1. A lighting device comprising:
at least one light guide comprising an elongated recess;
multiple light-emitting elements embedded into the elongated recess of the light guide, arranged on a flexfoil that is bendable in three different directions, and connected to one another to mimic a filament; and
at least one encapsulating material that encapsulates, at least in part, the at least one light guide, and comprises:
at least one opening, and
at least one reference element located at a position for aligning the at least one light guide in relation to the encapsulating material so that the multiple light-emitting elements emit light exiting the opening,
wherein the at least one encapsulating material is flexible so that the lighting device is bendable in the three different directions.
