Abstract:
A semiconductor light emitting device includes a semiconductor light emitting element that emits light of a first wavelength, at least two kinds of phosphors that absorb the light of the first wavelength and then emit wavelength-converted light, sealing resin in which the at least two kinds of phosphors are dispersed and the semiconductor light emitting element is embedded, and binder resin. Combined bodies in which the at least two kinds of phosphors are combined by the binder resin are dispersed in the sealing resin.
