A new generation of cutting-edge technology, called deep ultraviolet leds, emits light that kills germs and is invisible to the naked eye. This bactericidal light is called deep ultraviolet. The LED field is now being developed to release "UV-C", the type of light that ranges from 100 to 280 nanometres (billionths of a billionth of a nanometer).

The power of deep uv rays has long been proven. Deep uv rays act directly on the DNA that is the basis of life, essentially cutting off bacterial reproduction. Studies have shown that deep ultraviolet rays with a wavelength of 260nm are particularly easily absorbed by DNA. Has the effect of destroying DNA genetic information.

Deep UV development

Deep UV technology is mainly developed in the United States, Japan, South Korea and other countries. In 2014, Akasaki and Amano won the Nobel Prize in Physics for developing blue leds. With its Nobel Prize in technology, Japan is now at the forefront of deep uv development. The United States takes the lead in deep ULTRAVIOLET research, and the representative enterprise is the SETI company of the United States. However, in recent years, it has been surpassed by Japan. NIKKISO of Japan began to mass produce deep ultraviolet LED with luminescence wavelength of 255 ~ 350nm in the spring of 2015.
