resin, polyolefin), thick or thin sheet,
    - an interleaved sheet of the laminated pane, of the material given laminate
    - by a second sheet (opaque or not, transparent, colored, or mineral or organic glass with different functions: solar control ...).
    [0071] As the usual layered glazed material, the flexible PU used, a thermoplastic without plasticizer such as ethylene / vinyl acetate copolymer (EVA), polyvinyl butyral (PVB), can be mentioned. These plastics have, for example, a thickness between 0.2 mm and 1.1 mm, especially 0.38 and 0.76 mm.
    [0072] They can be mainly chosen as first sheet / interleaved sheet / second sheet:
    - mineral glass / interleaved material / mineral glass,
    - mineral glass / interlayered material / polycarbonate,
    - polycarbonate (thick or not) / interlayered material / mineral glass.
    [0073] In the present description, in the absence of precision, a mineral glass is understood as glass.
    [0074] You can cut the edge of the first sheet (contours with cavities before tempering) of a single or sheet pane or by a double pane to accommodate the diodes between the sheets.
    [0075] The first and / or second leaves can have any shape (rectangular, square, round, oval) and be flat or curved.
    [0076] The first sheet may preferably be sodocalcic glass, such as, for example, PLANILUX glass by SAINT GOBAIN GLASS.
    [0077] The second sheet can be colored, from VENUS glass by SAINT GOBAIN GLASS, for example.
    [0078] The laminated pane comprises a second sheet, mainly of
    Petition 870190072528, of 7/29/2019, p. 17/68
    14/29 mineral or organic glass is laminated by a laminated interlayer material to the first sheet, and preferably, the margin of the first sheet comprises a marginal cavity that crosses the thickness in which the source is housed, or the second sheet exceeds the injection edge of the first sheet, creating a lateral indentation of the pane.
    [0079] The glazing may be a multiple insulating, vacuum glazing, mainly of double or triple glass formed:
    - by a first transparent sheet, mineral (floated, etc.) or organic (PC, PMMA, PU, ionomeric resin, polyolefin), thick or thin,
    - by a second sheet spaced by a gas layer (air or inert gas) (opaque or transparent, colored, made of mineral or organic glass, with different functions: solar control),
    - by an eventual third leaf spaced by a gas layer (air or inert gas) (opaque or transparent, colored, mineral glass, or organic, with different functions: solar control).
    [0080] The pane is a multiple pane, mainly a laminated pane, a vacuum or insulating double pane or a triple pane, the first leaf being an external or central leaf of the triple pane.
    [0081] For the extraction of light, diffusion means are employed, either formed by a superficial treatment of the sandblasted glass sheet, acid attack, deposit of enamel or diffusing mastic, or by a treatment in the glass mass of the type of laser engraving.
    [0082] The diffuser layer can be composed of elements that contain particles and a binder, allowing the binder to agglomerate the particles together. The particles can be metallic or metal oxides, the particle size can be between 50 nm and 1 pm, preferably the binder can be mineral to have a heat resistance.
    [0083] In a preferred embodiment, the diffusive layer consists of particles agglomerated in a binder, the particles having an average diameter that is comprised between 0.3 and 2 microns, with the binder present
    Petition 870190072528, of 7/29/2019, p. 18/68
    15/29 in a proportion comprised between 10 and 40% by volume and forming aggregate particles whose size is comprised between 0.5 and 5 microns. This preferred diffuser layer is described specifically in patent application WO 01908787. [0084] The particles can be chosen from semitransparent particles and, preferably, mineral particles such as oxides, nitrides, carbides. The particles are preferably chosen from silicon oxide, alumina, zirconium, cerium titanium or a mixture of at least two of these oxides. [0085] A diffuser mineral layer of approximately 10 pm is chosen, for example.
    [0086] In order to obtain a more compact construction and / or to reduce or increase the illumination area of the glass pane, the distance from the emitting face and the first leaf can be less than 2 mm. Small volume diodes, microchips without a lens and / or without prior encapsulation can be used, for example, mainly those with a width of 1 mm, a length of the order of 2.8 mm, and a height of the order of 1 , 5 mm.
    [0087] The eventual functional element may have one or more standard features for the vehicle glazing.
