Abstract:
1. An illuminating device comprising: a first to an Nth solid-state light-emitting device, wherein: N is an integer equal to or greater than two; first to Nth solid-state light-emitting devices differ in emission color, and each comprises a semiconductor light-emitting element having an emission peak wavelength in a range of 350 nm to 430 nm and having an emission region belonging to near-ultraviolet region or ultraviolet region; and a phosphor and emits a primary light on the basis of an emission from the semiconductor light-emitting element and an emission from the phosphor which is excited by said emission from the semiconductor light-emitting element to fluoresce, or on the basis of an emission from the phosphor which is excited by an emission from the semiconductor light-emitting element to fluoresce; the first to Nth solid-state light-emitting devices each have an emission color, the deviation duv of which from a blackbody radiation locus being within a range of −0.02≦duv≦0.02, in the uv chromaticity diagram according to USC (u,v) color system (CIE 1960); and a synthesized light which is synthesized from primary lights emitted by the first to Nth solid-state light-emitting devices is emitted outward.
