Dab tsi yog cov ntsiab lus thiab cov yam ntxwv ntawm Tsaus Ultraviolet LED Teeb hlaws?

DUVLED teeb hlaws " > Duvled hlaws txoj hauv kev thiab cov yam ntxwv 1. Lub teeb pom kev zoo ntawm duvled teeb hlaws dai: Qhov kawg voltage ntawm PN knot tsim ib qho kev cuam tshuam. Ziag no nyias mus nyias. Vim tias qhov hluav taws xob tsiv teb tsaws chaw nyob deb ntau dua li qhov kev hloov pauv ntawm lub qhov tsua, cov khoom siv hluav taws xob ntau yuav tshwm sim hauv thaj tsam P, thiab cov neeg nqa khoom me me yog tsim nyob rau hauv cheeb tsam P. Hom hluav taws xob no yog sib xyaw ua ke ntawm lub qhov tsua ntawm tus nqi, thiab lub zog tawm los ntawm txoj kev ntawm lub teeb lub zog. Ntawd yog, lub hauv paus ntsiab lus ntawm PN plaub hau teeb pom kev zoo. DUVLED teeb kab teeb pom kev kho cov cuab yeej DUV teeb hlaws kab teeb pom kev kho khoom siv 2. DUV teeb hlaws lub teeb emitting zog: feem ntau hu ua sab nraud quantum zog ntawm cov khoom. Internal quantum zog ntawm cov khoom yog Ameslikas lub photoelectric hloov dua siab tshiab zog ntawm cov khoom nws tus kheej. Ua ntej tshaj plaws, nws suav nrog cov yam ntxwv ntawm nws tus kheej (xws li muaj peev xwm nqa tau, tsis xws luag, impurities, thiab lwm yam), thiab cov qauv thiab cov qauv ntawm cov khoom siv nws tus kheej. Txawm li cas los xij, lub zog los ntawm cov khoom siv yog hais txog cov photon generated hauv cov khoom. Tom qab kev nqus, refraction, thiab kev xav ntawm nws tus kheej, tus naj npawb ntawm photons ua sab nraum cov khoom tuaj yeem ntsuas hauv kev ua haujlwm tiag tiag. Yog li ntawd, qhov cuam tshuam ntawm kev tshem tawm lub zog muaj xws li qhov nqus ntawm cov khoom siv nws tus kheej, cov qauv geometric ntawm cov khoom, qhov sib txawv ntawm qhov sib txawv ntawm cov khoom thiab cov ntim khoom, thiab cov yam ntxwv ntawm cov khoom siv. Ntawm lawv, lub zog quantum sab hauv yog cov khoom lag luam ntawm cov khoom siv lub zog tshem tawm, uas yog, tag nrho ntawm cov khoom siv, uas yog, lub zog quantum sab nraud ntawm cov khoom siv. Nyob rau hauv thaum ntxov lub sij hawm ntawm kev txhim kho tivthaiv, txhim kho lub internal quantum zog. Thawj txoj kev yog los txhim kho qhov zoo ntawm cov khoom siv lead ua barrier thiab hloov cov qauv ntawm lub barrier, kom lub zog lub zog tsis yooj yim rau hloov mus rau thermal zog, thiab tom qab ntawd ncaj qha txhim kho lub zog luminous ntawm qhov sib sib zog nqus ultraviolet LED teeb hlaws, thiab ces tom qab ntawd ces nce qhov theoretical internal quantum zog ntawm 70%, tab sis yog li internal quantum zog yuav luag ze rau theoretical txwv. Nyob rau hauv cov ntaub ntawv no, lub internal quantum hwj chim ntawm kev txhim kho tivthaiv tsis tuaj yeem ua rau kom tag nrho lub teeb ntawm cov tivthaiv, yog li ntawd lub extraction ntawm kev txhim kho ntawm kev loj hlob tivthaiv yog lub ntsiab lus tshawb fawb. Txoj kev tseem ceeb tam sim no yog: hloov cov duab sab nraud ntawm cov nplej —— TIP qauv, hloov qhov roughness ntawm qhov chaw. 3. Sib sib zog nqus ultraviolet LED teeb hlaws hluav taws xob cov yam ntxwv: cov cuab yeej tswj tam sim no, cov