Claim 24:
25. A method for manufacturing an integrated optically functional multilayer structure, comprising:
obtaining a flexible, substrate film, provided with a circuit design comprising at least a number of electrical conductors additively produced, on the substrate film;
arranging a plurality of top-emitting, bottom-installed light sources provided upon a first side of the substrate film;
providing laminating or 3D printing, for each light source of the plurality of light sources, an optically transmissive plastic layer upon the first side of the substrate film, said plastic layer at least laterally surrounding or neighbouring, the light source;
a reflector design comprising at least one material layer is provided and configured to reflect, the light emitted by the plurality of light sources and incident upon the reflector design; wherein
the optically transmissive plastic layer is at least partially provided as a pre-manufactured element initially separate from the first side of the substrate film.
