    In an advantageous embodiment of the present invention, a glazing heating zone comprises a plurality of such individual metal wires, called "heating metal wires" which connect the "busbars" to each other. The heating current passes through these individual 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 0.1 mm, in particular between 0.02 and 0.04 mm, and ideally between 0.024 mm and 0.029 mm. 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 laminating interlayer is preferably closer to the diode or diodes and preferably taking into account the positioning tolerance of the diode (s) during the selected cutting preferably wider than the width of the diode or diodes (even if the interlayer has flexibility).

    The gluing is on the whole length or punctual, in zone with diodes and / or outside diodes.
    The diodes are preferably power diodes which are in operation electrically powered under current, preferably with a factor of at least 10 and even at least 20 (thus intensity / 10 or even intensity / 20), especially in order to maintain a temperature below the softening temperature of the polymeric material of the lamination interlayer, in particular at most 130 ° C, more preferably at most 120 ° C and even at most 100 ° C.
    These diodes guarantee excellent efficiency without overheating.

For example, the PCB is disposed along a lateral or longitudinal edge or even more centrally, notably substantially midway between the lateral edges and even closer to the lower longitudinal edge (in the mounted position) than the upper longitudinal edge. Most often, there is an opaque layer opposite F2 and an opaque layer opposite F4 or F3. Their widths are identical or distinct.
    The PCB (at least the zone with the diodes or at least the zone without the diodes if PCB bent in particular in L) can be arranged in or near the region of an opaque layer, in particular an enamel (black), the along a peripheral edge of the laminated glazing, generally face F2 and / or face F4 or face F2 and / or face F3.
    In a first embodiment, the PCB may even be disposed in a region of the windshield in which the outer glass is entirely (or partially) opaque by the opaque layer (the outermost) as an enamel (black) preferably in F2. This opaque layer may be in this region of the windshield a solid layer (continuous bottom) or a layer with savings (surfaces without opaque layer) for example layer in the form of a set of geometric patterns (round, rectangle, square) etc), or not, of identical or distinct size (more or smaller in size away from the wafer and / or patterns of more or more spaced away from the wafer).

This opaque layer, for example, is in the form of a set of opaque geometric or non-geometric patterns (in a circle, rectangle, square, etc.), of identical or distinct size (of a larger or smaller size and / or with patterns of more or more spaced apart from the edge). Areas between the opaque patterns are at the right of the diodes. In these areas can be added a diffusing layer as a white enamel face F4 or F3. The diffusing layer may be spaced or joined with this opaque layer (the innermost). Preferably, the windshield further comprises the opaque layer opposite F2.

    The PCB may be disposed in a region of the rear window or the side window in which the outer glass is opaque by an opaque (outermost) layer such as enamel (black) preferably F2. This opaque layer then comprises at least savings (by a mask deposit or withdrawal including laser) to the right of the diodes. This opaque layer, for example, is in the form of a set of opaque geometric or non-geometric patterns (in a circle, rectangle, square, etc.), of identical or distinct size (of a larger or smaller size and / or with patterns of more or more spaced apart from the edge). Areas between the opaque patterns are at the right of the diodes. In these areas can be added a diffusing layer as a white enamel opposite F2. The diffusing layer may be spaced or joined with this opaque layer. Preferably, the rear window or the side window further comprises the opaque layer opposite F4 (or F3).
    For visual comfort in particular, the windshield may have on the face F3 or (better) the face F4 facing the diodes a diffusing layer, preferably white, especially an enamel (white). For visual comfort in particular, the side window or the rear window may have diodes facing a diffusing layer on the face F2 (or F1), preferably white, especially an enamel (white). It is thus possible to have a set of diffusing patterns (white) of the size of the diodes (preferably of suitable size to prevent the edges from being dark when lit).
    The diffusing layer may be in an area of the clear glass or as already indicated in a peripheral zone with an opaque layer, such as black enamel, with savings to the right of the diodes.
    In particular, for the rear window or the side window, the diodes can be arranged to form one or more letters, a symbol (triangle, symbol of failure or danger etc.), an arrow, using one or more PCBs. .

