Description

[0001] This invention relates to an assembly glass device having a light source and an optical coupling output unit.

[0002] Motor vehicles have light distribution within their interior spaces, providing soft or bright illumination as needed. Illumination not only provides positioning within the vehicle but also creates a comfortable atmosphere for occupants. Composite glass panels, made of two or more glass or polymer glass sheets, are used in vehicles as windshields, rear windows, side windows, and roof windows. In the case of illuminated or illuminated composite glass, light from a light source is coupled into a flat light conductor in the form of the glass sheet by utilizing total internal reflection.

[0003] WO 2010 / 049638 A1, WO 2013 / 053629 A1, WO 2014060409 A1, or WO 2015 / 095288A2 disclose the input of light into a glass plate via a side surface coupling. If the light source is placed very close to the edge of the glass, light can be coupled into the light conductor very efficiently and over the entire width of the light conductor. This allows for very uniform planar illumination. WO2013 / 110885A1, WO2018178591 A1, or WO2019 / 105855A1 disclose the arrangement of a light source within a notch, thereby coupling light into the glass plate.

[0004] Due to multiple reflections on the parallel surface of the glass plate, the light is reflected to the edge region of the glass plate, where it can leave the glass plate again. This produces an illuminated edge region. This undesirable light effect in the edge region of the glass plate is easily perceived by the observer.

[0005] The object of the present invention is to provide an improved glass assembly apparatus in which light coupled into a glass plate is not perceived as scattered light in the edge regions of the glass plate.

[0006] This objective is achieved by the glass assembly apparatus according to the invention. Preferred embodiments will be derived from further description.

[0007] The glass assembly device according to the invention includes a first glass plate having a first surface (IV) and a second surface (III). The first glass plate is configured to further conduct at least partially the coupled-input light. Furthermore, the glass assembly device includes a light source for generating light that can be coupled into the first glass plate, and a light coupling output unit for coupling light out of the first glass plate via one of the two surfaces (III, IV). Additionally, the first glass plate is bonded to a second glass plate via an interlayer to form a composite glass plate. The glass assembly device also includes an edge region extending at least 1 mm to 500 mm from the edge of the first glass plate on one of the surfaces (III, IV), and an absorption unit for absorbing the light coupled into the first glass plate, disposed in the edge region, wherein the absorption unit includes an opaque, particularly non-transparent, thermoplastic interlayer.

[0008] Since it is undesirable for light to couple out at the edges of the composite glass plate, the edge region of the first glass plate has an opaque thermoplastic interlayer that absorbs scattered light. This significantly reduces scattered light in the edge region of the composite glass plate with minimal complexity. Preferably, the opaque thermoplastic interlayer is dyed a dark color, such as black or gray. Dyeing it black is particularly effective in preventing scattered light from escaping from the composite glass plate in the edge region. However, the opaque thermoplastic interlayer can also be various other colors.

[0009] In a particularly preferred embodiment, the intermediate layer comprises a transparent thermoplastic intermediate layer and an opaque thermoplastic intermediate layer. In the context of this invention, "opaque" is understood to mean an object, particularly a glass plate, layer, or film, having a transmittance of less than 5%, preferably less than 2%, and particularly preferably 0%, in the visible spectrum.

[0010] A transparent thermoplastic interlayer may be formed from a first thermoplastic bonding film, and an opaque thermoplastic interlayer may be formed from a second thermoplastic film, wherein the first thermoplastic bonding film is transparent and the second thermoplastic film is opaque. The opaque thermoplastic interlayer may be designed as an opaque thermoplastic film, particularly a polymer film. The term "opaque" indicates insufficient transparency. In the context of this invention, opaque means that an observer cannot see through the interlayer or overlay.

[0011] The transparent thermoplastic interlayer and the opaque thermoplastic interlayer preferably contain at least one plastic, preferably polyvinyl butyral (PVB), ethylene vinyl acetate (EVA) and / or polyethylene terephthalate (PET), or composed thereof.

