TRANSPARENT PANE HAVING A HEATABLE COATING
First Claim
1. A transparent pane with a conductive coating extending at least over a part of a pane surface of the transparent pane, in particular over a visual field of the transparent pane,wherein the conductive coating is electrically connected to at least two strip-shaped bus bars such that after application of a supply voltage, a current flows over a heating field formed between the at least two strip-shaped bus bars,wherein the conductive coating has an electrical resistance such that upon application of a supply voltage in the range between more than 100 volts and 400 volts, a heating output from the heating field is in a range from 300 watt/m2 to 1000 watt/m2,wherein the at least two strip-shaped bus bars have, at least in sections of the at least two strip-shaped bus bars, a maximum width of less than 5 mm and the width of the at least two strip-shaped bus bars being dimensioned such that a maximum electrical power loss per unit of length is 10 watt/m, andthe at least two strip-shaped bus bars having a specific resistivity in a range from 2 μ

Abstract
A transparent pane with a conductive coating extending at least over a part of the transparent pane surface, in particular over a visual field of the transparent pane is described. The conductive coating is electrically connected to at least two strip-shaped bus bars such that after application of a supply voltage, a current flows over a heating field formed by the conductive coating. The conductive coating has an electrical resistance such that upon application of a supply voltage in the range from more than 100 volts to 400 volts, a heating output from the heating field is in the range from 300 watt/m2 to 1000 watt/m2. The at least two strip-shaped bus bars have a maximum width of less than 5 mm and are dimensioned such that a maximum electrical power loss per unit of length is 10 watt/m. Moreover, the at least two strip-shaped bus bars have a specific resistivity ranging from 2 μohm·cm to 4 μohm·cm.
