UVA LEDs still dominate due to UV curing boom

According to a report, Due to their compactness, lower cost of ownership and environmental friendly composition, UV LEDs are continuing to replace traditional UV lamps in incumbent applications, but will also create new applications.

In 2011, most UV LEDs sold were still in the near-UV (UV-A and UV-B) region of the spectrum . More than 90% of the UV LED market was still for industrial UV curing, counterfeit detection, and medical & instrumentation applications requiring UV-A/B sources. In particular, UV-A is currently dominant and will remain so for at least the next 5 years.

The key applications for UV-A are UV curing, counterfeit detection and photocatalyst air purification. Among these, the most dynamic and important market is UV curing, where UV LEDs compete with traditional mercury lamps, offering advantages in terms of cost of ownership and system miniaturization. Also, recent improvements in 2011 have greatly increased the power output available at the window surface of UV LEDs to 16W/cm², which should lead to cheaper lamps. So far in 2012 two professional associations dedicated to UV LED curing have been formed, showing the robustness and credibility of UV LED technology.
