Semiconductor light emitting device

The invention relates to a semiconductor light emitting device which can project white light with less uneven shade on the light emitting surface. This device comprises a package with a cavity, a semiconductor light emitting element, and potting resin which is dispersed with at least one phosphor. In particularly, a red phosphor layer is arranged in the cavity for covering the blue LED element. A green phosphor layer and an adhesive resin layer are arranged on the red phosphor layer to form the first potting resin part, and the second potting resin part is arranged on the two. By adjusting the distance from the top surface of the LED element to the top surface of the first potting resin part, the thickness of the second potting resin part, and the distance from the optical axis to the periphery of the top surface of the second potting resin part, the angle can be less than the critical angle of the incident ray from the top center of the semiconductor light emitting element, and the angle is formed by a line,
