1. Speaking of the UV-LED field that has attracted much attention this time, research reports show that deep ultraviolet LEDs featuring high-tech innovation are widely used and will become a new hot spot in global LED research and investment. Ultraviolet LED light source is a technology that has only begun to expand in the past 2 to 3 years. Among them, the UV-A band is about 320~400nm, the UV-B is 290~320nm, and the UV-c band is 240~290nm. The uv-A and UV-c quilt segments have the greatest market potential. From the perspective of the production technology of LED components, the shorter the wavelength, the more difficult it is to make. Compared with the current blue LED dies, the Chinese mainland market can Shortcuts can be obtained by throwing money or digging corners, but the crystal production of uVLED is difficult, and the technical threshold is more than 1o times more difficult. Especially for short-wave band manufacturers, there are relatively few manufacturers, which can not be solved by digging corners.
⒉. The high technical threshold and scarce equipment make the survival of UVLED companies always rely on "blood supplementation." Because technology and price have not yet reached the time to enter the market on a large scale, it is still a long day before the market returns. Before that, companies need a lot of investment to maintain R&D costs and equipment investment, and the country does not currently have relevant funds. Policy support mainly relies on market-oriented venture capital. What is gratifying is that the current National 863 Program has attached great importance to UVLED technology and established projects, which will drive enterprises to pay more attention, and naturally more enterprises will participate.
3. Committed to the R&D and manufacturing of high-reliability UV LEDs. Expansion of optoelectronic products covering UVA, UvB, Uvc fields (260-430nm), widely used in banknotes and anti-counterfeiting, nail phototherapy, mosquito and insect repellent, photocatalyst air purification, industrial light curing, deep ultraviolet sterilization, medical treatment, non-destructive inspection and inspection Leakage, fluorescence detection, jewelry identification, plant growth and other fields.
4. In addition, LED applications in the medical field generally require light sources with high color rendering properties, low heat generation, and high stability. This is also a niche market worthy of attention for UV LEDs. In particular, the ultraviolet light around 375nm and 280nm can be used in air cleaners, water purifiers, and the purification of environmental hormones, pesticides, etc. Exciting the photocatalyst with these two wavelengths of light sources has better bactericidal power; among them, the strong bactericidal power of 280nm UV LED chips is under continuous research.
