Abstract
A circuit arrangement for operating a high pressure discharge lamp includes input terminals for connection to a supply voltage source, lamp connection terminals for connection of the lamp, and a power supply coupled to the input terminals. The power supply provides a current to the lamp in the form of successive periods of current and includes a pulse generating element for generating a current pulse superpositioned on the periods of the current to the lamp. The pulse generation element is synchronized with an image writing signal.
