Abstract
Light diffusing optical fibers for use in illumination applications and which have a uniform color gradient that is angularly independent are disclosed herein along with methods for making such fibers. The light diffusing fibers are composed of a silica-based glass core that is coated with a number of layers including both a scattering layer and a phosphor layer.
Claims17
A light diffusing fiber for emitting white light comprising:
- a. a core formed from a silica-based glass;
- b. a cladding in direct contact with the core;
- c. a scattering layer in direct contact with the cladding;
- and
- d. a phosphor layer surrounding and in direct contact with the scattering layer, wherein the color of the light emitted, as measured by the CIE 1931 x, y chromacity space, comprises x from about 0.20 to about 0.30 and y from about 0.25 to about 0.35.
