Abstract (en)
[origin: WO02096163A2] The invention relates to a method for operating fluorescent lamps (1, 16, 25, 36, 47, 52, 53, 74, 82), especially for increasing the service life of fluorescent lamps. The load of at least parts of at least one electrode device (2, 3, 17, 18, 32, 33, 37, 38, 48, 49, 71, 72, 75, 90) of at least one fluorescent lamp exerted by an applied electric current, especially a heating current (I), is reduced by reducing the time load and/or reducing electric power.
