[0048] In order to make the content of the present invention clearer and easier to understand, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0049] figure 1 It shows the so-called one-sealing method used in the prior art to seal the HID arc tube. The exhaust process in this method is to use quartz glass to make a medium and high-power HID in the middle of the arc tube. Exhaust car exhaust on the exhaust pipe (practice has proved that this method destroys the geometric size of the discharge cavity, is not conducive to the metal halide cycle, affects the light output, life and light color stability), all are carried out by human hands, and It is also carried out in the glove box while wearing the gloves on the glove box, so it is difficult to ensure the pole distance and coaxiality of the two electrodes in the HID arc tube, so that the pass rate and consistency of the product cannot be guaranteed. In a...
