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.

White light emitting diode component having two phosphors and related phosphor and formation method

A light-emitting diode (LED) component includes a light-emitting chip for emitting luminescent light, and a phosphor for absorbing first luminescent light of the luminescent light and emitting first emission, the first luminescent light having a first wavelength different from that of the first emission, the phosphor having 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.

Light emitting diode component capable of emitting white lights

A method for manufacturing white light source includes the steps of providing an ultra-violet light as radiation source; and preparing two kinds of phosphors each receiving the ultra-violet light and emitting light of different wavelength. One phosphor is designated to emit light covering two wavelength regimes of three primitive colors, i.e., red light (585-640 nm), green light (500-570 nm) and blue light (430-490 nm), and another phosphor is designated to emit light covering remaining wavelength regime of the three primitive colors. The phosphors are mixed in predetermined ratio such that the lights of different wavelength are combined to provide a white light.
