Problems solved by technology

The disadvantage of this ultraviolet discharge lamp is that when a vacuum discharge occurs, the inert gas in the ion state will react with the inner wall of the glass lamp tube to release impurity gas, thereby changing the output spectrum of the ultraviolet discharge lamp and attenuating the output energy. Reduced service life of UV discharge lamps

Abstract

The invention discloses an ultraviolet discharge lamp, which comprises a lamp tube, an output window, a first electrode, a second electrode, a ceramic tube, a first electrode holder and a second electrode holder, wherein the ceramic tube is arranged in the lamp tube; the first electrode is arranged at the outer side of one end, close to the output window, of the ceramic tube; and one end, close to the second electrode holder, of the first electrode holder and / or one end, close to the first electrode holder, of the second electrode holder are / is coated with an insulating structure. The ultraviolet discharge lamp has the beneficial effects that the insulating structure coating the first electrode holder and / or the second electrode holder is adopted by the ultraviolet discharge lamp; and breakdown voltage between the first electrode holder and the second electrode holder is increased, so that the possibility of glow discharge between the first electrode holder and the second electrode holder is greatly reduced; the operating life of the ultraviolet discharge lamp is prolonged; and the stability of the ultraviolet discharge lamp is improved.

Description

technical field [0001] The invention relates to the technical field of gas analysis and detection instruments, and more specifically relates to an ultraviolet discharge lamp. Background technique [0002] In the prior art, an ultraviolet discharge lamp usually includes a sealed cylindrical glass lamp tube filled with a low-pressure inert gas or an inert gas mixture. One end of the glass tube is hermetically bonded to a transparent output window for vacuum ultraviolet (VUV) transmission. One of the electrodes (negative electrode) is arranged inside the glass lamp tube, the other electrode (positive electrode) is arranged outside the glass lamp tube, and the two electrodes are respectively connected to the power supply. Under the excitation of an external electric field, the inert gas in the lamp tube undergoes glow discharge to generate vacuum ultraviolet rays, which are transmitted through the output window. The disadvantage of this ultraviolet discharge lamp is that when ...
