Abstract
A white light emitting diode component capable of emitting white light includes an LED chip capable of emitting luminescent light, a first phosphor for absorbing first luminescent light of the luminescent light and emitting first emission, and a second phosphor for absorbing second luminescent light of the luminescent light and emitting second emission. A blend of the luminescent light (except for the first and the second luminescent light) and the first and the second emissions forms the white light. The first phosphor has a chemical formula of (CaEuM)Se, where x is not equal to zero, y is between zero and one, and M is composed of at least one element selected from a group consisting of Be, Mg, Sr, Ba, and Zn.
