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

Embodiments of light-emitting multilayer structures incorporating substrate films 3D-formed with recesses for light sources and plastics material molded thereupon are presented. Related methods of manufacture are set forth as well.

Illuminated structure and related method of manufacture

A method for manufacturing an electronic product, includes: obtaining a flexible, optically substantially transparent or translucent, substrate sheet; printing a number of electrical conductors on the substrate sheet in accordance with a predefined schematic; printing or disposing a number of electronic components including optoelectronic light emissive, preferably LED (light-emitting diode), components on the substrate sheet in accordance with the schematic, wherein at least some of the printed conductors are configured to provide electrical current thereto; and attaching a flexible, optically substantially transparent, lightguide sheet to the substrate so as to establish a functional multi-layer structure, where the light emitted by the light emissive components is incoupled to the lightguide, propagates therewithin, and is at least partly outcoupled to the environment through the substrate sheet. Related arrangement and electronic device are presented.
