In recent years, LED technology has continued to develop, and industry competition has intensified. Major manufacturers have begun to battle the niche market in search of a new blue ocean. UV LED, as a segment with high gross profit, has developed rapidly and has received high attention from the industry. Domestic and foreign manufacturers have invested in layout.
市场发展潜力巨大 UV LED has a wide range of applications and huge market development potential
What is UV LED? UV LEDs refer to LEDs with an emission wavelength of 400nm or less, which can be further divided into UVA (320-400nm), UVB (280-320nm), and UVC (200-280nm) according to the wavelength.
At present, the most widely used are UVA products, which are mainly used in industrial fields such as glue curing, PCB exposure, printing, and civilian fields such as mosquito trapping, nail art, anti-counterfeiting detection, and photocatalytic purification. UVB and UVC have higher thresholds, especially UVC. Among them, UVB is mainly used for phototherapy, and UVC is mainly used for sterilization.
According to the latest "Deep UV LED Application Market Report 2019-Sterilization, Purification and Water Treatment Market" released by LED Research Center of LED Consulting, under the influence of the global economic recession, the revenue targets of UV LED manufacturers in 2018 failed to meet the target. Explosive growth is expected, but still showing a steady increase. Looking forward to the application market demand, in addition to the stable growth of the curing market, surface / air sterilization and purification, stationary water sterilization, and flowing water sterilization will be the main growth momentum in the future. It is estimated that the output value of the UV LED market in 2023 will reach $ 991 million.
With the entry into force of the Minamata Convention, primary mercury mines will be completely banned around 2030, and the production and supply of primary mercury will not be possible in the future. Because UV LEDs do not contain mercury, they are environmentally friendly and safe, and they have the characteristics of fast start-up and high efficiency, and their market development potential is very huge in the future.
The application of UV LED in emerging fields is constantly expanding
With the continuous development of UV LED technology, the application of UV LED in some emerging fields has been continuously expanded.
“在光触媒领域，UV LED照射光触媒可使通过的空气中的有机污染源(甲醛、VOC)分解成无毒无污染的水和二氧化碳，使无机污染物(NOx , NH3)氧化成NO3-，进而实现杀菌消毒、分解空气污染物等功能。 ” Zhao Sen, general manager of Guoxing Optoelectronics' non-visual light source division, introduced: "In the field of photocatalysts, UV LEDs irradiated with photocatalysts can decompose organic pollution sources (formaldehyde, VOC) in the air into non-toxic and pollution-free water and carbon dioxide, making inorganic Pollutants (NOx, NH3) are oxidized to NO3-, which then achieves functions such as sterilization and decomposition of air pollutants. "
In addition, UV LEDs can be used for plant growth. In recent years, indoor and greenhouse planting has developed vigorously, which solves the problem of lack of fresh vegetables in cold regions in winter. However, some indoor and greenhouse vegetables and fruits on the market have darker colors and tastes. There are many reasons for this, but insufficient light, especially the lack of ultraviolet components in normal light, may be the key factor. Studies have found that supplementing certain doses of UV irradiation in greenhouses and other indoor plants can affect plant growth and physiological activities, thereby improving plant quality.
At the same time, the application of UV LEDs in the field of phototherapy has gradually become popular. UVB can effectively treat various skin diseases such as psoriasis and vitiligo. Compared with traditional NB UVB ultraviolet phototherapy devices and excimer laser treatment devices, UVB LED can do It has to be more compact, easy to carry and use, and the advantages are more prominent.
Today, with the continuous maturity of UV LED technology and the gradual decline of costs, UV LED will usher in new development opportunities.
Manufacturers actively deploy UV LED
In this regard, manufacturers at home and abroad are vying for layout, especially high threshold UVC LEDs, such as LG Innotek, Seoul Viosys, DOWA, Guoxing Optoelectronics, Qingdao Jiesheng, Hongli Bingyi, Everlight Electronics, etc. are actively developing UVC products. .
In the field of UV LED, Guoxing Optoelectronics has fully deployed UVA / UVB / UVC. Since 2016, it has successively launched near-UV LEDs, deep-UV LEDs and modules, with a wide range of products and high reliability.
Guoxing UV LED series products use high-reliability materials and excellent packaging technology. They have lower thermal resistance, higher light output, and better air tightness. Taking the silicone 3535 series as an example, the combination of nano packaging technology has greatly reduced the thermal resistance of the device. The thermal resistance is reduced by more than 40% compared with conventional packaging products. The device has better heat dissipation and longer life. At the same time, a more reasonable primary lens package is designed, and the optical power is increased by more than 6% than that of conventional products.
At present, Guoxing UV LED series devices have been widely used in sterilization, phototherapy, curing, photocatalyst, plant growth, mosquito trapping, nail art and other fields. The market feedback is good, and has established partnerships with many well-known manufacturers.
