Abstract (en)
[origin: WO2006111269A1] The following steps are carried out for the regulation of the operation of a fluorescent lamp powered by an AC voltage: controlled superimposition of a DC voltage on the fluorescent lamp, recording the lamp voltage for the fluorescent lamp and analysis of the lamp voltage as input parameter for the regulation of the lamp power. The DC component and optionally other parameters of the lamp voltage are analyzed.
