UV LEDs should represent ~28% of the total UV lamp market (M$) by 2016

Thanks to its compactness, lower cost of ownership and environmental friendly composition, UV LEDs continue replacing traditional UV lamps in incumbent applications, but will also create new applications, especially portable ones.
Hence, UV LED business is expected to grow from $32.5M in 2011 to more than $150M in 2016: within this period, UV LED market (M$) will grow by a factor x5 whereas the traditional UV lamps market will only grow by a factor x1.5 (Figure 1).
In 2011, LEDs keep on being sold mostly in the UVA/B spectrum (especially in upper wavelengths, between 365 to 400 nm). More than 90% of the UV LED market (outside of R&D) was still covered by UV curing, counterfeit detection and medical & instrumentation applications requiring UVA/B sources. Concerning UVC LEDs, they were still mainly sold for R&D and scientific instrumentation purpose, but 2012 should see the commercialization of the first UV LED based purification system.
UVA (400-315nm) business is currently the main UV LED market and will remain so for at least the next 5 years:
90 % of the market (M$) in 2010
85 % of the market (M$) in 2016
The report details market metrics of traditional UV lamps and UV LEDs market within the period 2011-2016, presenting: the split by application for each technology (volume & market size), the penetration rate of UV LEDs…

UV LEDs are totally changing the value & supply chains

The booming UV LED market has attracted several new players from different backgrounds over the past years: traditional mercury lamp supplier, traditional UV curing systems suppliers, pure UV LED curing system suppliers, visible LED suppliers, substrate suppliers… Each player addressing different strategy to capture the maximum of value created by this disruptive technology (Figure 2).
At the device level, Asian companies, especially Japanese and Taiwanese ones, have taken the lead on the UV LED market but recently, some Chinese companies have also entered the playground: this should increase competition, reduce prices and enable mass applications at middle/long term.
Beyond that, as for visible LEDs few years ago, the value chain is consolidating with the arrival of pure players at the packaging and system level mainly, allowing:

To increase performance of UV LEDs with specific package developments.
To easier technological transition with traditional UV system manufacturers.
The report shows the UV LED industry: the main players & associated strategies/ business models, the industrial value & supply chains in 2011 for UVA/B and UVC, the revenues and market shares of key players…

UVA LEDs still dominate thanks to UV curing business boom

Key applications for UVA are UV curing, counterfeit detection and photocatalyst air purifier. Among those, the most dynamic and important market is clearly the UV curing business where UV LEDs definitely compete with traditional mercury lamps and offer significant advantages in terms of cost of ownership, system miniaturization (…):
2 professional associations dedicated to UV LED curing have been formed in 2012, showing the robustness and the credibility of the UV LED technology.
Recent improvements have greatly increased the power output available at window surface of UV LEDs to 16W/cm² in 2011.
The report details all UVA applications (with a deep analysis of UV curing), presenting: UV working principle, market structure, UV LEDs market drivers/challenges and characteristics required, Total Accessible Market (TAM) for UV LEDs…

UVC LEDs are still in development but commercialization should be earlier than expected

Water & Air purification are the potential next high volume applications for UVC LEDs. And in 2011, the UVC LED industry achieved a new milestone of structuration:
Crystal IS has been acquired by Asahi Kasei (large Japanese group).
Dot Metrics, the first pure UV LED water purification company, announced they (in partnership with Aquionics) will launch a first commercial product in 2012.
SETi announced the increase of its production capacity by a factor x6 with $20M investment.
In parallel, numerous research results published in 2011 have demonstrated an impressive improvement of the optical power output of UV LEDs: up to x10 compared to 2010. Hence, we expect that UVC LEDs should penetrate those key applications in 2014 after having completely solved the efficiency, lifetime and cost challenges.
Growth of the UVC market will also be connected to the availability of bulk AlN substrates that could improve the performance of the devices.
The report details all UVC applications (with a deep analysis of purification), presenting: UV working principle, market structure, UV LEDs market drivers/challenges and characteristics required, time to market & Total Accessible Market (TAM) for UV LEDs…

More than 50% performance improvement for bulk AlN based UV LEDs in 2011

Templates (AlN on Sapphire) are definitively the substrate of choice for UVA/B applications due to their lower cost and sufficient performance.
But for UVC applications, the competition with bulk AlN is increasing as such substrate could offer improvement of lifetime and power output of the UV LEDs: for example, in 2011, Crystal IS has improved its bulk AlN based UV LED results by a factor x20.
Several players are also targeting to commercialize 2” bulk AlN wafers by the end 2012. Therefore, the time to market for UVC applications based on bulk AlN would probably be in 2013-2015. However, as no research have clearly demonstrated the effect of bulk AlN substrate on UV LEDs performance, future commercial success of such substrate for UVC purification applications is still under debate.
The report details UV LED roadmap, presenting: performance and price roadmap, main specifications to enable UVC applications… Substrate industry is also analyzed: competition AlN template vs. bulk AlN, key companies…
