Koj puas tau ntsib ntau yam teeb meem uas tsis to taub, thiab cov teeb meem ntau dua yog dab tsi? Vim li cas lub teeb-emitting diode tsis tuaj yeem overvoltage lossis overcurrent siv lub teeb dawb LED? Cias muab, nws tau piav qhia los ntawm feem ntau siv 5 hli dawb lub teeb LED. Nws ib txwm ua hauj lwm voltage feem ntau yog nyob rau hauv 3.0-3.5V ntau yam, thiab ib txwm ua hauj lwm tam sim no yog 20mA 20mA. Txawm li cas los xij, ntau tus neeg yuam kev xav tias kev siv lub teeb dawb LED nrog dhau-voltage lossis overcurrent yuav ci dua, thiab qhov kev sim tiag tiag yog tias tom qab 15mA, qhov kho qhov muag flux nce sharply. Tom qab 20mA, yuav luag tsis pom-dhau. Tab sis muaj qhov pom tseeb ua npaws. Kuj tseem muaj qhov kev sim ntawm lub neej: 20mA tau ua haujlwm rau ib hlis, thiab qhov attenuation tsuas yog 5%. Tam sim no muaj 95% optical flux. Thaum 30mA ua haujlwm txog 19 hnub, qhov ntim ntawm lub teeb tsuas yog 50%. Nws tuaj yeem suav hais tias lub teeb dawb LED uas tuaj yeem ua haujlwm 100,000 teev nyob rau hauv ib txwm muaj kev siv hauv cov dej ntws loj, nrog lub neej ntev ntawm tsuas yog 600 teev! LEDs tuaj yeem siv tau ntau dua 50,000 teev hauv cov lus piav qhia dav dav, thiab qee cov tuam ntxhab hais tias Nws LED tuaj yeem ua haujlwm txog 100,000 teev, tab sis qhov no tsis tau lees tias cov khoom siv LED tuaj yeem siv tau ntev. Kev ua haujlwm tsis raug thiab txheej txheem tuaj yeem yooj yim
“Ua kom puas
”LEDs, LEDs yuav maj mam degenerate lub sij hawm. Qee qhov kev kwv yees qhia tau tias cov LEDs zoo tuaj yeem tswj tau ntau dua 60% ntawm qhov pib lub teeb ci tom qab 50,000 teev ua haujlwm tas li. Txhawm rau txuas ntxiv lub neej ntawm LED, nws yog ib qho tsim nyog los txo lossis tshem tawm tag nrho cov thermal zog tsim los ntawm LED nti. Lub zog hluav taws xob yog qhov laj thawj tseem ceeb vim li cas LED tsis ua haujlwm. Qhov no tau piav qhia rau kev siv lub teeb-emitting diodes. Yog xav paub ntxiv, thov hu rau kev sib tham txog kev pabcuam hauv online rau cov neeg siv khoom xav paub ntxiv.

Tau txais kev sib cuag nrog peb
UV LED diodes tau dhau los ua ntau yam kev siv, suav nrog tshuaj tua kab mob, kho kho, thiab lub teeb tshwj xeeb. Lawv tus nqi tshwm sim los ntawm lawv lub peev xwm los xa cov teeb pom kev zoo thiab ua haujlwm tau zoo raws li tus neeg yuav tsum tau ua. Classical mercury teeb, uas tau ua lub luag haujlwm sib piv, tau hloov pauv tsis tu ncua nrog UV LED diodes txij li lawv cov kev ua tau zoo dua thiab kev nyab xeeb. Kab lus no piav qhia vim li cas UV LED diodes yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov tam sim no.
Lub teeb UV ib leeg uas tuaj yeem pib txoj kev kho UV plaub caug xyoo dhau los yog mercury-based arc teeb. Txawm tias
Excimer teeb
thiab microwave qhov chaw tau tsim, thev naus laus zis tsis hloov. Zoo li lub diode, ib qho ultraviolet teeb-emitting diode (LED) tsim p-n hlws ris siv p- thiab n-hom impurities. Cov cab kuj raug thaiv los ntawm ib qho kev sib tshuam ciam teb depletion tsam.
