Every year, about 3 million people worldwide die from water pollution and air pollution and bacteria. RayVio is trying to use the patented deep ultraviolet LED technology to produce healthy microchips, providing cleaner and digital sterilization methods to solve the current market sterilization of mercury lamps. It is fragile, easy to produce harmful chemicals, large in size, short in life, and unable to be digitally controlled. It will bring better health to people still living in areas affected by bacteria, water pollution and air pollution. In response, the reporter interviewed RayVio's China Development Manager Paul, who had a detailed understanding of RayVio.
Mercury UV lamp achievements and defects
Humans have been using ultraviolet light in sunlight for sterilizing very early. Scientists at home and abroad have been studying ultraviolet light for more than 200 years. Since Dr. Heraeus of Germany invented the first ultraviolet germicidal lamp, UV sterilization technology It is widely used in medicine, drinking water and food, especially in air sterilization, surface sterilization, and water treatment sterilization.
During the period of SARS, it began to enter various public places and even families. Some are similar in appearance to fluorescent lamps for home use. At present, there are not a few ordinary families who buy it.
The scientific principle of ultraviolet disinfection: mainly acts on the DNA of microorganisms, destroys the DNA structure, and makes it lose the function of reproduction and self-replication to achieve the purpose of sterilization. Ultraviolet sterilization has the advantages of colorless, odorless and chemical-free, and has been replacing traditional chlorine and bleaching powder sterilization technologies in the field of water treatment. Since the beginning of the actual UV water treatment plant in Canada in 1982, the technology has been widely adopted in the United States, Europe, and India.
Mercury lamps (also called mercury lamps) have made great contributions to disinfection and sterilization. However, mercury lamps have some drawbacks: First, they are easily damaged, and mercury after damage can cause harm to people. The second is that it is too bulky to carry, requires a certain start-up time, and is poor in design. At the same time, mercury lamps emit ozone when they work, which is harmful to human health.
In the middle of the 20th century, there were serious mercury pollution incidents caused by illegal discharge of pollutants from factories in Japan, causing waterlogging and hundreds of deaths. In January 2013, 92 countries around the world signed the International Convention on Water Margin in Kumamoto, Japan. Under the terms of the Minamata Convention, the State party will ban the production, import and export of mercury-added products by 2020, for example, some batteries, some fluorescent lamps, some mercury-added medical supplies such as thermometers and sphygmomanometers.
Therefore, the market needs to be smaller, portable, more stable, not easily damaged, can be personalized, and does not produce healthy ultraviolet disinfection technology such as ozone and other harmful chemicals. It is best to implement digital control, and control the UV lamp to control the disinfection time, distance, power, etc. at the required time.
Practical technology entrepreneurs can always find Bole
Dr. Liao Wei, the founder of RayVio, studied at Boston University in the United States, and his research direction is deep ultraviolet LED technology. During his Ph.D. study, Liao Wei developed a new semiconductor material and process technology, which made the deep-UV LED chip produced by this method more powerful and lower cost, and made this technology into the consumer market possible. And RayVio has the ability to grow chips, epitaxial packaging, and high technical barriers.
After graduating from the Ph.D., Liao Wei first entered the Philips company as a senior scientist, but has been looking for opportunities to apply his own technology entrepreneurship. He began to look for investment around 2011. At this time, he met the company's current CEO Dr. Rober Walker.
At the time, Robert was a partner at Sierra Ventures, a Silicon Valley veteran venture capital firm. "I am optimistic about the business prospects of this technology. In addition, for example, in the field of water cleaning, it is also very beneficial to society."
Robert said in a news interview that he has more than 20 years of experience in the LED field. Before he started venture capital, he founded a large LED production company, but he saw that Liao's technology can sterilize deep ultraviolet LED. Applied in the civilian sector, I am very happy and willing to join RayVio as CEO. Recently, the former US GAP clothing company's VP, former Misfit wearable company's CMO (Chief Marketing Officer) Matthew Lloyd also joined RayVio as a CMO.
Ellie's usage scene
In November, RayVio launched RayVio's first to C product designed to create a cleaner sanitation environment for infants and toddlers in outdoor and mobile settings on the famous American crowdfunding platform Indiegogo. Ellie - the world's first to use its core TRUVIOLET Portable baby product sterilizer for deep UV technology. They reached their crowdfunding goals within two days. As of now, there are nearly 700 supporters, and the crowdfunding amount has reached 74,000 US dollars.
Let's take a look at an application scenario of this technology to make it more practical. The following animation is the process of disinfecting baby products with this technology. Paul introduced this sterilization process in 60 seconds, only 1/30 of the time of traditional cooking sterilization, saving time and effort. Its portability also solves the drawbacks of cooking and disinfecting children's products in non-family scenes such as parent-child travel in the outdoors.
Ellie is about the same length as an ipad. It is 9.4 cm deep and weighs 0.9 kg. It can be placed in the mother's travel bag. It can kill 99.9% of the bacteria on the bottle in 60 seconds, including Salmonella, Listeria, E. coli and other bacteria that can cause illness or even death to the baby. The product retails for $129 and can be used for up to a week for 20 times a day. At present, the product is pre-sold at the preferential price of US$99 on the official website of China.