    [0088] The functionality (single or multiple) of the functional element can be one or more of the following:
    - pane frame (one face, two faces, three faces), mainly with a width on the first face of 3 to 100 mm, with a thickness of 10 to 40 mm, and / or
    - support piece for fastening or centering elements (ie for a good positioning of the pane on the vehicle body during the assembly of the pane in the manufacturer),
    - sealing part against the fluid (s) (liquid water, steam, cleaning products) between the window pane and the vehicle body, limiting at least the passage of fluids between the window pane and the vehicle body ,
    - opaque and / or mask part,
    Petition 870190072528, of 7/29/2019, p. 19/68
    16/29 and / or
    - piece (in points) of conservation of the mechanical elements ("holder" of the side glass).
    [0089] The peripheral functional element is connected to the first leaf. The functional element can be an encapsulated, an extruded, a previously assembled (sealing) joint, a molded, injected part.
    [0090] The functional element is directly on the first sheet or indirectly through a reinforcement element, for example.
    [0091] The functional element can be connected to the glass pane by any means:
    - direct adhesion of the material (molded),
    - compression or insertion,
    - bonding type, etc.
    [0092] The functional element can be single-sided, that is, only:
    - on the second face,
    - on the margin of the first leaf, in the case of a laminated pane or double or triple pane (mainly on buses and rail cars or aircraft), over the entire pane or part of it.
    [0093] The functional element can be:
    - double-sided: on the second side and on the margin, or else on the first face and on the margin,
    - or three-sided: on the first side, on the margin of at least the first leaf (or pane) and on the second face of the first leaf.
    [0094] The functional element on the second face can serve to mask the source and even the stray light.
    [0095] The luminous glazing of the vehicle thus comprises a functional, overmoulded, polymeric element, preferably arranged between the encapsulation and the glazing, mainly of mineral glass, a layer of primary component, of a single component, of two components or three-component, based on polyurethane, polyester, poly (vinyl acetate), isocyanate, for example.
    [0096] As already noted, the functional element can consist of a
    Petition 870190072528, of 7/29/2019, p. 20/68
    17/29 polymeric encapsulation, especially with a thickness of 0.5 mm to several centimeters, obtained by overmoulding.
    [0097] In vehicle applications, the packaging material is usually black or colored (for aesthetic and / or mask purposes). The encapsulation can be made of polyurethane, mainly PU-RIM (reaction in mold). Other overmoulding materials are:
    - flexible thermoplastics:
    - thermoplastic elastomer (TPE), composed mainly of ethylene butadiene styrene SEBS / polypropylene (PP), TPU thermoplastic, PP / EPDM polypropylene.
    - poly (vinyl chloride) (PVC), ethylene-propylene-diene terpolymer (EPDM),
    - rigid thermoplastics:
    - polycarbonate (PC), poly (methyl methacrylate) (PMMA), polyethylene (PE), polypropylene (PP), polyamide (PA66), acrylonitrile butadiene styrene (ABS) and its ABS-PC alloys, polystyrene (PS), copolymer acrylonitrile styrene acrylate (ASA), [0098] The overmoulding material can be colored, have loads of glass fibers.
    [0099] The primary component layer, a single component, two components or three components, is based on polyurethane, polyester, poly (vinyl acetate, isocyanate, for example, ..., having, for example, a thickness of 5 to 50 pm, between the encapsulation and the pane, especially of mineral glass, as this layer favors adhesion to mineral glass.
    [00100] The functional element (overmolded) also brings a good aesthetic finish and allows other elements or functions to be integrated:
    - mold overmoulding,
    - reinforced inserts and inserts for fixing the glazing, in particular for windows that open,
    - sealing profile of multiple ferrules (double, triple ...), which are compressed after assembly on the body,
    Petition 870190072528, of 7/29/2019, p. 21/68
    18/29
    - adornment piece.
    [00101] The overmoulded functional element can have any shape, with or without ferrule.
    [00102] A pipe, also called closed cell sealing profile, can also be attached to the functional element over molded.
    [00103] Preferably, for a ceiling, a level encapsulation is produced, that is, close to one side of the window, preferably to the second face.
