Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
Embodiment
A kind of laser lamp electrode 1, its structure is as it is shown in figure 1, include: the barium tungsten receiving terminal 11 that cross section is gradually increased from front to back, is connected to the lanthanum tungsten body 12 at barium tungsten receiving terminal 11 rear, middle part is provided with the bulge loop of protrusion, and is connected to the tungsten connecting rod 13 of lanthanum tungsten body 12 rear end.Wherein, barium tungsten receiving terminal 11, lanthanum tungsten body 12 and tungsten connecting rod 13, in being coaxially disposed, weld together with Nickel Matrix Solder between barium tungsten receiving terminal 11 and lanthanum tungsten body 12.Being provided with draw-in groove in the rear end of lanthanum tungsten body 12, the front end of tungsten connecting rod 13 is embedded in draw-in groove.
This kind of laser lamp electrode 1 can be arranged in laser lamp, as shown in Figure 2, laser lamp includes glass tubing 2, using laser lamp electrode 1 as negative electrode, it is positioned at one end of glass tubing 2, the tungsten connecting rod 13 of laser lamp electrode 1 stretches out outside glass tubing, additionally includes the other end being arranged in glass tubing 2, the anode 2 being oppositely arranged with negative electrode.Filling xenon in glass tubing 2, pressure pressure in glass tubing 2 in 700-800Torr, the present embodiment is 760Torr.
The laser lamp using this kind of laser lamp electrode 1 is barium tungsten electrode sample lamp, and outer tactile firing voltage is on the low side, is conducive to improving the suitability of xenon lamp.Start more rapid.And clean-up performance is better than Ce-W electrode sample lamp after the test of barium tungsten electrode sample lamp, be conducive to improving the xenon lamp life-span.Under identical preionization current condition, the tube voltage drop of barium tungsten electrode sample lamp, significantly lower than Ce-W electrode sample lamp, is expected to improve the photoelectric properties of xenon lamp.
