UNDERSTANDING ULTRAVIOLET LED APPLICATIONS AND PRECAUTIONS

Bfvxn, Aschileu, Cluj, Romania Data publicari: Septembrie 9, 2021

UV LEDs have seen tremendous growth over the past several years. This is not only the result of technological advances in the manufacturing of solid state UV devices, but the ever increasing demand for environmentally friendly methods of producing UV light which is currently dominated by mercury lamps. The current offering of  UV LED modules in the optoelectronics market consists of product ranging from approximately 265nm – 420nm with a variety of package styles including through-hole, surface mount and COB (Chip-On-Board). There are many unique applications for UV LED emitters; however, each is greatly dependent on wavelength and output power. In general, UV light for LEDs can be broken down into 3 general areas. The middle UVA LED component area has seen the greatest growth over the past several years. The majority of applications in this wavelength range (approximately 350nm – 390nm) are for UV curing of both commercial and industrial materials such as adhesives, coatings and inks. LEDs offer significant advantages over traditional curing technologies such as mercury or fluorescent due to increased efficiency, lower cost of ownership and system miniaturization. The trend to utilizing LEDs for curing is increasing as the supply chain is continually pushing to adopt LED technology. Although the costs of this wavelength range is significantly greater than the upper UVA LED module area, rapid advances in manufacturing as well as increasing volumes are steadily driving down prices.The lower UVB LED and upper UVC ranges (approximately 250nm – 300nm) is an area that is still very much in its infancy, however, there is great enthusiasm and demand for this product in air and water purification systems. There are currently only a handful of companies that are capable of manufacturing UV LEDs in this wavelength range and even a smaller amount that are producing product with sufficient lifetime, reliability and performance characteristics. The introduction of the first commercial UVC LED based disinfection system in 2012 has helped to move the market forward to where many companies are now seriously pursing LED based products.
