Definitions

  • the invention relates to a glazing arrangement with a light source and a light extraction means, a method for their production and their use.
  • Motor vehicles have a light distribution in the interior, which provides for a discreet or conspicuous illumination of the interior, depending on requirements.
  • the lighting not only provides orientation in the vehicle, but also creates a pleasant atmosphere for the occupants.
  • Composite panes as glazing made from two or more glass or polymer panes are used in vehicles as windshields, rear windows, side windows and roof windows.
  • light from a light source is coupled into a flat light guide in the form of a pane of the glazing using total reflection.
  • WO 2010/049638 A1, WO 2013/053629 A1, WO 2014060409 A1 or WO 2015/095288 A2 disclose the coupling of light into a glass pane via a side surface. If the light source is placed very close to the edge of the glass, light can be coupled into the light guide very efficiently and over the entire width of the light guide. As a result, a very homogeneous, planar illumination can be achieved. It is known from WO2013/110885 A1, WO2018178591 A1 or 2019/105855 A1 to arrange the light source in a recess and thereby couple the light into the pane.
  • WO 2020/201973 A1 discloses a method for producing an illuminated and curved composite pane for motor vehicles with a light-conducting glass layer.
  • the light reflections reach the edge area of the pane as a result of multiple reflections on the parallel surfaces of the pane, where they can emerge from the pane again. This creates a lighted edge area. This undesired light effect in the edge area of the pane can easily be perceived by an observer.
  • the object of the present invention is to provide an improved glazing arrangement in which light coupled into the pane cannot be perceived as scattered light in the edge area of the sliding panel. This object is solved by a glazing arrangement according to claim 1 . Preferred embodiments emerge from the dependent claims.
  • the glazing arrangement comprises at least a first pane, a light source for generating light that can be coupled into the first pane, and a light output coupling means for coupling light out of the first pane, the first pane being provided to at least partially forward coupled light.
  • the first disc has at least a first surface (IV) and a second surface (III).
  • the light outcoupling means are provided for outcoupling the light via one of the two surfaces (III, IV).
  • the first pane is connected to a second pane via an intermediate layer to form a composite pane.
  • the glazing arrangement also comprises an edge region, which extends from a pane edge of the first pane over at least 1 mm to at most 500 mm on one of the surfaces (III, IV) of the first pane, as well as an absorption means for absorbing light coupled into the first pane, which is arranged in the edge area.
  • the absorbent is designed as a first covering layer which is arranged on the intermediate layer.
  • the absorbent may comprise a second cover layer arranged on the first surface (IV) of the first pane. Since it is not desirable for light to be coupled out at the edges of the composite pane, the edge area of the first pane has the cover layers, which absorb the scattered light. This prevents the scattered light in the edge area of the laminated pane with little effort.
  • the first covering layer and the second covering layer can extend from the pane edge of the first pane over 1 mm to 500 mm, preferably 10 mm to 150 mm, particularly preferably 10 mm to 15 mm.
  • the second covering layer is arranged on the first surface (IV) of the first panes.
  • the second pane has a third cover layer.
  • the first covering layer, the second covering layer and the third covering layer can at least partially overlap in the viewing direction of the laminated pane. In this way, the scattered light in the edge area on the two main sides of the laminated pane is absorbed particularly effectively.
  • the first covering layer, the second covering layer and/or the third covering layer are opaque, in particular opaque.
  • the cover layers are also referred to as cover print or black print.
  • the masking print is formed from one ink.
  • the first cover layer is a printed opaque layer.
  • the printed opaque layer can be an opaque layer which is applied to the intermediate layer by means of a printing process. In particular, the printed opaque layer is black.
  • the second cover layer and/or the third cover layer can be formed from an opaque enamel, preferably applied as a screen print or as a digital print.
  • the enamel can contain glass frits and/or mineral frits and optionally at least one pigment, preferably glass frits and/or mineral frits based on oxides selected from boron, bismuth, zinc, silicon, aluminum and sodium.
  • the pigment provides the opacity of the cover layer.
  • the pigment can include a black pigment, for example carbon black, aniline black, bone black, iron oxide black, spinel black and/or graphite.
  • the first, second and/or third cover layer can be formed as an in particular black adhesive tape or a base layer, a so-called primer.
  • the primer may comprise a sol-gel layer of silicon oxide mixed with other inorganic oxides.
  • the first covering layer, the second covering layer and the third covering layer can be designed over the whole area and/or in the manner of a frame.
  • the laminated pane comprises a peripheral pane edge, the absorbent being arranged at least in sections along the peripheral pane edge or the absorbent extending peripherally along the entire peripheral pane edge.
  • the laminated pane has a see-through area in which the laminated pane has no cover layer.
  • the see-through area of the laminated pane makes up at least 30%, preferably 50%, of the area of the laminated pane. If the composite pane is designed as a roof pane or windshield, the see-through area can make up at least 70% or at least 80% of the area of the composite pane.
  • the light source can include one or more light-emitting diodes (LED, LED module, LED lamp). This type of light source is particularly bright and effective.
  • the first pane has at least one recess for receiving the light source. As a result, a reduction in the light scattered into the environment outside of the laminated pane and improved coupling of light into the first pane can be achieved.
  • the light source can be outside of the laminated pane on a side surface or on the first surfaces (IV) of the first pane, so that light is coupled into the first pane via an outer side surface or the first surface (IV).
  • the first pane and the second pane preferably contain glass, particularly preferably float glass made from clear glass, very particularly preferably diamond glass.
  • the panes can also contain flat glass such as soda-lime glass, borosilicate glass or quartz glass, or clear plastics, rigid clear plastics, in particular polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polyamide, polyester, polyvinyl chloride and/or mixtures thereof.
  • the first pane and/or second pane are preferably transparent, in particular for use of the panes as roof panes, windshields or rear panes of a vehicle or other uses where high light transmission is desired.
  • at least the first pane and preferably also the second pane are made of clear glass.
  • a coating in particular a pane or an object, is understood to be transparent if the coating, pane or object has a transmission in the visible spectral range of greater than 20%, preferably 50%, particularly preferably greater than 70%, in particular greater than 85% .
  • the transmission can also be much lower, for example greater than 5%.
  • the second pane and/or the intermediate layer can be tinted or colored.
  • the thickness of the first pane and/or second pane can vary widely and can thus be perfectly adapted to the requirements of the individual case. Standard thicknesses of 1.0 mm to 25 mm, preferably 1.4 mm to 2.5 mm for vehicle glass and preferably 4 mm to 25 mm for furniture, appliances and buildings are preferably used.
  • the size of the discs can vary widely and depends on the size of the use according to the invention.
  • the first pane and second pane have areas of 200 cm 2 up to 20 m 2 , which are common in vehicle construction and architecture, for example.
