Abstract: A method and a circuit arrangement for the operation of a high-pressure gas discharge lamp (HID [high intensity discharge] lamp or UHP [ultra high performance] lamp) is described, which lamp is particularly suitable for illuminating projection displays with sequential color rendering (for example LCOS or SCR-DMD systems) with a pulsatory lamp current. Artefacts in the color rendering are avoided through the generation of at least one compensation pulse of a given amplitude and a given timing and through superimposition thereof on the lamp current.

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.

Abstract: The high-pressure discharge lamp comprises a lamp vessel (1) in which an anode (4) and a cathode (5) are disposed spaced apart by an electrode distance D of 1-2 mm, the anode (4) having a tip (9) with a blunt end surface S. The area of the end surface S in mm2 and the lamp current I in amperes satisfy a relationship according to which 0.09
