    [0001] The invention relates to a glazing for luminous signaling as well as to a vehicle comprising such a glazing unit and to the manufacture of such a glazing unit. Windshields are increasingly integrating head-up displays ('HUD'). DE102013003686 discloses a light laminated glazing forming a windshield or rear window of a motor vehicle incorporating diodes on a printed circuit board (PCB for printed circuit board in English) to deliver warning light signals to the driver. More precisely in the embodiment in connection with Figure 2 of this document, the windshield light signaling comprising: - a laminated glazing comprising: - a first glazing forming outer glazing with first and second main faces - a spacer laminating - a second glazing forming an internal glazing unit with third and fourth main faces, the second and third faces being the internal faces of the glazing unit - a set of diodes on a printed circuit board capable of emitting a signaling light, red, of warning to the driver - each diode having a transmitting face emitting towards the inner glass, - the lamination interlayer having a through opening formed around the PCB for its integration. The scrap rate of this glazing can be improved and at the same time the reduced manufacturing cost. To this end, the present application has as its first object a vehicle windshield light glazing glazing comprising: a laminated glazing unit comprising: a first glazing unit made of mineral glass, in particular domed glass, forming an external glazing unit, with first and second glazing units; second main faces, respectively face F1 face and face F2 - a lamination interlayer, polymeric material preferably thermoplastic and preferably polyvinylbutyral (PVB), thickness of 3028800 2 plus 1.8mm, better at most 1.2mm and even at most 0.9mm (and better still at least 0.38mm and even at least 0.7mm) - a second glazing, made of mineral glass, in particular domed, forming interior glazing, with third and fourth main faces respectively face 5 F3 and face F4 the face F2 and face F3 being the internal faces of the laminated glazing - a set of inorganic light emitting diodes on a printed circuit board called PCB, suitable for a signaling light, each diode having an emitting face capable of emitting towards the inner glazing, and each diode having a wafer, the lamination interlayer having a through aperture and, according to the invention, for each of the diodes, the lamination interlayer comprises a through opening surrounding the edge of the diode, and in particular in the so-called interdiod space between adjacent diodes, the lamination interlayer is between the face F3 and the front face of the PCB, and better in the laminated glazing, the lamination interlayer being between the face F3 and the front face of the PCB on the entire front face of the PCB out diodes. The total cut around the PCB as practiced in the prior art increases the risk of poor assembly (bubbles, delamination, aesthetic defects). Also, the present invention provides local cutouts of the lamination interlayer. Moreover, the diodes are not in excess relative to the spacer so as not to weaken the glass. Similarly, the present application has the second object a vehicle signal glazing selected from a rear window and a side window 25 comprising: - a laminated glazing comprising: - a first glazing, mineral glass, including domed, forming outer glazing , with first and second main faces respectively said face Fl and face F2 30 - a lamination interlayer, polymeric material preferably thermoplastic and better still PVB, with a thickness of at most 1.8 mm, better from plus 1.2mm and even at most 0.9mm (and better still at least 0.38mm and even at least 0.7mm) - a second glazing, made of mineral glass, in particular domed, forming an interior glazing, with third and fourth main faces respectively face F3 and face F4 3028800 3 face F2 and face F3 being the internal faces of the laminated glazing - a set of inorganic light emitting diodes on a printed circuit board said PCB, able to emit a signaling light, each diode having an emitting face (of a semiconductor chip) capable of emitting in 5 direction of the outer glazing, and each diode having a wafer, the lamination interlayer having A through aperture And, according to the invention, for each of the diodes, the lamination interlayer comprises a through opening surrounding the wafer of the diode, and in particular in the so-called interdiodes space, between neighboring diodes, the lamination interlayer being between the face F2 and the front face of the PCB, and better, within the laminated glazing, the lamination interlayer being between the face F2 and the front face of the PCB on the entire front face of the PCB out of diodes . By side window according to the invention also hears custode. The lamination interlayer is preferably as close as possible to the diodes and preferably with respect to the positioning tolerance of the diodes during the chosen cutting preferably wider than the width of the diodes. In a preferred embodiment, the interlayer Laminating is spaced at most 0.5mm better than at most 0.2 or 0.1mm from the edge of the diodes and even is in contact with the edge of the diodes.
