Abstract
A circuit arrangement is provided for operating a fluorescent lamp with a first and a second filament, the circuit arrangement including a heater for the first and the second filament, wherein the circuit arrangement furthermore includes: an apparatus for storing at least one threshold value for at least one operational parameter of the fluorescent lamp; an apparatus for determining the value of the at least one operational parameter; and a control apparatus, which is configured to activate the heater for the first and the second filament for a predeterminable period of time in the event of the at least one threshold value for the at least one operational parameter being exceeded by the determined value of the at least one operational parameter.
Claims11
A circuit arrangement for operating a fluorescent lamp with a first and a second filament, the circuit arrangement comprising a heater for the first and the second filament, wherein the circuit arrangement furthermore comprises:
- an apparatus for storing at least one threshold value for at least one operational parameter of the fluorescent lamp;
- an apparatus for determining the value of the at least one operational parameter;
- and
- a control apparatus, which is configured to activate the heater for the first and the second filament for a predeterminable period of time in the event of the at least one threshold value for the at least one operational parameter being exceeded by the determined value of the at least one operational parameter.
A method for operating a fluorescent lamp with a first and a second filament using a circuit arrangement with a heater for the first and the second filament, comprising:
- a) fixing at least one threshold value for at least one operational parameter of the fluorescent lamp;
- and
- b) in the event of the at least one threshold value being exceeded:
- activation of the heater for the first and the second filaments for a predeterminable period of time.
