    - curved laminated glazing comprising:
    - a first glazing (curved), which is a sheet of glass (preferably with corners, in particular quadrilateral, rectangular) or forming exterior glazing, -in mineral glass, possibly clear, extra-clear or tinted in particular gray or green- with first and second main faces, respectively said face F1 and face F2, and a first section, glazing in particular of thickness E1 which is preferably for automotive glazing of at most 2.5mm, even at most 2.2mm - in particular of 1 , 9mm, 1.8mm, 1.6mm or 1.4mm- or even at most 1.3mm or at most 1mm

    between the face F2 and the face F3 which are the internal faces of the laminated glazing, a laminating interlayer, possibly clear, extra-clear or even tinted in particular gray or green, made of thermoplastic polymer material and better still of polyvinyl butyral (PVB), in particular of thickness E2 which is preferably for automobile glazing of at most 1.8mm, better at most 1.2mm and even at most 0.9mm (and better at least 0.3mm and even at least minus 0.5mm), in particular set back from the edge of the first glazing, for example at most 2mm or at most 1mm and / or set back from the edge of the second glazing, for example at most 4mm or at most 3mm , laminating interlayer having a main face F'2 in adhesive contact with the face F2 (tin face or other face, if float glass) - bare or with a coating - and a main face F'3 in adhesive contact with the face F3 (tin side or other side, if float glass) bare or with a coating - between the sides F2 and F3, inorganic light-emitting diodes, each diode having a light-emitting face opposite the F2 face capable of emitting light (monochromatic, or polychromatic) in the direction of the F2 face, each diode preferably having a thickness E4 of submillimetric preference and better at least 0.2mm
    a support for the diodes, having a main face called the front facing the face F2 and a main face called the rear facing the face F3, the diodes being mounted on the front face, the support for the diodes being flexible, in particular polymeric , of thickness E3 submillimeter and better at most 0.2mm and even at most 0.1mm, the support of the diodes comprising on the front face electrically conductive zones of electrical supply, said electrical tracks, some or all the electrical tracks supplying the diodes.
    The diode support includes:
    - between the faces F2 and F3, a so-called diode area (defining the light area seen from the face F1 side) comprising said diodes, along the second section, of length L0 along the second section (for example taken parallel to the second section) of at least 6cm and even at least 10cm and even at least 15cm, in a strip or in any other geometric form: round, triangle etc, forming a symbol or a pictogram ...) and in particular of width W0 (normal to L0) less than or equal to L0 preferably at most 5cm and even at most 4cm
    - a through feed zone, extending the diode zone and extending towards the second wafer and opening out from the other wafer, comprising a so-called internal feed zone between the faces F2 and F3 defined by a width Wt lower than L0 (for example taken parallel to the second section and / or L0), internal zone extended by a supply zone beyond the other section known as the protruding zone.
    The lamination interlayer is present between the front face and the face F2 and is possibly between the diodes and the face F2.
    The luminous glazing further comprises a liquid waterproof adhesive or even at the time of an injection to make a polymeric encapsulation, waterproof to a liquid polymeric composition such as polyurethane, preferably in the form of a strip, positioned between the face. rear and face F3, in a part of the rear face (leaving a surface of the rear face against the face F3), of thickness E8 submillimetric preferably at most 0.2mm, better at most 0.1mm and better at most 0.05mm - in particular E3 + E8 is preferably at most 0.15mm better at most 0.1mm.
    According to the invention, finally, the total width Wt is at least 5 cm, the through zone is divided into a plurality of bands called tracks carrying electric tracks (preferably all or at least for the majority are carrying electric tracks , for the diodes and / or for other components on the front face) of individual width Wi less than 5cm in the internal zone and preferably of at least 5mm better of at least 1cm, strips with through tracks of the other tranche (in the area above).
    And according to the invention, the lamination interlayer is present in the so-called interband space between bands with neighboring tracks in particular of width W E of at least 5mm and even at most 20cm.
    When there are only a few diodes and other electrical components and / or the integrated diodes are monochromatic, the internal zone consequently comprises few tracks, and can be relatively narrow typically of 2 cm as described in the prior art .
    However, considering the integration of a large number of diodes and / or polychromatic diodes and even other electrical components (of thickness E7 submillimetric if in the diode zone or the internal zone), such as electric microcontrollers, or other resistive or capacitive elements, the number of tracks therefore increases and naturally leads to a larger width, above 5cm.
    If we choose to widen the internal part beyond 5cm, the Applicant has noted that problems arise:
    - To follow the curvature of the curved glazing, the radius of curvature of the windshield is for example between 2 and 12m, the diode support which is initially a flat sheet, forms folds and therefore reveal appearance defects
    the increase in the width of the surface between the rear face and the face F2 (respectively F3 for the second object) which is without adhesive, leads to the mechanical weakening of the laminated glazing curved over its entire surface, and therefore a local fragility ,
    - the increase in the width of the surface between the rear face and the face F2 (respectively F3 for the second object) which is without adhesive, can generate air bubbles which with aging can rise up in the laminating interlayer and generate aspect defects
    - the increase in the width of the surface between the rear face and the face F2 (respectively F3 for the second object) which is without adhesive, can allow water infiltration thus damaging the diodes and / or any electrical component present in the glazing.
    To counteract these problems, the present invention thus proposes to divide the internal part of the PCB into several narrow zones (bands), bringing greater freedom of conformation to the PCB support, which is then better able to follow the curvature of the curved laminated glazing. .
    The diode support (PCB type) according to the invention contains electrical tracks allowing the supply of a large number of diodes or even other electrical components in the internal zone and even outside the lamination.
    The internal zone preferably remains a zone of narrowing of the diode support. The LED zone and the internal zone (and even the LED zone and the entire through zone) can have a general U-shape (two stripes with tracks), in comb (more than two stripes with tracks). The internal zone in a plurality of stripes with tracks can extend over the entire length L0 with strips at regular or irregular intervals, or even extend a portion of the diode zone, for example a central portion (giving support to diodes of general shape in T).
    We may wish to limit the number of strips as much as possible for easier handling, speed of assembly and even space them as little as possible and for discretion or to facilitate connection to the power source.
    Advantageously, the so-called interband space between two bands with neighboring tracks is of width W E of at least 5mm and better and even at most 20cm. W E can be constant. W E can be identical for all the interband spaces along the first section (resp. Second section for the second object).
    For the first object, the diode support can have an extension towards an adjacent edge of the first edge. There can thus be a second diode zone along the adjacent edge with second stripes of tracks like those already described.
    For the second object, the diode support can have an extension towards an adjacent edge of the second edge. There can thus be a second diode zone along the adjacent edge with second stripes of tracks like those already described.
    As for the lamination interlayer, it can be formed from one or more films, for example having a thickness between 0.2mm and 1.1mm.
    The laminating interlayer can be chosen from polyvinyl butyral (PVB), ethylene - vinyl acetate (EVA), polyurethane (PU) or ionomer resin, alone or as a mixture of several varieties of one of them and / or many of them ; the term "varieties" here refers to variations in the rate of plasticizer, ramifications / linearity, average molecular mass of the molecules.
    We may prefer to use a single sheet (of PVB) for the interlayer for economic reasons (material cost and simply a series of local cuts to be made).
    In particular, in one embodiment, the lamination interlayer is formed from a single sheet (clear, extra-clear or even tinted). The use of a single sheet (of PVB) preferably of standard thickness of 0.6 to 0.9mm (for more security rather than about 0.38mm) is made possible by the choice of new power diodes ultra-thin, submillimetric, very recently available on the market.
