Description

Lighting glazing
The present invention relates to a glazing assembly having a light source.
Motor vehicles have a light distribution in the interior space that provides unobtrusive or attractive illumination of the interior space as desired. The illumination is not only responsible for directing the light in the vehicle, but also creates a pleasant atmosphere for the occupants. Composite glass sheets made of two or more glass sheets of a vitreous or polymeric substance as glazing are used in vehicles as windshields, rear glazings, side glazings and sunroof glasses. In the case of illuminable or illuminated glazing, total reflection is used to couple the light of the light source into a planar light conductor in the form of a glazing glass plate.
WO 2010/049638 A1, WO 2013/053629 A1, WO 2014060409 A1 or WO 2015/095288 A2 disclose coupling light into a vitreous glass plate via a side. If the light source is placed very close to the glass edge, light can in this way be coupled into the light guide very efficiently and over the entire width of the light guide. A very uniform planar illumination can thus be achieved. It is known from WO2013/110885 A1, WO2018178591 A1 or WO2019/105855A1 to arrange light sources into recesses and thereby couple light into a glass plate. The grooves are typically disposed in one of the two vitreous glass plates of the composite glass plate and are hidden by opaque printing when the other of the two vitreous glass plates is viewed. Depending on the hiding power of this print, the light source is visible when another vitreous glass plate is viewed, and a slightly brighter light ring appears around the location where light is coupled into the glass plate. This should be avoided for aesthetic reasons.
DE 10201102092996 A1 discloses a glass plate assembly with a lighting device. The lighting device is attached to a glass plate body and includes a light source and a light conductor layer disposed on the glass plate body.
A glazing having LEDs arranged in recesses is known from WO 2018/178591 A1. The glazing includes a photoconductor element.
It is an object of the present invention to provide an improved glazing assembly having high efficiency and increased reliability.
The object is achieved by a glazing assembly according to claim 1. Preferred embodiments are evident from the dependent claims.
A glazing assembly according to the invention includes a first glass sheet having a first major surface and a second major surface. The first glass plate is connected with the second glass plate through an interlayer to form a composite glass plate. In this case, a first glass plate is provided for at least partially further conducting the light that is coupled in. Furthermore, the glazing assembly includes a light source for generating light that is coupleable into the first glass sheet, the light source being disposed in the recess of the first glass sheet. Furthermore, the glazing assembly comprises a cover of the recess and a filler material permeable to optical radiation of the light source in the recess.
The filler material is used to embed the light source in the recess. The light emitted from the light source is thus improved in-coupling into the first glass plate. The glazing assembly according to the invention achieves high efficiency and increased reliability because the light generated from the light source is directed into the first glass sheet.
Preferably, the filling material is provided from a hard, soft, deformable, gel-like and/or liquid material. In particular, the recess can be filled in a form-fitting manner with a deformable material, so that no disturbing scattered light escapes. The filler material may comprise, for example, a silica gel or a resin, in particular a synthetic resin.
Here, the filling material in the recess may have a refractive index of 1.45 to 1.55. The refractive index of the filler material is selected such that total reflection at the interface of the filler material and the first glass plate is avoided. In particular, the refractive index n of the filler material is chosen F And refractive index n of the first glass plate S Thereby being applicable to n F ≤n S . Particularly advantageously, the filler material has a refractive index similar to glass.
Within the scope of the present invention, the refractive index is in principle given on the basis of a wavelength of 550 nm. In principle, the refractive index is independent of the measurement method; it can be determined, for example, by means of ellipsometry. Ellipsometers are commercially available. In determining the refractive index of the filler material, the same measurement method as in determining the refractive index of the first glass plate is used.
In a particularly preferred embodiment, the filler material is transparent. This allows particularly efficient coupling of light into the first glass plate.
In one embodiment of the invention, the filler material is additionally arranged around the recess on the first main surface of the first glass pane. For example, the filling material can here protrude about 2mm to 50mm, preferably 5mm to 30mm.
In an advantageous embodiment of the glazing assembly according to the invention, the light source comprises at least one light emitting diode (LED, english light emitting diode), preferably at least one organic light emitting diode (OLED, english organic light emitting diode), and/or at least one laser diode.
