Claim 3:
4. The method of claim 2, further comprising at least one step selected from the group consisting of:
laminating two or more layers included in the multilayer structure together by pressure-sensitive adhesive, optically clear adhesive, solvent, ink, heat, pressure, or hot melt;
additively producing such as printing or 3D-printing at least one layer such as the plastic layer, a layer of the at least one reflective layer, a further material layer, a lightguide, a light outcoupling element, a diffuser, and/or other optically functional element; and
providing a top-emitting light source of the plurality of light sources on its side on the substrate film so that its contact pads face a direction transverse to the surface of the substrate film and are contacted by conductive adhesive provided on the substrate film electrically joining the contact pads with the circuit design, the conductive adhesive being at least partially surrounded on the substrate film by structural adhesive provided on the substrate film.
