ABSTRACT:
The present invention relates to a light emitting apparatus including a semiconductor light emitting element and a transparent ceramic phosphor for converting a wavelength of a light emitted from the semiconductor light emitting element, wherein the semiconductor light emitting element emits an ultraviolet light, and the ceramic phosphor corresponding to the semiconductor light emitting element has (i) a minimum transmission of 0.1 to 40% under a wavelength of 350-420 nm and (ii) a transmission of 10 to 90% under an emission peak wavelength of the ceramic phosphor.
