Tube Formation : The raw materials are converted into tubes or ampoules that will be used in the UV lamp. This process may involve shaping, heating and cooling glass or quartz to create the desired shape and size.
Electrode deposition : Electrodes, usually made of metal alloys such as tungsten or kovar, are deposited on the inside wall of the tube. The electrodes are used to conduct electrical current through the gas inside the tube.
Gas filling : The tube is filled with a special gas or gas mixture that plays a key role in the process of generating ultraviolet radiation when exposed to an electric discharge.
Sealing and Evacuation : After filling the tube with gas, it is hermetically sealed or sealed, and then subjected to vacuum to remove air and moisture from the inside to prevent oxidation of the electrodes and maintain the stability of the lamp.
Testing and Quality Control : After all stages of UV lamp production are completed, rigorous testing will be carried out, including checking the tightness, irradiance, electrical performance and other parameters, to ensure that the quality standards are met.
Packaging and Shipping : The final UV lamps are packaged and prepared for delivery to the customer or distributor who then distributes them to the market.
These UV lamp manufacturing technology basics provide a simplified overview of the process, which may vary depending on the specific specifications, standards and technologies used by the manufacturer.

Stages of the production process
The manufacturing process of ultraviolet (UV) lamps typically involves several stages, each of which plays an important role in creating a quality product. Here are the main stages of the UV lamp manufacturing process:
Preparation of raw materials and supplies :
This stage involves purchasing and preparing the necessary materials such as glass, quartz, electrode metals, gases and other components.
Formation of the lamp body :
This step transforms the materials into tubes or ampoules that will serve as housing for the UV lamp. This may involve shaping, heating and cooling glass or quartz.
Application of electrodes :
Electrodes, usually made of metal alloys, are sprayed onto the inside wall of the UV lamp tube. The electrodes are needed to conduct electrical current through the gas inside the lamp.
Gas filling and sealing :
UV lamp tubes are filled with a special gas or gas mixture and then hermetically sealed or sealed. This process provides the necessary conditions for the generation of ultraviolet radiation when the lamp is operating.
Testing and quality control :
UV lamps are thoroughly tested to ensure they meet quality requirements and specifications such as radiant intensity, electrical parameters, stability and durability. This includes lifespan tests, leak tests and other tests.
Packaging and delivery :
The final UV lamps are packaged and prepared for delivery to the customer or distributor. This step includes packaging in protective materials and labeling for product identification.
Each of these steps plays an important role in creating high-quality UV lamps, ensuring their reliable operation and compliance with quality standards.
Preparation and processing of materials
Preparation and processing of materials are important stages in the production of ultraviolet (UV) lamps, since the efficiency and reliability of the final product depend on the quality and condition of the materials used. Here are the main steps in preparation and processing of materials:
Purchasing raw materials : The first step is to purchase the necessary materials for the production of UV lamps. This includes glass, quartz, metals for the electrodes, gases and other components.
Material Manufacturing : In some cases, additional processing of raw materials is required. For example, glass or quartz may require shaping, cutting, or machining to achieve the desired dimensions and shapes.
Electrode Processing : Metal materials used for electrodes can undergo various processing processes such as casting, molding, coating and CNC machining to create the desired shape and size.
Material Quality Control : Before use, materials undergo quality control, which may include dimensional checking, visual inspection for defects, compositional analysis and other tests.
Warehousing and Storage : After preparation, materials are stored and stocked in a safe and damage-preventive manner until they are used in the production process.
Feeding Materials to Production Lines : Prepared materials are fed to production lines where they are used to create components and assemble UV lamps.
Proper preparation and processing of materials plays a key role in ensuring high quality and reliability of UV lamps, as well as in minimizing waste and increasing production efficiency.
Assembly and testing of finished products
After the components and materials are prepared, the ultraviolet (UV) lamp assembly stage takes place, which includes several steps. After assembly, testing is carried out to ensure the quality and functionality of each product. Here is a general overview of the stages of assembly and testing of finished UV lamps:
Assembly of components :
At this stage, the various components such as tubes, electrodes and other parts are assembled together into a single unit. This may include securing the electrodes inside the tube, connecting the various parts and installing additional elements such as glass bulbs or protective covers.
Connecting electrical components :
The electrodes and conductors are connected to an electrical circuit, allowing electric current to flow and creating a discharge inside the lamp.
Sealing and hermetization :
After assembly, the UV lamp is hermetically sealed or sealed to prevent gas and moisture leaks, which may reduce the efficiency and longevity of the lamp.
Testing before shipping :
Once assembled and sealed, each UV lamp is tested to ensure it is functional and meets quality requirements. This may include testing electrical performance, UV output, thermal performance, and more.
Correction and adjustment :
If it is necessary to detect any faults or deviations from the specified characteristics, the UV lamp is adjusted and regulated.
Packaging and labeling :
Once testing has been successfully completed, the finished UV lamps are packaged in protective packaging materials and labeled for identification and to ensure safe delivery to the consumer.
These stages not only ensure high-quality production of ultraviolet lamps, but also guarantee their compliance with safety standards and requirements.
