Embodiment Construction

[0008] Quartz glass beads 3 are made by mixing quartz sand, borax, tungsten powder, sodium oxide, aluminum oxide, calcium oxide, barium oxide, etc., stirring evenly, grinding them and sintering them with a hydrogen-oxygen flame at high temperature. The tungsten electrode 2 and the quartz capillary 4 are fused together in the high temperature of the hydrogen-oxygen flame. The sealed quartz lamp tube should be connected to the vacuum system according to the process requirements for exhaust, electrode glow, mercury filling, etc. After the exhaust is qualified, it is separated from the vacuum system. Seal the exhaust pipe at last, and the quartz capillary tube has just been made like this, and the capillary tube of making will be connected to the aging test in the 4500 volt transformer 1.

Abstract

The invention relates to a wolfram rod and quartz direct sealing-type super high pressure capillary mercury lamp in the field of electron vacuum. It can effectively avert the lamp frying and gas leakage. It changes the traditional transition attended mode which adds molybdenum and platinum between the electrode and the lead wire.

Description

technical field [0001] The invention relates to the field of electronic vacuum technology. Background technique [0002] Commonly used ultra-high pressure capillary mercury lamps, the sealing between the electrode and the quartz tube is sealed by a molybdenum-platinum transition method, that is, the sealing surface is molybdenum-platinum and quartz, and the tungsten electrode is connected to the molybdenum-platinum, and the molybdenum-platinum is connected to the molybdenum-platinum. Molybdenum rod lead connection, this complicated connection method, complicated manufacturing process, low pass rate, high cost, it is difficult to adapt to the working conditions under ultra-high pressure. Contents of the invention [0003] The object of the present invention is to provide a capillary quartz lamp tube with simple structure, reliable quality and long life, which can effectively prevent the lamp tube from bursting and leaking. [0004] In order to achieve the above-mentioned p...
