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.
