Abstract
A backlight comprising a serpentine fluorescent tube nested in a uniquely shaped reflector. Much of the light emitted from the tube is directly emitted to a bounded image plane. The reflector reflects a substantial portion of the rest of the light emitted by the tube to the image plane in such a manner that a very bright and uniform image is formed at the image plane.
