1. A lighting system comprising:

  • a first helical light-transmitting fiber formed in the shape of a helix, said first helical fiber being doped with a first wavelength converting material, said first helical fiber defining a helical axis; and

    a light-emitting diode (LED) having a light-emitting portion for emitting light of a first color, said LED aligned axially with said first helical fiber, such that a portion of any light emitted by said LED will pass through the open space between the turns of said first helical fiber and a portion of any light emitted by said LED will be received by said first helical fiber and converted to light of a second color.
