ABSTRACT:
A light emitting device including three light emitting sources and a phosphor, with the three light sources consisted of following light emitting diodes (LED) emitting lights having different wavelengths. Wherein, two light sources are used to excite the phosphor to produce a distinct wavelength different from those of the two light sources. The distinct wavelength is blended with portions of the two light sources and a light source from another independent light source, and a blended light is released to obtain a white light.
