摘要： An incandescent lamp color light emitting diode lamp comprises a semiconductor blue light emitting diode chip having a center emission wavelength in a range of from 400 nm to 480 nm and a phosphor that absorbs light emitted from the diode chip to emit light having a different wavelength than the light emitted from the diode chip. The phosphor is represented by a general formula of Mp(Si, Al)12(O, N)16:Eu2+q. The main phase is an α-SiAlON phosphor having an α SiAlON structure, wherein M is at least one element of Ca, Y, Mg, Li, Sc, Pr, Nd, Pm, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and Sr and p is from 0.75 to 1.0; and q is between 0.02 and 0.09. The diode lamp emits light having an emission color produced by a mixture of the light emitted from the semiconductor blue light emitting and the light emitted from the α-SiAlON. The chromaticity range thereof falls within the range defined by chromaticity coordinates (x, y) of (0.4775, 0.4283), (0.4594, 0.3971), (0.4348, 0.4185), and (0.4214, 0.3887) on the XYZ chromaticity diagram.

摘要： Conventional light emitting diode designs combined with blue light emitting diodes tend to lack in decorativeness and warmness. The present invention aims at providing a white light emitting diode for emitting white light with warmness at a higher luminance, and an intermediate color light emitting diode satisfying light emission in diversified color tones at a higher luminance. The solving means resides in adoption of a fluorescent material which is configured to emit yellowish red or red light and which comprises a CaAlSiN3 crystal phase including, dissolved therein in a solid state, one kind or two or more kinds of element(s) selected from Mn, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu, in a manner that the fluorescent material is mixed with another fluorescent material configured to emit green, yellowish green, or yellow light, and that the mixedly obtained phosphor is combined with a semiconductor light emitting element configured to emit bluish purple or blue light, to thereby fabricate a white light emitting diode for emitting white light with warmness at a high efficiency.
