As editor Maury Wright explains in a feature covering LED and solid-state lighting innovations and updates presented at Strategies in Light 2014, ultraviolet LEDs are able to be leveraged due to the properties they exhibit in various spectra. UV-A LEDs (315–400 nm) are commonly used in curing applications, while UV-B and UV-C LEDs (280–315 nm and 100–280 nm, respectively) have potential in medical applications and purification/disinfection processes. Advances in these devices will depend on materials R&D evolving as well as manufacturing processes.
