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.

A structure includes a first substrate film and a functional electronics assembly. The first substrate film comprises a recess defining a volume. The functional electronics assembly comprises at least a first substrate, at least one electronics component on the first substrate, and at least one connection portion. The functional electronics assembly is connected to the first substrate film via the at least one connection portion. The at least one electronics component is arranged at least partly into the volume. At least part of the at least one electronics component is embedded into a first material arranged into the recess.

Method of manufacture of a structure and structure

A method of manufacture of a structure includes obtaining or producing a functional electronics assembly including at least a first substrate, at least one electronics component on the first substrate, and at least one connection portion, providing the functional electronics assembly on a first substrate film, wherein the functional electronics assembly is connected to the first substrate film via the at least one connection portion, and providing first material to at least partly embed the at least one electronics component into the first material. The first substrate film is adapted to include a recess defining a volume, and the at least one electronics component is arranged at least partly in the volume.
