Abstract (en)
[origin: WO2008055544A1] The invention relates to a circuit arrangement for operating a high-pressure discharge lamp (14), comprising an electronic ballast that is designed to feed an AC supply signal to the high-pressure discharge lamp (14), the AC supply signal having a minimum frequency of 1MHz. The electronic ballast is also designed to modulate the amplitude of the AC supply signal. The invention further relates to a method for operating a high-pressure discharge lamp (14) by means of an AC supply signal which has a minimum frequency of 1 MHz and the amplitude of which is modulated.
