ABSTRACT:
A reflective-refractive lighting jacket has a first reflective and second refractive surface for surrounding a tubular light source in the interior of the jacket. A first reflective section reflects light from the source, and a second refractive section transmits light from the source and from the reflecting section. Both sections are forms in cross section that have a focal point in the interior of the jacket. Flutes in the jacket create various images and projected beams so that many different images and projected lines of the source are formed to provide for distributing light while minimizing actual diffusion.