    The PVB interlayer is optionally acoustic and / or tinted or preassembled first PVB sheet / functional transparent plastic film such as a polyethylene terephthalate film called functional PET (preferably with a functional layer, for example electrically conductive) / second PVB sheet, the second possible sheet is clear or extra clear
    The transparent plastic film can be between 10 and 100 μm thick. The transparent plastic film can be made of polyamide, polyester, polyolefin (PE: polyethylene, PP: polypropylene), polystyrene, polyvinyl chloride (PVC), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), polycarbonate (PC) . A clear film is preferred, in particular PET.
    As it is possible, for example, to use a clear film of coated PET, for example XIR from the company Eastman, a film coextruded in P ET-PM MA, for example of the 3M® SRF type, but also many other films (for example in PC , PE, PEN, PMMA, PVC), which are visually as transparent as possible and do not change in the autoclave with regard to their surface and consistency.
    The acoustic PVB interlayer may comprise at least one so-called central layer of viscoelastic plastic material with vibroacoustic damping properties, in particular based on polyvinyl butyral (PVB) and of plasticizer, and further comprising two external layers in standard PVB, the central layer being between the two outer layers.
    Optionally one or both of the outer layers has a cross section decreasing in a wedge shape from the top to the bottom of the laminated glazing, the layer of viscoelastic plastic material with vibro-acoustic damping properties having a constant cross section from top to bottom. bottom of laminated glazing. As an example of an acoustic sheet, mention may be made of patent EP0844075.
    The PVB interlayer can be in a corner, therefore with a cross section decreasing in a corner shape from the top to the bottom of the laminated glazing to avoid a double image in the case of a head-up display (HUD in English), especially for a windshield.
    Before lamination, the lamination interlayer, preferably made of PVB, may have blind or through holes accommodating the diodes. In curved laminated glazing, the laminating interlayer may still have the through holes (of identical or reduced width) may or, with creep, the laminating interlayer may fill the space between diodes and the face concerned (F3 for the first object or F2 for the second object). Before the lamination, the blind or through opening is preferably of width (and length) of at most 20mm and even at most 15mm and even at most 10mm or 5mm this depending on the width of the diodes which are gradually miniaturize.
    The blind or through openings can be in an optionally acoustic PVB and / or in the corner, in particular in the corner for a windshield, or in a PVB / plastic film / PVB composite element.
    In curved laminated glazing, a blind or through opening is preferably of width (and length) of at most 20mm and even at most 15mm and even at most 10mm or 5mm depending on the width of the diodes which gradually miniaturize.
    For example, it is possible to use a PVB of variety with relatively high creep, or a PVB of acoustic variety, in particular approximately 0.8 mm thick, marketed by the Eastman Company under the registered trademark Saflex®, or even 0.5 mm thick approximately marketed by the Sekisui Company under the registered brand S-LEC®.
    The laminating interlayer (in particular with blind or through holes) may be as thin as possible (relative to the diodes) so as not to risk generating too many air bubbles.
    For vehicle glazing with internal light zone, the distance H between the emitting face of the diodes and the face F3 is preferably not zero (to avoid damaging the diodes) and preferably at most 0.5 mm and even ranging from 0.1 to 0.3mm. And the lamination interlayer is optionally between the diodes (the emitting faces) and the face F3 over a thickness Er preferably not zero and at most 0.5 mm and even ranging from 0.1 to 0.3 mm.
    Similarly, for vehicle glazing with external light signaling, the distance H between the emitting face of the diodes and the face F2 is preferably non-zero and preferably at most 0.5 mm and even ranging from 0.1 to 0.3mm and the lamination interlayer is optionally between the diodes (the emitting faces) and the face F2 over a thickness Er preferably not zero and at most 0.5mm and even ranging from 0.1 to 0.3mm .
    ίο
    Preferably, in particular a motor vehicle windshield:
    - the laminating interlayer is made of poly (vinyl butyral) (PVB) with a thickness E2 of at most 0.9mm,
    - the diodes are of thickness E4 less than E2 preferably at most 0.8mm and even at most 0.5mm
    - the diode support has a thickness E3 of at most 0.1mm and even at most 0.05mm
    - and even the first and second glazing are of thickness E1 and E2 of at most 2.1mm.
    Concerning the stripes with tracks, the width Wi can be identical or adapted according to the distribution of the diodes and / or other (opto) electronic component (s) in the zone with diodes and / or even in the internal connection area.
    For simplicity, one can provide at least one of the following characteristics:
    - the stripes with tracks can be in the projecting zone with the same width Wi,
    - the track strips are in the protruding area of at least 5cm in length and better at least 10cm or 20cm
    - the track strips are in the protruding area connected (at least two by two) over a width D of at least 0.5cm and even at least 1cm (for assistance with assembly, positioning ) and better not more than 5cm then preferably redeployed in (as many) bands towards the terminal part (linked to a connector),
    - the stripes with tracks are rectangular,
    - the edge of the diode zone defines so-called connecting zones between bands with neighboring tracks (first slice side or second slice side respectively) rectilinear or in arc, or also comprises a chamfer or a fillet -on consecutive edges-, this in order to limit the risks of tears,
    - the stripes with tracks are parallel to each other at ± 5 ° and / or are normal to the first section (respectively the second section for the second object) to ± 5 °,
    - in one or all of the strip strips, the distance between the edge of the diode support and the nearest electrical track is less than 1 cm and even less than 0.5 cm.
    For the first object, the liquid waterproof adhesive, preferably double-sided adhesive tape can be of length L8 (parallel to L0, at the first edge) at least equal to Wt and even exceeding on both sides strips with tracks in particular at least 1mm and even at most 5mm. The width W8 (normal to the first section) is preferably at least 1mm.
    For the first object, the rear face and the face F2 are spaced (are not in direct contact) in the zone going from the first edge and to the outermost edge of said adhesive, in particular the adhesive protrudes from the face adhesive back towards the first edge. Preferably, the liquid waterproof adhesive, preferably double-sided adhesive tape, is present on the face F2 beyond the other edge.
    For the second object, the liquid waterproof adhesive, preferably double-sided adhesive tape, may be of length L8 (parallel to L0, at the second edge) at least equal to Wt and even exceeding on both sides. strips with tracks in particular at least 1mm and even at most 5mm. The width W8 (normal to the second section) is at least 1mm.
    For the second object, preferably the rear face and the face F3 are spaced (are not in direct contact) in the zone going from the second edge and up to the outermost edge of said sealing adhesive, preferably double-sided adhesive tape, in particular the sealing adhesive protrudes from the adhesive rear face in the direction of the second edge. Preferably, the liquid waterproof adhesive, preferably double-sided adhesive tape, is present on the face F3 beyond the other edge.
    For simplicity, said liquid waterproof adhesive may be a single double-sided adhesive strip which extends over at least the width Wt, that is to say on the track strips and between the track strips (and even protruding from the two outermost sides).
    Preferably in order to better guarantee sealing, said liquid waterproof adhesive may be a set of individual double-sided adhesive strips, spaced apart, each track strip having an individual adhesive strip.
    In addition, we wish to position the diode zone. Also preferably, the front face includes one or more double-sided adhesive strips, called alignment strips, offset from the (emitting faces) of the diodes and even preferably offset from said liquid waterproof seal, of thickness E'8. submillimetric, better at most 0.2mm and even at most 0.1mm or at most 0.05mm and better with E3 + E'8 is preferably at most 0.15mm better at most 0.1mm in contact with the laminating interlayer, -in contact with the face F'2 of the laminating interlayer for glazing with internal light zone or with the face F'3 of the laminating interlayer for glazing with external signaling.
