ABSTRACT:
The present invention provides an apparatus for transporting and distributing light. The apparatus comprises a longitudinal, hollow light conduit with a linear array of prisms arranged side-by-side to form grooves, the grooves disposed in a non-parallel orientation with respect to the longitudinal axis of the light conduit. The non-parallel orientation of the grooves causes some, or all, light which would otherwise be totally internally reflected within the light conduit to be emitted from the light conduit.
