Yiziphi Izimiso Nezimpawu Zobuhlalu Besibani Se-Ultraviolet LED Emnyama?

Ubuhlalu besibani se-DUVLED " > Umgomo wobuhlalu obuhlanganisiwe nezici 1. Indlela yokukhanyisa yobuhlalu besibani obugwetshiwe: I-voltage yokugcina yefindo le-PN yakha umgoqo othile ongaba khona. Zihlakazeke zodwa. Ngenxa yokuthi izinga lokufuduka nge-elekthronikhi likhulu kakhulu kunezinga lokuthuthwa komhume, inani elikhulu lokusabalalisa nge-elekthronikhi lizovela endaweni engu-P, futhi inani elincane lomthwali liyakhiwa endaweni engu-P. Lolu hlobo lwe-electronics luhlanganiswe emhumeni ngentengo, futhi amandla akhululwa ngendlela yamandla okukhanya. Okusho ukuthi, isimiso sokukhanyisa izinwele ze-PN. I-DUVLED umugqa wesibani womthombo wokukhanya wokwelapha imishini ye-DUV yesibani somugqa wokukhanya womthombo wokukhanya wokwelapha imishini 2. Amandla okukhipha ukukhanya kwesibani se-DUV: ngokuvamile abizwa ngokuthi amandla e-quantum angaphandle engxenye. Amandla e-quantum angaphakathi engxenye ekuqaleni amandla okuguqula i-photoelectric yengxenye ngokwayo. Okokuqala, kuhilela izici zengxenye ngokwayo (njengokukwazi ukuletha, amaphutha, ukungcola, njll.), kanye nesakhiwo nokwakheka kwengxenye ngokwayo. Nokho, amandla asuka engxenyeni abhekisela ku-photon ekhiqizwe ngaphakathi kwengxenye. Ngemva kokumuncwa, ukuphindaphinda, nokuboniswa kwengxenye ngokwayo, inani lamafotoni enziwe ngaphandle kwengxenye lingalinganiswa ekusebenzeni kwangempela. Ngakho-ke, izici ezithonyayo zokukhipha amandla zihlanganisa izinga lokumuncwa kwengxenye ngokwayo, ukwakheka kwejiyomethri yengxenye, umehluko wenkomba ye-refractive yengxenye kanye nengxenye yokupakisha, nezici zokusabalalisa zesakhiwo sengxenye. Phakathi kwabo, amandla e-quantum yangaphakathi angumkhiqizo wamandla okukhipha ingxenye, okungukuthi, ingxenye yonke yengxenye, okungukuthi, amandla e-quantum yangaphandle yengxenye. Esikhathini sokuqala sokuthuthukiswa kwengxenye, thuthukisa amandla e-quantum yangaphakathi. Indlela yokuqala iwukuba ngcono izinga crystal umgoqo futhi ushintshe isakhiwo umgoqo, ukuze amandla amandla akulula ukuguqula ibe amandla ashisayo, bese ithuthukisa ngqo amandla akhanyayo ejulile ultraviolet LED ubuhlalu isibani, futhi bese-ke bese Kukhushulwa amandla e-quantum angaphakathi etiyetha angama-70%, kodwa ngakho amandla e-quantum angaphakathi acishe asondele kumkhawulo wethiyori. Kulokhu, amandla e-quantum angaphakathi engxenye yokuthuthukisa awakwazi ukukhulisa ukukhanya okuphelele kwengxenye, ngakho-ke ukukhishwa kokuthuthukiswa kwengxenye eqhubekayo kuba isihloko esiyinhloko socwaningo. Indlela eyinhloko manje: shintsha ukuma kwangaphandle kokusanhlamvu —— Isakhiwo se-TIP, shintsha ubulukhuni bobuso. 