Claim Text:
1. A light for an aircraft, comprising a holder for carrying a first group of a plurality of first light emitting diodes arranged along a curvilinear line and comprising light emitting sites for emitting light in a direction away from the curvilinear line, a first optical unit of a reflective type comprising a first reflector extending around the holder for reflecting light emitted from the first light emitting diodes and defining an optical axis of the first optical unit, wherein the first reflector comprises an elliptic reflective partial surface defining (i) a plurality of first focal points forming a first curvilinear focal line extending along the light emitting sites of the first light emitting diodes, and (ii) a plurality of second focal points, wherein at least a portion of the elliptic reflective partial surface is arranged so as to face towards the first light emitting diodes, a second optical unit of a reflective and/or refractive type for emitting light received from the first optical unit into a predetermined area, wherein the second optical unit comprises a single further focal point or a plurality of further focal points forming a further curvilinear focal line, and wherein the plurality of the second focal points of the first optical unit or at least a second group of a plurality of second light emitting diodes arranged in at least one section of the first optical unit and displaced with respect to the first light emitting diodes in the direction of the extension of the optical axis of the first optical unit, wherein the plurality of second light emitting diodes are arranged outside of the plurality of first focal points and are arranged within the first reflector for emitting light towards the first reflector, wherein the second light emitting diodes emit light bypassing the second focal point or points of the first reflector of the first optical unit, with an area illuminated by the light due to the second light emitting diodes being wider than an area illuminated by the light due to the first light emitting diodes.
