SOLAR REFLECTING AND CONDENSING DEVICE USING THIN FILM

摘要

A film solar reflecting and condensing device includes: a condensing film (2), a surface form baseplate (3) and a focusing bracket (4) of the surface form, wherein the condensing film (2) is a planar film (2a) with reflecting plating which is set on the top surface of the surface form baseplate (3); the surface form baseplate (3) is a thin plate whose bottom surface is attached to the top surface of the focusing bracket (4) of the surface form and reproduces its surface shape; the focusing bracket (4) of the surface form includes: a top optical curved surface (4a) of the focusing bracket (4) of the surface form and a focusing structure (4b) integrated with the focusing bracket of the surface form, wherein the top optical curved surface (4a) of the focusing bracket of the surface form is on the top surface of the focusing bracket (4) of the surface form and the central point of the focusing structure (4b) integrated with the focusing bracket of the surface form is at the focus (f) of the top optical curved surface (4a) of the focusing bracket of the surface form.
