Deep UV LED disinfection What is behind the black technology

Date:2018-07-30 Reading number:

Have you heard of artificial satellites, "artificial light" that can be disinfected? Have you heard of it? "Artificial light" can also be disinfected? A few days ago (July 25-27), 4332 whole-class pregnant and baby brands from all over the world were unveiled in the 18th CBME China Pregnancy and Children's Wear Exhibition (hereinafter referred to as 2018CBME China).

The exhibition opened in the National Convention and Exhibition Center (Shanghai), a large number of "new and unique" products earned enough attention, and the debut of deep ultraviolet LED disinfection technology has caused a crowd. Applying black technology to the field of disinfection of baby products not only meets the new needs of the modern family lifestyle, but also drives the new growth of the baby and child industry.

Deep ultraviolet rays, "artificial light" for disinfection

Ultraviolet light is very common. It is light with a wavelength of 10 to 400 nanometers (nm) in sunlight. It can be classified into UVA, UVB, and UVC according to different wavelength bands. Among them, UVC (wavelength 200 ~ 275nm) can penetrate the cell membrane and nucleus of the organism, destroy DNA, and play the role of killing various pathogens, such as bacterial propagules, spores, viruses, fungi and so on.

However, the UVC in the sun is blocked by the ozone layer and cannot reach the earth and cannot be used by people. Therefore, LED deep ultraviolet light - a bunch of artificial "sunlight" with a special band was born.

As a leading brand in the field of LED disinfection, “59 seconds” has undergone extensive market research and tailored a series of disinfection products to meet the needs of users.

At present, the post-90s mother group has become the main force of market consumption. Their demand for high-quality life is directly reflected in the consumption level. The trend of minimalism, individualization and fashion consumption has become more and more obvious. The application of deep ultraviolet LED disinfection black technology is very attractive to this young consumer group.

Select a specific band to maximize disinfection

However, not all wavelengths of UV light can have a strong disinfection effect. LED disinfection technology selects a specific band (260-280nm), which is most easily absorbed by nucleic acids (substances that affect the reproduction and survival of bacteria and viruses). Ultraviolet rays can destroy chemical bonds in nucleic acid molecules and cause decomposition of nuclear proteins or nucleic acids. And denaturation, causing the synthesis of proteins and enzymes in bacteria, thereby achieving the purpose of sterilization.

In addition, some disinfection products on the market choose ultraviolet light of about 185 nm. This band of ultraviolet light illuminates oxygen molecules, which will decompose oxygen molecules to produce harmful gas ozone. This is a big problem for the mother group like the "coward". The LED disinfection technology does not use the band of 185 nm as the medium, does not produce harmful gases such as ozone; does not use mercury as a medium, does not produce secondary pollution; does not add any chemicals, and is truly green.

Exquisite manufacturing process, the chip is more expensive than gold

LED disinfection technology, which was first used to build the decontamination module components of the International Space Station project, plays an important role in the water disinfection of Yu Aviation Station. 8000 chips are only 1g heavy. To some extent, 1g LED disinfection chips are more expensive than 100g gold.

An LED disinfection chip is only 0.5mm x 0.5mm, which is equivalent to a slight trace of the refill on white paper. 8000 chips only have a weight of 1g, but such a small chip may require thousands of processes. In order to complete, the production process is complicated.

Since the UVC energy generated by the LED is huge, it is easy to damage the lamp auxiliary material, which has almost strict requirements on the manufacturing technology. In order to prevent the copper oxidation from affecting the deep ultraviolet performance and increasing the service life of the lamp bead, the bracket portion of each UVC lamp bead is subjected to copper plating pure gold treatment.

“The disinfection field for the maternal and child market is the first step for our '59 second' brand to enter the global disinfection market. Next, we will be fully developed in the field of home life, beauty and tourism.” 59 second brand founder In this way, he also said that the company is currently focusing on the research of deep-UV LED disinfection technology, and there is still much room for improvement in chip development and packaging technology.
