Have you heard of artificial satellite, the "artificial light" that can disinfect? Can artificial light disinfect? A few days ago (July 25-27), 4332 pregnant and infant brands from all over the world appeared one by one in the 18th CBME China pregnant and infant exhibition and children's clothing exhibition (hereinafter referred to as 2018cbme China).

The exhibition opened in the National Convention and Exhibition Center (Shanghai), a large number of "new strange" products earned enough attention, and the appearance of deep UV LED disinfection technology caused onlookers. The application of black technology in the field of disinfection of baby care products not only meets the new needs of modern family lifestyle, but also drives the new growth of pregnancy and infant industry.

Deep ultraviolet, artificial light for disinfection

Ultraviolet is very common, it is the sunlight wavelength 10 to 400 nm (nm) light, according to different bands can be divided into UVA, UVB, UVC. Among them, UVC (wavelength 200-275nm) can penetrate biological cell membrane and nucleus, destroy DNA and kill various bacteria, such as bacterial propagules, spores, viruses and fungi.

However, UVC in the sunlight will be blocked by the ozone layer, can not reach the earth, can not be used by people. Therefore, led deep ultraviolet - a special band of artificial "Sunlight" was born.

As a leading brand in the field of LED disinfection, "59 seconds" has customized a series of disinfection products according to the needs of users' pain points after a lot of market research.

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

Select a specific band to maximize the disinfection effect

However, not all bands of UV can have a strong disinfection effect. Led disinfection technology chooses a specific band (260-280nm). This band is most easily absorbed by nucleic acids (substances that affect the reproduction and survival of bacteria and viruses). Ultraviolet light will destroy the chemical bonds in nucleic acid molecules, cause the decomposition and denaturation of nuclear protein or nucleic acid, and cause the synthesis obstacles of protein and enzyme in bacteria, so as to achieve the purpose of sterilization.

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

Exquisite manufacturing technology, chips are more expensive than gold

Led disinfection technology, the first decontamination module used in the international space station project, plays an important role in the water disinfection of the space station. 8000 chips only weigh 1g. To some extent, 1g led disinfection chips are more expensive than 100g gold.

The volume of an LED disinfection chip is only 0.5mm x 0.5mm, which is equivalent to the trace of pen refill on white paper. 8000 chips only weigh 1g, but such a small chip may need thousands of processes to complete, which shows the complexity of the manufacturing process.

Due to the huge UVC energy produced by LED, it is easy to damage the auxiliary material of lamp beads, which has almost stringent requirements for manufacturing technology. In order to prevent copper oxidation from affecting the deep ultraviolet performance and increase the service life of the lamp beads, the bracket part of each UVC lamp bead is treated with copper plating with pure gold.

"The field of disinfection for the maternal and infant market is the first step for our" 59 seconds "brand to enter the global disinfection market. Next, home life, beauty and tourism will be in full swing. " 59 seconds brand founder said, he also said that at present the company focuses on the research of deep UV LED disinfection technology, and there is still a lot of room for improvement in chip development and packaging technology.
