Key Technologies
The technological maturity of different UV wavelengths shows a step-by-step development pattern, with significant differences in efficiency levels among UVA, UVB, and UVC technologies.
UVA (Near Ultraviolet)
UVA technology has entered a mature commercialization stage. Large-size 365nm UVA LED products can achieve optical power outputs exceeding 1000mW, with electro-optical conversion efficiency above 35%.
For 395nm UVA LEDs, efficiency has exceeded 40%, representing the advanced commercialization level of this wavelength range.
The key competition in the UVA market has shifted from “whether it can be manufactured” to cost optimization and reliability improvement.
UVB (Mid-Wavelength Ultraviolet)
UVB technology is currently in a rapid development and improvement stage.
For 308nm UVB LED products, mass-produced devices typically achieve optical power outputs of 15–35mW, with electro-optical conversion efficiency exceeding 5%.
Although UVB efficiency is still several times lower than UVA technology, its continuous improvement and commercialization progress are attracting increasing attention.
UVC (Deep Ultraviolet)
UVC LED technology is currently approaching a critical breakthrough stage.
Mass-produced UVC LED products in the industry have generally achieved electro-optical conversion efficiencies above 5%, while some advanced manufacturers have reached over 10% efficiency in mass production, with laboratory results exceeding 15%.
The UVC LED industry is transitioning from “usable technology” to “high-performance commercial solutions”, making it one of the key focus areas for current UV technology development.
