Ziziphi iiMigaqo kunye neeMpawu zoMnyama we-Ultraviolet LED amaso esibane?

DUVLED amaso isibane " > Amaso adutyuliweyo kunye neempawu 1. Indlela yokukhanyisa yamaso esibane adityanisiweyo: Amandla ombane okuphela kweqhina le-PN enza umqobo othile onokubakho. UZi uthe saa omnye nomnye. Ngenxa yokuba izinga lokufuduka kwe-elektroniki likhulu kakhulu kunezinga lokufuduka komqolomba, inani elikhulu lokusasazwa kwe-elektroniki liya kubonakala kwindawo ye-P, kwaye inani elincinci lomthwali lenziwe kwindawo ye-P. Olu hlobo lwe-elektroniki ludityaniswe emqolombeni kwixabiso, kwaye amandla akhululwa ngendlela yamandla okukhanya. Oko kukuthi, umgaqo wokukhanya kweenwele ze-PN. Umthombo wesibane we-DUVLED wesixhobo sokunyanga isibane sesibane se-DUV somthombo wokukhanya isixhobo sokunyanga 2. Isibane sesibane seDUV esikhupha amandla: adla ngokubizwa ngokuba yi-quantum yangaphandle amandla ecandelo. Amandla e-quantum yangaphakathi yecandelo ekuqaleni amandla okuguqula i-photoelectric yecandelo ngokwalo. Okokuqala, kubandakanya iimpawu zecandelo ngokwalo (ezifana nokukwazi ukuzisa, iziphene, ukungcola, njl.), kunye nesakhiwo kunye nesakhiwo secandelo ngokwalo. Nangona kunjalo, amandla avela kwicandelo abhekisela kwifoton eyenziwe ngaphakathi kwecandelo. Emva kokufunxa, ukuchaswa, kunye nokubonakaliswa kwecandelo ngokwalo, inani leefotoni ezenziwe ngaphandle kwecandelo linokulinganiswa kumsebenzi wangempela. Ngako oko, izinto ezichaphazelayo zokususa amandla zibandakanya izinga lokuxutywa kwecandelo ngokwalo, i-geometric structure yecandelo, i-refractive index ye-refractive index yecandelo kunye necandelo lokupakisha, kunye neempawu zokuchithwa kwesakhiwo secandelo. Phakathi kwabo, amandla e-quantum yangaphakathi yimveliso yamandla okukhutshwa kwecandelo, oko kukuthi, inxalenye yonke yecandelo, oko kukuthi, amandla angaphandle e-quantum yecandelo. Ngexesha lokuqala lophuhliso lwecandelo, phucula amandla angaphakathi e-quantum. Indlela yokuqala kukuphucula umgangatho wekristale yomqobo kunye nokutshintsha ubume bomqobo, ukuze amandla ombane angabi lula ukuguqula amandla obushushu, aze aphucule ngokuthe ngqo amandla akhanyayo amaso e-ultraviolet enzulu isibane se-LED, kwaye ngoko ke ngoko Yandisa ithiyori yangaphakathi quantum amandla 70%, kodwa ngoko amandla quantum yangaphakathi phantse kufutshane umda ithiyori. Kule meko, amandla e-quantum yangaphakathi yecandelo lokuphucula ayikwazi ukunyusa ukukhanya okupheleleyo kwecandelo, ngoko ke ukukhutshwa kokuphuculwa kwecandelo eliqhubela phambili liba sisihloko sophando oluphambili. Indlela ephambili ngoku yile: tshintsha imilo yangaphandle yeenkozo —— Ulwakhiwo lwe-TIP, tshintsha uburhabaxa bomphezulu. 