A method for operation of at least one low-pressure discharge lamp and operating unit for at least one low-pressure discharge lamp

摘要

The invention relates to a method for operation of at least one low-pressure discharge lamp to an inverter (t1, t2), whereby during the operation of the at least one low-pressure discharge lamp (fl1, fl2) the occurrence of a rectifier effect in at least one lamp (fl1, fl2) is monitored, in order to determine their end of the service life. For monitoring of the equal to the choke effect of the at least one low-pressure discharge lamp (fl1, fl2), the direct voltage drop (u_dc1, U_dc2) via the electrical connections of the at least one low-pressure discharge lamp (fl1, fl2) and the current through the at least one low-pressure discharge lamp (fl1, fl2) evaluated.