[0012] The interlayer may also comprise, for example, polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate, polyvinyl chloride, polyacetic acid resin, casting resin, acrylate, fluorinated ethylene-propylene, polyvinyl fluoride and / or ethylene-tetrafluoroethylene, or copolymers or mixtures thereof. The interlayer may be formed from one or more films stacked on top of each other, wherein the film thickness is preferably from 0.025 mm to 1 mm, typically 0.38 mm or 0.76 mm. The interlayer may preferably be thermoplastic and, after lamination, the first glass plate, the second glass plate, and possibly other interlayers are glued together. Particularly advantageous is a so-called acoustic damping interlayer, which preferably consists of three PVB sublayers, wherein the middle sublayer is designed to be softer than the two outer sublayers.

[0013] The interlayer may also have functional layers, particularly layers that reflect infrared radiation, absorb infrared radiation, absorb UV radiation, are at least partially stained, and / or at least partially colored. For example, a thermoplastic interlayer may also be a belt filter.

[0014] The opaque thermoplastic interlayer and the transparent thermoplastic interlayer are preferably composed of polyvinyl butyral. This achieves optimal results and prevents material incompatibility. The transparent thermoplastic interlayer and the opaque thermoplastic interlayer form an interlayer. This results in a continuous interlayer, which is advantageous for a uniform glass sheet geometry. The first bonding film can extend over the entire area of ​​the composite glass sheet, excluding the edge regions. The opaque film extends at least, and preferably only, over the edge regions of the composite glass sheet. Furthermore, the opaque thermoplastic interlayer can extend from the edge of the glass sheet to a notch in which the light source is arranged. The opaque thermoplastic interlayer can extend from the edge of the glass sheet towards the center of the composite glass sheet from 1 mm to 500 mm, preferably 10 mm to 150 mm, and particularly preferably 10 mm to 15 mm.

[0015] In one embodiment, the absorption unit further includes a first covering layer disposed on a first surface (IV) of the first glass plate.

[0016] In another embodiment, the second glass plate has a second cover layer. The first and / or second cover layers are preferably opaque. Furthermore, the opaque thermoplastic interlayer and the first and second cover layers preferably have the same optical density.

[0017] In a particularly preferred embodiment, the second glass plate has a second cover layer. Thus, scattered light in the edge region is absorbed at both main surfaces of the composite glass plate. The first and second cover layers can extend from the edge of the first glass plate by 1 mm to 500 mm, preferably 10 mm to 150 mm, and particularly preferably 10 mm to 15 mm.

[0018] In one embodiment, the opaque thermoplastic interlayer, the first cover layer, and the second cover layer overlap at least partially in the perspective direction of the composite glass plate.

[0019] Preferably, the first cover layer is disposed on the first surface of the first glass plate. In particular, the first cover layer and the second cover layer overlap at least partially in the perspective direction of the composite glass plate.

[0020] The overlay is also called an overlay print or a black print. The overlay print is formed by printing ink. The first and / or second overlay can be formed of opaque enamel, preferably applied as a screen print or digital print. The enamel can contain glass frit and / or mineral frit and optionally at least one pigment, preferably glass frit and / or mineral frit based on oxides selected from boron, bismuth, zinc, silicon, aluminum, and sodium. The pigment provides the opacity of the overlay. The pigment can contain black pigments, such as pigment black (carbon black), aniline black, bone black, iron oxide black, spinel black, and / or graphite. Alternatively, the first and / or second overlay can be designed as tape, particularly black tape, or a base layer, i.e., a so-called primer. The primer can contain a sol-gel layer made of silica mixed with other inorganic oxides.

[0021] Alternatively or additionally, the absorption unit may include another cover layer disposed on the intermediate layer, particularly on an opaque thermoplastic intermediate layer.

