To protect a lighting fixture constituent member of a lighting fixture mounted on an exterior panel of an aircraft against damage caused by a thunderbolt without spoiling a lighting fixture function.SOLUTION: In a lighting fixture chamber 12, a retention cable 70 for electrically and mechanically connecting a metallic housing 20 and a metallic body support part 34 of a cover member 30 is arranged where light traveling from two light emitting elements 40 to a light transmission region 32A of a cover body 32 is not blocked. Further, the housing 20 is provided with a bolt 26 as a grounding terminal for electrically connecting the retention cable 70 to a body-side structure member of an aircraft. Consequently, even if a thunderbolt strikes on the exterior panel 2 nearby the housing 20, electricity is guided from the bolt 26 to the body-side structure member through the housing 20, and even if a thunderbolt strikes on the body support part 34 of the cover body 32, electricity is guided from the bolt 26 to the body-side structure member through the retention cable 70 and housing 20.SELECTED DRAWING: Figure 4

    【課題】航空機の外装パネルに装着される灯具において、灯具機能を損なうことなく雷の被害から灯具構成部材を保護可能とする。【解決手段】灯室12内に、金属製のハウジング20とカバー部材30の金属製の本体支持部34とを電気的かつ機械的に接続するための保持ケーブル70が、2つの発光素子40からカバー本体32の光透過領域32Aへ向かう光を遮光しない位置に配置された構成とする。また、ハウジング20に、保持ケーブル70を航空機の機体側構造部材に対して電気的に接続するための接地用端子としてボルト26が設けられた構成とする。これにより、ハウジング20付近において外装パネル2に落雷があってもハウジング20を介してボルト26から機体側構造部材へ電気を逃がし、また、カバー本体32の本体支持部34に対して落雷があっても保持ケーブル70およびハウジング20を介してボルト26から機体側構造部材へ電気を逃がすようにする。【選択図】図4
