Definitions

  • 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.
  • the recesses are usually arranged in one of the two glass panes of a composite pane and are hidden by an opaque imprint when looking at the other of the two glass panes. Depending on the opacity of this imprint, the light source is visible when looking at the other pane of glass and a slightly brighter ring of light appears around the point at which the light is coupled into the pane. This should be avoided for aesthetic reasons.
  • DE 102017 103296 A1 discloses a pane arrangement with an illumination device.
  • the lighting device is attached to the disc body and includes a light source and a light guide layer that is attached to the disc body.
  • Glazing with an LED arranged in a recess is known from WO 2018/178591 A1.
  • the glazing includes a light guide element.
  • the object of the present invention is to provide an improved glazing assembly that has high efficiency and increased reliability.
  • the glazing assembly of the present invention includes a first pane having a first major surface and a second major surface.
  • the first pane is connected to a second pane via an intermediate layer to form a composite pane.
  • the first pane is provided for the purpose of at least partially forwarding coupled-in light.
  • the glazing arrangement comprises a light source for generating light that can be coupled into the first pane, which light source is arranged in a recess in the first pane.
  • the glazing arrangement comprises a cover for the recess and a filling material in the recess which is transparent to the optical radiation of the light source.
  • the filling material is formed from a hard, soft, deformable, gel-like and/or liquid material.
  • the recess can be filled with a form fit by the deformable material, so that no disturbing scattered light can escape.
  • the filling material can include, for example, silicone or resin, in particular synthetic resin.
  • the filling material in the recess can have a refractive index of 1.45 to 1.55.
  • the refractive index of the filling material is selected in such a way that total reflection at the interfaces between the filling material and the first pane is avoided.
  • the refractive index of the filling material np and the refractive index of the first pane ns are selected such that np s ns applies.
  • the filling material particularly advantageously has a refractive index similar to that of glass.
  • refractive indices are generally given in relation to a wavelength of 550 nm.
  • the refractive index is basically independent of the measuring method, it can be determined, for example, by means of ellipsometry. Ellipsometers are commercially available. When determining the refractive index of the filling material, the same measuring method is used as when determining the refractive index of the first pane.
  • the filler material is transparent.
  • the light can be coupled particularly effectively into the first pane.
  • the filling material is additionally arranged around the recess on the first main surface of the first pane.
  • the filling material can protrude by about 2 mm to 50 mm, preferably 5 mm to 30 mm.
  • the filling material serves to embed the light guide with the light source in the recess. This improves the coupling of the light emitted from the light source into the first pane.
  • the glazing arrangement achieves high efficiency and increased reliability, since the resulting light emerging from the light guide enters the first pane in a targeted manner.
  • the cover prevents moisture or components from the intermediate layer from diffusing into the recess.
  • the cover is preferably designed as a metal foil or a metalized plastic foil. Metal foils reflect well and can effectively direct the light emitted in the area of the light source back into the first pane.
  • the metal foil is preferably an aluminum foil. It goes without saying that 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 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.
  • the second pane is provided on its second main surface with a transparent functional coating that includes electrically conductive layers.
  • the transparent functional coating is preferably a sun protection coating.
  • Sun protection coatings reflect parts of the sun's radiation in the near infrared spectrum and prevent it from penetrating into the vehicle interior and heating it up. They typically have one or more silver layers, which provide the IR-reflecting properties, as known, for example, from WO2013/104439A1 and from DE 19927683C1. Therefore, these layers are arranged on the side of the second pane facing the thermoplastic intermediate layer in order to protect it from corrosion and mechanical damage.
  • the first pane is provided with a Low-E coating on its first main surface.
  • Low-E coatings are emissivity-reducing coatings and reflect IR radiation, especially thermal radiation, which emanates from a heated pane of glass. The penetration of thermal radiation into the vehicle interior is reduced, which also causes the interior to heat up less. In winter, when outside temperatures are low, the heat from the interior is prevented from radiating to the outside environment.
  • Transparent emissivity-reducing coatings can contain, for example, reflective layers based on indium tin oxide (ITO) or other transparent conductive oxides (TCO), as known, for example, from WO2013/131667A1.
  • the low-E coating preferably does not contain any silver layers and can therefore be arranged on the first main surface of the first pane without problems with corrosion.
  • a functional coating with electrically conductive layers, in particular silver layers is arranged on the second main surface of the second pane.
  • the opaque masking print is arranged in the edge area of the functional coating. That means the opaque masking print is printed directly onto the functional coating.
  • the cover print is preferably formed from a printing ink that has decomposing properties compared to the functional coating.
  • the advantages of the invention are particularly evident, since a masking print formed in this way often cannot sufficiently mask the light source when it is switched on.
