The present invention provides a light emitting device, comprising at least one of light emitting diodes for emitting lights with wavelengths of blue and ultraviolet regions; an or- thosilicate based phosphor excited by the light emitted from the light emitting diode to emit light in a green region; and an orthosilicate based phosphor excited by the light emitted from the light emitting diode to emit light in a red region. The light emitting device of the present invention can implement white light with a continuous spectrum ranging from green to red to obtain excellent color rendering, and thus there is an advantage in that the light emitting device may be employed as a lighting source for flashes, general illuminators, household electronics or business machines.
