Dab tsi Ua rau Dawb LED nti tuag?

Ntau lub tuam txhab tsuas yog ntiav cov khoom pheej yig thiab cov khoom tsis zoo los txo tus nqi ntawm lub teeb kom ntxias cov neeg siv khoom. Tus nqi ntawm kev tsis txaus siab zoo txog WHITE LED vaj huam sib luag teeb tau nce hauv ob xyoos dhau los vim qhov no. Lub vaj huam sib luag teeb lub ntsej muag daj yog ib qho ntawm lawv, thiab nws yog qhov phem heev. Peb mam li tham txog cov laj thawj vim li cas Qwm dawb LED nti  ( 1 Khaulee 3: 1 - 5) Ua cas? Tsis muaj ntxiv ado, cia peb dhia txoj cai hauv.

Dab tsi yog dawb LED nti ?

Kev tsim lub teeb dawb nrog WHITE LEDs tuaj yeem ua tiav ob txoj kev sib txawv. Txoj hauv kev RGB yog thawj zaug, thiab txoj kev phosphor yog qhov thib ob. Txoj hauv kev phosphor yog ib qho uas nquag ua haujlwm hauv cov teeb pom kev zoo. Cov txheej txheem phosphor tsim ib pob WHITE LED uas tsim lub teeb dawb los ntawm txheej xiav dawb LED nti nrog daj phosphor.

Kev tsim lub teeb dawb nrog WHITE LEDs tuaj yeem ua tiav ob txoj kev sib txawv. Txoj hauv kev RGB yog thawj zaug, thiab txoj kev phosphor yog qhov thib ob. Txoj hauv kev phosphor yog ib qho uas nquag ua haujlwm hauv cov teeb pom kev zoo.

Los ntawm kev sib txuas cov xim liab, ntsuab, thiab xiav xim nyob rau hauv txoj cai proportions, lub teeb dawb yog tsim los ntawm cov txheej txheem RGB.

Cov txheej txheem phosphor tsim ib pob WHITE LED uas tsim lub teeb dawb los ntawm txheej xiav dawb LED nti  nrog daj phosphor. Cov txheej fluorescent daj tso cai rau lub teeb xiav tsim los ntawm cov dawb LED nti  kom dhau mus, tsim lub teeb dawb nrog kev sib xyaw ntawm blues thiab daj photons.

Nyob rau theem ntawm cov nti, lub teeb-emitting diode (LED) yog tsim los ntawm cov khoom siv semiconductor uas tau doped los ua p-n hlws ris. Los ntawm kev siv ib qho kev ncaj ncees tam sim no mus rau qhov sib txuas, ib tus tuaj yeem yuam cov electrons txav los ntawm n-type conduction band mus rau p-type conduction band. Qhov kev rov ua dua tshiab no yog cov txheej txheem hluav taws xob uas, feem ntau ntawm cov xwm txheej, ua rau tsim cov photon nrog lub wavelength uas txiav txim siab los ntawm bandgap ntawm cov khoom.

Tom qab tus qauv ntawm ib qho dawb LED  wafer, nws yog tom ntej hlais, thiab tus neeg tuag uas tsim cov wafer txuas thiab ntim. Nws yog ib qho tsim nyog los txuas rau WHITE LED  mus rau cov coj siv cov xov hlau zoo heev, uas feem ntau ua los ntawm kub, txhawm rau tsim kom muaj qhov tam sim no rau pem hauv ntej uas tsim nyog kom tau txais lub teeb tawm ntawm WHITE LED

Vim li cas dawb LED nti s Tuag?

WHITE LED feem ntau ntsib ib qho ntawm ob hom kev ua tsis tiav: kev loj hlob lossis kev puas tsuaj. Qhov tsis ua hauj lwm ntawm ib qho WHITE LED  yog feem ntau yuav tshwm sim los ntawm ib tug qeeb degeneration nyob rau hauv lub sij hawm raws li opposed mus rau ib tug tam sim ntawd transformation, nrog tsawg heev zam. Kev ua tsis tiav, nyob rau hauv lub qhov muag ntawm cov neeg muag khoom, tsis yog ob lub xeev tab sis yog ib qho kev sib cais ntawm qhov kev ua haujlwm txuas ntxiv. Raws li kev tshawb fawb, tib neeg lub qhov muag tsuas yog muaj peev xwm tshawb pom qhov kev hloov pauv mus txog 30 feem pua ​​​​ntawm cov luminous flux ua ntej cov zis ntawm lub teeb tau txo qis los ntawm qhov ntau. Raws li qhov tshwm sim ntawm qhov no, feem ntau ntawm cov neeg tsim khoom txhais lub neej voj voog ntawm ib lub cuab yeej raws li lub ntsiab lus ntawm nws cov zis luminous flux poob qis dua 70 feem pua ​​​​ntawm cov nqi nws tau pib.

Txawm li cas los xij, qhov no tsis tau txhais hais tias qhov kev puas tsuaj loj yuav tsis tshwm sim. Qhov tseeb, qhov yuav tshwm sim uas ib qho ntawm koj cov khoom siv yuav tsum tsis ua haujlwm zoo ntawm qee lub sijhawm nce ntxiv nrog rau qhov hnyav ntawm kev ua haujlwm. Txawm li cas los xij, muaj cov kev ntsuas uas koj tuaj yeem ua kom txo qis qhov cuam tshuam ntawm ntau yam ntawm cov xwm txheej no thiab ua rau muaj feem yuav tau txais koj daim ntawv thov.

