PROBLEM TO BE SOLVED: To provide a luminaire for a vehicle cabin interior space which enables optical control with a three dimentional physical relationship between lighting and a radiation surface divided in vertical and lateral directions.SOLUTION: A luminaire 1 for a vehicle cabin interior space has: a light source 11; a lens part 30 having a first surface 31, which is exposed to a vehicle cabin inner side and has a predetermined light emitting area, and a second surface 32 located at a back side of the first surface 31; and a transparent material 20 which is disposed spaced a predetermined distance away from the lens part 30 and includes: an incident part 21 into which light from the light source 11 enters; and an emission part 22 from which the light entered from the incident part 21 emits toward the second surface 32 of the lens part 30. The lens part 30 is integrally molded with the transparent material 20. The transparent material 20 has a light control part 25 which reflects the light entered from the incident part 21 to the emission part 22 side. A shape that inhibits a high luminance part from appearing at a transparent material side and an incident part side of the lens part is formed in the optical control part.SELECTED DRAWING: Figure 8
【課題】照明と照射面の3次元的な位置関係を縦方向と横方向に分割して光学制御が可能な車両室内用照明装置を提供する。【解決手段】 車両室内用照明装置1は、光源11と、車両室内側に露出し所定の発光領域を有する第1面31と第1面31の裏面側の第2面32とを有するレンズ部30と、レンズ部30に対して所定の空間を隔てて配置され、光源11からの光を入射する入射部21と入射部21から入射された光をレンズ部30の第2面32に向けて出射する出射部22とを有する導光体20と、を有し、レンズ部30が、導光体20と一体成形されており、導光体20が、入射部21から入射された光を出射部22側へ反射させる光制御部25を有する。光制御部が、レンズ部の導光体側かつ入射部側に現れる高輝度部を抑制する形状が形成されている。【選択図】図8