In a particularly preferred embodiment, the glazing assembly additionally has a light conductor in the recess. The light guide is provided for conducting light such that light generated by the light source enters the first glass plate. The light source and the light conductor may be formed as a structural unit, in particular as a module. In this case, the structural unit may have an LED circuit board including one or more LEDs. In addition, the LED circuit board may be formed as a Printed Circuit Board (PCB). Preferably, the light source has a plurality of LEDs. This type of light source is particularly bright and efficient. The structural unit may be detachably arranged on the first glass plate. The reversibly closed opening of the recess into the (vehicle) interior space is also advantageous for maintenance work of the structural unit. In this embodiment, a filler material is used to embed the light conductor and the light source in the recess. The light emitted from the light source is thus improved in-coupling into the first glass plate. The glazing assembly achieves high efficiency and increased reliability because the generated light emitted from the light guide is directed into the first glass sheet.
According to an embodiment variant, the particularly reflective cover may be disc-shaped, preferably formed from aluminum. For example, the cover may be reflective and have a highly reflective layer on the side facing the recess. Preferably, a cover is arranged on the second main surface (III) of the first glass plate, wherein the reflective cover completely covers the recess. Preferably, the cover may be arranged around the recess. In this case, the cover may protrude about 2mm to 50mm, preferably 5mm to 30mm.
The cover prevents moisture or components of the intermediate layer from possibly diffusing into the recess. The cover is preferably embodied as a metal foil or a metallized plastic film. The metal foil reflects well and can efficiently turn light emitted in the light source region back into the first glass plate. The metal foil is preferably aluminum foil. It goes without saying that foils/films or layers of this type can also be arranged on carrier films, for example polymeric carrier films such as polyimide or polyethylene terephthalate (PET).
The cover is preferably directly attached to the second major surface of the first glass sheet. It may be attached to the second major surface of the first glass sheet, for example, by an adhesive layer. The cover is preferably also adapted to inhibit light emitted from the first glass plate from entering into the first glass plate or to divert it back into the first glass plate by reflection, preferably directional reflection, scattering, preferably diffuse scattering or diffraction.
In a particularly preferred embodiment, a shielding element for shielding the light source is arranged between the reflective cover and the second glass pane. In the installed position of the glazing assembly, the shielding element shields the light source from the external environment. In this case, the shielding element completely covers the reflective cover. The shielding element is arranged in the region of the light source, that is to say, when viewed through the composite glass pane, it overlaps the recess in which the light conductor is arranged with the light source. The shielding element is thus arranged in a locally limited region, that is to say not over the entire surface of the composite glass pane. Furthermore, the cover may be arranged around the recess (on all sides) and in this case protrude about 2mm to 50mm, preferably 5mm to 30mm. In other words, the cover may have a larger cross-sectional area than the recess and/or the cover. This has the advantage that no light is emitted from the recess in the direction of the second glass plate and that the recess is particularly dense and stably shielded.
The shielding element may comprise an opaque, preferably black, polyethylene (PET) film or a polyvinyl butyral (PVB) film. Opaque in the sense of the present invention means that the viewer cannot see through the film, intermediate layer or cover layer. The interlayer is preferably made of PVB. Thus, shielding elements made of PVB can be integrated particularly well into interlayers made of PVB. PET can be readily processed into colored films because it is compatible with common interlayer materials. The intermediate layer and the shielding element preferably have the same thickness.
The recess and the opaque shielding element may have any geometrical shape, independently of each other, such as a circular, quadrangular, triangular, square, rectangular, pentagonal or other regular or irregular polygonal shape.
In an advantageous embodiment of the glazing assembly according to the invention, the opaque coating is arranged on the second main surface (II) of the second glass pane in the circumferential edge region. The cover layer can extend from the glass pane edge of the second glass pane beyond 1mm to 500mm, preferably 10mm to 150mm, particularly preferably 10mm to 15mm. In particular, the cover layer and the recess overlap at least partially in the perspective direction of the composite glass sheet.
The overlay is also referred to as overlay print or black print. The overlay print is formed from ink. The cover layer may be formed of an opaque enamel, preferably applied as screen printing or digital printing. The enamel may comprise a vitreous frit and/or a mineral frit and optionally at least one pigment, preferably the vitreous frit and/or the mineral frit is based on an oxide selected from boron, bismuth, zinc, silicon, aluminum and sodium. The pigment provides the opacity of the cover layer. The pigment may be a black pigment, such as pigment black (carbon black), aniline black, bone black, iron oxide black, spinel black, and/or graphite. Alternatively, the cover layer may be formed as a particularly black tape or as a substrate layer, a so-called primer. The composite glass sheet can have a plurality of cover layers. The cover layer may have a layer thickness of 5 μm to 50 μm, particularly preferably 8 μm to 25 μm.
