Patent ID: 8616715

Claim:
A remote light wavelength conversion device for converting a source light emitted from a light source within a source wavelength range into a converted light within a converted wavelength range, the remote light wavelength conversion device comprising: a waveguide including a first end and a second end opposite the first end; and a conversion material to convert the source light transmitted through the waveguide to the converted light at the second end; wherein the source light is transmitted from the first end of the waveguide to the second end of the waveguide; wherein the conversion material is applied to the second end to form a conversion coating; wherein the conversion coating includes a plurality of conversion coatings, each one of the plurality of conversion coatings corresponds to a desired output color; and wherein the plurality of conversion coatings is selectable to convert the source light into the converted light with the desired output color defined by a chromaticity; and wherein the waveguide is a fiber having a core diameter of less than about ten micrometers.
