Integrated multilayer structure containing optically functional module and related method of manufacture

An integrated functional multilayer structure comprising:

• a flexible substrate film comprising at least a number of electrical conductors;
• a lighting module provided upon the flexible substrate film, said lighting module comprising:
• a circuit board for hosting electronics;
• and
• circuitry arranged on the circuit board, the circuitry comprising at least one light source and/or at least one other electronic component;
• a 3D-shaped sheet comprising thermally conductive sheet material at least thermally connecting to the circuit board, wherein the 3D-shaped sheet extends by its 3D-shape through the substrate film via a hole in the flexible substrate film;
• a thermoplastic layer comprising one or more thermoplastic materials molded upon the flexible substrate film and at least laterally surrounding the lighting module;
• wherein the circuitry on the circuit board of the lighting module is configured to electrically and thermally connect to a number of locations of the remaining multilayer structure beside or underneath the circuit board utilizing at least one connection material.
