ABSTRACT:
A white light emitting device is disclosed. The white light emitting device includes a blue light emitting diode (LED) including a plurality of active layers generating different peak wavelengths, and phosphors emitting yellow light when excited by light emitted from the blue LED. The white light emitting device ensures enhanced excitation efficiency of the phosphors, and high luminance.
