Abstract
Radiant energy screens are constructed as louvred screens, with the louvre elements each having second-surface retro-reflective elements on or in their outwardly facing surfaces. The inwardly facing surfaces of the louvre elements may be highly reflective to reduce their emissivity. The reflecting surfaces of the retro-reflective elements may be, inter alia, inclined elongate reflectors, cube-corner reflectors, or lens and mirror combinations.
Claims11
A radiant energy screen bounded by, inter alia, an imaginary outer surface and an imaginary inner surface, said screen comprising a plurality of slats, each slat being lamellar and of elongate form, characterized in that:
- (a) each slat has a plurality of retro-reflective structures embodied within the slat;
- (b) the retro-reflective structures incorporate a body of material which is transparent to radiant energy, the outer surface of said body of transparent material forming one face of the structures;
- (c) each slat, in use, is inclined at an angle relative to the said imaginary outer surface.