  • the composite pane can have any three-dimensional shape.
  • the three-dimensional shape preferably has no shadow zones, so that it can be coated with further coatings, for example by sputtering.
  • the discs are planar or light or strong in one or more directions of the space curved. In particular, planar substrates are used.
  • the discs can be colorless or colored.
  • the first pane and the second pane are connected to one another by at least the intermediate layer.
  • the intermediate layer is preferably transparent or tinted or colored.
  • the intermediate layer preferably contains or consists of at least one plastic, preferably polyvinyl butyral (PVB), ethylene vinyl acetate (EVA) and/or polyethylene terephthalate (PET).
  • the intermediate layer can also be, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resins, acrylates, fluorinated ethylene-propylene, polyvinyl fluoride and/or ethylene-tetrafluoroethylene , or contain copolymers or mixtures thereof.
  • the intermediate layer can be formed by one film or by a plurality of films arranged one on top of the other, the thickness of a film preferably being from 0.025 mm to 1 mm, typically 0.38 mm or 0.76 mm.
  • the intermediate layers can preferably be thermoplastic and, after lamination, can bond the first pane, the second pane and any further intermediate layers to one another.
  • So-called acoustic-damping intermediate layers which preferably consist of three layers of PVB, are particularly advantageous, with the middle layer being softer than the two outer layers.
  • the intermediate layer can also have a functional layer, in particular a layer that reflects infrared radiation, a layer that absorbs infrared radiation, a layer that absorbs UV radiation, a layer that is colored at least in sections and/or a layer that is tinted at least in sections.
  • a functional layer in particular a layer that reflects infrared radiation, a layer that absorbs infrared radiation, a layer that absorbs UV radiation, a layer that is colored at least in sections and/or a layer that is tinted at least in sections.
  • the thermoplastic intermediate layer can also be a belt filter.
  • first pane and second pane are chosen to distinguish between the two panes in a composite pane according to the invention.

Description

Beleuchtbare Verglasung Illuminatable glazing
Die Erfindung betrifft eine Verglasungsanordnung mit einer Lichtquelle und einem Lichtauskopplungsmittel, ein Verfahren zu deren Herstellung und deren Verwendung. The invention relates to a glazing arrangement with a light source and a light extraction means, a method for their production and their use.
Kraftfahrzeuge verfügen im Innenraum über eine Lichtverteilung, die je nach Bedarf für eine dezente oder auffallende Ausleuchtung des Innenraums sorgt. Die Beleuchtung sorgt nicht nur für Orientierung im Fahrzeug, sondern kreiert auch eine angenehme Atmosphäre für Insassen. Verbundscheiben als Verglasungen aus zwei oder mehreren gläsernen oder polymeren Scheiben werden in Fahrzeugen als Windschutzscheiben, Heckscheiben, Seitenscheiben und Dachscheiben eingesetzt. Bei beleuchtbaren oder beleuchteten Verglasungen wird unter Ausnutzung der Total reflexion Licht einer Lichtquelle in einen flächigen Lichtleiter in Form einer Scheibe der Verglasung eingekoppelt. Motor vehicles have a light distribution in the interior, which provides for a discreet or conspicuous illumination of the interior, depending on requirements. The lighting not only provides orientation in the vehicle, but also creates a pleasant atmosphere for the occupants. Composite panes as glazing made from two or more glass or polymer panes are used in vehicles as windshields, rear windows, side windows and roof windows. In the case of illuminable or illuminated glazing, light from a light source is coupled into a flat light guide in the form of a pane of the glazing using total reflection.
WO 2010/049638 A1 , WO 2013/053629 A1 , WO 2014060409 A1 oder WO 2015/095288 A2 offenbaren die Einkopplung von Licht über eine Seitenfläche in eine Glasscheibe. Wenn die Lichtquelle sehr nah an der Glaskante platziert wird, kann auf diese Weise sehr effizient und über die gesamte Breite des Lichtleiters Licht in den Lichtleiter eingekoppelt werden. Dadurch kann eine sehr homogene flächige Beleuchtung erreicht werden. Aus der WO2013/110885 A1 , WO2018178591 A1 oder 2019/105855 A1 ist bekannt die Lichtquelle in eine Ausnehmung anzuordnen und dadurch das Licht in die Scheibe einzukoppeln. WO 2010/049638 A1, WO 2013/053629 A1, WO 2014060409 A1 or WO 2015/095288 A2 disclose the coupling of light into a glass pane via a side surface. If the light source is placed very close to the edge of the glass, light can be coupled into the light guide very efficiently and over the entire width of the light guide. As a result, a very homogeneous, planar illumination can be achieved. It is known from WO2013/110885 A1, WO2018178591 A1 or 2019/105855 A1 to arrange the light source in a recess and thereby couple the light into the pane.
WO 2020/201973 A1 offenbart ein Verfahren zur Herstellung einer beleuchteten und gekrümmten Verbundscheibe für Kraftfahrzeuge mit einer lichtleitenden Glasschicht. WO 2020/201973 A1 discloses a method for producing an illuminated and curved composite pane for motor vehicles with a light-conducting glass layer.
Die Lichtreflektionen gelangen durch mehrfaches Reflektieren an den parallelen Oberflächen der Scheibe bis in den Randbereich der Scheibe, wo sie wieder aus der Scheibe austreten können. Dies erzeugt einen beleuchteten Randbereich. Dieser unerwünschte Lichteffekt im Randbereich der Scheibe ist durch einen Betrachter gut wahrnehmbar. The light reflections reach the edge area of the pane as a result of multiple reflections on the parallel surfaces of the pane, where they can emerge from the pane again. This creates a lighted edge area. This undesired light effect in the edge area of the pane can easily be perceived by an observer.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine verbesserte Verglasungsanordnung bereitzustellen, bei der in die Scheibe eingekoppeltes Licht nicht als Streulicht im Randbereich der Schiebe wahrgenommen werden kann. Diese Aufgabe wird gelöst durch eine Verglasungsanordnung gemäß Anspruch 1 . Bevorzugte Ausführungen gehen aus den Unteransprüchen hervor. The object of the present invention is to provide an improved glazing arrangement in which light coupled into the pane cannot be perceived as scattered light in the edge area of the sliding panel. This object is solved by a glazing arrangement according to claim 1 . Preferred embodiments emerge from the dependent claims.
