MANUFACTURE The invention comprises a luminous laminated glass roof of a vehicle as well as a vehicle comprising such a roof and the manufacture of such a roof.
There are more and more glazed car roofs, some able to bring the mood light. The light comes directly from the light-emitting diodes inserted into the laminated glazing.
More specifically, the document WO2013189794 in the embodiment in connection with FIG. 1, comprises a luminous glazed automotive roof comprising: a laminated glazing unit comprising: a first glazing unit forming external glazing with first and second main faces often called Fl and F2

Said laminating interlayer is provided between the face FA and the face FB of one or a set of M openings which are preferably through-holes or blind holes, each opening being of width Wa (greater than or equal to the diode assembly and optional collimation optics in the aperture) of at most 20mm and even at most 15mm.
Each diode is associated with a through opening or a blind hole accommodating (surrounding the edge of) the diode and even a collimation optics or in that at least one group of said diodes being associated with a common said common through opening or a hole so-called common blind, housing the group of diodes even a common collimation optics In particular -when the opening is through and the face FB in contact with the face F3, the front surface of) the diode is recessed preferably from the face F3 - when the opening is through, when a diode is in reverse assembly and the face FA is in contact with the face F3, the diode is preferably set back from the face F2 (of the face FA), -when the hole is one-eyed the remaining said bottom thickness Hf is at least 0.2mm.

Also, the present invention provides local cutouts of the laminating interlayer dedicated to the diodes. In particular, it avoids the total cut around the diode support (s) (PCB or printed circuit board) as practiced in the prior art increases the risk of poor assembly (bubbles, delamination, aesthetic defects). In particular the diode support is thin enough not to necessarily add a leaflet type PVB back side. The group of diodes in a common hole can be inscribed on a surface S of width or length of at most 20mm. The lamination interlayer is preferably closer to the diodes and preferably taking into account the positioning tolerance of the twist diodes of the selected cut preferably wider than the width of the diodes (even if the interlayer has flexibility ).
The glazed roof further comprises a set of collimation optics, each collimation optics being associated with a light-emitting diode, called a dedicated diode, in the preferably through aperture or with a group of light-emitting diodes which are in the common aperture preferably through each collimation optics (transparent material), is arranged between the faces F2 and F3, with at least one functional portion between the front surface of the diode and the face F3. The collimation optics makes it possible to increase the light and / or to better manage the light by reading zone between the rear passenger and the front. The opening, preferably a through opening, of the lamination interlayer facilitates its installation, its integration. and improves its performance.
Unexpectedly in the case of a through opening the spacer does not flue enough to interfere with the operation of the collimation optics.
Preferably: the half emission angle of the diodes (at the output of the front surface) is preferably at least 50 ° -the angle of view, at the output of each collimation optics, is at most 40 ;
Preferably, at least one or each collimation optics comprises a functional flat plate partially textured in its thickness, called a textured plate, which has an input face oriented towards the face F2 facing the diode in the preferably through aperture or the group of diodes in the common aperture preferably through and an exit face oriented towards the face F3, texturing forming a set of submillimeter height patterns (less than EA preferably). The textured plate is of width greater than or equal to the width of the front surface of the diode (useful area) in the preferably through aperture or group of diodes in the preferably through common aperture.
The input face is preferably spaced from the front face of the diode in the preferably through aperture or group of diodes in the preferably through common aperture.
Preferably the diode height / air knife input and output / textured packet assembly is at most 1mm even 0,9mm.
The textured flat plate advantageously comprises a plurality of geometric patterns consisting of flat or curved surfaces. It is preferably repetitive geometric patterns, that is to say geometric patterns having substantially the same shape and placed substantially equidistant from each other.
Of course, the shape of the area covered by the textured flat plate is independent of the shape of the patterns.
The height of the textured plate is between 5 μm and 1 mm, preferably between 10 μm and 500 μm, in particular between 20 μm and 300 μm, preferably at least 50 μm and at most 200 μm.
The textured plate has a low roughness so as to avoid any diffusion. Regardless of the roughness, one can set a height or depth of texturing that is equal to the distance between the highest point and the lowest point of a pattern.
The patterns have a size of about 10 pm-500 pm and more preferably between 100 and 300 pm, preferably at least 50 pm.
The textured plate has a partial texturing in its thickness, that is to say with a constant thickness between the smooth face and the closest point of the textured face. Preferably, the remaining (constant) plate thickness is defined as the distance between the lowest point between the textured face (input face if prism network) and the opposite face (input face if prism array). . The remaining thickness is at least 50pm and even at most 200pm.
The textured plate (and even a part carrying it) may be a thermoplastic polymer such as polyurethane or polycarbonate (PC) or polymethylmethacrylate (PMMA). it can be a piece molded PMMA, PC. The texturing can be carried out by rolling ("cast" in English), thermoforming, etching, in particular laser etching for a polymeric material. Depending on the shape of the desired texturing, this process may not necessarily lead to perfect geometric shapes: vertex, rounded edge.
Preferably, the patterns are as close as possible to each other, and have, for example, their bases which are less than 1 mm apart and preferably less than 0.5 mm apart. More preferably, the patterns are joined. Motifs are called Jointives when they touch in at least a part of their surface. It is preferred that the patterns be joined because the surface of the plate is more textured. Some reasons do not allow a total junction between the reasons. This is particularly the case when if the bases are circles even touching, there remains a certain surface between the circles not belonging to the grounds. Total joining means that the outline of the base of a pattern is also part of the contours of its neighboring patterns. Some patterns may be fully joined, so that the entire surface of the plate is part of at least one pattern. This is paving pattern. In particular, patterns based on square or rectangular or hexagonal can be totally joined if they are the same bases. In the case of square or rectangular bases, it is also appropriate for said bases to be aligned so that the patterns are completely joined. In the case of hexagonal bases, it is appropriate that said bases form a honeycomb.
Advantageously, at least one or collimation optics is a preferably monolithic piece or several pieces (two for example) integral in the preferably through aperture, and is mounted on the diode support in the opening preferably passing through common ventuellemeht or mounted on the diode or group of diodes, comprising; the functional part of the collimation optics, in particular a textured plate, a peripheral extension (a return) towards the face F2 along the wafer (of the envelope) of the diode or at least one of the diodes of the group of diodes, in particular of width W of at most 1.5 mm, of at least 0.1 mm and better still of at least 0.5 mm, and even in contact with said wafer and better spaced by at most 2 mm or in contact with the lamination interlayer (with wall forming the opening preferably through).

