1. An elongated light-producing arrangement comprising:

  • a light source for emitting light;

    an elongated tube having a hollow interior, said tube having a light-transmissible portion extending along the length of said tube and extending only partially around the circumference of said tube, said tube also having a reflective surface for propagating light within and along the axis of the tube, said light source being arranged outside of said tube so as to expose said interior to the light emitted from said light source for reflection by said surface;

    a diffusing medium arranged in said tube extending longitudinally and only partially around the circumference of said tube, substantially diametrically opposite said light-transmissible portion, to diffuse light striking said diffusing medium both directly and by reflection from said reflective surface, said light-transmissible portion, said diffusing medium and said reflective surface in the aggregate extending over substantially the entire surface of said tube, whereby light in said tube impinging on said diffusing medium causes light from the diffusing medium to pass outwardly through said light-transmissible portion.