3. Iimpawu zombane ze-ultraviolet ezinzulu ze-LED: isixhobo solawulo lwangoku, iimpawu zomthwalo zifana ne-UI curve yeqhina le-PN, utshintsho oluncinci lwe-voltage engenayo luya kubangela utshintsho olubalulekileyo kwi-current current (inqanaba lesalathisi). Incinci, kwaye iphinde ibuyele umva i-voltage yokuqhawula. Kuya kufuneka ukhethe indlela efanelekileyo yokusetyenziswa kwangempela. Njengoko iqondo lokushisa lisanda, i-voltage yangaphambili ye-ultraviolet ye-LED ye-lamp ye-LED iyancipha, kwaye i-coefficient yeqondo lokushisa libi. Izibane ezimnyama ze-ultraviolet ze-LED zidla amandla kwaye ziguqulwa ngokuyinxenye zibe amandla okukhanya. Yile nto kanye esiyidingayo. Amandla obushushu aseleyo okunyusa ubushushu beqhina. Inokumelwa ngeekhalori (amandla) akhutshiweyo. 4. Iimpawu zamehlo ezinzulu ze-ultraviolet ze-LED izibane ze-LED: I-UV ye-UV ye-LED yesibane enzulu inika i-monochrome enesiqingatha-ububanzi. Njengoko i-gap yamandla yeesemiconductors iyancipha njengoko iqondo lobushushu lisanda, i-wavelength ephezulu ye-luminescence yayo ihambelana neqondo lokushisa kunye nobushushu. Ukwandisa ukwanda, oko kukuthi, i-spectrum ibomvu, i-coefficient yokushisa i-2 3A /. I-ultraviolet emnyama ye-LED yokukhanya kweperile L iyatshintsha kunye ne-positive yangoku. Ukwandisa yangoku, unokuqikelela ukukhanya kokukhanya; kokukhona uphezulu ubushushu be-ambient, kokukhona esezantsi amandla ayintlanganisela, kokukhona esezantsi ubushushu obukhanyayo, kwaye kokukhona esezantsi okunye ukuqaqamba okuqaqambileyo. Iimpawu ezinzulu ze-ultraviolet isibane se-bead fever: yangoku encinci, ukunyuka kobushushu akubonakali. Xa ubushushu be-ambient buphezulu, i-wavelength ephambili yamaso e-ultraviolet ekhanyayo iya kuphinda iphindwe, ukuqaqamba kuyancipha, ukukhanya okukhanyayo okufanayo kuncipha, kwaye ukungaguquguquki kuya kuba nzima. I-matrix yamachaphaza akhethekileyo kunye nokunyuka kobushushu besikrini esikhulu kunempembelelo enkulu ekuthembekeni nasekuzinzeni kwe-LED. Ngoko uyilo lokutshatyalaliswa kobushushu ngundoqo. Ubomi obunzulu besibane sesibane se-ultraviolet: Umsebenzi wexesha elide weentsimbi ezinzulu ze-ultraviolet ze-LED ziya kukhokelela ekwaluphaleni okukhanyayo, ngakumbi amaso esibane se-ultraviolet anamandla aphezulu. Xa ulinganisa ubomi beentsimbi ezinzulu ze-ultraviolet ze-LED, akwanelanga ukusebenzisa umonakalo webhalbhu njengokulahleka kobomi bobunzulu be-ultraviolet buhlalu be-LED. Umzekelo, i-35%, oku kunengqiqo ngakumbi. Amandla aphezulu Ukupakisha ukukhanya kwe-UV okukhupha i-diode: Okokuqala, qwalasela ukutshatyalaliswa kobushushu kunye nokungabikho kokukhanya. Ngokumalunga nokutshatyalaliswa kobushushu, i-radiator ye-copper-based based lining isetyenzisiweyo, kwaye emva koko ixhunywe kwi-radiator ye-aluminium. Iinkozo kunye nobushushu belayini budityanisiwe. Indlela yokutshatyalaliswa kobushushu ingcono. Ngokumalunga nokukhanya, khetha i-chip inverted izakhono, kwaye ungeze i-reflex surface ukuze ubonise ukukhanya ukonakalisa ukukhanya ukusuka ezantsi kunye necala, ukwenzela ukuba ufumane ngaphezulu kokukhanya.
