Specifically, the tube 1 is filled with an inert gas (generally, xenon gas), and the left and right ends of the tube 1 are a cathode end 11 and an anode end 12, respectively. In this embodiment, the tube 1 has a cylindrical cathode electrode and an anode electrode inside, so as to form the cathode end 11 and the anode end 12, the cathode electrode is made of materials such as tungsten barium, and is excited to generate electrons under the impact of a pulse high-voltage current, the anode electrode is made of materials such as tungsten, and the cathode is excited to generate electrons to move towards the anode under the impact of the pulse high-voltage current, and energy is released by flashing. In addition, the conducting rod of the cathode end 11 is wound with the getter sheet 13, which is mainly made of barium-aluminum and barium-titanium composite materials, and is melted into ingots in a vacuum furnace, then processed into powder, pressed into a metal disc or a ring to form a getter element, and the conducting rod arranged on the cathode end 11 is heated by high-frequency current to form a film, so that residual impurity gas in the inner lamp tube is absorbed through physical and chemical actions, the vacuum degree in the tube body 1 is maintained and improved, the tube body 1 has more stable performance, and the phenomenon that the lamp tube leaks or does not flash due to insufficient vacuum degree of the common xenon lamp tube in the market at present can not occur.