[0022] In another embodiment, the composite glass panel includes a surrounding glass panel edge, wherein the absorbing units are arranged at least partially along the surrounding glass panel edge, or the absorbing units extend circumferentially along the entire surrounding glass panel edge. The composite glass panel has a transparent area, wherein the composite glass panel has no covering layer. The transparent area of ​​the composite glass panel occupies at least 30%, preferably 50%, of the area of ​​the composite glass panel. If the composite glass panel is designed as a top glass panel or a windshield panel, the transparent area may occupy at least 70% or at least 80% of the area of ​​the composite glass panel.

[0023] In another embodiment, the light source includes at least one or more light-emitting diodes (LEDs). This type of light source is particularly bright and efficient. The first glass plate has at least one notch for accommodating the light source. This allows for the reduction of light scattered into the external environment of the composite glass plate and improved coupling of light into the first glass plate. Alternatively, the light source may be arranged outside the composite glass plate on a side surface or a first surface (IV) of the first glass plate, such that light is coupled into the first glass plate via the external side surface or first surface (IV).

[0024] In principle, any electrically insulating substrate that is thermally stable, chemically stable, and dimensionally stable under the conditions of manufacture and use of composite glass plates is suitable as the first and second glass plates.

[0025] The first and second glass plates preferably comprise glass, particularly float glass made of clear glass, and very particularly diamond glass. Alternatively, the glass plates may also comprise flat glass, such as soda-lime glass, borosilicate glass, or quartz glass, or clear plastic, rigid clear plastic, especially polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polyamide, polyester, polyvinyl chloride, and / or mixtures thereof. The first and / or second glass plates are preferably transparent, particularly for applications where the glass plates are used as roof panels, windshields, or rear panels of vehicles, or other applications where high light transmittance is required. In particular, at least the first glass plate, and preferably the second glass plate, is composed of clear glass.

[0026] If a coating, glass plate, or object has a transmittance of greater than 20%, preferably 50%, particularly preferably greater than 70%, and especially greater than 85% in the visible spectrum, then the coating, particularly the glass plate, or object is considered transparent.

[0027] However, for glass panels not within the driver's field of vision in traffic-related situations, such as the top glass panel, the transmittance can also be much lower, for example, greater than 5%. In the context of this invention, transparency means that an observer can see through the glass panel or interlayer and identify objects located behind the glass panel or interlayer from the observer's perspective. Furthermore, for example, the second glass panel and / or interlayer can be colored or stained.

[0028] The thickness of the first and / or second glass panes can vary widely, thus adapting well to the requirements of various situations. A standard thickness of 1.0 mm to 25 mm, preferably 1.4 mm to 2.5 mm, is preferred for vehicle glass, while a standard thickness of 4 mm to 25 mm is preferred for furniture, appliances, and buildings. The dimensions of the glass panes can vary widely and depend on the dimensions required for the application according to the invention. The first and second glass panes have a thickness of 200 cm. 2 up to 20m 2 The area is commonly found in fields such as vehicle construction and building.

[0029] The composite glass plate can have any three-dimensional shape. Preferably, the three-dimensional shape has no shaded areas, so it can be coated with a further coating, for example, by cathode sputtering. Preferably, the glass plate is flat or slightly or severely curved in one or more directions in space. In particular, a flat substrate is used. The glass plate can be colorless or stained.

[0030] The terms "first glass panel" and "second glass panel" are chosen to distinguish the two glass panels in the composite glass panel according to the invention. This terminology is not associated with statements regarding geometric arrangement. For example, if the composite glass panel according to the invention is configured to separate interior space from the external environment in an opening, such as in a vehicle or building, the first glass panel may face either the interior space or the external environment.

[0031] In one advantageous embodiment, the composite glass panel is the roof glass panel of a motor vehicle, wherein the first glass panel is the inner glass panel and the second glass panel is the outer glass panel.

[0032] In addition, the first glass plate and / or the second glass plate may have other suitable coatings, such as anti-reflective coatings, anti-stick coatings, anti-scratch coatings, photocatalytic coatings, sun-protective coatings, and / or low-emissivity coatings.

