Abstract:
A light emitting apparatus with high emission intensity and that is superior in weather resistance and reliability is obtained. The light emitting apparatus includes a light source and a wavelength-converting member for converting the wavelength of light emitted from the light source, wherein the wavelength-converting member contains a phosphor subjected to a cleaning treatment and/or a coating treatment, in a glass material having a composition of SiO2: 30 to 50%, Li2O: 0 to 15%, Na2O: 0 to 10%, K2O: 0 to 10%, Li2O +Na2O+K2O: 20 to 30%, B2O3: 5 to 15%, MgO: 0 to 10%, BaO: 0 to 10%, CaO: 0 to 10%, SrO: 0 to 10%, Al2O3: 0 to 10%, ZnO: 0 to 15%, TiO2: 10 to 20%, Nb205: 1 to 5%, La2O3: 0 to 5%, and TiO2+Nb2O5+La2O3: 11 to 20% by mole percentage.
