In order to gain an in-depth understanding of the technology and market trends of the UV LED market in recent years, research institutions have collected statistics on the UVC-LED development trends in the industry to make a summary and analysis for reference by industry professionals.

Enterprise layout: from capital chase to strong joint power terminal

In recent years, with the improvement of product power and technological refinement, UV LED has gradually replaced mercury lamps with lower power due to its advantages such as long service life and small size. At the same time, after the signing of the Minamata Convention on the international ban on mercury in 2013, there are only 3 years left before the total ban on mercury, which means that all traditional mercury lamp products will be replaced in the next 3 years, this policy will accelerate the arrival of large-scale application of UV LED.

The market is waiting for the outbreak, enterprises to accelerate the layout. In recent years, the main strategic route of UV LED enterprises is from capital chase to strong joint force terminal. This can be seen from the fact that foreign enterprise RayVio raised US $26 million with the help of UV LED technology that can be used for attractive new health care and hygiene products, to the acquisition of Jason by Yuanrong, and the announcement of Formosa Petrochemical to join hands with Japanese business Japan Machine Equipment (Nikkiso) to develop its UV-LED business.

However, after Formosa Petrochemical announced that it had joined hands with Japanese manufacturers to open up a large-scale layout mode for UV LED enterprises, Japanese manufacturers acquired AquiSense, a UV-C LED disinfection technology manufacturer in the United States, in order to expand the terminal market.

And Taiwan is also because of the red sea situation of LED blue light, UV LED has been laid out one after another. Among them, enterprises that have been laid out on the chip side for a long time have all adopted the trend of entering the terminal market. It is worth mentioning here that Guanghong and Jingjing have jointly built the terminal brand Bioraytron.

The joint efforts of these enterprises can be seen, UV LED enterprises for the future UV LED market into the overall trend of the strategy is based on the advantages of the enterprise's own chip, plus code to expand the terminal application market.

Application trend: consumer electronics and plant lighting are favored

According to the layout progress of UV LED enterprises, it is found that the future growth market of UV LED is in the field of terminal consumer electronics.

Among them is the foreign RayVio Corp, which claims to be able to provide medical-grade disinfection within 60 seconds, killing 99.9 percent of bacteria. Ellie, a medical-grade infant product sterilizer, can eliminate 99.98 percent of bacteria by irradiating the faucet with ultraviolet rays for 5 minutes. LG Innotek "UV LED module for water purifier faucet sterilization.

In addition to the terminal layout of foreign UV LED enterprises, domestic enterprises have also declined. Yuanrong has set up a big health brand to focus on the consumer electronics field. Tiandian Optoelectronics has also launched an overall plan for sterilization and disinfection of toothbrush boxes for consumer electronics products. The consumer electronics field has become a promising market for UV LED in the future.

In addition, UV LED in the field of water purification in recent years is a continuous breakthrough and progress, because the water purification field of the chip power requirements are relatively large, the chip is difficult to do in the past, but now the relevant enterprises have made a major breakthrough, have also begun to layout in the field of water purification.

It is worth mentioning that not long ago, the British AquiSense Technology Company developed the technology of ultraviolet LED modules using UV-C bands, which has been selected to be used in BIOWYSE projects in the international space field. This is a biological integration for space exploration. The control system plan will create an ecological control system that can be self-sufficient and can be used when humans explore the space universe.

In addition, UV LED can also be used in the field of plant lighting, because UV light has a regulatory function on the growth and development of plants, so it has been applied on a large scale in the field of agricultural lighting, and a new round of plant factory model will be UV LED get the largest play in another big field.

Technical progress: power breakthrough 100mW and wavelength record low 232nm

After talking about the progress in the application field and regarding the technological breakthrough, since this year, the domestic UV LED chip boss Yuan Rongjiesheng has once again achieved the technological breakthrough and released 100mW UVC LED products with a life of 10000 hours and 10mW UVC LED products and static water and flowing water sterilization modules based on HeaChips health chip technology last year.

According to Yuan Rong Jiesheng, the product is packaged in 6868 form and has a small overall volume, but it can emit 275nm deep ultraviolet rays of 100mW. At this time, the current public report on the power of * large deep ultraviolet products.

Compared with the deep ultraviolet LED power breakthrough, the research team of Cornell University in the United States can not be ignored. As we all know, the shorter the wavelength of the ultraviolet LED, the more difficult it is to do, and the team * developed a deep ultraviolet LED light source, setting the current industry deep-UV LED * low wavelength record of 232nm, breaking the previous record of 239nm set by the Japanese team.

According to the researchers, the technology uses atomic-level control of the interface of gallium nitride (GaN) and aluminum nitride (AlN) single-layer film for the reaction area, the successful emission of wavelengths between 232 to 270nm deep ultraviolet LED.

From the power exceeding 100mW to the wavelength setting a * low record of 232nm, the deep ultraviolet technology of UV LED has been greatly improved compared with the previous ones. Although the market of UVC LED is still in its infancy, the future growth space is indeed * large.
