Abstract: A semiconductor light emitting device includes a light emitting chip that includes a semiconductor layer at a first surface. A transparent film is provided on the semiconductor layer and forms an interface therewith. A phosphor resin layer, including a resin and a phosphor, is provided on the transparent film. A refractive index of the transparent film is greater than a refractive index of the semiconductor layer.

Abstract: A light emitting device includes a light emitting element disposed on a portion of a first lead frame element, a first resin including a fluorescent material, and a second resin. The first resin is above the light emitting element. The second resin is between the first resin and the first lead frame element. In some embodiments, the second resin includes a filler material that reflects light emitted by the light emitting element. In some embodiments, the light emitting device includes a protective diode connected in reverse parallel with the light emitting element. In some embodiments, a transparent resin may be disposed first and second resins.
