Patent ID: 8829781

Claim:
A light-emitting device comprising a light-emitting element that is a gallium nitride-based semiconductor emitting primary light having a peak wavelength of 430 to 480 nm, and a light converter including a first phosphor absorbing a part of the primary light emitted from the light-emitting element and emitting secondary light having a longer wavelength than the primary light, and a second phosphor emitting secondary light having a longer wavelength than the secondary light emitted from the first phosphor, wherein said the second phosphor is a tetravalent manganese-activated fluoro-tetravalent metalate phosphor substantially represented by a general formula (C): MII 2 (MIII 1-h Mn h )F 6 (in said general formula (C), MII represents at least one alkaline metal element selected from Li, Na, K, Rb and Cs, MIII represents at least one tetravalent metal element selected from Ge, Si, Sn, Ti and Zr, and 0.001≦h≦0.1), and wherein a mixing ratio of the second phosphor is higher than that of the first phosphor.
