Patent ID: 8740424

Claim:
A light for an aircraft, comprising a holder (18,118,218,318) for carrying a plurality of light emitting diodes (20,120,220,320) 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 (14,114,214,314) of a reflective type comprising a first reflector (22,122,222,322) extending around the holder (18,118,218,318) for reflecting light emitted from the light emitting diodes (20,120,220,320), wherein the first reflector (22,122,222,322) comprises an elliptic reflective partial surface defining (i) a plurality of first focal points (30,130,230,330) forming a first curvilinear focal line extending along the light emitting sites of the light emitting diodes (20,120,220,320), and (ii) a plurality of second focal points (32,132,232,332), wherein at least a portion of the elliptic reflective partial surface (24,124,224,324) is arranged so as to face towards the light emitting diodes (20,120,220,320), a second optical unit (16,116,216,316) of at least one of a reflective or refractive type for emitting light received from the first optical unit (14,114,214,314) into a predetermined area, wherein the second optical unit (16,116,216,316) 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 (32,132,232,332) of the first optical unit (14,114,214,314) either coincide and are identical to the single further focal point of the second optical unit (16,116,216,316) or are located along the further curvilinear focal line of the second optical unit (16,116,216,316); wherein the first reflector (22,122,222,322) further comprises a spheric reflective partial surface (34,134,234,334) adjacent the elliptic reflective partial surface and extending from a portion thereof facing the light emitting diodes (20,120,220,320).
