Embodiment Construction

[0106] figure 1 A first exemplary embodiment of the multilayer body 1 is shown. The multilayer body comprises a carrier layer 2 . An optical auxiliary layer 3 is applied on one side of the carrier layer 2 , on which a decorative layer 4 is again arranged. A recess 41 is provided in the decorative layer 4 , which also penetrates the auxiliary layer 3 . As an alternative and not shown here, an optically clear varnish or another material can also be provided in the recess 41 .

[0107] On the side of the carrier layer 2 facing away from the auxiliary layer 3 and the decorative layer 4 , a conductor track layer 5 is applied, by means of which the luminous means 6 are contacted.

[0108] On the side of the luminous means 6 , a plastic layer 7 is injection molded, on which the further optical auxiliary layer 3 ′ adjoins.

[0109] The carrier layer 2 can be configured as a film. Preferably the film is made of PET, PEN, PC, PVC, It is made of PLA, PMMA or ABS and has a layer th...

Abstract

The invention relates to a method for producing a multilayer body, having the following steps: a) providing a support layer on which at least one lighting means, in particular an LED, is arranged; b) providing a decorative layer; and c) injecting a plastic layer onto the support layer and / or the decorative layer in an injection mold. The invention further relates to a multilayer body produced using such a method.

Description

technical field [0001] The invention relates to a method for producing a multilayer body and the multilayer body produced in this way. Background technique [0002] The requirement to integrate electronic functions in addition to decoration in the manufacture of plastic components is also increasing. Plastic parts have long been equipped with light-emitting elements for indicating to the user the status of certain devices (eg switching elements in motor vehicles, control panels of domestic appliances). [0003] For this purpose, it is usually necessary in an additional step to connect the decorated plastic part to a conventional circuit board with light-emitting elements, such as light-emitting diodes, and / or other electronic components. It is often necessary to add additional layers between the plastic panel and the luminous element in a further manufacturing step, which convert, for example, a point light source, such as a light-emitting diode, into an area light (diffuse...
