The covid-19 epidemic has spread all over the world. Driven by the business opportunities for epidemic prevention, the demand for deep ultraviolet ray (UVC) LED (wavelength ≤ 280nm) with sterilization effect has increased dramatically , resulting in a total shortage of goods in the supply chain.
Ultraviolet (UV) contains four brothers: UVA/UVB/UVC/UVD, According to the CIE (international commission on illumination) standard, the spectrum range from 100nm to 400nm is called ultraviolet spectrum. The bactericidal ultraviolet wavelengths are concentrated between 200nm and 300nm .
Now UV lighting includes UVC-LED and UVC mercury lamp in the market.
Ultraviolet mercury lamps have the advantage of high light power and are mainly used in large space sterilization and disinfection, such as schools and hospitals.
However, UV LED does not need warm-up time and does not use mercury, so it has the advantages of environmental protection, long life, energy saving and less heat loss.
In the past years, the continuous business of UVC LED chip and packaging manufacturers are all optimistic about the business opportunities of UVC LED outbreak, including Seoul Viosys, Asahi Kasei (Crystal IS), Stanley, Bioraytron and SAN 'an.
So in the next few years, deep UV LED instead of low-pressure mercury lamp as ultraviolet sterilization lamp light source, will be the general trend, but it should take some time.
Looking forward to the future, UVC LED manufacturers have a bright profit prospect in this round, and have increased the capital expenditure on production and r&d, . After the release of new production capacity, there will be a good situation of phased increase in volume and price. In the long run, with the expansion of UVC LED production and application scale, the average production cost is expected to continue to decline, and the market penetration rate in the post-epidemic era still has a lot of room to increase.
Ultraviolet wavelength difference
| UV-A | 315nm-400nm |
| UV-B | 280nm-315nm |
| UV-C | 100nm-280nm |
