Aircraft lighting unit with lens that splits light of single light-emitting element in different directions

An aircraft light comprising:

• at least one or more light-emitting elements as light sources;
• and
• an inner lens configured to project light emitted from the light-emitting elements onto a desired area,
• the inner lens includes a lens that splits light of a single light-emitting element in different directions,
• the lens is a multi-curved surface lens including a plurality of lens surfaces whose regions partially overlap one another,
• the multi-curved surface lens is a freeform lens formed by coupling three curved surfaces each having an output surface with a different curvature,
• the multi-curved surface lens is divided into a first region, a second region, and a third region,
• the single light-emitting element is placed in the central portion of the multi-curved surface lens in plan view in such a manner as to be at least partially related to all of the first region, the second region, and the third region,
• the directions of light emission of the first region, the second region, and the third region are different from one another, wherein
• when a beam emitted from the single light-emitting element passes through the multi-curved surface lens, the beam is split into three different directions.
