To provide an aircraft lighting unit capable of irradiating a region-to-be-irradiated with an appropriate illumination intensity.SOLUTION: An aircraft lighting unit is configured to comprise at least one light emitting element as a light source and an inner lens that irradiates toward a desired region with light emitted from the light emitting element, in which the inner lens includes a lens that splits light from the single light emitting element into different directions. With this aspect, it becomes possible to irradiate both a distant irradiation region and a nearby irradiation region, and to adjust luminous intensity by adjusting the amount of split light beams to thereby irradiate a region-to-be-irradiated with an appropriate illumination intensity.SELECTED DRAWING: Figure 3

    【課題】被照射領域を適切な照度で照射可能な航空機用灯具を提供する。【解決手段】光源としての、少なくとも1以上の発光素子と、前記発光素子から出射された光を所望の領域に向けて照射するインナーレンズとを備え、前記インナーレンズは、単一の前記発光素子の光を異なる方向へ分割するレンズを含むように、航空機用灯具を構成した。この態様により、遠方の照射領域と近方の照射領域の両方を照射可能となり、かつ分割する光束の量を調整することにより、光度も調整できるため、被照射領域を適切な照度で照射可能となる。【選択図】図3
