Abstract

An exterior aircraft light unit for emitting light of a first wavelength and light of a second wavelength, different from the first wavelength is disclosed. The exterior aircraft light unit has an integrated optical structure, which in turn has a first light source configured to emit the light of the first wavelength, a second light source configured to emit the light of the second wavelength, the second light source being positioned adjacent to the first light source, and an optical element for shaping a light emission distribution of the integrated optical structure. The optical element is arranged with respect to the first light source and the second light source in such a way that it affects both the light of the first wavelength and the light of the second wavelength.
