An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors preferably additively printed on the substrate film; a light source provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception; an optically transmissive plastic layer produced upon the first side of the substrate film, said plastic layer at least laterally surrounding, the light source, the substrate film at least having a similar or lower refractive index therewith; and a reflector design comprising at least one material layer, said reflector design being configured to reflect, the light emitted by the light source and incident upon the reflector design.

Optically functional multilayer structure and related method of manufacture

An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors on the substrate film; and a plurality of top-emitting, bottom-installed light sources provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception via associated outcoupling areas, wherein for each light source of the plurality of light sources there is optically transmissive plastic layer, produced upon the first side of the substrate film, said plastic layer at least laterally surrounding the light source, the substrate film at least having a similar or lower refractive index therewith; and reflector design including at least one material layer, provided at least upon the light source and configured to reflect the light emitted by the light source and incident upon the reflective layer towards the plastic layer.

Optically functionally multilayer structure suitable for large area illumination and related method of manufacture

An integrated optically functional multilayer structure includes a flexible, substrate film arranged with a circuit design including at least a number of electrical conductors on the substrate film; and a plurality of top-emitting, bottom-installed light sources provided upon a first side of the substrate film to internally illuminate at least portion of the structure for external perception via associated outcoupling areas, wherein for each light source of the plurality of light sources there is optically transmissive plastic layer, produced upon the first side of the substrate film, said plastic layer at least laterally surrounding the light source; the substrate film at least having a similar or lower refractive index therewith; and reflector design including at least one material layer, provided at least upon the light source and configured to reflect the light emitted by the light source and incident upon the reflective layer towards the plastic layer.

The multilayer structure including a substrate film and a number of functional components and/or integrated circuits, including at least one first conductive element, at least one second conductive element, and at least one subsidiary conductive element, optionally traces, provided upon the substrate film. The substrate film has been provided with at least one coupling location enhancement element at a coupling location with respect to the substrate film, wherein at said coupling location the coupling location enhancement element is configured to provide an electrical connection between the first conductive element and second conductive element, further wherein said coupling location enhancement element is configured to inhibit coupling between the first conductive element and the subsidiary conductive element at the coupling location and between the second conductive element and the subsidiary conductive element at the coupling location.
