The light decay problem of tungsten wire can be improved by the following methods:
1.Optimize tungsten wire materials and manufacturing processes
Improve the purity of tungsten wire:
By increasing the purity of tungsten wire and reducing the impurity content, the light decay caused by impurities can be reduced. High-purity tungsten wire has better thermal stability and anti-evaporation performance, thereby extending the service life.
Improve the manufacturing process:
Using advanced manufacturing processes such as electron beam evaporation and sputtering deposition, a tungsten wire film with a denser and more uniform structure can be prepared. This helps to reduce the light decay caused by manufacturing process defects.
- Improve the working environment and conditions Reduce the working temperature: The light decay of tungsten wire is closely related to the working temperature. By reducing the working temperature, the evaporation and sublimation of tungsten wire can be reduced, thereby reducing the light decay rate. Heat dissipation devices, cooling systems and other measures can be used to reduce the operating temperature of tungsten wires.
Optimize the gas environment:
Filling the tungsten wire with appropriate gas, such as inert gas, can slow down the oxidation and evaporation rate of the tungsten wire.
At the same time, the pressure and composition of the gas also need to be optimized to achieve the best light decay control effect.
- Use advanced packaging technology
Choice of packaging materials:
Choosing packaging materials with high thermal conductivity, low permeability and good chemical stability can effectively protect the tungsten wire from the external environment.
These materials can reduce the interaction between the tungsten wire and the packaging material, thereby reducing light decay.
Design of packaging structure:
Adopting a reasonable packaging structure design, such as adding heat dissipation fins, optimizing air flow channels, etc., can improve the heat dissipation performance of the package.
This helps to reduce the operating temperature of the tungsten wire, thereby slowing down the light decay rate.
- Strengthen maintenance and care
Regular inspection and replacement:
Regularly inspect the tungsten wire in use to promptly detect and replace aging or damaged tungsten wires.
This can avoid light decay problems caused by aging of tungsten wires.
Cleaning and maintenance: Keep the tungsten wire and its surroundings clean to avoid dust, oil and other pollutants. Regularly clean the pollutants on the surface of the tungsten wire to extend its service life and reduce the light decay rate.
- Use anti-light decay technology
Surface treatment technology: Special treatment of the surface of the tungsten wire, such as coating, can form a protective layer to slow down the evaporation and oxidation rate of the tungsten wire.
These protective layers can also improve the corrosion resistance and thermal stability of the tungsten wire.
Doping technology: By doping the tungsten wire with an appropriate amount of other elements, its microstructure and performance can be changed.
Doping elements can improve the anti-evaporation performance and thermal stability of the tungsten wire, thereby reducing the light decay rate.
