Abstract
The utility model discloses a high-strength gas discharge electrode, wherein the electrode comprises a master rod and a discharge end which is formed with, at one end of the master rod, a discharge part after the instant high-temperature fusion treatment; the diameter of the discharge part is larger than or equal to the diameter of the master rod; the metallographic structure of the discharge part is compact, the surface area of the discharge part is increased effectively and the gas is energized quickly, so as to stabilize the occurrence point of an electric arc at the discharge part and extremely relieve the sputtering of the discharge end of the discharge electrode during the lighting process of high-strength gas-discharge source, therefore, the service life and the light maintaining rate of the high-strength gas-discharge source can be improved, the high-strength gas-discharge source can be started promptly, the electric arc has good stability, the light focusing is strong, and no flicker is caused.
Description
Technical field
The utility model relates to the gas discharge electrode field, is specifically related to high strength gas discharge electrode.
Background technology
A kind of high strength gas discharge electrode, comprise high intensity discharge lamp electrodes such as high-pressure mercury lamp, high-pressure sodium lamp, quartz metal halide lamp, ceramic metal helide lamp, high pressure xenon lamp, automobile quartz metal halide headlight, ultrahigh pressure mercury lamp, no mercury lamp, also comprise the emission electrode that the starting the arc emission electrode of LASER Light Source and the various metal materials that military light source is used are made.Mainly determine in the light sustainment rate and the useful life of high-pressure discharge light source by sparking electrode, existing high strength gas discharge electrode mainly is to form discharge end at mobile jib one end through the electrode of prior powder metallurgy processes, the electrode metallurgical structure that powder metallurgical technique is produced is loose, and the electrode discharge end easily produces sputter and causes light source life to reduce and the light decay increase in high intensity discharge light source burning-point process.Still there is not at present the discharge position that a kind of high strength gas discharge electrode can form the metallurgical structure densification, reach the effect that alleviates the discharge end parts sputter in the burning-point process of high intensity discharge light source, thereby promote the life-span and the light sustainment rate of high intensity discharge light source.
Summary of the invention
Goal of the invention of the present utility model provides a kind of high strength gas discharge electrode that is formed with the discharge position of metallurgical structure densification.
Goal of the invention of the present utility model can realize by following technical scheme:
A kind of high strength gas discharge electrode comprises mobile jib and the discharge end that is formed at this mobile jib one end, it is characterized in that: the discharge end that is formed with the discharge position of process TRANSIENT HIGH TEMPERATURE melt process at an end of described mobile jib.
Can preferably described discharge part bit length be 0.01-5mm.
Can be greater than or equal to the mobile jib diameter by preferably described discharge position diameter.
Can be made as spheroid, spherocylinder and cone by preferably described discharge end.
Can also be set as winding screw body on described mobile jib by preferably described discharge end, fusion is the discharge position of one through TRANSIENT HIGH TEMPERATURE to form described mobile jib and described helicoid at described discharge end.
Beneficial effect of the present invention:
The utility model is formed with the discharge end at the discharge position of process TRANSIENT HIGH TEMPERATURE melt process at an end of described high strength gas discharge electrode, this position metallurgical structure densification of discharging, can alleviate the sputter of high intensity discharge light source discharge end parts in the burning-point process dramatically, thereby promote the life-span and the light sustainment rate of high intensity discharge light source, through the burning-point life test, the life-span of high intensity discharge light source prolongs more than 50%, 2000h light sustainment rate is promoted to more than 80%.And the diameter at described discharge position is greater than the diameter of electrode mobile jib, effectively increased the surface area at discharge position, when described high intensity discharge light source starts, energy is excited gas fast, and the origination point that can make electric arc is stabilized in the discharge position, thereby makes that high intensity discharge light source starter is rapid, arc stability good, light is poly-by force, do not glimmer.
