Problems solved by technology

[0003] Because traditional pulse lamps mostly use high-purity xenon, it takes a long time for each pulse point to light the lamp, which affects the service life of the lamp tube.
Moreover, because the electrodes mostly use barium tungsten, most of the spectra are above 400 nanometers, and the bactericidal effect is weak

Embodiment Construction

[0013] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] Such as figure 1 , figure 2 The shown pulse lamp has a lamp tube 1, the two ends of the lamp tube 1 are electrodes 2, the lamp tube 1 is filled with a mixed gas containing deuterium and xenon, and the content of deuterium in the mixed gas is 0.02% to 0.02%. 0.12%. The electrode 2 is an anode supported by barium tungsten and a cathode made of barium tungsten impregnated with trace elements cesium and thorium.

[0015] Prefabricated steel cylinders are heated and evacuated to negative 4 Pa. Since the specific gravity of xenon and deuterium will cause stratification, it is mixed by heating at 80 degrees to 120 degrees, and the...

Abstract

The invention relates to the field of manufacturing of lamps, in particular to a pulsed lamp. The pulsed lamp is provided with a lamp tube. Both ends inside the lamp tube are provided with electrodes. Mixed gas of deuterium and xenon is filled in the lamp tube. The content of deuterium in the mixed gas ranges from 0.02 to 0.12 percent. The electrodes are an anode and a cathode which are prepared by permeating trace elements of caesium and thorium into barium tungsten. A spectral output range can be regulated. The deuterium is used in the tube and the caesium and thorium electrodes are used, and thus, the carrying capacity is improved in a lamp tube cavity, the lamp tube emits strong light in shorter time and part of spectrums of over 400 nanometers are transferred to spectrums of 100 nanometers to 285 nanometers so as to fulfill the aim of sterilization.

Description

technical field [0001] The invention relates to the field of lamp manufacturing, in particular to a pulse lamp, which shortens the light transmission time and prolongs the service life of the lamp tube. Background technique [0002] The pulse lamp is a kind of lamp with high luminous power and close to sunlight. The traditional pulsed lamps are all made of tube shape. The lamp tube is a fully transparent quartz tube with high temperature resistance and small thermal expansion coefficient. Two barium tungsten electrodes are sealed at both ends. The distance between the electrodes is generally greater than 100mm. The tube is filled with high-purity xenon gas. [0003] Since traditional pulse lamps mostly use high-purity xenon gas, it takes a long time for each pulse point to light the lamp, which affects the service life of the lamp tube. Moreover, because the electrodes mostly use barium tungsten, most of the spectra are above 400 nanometers, and the bactericidal effect is w...