    In particular, the alignment strip (s) (for example transparent if not masked) are in the diode zone, for example two strips on either side of the row or rows of diodes or of the diode pattern (in particular if the rectangular diode area near the two side ends)
    In particular, the alignment strip (s) are on one or more or all of the strip strips preferably near the diode zone for better handling, for example less than 1 cm from the diode zone.
    For example, one or more double-sided adhesive strips are used, identical in nature and in thickness and even in width to the double-sided adhesive strip forming said liquid-tight adhesive.
    Preferably the waterproof liquid adhesive and the alignment strip (s) hold at a temperature of at least 100 ° C and even at least 150 ° C, in particular support the lamination cycle.
    For example, one (each) double-sided adhesive strip according to the invention (external strip, sealing strip, alignment strip) comprises a polymeric (polyester, for example PET) or metallic substrate with adhesive-coated main faces (for example acrylic). One (each) double-sided adhesive strip according to the invention can be opaque, especially if it is masked.
    If necessary, for example if not masked, the strip (each) double-sided adhesive visible according to the invention is transparent.
    Furthermore, alternatively or cumulatively, in the protruding zone, the diode support can be curved with a so-called terminal part in a zone on the periphery of the face F4, glued with a double-sided adhesive strip called the external strip on the front face of the support diodes for glazing with internal light zone (first object) or on the rear face of the diode support for glazing with external signaling (second object).
    Preferably for glazing with an internal light zone, the zone on the rear face for bonding a metal frame - removable or forming part of the vehicle body - is at least partially opposite the zone of the external strip opposite. before. The width of the bonding (bead of glue) of the metal frame is for example at most 20mm, in particular from 5 to 15mm.
    Preferably for glazing with external signage, the area of the front face for bonding a metal frame - removable or forming part of the vehicle body - is at least partly opposite the area of the external strip on the front face . The width of the bonding (bead of glue) of the metal frame is for example at most 20mm, in particular from 5 to 15mm.
    The metal frame is not necessarily a closed loop around the curved laminated glazing for example is a strip (straight), an L shape, a U shape.
    The terminal part of the diode support can be linked (by clipping, overmold welding etc.) to an electrical connector itself which can be connected to an electrical cable system leading to a diode control unit itself preferably connected to the vehicle battery.
    The electrical connector can be against, glued or spaced from the side F4.
    The distance between the terminal part and the second section of the second glazing is large enough for this terminal part to be accessible during assembly or disassembly. The total length (unfolded) is adjusted so that the protruding area is curved and fixed on face F4, the protruding area preferably has a length of 20 to 150 cm.
    The second glazing may preferably include a local notch. The protruding area of the diode support comes out of the second section via the notch. The depth of the notch can be greater than or equal to the thickness of the protruding area to avoid an excess thickness or that it is visible from the outside in the event of an apparent edge. In practice the depth of the notch is preferably at most 3mm or even at most 1mm and better at least the thickness E3. The notch area leaves the laminating interlayer visible or is devoid (substantially) of laminating interlayer (having a cutout etc.).
    The electrical tracks and the so-called inter-track space between the neighboring tracks can be covered by an electrically insulating material, such as a layer of resin or varnish (liquid deposition, etc.) or a transparent or non-transparent protective film (PET, polyimide, etc.). for example adhesive. This material can be used for masking electrical tracks in particular in the diode zone (the internal zone can be masked otherwise for example by an enamel) and even in the internal zone or even in the protruding zone. For example we choose a layer, like a varnish, opaque (black etc). This layer can be an inorganic or organic layer, in particular of a tinted polymer, for example made of polyethylene or polymethyl methacrylate.
    In a first configuration, the diode zone can comprise several rows of diodes (for example at least 5 or 8 diodes per row), each in electrical contact with at least two electrical tracks, each of the diodes of width W4 of at most 5mm and spaced at most 1cm preferably at most 5 rows. For example, choose two or three rows of diodes (for example 8 diodes per row) 4mm wide and 1cm apart. If you want to limit the width of the diode area, you can limit it to three rows maximum.
    The diode zone can extend over a fraction of the length of the first section and over the entire length, in particular without opening out from the curved laminated glazing. The width (W0) of the diode zone can preferably be at most 10cm and even 6cm.
    In a second configuration, the diode zone can comprise a plurality of diodes emitting polychromatic light, (for example at least 5 or 8 diodes) in particular in one or more rows, each in electrical contact with at least four electrical tracks, each of diodes of width W4 at most 5mm and even at most 1mm or even at most 0.5mm and spaced at most 2cm. For example, choose a row of 8 diodes with width 4mm and spaced 1cm.
    In one configuration, the diodes can form a light pattern, for example a geometric one, in particular a pictogram.
    For a motor vehicle windshield, it can be an arrow, a series of arrows (which light up independently, for example to form a flashing light), an emergency triangle or any other symbol on the state of the car or on external information (accident, anti-collision light alarm, traffic, communication network status, route to be followed).
    For a roof or a side window, this can for example be a luminous circle or circle.
    For a motor vehicle window, it can be an arrow, a series of arrows (which light up independently for example to form a flashing repeater), an emergency triangle or any other symbol on the state of the car or on external information (accident, anti-collision light alarm).
    Between the face F2 or F3, in the diode zone and / or in the internal zone, the diode support may comprise on the front face another or other electronic components of thickness E5 submillimetric and better at most 0, 8mm (and / or less than or equal to the thickness E4 of the diodes) chosen from at least one of the following elements: a resistive element, a capacitive element, a transistor, a microcontroller (to regulate the supply current of the diodes , in order to protect them and even to regulate their luminance), or even an optoelectronic component.
    Of course, the diode support may alternately or cumulatively include the front face in the protruding zone another or other electronic components of thickness E5 submillimetric or not chosen from at least one of the following elements: a resistive element, an element capacitive, a transistor, a microcontroller, an optoelectronic component.
    A diode according to the invention may preferably be a surface mounted component (SMD in English) often comprising a peripheral envelope.
    In a preferred embodiment, each diode, preferably of power, being a component including a semiconductor chip, and is equipped with a peripheral envelope (often called “packaging”), polymeric or ceramic, encapsulating the edge of the component (and defining the edge of the diode), and overflowing on the front face of the component by surrounding the semiconductor chip.
    The diode may include a protective resin or a material with color conversion function even just on the semiconductor chip. The semiconductor chip can be embedded in a material (resin, etc.).
    The diode can be devoid of an optical element (above the semiconductor chip (whether or not embedded in material) to facilitate compactness.
    The envelope can correspond to the maximum thickness (height) E4 of the diode. The envelope is for example made of epoxy. A polymeric envelope may possibly settle (the final thickness after lamination may be less than the initial thickness) during lamination. The (polymeric) envelope may be opaque.
    The envelope (monolithic or in two pieces) may include a part forming a base carrying the semiconductor chip and a part forming a reflector, flared away from the base (higher than the chip),
    Preferably the diodes have a Lambertian or quasi-Lambertian emission.
    We can refer to the book entitled "LEDs for lighting", by Laurent Massol, Dunod edition for the different types of diodes.
    The diodes are emitted from the top (top emitting in English) rather than from the side (side emitting in English).
