LUMINAIRE, ILLUMINATION SYSTEM AND MOBILE BODY

摘要

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
