LED lighting device of an aircraft, in particular for maneuvers of landing, take-off, taxiing, and searching, and aircraft comprising said device

摘要

AN LED lighting device of an aircraft for maneuvers of landing, and/or take-off, and/or taxiing, and/or searching comprising: one or more light-emitting modules including a light-emitting semiconductor device configured for emitting a light radiation; a supporting substrate carrying the light-emitting semiconductor device; a curved reflector having a concave reflecting surface and defining a plane of emission, wherein the concave reflecting surface has a semiparabolic shape obtained by sectioning a semiparaboloid along two mutually parallel cutting planes, and is arranged facing the light-emitting semiconductor device in such a way as to collect the light radiation and generate a radiation reflected through the plane of emission.