The composite glass sheet has a see-through region in which the composite glass sheet is free of a cover layer. The see-through area of the composite glass sheet comprises at least 30%, preferably 50% of the area of the composite glass sheet. If the composite glass sheet is formed into a sunroof glass or a windshield, the see-through region may comprise at least 70% or at least 80% of the area of the composite glass sheet.
In principle, all electrically insulating substrates that are thermally and chemically stable as well as dimensionally stable under the conditions of manufacture and use of the composite glass sheet are suitable as first glass sheet and second glass sheet.
The first glass pane and the second glass pane preferably comprise glass, particularly preferably float glass made of transparent glass, very particularly preferably diamond glass. Alternatively, the glass sheet may also comprise a flat glass, such as soda lime glass, borosilicate glass or quartz glass, or a transparent plastic, a rigid transparent plastic, in particular polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polyamide, polyester, polyvinylchloride and/or mixtures thereof. The first glass pane and/or the second glass pane is preferably transparent, in particular for use of the glass pane as a sunroof, windscreen or rear window of a vehicle or for other applications requiring high light transmittance. In particular, at least the first glass pane and preferably also the second glass pane is composed of transparent glass.
A coating, in particular a glass plate or object, is understood to be transparent if it has a transmittance in the visible spectral range of more than 20%, preferably 50%, particularly preferably more than 70%, in particular more than 85%.
However, the transmission may also be much lower, for example greater than 5%, for glass sheets that are not in the view of traffic-related drivers, for example for sunroof glass. For this purpose, for example, the second glass plate and/or the intermediate layer may be tinted or colored.
The thickness of the first and second glass plates can vary widely and thus be adapted to the individual requirements excellently. A standard thickness of 1.0mm to 25mm, preferably 1.4mm to 2.5mm, is preferably used for vehicle glass and a standard thickness of 4mm to 25mm is preferably used for furniture, appliances and buildings. The dimensions of the glass plate can vary widely and depend on the dimensions of the use according to the invention. For example, in the field of vehicle construction and architecture, the area of the first and second glass sheets is typically 200cm2 to 20m2.
The composite glass sheet can have any three-dimensional shape. The three-dimensional shape is preferably free of shadow areas so that it can be coated with a further coating, for example by sputtering. Preferably, the glass sheet is planar or slightly or strongly curved in one or more spatial directions. In particular, a planar substrate is used. The glass sheet may be colorless or colored.
The first glass sheet and the second glass sheet are connected to each other by at least an interlayer. The intermediate layer is preferably transparent or coloured. The intermediate layer preferably comprises or consists of at least one plastic, preferably polyvinyl butyral (PVB), ethylene Vinyl Acetate (EVA) and/or polyethylene terephthalate (PET). However, the intermediate layer may also comprise, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resin, acrylate, fluorinated ethylene-propylene, polyvinyl fluoride and/or ethylene-tetrafluoroethylene, or copolymers or mixtures thereof. The intermediate layer may be formed of one or more films arranged one above the other, wherein one film preferably has a thickness of 0.025mm to 1mm, typically 0.38mm or 0.76mm. The intermediate layer may preferably be thermoplastic and the first glass plate, the second glass plate and possibly further intermediate layers are bonded to each other after lamination. A so-called acoustically damping interlayer, preferably consisting of three PVB plies, is particularly advantageous, wherein the interlayer ply is formed softer than the two outer plies.
The intermediate layer may also have a functional layer, in particular an infrared radiation reflecting layer, an infrared radiation absorbing layer, a UV radiation absorbing layer, an at least partially coloured layer and/or an at least partially coloured layer. Thus, the thermoplastic intermediate layer may also be, for example, a belt filter.
The terms "first glass sheet" and "second glass sheet" are chosen to distinguish between two glass sheets in a composite glass sheet according to the invention. No statement regarding geometric arrangement is associated with these terms. For example, if a composite glass sheet according to the invention is provided for separating an interior space from an external environment in an opening of, for example, a vehicle or building, the first glass sheet may face the interior space or the external environment.
