Abstract: A lighting system utilizing an optical fiber is provided. In the preferred embodiment of the present invention, light rays from a light source are focused into an outer end of the optical fiber wound in a spiral shape. The light rays are focused in by a ball lens. In one embodiment, the spiral shape optical fiber is enclosed by a casing having a reflective inner surface along the periphery and the bottom; however, there is an aperture in the casing to permit light rays from the light source to reach the outer end of the spiral shape optical fiber.
