Abstract
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.
