Problems solved by technology

Due to the difference in raw material formula and preparation process, most of the existing magnetic rings have performance problems such as wide temperature characteristics, Curie temperature, saturation magnetic induction temperature, etc.
[0003] In addition, the life of the energy-saving lamps prepared by the existing technology is relatively short, generally around 6000 hours
