An aircraft light unit (2), has a support portion (4), a light source having at least one LED (6), the light source being arranged on the support portion (4) and in operation emitting light with a source-side light intensity distribution, and an optical element (8) for transforming the source-side light intensity distribution into an output light intensity distribution. The optical element (8) has at least two transformation segments (10, 20, 30), covering different angular ranges of the source-side light intensity distribution in a first crosssectional plane. The at least two transformation segments (10, 20, 30) include a first transformation segment (10), with the light from the light source experiencing total internal reflection within the optical element (8) in the first transformation segment (10) and being bundled in a peak region of the output light intensity distribution, and at least one further transformation segment (20, 30), with the light from the light source experiencing refraction only in the at least one further transformation segment (20, 30).
