Radiant energy concentration by optical total internal reflection

摘要

A radiant energy redirecting system comprises: (a) a radiant energy transmitting body means, (b) said means comprising multiple elements, each of which acts as a radiant energy redirecting module, having on its cross-sectional perimeter an entry face to receive incidence of said energy into the interior of said perimeter, an exit face to pass said energy to the exterior of said perimeter in a direction towards the reverse side of the body from the side of said incidence, and a Totally Internally Reflecting face angled relative to said entry and exit faces to redirect towards said exit face the radiant energy incident from said entry face, (c) said body means generally redirecting incident radiant energy towards a predetermined target zone situated apart from and on the reverse side of said body relative to the side of said incidence.