Die erfindungsgemäße Verglasungsanordnung umfasst mindestens eine erste Scheibe, eine Lichtquelle zum Erzeugen von in die erste Scheibe einkoppelbarem Licht und ein Lichtauskopplungsmittel zum Auskoppeln von Licht aus der ersten Scheibe, wobei die erste Scheibe dazu vorgesehen ist, eingekoppeltes Licht zumindest teilweise weiterzuleiten. Die erste Scheibe weist mindestens eine erste Oberfläche (IV) und eine zweite Oberfläche (III) auf. Die Lichtauskopplungsmittel sind dazu vorgesehen, das Licht über eine der zwei Oberflächen (III, IV) auszukoppeln. Die erste Scheibe ist über eine Zwischenschicht mit einer zweiten Scheibe zu einer Verbundscheibe verbunden. The glazing arrangement according to the invention comprises at least a first pane, a light source for generating light that can be coupled into the first pane, and a light output coupling means for coupling light out of the first pane, the first pane being provided to at least partially forward coupled light. The first disc has at least a first surface (IV) and a second surface (III). The light outcoupling means are provided for outcoupling the light via one of the two surfaces (III, IV). The first pane is connected to a second pane via an intermediate layer to form a composite pane.
Die Verglasungsanordnung umfasst auch einen Randbereich, der sich von einer Scheibenkante der ersten Scheibe über mindestens 1 mm bis höchstens 500 mm auf einer der Oberflächen (III, IV) der ersten Scheibe erstreckt sowie ein Absorptionsmittel zur Absorption von in der ersten Scheibe eingekoppeltem Licht, das in dem Randbereich angeordnet ist. Das Absorptionsmittel ist als eine erste Abdeckschicht ausgebildet, die an der Zwischenschicht angeordnet ist. Weiterhin kann das Absorptionsmittel eine zweite Abdeckschicht, die an der ersten Oberfläche (IV) der ersten Scheibe angeordnet ist, umfassen. Da eine Lichtauskopplung an den Rändern der Verbundscheibe nicht gewünscht ist, weist der Randbereich der ersten Scheibe die Abdeckschichten auf, welche das Streulicht absorbieren. Dadurch wird mit geringem Aufwand das Streulicht im Randbereich der Verbundscheibe verhindert. Die erste Abdeckschicht und die zweite Abdeckschicht können sich von der Scheibenkante der ersten Scheibe über 1 mm bis 500 mm, bevorzugt 10 mm bis 150 mm, besonders bevorzugt 10 mm bis 15 mm erstrecken. The glazing arrangement also comprises an edge region, which extends from a pane edge of the first pane over at least 1 mm to at most 500 mm on one of the surfaces (III, IV) of the first pane, as well as an absorption means for absorbing light coupled into the first pane, which is arranged in the edge area. The absorbent is designed as a first covering layer which is arranged on the intermediate layer. Furthermore, the absorbent may comprise a second cover layer arranged on the first surface (IV) of the first pane. Since it is not desirable for light to be coupled out at the edges of the composite pane, the edge area of the first pane has the cover layers, which absorb the scattered light. This prevents the scattered light in the edge area of the laminated pane with little effort. The first covering layer and the second covering layer can extend from the pane edge of the first pane over 1 mm to 500 mm, preferably 10 mm to 150 mm, particularly preferably 10 mm to 15 mm.
Die zweite Abdeckschicht ist an der ersten Oberfläche (IV) der ersten Scheiben angeordnet. Dadurch wird das Streulicht im Randbereich an beiden Hauptoberflächen der Verbundscheibe absorbiert. Die zweite Scheibe weist eine dritte Abdeckschicht auf. Insbesondere können sich die erste Abdeckschicht, die zweite Abdeckschicht und die dritte Abdeckschicht zumindest teilweise in Durchsichtrichtung der Verbundscheibe überlappen. Somit wird das Streulicht im Randbereich zu den beiden Hauptseiten der Verbundscheibe besonders effektiv absorbiert. The second covering layer is arranged on the first surface (IV) of the first panes. As a result, the scattered light in the edge area is absorbed on both main surfaces of the laminated pane. The second pane has a third cover layer. In particular, the first covering layer, the second covering layer and the third covering layer can at least partially overlap in the viewing direction of the laminated pane. In this way, the scattered light in the edge area on the two main sides of the laminated pane is absorbed particularly effectively.
In einer Weiterbildung der Erfindung sind die erste Abdeckschicht, die zweite Abdeckschicht und/oder die dritte Abdeckschicht opak, insbesondere blickdicht. Die Abdeckschichten werden auch als Abdeckdruck oder Schwarzdruck bezeichnet. Der Abdeckdruck ist aus einer Druckfarbe ausgebildet. Die erste Abdeckschicht ist eine gedruckte opake Schicht. Die gedruckte opake Schicht kann eine lichtundurchlässige Schicht sein, welche mittels eines Druckverfahrens auf der Zwischenschicht aufgetragen ist. Die gedruckte opake Schicht ist insbesondere schwarz. In a development of the invention, the first covering layer, the second covering layer and/or the third covering layer are opaque, in particular opaque. The cover layers are also referred to as cover print or black print. The masking print is formed from one ink. The first cover layer is a printed opaque layer. The The printed opaque layer can be an opaque layer which is applied to the intermediate layer by means of a printing process. In particular, the printed opaque layer is black.
Die zweite Abdeckschicht und/oder die dritte Abdeckschicht können aus einer opaken Emaille ausgebildet sein, bevorzugt aufgebracht als Siebdruck oder als Digitaldruck. Die Emaille kann Glasfritten und/oder mineralische Fritten und optional mindestens ein Pigment enthalten, bevorzugt Glasfritten und/oder mineralische Fritten auf Basis von Oxiden ausgewählt aus Bor, Wismut, Zink, Silizium, Aluminium und Natrium. Das Pigment sorgt für die Opazität der Abdeckschicht. Das Pigment kann ein Schwarzpigment, beispielsweise Pigmenttruß (Carbon Black), Anilinschwarz, Beinschwarz, Eisenoxidschwarz, Spinellschwarz und/oder Graphit aufweisen. Alternativ können die erste, zweite und/oder dritte Abdeckschicht als ein insbesondere schwarzes Klebeband oder ein Grundschicht, sogenannter Primer, ausgebildet sein. Der Primer kann eine Sol-Gel-Schicht aus Siliziumoxid in Mischung mit anderen anorganischen Oxiden umfassen. The second cover layer and/or the third cover layer can be formed from an opaque enamel, preferably applied as a screen print or as a digital print. The enamel can contain glass frits and/or mineral frits and optionally at least one pigment, preferably glass frits and/or mineral frits based on oxides selected from boron, bismuth, zinc, silicon, aluminum and sodium. The pigment provides the opacity of the cover layer. The pigment can include a black pigment, for example carbon black, aniline black, bone black, iron oxide black, spinel black and/or graphite. Alternatively, the first, second and/or third cover layer can be formed as an in particular black adhesive tape or a base layer, a so-called primer. The primer may comprise a sol-gel layer of silicon oxide mixed with other inorganic oxides.
