Abstract
An illuminating device comprising a plurality of semiconductor light-emitting devices differing in emission color and employing a semiconductor light-emitting element and a phosphor, wherein outputted light is stably combined, separation of light is inhibited, and color tone is variable, and which devices emit light outward on the basis of an emission from the semiconductor light-emitting element and from the phosphor which is excited by emission from the semiconductor light-emitting element to fluoresce or on the basis of emission from the phosphor which is so excited to fluoresce, 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 UCS (u,v) color system (CIE 1960), and outputted lights from the light-emitting part in which the plurality of kinds of the semiconductor light-emitting devices are integrated and arranged, are mixed together and emitted outward.
