Icyorezo cya Koronavirusi cyashyize abantu mu mpungenge zo kuba bagiteri zikikijwe, kandi cyagize ingaruka zikomeye ku buzima bwa buri munsi bw'abantu ndetse n'imikorere isanzwe ya sosiyete. Mu gihe cy'ihumana rikomeye ry'ibidukikije, habayeho ikoranabuhanga ryo kurwanya imirasire y'urumuri rwa ultraviolet rwinshi, ryageze ku ntambwe ikomeye mu bijyanye no kurwanya imirasire y'urumuri kandi rifite amahirwe menshi ku isoko. Mu gihe cy'icyorezo, ibicuruzwa bya UVC LED ultraviolet byabaye ibicuruzwa bigurishwa cyane mu kurwanya imirasire y'urumuri no kuyirinda indwara bitewe n'inyungu zabyo zo kuba ari nto, gukoresha ingufu nke, kutabangamira ibidukikije, no kubona amatara ako kanya.
Kubera iterambere ry’inganda za LED za UVC, inganda zo gucapa nazo zazanye amahirwe yo guhindura no kuvugurura, ndetse n’inganda zose z’urumuri rwa UV zazanye amahirwe yo guhindura no kuvugurura. Mu 2008, kugaragara bwa mbere kw’ikoranabuhanga rya LED UV mu imurikagurisha ry’ikoranabuhanga n’ibikoresho bya Drupa mu Budage byari bitangaje kandi byakuruye abantu benshi, bikurura cyane abakora ibikoresho byo gucapa n’abatanga serivisi zo gucapa. Impuguke ku isoko ry’icapiro zashimiye cyane iri koranabuhanga, kandi zizera ko ikoranabuhanga rya LED UV rizaba ikoranabuhanga nyamukuru ryo gutunganya mu nganda z’icapiro mu gihe kizaza.
Ikoranabuhanga ryo gupima urumuri rwa UV LED
Ikoranabuhanga ryo gukaraba UV LED ni uburyo bwo gucapa bukoresha diode zitanga urumuri za UV-LED nk'isoko y'urumuri. Bufite ibyiza byo kuramba, ingufu nyinshi, ingufu nke zikoreshwa, kandi nta mwanda uhumanya (mercury). Ugereranyije n'urumuri rusanzwe rwa UV (itara rya mercury), ubugari bwa spectral bwa UV LED ni buto cyane, kandi ingufu zizaba zirimo imbaraga nyinshi, ubushyuhe buke, ingufu nyinshi zikoreshwa, kandi imirasire ingana. Gukoresha urumuri rwa UV-LED bishobora kugabanya gusesagura umutungo w'icapiro no kugabanya ikiguzi cyo gucapa, bityo bikagabanya igihe cyo gukora amasosiyete acapa no kunoza cyane imikorere y'amasosiyete.
Ni ngombwa kuvuga ko ikoranabuhanga rya UV LED rikoresha umugozi wa ultraviolet uri hagati ya 365nm na 405nm, uri mu mugozi wa ultraviolet muremure (uzwi kandi nka UVA band), nta kwangirika kw'imirasire y'ubushyuhe, bishobora gutuma ubuso bwa wino ya UV bwuma vuba kandi bikanoza ubwiza bw'umusaruro. Ingano y'uburebure bw'umugozi ikoreshwa mu rwego rwo kurwanya imirasire ya ultraviolet iri hagati ya 190nm na 280nm, uri mu mugozi mugufi wa ultraviolet (uzwi kandi nka UVC band). Uyu mugozi w'urumuri rwa UV ultraviolet ushobora kwangiza imiterere ya ADN na RNA y'uturemangingo na virusi, kandi ugatera urupfu rwihuse rwa mikorobe.