Die erste Abdeckschicht, die zweite Abdeckschicht und die dritte Abdeckschicht können vollflächig und/oder rahmenartig ausgebildet sein. The first covering layer, the second covering layer and the third covering layer can be designed over the whole area and/or in the manner of a frame.
In einer weiteren Ausführungsform umfasst die Verbundscheibe eine umlaufende Scheibenkante, wobei das Absorptionsmittel zumindest abschnittsweise entlang der umlaufenden Scheibenkante angeordnet ist oder das Absorptionsmittel sich umlaufend entlang der gesamten umlaufenden Scheibenkante erstreckt. Die Verbundscheibe weist einen Durchsichtbereich auf, in dem die Verbundscheibe keine Abdeckschicht aufweist. Der Durchsichtbereich der Verbundscheibe macht mindestens 30%, bevorzugt 50% der Fläche der Verbundscheibe aus. Ist die Verbundscheibe als eine Dachscheibe oder Windschutzscheibe ausgebildet, kann der Durchsichtbereich mindestens 70% oder mindestens 80 % der Fläche der Verbundscheibe ausmachen. In a further embodiment, the laminated pane comprises a peripheral pane edge, the absorbent being arranged at least in sections along the peripheral pane edge or the absorbent extending peripherally along the entire peripheral pane edge. The laminated pane has a see-through area in which the laminated pane has no cover layer. The see-through area of the laminated pane makes up at least 30%, preferably 50%, of the area of the laminated pane. If the composite pane is designed as a roof pane or windshield, the see-through area can make up at least 70% or at least 80% of the area of the composite pane.
Weiterhin kann die Lichtquelle eine oder mehrere Leuchtdioden (LED, LED-Modul, LED- Leuchte) umfassen. Diese Art von Lichtquellen ist besonders hell und effektiv. Die erste Scheibe weist mindestens eine Aussparung zur Aufnahme der Lichtquelle auf. Dadurch kann eine Verringerung des in die Umgebung außerhalb der Verbundscheibe gestreuten Lichtes und eine verbesserte Lichteinkopplung in die erste Scheibe erzielt werden. Alternativ kann die Lichtquelle außerhalb der Verbundscheibe an einer Seitenfläche oder der ersten Oberflächen (IV) der ersten Scheibe angeordnet sein, sodass die Einkopplung von Licht über eine äußere Seitenfläche oder der ersten Oberfläche (IV) in die erste Scheibe stattfindet. Furthermore, the light source can include one or more light-emitting diodes (LED, LED module, LED lamp). This type of light source is particularly bright and effective. The first pane has at least one recess for receiving the light source. As a result, a reduction in the light scattered into the environment outside of the laminated pane and improved coupling of light into the first pane can be achieved. Alternatively, the light source can be outside of the laminated pane on a side surface or on the first surfaces (IV) of the first pane, so that light is coupled into the first pane via an outer side surface or the first surface (IV).
Die erste Scheibe und die zweite Scheibe enthalten bevorzugt Glas, besonders bevorzugt Floatglas aus klarem Glas, ganz besonders bevorzugt Diamantglas. Alternativ können die Scheiben auch Flachglas wie Kalk-Natron-Glas, Borosilikatglas oder Quarzglas, oder klare Kunststoffe, starre klare Kunststoffe, insbesondere Polyethylen, Polypropylen, Polycarbonat, Polymethylmethacrylat, Polystyrol, Polyamid, Polyester, Polyvinylchlorid und/oder Gemische davon, enthalten. Die erste Scheibe und/oder zweite Scheibe sind bevorzugt transparent, insbesondere für die Verwendung der Scheiben als Dachscheibe, Windschutzscheibe oder Rückscheibe eines Fahrzeugs oder anderen Verwendungen, bei denen eine hohe Lichttransmission erwünscht ist. Insbesondere besteht zumindest die erste Scheibe und bevorzugt auch die zweite Scheibe aus Klarglas. The first pane and the second pane preferably contain glass, particularly preferably float glass made from clear glass, very particularly preferably diamond glass. Alternatively, the panes can also contain flat glass such as soda-lime glass, borosilicate glass or quartz glass, or clear plastics, rigid clear plastics, in particular polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polyamide, polyester, polyvinyl chloride and/or mixtures thereof. The first pane and/or second pane are preferably transparent, in particular for use of the panes as roof panes, windshields or rear panes of a vehicle or other uses where high light transmission is desired. In particular, at least the first pane and preferably also the second pane are made of clear glass.
Eine Beschichtung, insbesondere eine Scheibe oder ein Gegenstand wird als transparent verstanden, wenn die Beschichtung, die Scheibe oder der Gegenstand eine Transmission im sichtbaren Spektralbereich von größer 20%, bevorzugt 50%, besonders bevorzugt von größer 70 %, insbesondere von größer 85% aufweist. A coating, in particular a pane or an object, is understood to be transparent if the coating, pane or object has a transmission in the visible spectral range of greater than 20%, preferably 50%, particularly preferably greater than 70%, in particular greater than 85% .
Für Scheiben, die nicht im verkehrsrelevanten Sichtfeld des Fahrers liegen, beispielsweise für Dachscheiben, kann die Transmission aber auch viel geringer sein, beispielsweise größer als 5 %. Dazu kann beispielsweise die zweite Scheibe und/oder die Zwischenschicht getönt oder gefärbt sein. However, for panes that are not in the driver's field of vision relevant to traffic, for example for roof panes, the transmission can also be much lower, for example greater than 5%. For this purpose, for example, the second pane and/or the intermediate layer can be tinted or colored.
Die Dicke der ersten Scheibe und/oder zweiten Scheibe kann breit variieren und so hervorragend den Erfordernissen des Einzelfalls angepasst werden. Vorzugsweise werden Standardstärken von 1 ,0 mm bis 25 mm, bevorzugt von 1 ,4 mm bis 2,5 mm für Fahrzeugglas und bevorzugt von 4 mm bis 25 mm für Möbel, Geräte und Gebäude, verwendet. Die Größe der Scheiben kann breit variieren und richtet sich nach der Größe der erfindungsgemäßen Verwendung. Die erste Scheibe und zweite Scheibe weisen beispielsweise im Fahrzeugbau und Architekturbereich übliche Flächen von 200 cm2 bis zu 20 m2 auf. The thickness of the first pane and/or second pane can vary widely and can thus be perfectly adapted to the requirements of the individual case. Standard thicknesses of 1.0 mm to 25 mm, preferably 1.4 mm to 2.5 mm for vehicle glass and preferably 4 mm to 25 mm for furniture, appliances and buildings are preferably used. The size of the discs can vary widely and depends on the size of the use according to the invention. The first pane and second pane have areas of 200 cm 2 up to 20 m 2 , which are common in vehicle construction and architecture, for example.
