Example Embodiment

[0018] Next, the present invention will be explained based on an embodiment of the xenon-high pressure discharge lamp 1. Such lamps never contain mercury and are therefore particularly environmentally friendly. However, the present invention is not limited to xenon-lamps but in other lamp types, for example, xenon-high pressure discharge lamps suitable for mercury-containing lamps have a very long working life and generate light, making it very similar to natural light. Therefore, this type of 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 composed of quartz glass. The discharge vessel 2 has an inner cavity 4 and two radially arranged sealed tube stems 6, 8 in which the tube stems 6, 8 are respectively provided with lamp caps 10 and 12. The lamp caps 10, 12 do not need to be constructed elastically, as in the prior art. Two electrodes 14, 16 formed coaxially w...

Abstract

The invention relates to a discharge lamp (1) and a method for producing a discharge lamp, wherein a resin layer (38, 40) is present between a piston shaft (6, 8) of a discharge vessel (2) and a base (10, 12) placed thereon.

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...