    The width W4 (and even length L4) of a diode with a single semiconductor chip, generally a square-shaped diode, is preferably at most 5mm and even at most 1mm. The length of a diode (with polychromatic light) with a plurality of semiconductor chips (typically surrounded by the common peripheral envelope), generally of rectangular shape, is preferably at most 20mm better at most 10mm and even at most 5mm.
    The diodes are preferably power diodes which are in operation under electrically powered current, preferably with a factor of at least 10 and even at least 20 (therefore intensity / 10 or even intensity / 20) in particular so as to maintain a temperature below the softening temperature of the polymeric material of the laminating interlayer, in particular at most 130 ° C, better at most 120 ° C and even at most 100 ° C.
    These diodes guarantee excellent efficiency without overheating.
    For example, for diodes supplied with current at 1A, one chooses between 50 and 100mA.
    The inorganic diodes are for example based on gallium phosphide, gallium nitride, gallium and aluminum.

For orange light (amber), we can cite as diode sold by OSRAM: LCY H9PP. For white light, the diode sold by OSRAM can be cited: LUW H9QP or KW HxL531.TE where x = is the number of chips in the diode (for example 4 or 5).
    As flexible PCB we can cite the AKAFLEX® range of products (in particular PCL FW) from the company KREMPEL.
    In one embodiment of the vehicle, it comprises at least one control unit for driving the diodes and even at least one sensor, in particular for detecting dangerous situations. The control unit for driving the diodes can be outside the laminated glazing or even in the laminated glazing, on or outside the diode support.
    The glazing (windshield, rear window, side glazing) may have several light signals with the same or separate functions.
    The diodes can be arranged to form one or more letters, a symbol (triangle, symbol of breakdown or danger etc), an arrow, by using one or more PCB boards ...
    In particular, for the windshield, the diodes can be arranged to form one or more letters, a symbol (triangle, symbol of breakdown or of danger, etc.), one or more arrows (left and right indicative of the indicator), by using one or more PCBs. One can have as many diode support and set of diodes as described above as necessary. For example :
    - a first set along a left lateral edge preferably closer to the lower longitudinal edge than the top,
    - a second set along a right lateral edge preferably closer to the lower longitudinal edge than high,
    - a third set along the lower longitudinal edge, preferably on the driver's side,
    - a fourth set in the center preferably closer to the bottom longitudinal edge than the top
    You can change the color (depending on the security level etc) or even light more or less diodes (depending on the security level) etc.
    The electrical tracks can be strips, in particular thin strips, for example printed or deposited by any other method of deposition by liquid means or for example by physical vapor deposition. The electrical tracks can also possibly be wires.
    The electrical tracks, for example rectilinear, may be metallic, in particular copper or even aluminum, tin, silver or gold. They can be of width Wp of at most 10 mm, better from 0.2 to 2mm, with a masking layer on top if necessary.
    The electrical tracks can also be strips, in particular wider, resulting from the division of an electrically conductive layer (mono or multilayer) metallic (in particular copper or even aluminum, tin, silver) or gold or transparent conductive oxide, division by zones electrical insulation without the electrically conductive material. This is done for example by selective deposition, by attack masking (laser engraving, photolithography, etc.). The electrical insulation zones are, for example, strips of width at most 1 mm and even at most 0.1 mm.
    One or more electrical tracks can transmit data signals.
    In one embodiment, the support for the diodes comprises a plastic film preferably transparent, preferably made of polyethylene terephthalate called PET, a polyester, a polyimide, a polyamide, or also a poly (ethylene naphthalate) called PEN or also a polybutadiene, a poly (vinyl chloride) called PVC, a polycarbonate called PC, or a polyetheretherketone (PEEK), or even an acrylate. Polyimide films have better resistance to higher temperature compared to the PET or even PEN alternative. The support may include several plastic layers.
    The diode support is provided with electrical tracks, in particular metallic or made of transparent conductive oxide, equipped with surface-mounted diodes.
    It is preferred that the conductive tracks and the film are transparent when they are visible, that is to say in the clear view of the glazing. The electrical tracks can be transparent by the transparent material or by their width sufficiently fine to be (almost) invisible.
    On a given diode support, the diodes can emit the same light or a light of different colors, preferably not at the same time.
    Conventionally, the diodes are in (at least) a row forming a light strip along a longitudinal or lateral edge of the windshield (driver side) or of the rear window or of the side window.
    The first glazing may include an opaque layer on the face F2 (enameled frame in general) and the second glazing may include an opaque layer (enameled frame in general) on the face F4 or on the face F3. Their widths are identical or distinct. For example, in particular for a motor vehicle windshield, the width can be from 5 to 20 cm for the lower longitudinal edge, from 2 to 15 cm for the lower longitudinal edge (wider central zone possible), from 1 to 10 cm for a side edge.
    The diode support can be in the clear of glass, spaced or not from the opaque edges (enamelled frame in general). For example, we have the diode support:
    - along a lateral or longitudinal edge
    - Or even more central, notably substantially halfway between the lateral edges and even closer to the lower longitudinal edge (in the mounted position) than to the upper longitudinal edge.
    The diode support (at least the diode zone) can be arranged in or in the vicinity of the region of an opaque masking layer, along a peripheral edge of the curved laminated glazing, generally (enameled frame) opposite F2 and facing F4 or again (enameled frame) facing F2 and facing F3.
    The diode support is polymeric or essentially polymeric, in particular a “sandwich” material, for example including a metal sheet, in particular anti stray light on the rear face of the PCB support.
    The diode zone is preferably in a peripheral zone for example to preserve the clear glass and / or the TL, preferably within 15cm or even 10cm from the edge of the first glazing. For example, the diode support is placed along a lateral or longitudinal edge preferably less than 15cm from the edge or even more central, notably substantially halfway between the lateral edges and even closer to the lower longitudinal edge (in the mounted position ) only from the upper longitudinal edge
    The diode area can be placed in particular in the central area on the upper longitudinal edge side (which is the usual area of the mirror). A masking can be used to hide unnecessary and unsightly parts of the diode support and / or track strips for leave visible from the inside (resp from the outside for the second object) only the diodes. Any process adapted to nature can be used: printing such as inkjet, screen printing, enamel as on the F2 side ...
    The stripes with tracks are for example masked from the inside by a masking layer preferably in enamel preferably on the face F3 or F4 and / or from the outside by a masking layer preferably on the face F2, preferably enamel.
    For glazing with an internal light zone, the diode zone can be opposite a saving of a masking layer preferably in enamel preferably on the face F3 or F4, saving common to the diodes or in several individual savings for the diodes, or for glazing with external light signaling, the diode zone can be opposite a saving of a masking layer preferably on the face F2, preferably enamel, saving common to the diodes or in several individual savings for diodes.
    Common (or individual) savings can lead to clear glass. We can for example reduce the width of the masking layer (enamel) to form the outer edge of the savings in the area opposite the diodes.
    Common (or individual) savings can be rectangular or square for simplicity.
    More precisely, in a first embodiment in relation to the first object, in particular for a windshield or a roof, the support for the diodes can even be arranged in a peripheral region of the curved laminated glazing in which the first glazing is entirely (or partially) opaque with an opaque masking layer (the outermost if another masking layer is on the second glazing side) preferably opposite F2. This layer may be an inorganic layer, preferably an enamel (black or any other color) or organic layer, in particular of tinted polymer, for example made of polyethylene or polymethyl methacrylate.