  • An additional measure, namely the shielding element according to the invention is an excellent solution here.
  • 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.
  • a further aspect of the invention comprises the glazing arrangement according to the invention, comprising a voltage source and control electronics which are connected to the light source.
  • the light source can be controlled by the voltage source and control electronics so that it emits light when a voltage is applied to the light source.
  • the present invention includes vehicles, in particular passenger cars, with a glazing arrangement according to the invention.
  • the present invention comprises a method for producing a glazing arrangement according to the invention, at least comprising:
  • a light guide is arranged in the recess together with the light source.
  • the light source and the light guide can be designed as a structural unit, in particular a module.
  • the structural unit can have an LED circuit board which includes one or more LEDs.
  • FIG. 1 shows a top view of an embodiment of a composite pane according to the invention using the example of a roof pane of a vehicle
  • FIG. 1 shows a plan view of an embodiment of a glazing arrangement 10 according to the invention.
  • the glazing arrangement 10 comprises a laminated pane 101 and at least one structural unit 5.
  • the glazing arrangement 10 can be a roof pane for a vehicle, for example.
  • the glazing assembly 10 may be architectural glazing or a component of furniture or electrical equipment.
  • 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.
  • the glazing arrangement 10 can be installed in an interior space and can be used, for example, as glazing for a conference room.
  • the glazing arrangement 10 comprises the laminated pane 101 and two structural units 5, each with a light source 5.1.
  • the light sources 5.1 are intended to emit light in the visible range. Alternatively, they can emit infrared or ultraviolet light.
  • the light extraction means 11 is designed as an imprint of fine, light-scattering particles on the main 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.
  • FIG. 2 shows a cross-sectional illustration of the glazing arrangement 10 according to the invention from FIG.
  • the first disc 1 , the Intermediate layer 3 and the second pane 6 were connected to one another by lamination, in particular in an autoclave.
  • the first pane 1 has a first main surface IV and a second main surface III opposite the first main surface IV.
  • the second pane 2 has a first main surface I and a second main surface II opposite the first main surface I .
  • the side surfaces of the laminated pane 101 are arranged orthogonally to the main surfaces III, IV.
  • the first pane 1 and the second pane 2 consist, for example, of soda-lime glass.
  • the intermediate layer 3 is thermoplastic and formed, for example, from a 0.76 mm thick PVB film.
  • the thickness of the first pane 1 is 1.6 mm, for example, and the thickness of the second pane 2 is 2.1 mm.
  • the compound pane 101 is delimited by four circumferential side surfaces.
  • the first pane 1 can comprise toughened, partially toughened or non-toughened glass.
  • the first pane 1 can be made of a plastic, for example made of polycarbonate.
  • the first pane 1, the second pane 2 and the intermediate layer can comprise toughened, partially toughened or non-toughened glass.
  • the first pane 1 can be made of a plastic, for example made of polycarbonate.
  • the structural unit 5 includes the light sources 5.1 and a light guide 5.2.
  • the structural unit 5 can be a so-called LED module.
  • the intermediate layer 3 was not removed in the area of the cutout 9 .
  • the light source 5.1 is located entirely within the laminated pane 101.
  • the light source 5.1 is preferably an LED.
  • the light source 5.1 can have one or more Light emitting diodes (LED, LED light) include.
  • a light source 5.1 can also include an organic light-emitting diode (OLED).
  • the light emitted by the light source 5.1 is directed in the direction of the pane 1 and reaches the first pane 1 via the light guide 5.2.
  • the pane 1 is intended to forward the coupled-in light through the pane 1 in the longitudinal direction.
  • the first pane 1 is preferably an inner pane and the second pane 2 is an outer pane.
  • the inner pane faces an interior space.
  • the outer pane faces the outside environment (e.g. of a vehicle).
  • This arrangement is particularly advantageous because of the position of the light sources 5.1 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.
  • the second pane 2 can also represent the inner pane and the first pane 1 the outer pane.
  • a first cover layer 4 and a second cover layer 4 are applied to the first main surface IV of the first pane 1 and to the second main surface II of the second pane 2 .
  • the covering layers 4 are opaque, dark, in particular black or grey.
  • the covering layer 4 is formed from a printing ink. Since it is not desirable for light to be coupled out at the edges of the composite pane 101 , the edge region 16 of the first pane 1 has the covering layer 4 .
  • the second opaque, dark, in particular black or gray black covering layer 4 is arranged on the second main surface II of the second pane 2 .
  • the first covering layer 4 and the second covering layer 4 overlap in the viewing direction of the laminated pane 101.
  • the recess 9 is covered by the second covering layer 4 in the viewing direction.
  • the first and second cover layers 4 are peripheral, i.e. frame-like, cover prints.
