evolves. This growth is expected to continue in the next five years
and new potential applications will emerge.
The largest growth opportunities, however, will stem from new
applications such as the aforementioned UV-A integration into everyday items like smartphones/handheld devices for counterfeit detection or analysis. Likewise, UV-C integration into refrigerators for disinfection has huge potential. Still, these new applications are in the
very early stages of R&D, so it is difficult to forecast these markets.
Global market for UV LED applications
Now let’s consider the market potential. Fig. 3 projects the revenue
breakdown by type of UV LED: UV-A, UV-B, and UV-C. In general,
UV-A LEDs have higher penetration rates among all applications
because of lower prices. UV-A is a very good entry point for these
packaged LED manufacturers that produce white-light LEDs since
they can use their current MOCVD tools. It is forecasted that the
market for UV-A packaged LEDs will grow by approximately a 45%
compound annual growth rate (CAGR) over five years through 2020.
Fig. 4 projects the global potential for UV LED package by applications. As previously mentioned, the curing industry has had the
greatest usage and penetration of UV LEDs. That being said, other
applications are beginning to increase their usage of UV LEDs as the
technology evolves, with printing being the other main category in
the UV-A market. In general, a large printer needs a UV light engine
with approximately three to four rows of LEDs comprising hundreds
of 1W UV LED die.
Although water/air disinfection has a lower penetration rate
compared to other applications, we still forecast that the market has great potential and this is the main driver for UV-C LEDs.
From our research, we found the major market regions to be in
North America and Japan. Although the usage of UV LEDs is relatively limited in countries such as China and other emerging global
markets, it is expected that these regions are poised to undergo
