Abstract
A heating element including a current conductor through which electric power is conducted and electricity converted into heat by a voltage drop across an ohmic resistor. The heating element is a planar or a strip-shaped structure and is provided with at least one support layer and an adhesive layer, while the current conductor is designed as an additional, current-conducting layer which is arranged between the support layer and the adhesive layer. The support layer, the current-conducting layer, and the adhesive layer are transparent.
Claims34
A heating element having a current conductor for conducting electrical current, wherein, as a result of a drop in voltage at an ohmic resistor, the current is converted into heat,
- wherein the heating element is a planar structure in form of a tape having at least one backing layer and an adhesive layer,
- the current conductor is formed as a current-conducting layer,
- the current-conducting layer is disposed between the backing layer and the adhesive layer, and
- the backing layer, the current-conducting layer, and the adhesive layer are transparent.