yam ntxwv ntawm kev thauj khoom zoo ib yam li UI nkhaus ntawm PN knot, qhov kev hloov pauv tsawg kawg ntawm cov inflow voltage yuav ua rau muaj kev hloov pauv tseem ceeb hauv pem hauv ntej tam sim no (qib ntsuas). Me me, thiab thim rov qab tawg voltage. Koj yuav tsum xaiv txoj kev uas haum rau kev siv tiag tiag. Raws li qhov kub thiab txias, qhov hluav taws xob rau pem hauv ntej ntawm qhov sib sib zog nqus ultraviolet LED teeb hlaws txo qis, thiab qhov kub coefficient tsis zoo. Tsaus ultraviolet LED teeb hlaws siv hluav taws xob thiab qee qhov hloov mus rau lub teeb lub zog. Qhov no yog qhov peb xav tau. Qhov seem cua sov lub zog los ua kom cov pob txha kub. tuaj yeem sawv cev los ntawm calories (lub zog) tso tawm. 4. Cov yam ntxwv kho qhov muag ntawm tob ultraviolet LED teeb hlaws: Sib sib zog nqus UV LED teeb hlaws muab ib nrab-dav monochrome. Raws li lub zog sib txawv ntawm semiconductors txo qis thaum qhov kub nce, lub ncov wavelength ntawm nws cov luminescence yog nrog qhov kub thiab txias nrog qhov kub thiab txias. Kev nce ntxiv, uas yog, spectrum yog liab, qhov kub thiab txias coefficient yog 2 3A / . Tsaus ultraviolet LED pearly brightness L hloov nrog qhov zoo tam sim no. Ua kom qhov tam sim no, koj tuaj yeem kwv yees lub teeb ci; qhov siab dua qhov ambient kub, qhov qis dua lub zog sib xyaw, qhov qis dua qhov kev siv lub teeb ci, thiab qhov qis dua lwm qhov luminous brightness. Sib sib zog nqus ultraviolet LED teeb hlaws kub taub hau yam ntxwv: me me tam sim no, qhov kub thiab txias tsis pom tseeb. Thaum lub ambient kub siab, lub ntsiab wavelength ntawm lub sib sib zog nqus ultraviolet luminous hlaws yuav redize, lub brightness txo, lub teeb luminous uniformity txo, thiab qhov sib xws yuav tsis zoo. Tshwj xeeb dot matrix thiab lub vijtsam loj qhov kub nce siab muaj qhov cuam tshuam zoo rau kev ntseeg tau thiab ruaj khov ntawm LED. Yog li kev tsim hluav taws kub dissipation yog qhov tseem ceeb. Sib sib zog nqus ultraviolet LED teeb hlaws lub neej: Kev ua haujlwm ntev ntev ntawm kev sib sib zog nqus ultraviolet LED teeb hlaws yuav ua rau lub teeb laus, tshwj xeeb tshaj yog muaj zog sib sib zog nqus ultraviolet LED teeb hlaws. Thaum ntsuas lub neej ntawm qhov sib sib zog nqus ultraviolet LED teeb hlaws, nws tsis txaus siv qhov kev puas tsuaj ntawm lub teeb raws li qhov poob ntawm lub neej ntawm cov hlaws tob ultraviolet LED hlaws. Piv txwv li, 35%, qhov no yog qhov tsim nyog. Lub zog siab tob UV lub teeb emitting diode ntim: Ua ntej ntawm tag nrho cov, xav txog thaum tshav kub kub dissipation thiab tawm ntawm lub teeb. Nyob rau hauv cov nqe lus ntawm tshav kub dissipation, lub tooj liab-raws li radiator hauv ob sab phlu yog siv, thiab ces txuas nrog txhuas radiator. Cov nplej thiab cov cua sov hauv ob sab phlu yog welded. Txoj kev tshav kub dissipation zoo dua. Nyob rau hauv cov nqe lus ntawm lub teeb, xaiv lub nti inverted kev txawj ntse, thiab ntxiv qhov reflex nto kom muaj kev cuam tshuam lub teeb kom lwj lub teeb los ntawm lub hauv qab thiab sab, kom koj thiaj li tau txais ntau dua ntawm lub teeb.
