Abstract (en)
A transparent window pane (1) comprises a main heating layer (6) and an additional heating layer (8) electrically isolated from each other, a first and a second electrode (11, 12) adapted to be electrically connected to a main power source and electrically connected directly to the main heating layer (6) such that after application of a supply voltage, a main heating current flows through the main heating layer (6) between the first and second electrodes (11, 12), and at least one conducting part (20) adapted to be electrically connected to the main power source or another power source. The conducting part (20) is interrupted by interruption zones (21), whereby the conducting part is formed of a plurality of conducting elements (22) physically separated from each other. Each conducting element (22) is electrically connected to the additional heating layer (8), such that after application of a supply voltage to the conducting part (20), an additional heating current flows through the heating layer (8) in each interruption zone (21).
