  2. Ultraviolet germicidal irradiation - Wikipedia

    en.wikipedia.org/wiki/Ultraviolet_germicidal...

    A UVGI system is designed to expose environments such as water tanks, rooms and forced air systems to germicidal UV. Exposure comes from germicidal lamps that emit germicidal UV at the correct wavelength, thus irradiating the environment. The forced flow of air or water through this environment ensures exposure of that air or water.

  3. Germicidal lamp - Wikipedia

    en.wikipedia.org/wiki/Germicidal_lamp

    A germicidal lamp (also known as disinfection lamp or sterilizer lamp) is an electric light that produces ultraviolet C (UVC) light. This short-wave ultraviolet light disrupts DNA base pairing , causing formation of pyrimidine dimers , and leads to the inactivation of bacteria , viruses , and protozoans .

    en.wikipedia.org/wiki/Far-UVC

    Unlike conventional germicidal UV-C lamps, which are limited to upper-room (above people's heads [8]) pathogen inactivation or use in unoccupied spaces, due to their negative effects on human skin and eyes, far-UVC is considered promising for whole-room pathogen inactivation due to its enhanced safety. The installation of far-UVC lights on ...

    en.wikipedia.org/wiki/Sterilization_(microbiology)

    Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.

  7. Gas-discharge lamp - Wikipedia

    en.wikipedia.org/wiki/Gas-discharge_lamp

    A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
