Description

Technical Field

[0001] This utility model relates to the field of short-arc xenon lamp technology, specifically a short-arc xenon lamp with a quickly replaceable electrode. Background Technology

[0002] A short-arc xenon lamp is a high-brightness gas discharge light source that uses xenon gas as the discharge medium and adopts a short-arc discharge structure design. Its core features are short electrode spacing, concentrated arc light and high luminous efficiency. It is widely used in scenarios that require high-intensity, high-color-rendering light. Structurally, it is usually made of a transparent quartz glass shell, which encapsulates high-purity xenon gas inside. Both ends are equipped with high-temperature resistant tungsten electrodes, which are connected to an external power supply through metal leads. Some high-end models also have emission materials coated on the electrode surface to reduce the starting voltage and extend the service life.

[0003] Existing short-arc xenon lamps are widely used, but the electrode assembly in xenon lamps is usually fixedly connected to the glass cover. When the electrode is damaged, it cannot be replaced and the glass cover must be broken for recycling. Therefore, to address the above problem, a short-arc xenon lamp with a quick electrode replacement is proposed. Utility Model Content

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A short-arc xenon lamp with quick-change electrodes includes a glass cover 1, a cathode assembly 2 and an anode assembly 3 symmetrically mounted inside the glass cover 1. Glass rings 4, integrally formed with the glass cover 1, are symmetrically arranged at both ends of the glass cover 1. Mounting rings 5 ​​are fixedly connected to the sides of the cathode assembly 2 and the anode assembly 3 near the glass rings 4. Sealing rings 6 are provided on the side of the mounting rings 5 ​​near the glass rings 4, with their left and right sides tightly fitted to the mounting rings 5 ​​and the glass rings 4 respectively. A mounting assembly 7 is provided outside the mounting rings 5. The mounting assembly 7 includes a semi-open fixing ring 71 symmetrically arranged outside the mounting rings 5, the sealing rings 6, and the glass rings 4. Symmetrically arranged semi-cylindrical blocks 72 are fixedly connected to one side of the semi-open fixing rings 71. A positioning plate 73 is provided outside the semi-cylindrical blocks 72. A connecting threaded cylinder 74 is fixedly connected to one side of the positioning plate 73, and bolts 75 are threadedly connected to the inner side of the connecting threaded cylinder 74. The bolt 75 has a fixing plate 76 on its outer side, which is fixedly connected to the outer side of the cathode assembly 2 and the anode assembly 3 respectively. The semi-cylindrical blocks 72 on the two semi-open fixing rings 71 fit together, and the outer side of the semi-cylindrical blocks 72 fits together with the inner side of the positioning plate 73. Through the glass ring 4, mounting ring 5, sealing ring 6, mounting component 7, semi-open fixing ring 71, semi-cylindrical blocks 72, positioning plate 73, connecting threaded cylinder 74, bolt 75 and fixing plate 76, when the cathode assembly 2 and anode assembly 3 in the xenon lamp are damaged and need to be replaced, the bolt 75 can be unscrewed, and the connecting threaded cylinder 74 and the semi-open fixing ring 71 can be removed in sequence to repair and replace the cathode assembly 2 and anode assembly 3. This design allows the electrodes of the xenon lamp to be quickly installed and replaced, which is convenient for the maintenance of the xenon lamp. Moreover, it is not necessary to break the glass cover 1 when recycling the xenon lamp, making the maintenance of the xenon lamp more convenient.

[0025] Both the cathode assembly 2 and the anode assembly 3 are equipped with connecting pipes 8 that communicate with the glass cover 1. A threaded ring 9 is installed on the outside of the cathode assembly 2, and a threaded cap 10 is threadedly connected to the outside of the threaded ring 9. A one-way valve 11 is fixedly connected to the outside of the anode assembly 3. The threaded ring 9 and the one-way valve 11 are respectively connected to the connecting pipe 8. The gas supply direction of the one-way valve 11 is towards the connecting pipe 8. Through the connecting pipe 8, threaded ring 9, threaded cap 10 and one-way valve 11, when the cathode assembly 2 and the anode assembly 3 in the xenon lamp are damaged and need to be replaced, the threaded cap 10 can be unscrewed to allow the xenon gas to be discharged. This design simplifies the charging and discharging steps of the xenon lamp and makes it easy for users to install and disassemble the xenon lamp.

[0026] Workflow: When installing a xenon lamp, first insert both the cathode assembly 2 and the anode assembly 3 into the inside of the glass cover 1, and then place the semi-open fixing ring 71 on the outside of the mounting ring 5, the sealing ring 6, and the glass ring 4. Next, place the positioning plate 73 at one end of the threaded cylinder 74 on the outside of the semi-cylindrical block 72, so that the threaded cylinder 74 and the fixing plate 76 are horizontally aligned. Then, insert the bolt 75 into the fixing plate 76 and screw it into the inside of the threaded cylinder 74 until the sealing ring 6 is tightly fitted to the mounting ring 5 and the glass ring 4 on both sides. This completes the installation of the xenon lamp. Next, unscrew the threaded cylinder 74 from the outside of the threaded ring 9, and connect the one-way valve 11 to the xenon gas delivery system. Xenon gas can enter the inside of the glass cover 1 through the one-way valve 11 and the connecting pipe 8, and exit through the connecting pipe 8 and the threaded ring 9. Xenon gas is continuously supplied for a period of time. Afterwards, the air inside the glass cover 1 can be replaced. The next step is to screw the threaded cap 10 onto the outside of the threaded ring 9 and continue to introduce xenon gas until the pressure inside the glass cover 1 reaches the standard. The xenon lamp can then be used normally. When the cathode assembly 2 and anode assembly 3 in the xenon lamp are damaged and need to be replaced, the threaded cap 10 can be unscrewed to allow the xenon gas to escape. Then, the bolt 75 can be unscrewed, and the connecting threaded cylinder 74 and the half-open retaining ring 71 can be removed in sequence to repair and replace the cathode assembly 2 and anode assembly 3. The design of the mounting component 7 and its connecting components allows the electrodes of the xenon lamp to be quickly installed and replaced, which is convenient for the maintenance of the xenon lamp. Moreover, the glass cover 1 does not need to be broken when the xenon lamp is recycled, making the maintenance of the xenon lamp more convenient. The design of the threaded ring 9, the one-way valve 11 and its connecting components makes the charging and degassing steps of the xenon lamp simple, which is convenient for users to install and disassemble the xenon lamp.
