Recent improvements in UV-LED flux density, stability and life hours have made
UV-LEDs a viable solution for replacing traditional UV light sources such as
mercury arc lamps, arch lamps, hot and cold cathode lamps and grid lamps.
UV LEDs are more environmentally friendly as they do not contain harmful
mercury,do not produce ozone and consume less energy.
Use of UV LEDS is now rapidly growing in applications such as air, surface and
water sterilization (germicidal - UVGI), digital printing, pesticide detection,
phototherapy, as a UVA/UVB source for plant growth, nail art and polish curing,
UV curing of environmentally friendly curing formulations, counterfeit detection,
black lights, bio-analysis, medical, sensing etc.
