DEVICE FOR REFLECTING ELECTROMAGNETIC WAVES, PARTICULARLY LIGHT AND HEAT RADIATION TO A REGULABLE EXTENT, AND METHOD FOR THE METALLIZATION OF A FILM WITH A DENSITY VARYING WITH LONGITUDINAL POSITION ACCORDING TO A GIVEN FUNCTION

摘要

The present invention relates to a kind of devices, for reflecting (1) electromagnetic wave, adjustable range is arrived in especially light and heat radiation, wherein the device (1) in the substantial transparent electromagnetic wave of two protective plates (3) include a sheet-like flexible reflecting element (2) and the similar bigger length of width and protective plate (3) send electromagnetic wave to some extent and/or in different ways device (1) further include on the longitudinal direction of driving method (4) across reflecting element (2) protective plate (3) and by it in same direction. Protective plate (3), which is connected with each other, is provided with protective plate (3) in the confined space to close between confined space (2) and reflecting element. The present invention also relates to a kind of metallized films to have the function of that density is given with basis in lengthwise position.
