ABSTRACT:
Method and apparatus for forming hollow tubular light-distributing tubes for area illumination along the length of the tubes from a beam of light introduced into one end. Within the tube is a geometrically complex, 3-dimensional light redirecting structure traversing the light beam along the full length of the tube to redirect the light beam proportionately along the length of tube through a window formed therein. Both the tube and the light-redirecting structure can be formed as an integrated flat, substantially void-free structure for shipping and then converted in situ to the operative, 3 dimensional configuration.
