MULTILAYER STRUCTURE WITH EMBEDDED LIGHT SOURCE AND LIGHT-GUIDING FEATURES AND RELATED METHOD OF MANUFACTURE

An integrated multilayer structure (100, 200, 300, 400, 600, 700), comprises a substrate film (102) having a first side and an opposing second side; electronics comprising at least one light source (110), optionally a LED, provided upon the first side of the substrate film and a number of electrical conductors (112), preferably printed by printed electronics technology, at least electrically coupled to the at least one light source (110), the at least one light source (110) being configured to emit light in selected one or more frequencies or wavelengths, optionally including visible light; an optically transmissive element (104) comprising thermoplastic optically transmissive, having regard to the selected frequencies or wavelengths, material having a first refractive index and produced, preferably through utilization of molding from said optically transmissive thermoplastic material, onto the first side of the substrate film (102) so as to at least partially embed the at least one light source (110) therewi
