Abstract: A light emitting device includes a mounting board, a light emitting element, first and second light reflecting members, a light transmissive member, and a sealing member. The first light reflecting member surrounds a lateral surface of the light emitting element while a top surface is exposed. The second light reflecting member surrounds an outer periphery of the light emitting element, and is in contact with the first light reflecting member with at least a part of the second light reflecting member being positioned higher than the first light reflecting member. The light transmissive member includes a wavelength conversion substance, and is disposed inside the second light reflecting member and positioned higher than a lower surface of the light emitting element. The sealing member covers the second light reflecting member and the light transmissive member. An outer edge of the sealing member coincides with an outer edge of the mounting board.

Abstract: A light-emitting device includes a base, a light-emitting element, and reflecting elements. The light-emitting element is mounted on the base. The reflecting elements are arranged around the light-emitting element to reflect light emitted by the light-emitting element. Each of the reflecting elements includes a core and a dielectric multilayer film. The dielectric multilayer film covers the core and has a thickness to reflect a wavelength of the light emitted by the light-emitting element.
