Patent ID: 8541798

Claim:
A semiconductor white light emitting device comprising: an ultraviolet semiconductor light emitting element; a wiring connected to the ultraviolet semiconductor light emitting element; a wavelength converting material layer; and a light intensity difference reducing layer provided between the ultraviolet semiconductor light emitting element and the wavelength converting material layer, wherein the wavelength converting material layer contains a wavelength converting material comprising a mixture of three types of phosphors which, upon absorption of ultraviolet light emitted from the ultraviolet semiconductor light emitting element, emit red light, blue light, and green light, respectively, the light intensity difference reducing layer is formed of a silicone resin, the ultraviolet semiconductor light emitting element and the wiring are completely covered by the light intensity difference reducing layer, and the blue light emitting phosphor is represented by formula (I): (Sr 1-x-y Ba x Ca y Eu z ) 10 (PO 4 ) 6 .Cl 2 (I) wherein x, y, and z are x<0.2, y<0.1, and 0.005<z<0.1, respectively.
