Making a simple comparison between UV LED and UVC LED is not the only way to decide which is superior. Depending on how you want to utilise them, each variety of LED has pros and cons of its own.
The term "UV LED" describes light-emitting diodes that operate in the ultraviolet (UV) portion of the electromagnetic spectrum. These are typically employed in sensing, curing, and disinfection applications. Their wavelength ranges from 100 to 400 nm. In contrast, diodes that emit ultraviolet-C light, which has a wavelength of 200–280 nm, are explicitly referred to as UVC LEDs. The main applications for UVC LEDs are sterilisation and disinfection.
The fact that UV LED technology has been around for a lot longer than UVC LED technology allows for greater study and development throughout time, which is one clear advantage of UV LED over UVC LED. As a result, UV LED technology is further developed and has more uses than merely sterilising and disinfection.
The field of curing is one such application. Inks, coatings, and adhesives can be polymerised by UV LED faster and more effectively than by conventional curing techniques, which frequently call for high temperatures. Because UV LED curing uses less energy to function, it is therefore more energy-efficient and environmentally friendly.
The fact that UV LED produces a wider spectrum of wavelengths than UVC LED is another significant benefit. Because of this, the range of applications it can be utilised for increases. UV LEDs are perfect for sensing applications since we can utilise them as UV-A, UV-B, and UV-C light sources. They can be used, for instance, to find out whether a sample contains specific chemicals, minerals, or other materials.
Nonetheless, UVC LED is a better option for sterilisation and disinfection applications due to a few significant benefits. To begin with, it has been demonstrated that UVC LED is very successful in eliminating pathogens such as bacteria, viruses, and mould. Studies have indicated that UVC LED is a very powerful disinfectant since it can reduce the efficacy of certain infections by up to 99.9%.
Being more energy-efficient than many other disinfection techniques, such chemical disinfection, is another fantastic benefit of UVC LED. Moreover, it generates no detrimental byproducts, contributing to its eco-friendliness even more. UVC LED has become an essential tool for disinfecting surfaces in hospitals, schools, and other public spaces due of the ongoing COVID-19 outbreak.
In conclusion, each UV LED and UVC LED have advantages and disadvantages, and the ideal option will rely on the particular use case you have in mind. UVC LED is very good at sterilising and cleaning surfaces with low energy consumption and no hazardous byproducts, even if UV LED's maturity and diversity make it a great option for a variety of applications. Whichever route you take, using the greatest technologies is necessary to get the results you want.
