Microbes are the earliest forms of life on earth. We live in an environment where microbes are everywhere, in the air, in the kitchen, around the toilet, on the desk, on the phone, on our clothes… Bacteria and viruses are invisible to the naked eye and easily overlooked. Influenza virus (H1N1, H7N9, etc.) can lead to flu. E.coli can cause diarrhea and sepsis. S.aureus can set off pneumonia and pericarditis. What’s more, at the end of 2019, the outbreak of 2019-nCoV lead to pneumonia. Overall, pathogens are ever threatening human’s health.
Our ancestors have been using the sun to sterilize bacteria and viruses for a long time. Danish scientist Niels Ryberg Finsen (1860-1904) won the Nobel Prize in 1903 for his discovery that ultraviolet light could kill the tuberculosis virus. The International space station of America National Aeronautics and Space Administration（NASA）was one of the first to use UVC LEDs – Osram once conducted a market research study, the attendance rate of children in kindergartens increased by 1%~5% via reasonably standardized the use of ultraviolet sterilization lamps.
UVC exposure inactivates microbial organisms such as bacteria and viruses by altering the structure and the molecular bonds of their DNA (Deoxyribonucleic acid) and RNA (Ribonucleic Acid). DNA and RNA is a “blue print” these organisms use to develop, function and reproduce. By destroying the organism’s ability to reproduce, becoming harmless since it cannot colonize. After UVC exposure, the organism dies off leaving no offspring, and the population of the microorganism diminishes rapidly.
UVC sterilization, especially UVC LEDs sterilization technology is improving people’s well-being. Disinfection and sterilization of air, surfaces, and water. UVC LEDs help make the former sterilization ‘blind spots’ to be covered. Small size and portability is one of the highlights of UVC LEDs. “Follow the shape, follow the heart”. The miniaturization of the UVC LEDs chip and modules makes germicidal components extensive design space, and the small size makes them easy enough to embed in household appliances, such as refrigerators, air conditioners, washing machines, air purifiers. It can also be attached to a variety of living containers (water cups, lunch boxes, toothbrushes, bags, etc). In short, the UVC LEDs’ small size makes it possible to incorporate the technology into a broad range of consumer applications that help make people healthier and feel better.
Another highlight of the UVC LEDs is non-toxicity. In contrast to mercury lamps, which have deadly heavy metal and ozone (both of which are harmful to humans). UV LEDs use the same core semiconductor processes that are used to produce LEDs for illumination. The non-toxic feature allows UVC disinfection and sterilization to go directly into water purifiers and every corner of the home.
Convenience is another advantage of the UVC LEDs. Convenience of use not only comes from the miniaturization of the UVC LEDs, but also from its powerful germicidal efficiency. According to the current power and photoelectric conversion rate, the sterilization time of UVC LEDs is measured in the scale of “seconds”, and is operational in a mere flick of he switch. In contrast, detergents, disinfectants, photocatalysts and other sterilization methods are not only time-consuming and laborious, but also have external constraints (detergents, disinfectants to have water, photocatalyst to have light and air flow).
Taking care of you and your family’s health anytime and anywhere is the aim the UVC LEDs.