Die Verbundscheibe kann eine beliebige dreidimensionale Form aufweisen. Vorzugsweise hat die dreidimensionale Form keine Schattenzonen, so dass sie beispielsweise durch Kathodenzerstäubung mit weiteren Beschichtungen beschichtet werden kann. Bevorzugt sind die Scheiben planar oder leicht oder stark in einer Richtung oder in mehreren Richtungen des Raumes gebogen. Insbesondere werden planare Substrate verwendet. Die Scheiben können farblos oder gefärbt sein. The composite pane can have any three-dimensional shape. The three-dimensional shape preferably has no shadow zones, so that it can be coated with further coatings, for example by sputtering. Preferably, the discs are planar or light or strong in one or more directions of the space curved. In particular, planar substrates are used. The discs can be colorless or colored.
Die erste Scheibe und die zweite Scheibe werden durch mindestens die Zwischenschicht miteinander verbunden. Die Zwischenschicht ist bevorzugt transparent oder getönt oder gefärbt. Die Zwischenschicht enthält vorzugsweise mindestens einen Kunststoff, bevorzugt Polyvinylbutyral (PVB), Ethylenvinylacetat (EVA) und / oder Polyethylenterephthalat (PET) oder besteht daraus. Die Zwischenschicht kann aber auch beispielsweise Polyurethan (PU), Polypropylen (PP), Polyacrylat, Polyethylen (PE), Polycarbonat (PC), Polymethylmetacrylat, Polyvinylchlorid, Polyacetatharz, Gießharze, Acrylate, fluorinierte Ethylen-Propylene, Polyvinylfluorid und/oder Ethylen-Tetrafluorethylen, oder Copolymere oder Gemische davon enthalten. Die Zwischenschicht kann durch eine oder auch durch mehrere übereinander angeordnete Folien ausgebildet werden, wobei die Dicke einer Folie bevorzugt von 0,025 mm bis 1 mm beträgt, typischerweise 0,38 mm oder 0,76 mm. Die Zwischenschichten können bevorzugt thermoplastisch sein und nach der Lamination die erste Scheibe, die zweite Scheibe und eventuelle weitere Zwischenschichten miteinander verkleben. Besonders vorteilhaft sind sogenannte akustik-dämpfende Zwischenschichten, die bevorzugt aus drei Lagen PVB bestehen, wobei die mittlere Lage weicher ausgebildet ist als die zwei äußeren Lagen. The first pane and the second pane are connected to one another by at least the intermediate layer. The intermediate layer is preferably transparent or tinted or colored. The intermediate layer preferably contains or consists of at least one plastic, preferably polyvinyl butyral (PVB), ethylene vinyl acetate (EVA) and/or polyethylene terephthalate (PET). However, the intermediate layer can also be, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetate resin, casting resins, acrylates, fluorinated ethylene-propylene, polyvinyl fluoride and/or ethylene-tetrafluoroethylene , or contain copolymers or mixtures thereof. The intermediate layer can be formed by one film or by a plurality of films arranged one on top of the other, the thickness of a film preferably being from 0.025 mm to 1 mm, typically 0.38 mm or 0.76 mm. The intermediate layers can preferably be thermoplastic and, after lamination, can bond the first pane, the second pane and any further intermediate layers to one another. So-called acoustic-damping intermediate layers, which preferably consist of three layers of PVB, are particularly advantageous, with the middle layer being softer than the two outer layers.
Die Zwischenschicht kann auch eine funktionale Schicht aufweisen, insbesondere eine Infrarotstrahlung reflektierende Schicht, eine Infrarotstrahlung absorbierende Schicht, eine UV-Strahlung absorbierende Schicht, eine zumindest abschnittsweise gefärbte Schicht und/oder eine zumindest abschnittsweise getönte Schicht. So kann die thermoplastische Zwischenschicht beispielsweise auch ein Bandfilter sein. The intermediate layer can also have a functional layer, in particular a layer that reflects infrared radiation, a layer that absorbs infrared radiation, a layer that absorbs UV radiation, a layer that is colored at least in sections and/or a layer that is tinted at least in sections. For example, the thermoplastic intermediate layer can also be a belt filter.
Die Begriffe „erste Scheibe“ und „zweite Scheibe“ sind zur Unterscheidung der beiden Scheiben bei einer erfindungsgemäßen Verbundscheibe gewählt. Mit den Begriffen ist keine Aussage über die geometrische Anordnung verbunden. Ist die erfindungsgemäße Verbundscheibe beispielsweise dafür vorgesehen, in einer Öffnung, beispielsweise eines Fahrzeugs oder eines Gebäudes, den Innenraum gegenüber der äußeren Umgebung abzutrennen, so kann die erste Scheibe dem Innenraum oder der äußeren Umgebung zugewandt sein. The terms “first pane” and “second pane” are chosen to distinguish between the two panes in a composite pane according to the invention. No statement about the geometric arrangement is connected with the terms. If the composite pane according to the invention is intended, for example, to separate the interior from the external environment in an opening, for example in a vehicle or a building, the first pane can face the interior or the external environment.
In einer vorteilhaften Ausgestaltung ist die Verbundscheibe eine Dachscheibe eines Kraftfahrzeugs ist, wobei die ersten Scheibe die Innenscheibe ist und die zweite Scheibe die Außenscheibe ist. Ferner kann die erste Scheibe und/oder die zweite Scheibe weitere geeignete Beschichtungen aufweisen, beispielsweise eine Antireflexionsbeschichtung, eine Antihaftbeschichtung, eine Antikratzbeschichtung, eine photokatalytische Beschichtung, eine Sonnenschutzbeschichtung und/oder Low-E-Beschichtung. In an advantageous embodiment, the composite pane is a roof pane of a motor vehicle, the first pane being the inner pane and the second pane being the outer pane. Furthermore, the first pane and/or the second pane can have other suitable coatings, for example an anti-reflection coating, an anti-stick coating, an anti-scratch coating, a photocatalytic coating, a sun protection coating and/or low-E coating.
Weiterhin kann die Verglasungsanordnung optional weitere funktionelle Elemente, insbesondere elektronisch steuerbare optische Elemente umfassen, beispielsweise PDLC- Elemente, elektrochrome Elemente oder ähnliches, die typischerweise zwischen der ersten Scheibe und der zweiten Scheibe angeordnet sind. Furthermore, the glazing arrangement can optionally include further functional elements, in particular electronically controllable optical elements, for example PDLC elements, electrochromic elements or the like, which are typically arranged between the first pane and the second pane.
