Description

 COMPOSITE COMPONENT WITH LUMINOUS DIODES AND METHOD FOR THE PRODUCTION THEREOF

The present invention relates to a composite component comprising two plastic layers, at least one of which is transparent or translucent, and arranged therebetween at least one light emitting diode and at least two electrical conductors, a method for producing such a composite component and its use as lighting, information, Information, communication or signaling element, in particular in the interior or exterior of buildings and in air, water and land vehicles.

The arrangement of light-emitting diodes (LEDs) between two mineral glass panes for the production of transparent elements with individual light points generated by the light-emitting diodes is known for various fields of application, such as the interior and exterior of buildings. Thus, EP 1 346 822 A1 describes a Gebäudedachverbundglaselement, which is composed of two transparent glass panes and an intermediate connection layer. The bonding layer consists of a cast resin layer or a laminated safety glass (VSG) - plastic film with embedded LEDs. The power is supplied via a cable embedded in the connection layer or alternatively via one or more transparent, electrically conductive layers.

Furthermore, in the prior art a flat glass sheet composite is known in which light-emitting diodes are arranged between a base glass pane and a cover glass pane, which are held together by a polyvinyl butyral (PVB) film. The light-emitting diodes are located on the base glass pane and are preferably supplied with low-voltage direct current via substantially invisible conductor tracks on the base glass pane, as a result of which the light-emitting diodes appear to float freely in the glass. Such a flat glass sheet composite can be used inter alia to obtain desired atmospheric lighting effects. With a suitable arrangement of several light emitting diodes, information, e.g. Symbols or fonts, and in the targeted control of the LEDs and marquees are displayed.

However, the known transparent LED laminated glass elements with light-emitting diodes arranged between two mineral glass panes have a number of disadvantages on, whereby certain applications, in particular the use in the aviation industry, are not possible or only to a very limited extent. Thus, the conventional LED laminated glass elements often have too high a weight due to the mineral glass panes used for the specific application. Furthermore, when using mineral glass, especially if no special safety glass is used, there is an increased risk of injury due to the fragments produced in the event of a break. Mineral glass is also limited or deformable, so far mostly worked with flat glass plates (flat glass). This complicates or prevents the use of LED flat glass composite elements for applications in which a non-planar shape is desired. Furthermore, the processing of mineral glass can be difficult, which can result in increased costs.

The present invention is therefore based on the object to provide a transparent or translucent component with at least one integrated light-emitting diode, which has a low weight, can take various forms, can be produced in a simple manner and is suitable for use in the interior or exterior of Buildings and in air, water and land vehicles.

This object is achieved by the technical teaching specified in claims 1, 16, 23 and 24. Advantageous embodiments will be apparent from the dependent claims.

Accordingly, a first subject of the present invention is a composite component which comprises two plastic layers, at least one of which is transparent or translucent, and an intermediate layer, which is preferably transparent or translucent, between the plastic layers, the intermediate layer comprising at least one light-emitting diode and at least two electrical conductors which are part of a circuit comprises. The intermediate layer is in contact with the inner surfaces of the two plastic layers, so that the two plastic layers are connected to one another via the intermediate layer.

The composite component according to the invention has a significantly lower weight due to the use of plastic instead of glass. Furthermore, the processing properties of usable in the context of the present invention

Plastics significantly better compared to glass. In particular, the plastic used in the present invention can be easily in almost any shapes are reshaped. The composite component according to the invention can therefore be produced in principle in any shape and dimension and is therefore not limited to planar embodiments. Moreover, a coloring or coating of thermoplastics, a preferably used plastic, in a simple manner possible. Due to the freely selectable dimensions of the composite component according to the invention, the possibility of disposing of the light-emitting diodes and the preferably invisible power lines, the composite component according to the invention can be used in various ways in the interior or exterior of buildings and in air, water and land vehicles, for example as lighting, information , Reference, communication or signaling element.

According to the present invention, at least one of the plastic layers of a transparent or translucent plastic layer, wherein the non-transparent or translucent layer may be opaque or reflective and is usually used for the back of the composite component according to the invention. If no transformation is required, the transparent or translucent plastic layer can consist of non-thermoplastic, transparent or translucent plastics, such as thermoset semifinished products or duroplastic molding compositions or transparent prepregs, in particular castable transparent polyurethane. Preferably, however, deformable transparent or translucent plastics, in particular transparent or translucent thermoplastics, are used. These preferably meet the stringent fire safety and safety requirements prescribed for the particular application, such as the fire requirements for cabin components of civil aviation.

