Zusammenfassung:PROBLEM TO BE SOLVED: To provide a lighting fixture which can improve light extraction efficiency, while securing a uniformity ratio of a shade.SOLUTION: A lighting fixture 10 includes a fixture body 11, a light emitting module 12, a light source cover 13 and a shade. The light emitting module 12 includes a substrate 22 disposed in the fixture body 11, and a plurality of light emitting elements 23 mounted on the substrate 22. At the light emitting module 12, the plurality of light emitting elements 23 are arrayed along circumferences of different diameters respectively, and a plurality of rows of light emitting element rows 24 are provided. In the light source cover 13, annular lens parts 28 opposing to the light emitting element rows 24 and for controlling light distribution, and annular light transmission parts 29 opposing to the light emitting element rows 24 different from the light emitting element rows 24 which the lens parts 28 are opposing to and having higher light transmission efficiency than that of the lens parts 28 are formed integrally. The shade 14 covers the light emitting module 12 and the light source cover 13 and is mounted on the fixture body 11.SELECTED DRAWING: Figure 1 【課題】セードの均斉度を確保しつつ、光取出効率を向上できる照明器具を提供する。【解決手段】照明器具10は、器具本体11、発光モジュール12、光源カバー13およびセードを備えている。発光モジュール12は、器具本体11に配設される基板22、および基板22に実装される複数の発光素子23を有する。発光モジュール12には、異なる径の各円周上に沿って複数の発光素子23が配列されて複数列の発光素子列24が設けられている。光源カバー13は、発光素子列24に対向し、配光を制御する環状のレンズ部28と、レンズ部28が対向する発光素子列24とは異なる発光素子列24に対向し、レンズ部28よりも光透過効率が高い環状の光透過部29とが一体に形成されている。セード14は、発光モジュール12および光源カバー13を覆い、器具本体11に取り付けられる。【選択図】図1
