Abstract (en)
[origin: EP1492393A1] The method involves monitoring for the occurrence of a rectifier effect in the low pressure lamp (FL1,FL2) during operation in order to determine the end of its operating life. The voltage drop across the electrical connections of the at least one lamp and the current through the at least one lamp or a proportional value are evaluated to monitor the rectifier effect.. An independent claim is also included for the following: (a) an operating device for operating at least one low pressure discharge lamp.