    [0002] In a preferred embodiment, el is subcentimetric, preferably between 0.7 and 0.9 mm (in particular 0.76 mm for conventional PVB and for example 0.81 mm for acoustic PVB), and preferably el-and2. <0.5mm and even preferably el-et2 ranging from 0.1 to 0.3mm. The interlayer may be as thin as possible so as not to risk generating too many air bubbles. It is preferred to use a single sheet (PVB) for the interlayer for economic reasons (material cost and simply a series of local cuts to make). The use of a single sheet (PVB) preferably of standard thickness 0.78 mm or 0.81 mm (for more security rather than 0.38 mm) is made possible by the choice of new ultra-thin power diodes, very recently available on the market. In a preferred embodiment, each diode, preferably of power, being an electronic component including a semiconductor chip, and is equipped with a peripheral, polymeric or ceramic envelope, encapsulating the wafer of the electronic component (and defining the portion of the diode), overflowing 3028800 4 on the front face of the component surrounding the chip, the lamination interlayer (by creep during the lamination) extends to be between said front surface of the envelope and the face F3 of the windshield or the side F2 of the side window or the rear window.
    [0003] The envelope may correspond to the maximum thickness (height) of the diode. The envelope is for example epoxy. 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 diode may be devoid of an optical element (lens, etc.) above the chip-semiconductor to facilitate compactness; however, the optical element may be small enough to be integrated. The diode may comprise a protective resin or a color conversion function material. The semiconductor chip can be embedded in a material (resin, etc.). At the time of contacting the laminating interlayer and PCB, the lamination interlayer may be spaced at most 0.5mm better by at most 0.1mm and after lamination, due to creep the interlayer lamination can be less spaced and even in contact with the slice. Preferably, the diodes are surface-mounted components on the front face of the PCB and even the diodes have Lambertian or near lambertian emission. In a preferred embodiment, the laminating interlayer, of PVB, el ranging from 0.7 to 0.9 mm, the diodes are surface-mounted components on the front face of the PCB, e2 is not more than 0.2mm better than 0.15mm and not more than 0.05mm.
    [0004] The width of the PCB is preferably at most 5 cm, better at most 2 cm, and even at most 1 cm. The width (or length) of a diode with a single semiconductor chip, generally a square diode, is preferably at most 5 mm. The length of a diode with a plurality of semiconductor chips (typically surrounded by the envelope), generally of rectangular shape, is preferably at most 20 mm better than at most 10 mm. The PCB (preferably sufficiently flexible to adapt to the curved laminated glazing) can be glued or pressed against the face F2 for the windshield or the face F3 for the rear window or the side glazing, adhesive bonding (glue or preferably double-sided adhesive), of thickness e3 with e3 <_0.1mm, better e3 <_0.05mm 35 - even such that e3 + e2 of at most 0.15mm better of at most 0.1mm -. With this adhesive one prefers e3-Fet2e1 (especially if present on the back side of the PCB in the area of the diodes). The gluing is on the whole length or punctual, in zone with diodes and / or outside diodes.
    [0005] 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 (thus intensity / 10 or even intensity / 20) particularly preferably maintaining 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 for diodes supplied with current at 1A one chooses between 50 and 100mA. Inorganic diodes are for example based on gallium phosphide, gallium nitride, gallium and aluminum. The PCB can be sufficiently flexible (flexible) to accommodate the curvatures of the curved laminated glazing. In one embodiment, the PCB comprises a plastic film, preferably poly (ethylene terephthalate) or polyimide, provided with preferably transparent conductive tracks and equipped with surface mounted diodes. Polyimide films have a better resistance to the higher temperature compared to the alternative PET or even PEN (polyethylene naphthalate) Preferably, the PCB extends at least to the edge of the glazing Laminated, and preferably protrudes from the wafer, preferably in a better L-shaped bend, and between the rear face of the PCB and the F2 side of the windshield or the F3 face of the rear window or side window. a liquid-impervious adhesive having a thickness of at most 0.1 mm and better still at most 0.05 mm, in particular a double-sided adhesive, is accommodated, and such an adhesive is preferred to an overmolding solution. This is preferably the transparent adhesive used to fix (all) the PCB The bent PCB in particular L-shaped may comprise a first portion (rectangular) carrying the diodes (with the elbow) and a second part for the connectivity (rectangular) opening and even exceeding The second portion may be (much) longer than the first portion.
