Abstract:
A light emitting device includes a light emitting element, a molded member, and a sealing member. The light emitting element is arranged on or above the molded member. The sealing member covers the light emitting element. The sealing member contains a phosphor, and a filler material. The phosphor can be excited by light of the light emitting element, and emit luminescent radiation. The filler material contains neodymium hydroxide, neodymium aluminate or neodymium silicate. The filler material absorbs a part of the spectrum of the mixed light of the light emitting element and the phosphor so that the other parts of the spectrum of this mixed light are extracted from the light emitting device.
