An air duct system for an aircraft provides passengers with light, data, electrical power, and sanitized air. The air duct system includes an air duct having a main body and a visible light source configured to generate visible light, where the visible light is modulated by one or more controllers based on a visible light communication protocol. The air duct system simultaneously achieves four functions for improving passengers' flying experience. First, a portion of the visible light transmitted by the air duct illuminates the interior cabin of the aircraft. Second, by modulating the visible light, the air duct system transmits and distributes data that is received by the passengers' electronic devices. Third, a portion of the visible light is converted into electrical power at each passenger seat to power passengers' electronic devices. Fourth, in embodiments, the visible light is emitted at a germicidal wavelength spectrum to create sanitized air.

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.

A combined luminaire and air conditioning nozzle includes a front panel (101) with an opening. A nozzle frame (103) is pivotably connected to the opening of the front panel (101) so as to separate an air cavity (105) located behind the front panel (101) from a front side of the front panel (101). The structure includes a controller element (106) with a closing mechanism mechanically coupled thereto and arranged to adjustably limit an air passage (107) from the air cavity (105) to the front side of the front panel (101) in response to a movement of the controller element (106). A luminaire element (108) forms part of the closing mechanism and is provided with a light source arranged to output light to the front side of the front panel (101). The closing mechanism is arranged to convert a movement of the controller element (106) into a movement of the luminaire element (108), so that said adjustable limiting of the air passage (107) occurs as a result of said movement of the luminaire element (108).

An illuminated handle mounted to a surface of a crew work area includes an illuminated portion is disposed on an interior surface. A structural portion is integrated into work area stowage compartments, disposed between two stowage compartments, such that the illuminated portion illuminates the stowage compartments and their contents when opened. The illuminated handle includes an illuminated coat hook protrusion extending from a top portion of the illuminated handle. The illuminated portion of the illuminated coat hook is disposed on an interior surface to further illuminate the stowage compartments and indicate the location of the illuminated coat hook, while the hook extension prevents the illuminated portion from directly illuminating a crew member's face and potentially blinding the crew member momentarily.