    [00104] The luminous pane of the vehicle may comprise a functional element which is a single-sided piece on the second face, mainly an overmoulding or a glued piece (joint, frame), a piece with a fixing bracket (X) of a vehicle element on the pane or the pane on a vehicle element, along at least one injection edge or at least two opposite edges of the pane.
    [00105] The functional element can be a polymeric junction, preferably of elastomer, especially of TPE (thermoplastic elastomer) or EPDM, having a thickness of some mm (typically between 2 and 15 mm).
    [00106] The joint can receive an adhesive for its maintenance. The joint can be attached, preferably, simply by compression or by insertion or by pressure fitting (2 half-frames, for example). The joint can have one face, two faces, three faces. The joint can form a frame. The joint can have any shape: be in L, in U. The joint can be dismountable at any time. It may contain one or more compressed ferrules after fixation.
    [00107] The functional element can be metallic or polymeric, made of polypropylene (PP), polyamide (PA66), poly (butylene terephthalate) (PBT), whether or not containing glass fiber filler.
    [00108] The luminous zone or the luminous zones (especially peripheral along an edge of the pane or opposite or adjacent edges, in band (s), framing the pane) form an internal ambient lighting, an internal reading light by a side window, ceiling ...), a luminous indication of internal and / or external signaling.
    Petition 870190072528, of 7/29/2019, p. 22/68
    19/29 [00109] The luminous zone or the luminous zones are especially peripheral, framing the glass pane (s).
    [00110] The extraction / conversion of radiation (in addition to the type and / or position and / or the number of diodes) are adjusted to:
    - ambient lighting, reading, visible mainly inside the vehicle,
    - a light signal mainly visible on the outside:
    - by activating the remote control: detecting the vehicle in a parking lot or in another location, an indicator of (un) locking doors or
    - safety signs, such as the taillight off,
    - an essentially homogeneous lighting throughout the extraction surface (one or more extraction zones, common or distinct function).
    [00111] The light can be:
    - continuous and / or intermittent,
    - monochrome and / or polychromatic.
    [00112] Visible inside the vehicle, it can also have a night lighting function or a display of information of any nature, such as drawing, logo, alphanumeric signage or other signs.
    [00113] As a decorative motif, for example, one or more luminous bands, a peripheral luminous frame can be formed.
    [00114] A single extraction face can be performed (preferably inside the vehicle).
    [00115] The insertion of diodes in the panes allows the following other signaling features:
    - the display of indicator lights for the driver of the vehicle or passengers (example: engine temperature alarm indicator on the windshield of the car, indicator for commissioning the electric defrost system, the windows ...) ,
    - the display of signaling indicator lights for people outside the vehicle (example: position indicator
    Petition 870190072528, of 7/29/2019, p. 23/68
    20/29 in operation of the vehicle alarm on the side windows),
    - luminous display on the vehicle's glass panes (for example, the luminous display of flasher on rescue vehicles, the safety display with low electricity consumption, indicating the presence of a vehicle in danger). [00116] The glazing can comprise a control signal receiving diode, mainly in the infrared, to control the diodes remotely.
    [00117] The glazing is intended to equip any vehicle:
    - side window of a land vehicle, mainly automobile, utility vehicle, truck, train, mainly with the functional element that is a part of preserving a system for raising glass or with the adornment cover,
    - movable or fixed roof of a land vehicle, mainly automobile, utility vehicle, truck, train, with an optionally curved first leaf, mainly in the case of laminated pane,
    - windshield of a land vehicle, especially a car, utility vehicle, truck, train, especially with the light zone or zones (forming a HUD signal, for example) within or close to the enamel frame, rear bezel mainly inside or close to the enamel frame,
    - window, windshield of an aerial vehicle,
    - window, roof, watercraft, boat, submarine,
    - double or triple glazing on a train, a bus.
    [00118] Naturally, the invention also refers to a vehicle that incorporates the glass pane already defined above.

    [00120] It should be noted that for the sake of clarity, the different elements of the represented objects are not necessarily reproduced in scale.
    Petition 870190072528, of 7/29/2019, p. 25/68
    22/29 [00121] Figure 1 represents a partial schematic sectional view of a luminous pane for vehicle 100 in a first embodiment of the invention.
    [00122] This windowpane 100 is a windowpane comprising a first transparent sheet 1, in rectangular organic glass, for example, having a first main face 11 and a second main face 12, and a margin 10, a polycarbonate sheet in two materials, transparent and opaque, for example.