    This opaque layer may be a solid layer (continuous bottom) and possibly ending with discontinuities, in particular decorative (surfaces without opaque layer) in the direction of the center of the glazing (of the window glass) for example in the form of a set of geometric patterns. (round, rectangle, square etc), or not, of identical or distinct size (of more or smaller size moving away from the edge and / or more or more spaced patterns away from the edge) .
    In this first embodiment, the diodes, or even the diode zone or even all or part of the track strips can be visible only inside:
    - to display information - as a warning (anti collision) to a driver or even to any other person without limiting the driver's view through a windshield.
    - for decorative lighting, for example for a roof
    The second glazing can also be opaque in this region of the laminated glazing curved by an opaque masking layer (the most internal) preferably on the face F4 or on the face F3 and / or on one of the main faces of the lamination interlayer. This masking layer may be an inorganic layer, preferably an enamel (black or any other color), in particular on the face F4 or F3, or organic, in particular of tinted polymer, for example made of polyethylene or polymethyl methacrylate. This opaque layer is preferably a full layer preferably on the face F4 or F3 and which then comprises:
    - at least one individual savings for each diode (by a mask when depositing or withdrawing, in particular laser) leaving the diodes visible
    - or a common savings for a group of diodes or all the diodes in the zone with diodes, leaving visible the diodes.
    The masking layer with spar (s) may extend beyond the edges of the diode area by at least 0.1mm and even by at most 5mm or at most 2mm.
    Next to the diodes, we can add a diffusing layer such as a white enamel on the side F4 or even on the side F3. The diffusing layer can be spaced or joined with this opaque layer (the most internal).
    For visual comfort in particular, the curved laminated glazing may comprise on the face F3 or (better) the face F4 opposite the diodes a diffusing layer, preferably white, in particular an enamel (white).
    More specifically, in a second embodiment, in relation to the second object, the diode support can be arranged in a region of the curved laminated glazing (rear window, side window, or even windshield) in which the second glazing is opaque with an opaque masking layer (the innermost if another masking layer is on the first glazing side) preferably on the F4 side or on the F3 side and / or on one of the main faces of the laminating interlayer . This masking layer may be an inorganic layer, preferably an enamel (black or any other color), in particular on the face F4 or F3, or organic, in particular of tinted polymer, for example made of polyethylene or polymethyl methacrylate.
    In this embodiment, the diodes or even the diode area or even all or part of the track strips is visible only outside, to form any kind of light signaling. This opaque masking layer may preferably be in this region of the curved laminated glazing a solid layer (continuous bottom) and possibly ending in discontinuities, in particular decorative discontinuities (surfaces without opaque layer) in the direction of the center of the glazing (of the window clear). for example in the form of a set of geometric patterns (in the round, rectangle, square etc.), or not, of identical or distinct size (of more or smaller size and / or more or more spaced patterns away from each other of the slice) in particular an enamel.
    The second glazing can also be opaque with an opaque masking layer (the outermost) preferably made of F2.
    This opaque masking layer then comprises at least savings (by a mask when deposited or by removal, in particular laser) leaving the diodes visible. Next to the diodes, we can add a diffusing layer like a white enamel on the side F2 or F1. The diffusing layer can be spaced or joined with this opaque layer.
    The masking layer with spar (s) may extend beyond the edges of the diode area by at least 0.1mm and even by at most 5mm or at most 2mm.
    In particular for visual comfort, the domed laminated glazing for external signaling (lateral glazing, rear window, etc.) may comprise, opposite the diodes, a diffusing layer on the face F2 (or even F1), preferably white in particular an enamel (white). It is thus possible to have a set of diffusing patterns (white) the size of the diodes (preferably of a suitable size to prevent the edges from being dark in the lit state).
    The first glazing like the second glazing can be parallelepipedic, with sheets or main faces preferably quadrilateral in particular rectangular, square or even of any other shape (round, oval, polygonal).
    The first and / or second glazing may (depending on the aesthetic rendering, the desired optical effect) be a clear glass (of light transmission T L greater than or equal to 90% for a thickness of 4mm), for example a glass of standard composition soda-lime like Planilux® from the company Saint-Gobain Glass, or extra-clear (T L greater than or equal to 91.5% for a thickness of 4 mm), for example a soda-lime-silica glass with less than 0, 05% Fe III or Fe 2 O 3 such as Diamant® glass from Saint-Gobain Glass, or Optiwhite® from Pilkington, or
    B270® from Schott, or another composition described in document WO04 / 025334. it is also possible to choose Planiclear® glass from the company Saint-Gobain Glass.
    The glass of the first and / or second glazing may be neutral (without coloring), or (slightly) tinted in particular gray or green, such as TSA glass from the company SaintGobain Glass. The glass of the first and / or second glazing may have undergone a chemical or thermal treatment of the hardening, annealing or toughening type (in particular for better mechanical resistance) or may be semi-toughened.
    The light transmission T L can be measured according to ISO standard 9050: 2003 using the illuminant D65, and is the total transmission (in particular integrated in the visible range and weighted by the sensitivity curve of the human eye), taking account for both direct transmission and possible diffuse transmission, the measurement being made for example using a spectrophotometer provided with an integrating sphere, the measurement at a given thickness is then converted if necessary to the reference thickness of 4mm according to ISO 9050: 2003.
    The curved laminated glazing according to the invention, in particular windshield or lateral glazing, may have a T L -in the glass clear- which is preferably at least 70% and even at least 75% or even at least 80%.
    The curved laminated glazing according to the invention, in particular glazed roof, can have a light transmission T L of at most 10% and even from 1 to 6%.
    For a car roof, we prefer at least one or all of the following criteria:
    - an energy transmission T E of at most 10% and even from 4 to 6%,
    - an energy reflection R E (preferably on the F1 side) of at most 10%, better from 4 to 5%
    -and a total transmission of TTS solar energy <30% and even <26%, even from 20 to 23%.

    Table A
    “Vision” glass is suitable for all types of glazing in the vehicle: green / blue / gray and ensures reduced energy transmission (TE). The most popular color for this purpose is green. It was chosen because of its neutral appearance which does not affect the color harmony of a vehicle.
    "Privacy" glass is mass-tinted glazing for thermal comfort and privacy. It is dark green or dark gray tinted glazing. To ensure privacy, this glazing has light transmission values that are below 70%, usually around 55% or less. Due to its dark tint, this type of glass also ensures low UV transmission (UV rays can cause skin irritation).
    In most countries, Venus / Privacy glass is suitable for rear side windows (after pillar B), rear window and roof.
    SGS THERMOCONTROL ® Venus consists of 15 dark gray or dark green tinted glazing. They have all the thermal advantages of "
    Vision ”(SGS THERMOCONTROL ® Type) with improved sun protection:
    - lower values in energy transmission (compared to all other glass solutions),
    - its dark color also blocks UV radiation, which is responsible for the irritation of the skin and discoloration of the passenger compartment,
    - provides greater privacy for vehicle passengers (it is difficult to see through the glass from the outside).
    Preferably the curved laminated glazing forms a windshield for a road vehicle such as an automobile, a truck.
    The bending of the first and second glazing (windshield in particular) can be in one or more directions for example as described in document WO2010136702.
    The area of the main face F1 (windshield or roof in particular) can be greater than 1.5 m 2 and for example be less than 3 m 2 .
