Wavelength converter and semiconductor light emitting device

摘要

According to an embodiment, a semiconductor light emitting device includes a resin (31) allowing light emitted from a light source to pass through, a plurality of particle-shaped fluorescent substances (32) dispersed in the resin (31), and fillers (35) dispersed in the resin (31) with a particle diameter smaller than the fluorescent substance (32). The fluorescent substances (32) absorb the light emitted from the light source and emits fluorescence having a wavelength different from a wavelength of the light emitted from the light source; and a distribution of the fillers (35) has higher density near the fluorescent substance (32) than a density at a middle position between the fluorescent substances (32) adjacent to each other.
