Transparent composite disk for e.g. windscreen, of vehicle, has heating element provided with low-impedance conducting elements e.g. wires and/or printed conducting paths, in surface area not heated by coating and on surface of coating
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.
