METHOD FOR OPERATING A GAS DISCHARGE LAMP OF A MOTOR VEHICLE HEADLAMP |
摘要 |
A method for operating a gas-discharge lamp (10) of a motor-vehicle headlamp comprises steps of operating the gas-discharge lamp (10) in a first operating mode at a comparatively higher power and alternating-current voltage and in a second operating mode in a temporally limiting manner at a comparatively lower power and direct-current voltage. When a switch is made from the first operating mode to the second operating mode, a polarity of the direct-current voltage is predefined depending on the respective polarities of the direct-current voltage in at least one previous operating phase of the second operating mode. A device or unit operates the gas-discharge lamp and controls a sequence of the method.