The textured exit face and / or the peripheral extension being in contact or preferably recessed from the face F3, in particular if raised patterns. The peripheral extension and / or the textured plate may be entirely housed in the aperture, preferably through and possibly common. The peripheral extension and / or the textured plate does not protrude from the face FB. The peripheral extension may be in the form of at least one fixing foot (the L-section piece), preferably at least two fixing feet (the piece is of U-section): - fixing of the optical collimation on the diode, the fixing or fixing feet being on either side of the edge of the diode, spaced from or on the diode support, fixation by force mounting or by sticking preferably outside the front surface of the diode or group of diodes (to keep an inlet air space), - fixation of the collimation optics on each diode of the group of diodes where the fixing feet are on each side and other of the edge of the diode, spaced apart or in contact with the diode support, fixed by force-fitting or by adhesive bonding preferably outside the front surface of the diode or group of diodes (to keep an air gap input), - fixing the collimation optics on the diode support.

The textured transparent film covering the area with all the diodes and may be textured by regions, thus carrying one or more textured regions, each facing a diode or groups of diodes and adjacent regions are smooth (to leave transparency).
The textured clear film may be a plastic film (organic polymer), preferably poly (ethylene terephthalate), polycarbonate, poly (methyl methacrylate), polystyrene.
However, a solution with a set of collimating optics mounted in the preferably through apertures is preferred.