Suitable transparent or translucent thermoplastics include PPSU, PEI, PSU, PC, PMMA, PET and PS. In particular, for aircraft applications, PPSU, PEI and PC plastics modified with fire-retardant additives are preferably used which fulfill the fire requirements of the FAA and the Airbus internal requirement according to ABD 0031.

A particularly preferred transparent or translucent thermoplastic in the context of the present invention is a polyphenylsulfone (PPSU) thermoplastic. An example of this is the EUROPLEX® PPSU material marketed by Röhm GmbH, Darmstadt, which is approved for aviation. In principle, however, it is also possible to use other transparent or translucent thermoplastics known in the prior art, provided that they have the same properties as those of the prior art Process conditions, in particular the high temperatures that occur in the production of the composite component according to the invention, are resistant, are not attacked by any adhesives used and external influences, such as temperature, media, mechanical stress, UV light, etc., in the respective 5 adequate use.

The degree of transparency or translucency of a plastic depends on the respective specifications. If, for example, points of light are to be perceived individually and sharply, a clear, transparent, as colorless plastic as possible should be selected.

It is also possible to color the plastic layers used by measures known to a person skilled in the art. This makes it possible to achieve colorful appearances as well as more diffuse impressions through opaque material formulations. Here, the i5 variety of available plastics represents a distinct advantage over glass.

As used herein, the term "transparent" refers to the property of a material to be transparent, i. to transmit electromagnetic radiation in the visible range. Transparent or transparent is a material in general then,

20 when an object located behind the material is clearly visible. For example, clear window glass is transparent. In contrast, the term "translucent" as used herein refers to the property of a material to be partially translucent In a translucent or partially transmissive material, an object located behind the material is not clear but more or less blurred or diffusely discernible A transparent or translucent layer in the sense of the present invention comprises layers that are completely transparent or translucent or due to the presence of non-transparent or translucent elements, such as light-emitting diodes , in essential o areas are transparent or translucent.

As used herein, the term "layer" refers to a planar expanded unitary material that may be over, under, or between others. The term "layer" in this case does not imply any particular thickness and as such does not disclose the material of which the layer is composed and / or its properties, such as flexibility, deformability, etc. A "layer" in the sense of the present invention may have any extension or shape. In addition to the described two plastic layers, the composite component according to the invention may also have further layers located on at least one of its outer sides, such as lacquer layers, color layers, further plastic layers of the above-defined materials, etc., the resulting composite component having at least partial regions that are transparent or translucent are and in which at least one light emitting diode is arranged.

The thickness of the layers present in the composite component according to the invention results from the materials used, their properties and the intended use of the composite component according to the invention. The thicknesses of the at least two plastic layers, which may be the same or different, depend, for example, on the required property, such as stability, optical effect to be achieved, light transmission, etc.

As the light source, at least one light-emitting diode is used in the present invention, since light-emitting diodes consume little energy, are insensitive to vibrations, have a long life and, in particular, generate little heat. Commercially available LEDs which emit white light or a light in one color, such as, for example, blue, green, red, yellow and mixed colors and pastel shades, can be used as light-emitting diodes in the present invention. Suitable for use in the present invention are also light-emitting diodes with changeable light colors. The light-emitting diodes which can be used within the scope of the present invention can also emit light in one or more directions, for example in opposite directions.

Any number of light-emitting diodes in any arrangement can be used in the present invention. The arrangement of the light-emitting diodes can be selected, for example, such that geometric patterns, such as "grids", circles, lines and other geometric arrangements, as well as irregular patterns, such as a starry sky, for lighting or aesthetic purposes, or symbols, pictograms, fonts, etc., as information, information, communication or signal element Furthermore, the light-emitting diodes can also be selectively controlled, whereby, for example, marquees can be generated.

The at least one light-emitting diode is supplied with power via at least two electrical conductors which, together with the at least one light-emitting diode, form part of a light-emitting diode Circuit are. As the "electrical conductor" according to the present invention is generally referred to a material that can conduct electricity. The electrical conductors according to the present invention are either transparent or visible. Preferably, the at least two electrical conductors are transparent, since transparent conductors do not disturb the overall aesthetic impression of the composite component.

