Claim Text:
1. A light emitting apparatus, comprising: a light emitting element which is a gallium nitride-based semiconductor emitting primary light having a peak wavelength of 430 to 480 nm; and a light converter absorbing a part of said primary light to emit secondary light having a wavelength longer than a wavelength of the primary light, wherein the light emitting apparatus emits white light by color mixture of primary light and secondary light, said light converter including a green light emitting phosphor and a red light emitting phosphor, said green light emitting phosphor is a divalent europium-activated oxynitride green light emitting phosphor which is a β-type SiAlON substantially represented by a general formula (A): Eu said divalent europium-activated oxynitride green light emitting phosphor satisfies 9 μm≦d1≦16 μm, and 12.5 μm≦50% D≦35 μm.
