Abstract
Description
technical field
[0001] The invention relates to a discharge lamp according to the preamble of claim 1 and a method for producing a discharge lamp according to the preamble of claim 6 . Background technique
[0002] Such a discharge lamp can be configured, for example, as a high-pressure discharge lamp, as described on the Internet home page www.osram.de described above. Such high-pressure discharge lamps are used, for example, in projection systems and searchlights. For the basic design of such lamps see, for example, WO 2006 / 099850 A2 or DE 10 2005030 113 A1.
[0003] Correspondingly, high-pressure discharge lamps have a discharge vessel made of quartz glass with a circular or oval cross-section—also referred to as bulb—in the interior of which two electrodes are formed spaced apart from one another. Two bulb shafts are formed radially on the discharge vessel, in which case the electrode holders are each in contact with the current supply. On the end parts of the two bu...

Embodiment Construction
[0018] The invention is explained below on the basis of an exemplary embodiment of a xenon high-pressure discharge lamp 1 . Such lamps contain absolutely no mercury and are therefore particularly environmentally friendly. However, the invention is not limited to xenon lamps but in other lamp types, for example xenon high-pressure discharge lamps, which are suitable for use in mercury-containing lamps, have a very long operating life and produce light that is very similar to natural light. Therefore, this discharge lamp is best used in projectors, stage spotlights and aircraft headlights.
[0019] The so-called "burner" of the discharge lamp 1 has a discharge vessel 2 made of quartz glass, which has an inner cavity 4 and two radially arranged sealed bulb stems 6, 8, on which bulb stems 6, 8 is respectively provided with lamp cover 10,12. The cap sockets 10 , 12 do not have to be—as in the prior art—designed to be elastic. Two electrodes 14 , 16 formed coaxially with one anot...
