摘要： A dual sided aircraft light assembly includes a mount structure, a plurality of first light emitters, a plurality of first optics, a plurality of second light emitters, and a plurality of second optics. The first light emitters are disposed such that, upon being energized, each emits light in a first direction that is at an acute angle relative to a reference line that extends in a reference direction. The first optics are configured to focus the light emitted from the first light emitters into a first light beam directed in the first direction. The second light emitters are disposed such that, upon being energized, each emits light in a second direction that is at an obtuse angle relative to the reference line and reference direction. The second optics focus the light emitted from the second light emitters into a second light beam directed in the second direction.

摘要： A lighting system for an aircraft having at least one rotationally mounted propeller assembly that includes hub and a plurality of rotor blades extending radially away from the hub includes a light source and an optical element. The light source is mounted within the hub and is configured, upon being energized, to emit light in a first direction. The optical element is mounted within the hub and is disposed to receive the light emitted by the light source and is configured, upon receipt of the light, to redirect the light radially outward from the hub so that the light reflects off the rotor blades.