Die erste Scheibe und die zweite Scheibe werden über die Zwischenschicht miteinander laminiert, beispielsweise durch Autoklavverfahren, Vakuumsackverfahren, Vakuumringverfahren, Kalanderverfahren, Vakuumlaminatoren oder Kombinationen davon. Die Verbindung der Scheibe erfolgt dabei üblicherweise unter Einwirkung von Hitze, Vakuum und/oder Druck. The first pane and the second pane are laminated together via the intermediate layer, for example by autoclave processes, vacuum bag processes, vacuum ring processes, calendering processes, vacuum laminators, or combinations thereof. The pane is usually connected under the action of heat, vacuum and/or pressure.
In einem weiteren Aspekt umfasst die vorliegende Erfindung ein Fahrzeug, insbesondere Personenkraftwagen, mit einer erfindungsgemäßen Verglasungsanordnung. In a further aspect, the present invention includes a vehicle, in particular a passenger car, with a glazing arrangement according to the invention.

Figur 1 zeigt eine Draufsicht auf eine Ausgestaltung einer erfindungsgemäßen Verglasungsanordnung 10 mit einer Verbundscheibe 101 am Beispiel einer Dachscheibe für ein Fahrzeug. Alternativ kann die Verbundscheibe 101 eine Bauverglasung oder Bauteile eines Möbels oder elektrischen Geräts sein. Die Verglasungsanordnung 10 kann auch Teil einer Isolierverglasung sein und beispielsweise als Außen- oder Innenscheibe in einem Fenster eines Gebäudes dienen. Ferner ist die Verglasungsanordnung 10 in einem Innenraum einbaubar und kann beispielsweise als Verglasung eines Konferenzraums dienen. FIG. 1 shows a plan view of an embodiment of a glazing arrangement 10 according to the invention with a laminated pane 101 using the example of a roof pane for a vehicle. Alternatively, the laminated pane 101 can be building glazing or components of a piece of furniture or an electrical device. The glazing arrangement 10 can also be part of insulating glazing and serve, for example, as an outer or inner pane in a window of a building. Furthermore, the glazing arrangement 10 can be installed in an interior space and can be used, for example, as glazing for a conference room.
Die Verglasungsanordnung 10 umfasst die Verbundscheibe 101 und zwei Lichtquellen 2. Die Lichtquellen 2 sind dazu vorgesehen, Licht im sichtbaren Bereich zu emittieren. Alternativ können sie infrarotes oder ultraviolettes Licht aussenden. Jede Lichtquelle 2 der Verglasungsanordnung 10 kann eine oder mehrere Leuchtdioden (LED, LED-Modul, LED- Leuchte) sein. Eine Lichtquelle 2 kann auch eine organische Leuchtdiode (OLED) umfassen. The glazing arrangement 10 comprises the laminated pane 101 and two light sources 2. The light sources 2 are intended to emit light in the visible range. Alternatively, they can emit infrared or ultraviolet light. Each light source 2 of Glazing assembly 10 may be one or more light emitting diodes (LED, LED module, LED light). A light source 2 can also include an organic light-emitting diode (OLED).
Die Verbundscheibe 101 weist weiterhin vier Lichtauskopplungsmittel 4 auf. Ein Lichtauskopplungsmittel 4 koppelt Licht aus der Verbundscheibe 101 aus. Die Lichtauskopplungsmittel 4 sind an der ersten Oberfläche IV (Hauptoberfläche der Verbundscheibe 101) angeordnet. An der Stelle, an der ein Lichtauskopplungsmittels 4 angeordnet ist, wird kann das Licht über die Oberfläche IV aus der Verbundscheibe 101 austreten. The laminated pane 101 also has four light decoupling means 4 . A light decoupling means 4 decouples light from the laminated pane 101 . The light extraction means 4 are arranged on the first surface IV (main surface of the laminated pane 101). At the point at which a light extraction means 4 is arranged, the light can emerge from the laminated pane 101 via the surface IV.
Das Lichtauskopplungsmittel 4 kann an jeder beliebigen Stelle der Oberfläche IV angeordnet sein. In Figur 1 umfasst das Lichtauskopplungsmittel 4 Strukturierungen der Oberfläche IV, an der die Totalreflexion innerhalb der Verbundscheibe 101 verhindert wird und Licht über die Oberfläche IV aus der Verbundscheibe 101 austreten kann. Alternativ kann das Lichtauskopplungsmittel 4 einen Aufdruck auf der Oberfläche IV oder in die Verbundscheibe 101 eingebrachte lichtstreuende, lichtbrechende, lichtbeugende oder lichtreflektierende Partikel oder Kavitäten umfassen. The light coupling-out means 4 can be arranged at any point on the surface IV. In FIG. 1, the light coupling-out means 4 comprises structuring of the surface IV, at which the total reflection within the composite pane 101 is prevented and light can emerge from the composite pane 101 via the surface IV. Alternatively, the light extraction means 4 can comprise an imprint on the surface IV or light-scattering, light-refracting, light-diffracting or light-reflecting particles or cavities introduced into the laminated pane 101 .
Im vorliegenden Ausführungsbeispiel hier ist das Lichtauskopplungsmittel 4 auch als ein Aufdruck aus feinen lichtstreuenden Partikeln auf die Oberfläche IV ausgebildet. Durch diese wird die Totalreflexion eines Lichtstrahls an der Grenzfläche zwischen Verbundscheibe 101 und umgebender Luft unterbrochen und Licht durch Streuung aus der Verbundscheibe 101 ausgekoppelt. In the present exemplary embodiment, the light decoupling means 4 is also designed as an imprint of fine, light-scattering particles on the surface IV. This interrupts the total reflection of a light beam at the interface between composite pane 101 and the surrounding air and light is coupled out of composite pane 101 by scattering.
Die Verbundscheibe 101 weist im Randbereich 7 ein Absorptionsmittel 8 zur Absorption von in der Verbundscheibe 101 eingekoppeltem Licht 3. Das Absorptionsmittel 8 ist als eine erste an einer Zwischenschicht 5 der Verbundscheibe 101 angeordnete Abdeckschicht 9 ausgebildet. Weiterhin umfasst das Absorptionsmittel 8 eine an der ersten Oberfläche IV angeordnete zweite Abdeckschicht 11 . The laminated pane 101 has an absorbent 8 in the edge region 7 for absorbing light 3 coupled into the laminated pane 101 . Furthermore, the absorbent 8 comprises a second cover layer 11 arranged on the first surface IV.
