发明名称 LIGHT EMITTING DEVICE
摘要 A light emitting device includes a housing member having a recess open upward, a light emitting element arranged in the recess and having a light emitting layer of a semiconductor, and a wavelength converting member arranged in the recess and capable of absorbing a part of light emission from the light emitting element and emitting light of different wavelength. The light emitting device is capable of mixing the light emission from the light emitting element and the light emission from the wavelength converting member to emit light from the opening of the recess. A light scattering surface for scattering light emission from the light emitting element and wavelength converting member is formed on at least part of the side surface of the recess. The light emitting element and the wavelength converting member are spaced apart from the side and bottom surfaces of the recess, and the side surfaces of the light emitting element are exposed without being covered with the wavelength converting member.
