摘要： A light-emitting device includes a base and a light-emitting element that is disposed on the base. The light-emitting element is made up of a plurality of semiconductor layers including a light-emitting layer, and at the same time, is covered with a wavelength converting portion that includes a wavelength converting material. The light-emitting layer emits primary light, and the wavelength converting material absorbs part of the primary light and emits secondary light. The luminance of the primary light emitted from the edge portion of the light extraction surface of the light-emitting device is higher than the luminance of the primary light emitted from the inner region located inside the edge portion, and the ratio of the primary light and the secondary light that are emitted from a light extraction surface of the wavelength converting portion is substantially uniform across the light extraction surface of the wavelength converting portion. Thereby, a light color difference across the light extraction surface of the wavelength converting portion that covers the light-emitting element can be reduced further, and it is possible to irradiate an irradiation surface with light of uniform color.

The phosphor layer has an outer edge of a cross section taken in a direction parallel to the principal surface of the substrate having a substantially circular shape or a substantially regular polygonal shape having five or more sides. An outer edge of the principal surface of the substrate is formed in a substantially circular shape or a substantially regular polygonal shape having five or more sides. With this configuration, light obtained therefrom has less non-uniformity in color and a high luminous flux can be realized.
