Pofuna kuthana ndi vuto la mabakiteriya m'madzi, zoletsa zamadzi akumwa pamsika zimakhala zotseketsa ma ultraviolet (UV). Malinga ndi kusiyana kwa kutalika kwa mawonekedwe, kuwala kwa ultraviolet kungagawidwe kukhala ultraviolet A (UVA), ultraviolet B (UVB) ndi ultraviolet C (UVC), pakati pawo UVC ili ndi mphamvu yoletsa yoletsa kwambiri. Pakadali pano, mabungwe ofufuza ku Germany, Japan, United States, Canada ndi madera ena akupanga ukadaulo wokhudzana ndi kulera kwa UVC.

M'zaka zaposachedwa, LED yayang'anizana ndi nyanja yofiyira ya mpikisano wamitengo, ndipo msika wa UVC wopha tizilombo toyambitsa matenda ndi wosabala umagwiritsidwa ntchito kwambiri. Komabe, ukadaulo womwe ulipo kale wa UVC zosefera zosefera madzi zimatengera nyali ya mercury kuti ipangitse kutseketsa kwa UVC. Silikulu kokha mu voliyumu komanso yosalimba mu chubu la nyali, komanso sachedwa kuipitsidwa ndi mercury komanso kuwononga chilengedwe. Akatswiri otsogola ochokera ku Taiwan Industrial Research Institute akhala akuchita kafukufuku wokhudzana ndi LED kwa nthawi yayitali, kotero akufuna kuyamba ndi gwero lawo labwino kwambiri la kuwala kwa LED kuti apeze mayankho abwinoko pamakampaniwo.

Kupanga gwero la kuwala kwa UVC LED, choyamba tiyenera kuyang'ana momwe tingasankhire mawonekedwe olondola a UVC pa gwero la kuwala kwa LED, ndikuyesa kukopa kwamagulu osiyanasiyana pazachilengedwe pakati pa UVC 200nm ndi 280nm, kuti tipeze mawonekedwewo mogwirizana ndi kuyamwa. Kenako tiyenera kuyang'anizana ndi momwe tingagwiritsire ntchito bwino ntchito yoletsa kulera ndi kukhathamiritsa kagwiritsidwe ntchito ka kuwala kwa UVC, komwe kumakhudza kapangidwe ka makinawo. Choncho, gulu lofufuza limapanga njira yomwe madzi amatha kuyatsidwa kwambiri ndi kuwala kwa UVC m'dera laling'ono kwambiri, ndikuwonjezera mphamvu ya UVC ya njira yolowera yolowera, ndikuyembekeza kuti madzi akuyenda 2 malita pamphindi ndi kuchotsa oposa 99.9% a E. coli, Pezani njira yabwino kwambiri yoletsa kulera. Gulu laika ndalama ku R & D kuphatikiza ndi opanga ambiri akuluakulu a LED ku Taiwan, pang'onopang'ono adakhazikitsa unyolo wathunthu wamakampani odziyimira pawokha a UVC otsogola ku Taiwan, ndikupanga msika wam'madzi wam'madzi wamtengo wapatali kwambiri.

"Portable UVC led mobile water sterilization module" yasamutsidwanso bwino kwa opanga. Akuyembekezeka kulembedwa kumapeto kwa 2018, kuti mabanja ambiri azisangalala ndi madzi aukhondo. M'tsogolomu, itha kugwiritsidwa ntchito m'mafakitale omwe amaphatikiza kufunika kwa madzi, monga makampani azachipatala ndi mafakitale apamadzi. Malingana ngati gawo la UVC lotsogolera madzi oyendetsa madzi limayikidwa polowera madzi ndi kutuluka, khalidwe la madzi likhoza kuwonjezereka.Pakalipano, chifukwa cha kukula kwake kochepa komanso kosavuta, lusoli likhoza kunyamulidwa ndikuyika mofulumira pamadzi aliwonse. potuluka. Sikoyenera kokha kwa nyumba wamba, komanso ingagwiritsidwe ntchito poyankha mwadzidzidzi m'madera atsoka. Mwachitsanzo, pakagwa chivomezi kapena masoka ena, mankhwalawa amatha kupereka anthu mwachangu madzi owuma, aukhondo komanso otetezeka. Tekinolojeyi imatchulidwanso mumpikisano wapamwamba kwambiri wa 100 padziko lonse lapansi wa 2018. Zhu Mudao, mkulu wa Institute of electro-optical systems ya Industrial Research Institute, adanena kuti kupyolera mu chitukuko chaumisiri wotero, sitingathe kupulumutsa ndalama zokha, komanso. chotsani zoletsa pakugwiritsa ntchito.