Die Verbundscheibe 101 umfasst eine umlaufende Scheibenkante 12, wobei sich das zweite Abdeckschicht 11 umlaufend entlang der gesamten umlaufenden Scheibenkante 12 erstreckt. Alternativ kann das Absorptionsmittel 8 zumindest abschnittsweise entlang der umlaufenden Scheibenkante 12 angeordnet sein. Die Breite des Randbereichs 7 wird von der Scheibenkante 12 gemessen und beträgt beispielsweise 10 mm. Überraschend hat sich gezeigt, dass eine Anordnung von Absorptionsmittel 8 im Randbereich 7 der Verbundscheibe 101 besonders effektiv das Streulicht an der Scheibenkante 12 verhindert. Dies ist besonders vorteilhaft bei Scheiben, deren Kantenbereich im Einbauzustand nicht verdeckt sind. Dank des Absorptionsmittels 8 sind die freistehenden Kanten verdunkelt und somit die durch die Lichtauskopplungsmitte 4 ausgebildeten leuchtenden Muster (beispielsweise Sterne) gut erkennbar. The laminated pane 101 comprises a peripheral pane edge 12 , with the second covering layer 11 extending circumferentially along the entire peripheral pane edge 12 . Alternatively, the absorbent 8 can be arranged at least in sections along the peripheral edge 12 of the pane. The width of the edge area 7 is measured from the pane edge 12 and is 10 mm, for example. Surprisingly, it has been shown that an arrangement of absorption means 8 in the edge region 7 of the laminated pane 101 prevents the scattered light at the pane edge 12 in a particularly effective manner. This is particularly advantageous for panes whose edges are not covered when installed. Thanks to the absorption means 8, the free-standing edges are darkened and the luminous patterns (e.g. stars) formed by the light outcoupling center 4 can thus be easily recognized.
Die Verbundscheibe 101 weist einen Durchsichtbereich 15 auf, in dem die Verbundscheibe keine Abdeckschicht aufweist. Der Durchsichtbereich 15 macht mindestens 70% der Oberfläche der Verbundscheibe 101 aus. The laminated pane 101 has a see-through area 15 in which the laminated pane has no cover layer. The see-through area 15 makes up at least 70% of the surface of the laminated pane 101 .
Figur 2 zeigt eine Querschnittsdarstellung der erfindungsgemäßen Verglasungsanordnung 10 aus Figur 1. Die Verbundscheibe 101 umfasst eine erste Scheibe 1 , die über eine Zwischenschicht 5 mit einer zweiten Scheibe 6 verbunden ist. Die erste Scheibe 1 , die Zwischenschicht 5 und die zweite Scheibe 6 wurden durch Lamination, insbesondere Autoklaven, miteinander verbunden. Die zweite Scheibe 6 weist eine erste Oberfläche I auf und eine weitere der ersten Oberfläche I gegenüberliegenden zweite Oberfläche II. FIG. 2 shows a cross-sectional representation of the glazing arrangement 10 according to the invention from FIG. The first pane 1, the intermediate layer 5 and the second pane 6 were connected to one another by lamination, in particular in an autoclave. The second pane 6 has a first surface I and another second surface II opposite the first surface I.
Die erste Scheibe 1 weist die erste Oberfläche IV auf und eine weitere der ersten Oberfläche IV gegenüberliegenden zweite Oberfläche III. Die Stirnflächen der Verbundscheibe 101 sind orthogonal zu den Oberflächen III, IV angeordnet. Die erste Scheibe 1 und die zweite Scheibe 6 bestehen beispielsweise aus Kalk-Natronglas. Die thermoplastische Zwischenschicht 3 ist beispielsweise aus einer 0,76 mm dicken PVB-Folie gebildet sowie mehreren Lagen eines thermoplastischen Materials enthalten. Die Dicke der ersten Scheibe 1 beträgt beispielsweise 1 ,6 mm und die Dicke der zweiten Scheibe 6 kann 2,1 mm betragen. Die erste Scheibe 1 und die zweite Scheibe 6 können beliebige Dicken aufweisen, beispielsweise gleich dick sein. Die Verbundscheibe 101 wird durch vier umlaufende Seitenflächen begrenzt. The first pane 1 has the first surface IV and a second surface III opposite the first surface IV. The end faces of the laminated pane 101 are arranged orthogonally to the surfaces III, IV. The first pane 1 and the second pane 6 consist, for example, of soda-lime glass. The thermoplastic intermediate layer 3 is formed, for example, from a 0.76 mm thick PVB film and contains several layers of a thermoplastic material. The thickness of the first pane 1 is 1.6 mm, for example, and the thickness of the second pane 6 can be 2.1 mm. The first pane 1 and the second pane 6 can have any thickness, for example the same thickness. The compound pane 101 is delimited by four circumferential side surfaces.
Die erste Scheibe 1 kann vorgespanntes, teilvorgespanntes oder nicht-vorgespanntes Glas aufweisen. Alternativ kann die erste Scheibe 1 aus einem Kunststoff, beispielsweise aus Polycarbonat bestehen. Die erste Scheibe 1 , die zweite Scheibe 6 und die Zwischenschicht 5 sind beispielsweise klar (weder getönt noch gefärbt). Alternativ kann die Zwischenschicht 5 eine getönte oder gefärbte PVB-Folie aufweisen. Alternativ oder zusätzlich kann die zweite Scheibe 6 dunkel getönt sein. The first pane 1 can comprise toughened, partially toughened or non-toughened glass. Alternatively, the first pane 1 can be made of a plastic, for example made of polycarbonate. For example, the first pane 1, the second pane 6 and the intermediate layer 5 are clear (neither tinted nor colored). Alternatively, the intermediate layer 5 can have a tinted or colored PVB film. Alternatively or additionally, the second pane 6 can be tinted dark.
Die erste Scheibe 1 weist eine Aussparungen 14 auf, in welche eine der zwei Lichtquellen 2 eingesetzt ist. Die Aussparung 14 erstreckt sich durchgehend von der ersten Oberfläche IV der ersten Scheibe 1 bis zur zweiten Oberfläche III der ersten Scheibe 1. Die ZwischenschichtThe first pane 1 has a recess 14 into which one of the two light sources 2 is inserted. The recess 14 extends continuously from the first surface IV of the first pane 1 to the second surface III of the first pane 1. The intermediate layer
5 wurde im Bereich der Aussparung 14 nicht entfernt. Die Lichtquelle 2 befindet sich vollständig innerhalb der Verbundscheibe 101 . Das von der Lichtquelle 2 emittierte Licht 3 ist in Richtung der Scheibe 1 gerichtet. Die Scheibe 1 ist dazu vorgesehen das eingekoppelte Licht 3 in Längsrichtung durch die Scheibe 1 weiterzuleiten. Die erste Scheibe 1 stellt bevorzugt die Innenscheibe und die zweite Scheibe 6 die Außenscheibe der Verbundscheibe 101 dar. Diese Anordnung ist aufgrund der Position der Lichtquellen 2 in ersten Scheibe 1 besonders vorteilhaft, da sich die Lichtauskopplung in Richtung eines (Fahrzeugs-)lnnenraum stattfindet, was zu einer angenehmen Atmosphäre im Innenraum führt. Alternativ kann die zweite Scheibe5 was not removed in the area of recess 14. The light source 2 is located entirely within the laminated pane 101 . The light 3 emitted by the light source 2 is directed in the direction of the pane 1 . The pane 1 is intended to forward the coupled-in light 3 through the pane 1 in the longitudinal direction. The first pane 1 is preferably the inner pane and the second pane 6 is the outer pane of the composite pane 101. This arrangement is particularly advantageous due to the position of the light sources 2 in the first pane 1, since the light is coupled out in the direction of a (vehicle) interior, which leads to a pleasant atmosphere in the interior. Alternatively, the second disc
6 auch die Innenscheibe und die erste Scheibe 1 die Außenscheibe darstellen. 6 also represent the inner pane and the first pane 1 represents the outer pane.
