Abstract
The invention provides a reflective sheeting material having a structured reflective surface having a linear ray of isosceles prism reflecting elements, each element including a pair of reflective surfaces at an angle of about 120 DEG therebetween. The invention also provides a reflective sheeting material having a structured reflective surface comprising an array of reflecting elements each comprising a polyhedron having three parallelogram faces. The invention also provides an apparatus such as a light pole for transporting light and reflecting the light in a broad, uniform pattern. The apparatus comprises (a) a columnar light conduit, for transporting light therealong, the conduit having a proximate end and a distal end; (b) a light source provided at the proximate end of the light conduit, and (c) a light distributing reflective member, such as the reflective sheeting material described above, comprising a multiplicity of repeating reflecting elements. The reflective member is positioned at the distal end of the light conduit so that the light exiting the distal end of the conduit is reflected in a broad, uniformly distributed pattern.
