High pressure discharge lamp with impulse starter and operational method for a high pressure lamp

摘要

The high-pressure discharge lamp has electrodes arranged inside a discharge vessel which define a discharge path of a gas discharge in the discharge vessel. A starting device is provided and arranged inside the lamp base for the high-pressure discharge lamp and designed as a pulse starting device, for starting the gas discharge in the discharge vessel. Arranged outside its discharge vessel, an auxiliary starting electrode is coupled to the pulse starting device. The voltage input of the pulse starting device is connected in parallel with the discharge path of the high-pressure discharge lamp. The starting capacitor of the pulse starting device is arranged in a DC path connected in parallel with the discharge path of the high-pressure discharge lamp. Connected in parallel with the discharge path is an electric component that is designed as a constituent of a series resonant circuit. A DC isolating capacitor is provided. An independent claim is included for an operational method for a high pressure lamp.
