A lighting arrangement for a passenger cabin of an aircraft is provided. The lighting arraignment has a display surface for displaying image content, at least two luminaires in a lighting environment of the display surface and a control unit. The luminaires radiate light in accordance with at least one lighting parameter. In the control unit, each luminaire is assigned part of the display surface as an evaluation region and a mapping rule. The mapping rule assigns image content of the evaluation region values of the lighting parameters. The control unit, for each of the luminaires, assigns the image content of its evaluation region values of its lighting parameters using the mapping rule and actuates the luminaires with the values with regard to the assigned lighting parameters. A passenger cabin having the lighting arrangement and a method for actuating the luminaires are also provided.

A device including an outer shell having a first longitudinal axis and a first arcuate shape. The outer shell is opaque to ultraviolet light and to visible light. The device also includes an inner shell having a second longitudinal axis. The inner shell is connected longitudinally to the outer shell along a first longitudinal length and a second longitudinal length. The inner shell has a second arcuate shape different than the first arcuate shape. A chamber is disposed between the outer shell and the inner shell. The chamber is defined by a difference between the first arcuate shape and the second arcuate shape. The device also includes an ultraviolet light source disposed along the second longitudinal axis.

A system for monitoring traffic in aircraft cabins includes conductive wire in aisle carpeting and sensors to register pressure via capacitance changes. The system identifies the volume and location of traffic in aircraft aisles via registered changes to voltage, current, and/or conductivity of the conductive wire, and sensors embedded in the carpet. Measurements over time establish changes in traffic flow and directionality which may be used to direct crew members in flight. Lighting elements may be incorporated into the carpet to provide signals to passengers and crew via the lighting elements.

Interior panels for interiors of aircraft, aircraft, and methods from making interior panels for interiors of aircraft are provided. In one example, the interior panel includes an outer covering that has a first surface. The first surface is configured to be exposed to the interior of the aircraft. A second surface is disposed opposite the first surface. The second surface has a first pattern formed therein that is hidden from the first surface. A first light source is operative to generate a first light and is disposed adjacent to the second surface generally aligned with the first pattern. When the first light source generates the first light, a first illuminated pattern corresponding to the first pattern formed in the second surface is visible on the first surface.

A lighting device is provided that includes a light source and an optical element. The light source emits primary light having a primary emission characteristic. The optical element has a light entry face and a light exit face. The optical element includes light guiding elements each forming part of the light entry and exit faces. The light entry faces inject the primary light into the optical element. The light guiding elements each have a boundary surface that totally internally reflects the primary light so that the light exit face emits a secondary light. The optical element reduces a divergence of the primary light such that the secondary light has a secondary emission characteristic with an emission angle (β) that is smaller than an emission angle (α) of the primary emission characteristic. The light exit face is larger than the light entry face.

A method and apparatus for providing an occupant tracking lighting system including a first light, a second light and a third light within an aircraft cabin including detecting, by a sensor, a location and a velocity of a moving occupant, generating, by a processor, a control signal to illuminate the first light and the second light in response to determining that the location is proximate to the first location and that the velocity being towards the second location, and illuminating, by a controller, the first light and the second light in response to the control signal.

An aircraft passenger reading light comprises at least one reading light source, which is arranged for emitting visible light in a reading light emission direction; and at least one infrared light source, which is arranged for emitting infrared light in an infrared light emission direction. The infrared light emission direction is inclined with respect to the reading light emission direction.

Systems and methods for illuminating an airplane cabin using a light strip comprising a plurality of spectrally-tuned illuminators within a housing are provided. The illuminators include a first visible light illuminator and an infrared illuminator. The light strip is disposed to provide indirect infrared illumination of the cabin via diffuse reflection from a surface of the cabin (wash lighting) from a shrouded location. The illuminators include light emitting diodes (LEDs), and include white and some combination of red, yellow, green, and blue. A controller varies intensities of each illuminator, to emphasize or de-emphasize various colors or infrared illumination throughout an interior of the airplane cabin.

An aircraft emergency lighting system is disclosed. This emergency lighting system may include interior emergency lighting, interior ambient light sensors, exterior emergency lighting, and exterior ambient light sensors. The interior emergency lighting, the exterior emergency lighting, or both, may be controlled based upon an input of the interior ambient light condition (e.g., using an output from at least one of the interior ambient light sensors) and based upon an input from at least one of the exterior ambient light sensors.

A sanitization system for an aircraft cabin may comprise: a cabin of an aircraft; a light system including a lighting unit configured to emit an electromagnetic radiation output between 300 and 430 nanometers (“nm”); an external reactive oxygen species (ROS) generator in fluid communication with the cabin, wherein the sanitization system is configured to disinfect a target area of the cabin by targeting the target area with the electromagnetic radiation output and the ROS.
