In order to reduce the risk of tungsten wire fracture caused by thermal expansion and contraction, the following aspects can be considered and improved:
- Optimize tungsten wire material and design
Improve the purity of tungsten wire: Using high-purity tungsten wire material can reduce the impact of impurities on the performance of tungsten wire and improve its resistance to high temperature and thermal expansion and contraction.
Optimize tungsten wire structure: Designing tungsten wire into a spiral shape or other structure that is conducive to reducing thermal expansion and contraction stress can effectively reduce the stress concentration caused by temperature changes, thereby reducing the risk of fracture.
- Improve the manufacturing process
Precisely control the manufacturing process: During the manufacturing process of tungsten wire, strictly control the process parameters such as heating temperature and stretching speed to ensure that the internal structure and performance of tungsten wire reach the best state.
Adopt advanced welding technology: Using advanced technology such as electron beam welding to connect tungsten wire and electrode can reduce thermal stress and mechanical stress during welding and improve the reliability and service life of tungsten wire.
- Reasonably adjust working conditions
Stabilize voltage and current: Keep the voltage and current of the bulb stable when working to avoid excessive fluctuations that cause excessive thermal stress on the tungsten wire.
Limit the use time: Although the service life of halogen lamps is relatively long, long-term continuous use will still accelerate the evaporation and aging of tungsten wire. Therefore, if possible, limit the use time of the bulb, or use it intermittently to extend its life.
- Adopt protective measures
Fill with inert gas: Fill the bulb with inert gas (such as argon) to reduce the oxidation rate of tungsten wire at high temperature, thereby extending its service life.
Use anti-seismic bracket: Equip the bulb with an anti-seismic bracket to reduce the impact of external vibration or impact on the tungsten wire and reduce the risk of breakage.
- Comprehensive application of multiple technologies
Coating technology: Coating a protective film or anti-oxidation layer on the surface of the tungsten wire can further reduce the evaporation rate and oxidation rate of the tungsten wire at high temperature.
Temperature control technology: Using advanced temperature control technology, such as the intelligent dimming system, the brightness of the bulb can be adjusted according to actual needs, thereby reducing the working temperature of the tungsten wire and reducing the impact of thermal expansion and contraction.
