specific Embodiment approach
[0013] figure 1 It shows that a specific embodiment of the present invention is: a high-brightness electrode for an ultra-high pressure mercury lamp, comprising a rod-shaped tungsten electrode (1) and a coil (2) on the discharge end side of the rod-shaped tungsten electrode (1) The discharge end of the electrode (1) is a cone-shaped electrode tip (11), and the electrode tip (11) is formed by welding the discharge end with tungsten solder by means of argon arc welding.
[0014] figure 2 Shown, during use, two electrodes 1 of the present invention are relatively fixed on both sides of the arc tube 3 by using the prior art, so that the pole tips of the two electrodes are opposite, and mercury, Argon and tungsten circulating gases are sufficient.
