    摘要： A device for the generation of specific colored light including white light by luminescent down conversion and additive color mixing based on a light-emitting diode (LED) comprising a semiconductor light-emitting layer emitting near UV light about 370-420 nm or blue light about 420-480 nm and phosphors which absorb completely or partly the light emitted by the light-emitting component and emit light of wavelengths longer than that of the absorbed primary light, wherein the light emitting layer of the light emitting component is preferably a Ga(In)N-based semiconductor; and at least one of the phosphors contains a metal sulfide fluorescent material activated with europium containing at least one element selected from the group consisting of Ba, Sr, Ca, Mg and Zn; and/or at least another phosphor which contains a complex thiometalate fluorescent material activated with either europium, cerium or both europium and cerium containing 1) at least one element selected from the group consisting of Ba, Sr, Ca, Mg and Zn and 2) at least one element selected from the group consisting of Al, Ga, In, Y, La and Gd.
