1. An LED lighting arrangement, comprising:

  • an elongate optical component comprising a transparent material, and a layer containing a diffusing material, a first photoluminescent material, and a second photoluminescent material mixed together, wherein the diffusing material is light diffusive and the first and second photoluminescent materials are excitable by light of a first wavelength range and emit light of a second and third wavelength range respectively, and wherein the optical component has a hollow form; and

    an LED assembly that is operable to generate the light of the first wavelength range, wherein the optical component is separated from the LED assembly,wherein the optical component is mounted to the LED assembly to form the LED lighting arrangement, and wherein the LED lighting arrangement is operable to emit white light comprising a combination of light emitted by the LED assembly and light emitted by the first and second photoluminescent materials.