In order to limit heating 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 layer of reflective or absorbent solar radiation, preferably face F4 or face F2 or F3, in particular a transparent electroconductive oxide layer called TCO layer (face F4) or even a thin film stack comprising at least one TCO layer, or d stacks of thin layers comprising at least one layer of silver (in F2 or F3), the or each silver layer being disposed between dielectric layers.
One can cumulate layer (silver) face F2 and / or F3 and TCO layer F4 face.
The TCO layer (of an electrically conductive transparent oxide) is preferably a fluorine-doped tin oxide layer (SnO2: F) or a tin-indium mixed oxide (ITO) layer. Other layers are possible, among which thin layers based on mixed oxides of indium and zinc (called "IZO"), based on zinc oxide doped with gallium or aluminum, based on Niobium doped titanium oxide, based on cadmium or zinc stannate, based on antimony-doped tin oxide. In the case of aluminum doped zinc oxide, the doping level (i.e., the weight of aluminum oxide based on the total weight) is preferably less than 3%. In the case of gallium, the doping rate may be higher, typically in a range of 5 to 6%. In the case of ΓΙΤΟ, the atomic percentage of Sn is preferably in a range from 5 to 70%, especially from 10 to 60%. For the fluorine-doped tin oxide-based layers, the atomic percentage of fluorine is preferably at most 5%, usually 1 to 2%. ITO is particularly preferred, especially with respect to SnO 2: F. Higher electrical conductivity, its thickness may be lower to achieve the same level of emissivity. Easily deposited by a cathodic sputtering method, especially assisted by magnetic field, called "magnetron process", these layers are distinguished by a lower roughness, and therefore a lower fouling.
One of the advantages of fluorine-doped tin oxide is its ease of deposition by chemical vapor deposition (CVD), which in contrast to the sputtering process, does not require any subsequent heat treatment, and can be implemented on the float flat glass production line.
By "emissivity" is meant the normal emissivity at 283 K according to EN12898. The thickness of the low-emissivity layer (TCO, etc.) is adjusted, depending on 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 fluorine-doped tin oxide layers, the thickness will generally be at least 120 nm, even at least 200 nm, and often at most 500 nm.
For example, the low-emissivity layer comprises the following sequence: high-index sub-layer / low-index sub-layer / an optional TCO-dielectric overcoat layer.
As a preferred example of a low-emissivity layer (protected during quenching), it is possible to choose high-index sub-layer (<40 nm) / low-index underlayer (<30 nm) / an ITO layer / high-index overcoat (5-15 nm) )) / overlay low index (<90 nm) barrier / last layer (<10 nm).
As low-emissivity layer, those described in the US2015 / 0146286 patent can be mentioned on the F4 side, in particular in Examples 1 to 3.
In a preferred embodiment: - the first and / or second glazing is tinted and / or the lamination interlayer is tinted on all part of its thickness (especially outside the side of the brightest surface, often the one with the alterations) - and / or one of the faces F2 or F3 or F4 - preferably the face F4 - of the glazed roof, is coated with a low emissivity layer, in particular comprising a transparent electrically conductive oxide layer (TCO ) in particular a thin film stack with TCO layer or a stack of thin layers with layer (s) of silver - and / or one of the faces F2 or F3 or F4 - preferably the face F3 - of the glazed roof, is coated with a solar control layer, in particular comprising a transparent electrically conductive oxide layer (TCO), in particular a thin film stack with a TCO layer or a stack of thin layers with a silver layer (s), and / or or an additional film (polymeric, c Like a tinted PET polyethylene terephthalate etc) is between the faces F2 and F3 or (glued) at F4 or even face Fl.
In particular, the face F4 of the glass, is coated with a transparent functional layer including low emissivity, preferably comprising a TCO layer, including a zone (electrically powered, therefore electrode) forming a touch button (for controlling the first light surface). The invention of course relates to any vehicle having at least one roof as described above.

