Beschreibung
Zusammenfassung:	Awarm-color complex phosphor includes: a Ce3+-activated orange phosphor that has an excitation peak within a blue wavelength range of 440 nm or more and less than 480 nm and has a fluorescence peak within an orange wavelength range of 580 nm or more and less than 610 nm; and a Ce3+-activated red phosphor that has an excitation peak within a green wavelength range of 500 nm or more and less than 550 nm and has a fluorescence peak within a red wavelength range of 610 nm or more and less than 660 nm. Preferably, the Ce3+-activated red phosphor is a nitride-based compound.
