1. A light arrangement, comprising:
- an elongated solid-state light source having multiple elongate arrays of solid-state light emitters; and
a hollow elongated optical component having an interior volume, the hollow elongated optical component comprising multiple wavelength conversion regions having a first region that corresponds to a first color temperature and a second region that corresponds to a second color temperature, the first region corresponding to a first elongated array of solid-state light emitters and the second region corresponding to a second elongated array of solid-state light emitters;
wherein the multiple wavelength conversion regions project into the interior volume of the hollow elongated optical component;
wherein an emission product of the light arrangement is a combination of first region emissions generated by the first region, second region emissions generated by the second region, and light source emissions generated by the elongated solid-state light source; and
wherein the elongated optical component is an integrally formed component having the multiple wavelength conversion regions and a diffuser portion.
