Abstract (en)

[origin: EP2111085A1] The heating circuit has a coupling unit transferring the heat of a primary winding to a secondary winding that is connected to coils (5, 6). A monitoring circuit detects the current flow in the primary winding. A heat control circuit (7) switches the heating circuit into a failure-operation mode if the primary winding current exceeds a threshold value, where the energy transfer of the coupling unit is limited to a value in the mode. An independent claim is also included for a method for heating a coil of a gas discharge lamp.