In an advantageous embodiment of the glazing according to the invention, the light out-coupling means can be arranged on/in at least one main surface of the first glass pane, preferably on/in the second main surface. The light coupled into the first glass pane is then coupled out of the first glass pane via a light coupling-out means and thus lightens the first glass pane there. The light out-coupling means are adapted to couple out the light, which is partly conducted in the first glass plate, out of at least one main surface of the first glass plate, preferably by scattering, reflection, refraction or diffraction.
The light out-coupling means are advantageously arranged or introduced into the first main surface and/or into the second main surface and/or into the first glass pane.
For this purpose, light out-coupling measures are introduced into the first main surface and/or the second main surface, preferably by laser structuring, mechanical structuring such as sand blasting and/or by etching.
Alternatively or in combination, the light out-coupling means can be connected to the first main surface and/or the second main surface of the first glass plate in a material-locking manner, preferably by printing or gluing with inks, pastes or particles, particularly preferably particles that scatter, refract or reflect light.
Alternatively or in combination, the light out-coupling means may comprise or consist of particles, particularly preferably particles or cavities that scatter, refract, diffract or reflect light, arranged in the first glass plate.
In an advantageous embodiment, the composite glass pane is a sunroof glass of a motor vehicle and the first glass pane is an inner glass pane and the second glass pane is an outer glass pane. Technical advantages are thereby achieved, for example, that the glazing assembly is used in a particularly suitable location.
Furthermore, the first glass sheet and/or the second glass sheet may have additional suitable coatings, such as anti-reflective coatings, release coatings, scratch-resistant coatings, photocatalytic coatings, sun-protection coatings, and/or low-E coatings.
In a preferred embodiment, the second glass sheet has a transparent functional coating comprising a conductive layer on its second major surface. The transparent functional coating is preferably a sun protection coating. The sun protection coating reflects solar radiation components in the near infrared spectrum and prevents them from entering the vehicle interior space and heating it. They generally have one or more silver layers which provide infrared reflection properties, as is known, for example, from WO2013/104439A1 and DE 19927683C 1. Thus, these layers are arranged on the side of the second glass plate facing the thermoplastic interlayer to protect them from corrosion and mechanical damage.
In a preferred embodiment, the first glass sheet has a low E coating on its first major surface. A low E coating is a coating that reduces emissivity and reflects IR radiation, especially thermal radiation emitted by a heated vitreous glass sheet. The radiation of heat into the interior space of the vehicle is reduced, which likewise results in a reduced heating of the interior space. In winter, when the outdoor temperature is low, heat of the inner space is prevented from being emitted into the external environment. The transparent emissivity-reducing coating may comprise a reflective layer, for example based on Indium Tin Oxide (ITO) or other Transparent Conductive Oxide (TCO), as is known for example from WO2013/131667 A1. When implemented as sunroof glass, they ensure reflection of heat radiation into the interior space of the vehicle, which significantly increases the comfort of the vehicle occupants. The low E coating preferably does not comprise a silver layer and thus can be disposed on the first major surface of the first glass sheet without corrosion problems.
In a preferred embodiment of the glazing assembly according to the invention, a functional coating having a conductive layer, in particular a silver layer, is arranged on the second major surface of the second glass sheet. On this functional coating, an opaque overlay print is arranged in the edge region. That is, the opaque overlay print is printed directly onto the functional coating. The covering print is preferably formed here from a printing ink which has functional coating decomposition properties. In this case, the advantages of the invention are particularly pronounced, since the cover print formed in this way in the open state often does not adequately cover the light source. An additional measure, namely the shielding element according to the invention, is an excellent solution here.
Furthermore, the glazing assembly can optionally include additional functional elements, particularly electronically controllable optical elements, such as PDLC elements, electrochromic elements, or the like, which are typically disposed between the first and second glass sheets.
Another aspect of the invention includes a glazing assembly according to the invention that includes a voltage source and control electronics connected to the light source. The light source may be controlled by a voltage source and control electronics so that it emits light when a voltage is applied to the light source.
In another aspect, the invention includes a vehicle, particularly a passenger car, having a glazing assembly according to the invention.
In another aspect, the invention includes a method for manufacturing a glazing assembly according to the invention, comprising at least:
providing a first glass pane, a second glass pane and in particular a thermoplastic interlayer,
creating at least one recess in the first glass sheet,
the cover is arranged on the recess and,
joining the first glass pane and the second glass pane via the thermoplastic interlayer such that the second main surface (III) of the first glass pane faces the thermoplastic interlayer,
filling the recess with a filling material permeable to light radiation,
at least one light source is arranged in the recess.
