To control the light distribution of an exit light.SOLUTION: A light refractive member 8 includes: an entrance surface 6 which a planer light 9 enters; a plurality of refractive units 81 for bending the planer light 9; and an exit surface 7 for bending the planar light 9 by a plurality of refractive units 81 and emitting the planar light as an exit light 14. The plurality of refractive units 81 are provided in one direction in one of the entrance surface 6 and the exit surface 7, and have a region where the direction of bending the planer light 9 changes according to a direction intersecting with the one direction.SELECTED DRAWING: Figure 1
【課題】出射光の配光を制御すること。【解決手段】光屈折部材8は、面状光9が入射する入射面6と、面状光9を屈折させる複数の屈折部81と、面状光9が、複数の屈折部81により屈折され、出射光14として出射される出射面7と、を備える。複数の屈折部81は、入射面6と出射面7との少なくともいずれか一方に、一方向において並んで設けられており、前記一方向に交差する方向に沿って、面状光9を屈折させる方向が変化する領域を有する。【選択図】図1