    The windshield is a laminated glazing unit with light signaling according to the invention - with the aid of a first set of six diodes 4 on a first PCB printed circuit board integrated between the two windows of the laminated glazing, single-row diodes arranged in the window pane in an edge region of the windshield along the lower longitudinal edge possibly in or near a peripheral masking area (opaque enamel ..) of the outer pane (not shown) or even in a zone with alternating masking zone (opaque layer, like an opaque enamel) and transparent zone (facing a diode) of the outer and / or inner glazing, - using a second set of six diodes 4 on a second PCB printed circuit board integrated between the two panes of the laminated glazing, diodes in a row disposed in the clear glass in an edge area of the windshield along the bor d lateral (left), in particular on the driver's side, possibly in or in the vicinity of a masking peripheral zone (opaque enamel ...) of the outer glazing or even in an area with alternating masking zone (opaque layer, such as an enamel opaque) and transparent zone (opposite a diode) of the outer and / or inner glazing. - Using a third set of six diodes 4 on a third printed circuit board called integrated PCB between the two panes of the laminated glazing, diodes in a row disposed in the clear glass in an edge area of the pare -brise along the right side edge including passenger side, possibly in or near a masking peripheral area (opaque enamel ...) of the outer glazing or even in an area with alternating masking area (opaque layer, as an opaque enamel) and transparent area (opposite a diode) of the exterior and / or interior glazing
    These diodes in particular of the first set can emit red light alerting the driver when the car before (or any other means of locomotion or an animal) is detected too close. The red light can be continuous or flashing. The selected continuous light may increase in intensity as the car ahead is near or from a predetermined distance known as high-risk distance. The blinking chosen light frequency may increase as the front car is near or from a predetermined distance known as high-risk distance.
    When the front car is far enough away (respect of the safety distance), the diodes are off.
    These diodes in particular the second set can emit red light alerting the driver when a car (or any other means of locomotion or an animal) is detected too close on the left side of the car. The red light can be continuous or flashing. The selected continuous light may increase in intensity as the car on the side is near or from a predetermined distance known as high-risk distance. The chosen blinking light frequency may increase as the car on the side is near or from a predetermined distance known as high-risk distance. When the car on the side is far enough away (respect of the safety distance), the diodes 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 locomotion or an animal) is detected too close on the right side of the car. The red light can be continuous or flashing. The chosen continuous light may increase in intensity as the car on the side is near or from a predefined distance called high-risk distance. The chosen blinking light frequency may increase as the car on the side is near or from a predetermined distance known as high-risk distance. When the car on the side is far enough away (respect of the safety distance), the diodes are off.
    The anti-collision system works on any road: highway, in town. It can also be used to warn of the presence too close of an object or a pedestrian.
    The signal light may also change from a color (eg orange or amber) when the vehicle at a risky distance to another color eg red when the vehicle at a shorter distance even more dangerous.
    In these cases, as many diodes as necessary are provided, for example a row with an alternation of red diodes and orange diodes, or one row per color. One can also have at least three levels of signaling (three colors).
    The vehicle integrates at least one sensor (preferably one per set of diodes) to detect these dangerous situations (non-compliance with the safety distance or other) and at least one control unit for driving the diodes.
    The diodes are not necessarily in a row, in particular parallel to the edge of the glazing.
    The PCB or PCBs with diodes is preferably in the lower quadrant on the driver side. Being in the clear glass is preferred a transparent PCB.
    The windshield comprises a set of metal wires 5, almost invisible, for example 50pm which are placed on a side face F3 side of the lamination interlayer (over the entire surface), in the form of straight lines or not .
    Figure 1bis shows another windshield of a motor vehicle, windshield 1000 'with light signaling according to the invention. It differs from that of Figure 1 by the type of signaling and the location of the second and third PCBs.
    The first set of diodes 4c, on a SOC medium, forms a triangle with possibly a central exclamation point. It therefore forms a danger signal
    The second and third set of diodes 4a and 4b, on their support 30a and 30b, form arrows indicating that the flasher is engaged.
    The windshield comprises a set of metal wires 5, almost invisible, for example 50pm which are placed on a side face F3 side of the lamination interlayer (over the entire surface), in the form of straight lines or not .
    Figure 1 'shows another windshield of a motor vehicle on a road, windshield with light signaling according to the invention. It differs from that of FIG. 1 by replacing more peripherally the three PCBs, which may be opaque (opaque support and / or opaque conductive tracks (wires, etc.)). The face F2 comprises a solid black enamel masking frame preferably and the F4 (or F3) face preferably a black enamel masking frame, with openings to the right of the diodes.
    The windshield comprises a set of metal wires 5, almost invisible, for example 50pm which are placed on a side face F3 side of the lamination interlayer (over the entire surface), in the form of straight lines or not .
    Figure 1ter is a schematic front view (face side F1 or face 12) of a rear window with light signaling 300 in one embodiment of the invention.
    In the central zone L3, a third brake light 101 is formed with, for example, six red diodes on the PCB along the upper longitudinal edge.
    In each lateral zone L4, a flasher 102 is formed with, for example, six diodes emitting in the yellow on the PCB along the side edge in play, or a signaling light 103 with, for example, six diodes on the PCB along the lower longitudinal edge in play.
    The windshield comprises a set of virtually invisible metal wires 5, for example 50 μm which are placed on a face F2 side of the lamination interlayer (over the entire surface), in the form of straight lines or not .
    Alternatively, a flashing repeater is formed on a side glazing in the same way.
    FIG. 2 is a schematic cross-sectional view of a windshield with light signaling in a first embodiment of the invention, comprising a curved laminated glazing unit, comprising: a first glazing unit 1, for example made of TSA glass and 2.1 mm thick, forming outer glazing, preferably tinted, with first and second main faces 11, 12 respectively said face Fl - and face F2, and a wafer 10 - a lamination interlayer 20 made of polymeric material, here PVB, preferably clear, submillimeter thickness preferably, for example a PVB (Solutia RC41 or Eastman) of thickness about 0.76mm or alternatively if necessary an acoustic PVB (tricouche or quadricouche) for example d approximately 0.81 mm thick, the face F side side F3 is carrying a set of metal son 5 covering the surface (substantially) especially with respect to the diode or diodes - a second glazing 1 ', form an interior glazing eg TSA glass (or clear or extraclair) and 2.1mm thick or even 1.6mm or even less, with third and fourth main faces 13, 14 respectively said face F3 and face F4, the face F4 optionally coated with a functional layer (low emissivity, etc.), the face F2 and the face F3 being the internal faces 11, 1T of the laminated glazing unit - a set of inorganic light-emitting diodes 4, which are surface-mounted components ( CMS or SMD in English), for example emitting in the red on a printed circuit board called PCB 3, the whole PCB + diodes being of total thickness and2 <e1 and better with e1-et2 of at most 0 , 5mm and preferably from 0.1mm to 0.2mm, the diodes being of thickness e2 and the PCB 3 of thickness e2, with a so-called front face 30 facing the face F3 and a rear face 30 against the face F2 or face 11, each diode having a transmitting face emitting towards the inner glazing 1 ', and each diode having a wafer.
    For each of the diodes, the lamination interlayer has a region 21 comprises a blind opening surrounding the wafer of the diode and in contact with the wafer and even the wall base forming the opening that can be in contact with the diode 4. The lamination interlayer 20 is present between the face F3 and the front face of the PCB on the entire front face of the PCB out diodes, in the laminated glazing. The lamination interlayer 22 is also present between the face F2 and the rear face 30 '.
    The diodes (with a single semiconductor chip here) are square-shaped with a width of about 5mm or less.
    We choose a PCB as thin as possible, flexible and preferably even the most discrete possible (minimum width or even transparency) for example comprising a transparent film such as PET, PEN or polyimide and even for the circuit board connection tracks transparent (rather than copper except to make them sufficiently fine). The PCB protrudes from slot 10.
    The windshield has a black enamel frame 15 in front F2 and a black enamel frame 15 'in front F4.
    FIG. 2a shows an exploded view of this glazing showing the use of two PVB sheets - the acoustic sheet, for example, with the blind holes 20i, with a remaining thickness Hf - the so-called rear leaf 22 on the back side 30 '
    In a variant of FIG. 2 shown in FIG. 2b in an exploded view or in FIG. 2 in assembled view: - the so-called back sheet is replaced by a waterproof adhesive 6 on the rear face 30 '- a saving 15a is made in the enamel layer 15 'on the face F4 to let the light of the diode 4 more peripherally here - possibly the flexible diode support is opaque (because masked by the layers 15'.
    In a variant of FIG. 2, shown in FIG. 2, in exploded view: the diode support 3, flexible and transparent, with a conductive (transparent) layer 33 is no longer local but covers the main faces, for example to a solar control function - the two layers of PVB 21, 22 are here disjoint
    In a variant of Figure 2a shown in Figure 3a exploded view: - the leaf with the blind openings is corner, the diodes are in particular in the upper part 21a of the windshield thicker than the lower part 21b.

