An integrated functional multilayer structure, includes a flexible preferably 3D-formable and thermoplastic, substrate film; a lighting module provided upon the substrate film and preferably electrically connected to the circuit design thereon, the lighting module having a circuit board for hosting electronics; and circuitry arranged on the circuit board including at least one light source; a thermoplastic layer including one or more thermoplastic materials molded upon the substrate film and at least laterally surrounding, optionally also at least partially covering, the lighting module; wherein the circuitry on the circuit board of the lighting module including the at least one light source is configured to electrically and thermally connect to a number of locations of the remaining structure beside or underneath the circuit board utilizing at least one connection material positioned in between, preferably at least at the periphery of the circuit board. A related method of manufacture is also presented.

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

An integrated functional multilayer structure includes substrate film, circuitry provided upon the substrate film including a first light source and a monolithic lightguide layer, the lightguide layer includes a first surface and an opposite second surface, the second surface facing the first light source and a portion of the first surface containing, a pre-defined outcoupling area for the light emitted by the first light source and transmitted within the lightguide layer, the lightguide layer further containing a light leakage prohibition region and the attenuation of emitted light effectuated on a direct optical path between the first light source and the outcoupling area is less than the attenuation effectuating on a optical path between the first light source and the light leakage prohibition region. A related method of manufacture is also presented.