The first glass sheet and the second glass sheet are laminated to each other via an interlayer, for example, by an autoclave process, a vacuum bag process, a vacuum ring process, a calendaring process, a vacuum laminator, or a combination thereof. The glass panes are generally connected here under the effect of heat, vacuum and/or pressure.
The recess may be created by various methods known to those skilled in the art for drilling or cutting glass.
Preferably, the first glass plate and the second glass plate comprise glass. In this case, the recess is introduced into the glass pane by means of a laser method. This is particularly advantageous because the laser method can be performed without a mechanical processing step, for example crushing by mechanical pressure. The vitreous glass plate is thus cut in a gentle manner, so that a smooth cut edge is formed without disturbing damage. Machining by means of laser methods is particularly useful in particular when thin vitreous glass plates (thickness less than or equal to 1.4 mm) are used.
The thermoplastic intermediate layer is preferably provided as a film.
In a particularly preferred embodiment of the method, the light conductor is arranged in the recess together with the light source. The light source and the light conductor may be formed as a structural unit, in particular as a module. In this case, the structural unit may have an LED circuit board including one or more LEDs.
Furthermore, the invention includes the use of a glazing assembly according to the invention in a vehicle for land, air or water traffic, in particular in a motor vehicle, for example as a sunroof, rear window and/or side window.
All embodiments mentioned for the individual features can also be freely combined with one another within the scope of the invention, provided that they do not contradict one another.
The invention is explained in more detail below with reference to the drawings and the exemplary embodiments. The figures are schematic representations and are not drawn to scale. The drawings are not intended to limit the invention in any way.

Data having numerical values should not generally be construed as exact values, but rather also include tolerances of +/-1% to +/-10%.
Fig. 1 shows a top view of one embodiment of a composite glass sheet 10 according to the present invention. Glazing assembly 10 includes a composite glass sheet 101 and at least one structural unit 5. Glazing assembly 10 may be, for example, a sunroof glass for a vehicle. Alternatively, glazing assembly 10 may be a component of a building glazing or a piece of furniture or electrical equipment. Glazing assembly 10 may also be part of insulating glass and be used, for example, as an outer or inner glass pane in a building window. Furthermore, the glazing assembly 10 may be installed in an interior space and may be used, for example, as a glazing for a conference room.
Glazing assembly 10 comprises a composite glass sheet 101 and two structural units 5 each having one light source 5.1. A light source 5.1 is provided for emitting light in the visible range. Alternatively, they may emit infrared or ultraviolet light.
The composite glass sheet 101 also has four light out-coupling measures 11. The light out-coupling means 11 causes light out-coupling from the composite glass sheet 101. The light out-coupling means 11 is arranged on the first main surface (IV) of the composite glass sheet 101. At the location where the light out-coupling means 11 are arranged, light can be emitted from the composite glass sheet 101 via the main surface (IV).
The light out-coupling means 11 may be arranged at any position on the first main surface (IV). In fig. 1, the light out-coupling means 1 comprises a structuring of the main surface IV, where total reflection within the composite glass sheet 101 and light emission from the composite glass sheet 101 via the main surface (IV) are prevented. The light out-coupling means 11 may comprise printed matter on the first main surface (IV) or particles or cavities of scattered, refracted, diffracted or reflected light introduced into the composite glass sheet 101.
In the present exemplary embodiment, the light out-coupling means 11 are formed here as a print of fine light-scattering particles on the main surface (IV). By which the total reflection of the light beam at the interface between the composite glass sheet 101 and the surrounding air is interrupted and light is coupled out of the composite glass sheet 101 by scattering.
The composite glass sheet 101 has a see-through region 15 and an edge region 16. The cover layer 4 is arranged in the edge region 16. Composite glass sheet 101 also includes a surrounding glass sheet edge 17. The cover layer 4 extends here around the entire circumferential glass pane edge 17. In this embodiment, the cover layer 4 extends in a frame-like manner in the edge region 16 of the composite glass pane 101. The cover layer 16 frames the see-through region 12.
Alternatively, the cover layer 4 can be arranged at least partially along the circumferential glass pane edge 12. The width of the edge region 16 may vary. In this embodiment, the width of the edge region 16 is measured from the glass pane edge 12 and is, for example, 10mm, 50mm or 100mm.
