    Abstract: A light source includes a semiconductor light emitting device; and a wavelength converter. The wavelength converter includes: a substrate; a phosphor layer disposed on the substrate; and a light reflective layer disposed on the substrate so as to surround the phosphor layer. The phosphor layer includes phosphor particles and a first matrix material in which the phosphor particles are dispersed. The light reflective layer includes inorganic compound particles and a second matrix material in which the inorganic compound particles are dispersed. The inorganic compound particles have a refractive index higher than that of the first matrix material. The first matrix material has a refractive index higher than that of the phosphor particles. The phosphor particles have a refractive index higher than that of the second matrix material.
