METHOD OF CALIBRATING A SYSTEM COMPRISING A GAS-DISCHARGE LAMP AND A COOLING ARRANGEMENT

摘要

The invention describes a method of generating calibration data (ΔUx, CPx) for a system (3) comprising a gas-discharge lamp (1) and a cooling arrangement (2) for cooling the lamp (1), which method comprises the steps of establishing a correlation (RP-U) between a lamp operating parameter delta (ΔU) and a lamp cooling status parameter delta (ΔP, ΔB); and associating a cooling arrangement control parameter (CP, CPx) with a lamp operating parameter delta (ΔU) on the basis of the established correlation (RP-U). The invention also describes a method of calibrating a cooling arrangement (2) of a system (3) comprising a gas-discharge lamp (1) and a cooling arrangement (2) for cooling the lamp (1). The invention also describes a method of controlling a cooling arrangement (2) in a system (3) comprising a high-pressure gas discharge lamp (1). The invention further describes a system (3) comprising a high-pressure gas discharge lamp (1); a cooling arrangement (2) for cooling the lamp (1), which cooling arrangement (2) is calibrated using the calibration method according to the invention; and a cooling arrangement controller (33) for controlling the cooling arrangement (2) using the control method according to the invention.
