Portable UVC LED mobile water sterilization module has been transferred to manufacturers and is expected to go public at the end of the year.

In order to overcome the problem of bacteria in water, the sterilization of drinking water on the market is mainly Ultraviolet (UV). According to the wavelength difference, UV can be divided into three kinds: ultraviolet A (UVA), ultraviolet B (UVB), ultraviolet C (UVC), especially UVC. The research institutes in Germany, Japan, the United States, Canada and other places are actively developing related technologies of UVC sterilization.

LED has been facing price competition in the Red Sea in recent years, while the UVC sterilization market is widely used. However, the existing traditional UVC filter light sterilization technology still relies on mercury lamp to produce UVC sterilization. It is not only bulky, light tube fragile, but also easy to generate mercury pollution problem, and also has great harm to the environment. The LED expert of Taiwan Institute of technology has been involved in the research of LED for a long time. Therefore, we want to find out a better solution for the industry from the best LED light source.

To develop the UVC LED light source, first of all, how to choose the right UVC wavelength on the LED light source, and try to detect the effect of various bands on the microorganism in the band between UVC 200nm and 280nm, and find the spectrum that accords with the absorption of bacteria and microorganism.

Immediately after facing the role of bactericidal action and optimizing the utilization of UVC light, the design of the mechanism was involved. So the research team constructed the channel that the water flow can best be illuminated by the UVC light source on the smallest area, and enhanced the UVC intensity of the projection water inlet channel, hoping to achieve the water flow of 2 liters per minute and eliminate the 9. More than 9.9% of E. coli can achieve the best germicidal efficacy.

The team has now combined with several LED factories in Taiwan to invest in R & D, and gradually establish an autonomous industrial chain of UVC LED in Taiwan area, creating a high value-added blue ocean market.

The portable UVC LED mobile water sterilization module has also been successfully transferred to manufacturers, and is expected to be available in the end of 2018 to allow more families to enjoy clean water resources. In the future, it can be applied to industries that attach great importance to water quality, such as biomedical industry and aquaculture industry. As long as the UVC LED mobile water sterilization module is installed at the water inlet and outlet, the water quality can be further improved.

At present, because of its small size and easy installation, the technology can be carried and installed at the outlet terminals. It is not only suitable for general homes, but also for disaster emergency. For example, when the earthquake or other disasters occur, the clean water can be quickly supplied to the public by using this aquatic product, and this technology is also placed in the 2018 place. The world's top 100 science and technology awards.

Zhu Mudao, director of the electro-optic system of the Research Institute, said that through such technological development, not only can it save costs, but also skip the restrictions.