    The first section (like the second section) can be a longitudinal section of length Li from 1 to 3 m (in particular for a windshield or a roof or a rear window) or also from 0.1 to 1 m (in particular for a side window )
    The first section (like the second section) can be a lateral section of length Lj from 0.5 to 2.5 m (in particular for a windscreen, in particular a panoramic windscreen or a roof or a rear window) or also from 0.1 to 1 m ( especially for a side window).
    The external glazing may include functional thin layers on one or the other of its faces F1 and F2 or else both: one can cite a hydrophobic or self-cleaning photocatalytic layer on the F1 face.
    In order to limit overheating in the passenger compartment or to limit the use of air conditioning, at least one of the glazings (preferably the outer glass) is tinted, and the laminated glazing may also include a reflective or absorbent layer solar radiation, preferably opposite F4 or opposite F2 or F3, in particular a layer of transparent electrically conductive oxide called TCO layer (opposite F4) or even a stack of thin layers comprising at least one TCO layer, or stacks of thin layers comprising at least one silver layer (in F2 or F3), where each silver layer being disposed between dielectric layers.
    We can cumulate layer (with silver) opposite F2 and / or F3 and TCO layer opposite F4.
    The TCO layer (of a transparent electrically conductive oxide) is preferably a fluorine doped tin oxide layer (SnO 2 : F) or a mixed tin and indium oxide layer (ITO) .
    Other layers are possible, among which the thin layers based on mixed indium and zinc oxides (called “IZO”), based on zinc oxide doped with gallium or aluminum, based on titanium oxide doped with niobium, based on cadmium or zinc stannate, based on tin oxide doped with antimony. In the case of zinc oxide doped with aluminum, the doping rate (that is to say the weight of aluminum oxide relative to the total weight) is preferably less than 3%. In the case of gallium, the doping rate can be higher, typically in a range from 5 to 6%.
    In the case of ΙΊΤΟ, the atomic percentage of Sn is preferably within a range ranging from 5 to 70%, in particular from 10 to 60%. For fluorine-doped tin oxide layers, the atomic percentage of fluorine is preferably at most 5%, generally from 1 to 2%.
    ITO is particularly preferred, in particular compared to SnO 2 : F. With higher electrical conductivity, its thickness can be reduced to obtain the same level of emissivity. Easily deposited by a sputtering process, in particular assisted by a magnetic field, called a “magnetron process”, these layers are distinguished by a lower roughness, and therefore a lower fouling.
    One of the advantages of fluorine-doped tin oxide, on the other hand, is its ease of deposition by chemical vapor deposition (CVD), which, unlike the sputtering process, does not require any subsequent heat treatment, and can be applied. used on the flat glass production line by floating.
    By “emissivity” is meant the normal emissivity at 283 K within the meaning of standard EN 12898. The thickness of the low emissivity layer (TCO etc.) is adjusted, according to the nature of the layer, so as to obtain the desired emissivity, which depends on the desired thermal performance. The emissivity of the low emissivity layer is for example less than or equal to 0.3, in particular to 0.25 or even to 0.2. For ITO layers, the thickness will generally be at least 40 nm, or even at least 50 nm and even at least 70 nm, and often at most 150 nm or at most 200 nm. For layers of fluorine-doped tin oxide, the thickness will generally be at least 120 nm, or even at least 200 nm, and often at most 500 nm.
    For example, the low emissivity layer comprises the following sequence: high index sublayer / low index sublayer / a TCO layer / optional dielectric overlayer.
    As a preferred example of a low emissivity layer (protected during quenching, one can choose a high index sublayer (<40 nm) / low index sublayer (<30 nm) / an ITO layer / high index overlayer (5-15 nm )) / low index overlay (<90 nm) barrier / last layer (<10 nm).
    Mention may be made, as low-emissivity layer, of those described in patent US2015 / 0146286, on the face F4, in particular in Examples 1 to 3.
    In particular, the face F4 of the laminated glazing is coated with a transparent functional layer, in particular low emissivity, preferably comprising a TCO layer, including an area (electrically powered, therefore electrode) forming a touch button (for controlling the first light surface) .
    Naturally, the laminating interlayer can be in direct contact with the face F3 (respectively F2 for the second object) or with a conventional functional coating on this face, in particular a stack of thin layers (including one or silver layers) such as : heating layer, antennas, solar control layer or low emissivity or a decoration or masking layer (opaque) such as generally black enamel or any other color.
    In an embodiment of the present invention, the lamination interlayer has in a heating zone (covering all or part of a main face) a plurality of individual metal wires preferably placed on the main face on the side opposite those, called “metallic heating wires” which connect current supply strips or “busbars” to each other. The heating zone can be in whole or in part in the diode and / or strip zone. Preferably the wires are placed on the main face opposite to that on the front face side of the diode support (therefore face F’3 for the first object and face F’2 for the second object).
    The heating current passes through these individual metal wires. The son are advantageously very thin so as not to, or only very little, deteriorate the transparency of the glass. Preferably, the metal wires have a thickness less than or equal to 0.1mm, in particular between 0.02 and 0.04mm, and ideally between 0.024mm and 0.029mm. The metal wires preferably contain copper, tungsten, gold, silver or aluminum or an alloy of at least two of these metals. The alloy may also contain molybdenum, rhenium, osmium, iridium, palladium or platinum. The metal wires are preferably electrically insulated, for example by means of sheaths. This is particularly useful when the wires are under tension on the glass.
    The invention of course relates to any vehicle comprising at least one light signaling glazing as described above and in particular:
    -the glazing of an internal light zone forming a windshield, light is an anti-collision means (on (auto) road or even in town) in particular by detecting a distance to the car (or any other means of locomotion such as motorbike , bicycle, scooter etc or even an animal) ahead (or an object or a person such as a pedestrian) too short, or by detection of a too short distance from an object or a person or of a car or any other means of transport (bicycle, motorbike, etc.) on the side of the car, left side or right side, and lighting of the diodes preferably in red or, more gradually, in orange (amber) then in red , or even with three or more levels so colors
    or the glazing for external light signaling forming the rear window is a glazing including a brake light (for example at least 60cd), a third brake light (for example between 25 and 80cd), a flashing light (for example at least 50cd), a hazard warning light or a vehicle locator light
    - the external light signaling glazing forming lateral glazing is glazing including a hazard warning light (in the event of a breakdown, etc.) or a vehicle tracking light (at a stop, in a parking lot, in town, etc.) a flashing repeater (front side window - particularly close to the rear view mirror - to be seen when the vehicle is doubled, for example between 0.6 and 20cd).
    It is also possible to form clearance lights, parking lights, side position lights.

    Figure 1 shows (from the inside view of the vehicle) a windshield 1000 of a motor vehicle traveling on a three-lane road with a car in front.
    The windshield is a curved laminated glazing with first and second glazing with internal light signaling visible by transparency from the side of the innermost main face 14 of the internal glazing.
