Problems solved by technology

However, it cannot be implemented because on the one hand it is too expensive
On the other hand, its advantage of being installed in the lamp cap is not sufficient, because there is still the problem of delivering high voltage to the bulb
Therefore, the probability of lamp damage (insulation problem or a break in the lamp cap) is greatly increased
Ignition equipment commonly used today usually cannot be heated above 100°C

Embodiment Construction

[0030] figure 1 The principle 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 wound helically as film strips. The cylinder 2 is hollow on the inside and has a given inner diameter ID. The two inner contacts 6 and 7 of the two conductors 3 and 4 lie as closely as possible parallel to each other and are connected to one another via a spark gap 5 .

[0031] Only the outer conductor of the two conductors has a further contact 8 at the outer edge of the cylinder. The other conductor terminates openly. Thus, the two conductors together form a waveguide in the dielectric medium (ceramic).

[0032] The helical pulse generator is wound from two ceramic membranes coated with metal paste or consists of two metal membranes and two ceramic membranes. An important characteristic quantity here is the number of turns n, which should preferably be in the or...

Abstract

A high-voltage pulse generator acting as a transformer is used to start a high-pressure discharge lamp.

Description

technical field [0001] The invention is based on a high-voltage pulse generator according to the preamble of claim 1 . Such generators can be used in particular to light high-pressure discharge lamps for general lighting or photographic purposes or in vehicles. Furthermore, the invention relates to a high-pressure discharge lamp having such a generator. Background technique [0002] The problem of starting high-pressure discharge lamps is currently solved by integrating the starting device into the ballast. The disadvantage is that the feeder must be designed to withstand high voltage. [0003] In the past, repeated attempts have been made to integrate the ignition unit into the lamp. Attempts have been made here to integrate the ignition unit into the lamp base. A particularly effective and high-pulse ignition is achieved by means of a so-called helical pulse generator, see US Pat. No. 3,289,015. Such devices have long been proposed for use in various high-pressure dis...
