Gas discharge lamp and apparatus for its temperature

The present invention firstly relates to a device for the controlled tempering of a gas discharge lamp; For example, for the controlled heating of amalgam reservoir (22) of a low pressure mercury vapor lamp. The invention further relates to a gas discharge lamp. the device is designed according to the invention comprises a transformer core (11) of a transformer (14), wherein the transformer core (11) for receiving at least one of a discharge current-carrying line (04; 06) of the gas discharge lamp as the primary winding (13 12). The transformer (14) constitutes a power source for heating of a function of the gas discharge lamp function-determining region (22) of the gas discharge lamp. The device further comprises a secondary winding (16) on the transformer core (11) and a means for temperature control (19) which serves heated energy for controlling the functional area (22). The means for temperature control (19) is electrically connected to the secondary winding (16).
