Abstract (en)

[origin: WO2008055366A1] A method for operating a UV lamp (8) comprising the following steps: - a converter (1) produces a bipolar feed voltage, current-limiting means (13) being provided, - the converter (1) is fed from the supply system and it produces an adjustable bipolar feed voltage with a pre-selectable adjustable frequency, both of which can be predetermined by an electronic controller (14), - an ignition operation (B, D) is introduced on the lamp (8) and the ignition (D) is monitored by the controller (14), - after the ignition (D) there follows a run-in phase (D, E), in which at least one of the parameters: temperature, voltage and current is detected by the controller (14) and the bipolar feed voltage and/or its frequency is adjusted using the converter (1) in such a way that the lamp parameters are maintained, - then the desired lamp power is predetermined for achieving operation readiness (E, F) by means of varying the frequency or the voltage for the purpose of adjusting the desired lamp power for the following operating phase (G, H).
