Ukadaulo wothira majeremusi wa Ultraviolet (UV) wakhala wotchuka kwambiri pakuchiza madzi ndi mpweya m'zaka makumi awiri zapitazi, chifukwa cha kuthekera kwake kupereka chithandizo popanda kugwiritsa ntchito mankhwala owopsa.

UV imayimira mafunde a dzuwa omwe amagwera pakati pa kuwala kooneka ndi x-ray pa electromagnetic spectrum. Mtundu wa UV ukhoza kugawidwanso m'magulu a UV-A, UV-B, UV-C, ndi Vacuum-UV. Gawo la UV-C limayimira mafunde a dzuwa kuyambira 200 nm mpaka 280 nm, mafunde omwe amagwiritsidwa ntchito mu zinthu zathu zophera majeremusi za LED.
Ma photoni a UV-C amalowa m'maselo ndikuwononga nucleic acid, zomwe zimapangitsa kuti asabereke, kapena kuti asagwire ntchito m'thupi. Izi zimachitika m'chilengedwe; dzuwa limatulutsa kuwala kwa UV komwe kumachita motere.

Pa nthawi yozizira, timagwiritsa ntchito ma LED kuti tipange ma photon ambiri a UV-C. Ma radiation amalunjika ku ma virus, mabakiteriya ndi tizilombo tina tomwe timalowa m'madzi ndi mumlengalenga, kapena pamwamba kuti tizilomboto tisavulale pakapita masekondi.

Mofanana ndi momwe ma LED asinthira makampani owonetsera ndi kuunikira, ukadaulo wa UV-C LED ukukonzekera kupereka njira zatsopano, zabwino, komanso zokulirapo pakukonza mpweya ndi madzi. Chitetezo cha zotchinga ziwiri, choteteza pambuyo posefera tsopano chikupezeka komwe makina opangidwa ndi mercury sakanatha kugwiritsidwa ntchito kale.

Ma LED awa amatha kuphatikizidwa m'machitidwe osiyanasiyana kuti azitha kuchiza madzi, mpweya, ndi malo. Machitidwewa amagwiranso ntchito ndi ma CD a LED kuti afalitse kutentha ndikuwonjezera magwiridwe antchito a njira yophera tizilombo toyambitsa matenda.
