Abstract: A colored light for the passengers of a passenger transportation means, in particular for the cabin of an aircraft, comprises a plurality of illuminating means, each emitting electromagnetic waves in a narrow-band wavelength range, wherein the wavelength ranges preferably do not overlap each other. Further, the colored light is provided with a drive unit for driving the illuminating means such that a soothing or stimulating effect on the passengers can be achieved via the color sensation of the human eye and the thus triggered (bio-) chemical processes in the body.

Abstract: An aircraft position light for an aircraft is provided with a luminous device for emitting light and a reflector arrangement. The luminous device comprises a first and a second light source, which emit light within a light radiation solid angle, the two light sources being arranged symmetrically to the preferential axis and central axes of the light radiation solid angles being inclined so as to face each other. The reflector arrangement comprises a first and a second reflection surface allocated to the first and second light source, respectively. The first reflection surface is arranged opposite to the first light source and the second reflection surface is arranged opposite to the second light source.
