340-350nm UVB LEDs - Izinganekwane vs. Amaqiniso

Kube nezingxoxo eziningi phakathi kososayensi nomphakathi jikelele mayelana nemisebe ye-ultraviolet B (UVB), ikakhulukazi esifundeni esingu-340-350 nm. Kube nokukhathazeka ngokuphepha kanye nemiphumela yezempilo engase ibe khona yama-ultraviolet B light-emitting diode (LED) naphezu kokusetshenziswa kwawo kabanzi ezindaweni ezihlanganisa ukwelashwa, ukuhlanzwa kwamanzi, nokuthuthukiswa kwezolimo. Ukucacisa ukudideka nokukhanyisa izingozi nezinzuzo zokusebenzisa 340 nm LED - I-LED engu-350nm (UVB), lesi sihloko sizonikeza isifinyezo esiphelele esisekelwa idatha yesayensi futhi sizame ukuphikisa imibono eyiphutha mayelana nokuphepha kwabo.

Ulwazi olusabalele lwemiphumela yemisebe ye-ultraviolet (UV) ezicutshini eziphilayo kuwumthombo oyinhloko wengxabano ezungezile. Ama-LED we-UVB . Izinkinga eziningi zempilo, ezihlanganisa umdlavuza wesikhumba, ukuguga ngaphambi kwesikhathi, nokukhubazeka kwamehlo, kungase kubangelwe ukuchayeka isikhathi eside emisebeni ye-ultraviolet. Nokho, inkolelo eyandile yokuthi imisebe ye-UV iyingozi ngokwemvelo ibuzwa ngokusetshenziswa kwe-  ama-diode akhipha ukukhanya kwe-ultraviolet-B  kuzilungiselelo ezilawulwa ngokucophelela kanye nezinhlelo zokusebenza ezihlosiwe. Ukuhlinzeka ngesisekelo esiqinile sokuhlaziywa okuningiliziwe kwephrofayili yokuphepha ye UV LED 340 nm, i-UV LED 350nm , lesi sigaba sizoqhathanisa i-spectra yabo ekhiphayo namandla naleyo yokukhanya kwelanga okungokwemvelo kanye nemithombo ye-UV evamile.

Inganekwane 1: 340nm-350nm Imisebe ye-UVB Iyingozi

Ukungaqondi kahle okuvamile ukuthi ubungozi bezempilo obulethwa imithombo ehlukene namaza wamaza okukhanya kwe-UVB kuyalingana. Le nganekwane iyaqhubeka ngokunganaki kwayo iqiniso lokuthi amaza e-UV ahlukene anemiphumela ehluke kakhulu yezinto eziphilayo. Ngokwesibonelo, i 340 nm UVB LED- 350nm UVB LED igcwalisa isidingo esiyingqayizivele ngoba ingase ibe usizo kweminye imisebenzi ngaphandle kokubeka ingozi efanayo namanye amabhendi e-UVB.

Ukukhiqizwa kukavithamini D esikhumbeni kuyindlela ebalulekile yokusebenza komzimba nempilo yamathambo, futhi ucwaningo lubonisa ukuthi ukukhanya kwe-UVB ebangeni le-340nm led-350nm led kungase kusetshenziselwe le njongo. Uma isetshenziswe ngendlela efanele, i-spectrum engu-340-350 nm yemisebe ye-ultraviolet B inikeza indawo ejabulisayo phakathi kokulimala kwe-DNA nobungozi bomdlavuza, ngokungafani namaza amaza e-UVB amafushane. Qonda ukuthi ingozi exhunywe nama-LED e-UVB incike kakhulu ekushubeni, ubude besikhathi, nomongo wokuchayeka.

Izivumelwano eziqinile ziphoqa ukusetshenziswa kwe  I-ultraviolet B ekhipha ukukhanya ezilungiselelweni zezokwelapha nezokwelashwa ekwelapheni i-eczema, vitiligo, ne-psoriasis. Lezi zisebenzisa izinto ezinhle ze UV LED 340nm , I-UV LED 350nm kuyilapho ukhawulela izinto ezimbi ngegiya lokuzivikela kanye nokuchayeka okunesikhathi. Ukuphumelela kwalezi zindlela zokwelapha kubeka kungabaza inkolelo evamile yokuthi i-UVB iyingozi ngokuyisisekelo futhi igcizelela ukubaluleka kokuhlukanisa phakathi kwamaza wamaza nokusetshenziswa kwawo ngokulandelana kwawo.

Ukuthuthukiswa kobuchwepheshe be-LED kwenze kwaba nokwenzeka ukulawula ngokunembile ubude bamaza okukhanya okukhishwayo, kukhawulelwe ukuchayeka ngengozi kububanzi be-UV obuyingozi kakhulu; nokho, umbono oyiphutha usaqhubeka wokuthi yonke imisebe ye-UVB ilimaza ngokufanayo. Imithetho yezempilo yamanje isungula imikhawulo eyamukelekayo yokuqina kwemisebe kanye nobude bokuchayeka, ekhawulelwe ku-UVB yesimanjemanje. ama-diode akhipha ukukhanya . Lawa ma-LED akhiwe kucatshangelwa ukuphepha.

