PROBLEM TO BE SOLVED: To provide a luminaire capable of achieving multi-lighting only by wiring work of one luminaire.SOLUTION: A luminaire 1 (device body part 2) includes a plurality of light beam irradiation parts 5 for radiating a light beam B in a direction along a ceiling surface. In this luminaire 1, each of the plurality of light beam irradiation parts 5 radiates the light beam B in the direction along the ceiling surface. The light beam B is radiated on the surface wall of a habitable room in which the luminaire 1 is arranged, the radiated part itself generates scattering light and it becomes a secondary light source. As a result, the luminaire 1 achieves multi-lighting by radiating the plurality of light beams B. |
