发明名称 LIGHT EMITTING DEVICE
摘要 According to one embodiment, a light emitting device includes a light emitting element, a molded body, a first sealing layer, and a converging lens. The light emitting element has a first surface and a second surface opposite to the first surface, with an optical axis of emission light being perpendicular to the second surface. The molded body includes a recess. The first surface side of the light emitting element is disposed in the recess. The first sealing layer covers the light emitting element in the recess and includes a first transparent resin and phosphor particles. The converging lens is provided on an upper surface of the first sealing layer and has a refractive index increasing with increase of distance from the optical axis. The refractive index at a position in contact with an outer edge of the upper surface of the first sealing layer is higher than a refractive index of the first transparent resin.
