PROBLEM TO BE SOLVED: To provide a lighting fixture which improves efficiency of mounting work to a mounted panel.SOLUTION: An LED lighting fixture includes: a case part 21 having a plurality of fan-shaped blade parts 23, 24 on a peripheral wall of a cylindrical part 22 which can radiate illumination light toward the outside; and a frame 2 having a plurality of divided cylindrical wall parts 12, 13 which can cover a plate part 11 and the peripheral wall part of the cylindrical part 22. The cylindrical part 22 is inserted in a through-hole 102 from one side of a ceiling plate 101, and the divided cylindrical wall parts 12, 13 are inserted from the other side of a ceiling plate 101 so as to cover the cylindrical part 22. Arrangement is made in such a manner that on one side of the ceiling plate 101, the plurality of blade parts 23, 24 are located and on the other side of the ceiling plate 101, the plate part 11 is located. When the frame 2 is rotated, the blade parts 23, 24 enter a notch part of the divided cylindrical wall parts 12, 13, and the case part 21 and the frame 2 are crossed and engaged. Thereby, the LED lighting fixture is mounted on the 101, by sandwiching the ceiling plate 101 between the blade parts 23, 24 and the frame 2.SELECTED DRAWING: Figure 7
【課題】被取付パネルへの取付作業の効率を向上する灯具を提供する。【解決手段】LED灯具は、照明光を外部に向けて照射可能な円筒部22の周壁に扇形状の複数の羽根部23、24を有するケース部21と、プレート部11および円筒部22の周壁を被覆可能な複数の分割筒壁部12,13とを有するフレーム2を備える。円筒部22を天井板101の一方側から貫通穴102に挿入し、分割筒壁部12、13を天井板101の他方側から円筒部22を被覆するように挿入する。複数の羽根部23、24が天井板101の一方側に、プレート部11が天井板101の他方側に位置するように配置し、フレーム2を回転させると、羽根部23、24が分割筒壁部12、13の切欠部に進入し、ケース部21およびフレーム2が交差して係合する。これにより、羽根部23、24およびフレーム2で天井板101を挟み込んでLED灯具が天井板101に取り付けられる。【選択図】図7
