Japan to develop new and efficient deep ultraviolet germicidal LED lights
2013/1/11
A Japanese research team announced on the 10th they successfully developed a new efficient deep UV germicidal LED lights and traditional low-pressure mercury lamp, small size, energy saving, environmental protection, long life and other advantages.

According to Japan's Jiji Press reported, in the field of medical care and food, often using a low pressure mercury lamp sterilization, mercury easily cause harm to the environment, so researchers have been hoping to find excellent environmentally friendly alternative. The Deep Ultraviolet is a relatively short wavelength ultraviolet light, high efficiency to kill bacteria and viruses.

Brightness of LED lights of the wavelength of about 260 nm deep ultraviolet light, the light-emitting efficiency and lifetime by the influence of the substrate crystal. Tokyo University of Agriculture and Tokuyama chemical composition of the research team, developed a can made ​​of high purity aluminum nitride crystal technology, and then get the current high-performance substrate crystal, and ensure sterilization effect and service life of the LED lights .

According to reports, this new type of deep UV LED lights only use dry batteries will be able to work, and can be used for portable sterilization device, and culture medium sterilization. This technology has been made in Japan and the United States the basic patent. Tokuyama Chemical Company plans to further improve product performance, and strive for the products to market in 2015.