    [0006] 3028800 6 The glazing (windshield, rear window, side glazing) may have several illuminated displays with the same function or different functions. To have a larger signaling area and / or different colors can be on the same PCB several rows of diodes or 5 to stick two PCBs (at least to join the areas of PCBs with diodes). On a given PCB, the diodes can emit the same light or a different color light, preferably not at the same time. Conventionally, the diodes are in (at least) a row forming a light band along a longitudinal or lateral edge of the windshield (driver's side) or rear window or side window. Naturally, the lamination interlayer may be in direct contact with the face F3 (respectively F2) or with a functional functional coating on this face, in particular a stack of thin layers (including one or more silver layers) such as: heating layer, antennas, solar control layer or low emissivity or a decorative layer or masking (opaque) as a generally black enamel. The PCB (at least the zone with the diodes or at least the zone without the diodes if PCB bent in particular L) can be arranged in or near the region of an opaque layer along a peripheral edge of the glazing laminated, generally facing F2 and / or face F4. The PCB may even be disposed in a region of the windshield in which the outer glass is fully opaque by the opaque layer preferably F2. In this embodiment, the diodes or even the entire PCB is visible only inside, to display the information as a warning (anti-collision) to a driver or even any other person without limiting the driver's view through the windshield. The PCB may even be disposed in a region of the rear window or the side window in which the inner glass is opaque by the opaque layer preferably F4. In this embodiment, the diodes or the entire PCB 30 is visible only outside, to form any kind of fire or information. 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.) using one or more PCBs ... The invention of course any vehicle comprising at least one glazing 35 of light signaling as described above and in particular: 3028800 7 - the windscreen light signaling glazing is an anti-collision means including by detecting a distance to the car of in front of too short and lighting of the diodes preferably in red or, more progressively, in orange (amber) then in red 5 - or the luminous warning glazing forming the rear window is a glazing including a stop 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 marker light of the vehicle - the luminous warning glazing The lateral glazing unit is a glazing unit 10 including a hazard warning light (in the event of a breakdown, etc.) or a vehicle marking light (when stationary, on a parking lot, in the city, etc.), a flashing repeater (near-front side glazing). 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 marker lamps. As diodes can be mentioned the range of OSLON BLACK FLAT sold by OSRAM. For the red light, there may be mentioned as a diode sold by OSRAM: OSLON BLACK FLAT Lx H9PP. For orange light (amber), there may be mentioned as a diode sold by OSRAM: LCY H9PP. For white light, the diode sold by OSRAM is: LUW H9QP or KW HxL531.TE where x = is the number of chips in the diode (for example 4 or 5). Flexible PCBs include the range of AKAFLEX® products (including PCL FW) from 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. A control unit for driving the diodes can be in the laminated glazing or outside the PCB. Finally, the invention relates to a method of the luminous signal glazing as described previously that it comprises the following steps: - automatic cutting (robotic) of the lamination interlayer in the form of a single sheet (PVB preferably) of not more than 0.9 mm to form local through-openings (geometric: round, square, rectangular, in particular of the same shape as the diodes), preferably as many (and not more) openings than diodes, 3028800 8 - assembly of the laminated glazing, with openings opening larger than the size of the diodes preferably greater than 1mm, better 0.5mm or even at most 0.2mm or 0.1mm. The placement of the diodes on the front panel can be manual or robotic (more precise). The present invention is now explained in more detail with reference to the accompanying figures in which: Figure 1 shows a windshield of a motor vehicle on a road, windshield with light signaling according to the invention.
    [0007] Figure 2 is a schematic cross sectional view of a light-signaling windshield in a first embodiment of the invention. Figure 3 shows a perspective view of a diode used in this first mode. Figure 4 shows a partial schematic view from above of the windshield of this first mode. Figure 5 is a schematic cross sectional view of a windshield with light signaling in a second embodiment of the invention. Figure 6 is a schematic view of the manufacture of the windshield of Figure 2.
    [0008] Fig. 7 is a schematic front view of a light-signaled rear window in a third embodiment of the invention. Figure 1 shows (from the vision of the interior of the vehicle) a windshield 1000 of a motor vehicle rolling on a three-lane road with a car in front. 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, 30 diodes in a row disposed in the clear glass in an edge region of the windshield along the lower longitudinal edge optionally in or near a masking peripheral zone (opaque enamel ..) of the outer glazing or even in a zone with alternating masking zone and transparent zone (facing a diode) of the outer and / or inner glazing, 35 - using a second set of six diodes 4 on a second so-called printed circuit board integrated PCB between the two panes of the laminated glazing, 3028800 9 diodes in a row arranged in the clear glass in an edge zone of the windscreen along the lateral edge possibly in or near a zone masking device (opaque enamel ...) of the outer glazing or even in a zone with alternating masking zone and transparent zone (opposite a diode) of the outer and / or inner glazing. These diodes can emit red light alerting the driver when the front car is detected too close. The red light can be continuous or flashing. The selected continuous light may increase in intensity as the front car is near or from a predefined 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.