    The windshield includes:
    a first set of six inorganic light-emitting diodes 4 mounted on a first printed circuit board, for example opaque, the diode area of which is integrated between the first and second glazing, diodes for example polychromatic and in a row arranged in an area of edge of the windscreen along the lower longitudinal edge, especially on the driver's side (for an optimized driving aid), diode zone in front of a peripheral masking zone (enamel, etc.) of the first glazing or exterior glazing and behind a peripheral zone masking (enamel, etc.) of the second glazing or interior glazing 1 ′ in which individual savings 61 are made allowing the light from the diodes 4 to pass,
    a second set of six inorganic light-emitting diodes 4 mounted on a second printed circuit board, for example opaque, the diode area of which is integrated between the first and second glazing, diodes for example polychromatic in a row arranged in an edge area of the visor 3058107 breaks along the lateral edge (left), in particular on the driver's side, diode zone in front of a peripheral masking zone (enamel, etc.) of the exterior glazing and behind a peripheral masking zone (enamel, etc.) of the interior glazing in which are provided individual savings letting the light from the diodes.,
    - A third set of six inorganic light-emitting diodes 4 mounted on a third printed circuit board, for example opaque, whose diode area is integrated between the first and second glazing, diodes for example polychromatic in a row arranged in an edge area of the windscreen along the right lateral edge, in particular the co-pilot side, diode zone in front of a peripheral masking zone (enamel, etc.) of the exterior glazing and behind a peripheral masking zone (enamel, etc.) of the interior glazing provided individual savings allowing light from the diodes to pass through.
    These diodes, in particular of the first set, can emit red light alerting the driver when the front car (or any other means of transport or even an animal) is detected too close. The red light can be continuous or flashing. The chosen continuous light can increase in intensity as the car in front is close or from a predetermined distance called the high-risk distance. The frequency of the selected flashing light may increase as the car in front is close to or from a predetermined distance known as the high-risk distance.
    When the car in front is far enough away (respect for the safety distance), the LEDs are off.
    These diodes in particular of the second set can emit red light alerting the driver when a car (or any other means of transport or even an animal) is detected too close to the left side of the car. The red light can be continuous or flashing. The chosen continuous light can increase in intensity as the car on the side is near or from a predetermined distance called high-risk distance. The frequency of the selected flashing light may increase as the car on the side is near or from a predetermined distance known as the high-risk distance. When the car on the side is far enough away, the LEDs are off.
    These diodes in particular of the third set can emit red light alerting the driver when a car (or any other means of transport or even an animal) is detected too close to the right side of the car. The red light can be continuous or flashing. The chosen continuous light can increase in intensity as the car on the right side is near or from a predetermined distance called high-risk distance. The frequency of the selected flashing light may increase as the car on the side is near or from a predetermined distance known as the high-risk distance. When the car on the side is far enough away, the LEDs are off.
    The collision avoidance system works on any road: highway, city. It can also be used to alert of the too close presence of an object, a pedestrian etc.
    The signaling light can also change from a color (for example orange or amber) when the vehicle at a risky distance to another color for example red when the vehicle at a shorter distance even more dangerous.
    In these cases, as many diodes are provided as necessary, for example a row with alternating red and orange diodes or one row per color. You can also have at least three signaling levels (three colors).
    The vehicle incorporates at least one sensor (preferably one per set of diodes having the same function) to detect these dangerous situations (disrespect of the safety distance or others) and at least one control unit to drive the diodes, for example outside the windshield.
    For this warning function, any PCB with diodes is preferably in the lower quadrant on the driver side.
    The diodes 4 are not necessarily in a row, parallel to the edge of the glazing, they can form light patterns, for example pictograms.
    Figure T shows a sectional view of diodes mounted on a diode holder according to the invention.
    The inorganic light-emitting diode 4 is a surface-mounted component (CMS or SMD in English) then comprising a peripheral envelope (often called “packaging”).
    Each diode is an electronic component including at least one semiconductor chip 40, and is equipped with a peripheral envelope 42a (often called "packaging"), polymeric or ceramic, forming a peripheral encapsulation of the wafer 42a of the electronic component. The LED is top emission
    The envelope can correspond to the maximum thickness (height) E2 of the diode. The envelope is for example made of epoxy. A polymeric envelope may possibly settle (the final thickness after lamination may be less than the initial thickness) during lamination. The (polymeric) envelope may be opaque.
    The envelope (monolithic or in two pieces) can comprise a part forming a base 42 carrying the chip 40 and a part forming a reflector moving away from the base and higher than the chip, containing a protective resin 43 and / material with color conversion function. The front surface 41 can be defined as the surface of this material covering the recessed chip or at the level of the "front" surface of the reflector.
    The anode and cathode contacts 44 are made, for example, by conductive bonding to an electrically conductive layer with an insulated area 33 ’. The contacts are extended by conductive holes (or "via hole" in English) in the base up to zones of layers 45, one 45 connected by a wire to the cathode.
    FIG. 2 is a schematic sectional view of a windscreen with internal light signaling 200 in an embodiment of the invention, comprising curved laminated glazing comprising:
    a first glazing 1, for example made of TSA glass of the applicant with a thickness E1 equal to 2.1mm, forming exterior glazing, preferably tinted, with first and second main faces 11, 12 respectively called face F1 - and face F2, and a section 10 a second glazing Γ, forming interior glazing for example in clear or extra-clear glass and 2.1mm thick ΕΊ or even 1.6mm or even less, with third and fourth main faces 13, 14 respectively called side F3 and side F4, the side F4 possibly coated with a functional layer (low emissivity, etc.), and with a second section 10 ′ on the side of the first section preferably set back from the first section, for example at most 1 mm , the face F2 and the face F3 being the internal faces 11, 11 ′ of the curved laminated glazing between the glazings, a laminating interlayer 2 made of polymeric material, here made of PVB, preferably clear or extra-clear, of thicker r E2 submillimetric preferably, for example a PVB (for example RC41 from the company Solutia or Eastman) of approximately 0.76mm or alternatively if necessary an acoustic PVB (three-layer or four-layer) for example of thickness approximately 0.81mm , and even possibly PVB in the corner (for a head-up display), PVB having a main face 21 called F'2 in adhesive contact with face F2 and a main face 22 called F'3 in adhesive contact with face F3 and a wafer 20 on the side of the first wafer 10, called another wafer, the face F'3 on the side of the face F3 optionally carrying a set of metallic (heating) wires covering (substantially) the surface of the windshield, in particular facing diodes, in particular almost invisible wires, for example of 50 μm, in the form of straight lines or not.
    The windshield further comprises a printed circuit card 3 with electrical tracks 33 and carrying in the laminated area a set of inorganic light emitting diodes 4, surface mounted (CMS or SMD in English) on the card 3 and having a light-emitting face opposite the face F3 capable of emitting light in the direction of the face F3, for example emitting in red or in green. The diodes 4 are of thickness E4 less than E2, preferably at most 0.8mm. The distance H between the emitting face of the diodes and the face F3 is preferably not zero and preferably at most 0.5 mm and even ranging from 0.1 to 0.3 mm. The PVB is absent or present between the emitting face of the diodes and the F3 face depending on the manufacturing process.
    The card 3 forming the diode support is flexible, with a thickness E3 submillimetric for example from 10 or 50 to 200 pm, for example a polymer such as a polyimide (and possibly a metallic sandwich sheet). It comprises on the front face 32 on the face side F3 of electrically conducting zones of electric power supply, called electric tracks 33 spaced apart by isolation zones 33 ’, some or all of the electric tracks supplying the diodes. The laminating interlayer is present between the front face 32 and the face F3
    The diode support 3 has several areas:
    - between faces F2 and F3 the so-called diode area 30, comprising said diodes 4 for example two rows of 8 diodes parallel to each other along the first edge, diode area defined by a length L0 of at least 6cm along of the first section, and for example by a width W0 of at most 10cm and even at most 5cm and preferably at least 1cm
    a through power supply zone 34 extending the diode zone 30 and extending in the direction of the first wafer 10 and opening out through the other wafer 20, comprising a power supply zone called internal zone, with the electrical tracks, between the faces F2 and F3, defined by a width Wt (parallel to L0) less than L0, internal zone extended by a supply zone beyond the other section 20 called the protruding zone.
