Nangona imitha ye-UV inokuba yingozi kwizinto eziphilayo kubomi bemihla ngemihla, njengokutshiswa lilanga, imitha ye-UV iya kubonelela ngemiphumo emihle kwiinkalo ezahlukeneyo.Njengee-LED zokukhanya ezibonakalayo eziqhelekileyo, uphuhliso lwe-UV LEDs luya kuzisa lula ngakumbi kwizicelo ezininzi ezahlukeneyo.
Uphuhliso lwamva nje lwetekhnoloji lwandisa iindawo zemakethi ye-UV ye-LED ukuya kwiindawo eziphakamileyo zokuyila imveliso kunye nokusebenza.Iinjineli zoyilo ziqaphela ukuba itekhnoloji entsha yee-UV LEDs inokuvelisa inzuzo enkulu, amandla kunye nokonga indawo xa kuthelekiswa nobunye ubugcisa.I-teknoloji ye-UV ye-LED yesizukulwana esilandelayo ineenzuzo ezintlanu ezibalulekileyo, yiyo loo nto imarike yale teknoloji kulindeleke ukuba ikhule nge-31% kwiminyaka emi-5 ezayo.
Uluhlu olubanzi losetyenziso
I-spectrum yokukhanya kwe-ultraviolet iqulethe onke amaza amaza ukusuka kwi-100nm ukuya kwi-400nm ubude kwaye yahlulahlulwe ngokubanzi ngokweendidi ezintathu: UV-A (315-400 nanometers, ekwaziwa ngokuba yi-ultraviolet-wave ultraviolet), UV-B (280-315 nanometers, nayo eyaziwa ngokuba liza eliphakathi) Ultraviolet), UV-C (100-280 nanometers, eyaziwa ngokuba short-wave ultraviolet).
Izixhobo zamazinyo kunye nezicelo zokuchongwa yayizizicelo zokuqala zee-UV ze-UV, kodwa ukusebenza, iindleko kunye nezibonelelo ezihlala ixesha elide, kunye nokwandisa ubomi bemveliso, kwandisa ngokukhawuleza ukusetyenziswa kwee-UV LEDs.Ukusetyenziswa kwangoku kwee-LED ze-UV zibandakanya: i-optical sensors kunye nezixhobo (230-400nm), ukuqinisekiswa kwe-UV, i-barcodes (230-280nm), ukutshatyalaliswa kwamanzi angaphezulu (240-280nm), ukuchongwa kunye nokufumanisa ulwelo lomzimba kunye nohlalutyo (250-405nm), Uhlalutyo lweprotheyini kunye nokufunyanwa kweziyobisi (270-300nm), unyango lokukhanya kwezonyango (300-320nm), i-polymer kunye ne-inki yokuprinta (300-365nm), inkohliso (375-395nm), inzalo yomhlaba / inzalo yokuthambisa (390-410nm) ).
Impembelelo yokusingqongileyo - ukusetyenziswa kwamandla aphantsi, inkunkuma encinci kwaye akukho zixhobo ezinobungozi
Xa kuthelekiswa nobunye ubuchwephesha, ii-UV LED zinezibonelelo ezicacileyo zokusingqongileyo.Xa kuthelekiswa nezibane ze-fluorescent (CCFL), ii-LED ze-UV zine-70% yokusetyenziswa kwamandla aphantsi.Ukongeza, i-UV LED iqinisekisiwe nge-ROHS kwaye ayinayo i-mercury, into enobungozi efumaneka kwitekhnoloji yeCCFL.
Ii-LED ze-UV zincinci ngobukhulu kwaye zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona.Ngenxa yokuba ii-LED ze-UV zingcangcazela- kwaye ziyakwazi ukumelana nomothuko, ukwaphuka kunqabile, kunciphisa inkcitho kunye nenkcitho.
Iukwandisa ubomi obude
Kwiminyaka elishumi edlulileyo, ii-LED ze-UV ziye zacelwa umngeni malunga nobomi.Ngaphandle kwezibonelelo zayo ezininzi, ukusetyenziswa kwe-UV ye-UV yehle kakhulu kuba umqa we-UV uthande ukophula i-epoxy resin ye-LED, ukunciphisa ubomi be-UV LED ukuya ngaphantsi kweeyure ezingama-5,000.
Isizukulwana esilandelayo sobuchwephesha be-UV LED sibonisa "i-hardened" okanye "UV-resistant" epoxy encapsulation, leyo, ngelixa inikezela ubomi beeyure ze-10,000, isekude ngokwaneleyo kwizicelo ezininzi.
Kwezi nyanga zimbalwa zidlulileyo, itekhnoloji entsha iwusombulule lo mngeni wobunjineli.Ngokomzekelo, i-TO-46 ipakethe enqabileyo ene-glass lens yayisetyenziselwa ukubuyisela i-epoxy lens, eyandisa ubomi bayo benkonzo ubuncinane ngamaxesha alishumi ukuya kwiiyure ezingama-50,000.Ngalo mceli mngeni mkhulu wobunjineli kunye nemiba enxulumene nokuzinziswa ngokupheleleyo kobude be-wavelength esonjululwe, itekhnoloji ye-UV ye-LED ibe lukhetho olunomtsalane kwinani elikhulayo lezicelo.
