    摘要: 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.

    摘要: PROBLEM TO BE SOLVED: To provide a light-emitting apparatus which is excellent in heat radiation performance and hardly causes deformation or damage due to an external force in manufacturing processes or when it is mounted on a circuit board. SOLUTION: The apparatus has a package provided with a recess having an internal wall and a bottom surface on its upper surface, and a lead terminal exposed on the bottom surface of the recess and protruding from the side surface of the package. The lead terminal has a first lead terminal receiving a semiconductor light-emitting device to be arranged, and having a thick film region exposed also from the rear surface of the package; and a second lead terminal to be conducted to the semiconductor light-emitting device. In the first lead terminal, the rear surface of the thick film region is on the same plane as that of the rear surface of a protruding region protruding from the side surface of the package. The rear surface of the package has a first rear surface on the same plane as those of the rear surface of the thick film region and the rear surface of the protruding region, and a second rear surface contacting the thick film region and recessed from the first rear surface.
