PROBLEM TO BE SOLVED: To provide a luminaire for a vehicle cabin interior space which enables optical control with a three dimensional 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 curve part 23 which is formed between the incident part 21 and the emission part 22, has a diffusion function, and is formed into a curved shape; a body part 24 which is formed from the curve part 23 in a linear shape along at least the lens part 30; and a light control part 25 which is formed in the body part 24 and reflects the light entered from the incident part 21 to the emission part 22 side.SELECTED DRAWING: Figure 4 |
