    摘要: Each electrode comprises a shaft (6) and a head (5), the shaft being sealed in a vacuum-tight fashion in each case in an end region (2, 22) of the discharge vessel. At least one electrode is cooled by virtue of the fact that its shaft contains a cooling tube system in which a coolant (11) circulates. Said cooling tube system is surrounded at a spacing by an additional enveloping tube (9, 16), the interspace (10, 20) between the enveloping tube and cooling tube system being fitted with a means of thermal insulation.

    摘要: A short arc high-pressure discharge lamp (1) for dc operation, includes a discharge vessel (2) that has two necks (4) diametrically opposite each other, in which an anode (26) and a cathode (7) made of tungsten are melted in a gastight manner, and which has a filling made of at least one noble gas and possibly mercury. According to the invention, at least the material of the cathode tip (11) contains lanthanum oxide La2O3 and at least another oxide from the group consisting of hafnium oxide HfO2 and zirconium oxide ZrO2 in addition to the abovementioned tungsten.

    摘要: A short-arc lamp (1) with a discharge vessel (2) which contains an anode (3) and cathode (4) which are opposite one another. The filling medium contains inert gases and/or metal vapors, and the anode comprises a body having a front section (11), a substantially cylindrical body (12) and a rear face (13). Provided in the region of the front half of the cylindrical body is a projection (20) whose radial length (X) projects at least 0.5 mm beyond the cylindrical body (12).

    摘要: The high pressure lamp has a bulb (2) to which a neck (4, 4a, 4b) is joined. The transition region (6) between the bulb and the neck is conical. A support tube (5, 20, 25) surrounds a holding rod (10) for an electrode (11) within the bulb. The support tube is melt-connected to the neck, and conical with an inner end of the support tube having an outer diameter which is smaller than the outer diameter of the outer end of the support tube. The neck, likewise, is conical, and forms a transition region to the bulb, which is free from the support tube, so that the support tube is recessed within the transition region. This recess is between 3 and 25 mm and corresponds, at the most, to twice the outer diameter of the support tube at its inner end. The ratio of the outer diameter of the outer, or remote, end of the support tube (5, 20, 25) and the outer diameter of the inner, or proximate, end of the support tube is between 1.1 and 2.5.
