An air duct system comprising an air duct having a main body, a visible light source, an emitter configured to emit radio frequency waves, and one or more antennas. The main body of the air duct defines a passageway having a reflective inner surface. The visible light source is configured to generate visible light. The visible light source directs the visible light along the reflective inner surface of the air duct. The emitter directs the radio frequency waves along the reflective inner surface of the air duct. The one or more antennas are each connected to a corresponding power harvesting circuit, where the radio frequency waves are received by the one or more antennas and are converted into electrical power by the corresponding power harvesting circuit.

An illumination device for a motor vehicle for displaying a linear light including a plurality of optical waveguides, an illuminating element having a plurality of light sources for coupling light into a respective first end face of the plurality of optical waveguides, and an emitting part for generating a linear light distribution, the optical waveguides being arranged with a respective second end face, which is different from the first end face, through the emitting part relative to one another along precisely one line.