3. Izici zikagesi zesibani se-ultraviolet LED ezijulile: idivayisi yokulawula yamanje, izici zomthwalo zifana nejika le-UI lefindo le-PN, izinguquko ezincane ze-voltage engenayo zizodala izinguquko eziphawulekayo kumanje wamanje (izinga lenkomba). I-voltage encane, nehlehlayo yokuhlehla. Kufanele ukhethe indlela elungele ukusetshenziswa kwangempela. Njengoba izinga lokushisa likhuphuka, i-voltage eya phambili yobuhlalu besibani se-ultraviolet ejulile ye-ultraviolet iyancipha, futhi izinga lokushisa libi. Ubuhlalu besibani se-ultraviolet ye-LED emnyama budla amandla futhi buguqulwe kancane baba amandla okukhanya. Yilokhu kanye esikudingayo. Amandla okushisa asele okwandisa izinga lokushisa lefindo. Ingamelwa amakhalori (amandla) akhululiwe. 4. Izici zokubonwayo zobuhlalu obujulile be-ultraviolet LED isibani: Ubuhlalu besibani se-UV ejulile ye-UV buhlinzeka nge-monochrome yobubanzi obuyingxenye. Njengoba igebe lamandla lama-semiconductors lincipha njengoba izinga lokushisa likhuphuka, ubude begagasi be-luminescence bayo buhambisana nezinga lokushisa nezinga lokushisa elihambisana nezinga lokushisa. Ukwandisa ukwanda, okungukuthi, i-spectrum ibomvu, i-coefficient yokushisa i-2 3A /. Ukukhanya kwepearly kwe-ultraviolet LED okumnyama kuyashintsha kanye namandla amanje. Ukwandisa yamanje, ungakwazi ukulinganisa ukukhanya kokukhanya; ukuphakama kwezinga lokushisa kwe-ambient, amandla ayinhlanganisela ephansi, amandla okukhanya aphansi, futhi kwehla okunye ukukhanya okukhanyayo. Izici ezijulile ze-ultraviolet isibani se-bead fever: yamanje encane, ukukhuphuka kwezinga lokushisa akubonakali. Lapho izinga lokushisa lendawo liphezulu, ubude begagasi obuyinhloko bobuhlalu obukhanyayo be-ultraviolet buzoshintshashintsha, ukukhanya kunciphe, ukufana kokukhanya okukhanyayo kuncipha, futhi ukungaguquguquki kuba kubi. I-matrix yamachashazi akhethekile nokukhuphuka kwezinga lokushisa kwesikrini esikhulu kunomthelela omkhulu ekuthembekeni nasekuzinzeni kwe-LED. Ngakho idizayini yokukhipha ukushisa iwukhiye. Impilo yobuhlalu besibani se-ultraviolet ejulile ye-ultraviolet: Umsebenzi wesikhathi eside wobuhlalu besibani se-ultraviolet ejulile uzoholela ekugugeni okukhanyayo, ikakhulukazi ubuhlalu besibani se-ultraviolet LED obunamandla aphezulu. Lapho ukala ukuphila kobuhlalu obujulile be-ultraviolet LED isibani, akwanele ukusebenzisa umonakalo wesibani njengokulahlekelwa ukuphila kobuhlalu obujulile be-ultraviolet LED. Isibonelo, ama-35%, lokhu kunengqondo. Amandla aphezulu Ukupakishwa kwe-diode yokukhanya okujulile kwe-UV: Okokuqala, cabangela ukuchithwa kokushisa nokuphuma ekukhanyeni. Ngokuphathelene nokuchithwa kokushisa, i-radiator esekelwe ethusi isetshenziswa, bese ixhunywe ku-radiator ye-aluminium. Okusanhlamvu nolwelwesi olushisayo kushiselwe. Indlela yokukhipha ukushisa ingcono. Mayelana nokukhanya, khetha amakhono ahlanekezelwe we-chip, bese wengeza indawo ye-reflex ukuze ubonise ukukhanya ukuze konakalise ukukhanya kusuka phansi kanye nohlangothi, ukuze ukwazi ukuphuma okuningi ekukhanyeni.