Pukusebenza
Ii-LED ze-UV zikwabonelela ngeenzuzo ezibalulekileyo zokusebenza ngaphezu kobunye ubuchwephesha.Ii-LED ze-UV zibonelela nge-angle encinci ye-boam kunye ne-uniform beam.Ngenxa yokusebenza okuphantsi kwee-LED ze-UV, uninzi lweenjineli zoyilo zijonge i-angle ye-beam eyandisa amandla emveliso kwindawo ethile ekujoliswe kuyo.Ngezibane eziqhelekileyo ze-UV, iinjineli kufuneka zithembele ekusebenziseni ukukhanya okwaneleyo ukukhanyisa indawo ukuze ifane kunye nokubumbana.Kwii-LED ze-UV, isenzo se-lens sivumela uninzi lwamandla aphumayo e-UV LED ukuba agxininiswe apho afuneka khona, okuvumela i-angle yokukhupha engqongqo.
Ukuhambelana nalo msebenzi, obunye ubuchwephesha buya kufuna ukusetyenziswa kwezinye iilensi, kongezwe iindleko ezongezelelweyo kunye neemfuno zendawo.Ngenxa yokuba ii-LED ze-UV azifuni iilensi ezongezelelweyo ukufezekisa ii-angles ze-beam eziqinileyo kunye neepateni ezifanayo ze-beam, ukusetyenziswa kwamandla aphantsi kunye nokuqina okongeziweyo, ii-LED ze-UV zibiza isiqingatha sokusebenzisa xa kuthelekiswa nobuchwepheshe beCCFL.
Iinketho ezinikezelweyo eziziindleko ezizinikezeleyo zakha isisombululo se-UV ye-UV kwisicelo esithile okanye ukusebenzisa itekhnoloji esemgangathweni, yangaphambili isoloko isebenziseka ngakumbi ngokweendleko kunye nokusebenza.Ii-LED ze-UV zisetyenziswa kwii-arrays kwiimeko ezininzi, kwaye ukuhambelana kwepateni ye-beam kunye nokuqina kulo lonke uluhlu kubalulekile.Ukuba umboneleli omnye unikezela lonke uluhlu oludibeneyo olufunekayo kwisicelo esithile, i-bill ye-bill yezinto eziphathekayo iyancitshiswa, inani lababoneleli liyancitshiswa, kwaye uluhlu lunokuhlolwa ngaphambi kokuthunyelwa kwinjineli yokuyila.Ngale ndlela, ukuthengiselana okumbalwa kunokugcina iindleko zobunjineli kunye nokuthengwa kwempahla kunye nokubonelela ngezisombululo ezisebenzayo ezilungiselelwe iimfuno zokuphela kwesicelo.
Qinisekisa ukuba ufumana umthengisi onokubonelela ngezisombululo zesiko ezibiza iindleko kwaye unokuyila izisombululo ngokukodwa kwiimfuno zakho zesicelo.Ngokomzekelo, umthengisi onamava eminyaka elishumi kwi-PCB design, i-optics yesiko, ukulandelwa kwe-ray kunye nokubumba kuya kukwazi ukunika uluhlu lweendlela zokukhetha ezona zisombululo ezingabizi kakhulu kunye nezikhethekileyo.
Ukuqukumbela, uphuculo lwamva nje lwetekhnoloji kwii-UV ze-UV luyisombulule ingxaki yozinzo olupheleleyo kwaye bandisa kakhulu ubomi babo kwiiyure ezingama-50,000.Ngenxa yeenzuzo ezininzi zee-UV ze-UV ezinjengokuqina okongeziweyo, akukho zixhobo ziyingozi, ukusetyenziswa kwamandla aphantsi, ubungakanani obuncinci, ukusebenza okuphezulu, ukonga iindleko, ukhetho olunexabiso eliphantsi, njl. isebenzisa Inketho enomtsalane.
Kwiinyanga nakwiminyaka ezayo, kuya kubakho uphuculo olungakumbi, ngakumbi kwiprogram esebenzayo.Ukusetyenziswa kwe-UV LEDs kuya kukhula ngokukhawuleza.
Umceli mngeni omkhulu olandelayo kwitekhnoloji ye-UV ye-LED kukusebenza kakuhle.Kwizicelo ezininzi ezisebenzisa amaza amaza angaphantsi kwe-365nm, ezifana ne-phototherapy yonyango, i-disinfection yamanzi kunye ne-polymer therapy, amandla aphumayo e-UV LEDs kuphela i-5% -8% yamandla okufaka.Xa ubude be-waveleng yi-385nm nangaphezulu, ukusebenza kakuhle kwe-UV LED kuyanda, kodwa kunye ne-15% kuphela yamandla okufaka.Njengoko ubugcisa obuvelayo buqhubeka nokujongana nemiba esebenzayo, izicelo ezininzi ziya kuqala ukwamkela iteknoloji ye-UV LED.
