ABSTRACT:
A semiconductor light emitting device ensuring a uniform color tone comprises a semiconductor light emitting element that emits light of a first wavelength upon injection of a current, a fluorescent material portion that contains a fluorescent material excited by light of the first wavelength to emit light of a second wavelength, and a diffuser mixed in an appropriate material around the semiconductor light emitting element.
