In 2017, the UV LED market and applications will show a rapid development trend.
As you can see, more and more companies at home and abroad are rushing into this segment. From the perspective of global market size, the UV LED in 2017 will reach 280 million US dollars, which is expected to exceed 1/3 of the entire UV light source market. In 2020, it will see 526 million US dollars, and the composite growth rate (CAGR) 2015-2020 Up to 34%.
The rapid development of the market, from the policy point of view, the promotion of the Minamata Convention, energy-saving concessions, etc. contributed to the work. From the technical development point of view, it is predicted that the external quantum efficiency of deep ultraviolet LED will increase to about 15% in 2017, and the output power will exceed 30mW at room temperature, which will accelerate the penetration of ultraviolet LED in the field of sterilization, disinfection and purification.
At the same time, due to the increasing diversification of invisible LED applications, the LED industry has also seen new business opportunities. Among them, UV LED products continue to be introduced into various applications such as curing, printing and exposure.
It has been observed that UV LEDs are mainly used in the photocuring market for UV-A LEDs. Among them, the market for exposure machines with high illuminance and high uniformity is the most sought after. In addition, some special curing market demand is also emerging.
Internationally, in terms of UV LED package revenue, Japanese and Korean manufacturers are firmly in the top five, followed by Nichia, Nitride Semiconductors, Seoul Viosys, LG Innotek and USHIO/Epitex. Looking back on 2016, the main revenue of UV LED manufacturers is still from UV-A LEDs, and some manufacturers have already stepped into the light curing module market to further expand their revenue sources.
Looking ahead to the performance of the manufacturers in 2017, Korean manufacturers will release a series of UV-C LED products, which are expected to contribute significantly to revenue, and the revenue ranking is expected to be reshuffled.
In China, with the rapid improvement of semiconductor lighting technology, the gap between domestic and international advanced levels is further narrowing. The data shows that the deep ultraviolet LED technology is further improved. The continuous output power of 280nm deep ultraviolet LED at room temperature exceeds 20 mW, which is at the advanced level in the world.
In mid-June this year, the 2017 Taipei International Photonics Week in Taiwan, China, UV LED application has also become a highlight. It is reported that the Taiwan factory is also actively deploying UV LEDs in view of the red sea situation of LED blue light.
