TRANSPARENT GLASS WITH HEATING COATING

摘要

The disk (1) has an electrically conductive coating (2) extending over an inner edge (4R) of a surface of the disk. The coating is electrically connected with two low-impedance collective conductors (5, 6) such that current flows over a heating field formed by the coating after applying an electrical feeding voltage to the conductors. A heating element (7) is provided with low-impedance conducting elements e.g. wires and/or printed conducting paths, in a surface area not heated by the coating and on a surface of the coating. The conductors are manufactured from metal foils.
