Behind The Scenes: Manufacturing Process of a Far-Uvc 222nm Excimer Lamp

1. Raw Material Selection :Quartz Sand –
   

   Raw Material: Quartz Sand – The process begins with sourcing high-purity quartz sand (SiO₂ > 99.9%) , which serves as the base material for producing quartz tubes. The purity of quartz is crucial as it directly impacts the performance (UV Intensity) and longevity of the lamp

2. Quartz Tube Formation
   

   The quartz sand undergoes a melting process at high temperatures to form quartz tubes. These tubes are then drawn and shaped into the desired size according to the lamp specifications. The consistency of the tube’s thickness and quality is monitored to ensure uniformity.

3. Cutting and Shaping the Quartz Tube
   

   Once the quartz tubes are formed, they are cut to the required length and shaped accordingly. This step ensures that the tube dimensions match the specifications needed for optimal performance. Critical dimensions (length, diameter, wall thickness) are tailored for optimal UV output.

4. Gas Preparation for 222nm Emission

   A critical step in the manufacturing process is preparing the correct gas mixture that enables the lamp to emit 222nm ultraviolet light. The gas mixture typically includes noble gases like krypton and chlorine, which are carefully measured and purified before use.Excimer formation requires a noble gas and halogen mixture : For 222nm: – **Krypton Chloride (KrCl) A blend of krypton (Kr) and trace chlorine (Cl₂) gas

5. Gas Filling Process

   The prepared gas mixture is injected into the quartz tube using a specialized vacuum-sealing process. Maintaining the right pressure and composition of the gas is crucial for achieving the correct wavelength and efficiency of the lamp.**Preparation：Cleaning-The quartz tube is ultrasonically cleaned to remove contaminants.  Evacuation-A vacuum pump removes air/moisture

    

6. Assembly of the Lamp Components
   

   Electrodes and Internal Components – Electrodes, both internal and external, are installed to facilitate the electrical discharge necessary for producing the 222nm wavelength. The placement of these components must be exact to ensure stable operation and longevity of the lamp.
   Ceramic End Caps – High-temperature-resistant ceramic caps are glued to tube ends using UV-stable epoxy

7. Final Testing and Quality Assurance
   

   The assembled excimer lamp is connected to a ballast for testing. Each lamp undergoes rigorous testing to ensure it meets the required UV intensity and performance standards. Parameters such as wavelength accuracy, power consumption, and durability are carefully evaluated before the lamp is approved for distribution.
   **Process: Ignition Test/UV Intensity Measurement/Ballast Compatibility/Visual Inspection/Dimensional Check etc.
