FIELD: physics.
SUBSTANCE: semiconductor light-emitting device comprises the first wavelength-converting element positioned on the upper light-emitting surface of the semiconductor light-emitting device. The first wavelength-converting element comprises the first wavelength-converting material that is not wider than this upper light-emitting surface; and the second wavelength-converting element positioned on the side surface of the semiconductor light-emitting device. The second wavelength-converting element comprises the second wavelength-converting material that does not extend to the upper light-emitting surface. The first and the second wavelength-converting materials are different wavelength-converting materials.
EFFECT: increasing the efficiency of the device.
