1. Yintoni UV?

Okokuqala, makhe sihlolisise ingcamango ye-UV. I-UV, okt i-ultraviolet, i-ultraviolet, iliza lombane lombane elinobude obuphakathi kwe-10 nm kunye ne-400 nm. I-UV kumaqela ahlukeneyo inokwahlulwa ibe yi-UVA, UVB kunye ne-UVC.

I-UVA: kunye nobude obude obususela kwi-320-400nm, inokungena kumafu kunye neglasi kwigumbi kunye nemoto, ingene kwi-dermis yesikhumba kwaye ibangele ukutshisa. I-UVA inokwahlulwa ibe yi-uva-2 (320-340nm) kunye ne-UVA-1 (340-400nm).

I-UVB: i-wavelength iphakathi, kwaye i-wavelength iphakathi kwe-280-320nm. Iya kufunxwa yi<em>ozone layer, ibangele ukutshiswa lilanga, ukubomvu kolusu, ukudumba, ubushushu neentlungu, kunye namadyunguza okanye ukuxobuka kwiimeko ezinzima.

I-UVC: ubude bamaza buphakathi kwe-100-280nm, kodwa i-wavelength engaphantsi kwe-200nm yi-vacuum ultraviolet, ngoko inokufunxwa ngumoya. Ke ngoko, ubude bobude apho i-UVC inokuwela khona umoya buphakathi kwe-200-280nm. Okukhona ubude bawo bufutshane, kokukhona buyingozi ngakumbi. Nangona kunjalo, inokuthi ivalwe yi-ozone layer, kwaye isixa esincinci siya kufikelela kumphezulu womhlaba.

2. Umgaqo wokuvalwa kwe-UV?

IUV inokonakalisa iDNA (deoxyribonucleic acid) okanye iRNA (ribonucleic acid) yemolekyuli yemicroorganisms, ukuze iintsholongwane zife okanye zingakwazi ukuzala, ukuze kuphunyezwe injongo yokuvala inzala.

3. Ibhendi yokuvala inzala yeUV?

Ngokutsho kweInternational ultraviolet Association, “iultraviolet spectrum (indawo 'yokwenza inzala') ebaluleke kakhulu ekubulaweni kweentsholongwane emanzini nomoya luluhlu olufunxwa yiDNA (RNA kwezinye iintsholongwane). Eli candelo lokuvala inzala limalunga ne-200-300 nm”. Kuyaziwa ukuba ubude bokuvala inzala budlulela ngaphezulu kwe-280nm, kwaye ngoku bujongwa njengendawo yokwandisa ukuya kuma-300nm. Nangona kunjalo, oku kunokutshintsha kwakhona ngophando oluninzi. Izazinzulu zibonakalise ukuba ukukhanya kwe-ultraviolet okunamaza obude phakathi kwe-280nm kunye ne-300nm nako kungasetyenziselwa ukuvalwa inzala.

4. Ngobuphi obona bude bufanelekileyo bokuvala inzala?

Kukho ukungaqondi kakuhle ukuba i-254 nm yeyona ndawo ingcono yokuvala inzala, kuba i-wavelength ephezulu yesibane se-mercury soxinzelelo oluphantsi (enqunywe kuphela yi-physics yesibane) yi-253.7 nm. Enyanisweni, njengoko kuchazwe ngasentla, uluhlu oluthile lwamaza lunempembelelo ye-bactericidal. Nangona kunjalo, ngokuqhelekileyo kuqwalaselwa ukuba ubude be-265nm bobona bugqwesileyo, kuba obu bubudenge buyincopho ye-DNA yokufunxa ijika. Ke ngoko, i-UVC lelona qela lifanelekileyo lokuvala inzala.

5. Kutheni imbali ikhethe i-UVCI-LED?

Ngokwembali, isibane semercury yayikuphela kokhetho lokuvalwa kwe-UV. Nangona kunjalo, i-miniaturization yeUVC LEDamacandelo azisa intelekelelo ngakumbi kwindawo yesicelo, uninzi lwazo olungenakuqondwa ngezibane zemekyuri zemveli. Ukongeza, i-UVC led nayo ineenzuzo ezininzi, ezinjengokuqalisa ngokukhawuleza, amaxesha avumelekileyo okutshintsha, unikezelo lwamandla ebhetri akhoyo njalo njalo.

6. Imeko yesicelo se-UVC ye-LED?

Ukuvalwa komphezulu: iindawo zonxibelelwano zikawonke-wonke ezinamaza amaninzi ezifana nezixhobo zonyango, izinto zoomama nosana, indlu yangasese ekrelekrele, ifriji, ikhabhathi yetafile, ibhokisi yokugcina entsha, inkonkxa yenkunkuma ekrelekrele, ikomityi ye-thermos, i-escalator handrail kunye neqhosha lomatshini wokuthengisa amatikiti;

Ukuvala inzala kumanzi: itanki yamanzi yesithambiso samanzi, isifuma kunye nomenzi womkhenkce;

Ukuvala inzalo yamanzi aqukuqelayo: imodyuli yokucoca amanzi aqukuqelayo, i-dispenser yamanzi okusela ngokuthe ngqo;

Ukucoca umoya: isicoci somoya, isicondisi-moya.

7. Indlela yokukhetha UVC LED?

Inokukhethwa kwiiparameters ezifana namandla optical, i-peak wavelength, ubomi benkonzo, i-angle yokuphuma kunye nokunye.

Amandla okukhanya: UVC LED optical power ekhoyo kwimarike yangoku isukela kwi-2MW, 10 MW ukuya kwi-100 MW. Izicelo ezahlukeneyo zineemfuno zamandla ezahlukeneyo. Ngokubanzi, amandla okukhanya anokudityaniswa ngokudibanisa umgama wokukhanya, imfuno eguqukayo okanye imfuno engatshintshiyo. Okukhona umkhulu umgama wokukhanya, kokukhona imfuno eguqukayo, kunye namandla okukhanya afunekayo.

Incopho yobude bobude: njengoko kukhankanyiwe ngasentla, i-265nm lolona bude bugqwesileyo bokuvala inzala, kodwa ngokuqwalasela ukuba kukho umahluko omncinane kwixabiso elilinganiselweyo lencopho yamaza phakathi kwabavelisi, enyanisweni, amandla okukhanya sesona salathiso sibalulekileyo sokulinganisa impumelelo yokuvala inzala.

Ubomi benkonzo: qwalasela imfuno yobomi benkonzo ngokwexesha lenkonzo yezicelo ezithile, kwaye ufumane eyona nto ifanelekileyo ye-UVC ekhokelwayo, eyona nto ibhetele.

I-engile yemveliso yokukhanya: i-engile yemveliso yokukhanya yamaso wesibane afakwe kwi-lens yendiza idla ngokuba phakathi kwe-120-140 °, kunye ne-engile yemveliso yokukhanya ehlanganiswe ne-lens engqukuva ilungelelaniswa phakathi kwe-60-140 °. Ngapha koko, nokuba ingakanani i-angle yokuphuma kwe-UVC ye-LED ekhethiweyo, ii-LED ezaneleyo zinokuyilwa ukuba zigqume ngokupheleleyo indawo efunekayo yokuvala inzala. Kwindawo yescenelo ayinaluvelwano kuluhlu lokuvala inzala, i-engile yokukhanya encinci inokwenza ukukhanya kugxile ngakumbi, ngoko ke ixesha lokuvala inzala lifutshane.
