The invention discloses a copying aircraft external curved plane-shaped refueling lamp and relates to the technical field of LED. The copying aircraft external curved plane-shaped refueling lamp comprises a main body piece, an LED assembly, a lens assembly, an aircraft skin assembly and a driving assembly. The invention further discloses a making method for the copying aircraft external curved plane-shaped refueling lamp. According to the copying aircraft external curved plane-shaped refueling lamp, certain optical index requirements are satisfied, the structure is simple, the operation is convenient, the process making is fast, and the reliability is high; It is important that the refueling lamp is mounted on the internal side of an aircraft skin, and the light emitting surface of the refueling lamp is an aircraft skin curved plane simulated design and adopts a streamline design; and therefore, wind resistance (zero wind resistance) is avoided; and a diffuser designed by using specific optics can realize optical deflection without spot size loss so that a standard requirement is satisfied.
