A kind of excimer lamp and manufacturing method of excimer lamp

Abstract

The invention provides an excimer lamp and a manufacturing method of the excimer lamp. The front end of the outer tube is narrowed to form a front neck position, the rear end is narrowed to form a back neck position, the ends of the front neck position and the back neck position are sealed, and the inner tube is sealed. The two ends of the outer tube are placed on the front neck position and the back neck position, the interior of the outer tube is filled with luminescent gas, the outer circumference of the outer tube is provided with an outer electrode, the interior of the inner tube is provided with an inner electrode, the front end of the inner electrode is connected to a conductor, and the conductor starts from The front ends of the inner tube and the outer tube are drawn out. The excimer lamp and the manufacturing method of the excimer lamp form a front neck position and a back neck position at both ends of the outer tube, and the inner tube is fixed and limited by the front neck position and the back neck position, so that no matter in the process of processing or During use, stress and cracks will not be formed at the joint of the inner tube and the outer tube due to uneven heating. Under the premise of realizing the dual dielectric barrier discharge function, the inner tube and the outer tube need not be consolidated together, and the defects of the traditional excimer lamp can be overcome. The product is more reliable and its service life is increased.

Description

technical field [0001] The invention relates to the technical field of ultraviolet lamps, in particular to an excimer lamp and a manufacturing method of the excimer lamp. Background technique [0002] When the two electrodes are filled with xenon, krypton, argon and other inert gases or a mixture of these inert gases and halogen elements, and a high-frequency high voltage is applied between the two electrodes, and when the voltage is higher than the breakdown of the gas between the electrodes When the voltage is applied, the gas between the poles will be ionized to form a plasma, and an uneven filamentary discharge will be formed between the two poles and emit light. This luminous effect does not occur the natural absorption of radiation, the luminous efficiency is very high, and the monochromaticity is good. However, the unstable and uniform discharge limits its application. It was later found that when an insulating medium was inserted between the two electrodes, the dis...

AI Technical Summary

Problems solved by technology

In this way, due to uneven heating during the processing and use of the inner and outer pipes, the junction of the inner and outer pipes (point A) is prone to stress and cracks, which requires high processing technology and is difficult to process.

During the use of the lamp tube, the junction of the two tubes will also cause cracks due to the conduction and accumulation of ultraviolet light along the glass bulb, resulting in ultraviolet degradation
