Abstract
Description
technical field
[0001] The invention is based on a high-pressure discharge lamp according to the preamble of claim 1 . Such lamps are in particular high-pressure discharge lamps for general lighting or for photographic purposes. Furthermore, the invention relates to a high-voltage pulse generator which can be used in particular for a lamp. Background technique
[0002] The ignition problem of high-pressure discharge lamps is currently solved by integrating the ignition device into the ballast. The disadvantage is that the feeder must be designed to withstand high voltage.
[0003] Attempts have been made repeatedly in the past to integrate the ignition unit into the lamp. In such cases an attempt was made to integrate the ignition unit into the lamp head. A particularly efficient and high-pulse ignition is achieved by means of so-called helical pulse generators (cf. US-A 3 289 015). Such devices have long been proposed in various high-pressure discharge lamps, such as m...
