In recent years, the competition in the LED lighting market has intensified and the profit margin has been continuously compressed. In order to seek new profit growth points, many LED manufacturers began to explore the high-margin application market, actively deploying more potential LED niche markets such as automotive lighting, infrared (IR) and ultraviolet (UV).
At present, UV LEDs are gradually replacing traditional ultraviolet light sources. The French consulting company Yole development data shows that the market size of UV LEDs will reach 150 million US dollars in 2016, and the market share in the traditional UV market will increase from 10.4% in 2011 to 2016. 28.1%.
UV LED applications are favored
UV LED is an LED that emits ultraviolet light of different wavelengths from 200nm to 400nm. It can be used in various fields such as sterilization, air purification, medical treatment, gas detection, food manufacturing, and beauty according to different wavelength ranges. Compared with traditional mercury lamps, UV LEDs have the characteristics of energy saving, less heat loss, long life, and concentrated curing wavelengths. Therefore, they are favored by the market and are becoming a new blue ocean in the LED field.

Depending on the wavelength of the luminescence, the field of UV LED applications varies. UV-A field (315~400nm) is mainly used in industrial curing equipment, money detectors, etc.; UV-B field (280~315nm) is mainly used in therapeutic/analytical instruments, vitamin D synthesis, etc. in medical/biological fields. The UV-C field (280~200nm) is mainly used in environmental fields such as sterilization/purification/clean water.

Green Viophoton technology
Currently, UV LED solution provider Seoul Viosys has launched Viophoton technology. Mainly used in the field of UV-C. This technology is the first of its kind in the world.
It is understood that Viophoton technology is based on the photocatalytic reaction of titanium dioxide with ultraviolet light to produce a free hydroxyl radical and active oxygen with strong oxidizing ability, and has a strong photooxidation and reduction function. Oxidative decomposition of various organic compounds and some inorganic substances, can destroy bacterial cell membranes and solidify viral proteins, thereby killing bacteria and decomposing organic pollutants (VOC), decomposing organic pollutants into non-polluting water (H2O) and Carbon dioxide (CO2).
Simply put, Viophoton technology has strong sterilization, deodorization, mildew proof, anti-fouling and self-cleaning functions. Through the adsorption and catalysis of harmful substances, the harmful gases such as formaldehyde and ammonia released from interior decoration materials and furniture are purified. “It is green and environmentally friendly, and it is very suitable for environmentally friendly products,†said the relevant person in charge of Shijian Company, a Viosys agent in Seoul.

The application of Viophoton technology is closely related to people's lives. Air quality is directly related to human health, especially in such severe weather conditions as haze, and the consumer demand for air purifiers is also increasing. The test data shows that the air purifier with Viophoton technology can improve the purification function of the ordinary purifier by 10 times, can effectively remove harmful gases and odors, and strengthen antibacterial and killing. .jpg)
