To equalize the quantity of light around a lighting object.SOLUTION: A transparent material 50, which is provided around a lighting object, comprises: a light entrance part 51 which light emitted from a light source enters; a light emission part 56 from which the light having entered the light entrance part 51 is emitted; and a light distribution part 53 that has at least a curved surface shape and that directly distributes the light, entered from the light source, in the direction of the light emission part 56. The light entrance part 51, which is thick enough to cover at least a light emission surface of the light source, is arranged on the light emission surface side of the light source.SELECTED DRAWING: Figure 3
【課題】照明対象物の周囲の光量を均一にすることである。【解決手段】導光体50は、照明対象物の周囲に設けられ、光源から出射された光が入射される入光部51と、入光部51に入射された光が出射される出光部56と、光源から入射された光を出光部56の方向に直接配光し、少なくとも曲面形状を有する配光部53と、を備える。入光部51は、光源の光の出射面側に配置され、当該光源の光の出射面を少なくとも覆う厚さを有する。【選択図】図3