Ikoreshwa ry'ikoranabuhanga ryo gusiga UV LED n'inganda zikora ibikoresho by'abanyamahanga
Aztec Label, ikigo gikomeye mu ikoranabuhanga rya MicroLED, yatangaje ko cyubatse kandi gishyiraho sisitemu yacyo nini cyane yo kumisha UV ya LED, izahindura umusaruro wayo wose w’uruganda muri ubwo bwoko bw’ikoranabuhanga mu mpera z’umwaka. Nyuma yo gushyiraho sisitemu ya mbere yo gukamura UV ya LED ku imashini y’amabara abiri umwaka ushize, iyi sosiyete irimo gushyira sisitemu ya kabiri yo gukamura UV ya Benford ku cyicaro cyayo cya West Midlands kugira ngo igabanye ikoreshwa ry’amashanyarazi.
Ubusanzwe, gukoresha ikoranabuhanga rya LED UV icapa bishobora gutuma wino yumuka mu kanya gato. Itara rya LED UV rya sisitemu ya Aztec Label rishobora gucanwa no kuzimwa ako kanya, nta gihe cyo gukonjesha gisabwa, kandi rikozwe muri LED UV diode, bityo igihe giteganijwe cyo gukora ibikoresho byaryo gishobora kugera ku masaha 10.000-15.000.
Muri iki gihe, kuzigama ingufu no "karubone ebyiri" biri kuba kimwe mu byerekezo by'ingenzi byo kuzamura inganda zikomeye. Colin Le Gresley, umuyobozi mukuru wa Aztec Label, na we yagaragaje uburyo isosiyete yibanda kuri iyi ngeso, asobanura ko "kuramba biri kuba ikintu cy'ingenzi gitandukanya ibigo n'abakiriya ba nyuma".
Colin Le Gresley yanagaragaje ko mu bijyanye n'ubwiza, ibikoresho bishya bya Benford Environmental LED UV bishobora gutanga umusaruro wo gucapa ku giciro gito n'amabara meza, bigatuma ubwiza bwo gucapa buhora buhagaze neza kandi nta bimenyetso bihari. “Mu rwego rwo kubungabunga ibidukikije, bikoresha ingufu nke cyane, birenga 60% munsi y'ingufu zisanzwe za UV. Hamwe no guhinduranya ako kanya, diode ziramba n'ibyuka bihumanya ikirere bike, bitanga umusaruro mwiza abakiriya biteze, mu gihe bihuye neza n'intego zacu zo kubungabunga ibidukikije.”
Kuva bashyiramo sisitemu ya mbere ya Benford, Aztec Label yashimishijwe n'imiterere yayo yoroshye kandi ifite umutekano ndetse n'umusaruro w'imikorere. Kuri ubu, isosiyete yafashe icyemezo cyo gushyiraho sisitemu ya kabiri nini.
Incamake
Ubwa mbere, hamaze kwemezwa kandi hagashyirwa mu bikorwa "Amasezerano ya Minamata" mu 2016, gukora no gutumiza no kohereza mu mahanga ibicuruzwa birimo mercure bizahagarikwa kuva mu 2020 (amatara menshi asanzwe ya UV akoresha amatara ya mercure). Byongeye kandi, ku ya 22 Nzeri 2020, Ubushinwa bwatanze urugero mu nama ya 75 y'Inteko Rusange y'Umuryango w'Abibumbye yatanze ikiganiro ku "izamuka rya karuboni n'igabanuka rya karuboni" ibigo by'Abashinwa bizigamira ku kugabanya ikoreshwa ry'ingufu no kunoza imikorere, no gushyira mu bikorwa ivugurura ry'ikoranabuhanga n'ubwenge ry'ibigo. Hamwe n'iterambere rihoraho ry'ikoranabuhanga ryo gucapa no guteza imbere kurengera ibidukikije mu nganda z'icapiro mu gihe kizaza, ikoranabuhanga ryo gucapa rya UV-LED rizakomeza gukura, bizafasha inganda z'icapiro guhinduka no kuvugurura no gutera imbere cyane.
