This blog post delves into the key takeaways from TrendForce’s insightful market research report, “2024 Deep UV LED Market Trend and Product Analysis- Technological Innovations to Drive Expanded Applications.” We’ll explore the projected growth of the UV LED market, analyze the latest advancements in UV LED technology, and unpack the expanding applications of this exciting light-emitting diode (LED) technology, particularly within the realm of ultraviolet germicidal irradiation (UVGI).
Market Growth Fueled by Innovation
The TrendForce report paints an optimistic picture for the UV LED market, anticipating a value of USD 309 million by 2028. This significant growth is attributed to continuous advancements in UV LED technology and its expanding application in various sectors, including curing (inkjet printing, 3D printing), medical applications (phototherapy), disinfection/purification (air and water treatment), air purification (photocatalysis), tanning, horticultural lighting, and even food preservation.
Key Players and Market Trends
Seoul Viosys has consistently held the top position in terms of UV LED revenue since 2019. Notably, ams OSRAM has made significant strides in the Asia Pacific (APAC) UV-C LED market, securing a spot among the top ten revenue generators for the first time. While most manufacturers remain cautious about market performance in 2024, they anticipate achieving a revenue growth of 5-10%.
Here’s a closer look at some of the key market trends highlighted in the report:
- UV Curing: The consumer market is expected to rebound in the second quarter of 2024 (2Q24), driving demand for UV curing applications in areas like inkjet and offset printing, 3D printing, and resin/adhesive curing. In the long run, advancements in UV-B and C LED technologies could potentially disrupt the UV curing market by mitigating the effects of oxygen inhibition.
- Photocatalytic Air Purification: Combining UV-A LEDs with photocatalytic technology offers a powerful solution for air purification and long-term bacterial elimination. This technology is already being implemented in home appliances like refrigerators, air conditioners, wardrobes, and lighting fixtures.
- Tanning, Horticultural Lighting, and Food Preservation: Nichia, Seoul Viosys, Violumas, and UVT are among the leading companies actively promoting UV-A and B LEDs in this market. Notably, the introduction of UV-B LED products is expected to further stimulate market growth.
- Medical Applications: Due to their compact size, UV LEDs are ideal for portable phototherapy devices. With the growing maturity of 308/310nm UV-B LED technology, medical device manufacturers are increasingly adopting UV-B LEDs and pursuing relevant healthcare certifications. While the certification process can be rigorous and time-consuming, collaboration between medical device and UV LED makers suggests promising potential for this market in the coming years.
- Disinfection and Purification: Manufacturers are continuously developing high-power single-chip UV-C LED products (≥80mW) and UV-C COB LED integrated packages. These advancements are expected to drive adoption in home appliances and flowing water disinfection applications between the second half of 2024 and 2026. Interestingly, the Huawei-affiliated electric vehicle (EV) brand AITO has adopted UV-C LED air disinfection technology, potentially paving the way for similar solutions in other car manufacturers. Compared to traditional UV lamps, UV LEDs offer a longer lifespan and a simpler optical design. When wall-plug efficiency (WPE) reaches ≥10% and prices approach USD 0.1/mW, UV LEDs are expected to find application in industrial water treatment. Finally, as the optical power and product lifetime of UV-C LEDs improve to meet industrial and commercial requirements, their adoption in flowing water disinfection systems is anticipated between 2026 and 2027.
The report also highlights the growing availability of high-power UV-C LED products (≥100mW) from leading manufacturers like Nichia, ams OSRAM, NKFG, LITEON, and UVT. These advancements offer not only desirable optical power but also maintain product reliability with a lifespan of 10,000 hours (R70).
Conclusion: A Bright Future Illuminated by Deep UV LEDs
The TrendForce report underscores the immense potential of Deep UV LEDs, extending far beyond traditional germicidal irradiation (UVCGI). With continuous advancements and expanding applications, UV LEDs are poised to revolutionize various industries, from healthcare and food preservation to air purification and industrial processes. As the technology matures and costs become more competitive, we can expect even wider adoption of Deep UV LEDs, illuminating a brighter future for disinfection, environmental sustainability, and human health.