    The internal zone is divided into a plurality of bands called track, carrying electrical tracks, individual width Wi less than 5 cm in the internal zone, bands with open tracks of the other section. The total width Wt of the internal area (sum of Wi) is more than 5cm to increase the number of electrical tracks as much as possible. The track strips are for example in the protruding area with the same width Wi.
    In the internal zone, the lamination interlayer 2 is present on the stripes with tracks and in the space called interband space between strips with neighboring tracks, of width W E of at least 5mm and even at most 20cm.
    In the protruding zone, the support for the diodes 3 is curved with an end portion in a zone on the periphery of the face F4, bonded with a double-sided adhesive strip 83 called the external strip on the front face of the support for the diodes. The curved zone is here set back from the edge 10.
    A zone on the rear face includes an adhesive 91 for fixing a metal frame, for example the bodywork 9 of the vehicle, is opposite the zone of the external strip on the front face for sealing. The glue is for example at least 0.5 mm and at most 5 cm from the second 10 ’edge and between 5 and 15 mm in width.
    The terminal part is linked to a connector 7, for example more than 5cm from the edge 10 ’. Between the curved zone and the metal frame there may be other elements (lip, insert, etc.) which can be fixed on the face F4. The distance of the glue 91 can be adjusted relative to the second section 10 ’.
    The diode support comprises on the front face another electronic component 5 of thickness E5 submillimetric chosen from at least one of the following elements: a resistive element, a capacitive element, a transistor, a microcontroller.
    The windshield further comprises a liquid waterproof adhesive 81, in the form of a double-sided adhesive strip, positioned between the face F2 and the rear face 31 of the diode support in a part of the rear face (leaving a surface of the rear face against face F2). This strip is of submillimetric thickness E8 preferably at most 0.2mm, better at most 0.1mm and better at most 0.05mm, in particular E3 + E8 is preferably at most 0.15mm. Preferably it is present in the laminating zone, exceeds the other edge and even exceeds exceeds the curved area to be sure that from the edge 10 there is no contact rear face and face F2.
    One can choose for example the product 9496LE Clear 3M from the company 3M for this band as for the external band.
    For an alternative glazing with a polymeric encapsulation (for example a roof) such as polyurethane, these double-sided adhesive strips 81, 83 can serve as a seal at the time of an injection of the liquid composition.
    The diode support 3 and in particular the track strips is masked from the outside by a so-called external masking layer 6 in enamel on the face F2. The track strips are masked from the inside by a so-called internal enamel masking layer 6 ’on the face F4 or alternatively on the face F3. The internal edge 60 ′ of the internal layer 60 is set back from the internal edge 60 of the external layer 6 to let the light from the diodes pass.
    As diodes you can choose OSLON Black Fiat LUW H9QP.
    Figure 2 'shows a partial schematic sectional view of a curved laminated glazing of a vehicle with an external light zone in an embodiment of the invention. It differs from that described in FIG. 2 in that the diode support 3 is on the side F3, for example with a row of polychromatic diodes, with the curved zone still going up to the side F4. The front face is oriented on the face side F2. The inner edge 60 of the outer layer 60 is set back from the inner edge 60 'of the inner layer 6' on the face F3 (or in a preferred variant on the face F4) to let the light from the diodes 4 pass.
    FIG. 3 shows a partial schematic sectional view of a curved laminated glazing of a vehicle with an internal light zone in an embodiment of the invention. It differs from that described in FIG. 2 in that the internal edge 60 ′ faces the internal edge 60. The internal masking layer 6 ′ has individual savings 61 to allow the light from the diodes to pass through. The component 5 is out of the leafing in the curved area. As a variant, the internal masking layer is on the face F3. An athermic and / or heating layer 16 is on the face F3 or alternatively on a PET sandwiched in the PVB
    Figures 2a, 2b each show a partial schematic front view of a curved laminated glazing of a vehicle with an internal light zone in an embodiment of the invention. The masking layers on the glazing are not shown to see the elements as well as the part of the electrical tracks going up to the diodes. PVB 2 is set back from the second 10 ’tranche.
    The diode zone 30 is a rectangular strip parallel to the edge 10, of width Wo of 5 cm and of length Lo 10 cm. There are four diodes 4 in a row.
    The through zone 34 comprises on the front face 32 two strips with tracks 341 and 342 with the electrical tracks 33 for example of 1mm and made of copper. Each strip of tracks is folded over on the face F4 14 (front face 32 on the side of the face F4) and is linked to an individual connector 7 (or as a common variant). The curved zone is set back from the edge 10 of the first glazing.
    Figure 2b differs from Figure 2a in that the second glazing has a notch 15 ’for example 2mm in which the stripes with tracks are curved. The PVB 2 set back from the second 10 ’slice may be present in the notch 15’.
    Figures 4i to 4m show in front view internal glazing 1 'with their internal masking layer forming a masking frame 6' in enamel (on the face 14 called F4) and Figures 4'i to 4'm show in front view of the external glazings 1 with their external masking layer on the face 12 called F2 forming a masking frame 6 in enamel masking the diode supports 3.
    The internal edge 60 ′ of the layer 6 ′ may have a transition by gradation of patterns towards the center of the glazing. The layer 60 'has common or individual savings 61, 62' to allow the light from the diodes to pass through the diode zone 30 while masking the three stripes of tracks 341, 342, 343 for example along the lower longitudinal edge or even in a thicker central area of the lower longitudinal edge (location of a mirror, etc.).
    Figures 4'm to 4'n show in front view of the external glazing 1 with their external masking layer on the face 12 called F2 forming a masking frame 6 in enamel masking the strips with tracks 34.

    The through zone 34 of the wafer 10 comprises three strips with tracks 341 to 343 of width 4 cm spaced 1 cm apart. The interband space 351 and 352 is filled with PVB. The rear faces of the track strips are bonded to the face F2 by double-sided adhesive strips 811, 812, 813 or by a common strip 811, for sealing.
    For good positioning, one or more double-sided adhesive strips 821, 822, 823 are placed on the front face 32, of thickness at most 0.2 mm, for example transparent on either side of the rows of diodes or under the innermost row or on the track strips.

    The track strips may have in the opening area on the front side a common or individual double-sided adhesive strip 831, 832, 833. The support 301 to 303 may carry other components 5.
    The edge of the diode zone 30 defines so-called connection zones 350 between bands with adjacent straight tracks (FIG. 6) or even in an arc (FIG. 8).
    In FIG. 9, the support 303 in L and comprises two diode zones each with two strips with through tracks 341 to 344 on adjacent sections of the second glazing Γ. The alignment tape 821 is between the diode areas
    In FIG. 10, the diodes 4 are polychromatic, which implies more electrical tracks 33 (four per diode) on the support 305.
    In FIGS. 11 and 12 the diodes 4 form a light pattern, namely an arrow, just like the diode zone 30 of the supports 306, 307. It is possible to provide cutouts 351.352 (straight, in an arc, etc.) between the rows of diodes.
    FIG. 13 shows a schematic side view F1 of a domed laminated glass roof 2000 mounted on a motor vehicle, roof with two internal light zones in an embodiment of the invention near the edge 60 ′ of the enamel frame 6 ′ .
    In each zone, the diodes 4 form a light pattern 308, 308 ’, namely a circle just like the diode zone 30 of the support 308, 308’. The emerging zone has two strips of tracks 341,342 with a space 351 between them.
