Ukadaulo wa Ultraviolet (UV) wopha tizilombo toyambitsa matenda wakhala akuchita nyenyezi m'madzi ndi mpweya m'zaka makumi awiri zapitazi, chifukwa cha kuthekera kwake kupereka chithandizo popanda kugwiritsa ntchito mankhwala owopsa.

UV imayimira kutalika kwa mafunde omwe amagwera pakati pa kuwala kowoneka ndi x-ray pa ma electromagnetic spectrum. Mitundu ya UV imatha kugawidwanso kukhala UV-A, UV-B, UV-C, ndi Vacuum-UV. Gawo la UV-C limayimira kutalika kwa mafunde kuchokera ku 200 nm - 280 nm, kutalika kwa mafunde omwe amagwiritsidwa ntchito pazinthu zathu zopha tizilombo ta LED.
Mafotoni a UV-C amalowa m'maselo ndikuwononga nucleic acid, kuwapangitsa kuti asathe kubereka, kapena kuti asagwire ntchito ndi microbiologically. Izi zimachitika mwachilengedwe; Dzuwa limatulutsa kuwala kwa UV komwe kumachita motere.

Kumalo ozizira, timagwiritsa ntchito Light Emitting Diode (ma LED) kupanga ma photon apamwamba a UV-C. Kuwala kumapita ku ma virus, mabakiteriya ndi tizilombo toyambitsa matenda m'madzi ndi mpweya, kapena pamtunda kuti tizilombo toyambitsa matenda tisakhale ndi vuto m'masekondi.

Momwemonso momwe ma LED asinthira mafakitale owonetsera ndi kuyatsa, ukadaulo wa UV-C wa LED wakhazikitsidwa kuti upereke njira zatsopano, zotsogola, komanso zowonjezera pakuwongolera mpweya ndi madzi. Zotchinga pawiri, chitetezo chosefera pambuyo pa kusefera tsopano chilipo pomwe makina opangidwa ndi mercury sakanagwiritsidwa ntchito kale.

Ma LEDwa amatha kuphatikizidwa m'makina osiyanasiyana opangira madzi, mpweya, ndi malo. Makinawa amagwiranso ntchito ndi ma CD a LED kuti afalitse kutentha ndikuwongolera njira yopha tizilombo toyambitsa matenda.
