Patent ID: 8362685

Claim:
A light-emitting device comprising a light-emitting element emitting primary light, and a light converter 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, said light converter including a green light-emitting phosphor and a red light-emitting phosphor, said red light-emitting phosphor including at least one selected from: 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 a tetravalent manganese-activated fluoro-tetravalent metalate phosphor substantially represented by a general formula (D): MIV(MIII 1-h Mn h )F 6 (in said general formula (D), MIV represents at least one alkaline earth metal element selected from Mg, Ca, Sr, Ba and Zn, MIII represents at least one tetravalent metal element selected from Ge, Si, Sn, Ti and Zr, and 0.001≦h≦0.1), and wherein the green light-emitting phosphor is mixed within the range of 5 to 70% of the green light-emitting phosphor and red light-emitting phosphor by weight ratio.