    In a variant of FIG. 5a shown in FIG. 5b in an exploded view, the electroconductive (and possibly solar control) layer 18, for example opaque, such as a silver enamel, is on the masking enamel 15.
    In a variant of FIG. 2 shown in FIG. 6a in an exploded view: the diodes 4 are surface-mounted on an electroconductive layer 18 covering the face F 3 (possibly also solar control) and the diodes are in reverse mounting-the wires 5 are on the FA face F2 side of the PVB interlayer so the blind opening is F3 side.
    In a variant of FIG. 6a shown in FIG. 6b in an exploded view: the diodes remain in reverse mounting the diodes 4 but on a PCB support 2 on the face F3 - a saving 15a is made in the enamel layer 15 'opposite F4 to let the light of the diode 4 more periphery here.
    A diode may be of the "chip on board" type or even more preferably a surface mounted component (SMD in English) then comprising a peripheral envelope (often referred to as "packaging").

A polymeric envelope may eventually settle (the final thickness after lamination may be less than the initial thickness) during the lamination. The (polymeric) envelope may be opaque. The envelope (monolithic or two-piece) may comprise a base portion 42 carrying the chip and a flared reflector portion away from the base higher than the chip, and containing a protective resin 43 and / a color conversion function material. The front surface 40 can be defined as the surface of this material covering the recessed chip or at the "front" surface of the reifector.
    The diode may comprise a protective resin or a color conversion function material even just on the semiconductor chip. The semiconductor chip can be embedded in a material (resin, etc.).
    The anode and cathode contacts 44 on an insulated layer 33 '. The contacts are extended by "via holes" in the base to layer areas 44, one connected by a wire to the cathode.
