<p>A reflector arrangement, especially for solar collectors, having a sheet (3) of reflecting material which is stretched to radiation-concentration shape in an airtight covering (1) of at least partly transparent material in that it divides the covering into two chambers (7, 8) within which different air pressures are maintained. The air pressures also maintain the covering (1) stretched around the sheet (3). The sheet (3) preferably is secured in a rigid frame (5) which, in turn, is connected to the covering (1). Radiation incident upon the sheet (3) is concentrated to a small area within which a radiation absorber is provided. The reflector arrangement is very easy to manufacture and also is inexpensive and can be quickly mounted, also by unskilled persons. </p> |
