  • the light source is arranged in a recess of the intermediate layer.
  • the light source can be arranged directly between the outer pane and the inner pane and thus emit the light particularly clearly and clearly for the driver.
  • the light source is an active self-illuminating light source such as a light emitting diode (LED), organic light emitting diode (OLED) and / or an LCD screen.
  • LED light emitting diode
  • OLED organic light emitting diode
  • LCD screen an LCD screen.
  • the special advantage of the light-emitting diodes and the LCD screen lies in the small dimensions and intense luminosity. Both the LEDs and the LCD screen are characterized by a very low energy consumption and long life.
  • the intermediate layer is preferably transparent.
  • the intermediate layer preferably contains 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-propylenes, polyvinyl fluoride and / or ethylene-tetrafluoroethylene , or copolymers or mixtures thereof.
  • the intermediate layer can be formed by one or more films arranged one above 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 layer may preferably be thermoplastic and, after lamination, bond the inner pane, the outer pane and any further intermediate layers to one another. For the purposes of the invention, the lamination is thus the joining of inner pane, intermediate layer and outer pane.
  • the production of the composite pane by lamination takes place with, for example, vacuum bag methods, vacuum ring methods, calendering methods, vacuum laminators, autoclave methods or combinations thereof.
  • the connection between outer pane and inner pane is usually carried out under the action of heat, vacuum and / or pressure. Due to the lamination of the light source in the intermediate layer of the composite pane, the production of the composite pane according to the invention is comparatively inexpensive and cost-effective.
  • the composite pane is suitable for separating a vehicle interior from an external environment.
  • the composite pane can be used in many ways. It may be, for example, a windshield, a roof window, a rear window, a side window or another glazing bounding the vehicle interior.
  • the display device is arranged in the middle upper section of the composite pane.
  • the Display device may be arranged at the lower left edge of the composite disc.
  • the display device can be connected via a flexible film conductor (flat conductor, ribbon conductor), a metallic wire, in particular a round conductor or a stranded conductor with a voltage source and a signal line, which forwards the control signal of the control device in a vehicle via a CAN bus.
  • a foil conductor is, for example, a strip or band containing or consisting of copper, tinned copper, aluminum, silver, gold or alloys thereof.
  • the film conductor has, for example, a width of 2 mm to 16 mm and a thickness of 0.03 mm to 0.1 mm.
  • the foil conductor can have an insulating, preferably polymeric sheath, for example based on polyimide. Alternatively, thin metal wires can be used as an electrical connection.
  • the composite pane or the inner pane and the outer pane preferably contain glass, particularly preferably flat glass, float glass, quartz glass, borosilicate glass, soda-lime glass, or clear plastics, preferably rigid clear plastics, in particular polyethylene, polypropylene, polycarbonate, polymethyl methacrylate, polystyrene, polyamide , Polyester, polyvinyl chloride and / or mixtures thereof.
  • the composite pane or the inner pane and the outer pane are preferably transparent, in particular for the use of the pane as a windshield of a vehicle or other uses in which a high light transmission is desired.
  • a disc having a transmission in the visible spectral range of greater than 70% As transparent in the context of the invention is then understood a disc having a transmission in the visible spectral range of greater than 70%. For discs that are not in the traffic-related field of view of the driver, for example, for roof windows, but the transmission can also be much less, for example, greater than 5%.
  • the outer pane and the inner pane preferably have a constant thickness with essentially plane-parallel main surfaces and a peripheral side edge connecting them.
  • the thickness of the inner pane is in an advantageous embodiment of 0.4 mm to 3.5 mm, preferably from 0.9 mm to 2.1 mm.
  • the thickness of the outer pane is in an advantageous embodiment at least 1.4 mm, preferably at least 1.6 mm.
  • the thickness of the outer pane is preferably at most 4.5 mm, preferably at most 2.1 mm.
  • the composite disk has a favorable mechanical stability and noise-shielding Properties on, but is still sufficiently thin and light to be used as a windshield can.
  • the outer pane and inner pane are not provided with a bias. Nevertheless, during the lamination of the panes, a characteristic distribution of tensile and compressive stresses forms, which, however, can easily be distinguished by a person skilled in the art from stresses that are deliberately generated by the use of prestressed panes.
  • the outer pane, the inner pane and the thermoplastic intermediate layer can be clear and colorless, but also tinted or colored.
  • the total transmission through the composite pane in a preferred embodiment is greater than 70%, especially if the composite pane is a windshield.
  • the term total transmission refers to the procedure defined by ECE-R 43, Annex 3, ⁇ 9.1 for testing the light transmission of vehicle windows.
  • the composite panel is preferably bent in one or more directions of the space, as is conventional for automotive windows, with typical radii of curvature ranging from about 10 cm to about 40 m.
  • the composite pane can also be flat, for example, if it is intended as a disc for buses, trains or tractors.
  • the wedge angle of the intermediate layer can be constant in the vertical course, resulting in a linear change in thickness of the intermediate layer, wherein the thickness is typically larger from bottom to top.
  • the direction "from bottom to top” designates the direction from bottom edge to top edge, ie the vertical curve, but there may also be more complex thickness profiles in which the wedge angle is variable from bottom to top (that is location-dependent in the vertical course), linear or non-linear.
  • the thickness of the intermediate layer increases in the vertical course from bottom to top at least in sections.
  • the thickness of the intermediate layer may be constant in horizontal sections (that is to say sections approximately parallel to the top edge and bottom edge). Then the thickness profile across the width of the composite disc is constant. The thickness can also be variable in horizontal sections. Then the thickness is variable not only in the vertical but also in the horizontal course.
  • the intermediate layer is formed by at least one thermoplastic film.
  • the wedge angle can be produced by suitable extrusion of the film or by stretching a film with a constant thickness in the initial state.
  • the intermediate layer may be formed by a single film or by more than one film. In the latter case, at least one of the films must be formed with the wedge angle.
  • the intermediate layer can also be formed from a so-called acoustic film, which has a noise-damping effect. Such films typically consist of at least three layers, the middle layer having a higher plasticity or elasticity than the surrounding outer layers, for example due to a higher proportion of plasticizers.
  • the intermediate layer preferably has a minimum thickness of 0.4 mm to 1, 5 mm, more preferably from 0.5 mm to 1, 0 mm.
  • Minimum thickness refers to the thickness at the thinnest point of the intermediate layer, typically the thickness at the bottom edge of the composite disk. Laminated discs with thinner intermediate layers often have too low a stability to be used as a vehicle window can.
  • Another aspect of the invention comprises a method for detecting status information of a control system, in particular a traffic light, wherein
  • a receiving device of a motor vehicle a state information of
  • Control system detected by means of a light-optical signal or radio signal and forwards to a control unit
  • the status information is received by a control unit of the motor vehicle and a control signal for the reproduction of the status information is sent to a light source, wherein the light source in the composite pane between a