Examples of electrical conductors which can be used in the composite component according to the invention are cables, wires, transparent or visible conductive thin layers, transparent or visible conductor tracks, etc. According to the present invention, the power supply is preferably low-voltage current, in particular a low-voltage direct current, for example 12 V DC, 24 V. DC or 48 V DC, used.

According to a preferred embodiment of the present invention, the at least two electrical conductors are designed in the form of conductor tracks. "Conductor tracks" in the context of the present invention are narrow and thin electrically conductive layers which are applied to a given substrate by a method known in the art, such as vapor deposition, spraying, vaporization or sputtering. These electrically conductive layers may consist of a metal, a metal alloy or a metal oxide.

A particularly preferred electrical conductor for use in the present invention is a transparent conductor made of a transparent, conductive metal oxide. The transparent, conductive metal oxide is preferably indium tin oxide (UO), indium-doped zinc oxide, aluminum-doped zinc oxide, antimony-doped tin oxide or fluorine-doped tin oxide. Particularly suitable in the context of the present invention is indium tin oxide.

The at least two electrical conductors and the at least one light-emitting diode of the conductor and light-emitting diode arrangement can be arranged in different ways in the intermediate layer located between the two plastic layers. Thus, according to a preferred embodiment, the at least one light-emitting diode and the at least two electrical conductors of the conductor and light-emitting diode arrangement are applied directly to one of the inner surfaces of the two plastic layers. The term "direct" in this context means that at least a part of at least one conductor and / or at least one light-emitting diode is in direct contact with one of the inner surfaces of the plastic layers. Alternatively, one or more conductors may also run directly on the inner surface of one of the two plastic layers and one or more other conductors may run directly on the inner surface of the other of the two plastic layers. It is conceivable, for example, that the conductors which serve to direct the current to the light-emitting diodes run directly on the inner surface of one of the two plastic layers, while the conductors which serve to return the current run directly on the inner surface of the other of the two plastic layers , The light-emitting diodes can be arranged either on one, the other or both inner surfaces of the two plastic layers. Mixed forms of these arrangements are conceivable.

In another preferred embodiment of the composite component according to the invention, the at least two electrical conductors and the at least one light-emitting diode of the conductor and light-emitting diode arrangement are arranged so that the electrical conductors in the interior of the intermediate layer, i. without direct contact with the inner surfaces of the two plastic layers, and also the LEDs are embedded in the intermediate layer, without direct contact with the inner surfaces of the plastic layers.

In a particularly preferred embodiment of the composite component according to the invention, a light-emitting diode (LED) film is used as a conductor and light-emitting diode arrangement. This consists of a transparent or translucent, non-conductive plastic substrate and at least two electrical conductors and at least one light emitting diode. The at least two electrical conductors and the at least one light-emitting diode are arranged on the transparent or translucent, non-conductive plastic substrate and form part of a circuit. The transparent or translucent, non-conductive plastic substrate is preferably a film of a transparent or translucent plastic, such as, for example, polyethylene terephthalate (PET). The electrical conductors and the light-emitting diodes are as defined above, wherein as electrical conductors preferably transparent conductor tracks are used, which consist for example of a transparent, conductive metal oxide described above. The light-emitting diode foil is preferably arranged in the interior of the intermediate layer and embedded in it, i. is not in direct contact with the inner surfaces of the two plastic layers.

The two plastic layers of the composite component according to the invention can be connected to one another via mechanical fastening means, such as clamps, clamps, etc. be his. In this case, the intermediate layer can contain spacers, which are preferably transparent or translucent and consist, for example, of an aforementioned thermoplastic material, and / or other transparent or translucent substances, such as fillers, and / or air, and / or other materials Plastic layers on the preferably transparent or translucent intermediate layer releasably connect to each other.

However, the intermediate layer preferably comprises at least one adhesive layer, which ensures that the two plastic layers are firmly connected to one another via the intermediate layer and / or the plastic layers maintain a required or desired distance from one another. Since the intermediate layer is preferably transparent or translucent, the at least one adhesive layer is preferably also made of a transparent or translucent material. The number and arrangement of the adhesive layers depends inter alia on the structure and arrangement of the conductor and light-emitting diode arrangement. Thus, for example, when using a light-emitting diode foil arranged in the middle of the intermediate layer, there is usually an adhesive layer above and below the light-emitting diode foil which connects the light-emitting diode foil to the inner surfaces of the two plastic layers.

