PROBLEM TO BE SOLVED: To provide a luminaire capable of reducing unevenness in illumination light.SOLUTION: A long luminaire 10 includes: a light source (linear light source 20); and a long optical member 30 for emitting light entered from the light source. The optical member 30 includes: a long light incident surface 30b in which light from the light source enters; and a long light emission surface 30a from which the light entered from the light incident surface 30b emits. In the optical member 30, a plurality of light diffusion parts 31 are provided on the light emission surface 30a, and out of the plurality of light diffusion parts 31, the direction of light distribution of the light diffusion parts 31a provided in the vicinity of one end in the longitudinal direction of the optical member 30 is inclined to the direction heading to the one end from the light diffusion part 31a in the longitudinal direction from the direction of the light distribution of the luminaire 10.SELECTED DRAWING: Figure 5D
【課題】照明光のむらを低減することができる照明装置を提供する。【解決手段】長尺状の照明装置10であって、光源(線状光源20)と、当該光源から入射された光を出射する長尺状の光学部材30とを備え、光学部材30は、当該光源からの光が入射する長尺状の光入射面30bと、光入射面30bから入射した光が出射する長尺状の光出射面30aとを備え、光学部材30には、光出射面30aに、複数の光拡散部31が設けられ、複数の光拡散部31のうち、光学部材30の長手方向の一端の近傍に設けられた光拡散部31aの配光の向きは、照明装置10の配光の向きから、長手方向における当該光拡散部31aから当該一端へ向かう向きに傾斜している。【選択図】図5D
