The light for an aircraft comprises a holder (18,118,318,418) for carrying a plurality of light emitting diodes (20,120,320,420) arranged along a curvilinear line and comprising light emitting sites for emitting light in a direction away from the curvilinear line and a first optical unit (14,114,314,414) of a reflective type comprising a first reflector (22,122,322,422) extending around the holder (18,118,318,418) for reflecting light emitted from the light emitting diodes (20,120,320,420). The first reflector (22,122,322,422) comprises an elliptic reflective partial surface defining (i) a plurality of first focal points (30,130,330,430) forming a first curvilinear focal line extending along the light emitting sites of the light emitting diodes (20,120,320,420), and (ii) a plurality of second focal points (32,132,332,432), wherein at least a portion of the elliptic reflective partial surface (24,124,324,424) is arranged so as to face towards the light emitting diodes (20,120,320,420). The light for an aircraft further includes a second optical unit (16,116,316,416) of a reflective and/or refractive type for emitting light received from the first optical unit (14,114,314,414) into a predetermined area. The second optical unit (16,116,316,416) comprises a single further focal point or a plurality of further focal points forming a further curvilinear focal line. The plurality of the second focal points (32,132,332,432) of the first optical unit (14,114,314,414) either coincide and are identical to the single further focal point of the second optical unit (16,116,316,416) or are located along the further curvilinear focal line of the second optical unit (16,116,316,416). The light comprises at least a second group of a plurality of second light emitting diodes (464) arranged in at least one section (466) and displaced with respect to the first light emitting diodes (20,120,320,420) in the direction of the extension of the optical axis (31,131,331,431) of the first optical unit (14,114,314,414), wherein the second light emitting diodes (464) emit light bypassing the second focal point or points (32,132,332,432) of the first reflector (22,122,322,422) of the first optical unit (14,114,314,414). |
