Abstract
An illumination device includes a flexible and substantially rod-like member having a predetermined length with a light-receiving surface and a light-emitting surface and an elongated light source extending along and positioned adjacent the light-receiving surface of the rod-like member, such that light entering the rod-like member from the elongated light source and through the light-receiving surface is preferentially scattered, thus causing a light intensity pattern that appears substantially uniform along the light-emitting surface of the rod-like member.