The composite glass sheet 101 has a see-through region 15, wherein the composite glass sheet 101 is free of a cover layer. The see-through region 15 of the composite glass sheet 101 comprises at least 70% of the surface area of the composite glass sheet.
Fig. 2 shows a cross-sectional view of the glazing assembly 10 of fig. 1 according to the invention. The composite glass sheet 101 comprises a first glass sheet 1 joined to a second glass sheet 2 by an interlayer 3. The first glass plate 1, the intermediate layer 3 and the second glass plate 6 are connected to each other by lamination, in particular in an autoclave. The first glass sheet 1 has a first major surface IV and a second major surface III opposite the first major surface IV. The second glass sheet 2 has a first major surface I and a second major surface II opposite the first major surface I.
The sides of the composite glass sheet 101 are disposed orthogonally to the major surfaces III, IV. The first glass plate 1 and the second glass plate 2 are made of soda lime glass, for example. The interlayer 3 is thermoplastic and is formed, for example, from a 0.76mm thick PVB film. The thickness of the first glass plate 1 is, for example, 1.6mm, and the thickness of the second glass plate 2 is, for example, 2.1mm. However, the first glass plate 1 and the second glass plate 2 may also have any thickness, for example the same thickness. The composite glass sheet 101 is defined by four surrounding sides.
The first glass plate 1 may have a pre-stressed, partially pre-stressed or non-pre-stressed glass. Alternatively, the first glass plate 1 may be composed of plastic, for example, of polycarbonate. For example, the first glass plate 1, the second glass plate 2, and the intermediate layer 3 are colorless and transparent (neither colored nor colored). Alternatively, the interlayer 3 may have a colored, in particular dark-colored (grey, brown, blue) or colored PVB film. Alternatively or additionally, the second glass plate 2 may be dark (grey, brown, blue) coloured.
The first glass pane 1 has a recess 9, into which recess 9 the structural unit 5 protrudes. The recess 9 extends continuously from the first main surface IV of the first glass plate 1 up to the second main surface III of the first glass plate 1. In order to seal the recess 9 (in the mounted position of the composite glass pane), a cover 6 in the form of an aluminum foil or an aluminum disc is fixed to the recess at the second main surface III of the first glass pane 1 by means of an adhesive tape. In addition to improving the long-term stability by preventing, for example, moisture diffusion, the cover 6, due to its good reflective properties, in turn, converts the light of the light source 5.1 back into the first glass plate 1, thus increasing the total amount of light that is coupled in.
The structural unit 5 comprises a light source 5.1 and a light conductor 5.2. The structural unit 5 may be a so-called LED module. The intermediate layer 3 is not removed in the region of the recess 9. The light source 5.1 is located entirely within the composite glass sheet 101. The light source 5.1 is preferably an LED. The light source 5.1 may comprise one or more light emitting diodes (LEDs, LED lighting fixtures). The light source 5.1 may also comprise an Organic Light Emitting Diode (OLED).
The light emitted by the light source 5.1 is directed towards the glass plate 1 and reaches the first glass plate 1 via the light conductor 5.2. Light emitted from the light source 5.1 is coupled into the first glass plate 1 and propagates away in the first glass plate 1. The glass plate 1 is provided for further conducting the light coupled in the longitudinal direction through the glass plate 1.
The first glass pane 1 is preferably an inner glass pane and the second glass pane 2 is an outer glass pane. In the installed position, the inner glass panel faces the interior space. In the installed position, the outer glass pane faces the external environment (e.g., of a vehicle). This arrangement is particularly advantageous because of the position of the light source 5.1 in the first glass pane 1, since the light is coupled out in the direction of the (vehicle) interior space, which creates a pleasant atmosphere in the interior space. Alternatively, the second glass plate 2 may be an inner glass plate and the first glass plate 1 an outer glass plate.
The first cover layer 4 and the second cover layer 4 are applied on the first main surface IV of the first glass plate 1 and on the second main surface II of the second glass plate 2. The cover layer 4 is of a dark colour (blickdicht), in particular black or grey, which obscures the view. The cover layer 4 is formed of printing ink. Since it is not desirable for light to be coupled out at the edges of the composite glass sheet 101, the edge region 16 of the first glass sheet 1 has a cover layer 4.