Das Absorptionsmittel 8 umfasst die erste Abdeckschicht 9, die zweite Abdeckschicht 11 und eine dritte Abdeckschicht 13. Die erste Abdeckschicht 9 ist im Randbereich der Zwischenschicht 5 aufgebracht. Die erste Abdeckschicht 9 ist eine gedruckte opake Schicht. Die gedruckte opake Schicht kann eine lichtundurchlässige Schicht sein, welche mittels eines Druckverfahrens auf der Zwischenschicht 5 aufgebracht wurde. Die gedruckte opake Schicht ist schwarz. Alternativ kann die Schicht grau und dunkel sein. The absorbent 8 comprises the first covering layer 9, the second covering layer 11 and a third covering layer 13. The first covering layer 9 is applied in the edge region of the intermediate layer 5. FIG. The first cover layer 9 is a printed opaque layer. The printed opaque layer can be an opaque layer which has been applied to the intermediate layer 5 by means of a printing process. The printed opaque layer is black. Alternatively, the layer can be gray and dark.
Bei der Abdeckschichten 11 und 13 handelt es sich um einen peripheren, d.h. rahmenartigen Abdeckdruck. Die Abdeckschichten 9, 11 und 13 sind opak und vollflächig ausgebildet. Cover layers 11 and 13 are peripheral, i.e. frame-like, cover prints. The cover layers 9, 11 and 13 are opaque and formed over the entire surface.
Zusätzlich ist die zweite Abdeckschicht 11 an der ersten Oberfläche IV der ersten Scheibe 1 angeordnet. Die dritte Abdeckschicht 13 befindet sich an der zweiten Oberfläche II der zweiten Scheibe 6. Die Lichtquelle 2 wird in Durchsichtrichtung von der dritten Abdeckschicht 13 überdeckt. Die ersten Abdeckschicht 9 und die dritte Abdeckschicht 13 überlappen sich in Durchsichtrichtung der Verbundscheibe 101. Da eine Lichtauskopplung an den Rändern der Verbundscheibe 101 nicht gewünscht ist, weist der Randbereich 7 der ersten Scheibe 1 zumindest teilweise die erste Abdeckschicht 9, die zweite Abdeckschicht 11 und die dritte Abdeckschicht 13 auf, die das Streulicht absorbieren. Dadurch wird mit geringem Aufwand das Streulicht im Randbereich 7 der Verbundscheibe 101 stark reduziert. In addition, the second covering layer 11 is arranged on the first surface IV of the first pane 1 . The third cover layer 13 is located on the second surface II of the second pane 6. The light source 2 is covered by the third cover layer 13 in the viewing direction. The first covering layer 9 and the third covering layer 13 overlap in the viewing direction of the laminated pane 101. Since light is not desired to be coupled out at the edges of the laminated pane 101, the edge region 7 of the first pane 1 has at least partially the first covering layer 9, the second covering layer 11 and the third cover layer 13, which absorb the scattered light. As a result, the scattered light in the edge region 7 of the laminated pane 101 is greatly reduced with little effort.
Die zweite Abdeckschicht 11 und die dritte Abdeckschicht 13 enthalten Pigmente und Glasfritten. Sie kann weitere chemische Verbindungen enthalten. Die Glasfritten können an- oder aufgeschmolzen und der Abdeckschicht 11 und 13 dadurch dauerhaft mit der Glasoberfläche verbunden (verschmolzen oder gesintert) werden. Das Pigment sorgt für die Opazität der ersten und zweiten Abdeckschicht 11 , 13. Solche Abdeckschichten werden als Emaille aufgebracht. Figur 3 zeigt eine schematische Querschnittdarstellung einer zweiten Ausgestaltung der erfindungsgemäßen Verglasungsanordnung 10. Die in Figur 3 dargestellte Verglasungsanordnung 10 eignet sich besonders gut als Dachscheibe eines Kraftfahrzeugs. Die Verglasungsanordnung 10 aus Figur 3 hat einen ähnlichen Aufbau wie die Verglasungsanordnung 10 aus Figur 2. Die zweite Scheibe 6 (Außenscheibe) gleicht derThe second covering layer 11 and the third covering layer 13 contain pigments and glass frits. It may contain other chemical compounds. The glass frits can be melted on or on and the cover layer 11 and 13 can thereby be permanently connected (fused or sintered) to the glass surface. The pigment provides the opacity of the first and second cover layers 11, 13. Such cover layers are applied as an enamel. FIG. 3 shows a schematic cross-sectional illustration of a second embodiment of the glazing arrangement 10 according to the invention. The glazing arrangement 10 shown in FIG. 3 is particularly suitable as a roof pane of a motor vehicle. The glazing arrangement 10 from FIG. 3 has a similar structure to the glazing arrangement 10 from FIG
Scheibe 6 aus Figur 2. Im Unterschied zur Figur 2 ist jedoch die zweite Abdeckschicht 11 auf der ersten Oberfläche IV der ersten Scheibe 1 rahmenförmig um den Durchsichtbereich 15 aufgebracht. Die erste Scheibe 1 ist beispielsweise dafür vorgesehen, in Einbaulage einem Innenraum eines Fahrzeugs zugewandt zu sein. Die erste Oberfläche IV der ersten Scheibe 1 ist vom Innenraum aus zugänglich, wogegen die erste Oberfläche I der zweiten Scheibe 6 bezüglich des Fahrzeuginnenraums nach außen weist. Pane 6 from FIG. 2. In contrast to FIG. 2, however, the second cover layer 11 is applied to the first surface IV of the first pane 1 in the shape of a frame around the viewing area 15 . The first pane 1 is provided, for example, to face an interior of a vehicle in the installed position. The first surface IV of the first pane 1 is accessible from the interior, whereas the first surface I of the second pane 6 faces outwards with respect to the vehicle interior.