For the sake of simplicity the roofs are represented planes but are actually curved. The elements are not represented to scale.
FIG. 1 shows a view from above of a luminous laminated glazed roof of a motor vehicle 1000 according to a first embodiment of the invention with two sets of diodes 4 forming for one a reading lamp at the rear and for the other in the front.
A first set 102 of eight diodes 4 (see the detail view) is on a first printed circuit board called PCB (not shown here) integrated between the two glazings of the laminated glazing, eight diodes forming a round arranged in the clear of window in a longitudinal edge area in the vicinity of an outer masking peripheral area (opaque enamel ..) of the outer glazing -and an inner masking area (opaque enamel ..) of similar size of the non-visible interior glazing -
Alternatively, the reading lamp is masked by the layer 15 'and one or more savings are made in the internal masking zone or even is in a (transition) zone with alternating masking zone (opaque layer, such as an opaque enamel) and transparent area of the interior glazing,
Figure 1 'shows a partial schematic sectional view of the laminated glazed roof 100' in a variant of the first embodiment of the invention. The laminated glazed roof 100 ', curved, comprising: a first glazing 1, for example made of VG10 glass and 2.1 mm thick, forming an external glazing unit, with first and second main faces 11, 12, respectively called face Fl, and face F2 - a second glazing 1 ', forming internal glazing for example TSA glass (or clear or extraclair) and 2.1mm thick or even 1.6mm or even less than 1.1mm (chemically tempered glass including ), with third and fourth main faces 13, 14 respectively said face F3 and face F4, the face F3 optionally coated with a functional layer (heating, low emissivity, etc.), - between the face F2 and the face F3 forming the faces 12, 13 of the laminated glazing a laminating interlayer 20 made of polymeric material, here of PVB, of thickness And preferably of about 1 mm or less, having a face FB in adhesive contact with the face F3 and a set of openings crossing es (here two visible) between a face FA against a diode support 3 and the face FB, the thickness Ea between these faces FA and FB corresponds to the height of the openings H for example of about 0.76mm for a conventional PVB ( RC41 of Solutia or Eastman) alternatively if necessary an acoustic PVB (tricouche or quadricouche) for example of thickness 0.81mm about a functional layer 16 for example low emissivity face F4 (ITO etc).
Inorganic light-emitting diodes 4 are surface mounted components (SMD or SMD in English), on the support of diodes, for example emitting in the white.
The diode support may be a printed circuit board called PCB 3 of thickness e2 of at most 0.2 mm and preferably from 0.1 mm to 0.2 mm.
The so-called front face 30 of the diode support 3 carries conductive tracks opposite the face F3 and the rear face 30 'is against the face F2 or face 12. Each diode has a transmitting face emitting towards the inner glazing 1' , and each diode having a slice.
For each of the diodes, the lamination interlayer thus comprises a through opening 20a surrounding the wafer of the diode and even in contact with its wafer or alternatively spaced apart by at most 0.5 mm and even at most 0.1 mm from the slice.
The diodes 4 (with a single semiconductor chip here) are of square shape with a width of the order of 5 mm or less. The diodes are of thickness e2 less than the height of the hole H. The diodes are not in excess thickness at the risk of weakening the glass by creating points of stress. And the diodes preferably should not be too far from the face F3 at the risk of creating too much air bubbles.
We choose a PCB as thin as possible, flexible and in the case shown here or the diodes 4 are in the glass clear (out of the periphery with the external and internal masking layers 15 and 15 ') even preferably the most discrete possible (minimum width or even transparency) for example comprising a transparent film such as a PET, PEN or a polyimide and even for the printed circuit transparent connection tracks (rather than copper or other metal except to make them sufficiently thin) .
During manufacture, for example, a first sheet 21 with the through openings and a second sheet of PVB 22 on the back side of the PCB are chosen. By creep the two sheets are contiguous with or without a discernable interface (here in dashed lines).
To better direct the light beam, it is further used for each reading-function diode, a collimating optics 5 housed in the through opening accommodating the diode, optical collimation mounted on the support 3 or on the diode itself.
The layer 16 may have a touch switch area to turn on the reading light.
Figure 1 "shows a partial schematic sectional view of the laminated glazed roof in a variant of Figure T in which - a functional layer 17 for example a heating layer is in front F3. the layer opposite F4 is eventually removed
The layer 17 may have a touch switch area to turn on the reading light.
It is possible to add on the support 3 a light indicator diode of the touch switch zone and its associated through opening.
Figures 1a, 1b, 1c, 1c show front views of diode-side supports on the inner side (facing the passenger compartment) with different arrangements of diodes.
The PCB 3 comprises a first diode-carrying part and a smaller portion of power supply opening beyond the edge of the roof. in the figure we use nine diodes including eight diodes 4 in round forming a reading light and a central 4'b forming light indicator in Figure 1b nine diodes are used including eight diodes 4 in round forming a reading light and a central 4 'forming a light and part is hollowed out 3d of the support for more discretion in Figure 1c we use fifteen diodes including fourteen diodes 4 squared reading and a central 4 'forming a light indicator in Figure 1d we use seventeen diodes including sixteen diodes 4 cross reading and a center 4 FIG. 1 shows a row of six diodes 4 and, for example, the support 3 is bent, in L, with an adhesive 6 for sealing against the face F 2, FIG. adding the sheet 21 with the through openings 20.
FIG. 1a shows a partial diagrammatic sectional detail view of the laminated glazed roof 200 'according to one embodiment of the invention.
Each diode, preferably of power for the reading light, is an electronic component including the semiconductor chip 41, and is equipped with a peripheral envelope 42 (often called "packaging"), polymeric or ceramic, encapsulating the edge of the electronic component The lamination interlayer (by creep during the lamination) may extend to be between the so-called front surface 42 'of the envelope and the face F3 without going to the front face 40 of the diode (emitting face of the chip or more precisely face of the chip assembly and protective covering material or 43 wavelength conversion function (phosphor) .The envelope may have a flared profile 42a away from the chip 41.
The electronic component 4 thus generally comprises a base 42b here called lower part of the carrying envelope of the chip-semiconductor and a reflector flared towards F3, here an upper portion 42a of the envelope.
The material 43 may be a transparent resin and / or a mixture with a luminophore
The phosphor may be just on the chip 41. The material 43 may be flush with the surface (reflector) 42a, including creating an air gap that may be useful.
Examples of diodes are described in the document "leds for the lighting of Laurent Massol" Edition dunod on pages 140; The lamination interlayer may extend to be between said front surface 42 'of the envelope and the face F3 without being in contact with the emitting face of the chip or the surface 40. The envelope is for example epoxy or ceramic. 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.
On the rear face of the diode (of the envelope), there are two electrical contact surfaces 44 on zones 33 (isolated by etching 33 ', etc.) of an electroconductive layer 33 on the support 3.
The piece 5 comprises the textured face here network of hollow pyramids and a peripheral extension 53 preferably in the form of an entourage or hollow body for attachment to the support of diodes 3 for example by an adhesive 61, and / or diode , and / or for PVB barrier (as a precaution).
The piece 5 has for example a square outline. It is for example made of PMMA and obtained by molding. The walls 53 are preferably in contact with the PVB (cavity forming the through opening). The part 5 is housed here entirely in the through opening.20a.
The room has a part housing the diode. The walls 53 of the entourage comprise two or more four internal pins 55a holding the diode by its edge.
The functional zone of the textured face is in front of the front surface 40. The peripheral zone in front of the front surface 42 'of the envelope 42 may or may not be textured or even used to create an air gap between the patterns and the F3 face.

