Nubwo imirasire ya UV ishobora guteza akaga ubuzima mubuzima bwa buri munsi, nko gutwika izuba, imirasire ya UV izatanga ingaruka nyinshi zingirakamaro mubice bitandukanye.Nkurumuri rusanzwe rugaragara LED, iterambere rya UV LED rizazana byinshi byoroshye mubikorwa byinshi bitandukanye.
Iterambere ryikoranabuhanga rigezweho ryagura ibice byisoko rya UV LED kugera kumurongo mushya wo guhanga udushya no gukora.Abashakashatsi bashushanya ko tekinoroji nshya ya UV LEDs ishobora gutanga inyungu nini, ingufu hamwe no kuzigama umwanya ugereranije nubundi buryo bwikoranabuhanga.Iyaruka rya tekinoroji ya UV LED ifite ibyiza bitanu byingenzi, niyo mpamvu isoko ryikoranabuhanga riteganijwe kwiyongera 31% mumyaka 5 iri imbere.
Imikoreshereze yagutse
Ikirangantego cy'umucyo ultraviolet kirimo uburebure bwose kuva kuri 100nm kugeza 400nm z'uburebure kandi muri rusange bigabanyijemo ibyiciro bitatu: UV-A (nanometero 315-400, bizwi kandi nka ultraviolet ndende), UV-B (nanometero 280-315, nayo bizwi nka medium wave) Ultraviolet), UV-C (nanometero 100-280, izwi kandi nka ultraviolet ngufi).
Ibikoresho by'amenyo hamwe no kumenyekanisha porogaramu byari hakiri kare gukoresha UV LEDs, ariko imikorere, igiciro ninyungu ziramba, kimwe nubuzima bwibicuruzwa byiyongera, byihuta gukoresha ikoreshwa rya UV LED.Muri iki gihe imikoreshereze ya UV LED zirimo: ibyuma bya optique n'ibikoresho (230-400nm), kwemeza UV, barcode (230-280nm), guhagarika amazi yo hejuru (240-280nm), kumenyekanisha no gutahura amazi no gusesengura (250-405nm), Isesengura rya poroteyine no kuvumbura ibiyobyabwenge (270-300nm), kuvura urumuri rw’ubuvuzi (300-320nm), gucapa polymer na wino (300-365nm), impimbano (375-395nm), kuboneza hejuru / kwisiga (390-410nm)).
Ingaruka ku bidukikije - gukoresha ingufu nke, imyanda mike kandi nta bikoresho byangiza
Ugereranije nubundi buryo bwikoranabuhanga, UV LED ifite inyungu zidukikije.Ugereranije n'amatara ya fluorescent (CCFL), LED LED ifite 70% yo gukoresha ingufu nke.Byongeye kandi, UV LED yemewe na ROHS kandi ntabwo irimo mercure, ibintu byangiza bikunze kuboneka mubuhanga bwa CCFL.
UV LEDs ni ntoya mubunini kandi iramba kuruta CCFLs.Kuberako UV LEDs zinyeganyega- kandi ntizishobora guhungabana, kumeneka ni gake, kugabanya imyanda nigiciro.
Ikongera igihe kirekire
Mu myaka icumi ishize, UV LEDs zahanganye nubuzima.Nubwo ifite inyungu nyinshi, imikoreshereze ya UV LED yagabanutse cyane kubera ko urumuri rwa UV rukunda gusenya LED ya epoxy ya LED, bikagabanya ubuzima bwa UV LED kugeza munsi yamasaha 5.000.
Igisekuru kizaza cya tekinoroji ya UV LED igaragaramo "gukomera" cyangwa "UV-irwanya" epoxy encapsulation, iyo, nubwo itanga ubuzima bwamasaha 10,000, iracyari kure bihagije kubisabwa byinshi.
Mu mezi make ashize, tekinoroji nshya yakemuye iki kibazo cyubwubatsi.Kurugero, paki ya TO-46 yuzuye ifite ibirahuri byakoreshejwe kugirango isimbuze lens epoxy, yongereye igihe cyumurimo byibuze inshuro icumi kugeza kumasaha 50.000.Hamwe niki kibazo gikomeye cyubwubatsi hamwe nibibazo bijyanye no guhagarika byimazeyo uburebure bwumurongo byakemuwe, tekinoroji ya UV LED yahindutse uburyo bushimishije kubwinshi bwimikorere.
