Patent ID: 8872210

Claim:
A semiconductor light emitting device comprising: a light emitting element including a semiconductor layer, the semiconductor layer having a first face, a side surface continued from the first face, and an active layer configured to emit an excitation light; an insulating material covering the side surface of the semiconductor layer; a phosphor layer disposed on the light emitting element, the phosphor layer comprising a transparent medium, a phosphor dispersed in the transparent medium, and a particle dispersed in the transparent medium, the phosphor, when excited by the excitation light, emitting a fluorescence, the particle being of a magnitude of not more than 1/10 of a wavelength of the excitation light and having a refractive index that is different from a refractive index of the transparent medium; and a fluorescent reflection film provided between the light emitting element and the phosphor layer, the fluorescent reflection film having a reflectance with respect to a wavelength of the fluorescence emitted by the phosphor that is greater than a reflectance with respect to the wavelength of the excitation light, the fluorescent reflection film being provided between the insulating material covering the side surface of the semiconductor layer and the phosphor layer, wherein a substrate is not provided on the first face, not provided between the first face and the fluorescent reflection film, and not provided between the insulating material and the fluorescent reflection film.
