This lamp generates a rich amount of ultraviolet light at 253.7 nm, which has the strongest sterilizing power.
Ultraviolet (UV) light has different properties depending on the wavelength, and each plays an important role. The range of UV wavelengths is considered to be 100 to 400 nm (nanometers: 1 nm = 10^-7 cm), and it is classified into UV-C (shortwave) from 100 to 280 nm, UV-B (medium wave) from 280 to 315 nm, and UV-A (longwave) from 315 to 400 nm. Various types of UV discharge lamps are used as the most efficient means to artificially produce these wavelengths. UV sterilization lamps are lamps that generate a high amount of the most potent sterilizing UV light at 253.7 nm within the UV-C range. Sterilization using UV light is effective against almost all types of bacteria, viruses, and molds. Simply turning on the sterilization lamp can achieve disinfection, making it easy to use and economical in terms of equipment and maintenance costs. Additionally, there is a wide variety of sterilization lamps available, allowing for different applications to be tailored accordingly. Leveraging these features, sterilization lamps are utilized as highly accurate sterilization methods in many fields such as food, healthcare, cosmetics, and electronics, as well as in everyday applications like disinfecting drinking water and indoor air.
