Problems solved by technology

[0009] The discharge lamps described here also lead to the generation of auxiliary discharges and thus corrosion of the molded body at the aperture.
This results in a significant reduction in the intensity or life of the gas discharge lamp
Furthermore, the above-mentioned discharge lamps are expensive to assemble

Embodiment Construction

[0022] FIG. 1 shows a xenon lamp 1 with a cathode space 28 which completely surrounds a cathode 10 . The cathode space 28 is part of the housing base 14 which additionally includes the housing front end 16 and the housing partition 22 . In addition, the cathode 10 and the anode 12 are located inside the xenon lamp 1 . When the xenon lamp 1 is in operation, a discharge is formed between the cathode 10 and the anode 12, which discharge provides a continuous UV spectrum. To increase the UV intensity, the discharge is narrowed through the molded body 18 . This significantly increases the concentration of the charge carriers inside the molded body 18 and produces a point-shaped light source.

[0023] The cathode 10 is surrounded by a cathode space 28 , wherein the cathode space 28 has a circular opening in the direction of the optical axis of the xenon lamp 1 , which forms a cathode window 30 . In this case, the optical axis is defined by openings in the molded body 18 and in th...

Abstract

The invention relates to a deuterium lamp with a shell base made of an insulated material. The deuterium lamp with the shell base made of the insulated material comprises a bulb, an anode, a cathode and a shell, wherein the bulb is filled with gas, the anode is arranged in the bulb, the cathode is arranged in the bulb and spaced from the anode, the shell is provided with a molded body, a shell rear wall and the shell base, at least a part of the shell base is not conductive, and a shell front end, a shell partition plate, a cathode space and a cathode shielding window are arranged on the shell base. The cathode shielding window is insulated relative to the molded body and / or made of the insulated material. The deuterium lamp is used for analysis.

Description

technical field [0001] The invention relates to a deuterium lamp with a housing base composed of insulating material. Background technique [0002] In the xenon lamps commonly used today, the cathode is surrounded by a metal housing which is at the same electrical potential as the anode space and the molded body. This leads to the formation of auxiliary discharges which, in transparent lamps, lead to mirroring. In addition, the secondary discharge leads to corrosion of the molded body and a reduction in the lamp intensity, since the discharge current can no longer flow completely through the molded body. [0003] In known xenon lamps, the housing consists of a total of six parts, all of which have tolerances and must be welded to one another. Because the tolerances add independently, the series spread is disproportionately large, especially on the front housing parts. Furthermore, it takes a lot of time to assemble this type of xenon lamp. In this case, both the front an...
