1. A solid-state light source for providing light, the solid-state light source comprising:

  • a semiconductor light source for emitting light;

    a fiber optic element coupled to the semiconductor light source, the semiconductor light source and the fiber optic element in aggregate providing an illumination path, wherein the fiber optic element comprises a fiber optic line having an input at a proximal end for receiving emitted light from the semiconductor light source and an output at a distal end for emitting light through a distal end of the fiber optic element, the output being configured to emit light in a direction substantially parallel to a longitudinal axis of the fiber optic line;

    a phosphor layer located along the illumination path, wherein the phosphor layer does not contact the semiconductor light source; and

    a clear material covering the semiconductor light source, wherein the phosphor layer also does not contact the clear material,wherein the semiconductor light source includes a light emitting diode configured to emit a non-white light, and wherein the phosphor layer is configured to receive the non-white light and convert the received light to white light.
