    摘要: A method of generating a measuring signal indicating arc straightness in a gas discharge lamp (L) comprises the following steps: in a first step, applying a first lamp current (IN) to the lamp; in a second step, adding a brief pulse current (Ip) to the first lamp current (IN), allowing the lamp voltage to regain a steady state, and measuring the resulting average value of the lamp voltage (V2) in this steady state; generating a measuring signal indicating arc straightness on the basis of said average lamp voltage (V2) measured in the second step.
