Definitions

  • the present invention relates to a method for producing a three-dimensionally designed light-emitting component.
  • it relates to the production of such a component based on at least one electroluminescent film.
  • electroluminescent films consist of at least the following layers: a base film, a first electrode layer, a layer with luminescent pigments, a second, transparent electrode layer and a transparent cover film. Additional auxiliary layers such as barrier layers and / or dielectrics may be present. Furthermore, the cover and / or base films can simultaneously serve as electrode layers. All these layers are also referred to below as functional layers.
  • the electrode layers and the layer of luminescent pigments By applying a voltage - in inorganic electroluminescent structures of an AC voltage - an electric field is generated, which excites the luminescent pigment layer for light emission through the transparent electrode.
  • a structuring of the surface is often also necessary: For this purpose, a segmentation of the electrode layer must be made, while the luminescent pigment layer is both segmented and structurally unsegmented controlled. A segmentation of the pigment layer is usually carried out by printing different color pigment segments, while the electrode layers are effected by interrupting the electrical contacts within the layer and individual contacting of the segments thus obtained.
  • Such a shallow substrate construction due to the complexity of the layers and the segmentation, is a product which is only to some extent suitable for deformation into the third dimension.
  • use of electroluminescent films is also desirable in applications where decorative components have uneven surfaces. However, a bonding of electroluminescent films to such components is only possible if the component does not have too irregular irregularities or no strong surface curvatures, as otherwise air bubbles are easily trapped during application or because the adhesive electroluminescent composite sets up on the edge.
  • DE 19717740 A1 discloses a method in which an electroluminescent film is placed in an injection mold in the so-called in-mold process and back-injected with a hot, liquid plastic.
  • the film may have already been deformed in advance by deep drawing.
  • the complex film structure can be easily damaged by the hot liquid plastic.
  • locally high temperature peaks occur, which locally cause damage to the film structure and thus may render the entire component useless.
  • the deformation (for example deep drawing) of electroluminescent films is technically risky:
  • the functional layers can be mechanically destroyed in themselves, which may possibly jeopardize the functionality of the entire film structure.
  • the electrode layers, especially the first electrode layer (back electrode) described above are particularly susceptible to fractures, but damage to barrier layers, contacts or the pigment layer can cause the electroluminescent film in whole or in part no longer excited to glow can be.
  • the invention is therefore based on the object of providing a three-dimensional component with an electroluminescent structure in such a way that a light-emitting molded body is produced in a process-reliable manner and even in the case of very irregular surface structures which do not permit simple adhesion or lamination of a film.
  • FIG. 1 shows the layer structure of a film blank for a production process according to the invention
  • FIG. 2 shows an intermediate product in this process
  • FIG. 3 shows the end product of this process.
  • a film blank 101 which consists of the following three layers: On a lower film 102, a first electrode layer 103 is applied, on which (optionally with the provision of further intermediate layers such as barrier layers) a Leuchtpig- ment layer 104 is printed or applied.
  • Film blank 101 is a precursor for a complete electroluminescent layer construction.
  • any structure can be seen which has at least one electrode 103.
  • it may already have other electroluminescent functional layers. It is therefore called a film blank because a final second electrode layer is not present, so that the structure is not functional as a luminous film.
  • the film blank after a deformation and rear-injection process is represented as a three-dimensional component blank 206.
  • the layers 202-204 are to be understood analogously to FIG. 1, wherein the lower film 202 is injection-molded behind with an injection molding compound 209 and is thus connected to it.
  • the electroluminescent layer structure is now completed on the side of the film blank which faces the injection molding compound. This can be done by simple lamination by simple laminating, but preferably by printing or spraying, here indicated by a Spray nozzle 208.
  • a second (terminal) electrode layer and, if appropriate, further functional layers can be applied over the full or partial area.
  • Printing processes are particularly suitable if layers are to be applied only in some areas or particularly complicated surfaces are processed. According to the invention, screen printing, pad printing or digital printing are preferred as printing processes. Due to the possible strong unevenness, digital printing in particular is a suitable measure for adapting the printed image to the surface through flexible prediction. In particular, ink-jet printing methods are preferred for this purpose.
  • an at least partially transparent layer is applied as the electrode layer, since the electroluminescent light emission is to take place away from the injection-molded part (in the drawing above).
  • a transparent conductive ink is particularly preferred.
  • FIG. 3 shows the end product of the process; a three-dimensional component 312 with a permanently connected electroluminescent layer structure comprising at least the following functional layers: the lower foil 302 and the electrode 303 and the luminescent pigment layer 304 connected to the injection molding by fusing together, in addition to a second electrode layer 310 and a cover foil 311th
  • the procedure according to the invention described here has the advantage that particularly sensitive layers of an electroluminescent structure are not overstressed by deformation. Rather, they are added only after the final component shape is available. Therefore, this innovative basic idea is by no means limited to the film structures illustrated here or to back-injected films.
  • the basic principle is the presence of a body with an uneven surface on which electroluminescent functional layers are present and which is completed by suitable application processes in such a way that the remainder of the functional layers necessary for a functional electroluminescence structure are applied, in particular a final electrode.
  • a film structure can also take place from the other side, ie from a deep-drawn cover film with the first transparent electrode layer, onto which the functional layers are then applied in opposite order and then a back-injection takes place on the side opposite the cover film.
  • This Er- variant of the invention is particularly preferred in that the so-called (usually opaque) back electrode has proven to be the most sensitive functional layer.
  • Another embodiment of the invention is the completion of a rigid three-dimensional component, which likewise has at least one electroluminescent functional layer, to form an electroluminescent functional part.
  • a rigid three-dimensional component which likewise has at least one electroluminescent functional layer, to form an electroluminescent functional part.
  • injection-molded parts or thermoformed plastic plates can be considered as such rigid three-dimensional components.
