Definitions

  • the present invention relates to a three-dimensionally designed light-emitting component and a method for producing the same.
  • it relates to such a component and method 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 or dielectrics may be present. Furthermore, the cover and / or base films can simultaneously serve as electrode layers.
  • a segmentation of the electrode layer must be made, while the luminescent pigment layer is segmented as well as unsegmented structured 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 flat film 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.
  • a use of electroluminescent films is also desired in applications where decorative components have uneven surfaces.
  • electroluminescent films on such components is only possible if the component does not have too uneven irregularities or strong surface curvatures, as otherwise easily air bubbles are trapped during application or the adhesive electroluminescent composite is positioned 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.
  • this poses the problem that 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 invention is therefore based on the object of providing a three-dimensional component with an electroluminescent film in such a way that a light-emitting molded body is formed reliably and even with more complex surface structures.
  • the object is achieved by heating and deforming a substrate and bonding to an electroluminescent film during this deformation process.
  • FIG. 1 shows the flow chart of a production process according to the invention of a component according to the invention
  • FIG. 2 shows an alternative flowchart of a production process according to the invention
  • FIGS. 3a and 3b show the end products (components) according to the invention of the above-described two production processes
  • FIG. 4 shows a flowchart of a production process according to the invention in continuous form
  • Figures 5a-c show various forms of forming tools for the continuous manufacturing process.
  • a substrate 101 is fixed by means of a tool 103.
  • a counter tool 104 with an electroluminescent film structure 102 fixed thereon is brought against the substrate 101.
  • the substrate 101 is plastically deformed and simultaneously connected to the electroluminescent film structure 102 at the contacting surfaces.
  • the electroluminescent film structure 102 of several
  • the purely superficial connection of substrate 101 and electroluminescent film structure 102 makes it possible to achieve a parallel deformation of both films and, on the other hand, to protect the electroluminescent structure in such a way that a functional product is produced.
  • the connection between the two elements usually takes place by superficial fusion.
  • Another possibility is the equipment with an activatable connection layer, such as an activatable adhesive.
  • activatable adhesives it is preferable to select those which are activated or heat-activated by heat or by cooling processes after the application.
  • hot-melt adhesives multi-component adhesives or latently reactive adhesives which react by heat supply and thereby harden.
  • adhesives which are excited by physical influences applied externally after the film deformation process for example, by electron beam or UV curing.
  • special pressure-sensitive adhesives can be used if they meet the respective requirements, especially for heat resistance and adhesion.
  • an electroluminescent structure 202 is inserted into a so-called deep-drawing mold. With the aid of a counter-mold 204 and under the influence of heat, a substrate 201 is brought into the mold, deformed and connected to the electroluminescent structure 202.
  • stamping rollers for example in the form of rotatable cylinders, balls, ellipses or cones, for example, with brush surface for better pressing
  • the end products 305a and 305b in FIGS. 3a and 3b differ, above all, in their shape, but may also vary in their functionality.
  • the electroluminescent structure 302a lies within a rounding. It may emit light either toward the substrate 301a, so that the device 305a would be a depression. Alternatively, this structure can also represent an increase if the electroluminescent structure 302a emits light through the substrate 301a.
  • the substrate must be designed at least partially transparent.
  • an electroluminescent foil 406 is guided from roll to a machine, as is a substrate 407, which is also delivered in endless form.
  • a substrate 407 which is also delivered in endless form.
  • both films are heated and brought together.
  • tools 409 and counter tools 410 shown here in the form of rollers, can be used for further shaping.
  • a merged and deformed endless composite 411 is led out of the machine and singulated at a separating unit (for example a punching or cutting machine) 413 so that finally components 412 are present.
  • a separating unit for example a punching or cutting machine
  • the advantage of such a continuous process is the faster feasibility and easier controllable process.
  • the disadvantage is that the shape usually always results in the same profile across the direction of web travel.
  • the indicated tools 409 and counter tools 410 can create a certain remedy here. They can be designed, for example, in the form of punches and counter-forms.
  • Figures 5a-c show various shapes of such rolls.
  • Figure 5a conventionally shaped, i. cylindrical rollers shown.
  • Figure 5b A variant of this are the tools shown in Figure 5b, of which the upper one barrel shape, the other has the counter-shape to it.
  • FIG. 5c A variant which is suitable for the production of surfaces with irregular profiles is shown in FIG. 5c.
  • rollers, or other rotating tools in the form of a punch (top) and a counter punch can be performed.
  • the endless composite instead of rotating rollers, the endless composite can also be pulled through a correspondingly shaped gap and thereby deformed.
  • a continuous process can also be understood as one in which one of the two elements-electroluminescent film 406 or substrate 407-is continuously supplied while the other element is dispensed as a single piece.
  • the manufacturing process disclosed herein has many sub-variants. They are used primarily depending on product, quantity and shape.
  • the obtained component can additionally be stabilized, for example by sub-spraying (preferably on the side of the substrate opposite the electroluminescent structure) or by bonding to a molded part.
  • the process according to the invention has then provided an intermediate workpiece which can be further refined. In any case, it can be ensured by the invention that the component has been manufactured with great care over the sensitive electroluminescent structure and yet effectively and cost-effectively.
