METHOD FOR OPERATION OF A HIGH PRESSURE DISCHARGE LAMP OPERATING DEVICE FOR A HIGH PRESSURE DISCHARGE LAMP AND HIGH PRESSURE DISCHARGE LAMP WITH AN OPERATING DEVICE

摘要

The invention relates to a method and a device for operation of ah high pressure discharge lamp with a low-frequency current of alternating polarity, whereby the high pressure discharge lamp is operated during a start phase at a higher power than the rated power thereof. According to the invention, the high pressure discharge lamp is provided with a current, at least during the start phase, with a commutation time of less than or equal to 40 microseconds.
