Light emitting apparatus

摘要

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%, Nb₂O₅: 1 to 5%, La₂O₃: 0 to 5%, and TiO₂+Nb₂O₅+La₂O₃: 11 to 20% by mole percentage.