The adhesive layer or the adhesive layers of the composite component according to the invention usually consists or consist of a casting resin or a hotmelt adhesive. Suitable casting resins are known to a person skilled in the art and include, for example, epoxy, polyester and polyurethane resins. Preferred hot melt adhesives are polyvinyl butyral (PVB), ethyl vinyl acetate (EVA) and thermoplastic polyurethanes (TPU). These hot-melt adhesives are commercially available usually in the form of films which can be placed between the plastic layers and produce a compound upon heating on cooling. The use of multiple layers of these adhesive films and / or different thickness adhesive films allows the production of adhesive layers of different thicknesses. The adhesive layers are preferably so thick that they preferably completely surround the light-emitting diode foil so that the light-emitting diode protruding from the light-emitting diode foil does not come into direct contact with the inner surfaces of the two plastic layers.

Another object of the present invention relates to a method for producing a composite ^component according to the invention, in which first a first Plastic layer is provided. A first adhesive film, a light-emitting diode foil, a second adhesive foil and a second plastic layer are then successively arranged on this first plastic layer, wherein the first and / or the second plastic layer is transparent or translucent. Subsequently, the obtained layer assembly is optionally subjected to a vacuum to remove trapped gases, such as air. The resulting layer assembly is then compressed, with or without vacuum, at a suitable temperature and pressure, thereby obtaining a laminate. The vacuum, where appropriate, between the individual layers trapped gases, such as air, which can adversely affect the composite component, largely removed. Nevertheless, remaining residues of gases go under pressure in solution into the adhesive layer. After cooling the obtained laminate to a certain temperature, preferably to 30 ^° C. or lower, if a vacuum is applied, the vacuum is released to ambient pressure, whereby a composite component is obtained. This can then, if necessary, brought by a skilled person known processes in the desired size and / or deformed or deformed. Alternatively, the reshaping can be carried out prior to the lamination process described above, especially if the forming or shaping after the lamination is problematic.

The temperature during pressing depends on the adhesive film used. Suitable adhesive films are in particular polyvinyl butyral (PVB), ethyl vinyl acetate (EVA) and thermoplastic polyurethane (TPU) films. Preferably, the adhesive film used is transparent or translucent. If an EVA film is used, a temperature of 100 ^° C should not be exceeded. In a PVU foil, this upper limit is 120 ⁰ C and at a PVB film 135 ° C. When using a PVB film, the pressing is preferably carried out at a temperature in the range of 100 ⁰ C to 135 ° C, in particular 125 ° C to 130 ⁰ C.

The adhesive film used should be at least so thick that the light-emitting diodes projecting from the adhesive film are completely covered by the adhesive layer, since otherwise the light-emitting diodes easily break out of the film during manufacture. The thickness of the adhesive layer between the surface of the light-emitting diode foil fitted with the light-emitting diodes and the inner surface of one of the two plastic layers can be, for example, 0.5 to 3 mm, in particular 1.2 mm. In contrast to the first adhesive film, the other adhesive film can be selected to be thinner, since it only covers the underside of the light-emitting diode film, ie the side which is not connected to the light-emitting diodes. see, covered. In the case of the second adhesive film is therefore to pay attention to a sufficient adhesive effect, for which usually adhesive sheets having a thickness in the range of 0.1 to 1.0 mm, typically 0.4 mm, are sufficient.

As plastic layers, the plastic layers defined above can be used. The transparent or translucent plastic layer used preferably consists of one of the above-defined transparent or translucent thermoplastics, in particular of polyphenylsulfone. Preferably, both plastic layers consist of a transparent or translucent material. As light-emitting diode film, one of the light-emitting diode films defined above can be used.

The layers or films used in the process according to the invention are preferably electrostatically discharged before being arranged on one another, since an electrostatic charge can disturb the uniform formation of laminates. The electrostatic discharge can be done for example by grounding or ion showers.

Another object of the present invention relates to the use of a composite component according to the invention in the interior or exterior of buildings, i. the exterior or interior design, and in aircraft such as aircraft, watercraft, such as sailing or motor vessels, and land vehicles, such as rail vehicles or motor vehicles, especially passenger cars or trucks. The composite component according to the invention can be used, inter alia, as a lighting, information, reference, communication or signal element, in particular as a backlight element or starry sky, for illuminating edges, borders, for example handle borders, in partition walls or elements, as lettering, In particular, the composite component according to the invention can be used as an aircraft interior composite component in the interior of aircraft, in particular in aircraft for commercial aviation.