Furthermore, a dark, in particular black or gray-black, second cover layer 4, which obstructs the view, is arranged on the second main surface II of the second glass pane 2. In particular, the first cover layer 4 and the second cover layer 4 overlap in the perspective direction of the composite glass sheet 101. The recess 9 is covered in perspective by the second cover layer 4. The first and second cover layers 4 are circumferential, i.e. frame-like, cover prints. The cover layer 4 may be formed to block the view, opaque, and/or fully.
The first cover layer 4 and the second cover layer 4 contain pigment and vitreous frit. They may contain other chemical compounds. The vitreous frit can melt or fuse and the cover layer 4 can thus be permanently connected (fused or sintered) to the glass surface. The pigment ensures the opacity of the cover layer 4. Such a coating is applied as an enamel. Alternatively, the first cover layer 4 and/or the second cover layer 4 may be formed as an adhesive tape, a color layer, or a primer. The tape, color layer and primer are preferably black.
Fig. 3 shows a schematic cross-sectional view of a second embodiment of a glazing assembly 10 according to the invention. The glazing assembly 10 shown in fig. 3 is particularly well suited as a sunroof glass for a motor vehicle. The glazing assembly 10 of fig. 3 has a structure similar to the glazing assembly 10 of fig. 2. The second glass plate 6 (outer glass plate) is identical to the glass plate 6 of fig. 2. Unlike fig. 2, the recess 9 has a filler material 7. The filling material 7 serves to embed the light conductor 5.2 and the light source 5.1 in the recess 9. The light emitted from the light source 5.1 is thus improved in-coupling into the first glass plate 1. The glazing assembly 10 thus achieves high efficiency and increased reliability, since the light generated that emerges from the light guide 5.2 is directed into the first glass pane 1.
The filler material 7 is formed of a deformable material. The filler material 7 is transparent. The transparent filling material 7 fills the recess in a form-locking manner. The filler material 7 may comprise, for example, a silicone gel or a resin, in particular a synthetic resin. Furthermore, a filler material 7 is arranged around the recess 9 on the first main surface IV of the first glass plate 1. For example, the filling material may protrude here by about 10mm or 15mm.
The refractive index of the filler material 7 was 1.50. The refractive index of the filler material is the same as that of the first glass plate 1. The refractive index of the filler material 7 is chosen such that total reflection at the interface of the light guide 5.2 and the first glass plate 1 is avoided.
Fig. 4 shows a schematic cross-sectional view of another embodiment of a glazing assembly 10 according to the invention. The glazing assembly 10 shown in fig. 4 is particularly well suited for use as a sunroof glass for a motor vehicle. The glazing assembly 10 of fig. 4 has a similar structure to the glazing assembly 10 of fig. 3. Unlike fig. 3, the composite glass sheet 101 includes a shielding element 8. A shielding element 8 is arranged at the reflective cover 6. In the installed position of the glazing assembly 10 as a sunroof glass of a vehicle, the shielding element 8 is arranged on the cover 6. The shielding element 8 protrudes around the recess 9 by a distance of 3mm as shown.
The shielding element 8 is embodied as a black PVB film, which is inserted between two 0.38mm thick PVB sublayers 3.1 and 3.2 of the thermoplastic interlayer 3. The shielding element 8 is based on the same material as the thermoplastic intermediate layer 3. This prevents material incompatibility and possible different dimensional changes of the film and intermediate layer used after lamination. Thanks to the shielding element 8 arranged according to the invention, the occurrence of low light (lichtschemmer) in the region of the light source 5.1 is also prevented in this case. The cover 6 is arranged below the shielding element 8 and is directly fixed to the second main surface III of the first glass pane 1.
Fig. 5 shows a schematic cross-sectional view of another embodiment of a glazing assembly 10 according to the invention. The glazing assembly 10 shown in fig. 5 is particularly well suited for use as a sunroof glass for a motor vehicle. The glazing assembly 10 of fig. 5 is similar in structure to the glazing assembly 10 of fig. 4.
The shielding element 8 is embodied as a black PVB film inserted in an interlayer 3 of 0.76mm thickness. The shielding element 8 is based on the same material as the thermoplastic intermediate layer 3. This prevents material incompatibility and possible different dimensional changes of the film and intermediate layer used after lamination. Thanks to the shielding element 8 arranged according to the invention, the occurrence of low light in the region of the light source 5.1 is also prevented in this case. The cover 6 is arranged below the shielding element 8 and is directly fixed to the second main surface III of the first glass pane 1.