    [0009] The signaling 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 required are provided, for example a row with alternating red diodes and orange diodes or one row per color. The vehicle integrates at least one sensor to detect these dangerous situations (non-respect of the safety distance or others) and at least one control unit for driving the diodes.
    [0010] 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 100, comprising: a first glazing unit 1, for example made of TSA and 2.1mm glass, forming outer glazing 30, with first and second main faces 11, 12 respectively said face F1 - and face F2 - a laminating interlayer 2 made of polymeric material, here in PVB, of thickness el submillimeter preferably, for example a PVB (JPL) of thickness 0.76 mm or alternatively if necessary an acoustic PVB (tricouche or quadricouche) for example of thickness 0.81 mm 3028800 10 a second glazing 1 ', forming internal glazing for example TSA glass and 2.1mm, with third and fourth main faces 11 ', 12' respectively said face F3 and face F4 the face F2 and face F3 being the inner faces 11, 11 'of the laminated glazing 5 - a set of six diod inorganic electroluminescent electrodes 4, which are surface-mounted components (SMD 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 et2e1 and better with el-et2 of at most 0.5 mm and preferably from 0.1 mm to 0.2 mm, the diodes being of thickness e 2 and the PCB 3 of thickness e 2 with a 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 slice, for each of the diodes, interlayer lamination comprises a through opening 20 surrounding the edge of the diode and in contact with the wafer or alternatively spaced at most 0.5mm and better at most 1mm of the wafer. The lamination interlayer 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 diodes (with a single semiconductor chip) are square-shaped in width of the order of 5mm or less. The diodes must not be extra thick, as this may weaken the glass by creating stress points. And preferably the diodes should not be too far apart from the glass as this may create too much air bubbles especially if the lamination interlayer does not flow until the front face of the diodes and the space between diodes and face F3. 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). FIG. 3 shows a perspective view of a diode used in this first mode described in FIG. 2. Each diode is an electronic component 40 including a semi-conducting chip 41, an emitting face 41 ', and is equipped with a peripheral envelope 42, typically polymeric or ceramic encapsulating the edge of the component (and 3028800 11 defining the edge of the diode), projecting on the front of the component surrounding the emitting face. Here, the emitting face is set back from the front surface 42 'of the envelope which thus fixes the maximum thickness e2 of the diode 4.
    [0011] The lamination interlayer (by creep) can extend to be between said front surface 42 'of the envelope and the face F3 of the windshield (or a side F2 of a side window or rear window) generally without reaching the transmitting face. The rear face 3 'of the PCB is against the face F2. As shown in FIG. 4, the PCB 3 extends to the edge 10 of the laminated glazing and protrudes from this edge. It is of angled shape, in L. In the zone opening on the edge, between the rear face 30 'and the face F2 is housed a waterproof adhesive 6 liquid water thickness of at most 0.1mm and better not more than 0.05mm, especially a double-sided adhesive (preferably transparent if in clear glass).
    [0012] As also shown in FIG. 6 concerning the manufacture of this windshield, the bent PCB therefore comprises a first (rectangular) portion 31 carrying diodes 4 (and with the bend) and a second portion 32 for the (rectangular) connection, for example two copper tracks 33 with an insulation line 34 opening and protruding on the edge of the laminated glazing. This second part 20 can be (much) longer than the first part. Before assembly, the lamination interlayer 2, preferably in the form of a single sheet of PVB, has through-openings 20 which are slightly larger than the size of the diodes which are preferably larger than 0.5 mm (especially if diodes mounted manually on PCB) or even at most 0.1mm (especially if 25 diodes automatically mounted on PCB). In a second embodiment, shown in FIG. 5, the windshield 200 differs in that the rear face 30 'is glued to the face F2 by a double-sided adhesive 5, preferably transparent, of thickness e3 tq e3 + e2 of not more than 0.15mm better than 0.1mm in particular e3 <0.05mm, bonding over the entire length (and width) of the PCB or at least in the area with the diodes. Figure 7 is a schematic front view (face side F1 or face 12) of a light-signaled rear window 300 in a third embodiment of the invention.
    [0013] In the central zone 13, 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 14, a flashing light 102 is formed with, for example, six diodes emitting in the yellow on the PCB along the side edge in play, or again a signaling light 103 with, for example, six diodes on the PCB. along the lower longitudinal edge in play. We can resume the laminated glazing described in Figure 2 by reversing the position of the PCB: its rear face is against the face F3. Alternatively, a flashing repeater is formed on a side glazing in the same way.
