Claim:
1. A light emitting device comprising: an ultraviolet light emitting diode to emit light in an ultraviolet wavelength region; blue phosphors, green phosphors, and red phosphors excitable by the ultraviolet light emitted by the ultraviolet light emitting diode to emit corresponding light that is combined with the ultraviolet light to form white light; and a converting part covering the ultraviolet light emitting diode comprising: a first molding part comprising the red phosphors covering the ultraviolet light emitting diode; a second molding part comprising the green phosphors covering the first molding part; and a third molding part comprising the blue phosphors covering the second molding part, wherein the white light includes ultraviolet light, green light, blue light, and red light, an intensity of a peak wavelength of the green light is in a range of 1.8 to 2.1 times the intensity of a peak wavelength of the blue light, an intensity of a peak wavelength of the red light is in a range of 2.8 to 3.1 times the intensity of the peak wavelength of the blue light, and the converting part has a hardness increasing from the first molding part to the third molding part.
