The following aspects can be used to reduce the tungsten wire startup loss through power supply design:
- Optimize the power supply output characteristics
Provide a stable startup voltage:
Ensure that the power supply can provide a stable voltage output at startup to avoid excessive voltage fluctuations that cause excessive instantaneous current in the tungsten wire, thereby generating additional startup losses.
Reasonable startup current limit:
When designing a power supply, a reasonable startup current limit should be set. By limiting the size of the startup current, the thermal shock and mechanical stress of the tungsten wire during the startup process can be reduced, thereby reducing startup losses.
- Use soft start technology
Soft start circuit:
Add a soft start circuit to the power supply design so that the power supply can gradually increase the output voltage and current at startup to avoid instantaneous high voltage and high current from impacting the tungsten wire.
Slowly increase power:
Through soft start technology, the power supply can slowly increase the output power during the startup phase, so that the tungsten wire gradually heats up to a stable working state, reducing the loss during the startup process.
- Improve power supply efficiency and response speed
High-efficiency power supply design:
Optimize power supply design and improve power supply efficiency. High-efficiency power supply can reduce energy loss, thereby reducing the power consumption of tungsten wire when starting.
Quick response capability:
The power supply should have a fast load response capability so that the output voltage and current can be adjusted in time when the load changes, so as to maintain the stable operation of the tungsten wire and reduce the loss during startup and stable operation.
- Choose the right tungsten wire and bulb design
High-quality tungsten wire:
Choose high-quality tungsten wire material to ensure that the tungsten wire has good heat resistance and oxidation resistance, thereby reducing startup loss.
Optimize bulb design:
Optimize the internal structure and gas composition of the bulb to improve the heat dissipation performance and luminous efficiency of the bulb. Good heat dissipation performance helps to reduce the operating temperature of the tungsten wire and reduce startup loss.
- Strengthen maintenance and regular inspection
Regular inspection and maintenance:
Regularly inspect and maintain the power supply and bulb to ensure that the power output is stable and the inside of the bulb is clean and free of impurities to reduce startup loss.
Replace aging parts in time:
Aged or damaged power supply components and bulbs should be replaced in time to ensure the normal operation of the power supply and bulb and reduce startup loss.
