Abstract: Disclosed is a light emitting lamp bead, in which a blue light missing portion is effectively filled by means of a chip excitation phosphor combination having the waveband of 400 nm-415 nm, and phosphors also has strong absorption for purple light, so that a light emitting diode (LED) device having high light emitting efficiency may be obtained. For the waveband of 420 nm-460 nm, a blue phosphor also achieves emission; however, because the phosphors have broad peak emission, the intensity is weak with respect to a blue light excitation position, so that the harm of blue light is reduced.
