| 20100295464 | ILLUMINATING DEVICE - An illuminating device comprising semiconductor light-emitting devices employing a semiconductor light-emitting element, wherein outputted light is stably combined, separation of light is inhibited, and color tone is variable. Control for operating the light-emitting devices is as simple as possible. It is an illuminating device comprising a light-emitting part comprising a plurality of kinds of semiconductor light-emitting devices which differ in emission color are integrated and arranged, the semiconductor light-emitting devices comprising a semiconductor light-emitting element and a phosphor, and wherein the semiconductor light-emitting devices emit light outward 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, wherein the semiconductor 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 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. | 11-25-2010 |
