| 摘要 |
Embodiments of the present invention utilize inflation air to impart an appropriate shape to a reflective concentrator of a solar collector device. An optical receiver or a secondary optic in communication with an optical receiver may be positioned outside the concentrator's internal inflation space in a plane containing a substantially circular pattern of concentrated reflected illumination. In certain embodiments, the inflation space may be defined between the reflective film having a concave shape, and an optically transparent thin film adopting a convex shape in response to the inflation pressure. In some embodiments the inflation space may be defined between the concave reflective film, and an optically transparent disk having a thickness resisting internal inflation pressure to adopt a planar or only slightly convex profile.
