The development of a new type of high efficiency deep ultraviolet sterilization LED lamp

A research team in Japan announced on 10, they successfully developed a deep ultraviolet germicidal lamp, LED model, compared with the traditional low-pressure mercury lamp, has the advantages of small size, energy saving, environmental protection, long life and other advantages.

According to Japan's Jiji news agency reported that 10 sites in medical and food industry, often using low-pressure mercury lamp sterilization, but because Mercury is likely to cause harm to the environment, so the researchers wanted to find excellent green alternatives. Deep UV is a relatively short wavelength of ultraviolet light, killing bacteria and viruses are more efficient.

The brightness, luminous efficiency and service life of the deep UV LED lamp with a wavelength of about 260 nm are affected by the crystallization of the substrate. The research team from Tokyo University Agricultural & Technology and the chemical composition of Tokuyama company, developed a technology can be made of high purity aluminum nitride crystal, and then get the high performance of the substrate crystal, ensure sterilization effect and service life of the LED lamp.

According to reports, this new type of deep UV LED lamp can only use a dry battery can be used for portable sterilization and sterilization of liquid culture. This technology has been patented in Japan and the United states. Tokuyama chemical company plans to further improve product performance, for in 2015 the market.
