<p>An adjustable transmissive insulative array of vanes comprising a plurality of parallel longitudinally extending and transversely spaced vanes, each vane rotatable about its longitudinal axis between an insulative state and a transmissive state, each vane comprising an insulative body and a reflective layer on the outer surface of the body, the insulative body of each vane shaped such that in the insulative state the vane is operable to engage with adjacent vanes to form a substantially continuous insulating boundary, the insulative body of each vane further shaped such that in the transmissive state the vane cooperates with an adjacent vane to form an optical concentrator therebetween comprising a portion of the reflective layer of the vane and an portion of the reflective layer of the adjacent vane, each optical concentrator operable to transmit received light through the array of vanes.</p> |
