Abstract:
A light emitting device includes a base, a first light emitting element, a second light emitting element, and a sealing member. The first light emitting element has an active layer of a nitride semiconductor and has a first emission peak wavelength in a blue region. The second light emitting element has an active layer of a nitride semiconductor and has a second emission peak wavelength longer than the first emission peak wavelength of the first light emitting element. The sealing member includes a first region and a second region. The first region contains a phosphor to be excited by light from the first light emitting element. The first region is provided on an element mounting surface. A first upper surface of the first light emitting element is located in the first region. The second region does not substantially contain the phosphor and is provided on the first region.
