| 摘要 |
The device according to the present invention consists of transparent plastic material, like polyethylene or other suitable, having incorporated a plurality of layers of dioptric surfaces obtained with vacuoles (2) filled with air or other gas or transparent liquids with a high refraction index, so as to form air or fluid insulation chambers, through structure (1), against the leaking of the heat stored, due to the transparency, from the sunbeams (R) and, at the same time, to form a layer of sunbeam concentrators, consisting of said dioptric surfaces, onto proximal and/or distal focuses (F), according to the curving of the incorporated dioptric surfaces.