[0033] In addition, the assembly glass device may optionally include other functional elements, particularly electronically controllable optical elements, such as PDLC elements, electrochromic elements, etc., which are typically arranged between the first glass plate and the second glass plate.

[0034] The first and second glass plates are laminated together by an intermediate layer, for example by autoclave method, vacuum bag method, vacuum ring method, calendering method, vacuum laminator or a combination thereof. Here, the glass plates are typically joined under the action of heat, vacuum and / or pressure.

[0035] On the other hand, the present invention includes vehicles having a glass assembly device according to the invention, particularly passenger vehicles.

[0036] In another aspect, the present invention includes a method for manufacturing an assembly glass device according to the invention, comprising at least:

[0037] • A first glass plate, a second glass plate, and a thermoplastic interlayer are provided, wherein the thermoplastic interlayer includes an opaque thermoplastic interlayer as an absorbent unit.

[0038] • The absorption unit is arranged in the edge region.

[0039] • At least one light source is arranged on the first glass plate.

[0040] • An optically coupled output unit is arranged on the first surface (IV) of the first glass plate.

[0041] • The first glass plate and the second glass plate are laminated together via a thermoplastic interlayer such that the second surface (III) of the first glass plate faces the thermoplastic interlayer.

[0042] The opaque thermoplastic interlayer is preferably formed of an opaque thermoplastic film, wherein the thermoplastic interlayer includes an opaque thermoplastic interlayer and a transparent thermoplastic interlayer.

[0043] Opaque thermoplastic interlayers can be laid manually or by machine, such as by a robot. Opaque thermoplastic interlayers, especially opaque thermoplastic films, can be held in place by laminating transparent thermoplastic interlayers.

[0044] If the composite glass panel needs to be bent, especially common for passenger vehicles, the bending process is performed on the glass panel before lamination. Before lamination and optional bending, it is preferable to apply an opaque overlay, particularly to the edge areas of the second glass panel. During the manufacture of the composite glass panel assembly, the overlay is applied by screen printing before bending each glass panel. For this purpose, black or dark enamel is applied by screen printing and fired before lamination, especially before or during bending.

[0045] The invention also includes the use of the glass assembly according to the invention in land, sea and air transportation vehicles, particularly in motor vehicles, for example as a roof glass panel, rear glass panel and / or side glass panel.

[0046] In the context of this invention, all embodiments mentioned for each feature can be freely combined with each other, as long as they do not contradict each other.

[0047] The present invention will now be explained in more detail with reference to the accompanying drawings and embodiments. The drawings are schematic and not drawn to scale. The drawings do not limit the invention in any way.

[0049] Figure 1 A top view of an embodiment of the composite glass panel according to the present invention is shown, taking the top glass panel of a vehicle as an example.

[0050] Figure 2 A schematic cross-sectional view of a first embodiment of the glass assembly apparatus according to the present invention is shown, and

[0051] Figure 3 A schematic cross-sectional view of a second embodiment of the glass assembly apparatus according to the present invention is shown.

[0052] Numerical descriptions are not usually interpreted as precise values, but rather include tolerances of + / -1% to + / -10%.

[0053] Figure 1A top view of an embodiment of a glass assembly 10 having a composite glass panel 101 according to the present invention is shown, taking the roof glass panel of a vehicle as an example. Alternatively, the composite glass panel 101 may be architectural glass or a component of furniture or electrical equipment. The glass assembly 10 may also be part of insulated glass and used as, for example, an outer or inner glass panel in a building window. Furthermore, the glass assembly 10 may be installed in an interior space and may be used as, for example, glass in a conference room.

[0054] The glass assembly 10 includes a composite glass plate 101 and two light sources 2. The light sources 2 are configured to emit light in the visible range. Alternatively, they may emit infrared or ultraviolet light. Each light source 2 of the glass assembly 10 may be one or more light-emitting diodes (LEDs, LED modules, LED lamps). The light sources 2 may also include organic light-emitting diodes (OLEDs).

