1. A semiconductor structure, comprising:

  • a semiconductor light emitting device;

    a first wavelength converting member disposed on a first surface of the semiconductor light emitting device, wherein the first wavelength converting member is no wider than the first surface; and

    a second wavelength converting member on a side surface of the semiconductor light emitting device, wherein the second wavelength converting member does not extend over the first surface;

    wherein the first wavelength converting member comprises a first wavelength converting material in direct contact with the first surface, the second wavelength converting member is different from the first wavelength converting material, and the second wavelength converting material is excitable by light emitted by the first wavelength converting material.