Pimikorere
UV LEDs nayo itanga inyungu zingenzi kurenza ubundi buryo bwikoranabuhanga.UV LEDs itanga inguni ntoya hamwe nigiti kimwe.Bitewe nubushobozi buke bwa UV LEDs, abajenjeri benshi bashushanya bashaka urumuri rugaragaza imbaraga zisohoka mukarere runaka.Hamwe n'amatara asanzwe ya UV, injeniyeri agomba gushingira kumikoreshereze yumucyo uhagije kugirango amurikire agace kamwe kandi gahuzagurika.Kuri UV LEDs, ibikorwa bya lens byemerera imbaraga nyinshi zisohoka za UV LED kwibanda aho bikenewe, bigatuma impande zombi zangiza.
Guhuza iyi mikorere, ubundi buryo bwikoranabuhanga busaba gukoresha izindi lens, wongeyeho igiciro cyinyongera nibisabwa umwanya.Kuberako UV LED idasaba izindi lens kugira ngo igere ku mfuruka zifatika hamwe n’ibiti bimwe, gukoresha ingufu nke no kongera igihe kirekire, UV LED igura kimwe cya kabiri cyo gukoresha ugereranije n’ikoranabuhanga rya CCFL.
Ibiciro byigiciro byihariwe byubaka UV LED igisubizo kubisabwa runaka cyangwa gukoresha ikoranabuhanga risanzwe, iyambere akenshi iba ingirakamaro mubijyanye nigiciro nigikorwa.UV LEDs ikoreshwa mumirongo myinshi, kandi guhuza imiterere nuburemere bwimbaraga murwego rwingenzi.Niba umutanga umwe atanga umurongo wuzuye ukenewe kugirango usabe porogaramu runaka, fagitire y'ibikoresho iragabanuka, umubare w'abatanga ibicuruzwa uragabanuka, kandi umurongo urashobora kugenzurwa mbere yo koherezwa kuri injeniyeri.Muri ubu buryo, ibikorwa bike birashobora kuzigama ibiciro byubwubatsi namasoko kandi bigatanga ibisubizo byiza bijyanye nibisabwa-kurangiza.
Witondere gushaka uwaguha isoko ushobora gutanga ibisubizo byigiciro cyigiciro cyihariye kandi ashobora gutegura ibisubizo byumwihariko kubyo ukeneye gusaba.Kurugero, utanga isoko afite uburambe bwimyaka icumi mugushushanya kwa PCB, optique yihariye, gushakisha imishwarara no kubumba azashobora gutanga amahitamo atandukanye kubisubizo bihendutse kandi byihariye.
Mu gusoza, iterambere ryikoranabuhanga rigezweho muri UV LEDs ryakemuye ikibazo cyo guhagarara neza kandi byongereye igihe cyo kubaho kugeza kumasaha 50.000.Bitewe nibyiza byinshi bya UV LED nko kongera igihe kirekire, nta bikoresho bishobora guteza akaga, gukoresha ingufu nke, ingano ntoya, imikorere isumba iyindi, kuzigama amafaranga, uburyo bwo gukoresha ibicuruzwa neza, nibindi, tekinoroji igenda yiyongera kumasoko, inganda nibindi byinshi ikoresha uburyo bushimishije.
Mu mezi n'imyaka iri imbere, hazakomeza kubaho iterambere, cyane cyane muri gahunda yo gukora neza.Gukoresha UV LEDs bizakura byihuse.
Ikibazo gikomeye gikurikira kuri tekinoroji ya UV LED ni imikorere.Kubisabwa byinshi ukoresheje uburebure buri munsi ya 365nm, nka Phototherapie yubuvuzi, kwanduza amazi no kuvura polymer, imbaraga zisohoka za UV LEDs ni 5% -8% byimbaraga zinjiza.Iyo uburebure bwa 385nm no hejuru, imikorere ya UV LED iriyongera, ariko kandi 15% byimbaraga zinjiza.Mugihe tekinoroji igenda ikomeza gukemura ibibazo byimikorere, porogaramu nyinshi zizatangira gukoresha tekinoroji ya UV LED.