    [00123] Two support profiles 3 of light emitting diodes 2 extend in the longitudinal direction, for example, and are fixed on the periphery of the second face 12 of the first sheet of glass 1 by a glue 6 or by a double-sided adhesive.
    [00124] Each support profile 3 is monolithic, thin, having a thickness of 0.6 mm (maximum 5 mm, preferably), a width of 7 mm and a length of 20 cm. It can have a rectangular, metallic section or be a classic PCB. The supporting length of the profile on the second face 12 can typically be less than 7 mm.
    [00125] As a variant, the diode support profile has an L, U, J section.
    [00126] More precisely, the diodes are located within a depression 8 (groove) practiced in the opaque zone 1 'of the first sheet (1) on the periphery of the second face (12) and the support profile 3 is supported within a cavity 70 which is wider than the groove.
    [00127] The opaque zone forms a mask for the source 2, extending over the second face it masks any parasitic light, mainly in the vicinity of the injection edge 14 and / or forms a mask of the fixation 91 of the window to the body 90 of the vehicle by the second side 12.
    [00128] Each of the light-emitting diodes contains a microchip emitter 2 capable of emitting one or more radiation in the visible visible spectrum (s) within the first sheet 1. The diodes are small, typically having a few millimeters or less, being mainly 2 x 2 x 1 mm, without optical element (lens) and preferably not encapsulated to reduce the volume as much as possible.
    Petition 870190072528, of 7/29/2019, p. 26/68
    23/29 [00129] In the illustrated configuration, the emitting face 21 is lateral (perpendicular to profile 3). The distance between the lateral emitting face and the injection edge 14 is reduced as much as possible to 5 mm, for example. The main direction of the emission is perpendicular to the face of the semiconductor microchip, having an active layer with a multiple quantum well, for example, of AlInGaP technology or other semiconductors. The cone of light is a Lambertian type cone, of ± 60 °.
    [00130] The extraction of light 12 'can take place through the second face 12 which is, for example, the interior face in the vehicle, mainly in the case of a roof.
    [00131] Extraction 12 'is carried out by any means of diffusion to the surface of the second face 12: sandblasting, acid attack, with diffuser, silkscreen, or as a laser engraving variant on the first sheet 1.
    [00132] For a given group of diodes, a space for the radiation emitted between each diode (microchip) and the injection edge of the first sheet is defined, called the optical coupling space, which is preferably a gaseous medium, typically air .
    [00133] Each microchip and the space of the emitted radiation must be protected against any pollution: water, chemicals etc., this in the long run as during the manufacture of the 100 pane.
    [00134] To guarantee the fluid tightness of each microchip, each diode rod, it is used:
    - a lid (4) of the diodes (a lid for a bar, for example), the face cover having a general internal face oriented towards the first sheet,
    - an interfacial element 5 for producing interfacial tightness to fluid (s), disposed between the inner face of the cap and the second face 12 in the vicinity of the cavity 70, and consisting of a sealing junction made of EPDM, in the form of a 5 mm wide strip seated within a groove 40 on the inner face of the cover, or in a variant, on the first sheet.
    [00135] The cover is a plastic piece of general flat shape, having a rectangular outline (optionally having rounded edges) as shown in Figure 2 or Figure 7. The cover is parallel to the first sheet.
    Petition 870190072528, of 7/29/2019, p. 27/68
    24/29 [00136] As illustrated in Figures 2 and 3, the cover is attached to the first sheet 1, by means of reversible fixation means, by two screws 81, for example, that cross the cover and go beyond the internal face.
    [00137] These screws are accommodated in reception areas of the first sheet 1, more precisely threaded holes 71 and, preferably, between the joint strip and the edge of the cavity 70.
    [00138] The interfacial sealing element 5 is a compressed material, the compression sealing of the material being carried out by a closing effort of the means for fixing the lid 81.
    [00139] The cover is thus easily removable for inserting the diodes or changing them.
    [00140] In a first variant of the cover, shown in figure 4, the cover fastening means are two snap-fit means 82 received in the receiving areas 72, preferably between the joining strip and the edge of the cavity.