[0055] The composite glass plate 101 also has four optical coupling output units 4. The optical coupling output units 4 couple light out of the composite glass plate 101. The optical coupling output units 4 are arranged on the first surface IV (the main surface of the composite glass plate 101). At the location where the optical coupling output units 4 are arranged, light can leave the composite glass plate 101 via surface IV.

[0056] The optically coupled output unit 4 can be arranged at any arbitrary location on surface IV. Figure 1 In this embodiment, the optical coupling output unit 4 includes a structured surface IV, which prevents total internal reflection within the composite glass plate 101 and allows light to exit from the composite glass plate 101 via the surface IV. Alternatively, the optical coupling output unit 4 may include printing on the surface IV or particles or cavities introduced into the composite glass plate 101 for light scattering, refraction, diffraction, or reflection.

[0057] In this embodiment, the light-coupled output unit 4 is also formed on surface IV as a print made of fine light-scattering particles. This interrupts total internal reflection of the light beam at the interface between the composite glass plate 101 and the surrounding air, and the light is coupled out from the composite glass plate 101 by scattering.

[0058] The composite glass plate 101 has an absorption unit 8 in the edge region 7 for absorbing light 3 coupled into the composite glass plate 101. The composite glass plate 101 includes a surrounding glass plate edge 12, wherein the absorption unit 8 extends circumferentially along the entire surrounding glass plate edge 12. Alternatively, the absorption unit 8 may be arranged at least partially along the surrounding glass plate edge 12. The width of the edge region 7 is measured from the glass edge 12 and is, for example, 10 mm, 50 mm, or 100 mm.

[0059] Surprisingly, it has been shown that the arrangement of the absorption units 8 in the edge region 7 of the composite glass panel 101 is particularly effective in preventing scattered light at the edge 12 of the glass panel. This is especially advantageous for glass panels where the edge region is not covered in the installed state. Due to the absorption units 8, the exposed edge is darkened and therefore the illumination pattern (e.g., stars) formed by the light-coupled output units 4 is well-recognized.

[0060] The composite glass panel 101 has a transparent area 15 in which the composite glass panel has no covering layer. The transparent area 15 of the composite glass panel 101 occupies, for example, at least 70% of the area of ​​the composite glass panel 101.

[0061] Figure 2 Showing Figure 1 The cross-sectional view of the glass assembly apparatus 10 according to the present invention is shown. The composite glass plate 101 includes a first glass plate 1, which is bonded to a second glass plate 6 via an intermediate layer 5. The first glass plate 1, the intermediate layer 5, and the second glass plate 6 are bonded to each other by lamination, particularly by autoclave processing. The second glass plate 6 has a first surface I and a second surface II opposite to the first surface I.

[0062] The first glass plate 1 has a first surface IV and a second surface III opposite to the first surface IV. The end faces of the composite glass plate 101 are arranged orthogonally to surfaces III and IV. The first glass plate 1 and the second glass plate 6 are made of, for example, soda-lime glass. The thermoplastic interlayer 5 is formed of, for example, a 0.76 mm thick PVB film. The thickness of the first glass plate 1 is, for example, 1.6 mm, and the thickness of the second glass plate 6 may be 2.1 mm. The first glass plate 1 and the second glass plate 6 may have any thickness, for example, even the same thickness. The composite glass plate 101 is defined by four surrounding side surfaces.

[0063] The first glass plate 1 may comprise prestressed, partially prestressed, or unstressed glass. Alternatively, the first glass plate 1 may be made of plastic, such as polycarbonate. The first glass plate 1, the second glass plate 6, and the intermediate layer 5 are, for example, transparent (neither colored nor stained). Alternatively or additionally, the second glass plate 6 may be darkly stained.

