This study explores how to optimize the performance of UV-C LED water disinfection modules by examining key factors such as heat dissipation materials, driving current, and optical design. Findings show that copper substrates significantly lower light power attenuation (41.90% vs. 53.94% with aluminum), extending LED lifespan. Increasing the driving current from 100 mA to 200 mA improves E. coli inactivation to >99.999%, meeting drinking water standards. An optimized optical structure—reducing LED beads from six to four and adding individual perforations—maintains high sterilization rates while cutting costs by 33%. These insights support the development of efficient, durable, and cost-effective UV-C LED disinfection systems.
The study demonstrates that the MASSPHOTON Q6060-D UV-C air sterilizer, utilizing 260–280nm UVC LED technology, effectively achieves multi-functional air purification. It inactivates airborne bacteria and viruses, removes TVOCs, PM2.5, and ammonia, with sterilization rates over 70% in real-world spaces and up to 99.9% odor removal in testing. This highlights its strong potential for commercial indoor air disinfection and odor control.
