PROBLEM TO BE SOLVED: To perform downward light radiation and clear-light line radiation to a ceiling face by using a single light source.SOLUTION: A lighting fixture 1 comprises: a light source 3 suspended from a ceiling face; a shade 2 covering the circumference of the light source 3; and a reflection mirror 4 arranged at a lower position rather than the light source 3 being a radial outside position within the shade 2. A light permeation part 5 extending to the circumferential direction is formed at a middle part of the axial direction of the shade 2. The light source 3 is arranged in an upper position rather than a window part 5, and the reflection mirror is arranged in a lower position rather than the window part. By this constitution, a part of light radiated from the light source 3 is reflected by the reflection mirror 4, the reflection light is projected to the ceiling face through the window part 5, and a remaining part of the light from light source 3 is projected downwardly from a lower end opening part of the shade 2. 【課題】単一の光源を用いて、下方への光の照射と、天井面への明確な光のラインの照射とを行う。【解決手段】本発明の照明器具１は、天井面から吊り下げられた光源３と、光源３の周囲を覆うシェード２と、シェード２内で光源３よりも下方位置且つ径方向外方位置に設けられた反射鏡４とを備える。シェード２の軸方向中途部には周方向に延びる光透過窓部５を形成する。光源３は窓部５よりも上方位置に設けられ、反射鏡は窓部よりも下方位置に設けられる。これにより、光源３から放射される光の一部が反射鏡４により反射され、この反射光を窓部５を通って天井面に投射させるとともに、シェード２の下端開口部から下方に向けて光源３からの光の残部を投射させる。【選択図】図１