Figure c shows a view from behind (front side F2) of this carrier part of the collimation optics, here a network of hollow pyramids.

FIG. 1d shows a partial diagrammatic sectional detail view of the laminated glazed roof according to an embodiment of the invention which differs from FIG. 1a by bonding the part 5 to the front surface of the envelope (rather than or in addition to the one on the support 3).
Alternatively it may be a force fit on the diode (the envelope), the peripheral extension may be spaced from the support 3.

(layer etc) isolated 18 'on the face F3 (deletion of the diode support and the PVB back sheet).)
FIG. 1 shows a partial diagrammatic sectional detail view of the laminated glazed roof according to an embodiment of the invention which differs from FIG. 1a by the deletion of the PVB backsheet replaced by an adhesive. and especially the fact that the PVB sheet 21 has a blind hole (with a single sheet or two sheets, one with through openings) rather than a through opening forcing to isolate the outlet face of the PVB bottom by a piece (double bottom ) stuck to the optical part 5
As shown in Figure i concerning the manufacture of the roof, the angled PCB thus has a first portion (rectangular) 31 carrying diodes 4 (and with the elbow) and a second portion 32 for the connector (rectangular), for example two copper tracks 33 with an insulation line 34 opening and protruding on the edge of the roof. This second part can be (much) longer than the first part.
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.
