发明名称 LIGHT EMITTING DEVICE AND ILLUMINATION APPARATUS USING SAME
摘要 A light emitting device includes a solid-state light emitting element; a substrate mounted with the solid-state light emitting element; and a wavelength converting member covering an emission surface of the solid-state light emitting element, the wavelength converting member being formed of a transparent resin containing a fluorescent material. The wavelength converting member includes a first fluorescent material layer provided around the solid-state light emitting element, the first fluorescent material layer being substantially equal in height to an upper surface of the solid-state light emitting element, and a second fluorescent material layer provided to cover the solid-state light emitting element and the first fluorescent material layer, and wherein the second fluorescent material layer is higher in fluorescent material concentration than the first fluorescent material layer, the first fluorescent material layer having a lateral surface exposed and not covered with the second fluorescent material layer.
