Embodiment Construction

[0028] figure 1 The structure of the helical pulse generator 1 is shown in plan view. The helical pulse generator comprises a ceramic cylinder 2 into which two different metallic conductors 3 and 4 are helically wound as foil strips. The cylinder 2 is hollow inside and has a given inner diameter ID. The two inner contacts 6 and 7 of the two conductors 3 and 4 lie approximately opposite each other and are connected to each other via a spark arrestor 5 .

[0029] Only the outer conductor of the two conductors has another contact 8 at the outer edge of the cylinder. The other conductor ends open. Thus, the two conductors together form a waveguide in a dielectric medium (ceramic).

[0030] Helical pulse generators are wound from two ceramic discs coated with metal paste or constructed from two metal discs and two ceramic discs. An important characteristic parameter here is the number of turns n, which should preferably be in the order of magnitude of 5 to 100. The winding ar...

Abstract

A spiral pulse generator is used to start a high-pressure discharge lamp and is accommodated directly in the external bulb of the lamp. The spiral pulse generator comprises two parts which are manufactured jointly as an LTCC component.

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...