    [00141] In another variant of the lid, shown in Figure 5, the means for fixing the lid are two snap-fit means 83 received within the inner edges that delimit the cavity 70.
    [00142] In a variant of the cover (alternative or cumulative) shown in Figures 6 and 7, the support profile 3 of LED 2 is secured by the cover, by hooks 50 ', for example.
    [00143] The cover design thus allows the integration of the diode bar and also allows the focusing of the bar, that is, the good positioning of the bar in relation to the injection margin.
    [00144] The cover may also contain surfaces or stops for reference within the overmoulding housing.
    [00145] In addition, the cover is provided with a cavity 50 (which is made watertight by foam or sealing junction) for the passage of the connections ...
    [00146] In a third cover variant (as an alternative to the second variant) shown in Figure 8, the inner face is provided with a means of positioning (precise) alignment 60 of the profile (3) supporting the diodes, in the form of one
    Petition 870190072528, of 7/29/2019, p. 28/68
    25/29 impeller (concave shape in the opposite direction of sheet 1) that rests on the outermost face of the profile.
    [00147] The design of the cover 4 therefore includes an element 60 that allows an effort to be made on the diode bar previously fixed to the sheet.
    [00148] White or colored light-emitting diodes can be chosen to obtain ambient, reading illumination.
    [00149] Different supports can naturally be provided on different edges and / or having different functions (the choices adapted to the power, the light emitted, the position and the extension of the extraction zones).
    [00150] The extraction, a diffusing layer 12 ', for example, can form an ambient lighting.
    [00151] The pane 100 may form, for example, a fixed panoramic roof of a land vehicle, or in a boat variant. The roof is mounted from the outside on the body 90 by means of an adhesive 91.
    [00152] The first sheet is on the inside of the vehicle. The extraction takes place, preferably, by the face 12.
    [00153] Figure 1c represents a partial schematic view in section of the luminous vehicle pane in a variant of the embodiment of Figure 1.
    [00154] The luminous vehicle pane differs from the pane 100 by the position and the type of interfacial sealing element.
    [00155] Actually, it is a sealing junction 51, in elastomeric rubber or TPE; in a groove 41 practiced on the outer side of the lid 4 and in contact with an edge of the cavity 70.
    [00156] The edges of the inner face simply rest on the first sheet 1 ”in the opaque area.
    [00157] Figure 9 represents a partial schematic cross-sectional view of a luminous pane for vehicle 200 in a second embodiment of the invention.
    [00158] The luminous pane for vehicle 200 differs from the pane 100 initially
    Petition 870190072528, of 7/29/2019, p. 29/68
    26/29 by the arrangement of the fastening means 83, which are pressure-engaging means received on the first sheet on the outside of the cavities 70 and the interfacial sealing element 5.
    [00159] The glazing is provided, for example, with a polymeric overmoulding 7, with a thickness of approximately 2.5 mm, around the glazing, and preferably on the entire periphery of the glazing and at least the second face 12.
    [00160] Overmoulding 7 classically serves as a good aesthetic finish and allows the integration of other elements or functions (reinforcement inserts). [00161] Overmoulding 7 has, for example, a sealing ring between the window and the vehicle.
    [00162] Overmolding 7 is manufactured from black polyurethane, for example, mainly from PU-RIM (reaction in mold in English).
    [00163] Figure 10 represents a partial schematic cross-sectional view of the luminous pane for vehicle 300 in a third embodiment of the invention.
    [00164] The luminous pane for vehicle 300 differs from the pane 100:
    - by the extension of the cavity 70 that reaches the margin 10 and, in addition, because it is over the entire contour of the first leaf as shown in Figure 10bis
    - by the use of a double sealing cord 5 (low excavated area and high non-excavated area of the second face 12
    - the fixing means are reversible, comprising snap-fit means with
    - a first spur 44 in a first receiving groove 141 on the second main face.
    - and a second spur in a second groove 142 on the margin.
    [00165] Figure 11 represents a partial schematic cross-sectional view of a luminous glazing for vehicle 400 in a fourth embodiment of the invention in a variant of glazing 300.
    [00166] The double sealing cord is replaced by reversible 91 'glue and the
    Petition 870190072528, of 7/29/2019, p. 30/68
    27/29 cover is supported on the excavated part. Cavity 70 is partial as shown in Figure 11b. It is possible to choose to fill the lateral ends with glue, preferably reversible.
