Abstract:
A light emitting device includes a light emitting element, a sealing member, and a first film. The light emitting element has a light emitting surface from which a light is emitted. The sealing member is provided on the light emitting surface of the light emitting element to cover the light emitting surface and having a light output surface via which the light is output from the sealing member. The light output surface being curved to have a concave shape. The sealing member includes a light-transmissive material containing a fluorescent material to convert a wavelength of the light emitted from the light emitting element. The first film is disposed on a part of the light output surface of the sealing member to partially reflect the light emitted from the light emitting element.
