Abstract:
1. A light-emitting device comprising a base, and a light-emitting element that is disposed on the base and that emits primary light, wherein the light-emitting element comprises a plurality of semiconductor layers including a light-emitting layer, the light emitting element is covered with a cover portion that includes a higher refractive index portion having a refractive index higher than that of an other portion of the cover portion, the higher refractive index portion being located at an outer circumferential portion of the cover portion, the cover portion is covered with a wavelength converting portion that includes a wavelength converting material that absorbs part of the primary light and emits secondary light, and a part of the primary light emitted from the light-emitting element passes through the other portion of the cover portion and then through the higher refractive index portion before entering the wavelength converting portion.