Idatha yesayensi nezeluleko zobungcweti, hhayi ama-phobias asabalele mayelana nemisebe ye-UV, kufanele kuthenjelwe kukho ukuze kuqedwe lobu buxoki. Ukuqaphela izinzuzo nezingozi ezingaba khona zama-UVB LED, ukukhuthaza ukusetshenziswa okufundile, nokusebenzisa izinyathelo zokuvimbela ukuze kuncishiswe noma yimiphi imiphumela engathandeki konke kuyadingeka ngenxa yemvelo ecashile yemithelela yawo.

Inganekwane 2:  I-LED engu-340-350nm  Imbangela Umdlavuza Wesikhumba

Umqondo wokuthi 340 nm LED I-LED engu-350nm ukuchayeka kudala ukulimala kwesikhumba osheshayo futhi umdlavuza wesikhumba amanga ajwayelekile. Nakuba kuyiqiniso kumaza wamaza athile kanye namaleveli okuchayeka, ukwesaba okujwayelekile kwemiphumela elimazayo yemisebe ye-UV kumela kabi ukuchayeka kwe-UVB LED.

Lapho iphathwa kahle, 340 nm I-UVB LED-350nm I-UVB LED ingase isetshenziselwe ukwelashwa okunengozi encane ngenxa yokunqunywa kokucaciswa kwe-UV spectrum. Ukuchayeka okulawulwayo kuma-LED e-UVB kulolu hlu kudala ukuhlanganiswa kwevithamini D ngokulimala okuncane kwe-DNA kunamaza amaza amafushane we-UV, axhumene kakhulu nomdlavuza wesikhumba. Ubude bokuchayeka okulawulwayo nokuqina, kanye nezinyathelo zokuvimbela ezifana nezimboni noma zokuvikela iso nokuvikela isikhumba, kunciphisa ubungozi.

Ucwaningo olwengeziwe lomtholampilo lubonise ukuthi ukukhanya kwe-UVB kumaza amaza athile kanye imithamo kungase kwelaphe ukuphazamiseka kwesikhumba okuhlanganisa i-psoriasis, ngaphandle kokunyusa ingozi yomdlavuza wesikhumba. Le miphumela ikhombisa lokho  UVB l ama-diode akhipha ukukhanya  ziphephile futhi ziwusizo ngaphansi kokugadwa kochwepheshe. Khumbula ukuthi ukuphepha kuncike emithethweni ekhawulela ukuchayeka kanye nokuqina emazingeni angalimazi amaseli.

Uhlobo lwesikhumba, ukuthambekela kofuzo, kanye nokuvezwa kwe-UV okwenyukayo ngokuhamba kwesikhathi ezinye zezinto ezithinta ukusabela komzimba emisebeni ye-UV. Ezimweni ezilawulwayo, ingozi yokulimala kwesikhumba kanye nomdlavuza ovela kuma-UVB LED iphansi kakhulu kunokuchayeka elangeni okungalawuleki, okungase kushintshe kakhulu ngamandla. Ihlanganisa i-spectrum ephelele yemisebe ye-UV.

Inganekwane 3: 340-350nm I-UVB LED Exposure Akuphephile Emehlweni

Ingozi engaba khona yama-LEDs e-UVB empilweni yamehlo ingenye ukukhathazeka okuvame kakhulu. Abanye abantu besaba ukuthi ngisho nokuchayeka isikhathi esifushane kungase kubangele ukulimala kwamehlo. Nakuba i-photokeratitis ne-cataract kuyizinkinga zangempela zamehlo ezibangelwa imisebe ye-ultraviolet, ingozi ebangelwa 340nm UV LED -350nm UV LED i s ngokuvamile ihaba.

Ukuqina nobude begagasi bokuchayeka kwe-UVB LED kungase kuthinte kakhulu ingozi yokulimala kweso. Ukukhanya kwelanga ne-UVC, ezinobude obufushane bamaza, kuyingozi kakhulu emehlweni kune-UV LED 340nm-UV LED 350nm ububanzi. Ukunciphisa kakhulu ingcuphe yokuchayeka kweso emazingeni ayingozi, izingubo zamehlo ezivikelayo kuwumkhuba ojwayelekile kuzilungiselelo zochwepheshe nezokwelashwa ezisetshenziswa njalo.  UVB l ama-diode akhipha ukukhanya .

Ngaphezu kwalokho, izibani zamanje ze-UVB LED zinezivikelo ezakhelwe ngaphakathi ezinciphisa inani lesikhathi namandla abasebenzisi abachayeka kukho kumaleveli aphephile wamehlo. Lawa madivayisi ngokuvamile ahlanganisa izihlungi nokuvikela ukuze unciphise ingozi futhi ugweme ukuvezwa okungahlosiwe ngenkathi usebenza.

Thola Isixazululo Sakho se-LED!

I-Tianhui Electronic ibihamba phambili ngokuphathelene namaphakeji e-UVB LED, enikeza uchungechunge oluphelele lokukhiqiza lwekhwalithi ethembekile namazinga athengekayo.