    [00167] Figure 12 represents a partial schematic cross-sectional view of a luminous pane for vehicle 500 in a fifth embodiment of the invention.
    [00168] The luminous pane for vehicle 500 differs from the pane 100 by choosing a laminated pane
    - the first sheet of silico-soda-lime glass having a thickness equal to 2.1 mm,
    - having a second sheet of glass 17, optionally for a solar control function, colored (VENUS VG10 glass, for example) and / or covered with a solar control coating, having a thickness equal to 2.1 mm.
    [00169] The second sheet of glass is laminated 1 'by an interleaved sheet 8, of PVB 81, for example, having a thickness of 0.76 mm.
    [00170] To mask the source, or even to suppress the parasitic light that leaves the leaf 17, a peripheral mask element 15 on the face 13, in opaque enamel (black), for example and / or a reflector ( silver plating etc.) forming a frame, for example, as shown in Figure 12b.
    [00171] This peripheral mask element 15 can also serve to mask the attachment to the body.
    [00172] The cover 4, attached indirectly to the second face 12, is fixed on a connecting piece 7 'in the form of a frame arranged on the first oval sheet 1, for example. The first face has no cavity.
    [00173] The interfacial seal junction 5 is arranged between the inner face of the cover and the free outer face of the 7 'connection piece of PP, PA66 or PBT material.
    [00174] The reversible fixing means of the lid are means of snapping in points, for example, and disposed on the inner face of the lid, four spurs 83 for example, forming an integral part of the lid (according to Figure 12d ). The inner face of the cover therefore has zones 43 free from
    Petition 870190072528, of 7/29/2019, p. 31/68
    28/29 spurs. Preferably, 50 ”stops are used either to protect or to position diode 3.
    [00175] Press-fit means 83 are attached to the inside of the connection piece 7 'or in a variant to the outside.
    [00176] In a variant, the connection piece is glued to the first sheet (and / or overmoulding).
    [00177] Figure 13 represents a partial schematic cross-sectional view of a luminous pane for vehicle 600 in a sixth embodiment of the invention.
    [00178] Pane 600 differs from pane 100 by the following:
    - its attachment to the body 90 by the glue 91 is made on the first face 11
    - the second face 12 is the external face of the vehicle
    - cavity 70 is a simple groove 8 and the opaque zone is located on face 11 only.
    [00179] It is, for example, a side window, mainly of a car, as shown in Figure 13b.
    [00180] In this case the lid is visible and it also serves as an appearance piece, an adornment, with a curved shape, for example.
    [00181] Figure 14 represents a schematic partial upper cross-sectional view of a luminous pane for vehicle 700.
    [00182] This is, for example, a vehicle rear scope
    - having a luminous area 12 'on the external face 11, therefore seen from the outside (vehicle location means, headlight off.).
    - with a luminous area 12 '' on the inner face 12, therefore inward.
    [00183] Figure 15 represents a partial schematic cross-sectional view of a luminous pane for vehicle 700 in a seventh embodiment of the invention.
    [00184] There is no cavity in the first sheet, the cover is angled and is supported on one side by a three-sided peripheral overmoulding 7 and on the
    Petition 870190072528, of 7/29/2019, p. 32/68
    29/29 second face 12. The sealing and fixing of the cover is produced by glue, preferably reversible and arranged between the ends as shown in Figure 15bis.
    [00185] Figure 16 represents a partial schematic cross-sectional view of a luminous pane for vehicle 800 in an eighth embodiment of the invention.
    [00186] The pane 12 differs from the pane 500 due to the fact that the connection piece is partially connected to the peripheral overmolding (retained within the overmoulding), which can be three-sided and by the position of the press-in means further inward .
    [00187] In a variant the diodes are replaced by an optical fiber with a side emitting fiber side placed (compressed), by a support profile, for example, on the second face. The primary source of light can be a diode (not shown). For example, 3M optical fiber called 3M TM Precision Lighting Elements is used.
    [00188] In a variant, UV LEDs are chosen mainly within the UVA spectrum, to excite the luminophores on the face 12, preferably for a sheet of glass, for example.