Cov khoom ua tsis tiav

WHITE LED  kev ua tau zoo thiab kev ua neej nyob yog nyob ntawm cov khoom zoo. Electron-qhov recombination yuav ua rau nonradiative lwj yog hais tias cov khoom muaj ntau yam flaws. Feem ntau lub teeb dawb WHITE LEDs yog tsim los ntawm sapphire substrates them nrog GaN. Txoj hlua khi los ntawm lattice mismatch induces threading dislocations. Cov kab nrib pleb zoo propagated vertically los ntawm GaN zaj duab xis mus rau hauv cheeb tsam nquag, ua rau tsis muaj hluav taws xob lwj. Lub teeb tso zis txo qis thaum tsis muaj hluav taws xob tawg ntxiv. Thermocycling tuaj yeem nthuav tawm cov teeb meem no.

Cov dej xau tam sim no los ntawm cov qauv ua txhaum cai tso cai rov qab-bias tam sim no ntws. Kev txhaj tshuaj tiv thaiv kab mob los ntawm thaj chaw nquag tuaj yeem tsim lossis nthuav tawm qhov tsis xws luag. Kev tsis haum density txo qis kev tawg voltage, cuam tshuam kev ua haujlwm.

Cov tam sim no siab tuaj yeem ua rau muaj qhov tsis xws luag ntawm kev sib tshuam ntawm p-sab. Hluav taws xob kev nyuaj siab degraded ultraviolet WHITE LED s ntau tshaj thermal stress. Zhuhai Tianhui Electronic Co., Ltd.   txias-dawb LED yog zoo tagnrho rau ultra-ci daim ntaub ntawv. Qhov saum npoo - mounted ntaus ntawv tuaj yeem tuav 2.8 A rau pem hauv ntej rau 900 lm tso zis.

Overdriving ib tug dawb LED

Overdriving ib tug dawb LED  tuaj yeem ua rau cov zis thiab lub neej puas. Rau cov ntawv siv high-brightness, qhia ib lub cuab yeej zoo li no txias-dawb LED, uas tuaj yeem tso tawm 900 lm ntawm 2.8 A.

WHITE LED  kev txhaum tsis txwv rau cov xov xwm nquag. Epoxy encapsulate tiv thaiv qhov tuag, tab sis nws tuaj yeem ua teeb meem. Cov khoom nqus tau tuaj yeem hloov cov dej noo lossis cov tshuaj caustic mus rau qhov tuag nyob hauv qhov chaw ntub dej lossis corrosive ib puag ncig. Corroded hu tuaj yeem tsim luv luv lossis overvoltage. Passivation tuaj yeem txo cov nyhuv no, tab sis cov khoom siv yuav tsum tau tiv thaiv hauv qhov kub thiab txias.

Hluav taws xob ua txhaum

Electromigration, ib qho txheej txheem ntawm kev txhim kho los ntawm cov av noo lossis qhov xwm txheej ntub dej, tuaj yeem tsim cov filaments los ntawm cov hlau zoo li cov nyiaj hauv paste siv los ua raws li saum npoo-mount LEDs rau cov laug cam. Zam cov LEDs uas tsis yog-encapsulated.

WHITE LE D raug rau high-voltage electrostatic paug tej zaum yuav tsis muaj kev puas tsuaj loj. Ultra-high-voltage spikes yog muaj. Taug kev los ntawm chav tsev ntaub pua plag tuaj yeem them koj li 1.5 kV, nyob ntawm cov av noo thiab khau. Qhov kev poob siab tuaj yeem kov yeej cov khoom siv hluav taws xob semiconductor electrostatic thaum xa mus rau qhov tuag. Cov cua kub hauv cheeb tsam tsis zoo los ntawm qhov tso tawm tuaj yeem perforate cov xov xwm nquag, ua rau tsis ua haujlwm luv luv.

Yuav Qhov twg Dawb dawb LED nti  Qhov ntawd kav ntev dua

Zhuhai Tianhui Electronic Co., Ltd.  yog ib tug high-zoo UV LED manufacturers  tshwj xeeb hauv UV WHITE LED tsav huab cua sanitization, UV WHITE LED tsav dej ntxuav, UV WHITE LED tsav luam ntawv kho, uv Dawb LED diode , ua uv   coj Moda , thiab lwm yam. Nws muaj cov kws tshaj lij kev tshawb fawb thiab kev tsim kho thiab nthuav tawm cov neeg ua haujlwm los muab cov neeg siv khoom nrog UV WHITE LED tsav teeb tsa, thiab nws cov khoom kuj tau txais kev pom zoo thoob plaws cov neeg siv khoom.

Tianhui Hardware tau ua ib feem ntawm UV WHITE LED tsav pob nrog cov khoom tsim tag nrho, zoo ib yam thiab kav ntev, thiab tus nqi qis. Cov khoom muaj xws li UVA, UVB, thiab UVC los ntawm luv mus ntev zaus thiab cov ntaub ntawv qhia txog UV Radiation los ntawm qis mus rau siab zog.
