A radiant energy redirecting system comprising a radiant energy transmitting body structure; the structure 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 the energy into the interior of the perimeter, an exit face to pass the energy to the exterior of the perimeter in a direction towards the reverse side of the body from the side of the incidence, and a Totally Internally Reflecting face angled relative to the entry and exit faces to redirect towards the exit face the radiant energy incident from the entry face; the body structure generally redirecting incident radiant energy towards a predetermined target zone situated apart from and on the reverse side of the body relative to the side of the incidence; and lens structure associated with at least one of the faces for redirecting radiant energy passing between the entry and exit faces via the Totally Internally Reflecting face.
