PROBLEM TO BE SOLVED: To provide a luminaire capable of adjusting the color temperature of illumination light, which is synthetic light, over a wide range and of preferably adjusting the brightness as the illumination light while maintaining the balance of each luminescent color.SOLUTION: A luminaire comprises: a substrate; a white-color light-emitting element group composed of a plurality of zonal white-color light-emitting elements which are formed separately from each other on the substrate; and a monochromatic light-emitting element group composed of a plurality of zonal monochromatic light-emitting elements which are at least one kind of the elements and formed separately from each other on the substrate. The whole light-emitting area of the white-color light-emitting element group is larger than the whole light-emitting area of the monochromatic light-emitting element group. |