[0064] The first glass plate 1 has a notch 13 into which one of the two light sources 2 is inserted. The notch 13 extends continuously from the first surface IV of the first glass plate 1 to the second surface III of the first glass plate 1. The intermediate layer 5 is not removed in the area of ​​the notch 13. The light source 2 is entirely located within the composite glass plate 101. The light 3 emitted by the light source 2 is directed towards the glass plate 1. The glass plate 1 is configured to further conduct the coupled-input light 3 longitudinally. The first glass plate 1 is preferably the inner glass plate and the second glass plate 6 is the outer glass plate. In the installation position, the inner glass plate faces the interior space. In the installation position, the outer glass plate faces the external environment (e.g., the external environment of the vehicle). This arrangement is particularly advantageous due to the positioning of the light source 2 within the first glass plate 1, as the coupled output of light occurs towards the interior space (of the vehicle), resulting in a comfortable atmosphere within the interior space. Alternatively, the second glass plate 6 may also be the inner glass plate and the first glass plate 1 the outer glass plate.

[0065] Intermediate layer 5 includes a transparent thermoplastic intermediate layer 5.1 and an opaque thermoplastic intermediate layer 5.2. The transparent thermoplastic intermediate layer 5.1 is designed as a first thermoplastic bonding film, and the opaque thermoplastic intermediate layer 5.2 is designed as a second thermoplastic film. The first thermoplastic bonding film is transparent and the second thermoplastic film is opaque.

[0066] An opaque thermoplastic interlayer 5.2 extends approximately 10 mm, 50 mm, or 100 mm from the edge 12 of the glass plate towards the center of the composite glass plate 101. The opaque thermoplastic interlayer 5.2 is arranged along the edge 12 of the glass plate.

[0067] exist Figure 2 In the illustrated embodiment, the absorbing unit 8 includes an opaque interlayer 5.2, a first capping layer 9, and a second capping layer 11. The first capping layer 9 is applied to a first surface IV of the first glass plate 1. The second capping layer 11 is applied to a surface II of the second glass plate 6. Since light coupling and output at the edges of the composite glass plate are undesirable, the edge region 7 of the first glass plate 1 has the opaque interlayer 5.2, the first capping layer 9, and the second capping layer 11, which absorb scattered light. Thus, scattered light in the edge region 7 of the composite glass plate 101 is prevented with minimal complexity.

[0068] The second cover layer 11 is disposed on the second surface II of the second glass plate 6. Specifically, the opaque thermoplastic interlayer 5.2 and the second cover layer 11 overlap in the perspective direction of the composite glass plate 101. The light source 2 is obscured by the second cover layer 11 in the perspective direction. The second cover layer 11 is peripheral, i.e., a frame-like cover print. The second cover layer 11 surrounds the perspective area 15. Both the first cover layer 9 and the second cover layer 11 are designed to be opaque and continuous.

[0069] The first coating layer 9 and the second coating layer 11 comprise pigments and glass frit. They may contain other compounds. The glass frit may be partially melted or fused, thereby permanently bonding (fusing or sintering) the coating layers 9 and 11 to the glass surface. The pigments ensure the opacity of the coating layers 9 and 11. Such coating layers are applied as enamel.

[0070] Figure 3 A schematic cross-sectional view of a second embodiment of the glass assembly apparatus 10 according to the present invention is shown. Figure 3 The glass assembly 10 shown is particularly well-suited as a roof glass panel for motor vehicles. Figure 3 The glass assembly device 10 has a connection with Figure 2 The assembly glass device 10 has a similar structure. The second glass plate 6 (outer glass plate) is similar to... Figure 2 The glass plate 6 is the same. However, it is different from... Figure 2 Unlike the first overlay layer 9, Figure 3 The frame is applied in a frame-like manner to the first surface IV of the first glass plate 1.

[0071] The first glass plate 1 is, for example, positioned to face the interior space of the vehicle in the installation position. Therefore, the first surface IV of the first glass plate 1 is accessible from the interior space, while the first surface I of the second glass plate 6 points outward relative to the interior space of the vehicle.
