[UVLED Sterilization] Popular Science of UV LED Sterilization Disinfection

Ultraviolet rays are a high -energy light wave with high energy, the naked eye cannot be recognized. Its wavelength is less than 400nm, which exists outside the outer side of the visible spectrum ultraviolet end, so it is called ultraviolet rays. By wavelength range divided into UV-A (320nm 400nm), UV-B (275nm 3 2 0 n m), UV-C (2 0 nm 2 7 5 nm), UV-D (100nm 200nm) four This band, wherein A, B, and C, three bands are also called disinfected ultraviolet rays. The three bands of A, B, and C have a certain disinfection effect, especially for the best disinfection effect with the C band. Light quantum theory believes that light is a special form of material movement. Each wavelength of 253.7nm UV photon has 4.9EV energy. The disinfection and sterilization of the UV line to water is mainly the maximum absorption wavelength (254nm) of nucleic acid (DNA). DNA can absorb high -energy ultraviolet radiation, cause adjacent alkali -based dislocation, and form pyrimidinedimer; Nucleic acid copy and protein expression leads to apoptosis. At present, research is limited to the research of the traditional ultraviolet-rays, and UV-LED as a new type of disinfection process may be more or less different from the traditional disinfection mechanism.
