Abstract: A method of fabricating an elongate light guide includes providing a moving mold assembly with at least two mold parts, wherein the mold parts have an engaged portion and a non-engaged portion. The mold parts are moved such that the non-engaged portions move in a first direction and the engaged portions move in a second direction different from the first direction to form an elongate regenerated mold cavity having a longitudinal axis, wherein the cavity comprises a molding surface with at least one structure transverse to the longitudinal axis. A thermosettable material is introduced into the cavity and at least partially polymerized in the cavity to form a light guide therein. The light guide is then removed from the mold assembly.

Abstract: An illumination device produces a desired illumination pattern by tailoring the configuration of individual light extraction structures. At least two of the light extraction structures have different configurations from one another. The illumination device includes a light guide having a light guide core and an optically smooth surface for propagating light through the core. A light emitting region extends along a portion of the core and includes a plurality of light extraction structures distributed along the optically smooth surface. The light extraction structures are configured so that light reflected therefrom is emitted from the light guide through the optically smooth surface.

Abstract: An illumination system comprises a light source optically coupled with an optical fiber. The optical fiber includes a light emitting region extending along a portion of its length. The light emitting region includes a plurality of optical elements disposed about a first longitudinal axis extending along the surface of the optical fiber and a plurality of optical elements disposed about a second longitudinal axis extending along the surface of the fiber. The second longitudinal axis is displaced from the first longitudinal axis. In use, light from the light source is injected into the optical fiber and propagates along the fiber according to Snell's law. A portion of the light propagating through the fiber becomes is reflected from the optical elements and is extracted from the fiber.
