Yuav ua li cas tswj lub kaw lus ntawm LED zaub fais fab mov thiab nws cov teeb meem
Niaj hnub no, kev hloov pauv ntawm lub zog thev naus laus zis tau dhau los ua qhov tseem ceeb tshaj plaws rau kev tsim cov khoom siv LED, yog li peb yuav tsum nkag siab txog cov teeb meem tam sim no ntawm kev siv tshuab hluav taws xob ntau dua:
PCB Circuit Court layout tsim. Qhov hnyav ntawm LED zaub lub thawv cuam tshuam qhov loj ntawm cov khoom siv hluav taws xob, yog li PCB board tsim yuav tsum tau txo qis kom ntau li ntau tau, yog li tseem muaj ntau yam los xav txog. Tsis tsuas yog peb yuav tsum xyuam xim rau kev nyab xeeb nyob deb, tab sis peb kuj yuav tsum xav txog qhov drilling, waterproofing thiab plua plav tiv thaiv, thiab sealing rwb thaiv tsev kua nplaum. Cov ntxaij vab tshaus sab hauv tsev yuav tsum tau them nyiaj ntau dua rau cov cua kub dissipation, thiab kev xaiv thiab faib cov khoom cua sov yog qhov tseem ceeb tshwj xeeb kom tsis txhob muaj qhov kub thiab txias hauv zos. Cov khoom siv hluav taws xob yuav tsum tau khaws cia kom deb ntawm qhov chaw cua sov kom qeeb kev laus thiab ua kom lub neej ntev ntawm cov khoom siv hluav taws xob.
Cov khoom pov thawj. Tam sim no, tsis muaj daim ntawv pov thawj tus qauv rau LED cov ntxaij vab tshaus hauv Suav teb, thiab cov tuam haujlwm tseem ceeb hauv tebchaws tseem tab tom kawm thiab tsim nws. Cov ntxaij vab tshaus muag muag hauv tebchaws tseem nyob ntawm ntug kev tswj hwm, thaum cov khoom xa tawm tau lees paub nrog CE lossis UL. Hauv kev teb rau qhov xwm txheej tam sim no, nws yog qhov nyuaj heev rau kev tsim cov khoom siv fais fab kom tau raws li tag nrho cov ntawv pov thawj saum toj no ib txhij. Cov neeg tsim khoom yuav tsum siv sijhawm ntev los ua cov kev hloov kho tshiab los sim ua kom tau raws li cov ntawv pov thawj sib txawv thiab ua tau raws li cov neeg siv khoom xav tau.
Kev xaiv cov khoom siv. Thaum cov khoom lag luam kub ntawm LED teeb nyob ntawm 50 degrees, qhov kub ntawm cov khoom siv hluav taws xob yog nyob ib puag ncig 20 degrees, thaum qhov kub ntawm cov khoom yuav ncav cuag 70 degrees. Cov xwm txheej kub kub tuaj yeem ua rau tsis muaj kev cuam tshuam hauv qee yam khoom, uas tuaj yeem ua rau lawv lub neej ua haujlwm luv. Yog li ntawd, cov khoom siv yuav tsum raug xaiv uas tuaj yeem ua haujlwm ntev ntev ntawm qhov kub thiab txias, xws li electrolytic capacitors, xov hlau, thiab lwm yam.
Kev tsim hluav taws xob ua haujlwm. Lub hwj chim mov rau LED cov ntxaij vab tshaus yog tsim los rau qhov tsis tu ncua tam sim no. Qhov loj ntawm qhov tam sim no txiav txim siab qhov ci ntawm LED zaub screen. Yog hais tias qhov yuam kev tam sim no ntawm tib batch ntawm cov ntxaij vab tshaus loj, qhov ci ntawm lub vijtsam yuav tsis sib npaug. Thiab kev hloov pauv kub kuj tuaj yeem ua rau cov zis tam sim no ntawm cov khoom siv hluav taws xob hloov pauv, yog li nws yog qhov tsim nyog los tswj qhov kev ua yuam kev ntawm tib lub phiaj xwm zaub screen txhawm rau txhawm rau ua kom pom tseeb ntawm daim duab.
Tsim lub zog. Txawm hais tias LED teeb pom kev zoo muaj kev ua haujlwm siab, ze li ntawm 80% ntawm cov hluav taws xob hluav taws xob tseem poob, ua rau qhov kub thiab txias ntawm cov module thiab lub thawv nce. LED zaub cov ntxaij vab tshaus ntsia sab hauv tsev yuav ncav cuag 50 degrees hauv lub thawv ntawm chav tsev kub. Lub hwj chim mov yuav ua hauj lwm nyob rau hauv ib tug high-kub ib puag ncig rau ib tug ntev lub sij hawm, thiab kom ntseeg tau tias nws lifespan, nws yog tsim nyog los ua kom lub hwj chim margin.
Lub thawv kub dissipation. Lub vijtsam LED zaub yog lub teeb ci txias, thiab qhov chaw ua haujlwm kub tsis tuaj yeem tshaj qhov txwv. Kev tsim ntawm lub thawv ntim khoom yuav tsum xav txog cov teeb meem xws li kev zoo nkauj, kev teeb tsa yooj yim, cov duab zoo, thiab cov ntaub thaiv npog cov cua sov, txhawm rau tsim cov khoom lag luam kom tau raws li cov neeg siv khoom txaus siab. Lub sijhawm txhim kho ntawm LED cov ntxaij vab tshaus tsis ntev, thiab cov kev paub dhau los tseem tsis tau zoo tag nrho, yog li tsis muaj kev paub ntau yam uas tuaj yeem qiv. Ntau lub tuam txhab tsis xyuam xim rau cov cua kub dissipation thaum tsim cov ntxaij vab tshaus LED sab hauv tsev, feem ntau ua rau overheating ntawm lub thawv vim qhov chaw me me los yog tsis muaj qhov cua, uas cuam tshuam rau kev ua haujlwm ntawm lub vijtsam.
