Master zog xam rau LED zaub teeb pom kev zoo. Tshawb nrhiav qhov siab tshaj plaws piv rau qhov nruab nrab ntawm kev siv hluav taws xob, cov qauv tsim qauv ntsuab, thiab lub zog- txuag cov lus qhia.
Taw qhia
Kev khiav lag luam loj - teev cov duab digital suav nrog cov nqi hluav taws xob txuas ntxiv uas tuaj yeem ntxiv tau sai yog tias kev tswj hwm hluav taws xob tsis saib xyuas thaum lub sijhawm tsim. Ib qho kev txhawj xeeb tshaj plaws rau cov thawj tswj hwm qhov chaw yog ntsuas qhov kaj, siab - cuam tshuam kev pom nrog kev siv hluav taws xob ruaj khov. Los ntawm kev nkag siab li casLED zaub teeb pom kev zootuav cov khoom siv hluav taws xob thiab siv lub zog niaj hnub-txuag thev naus laus zis, koj tuaj yeem txo qis kev ua haujlwm ntawm lub taub hau thaum tswj hwm qhov ua tau zoo tshaj -tier.
Nkag siab txog kev siv hluav taws xob hauv cov ntxaij vab tshaus digital
Txhawm rau kom tau txais nyiaj txiag kom raug rau cov khoom siv hluav taws xob, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm qhov screen rub lub zog theoretically piv li cas nws ua haujlwm hauv txhua hnub. Acoj teeb pom kev zoo screentsis siv hluav taws xob zoo li qub; Hloov chaw, nws lub zog kos hloov pauv tas li raws li qhov kev xav tau pom.
Thaum xam cov kev xav tau fais fab rau azaub coj teeb pom kev zooinstallation, engineers saib ob lub ntsiab metrics: siab tshaj plaws hwj chim noj thiab nruab nrab hwj chim noj. Lub zog siab tshaj plaws tshwm sim tsuas yog thaum lub vijtsam tso tawm cov khoom, 100% cov duab dawb ntawm nws qhov chaw siab tshaj plaws. Hauv qhov sib piv, qhov nruab nrab siv hluav taws xob sawv cev rau kev siv niaj hnub niaj hnub- khiav cov ntsiab lus video txheem nrog cov xim sib xyaw thiab qhov chaw tsaus- uas feem ntau qis dua qhov siab tshaj qhov load.
Hom Fais Fab Kev suav thiab Infrastructure Scenarios
Kev npaj hluav taws xob tsim nyog ua kom ntseeg tau tias koj lub tsev daim phiaj hluav taws xob tuaj yeem txhawb nqa cov kev teeb tsa digital yam tsis muaj kev cuam tshuam.
Xam qhov Peak Hluav Taws Xob Load
Ua ntej txhim kho cov khoom siv kho vajtse, cov neeg cog lus hluav taws xob suav qhov siab tshaj plaws tag nrho cov amperage xav tau los ntawm kev ntxiv cov wattage ntawm tag nrho cov khoom ua ke. Piv txwv li, yog ib qho chaw sab hauvcoj teeb pom kev zoo rau kev nthuav qhiaarray muaj qhov ntsuas siab tshaj plaws ntawm 600 Watts ib square meter, lub thawv xa khoom tseem ceeb yuav tsum tau muab los tswj cov khoom siab tshaj plaws kom nyab xeeb, tiv thaiv hluav taws xob txaus ntshai thaum pib lub cev pib-ups.
Ntsuas Cov Nqi Ua Haujlwm Nruab Nrab
Thaum lub sijhawm ua haujlwm txheem, kev nthuav tawm cov qauv tshaj tawm lossis cov yeeb yaj kiab koom nrog yuav tsum muaj zog tsawg dua. Qhov nruab nrab lub zog kos feem ntau yog kwv yees kwv yees li ntawm ib qho -peb mus rau plaub caug feem pua ntawm qhov ntsuas hluav taws xob siab tshaj plaws, txhais tau tias koj daim nqi hluav taws xob ib hlis twg yuav qis dua qhov siab tshaj plaws kho vajtse specification qhia.
Siv zog-Txuag Drive Architectures
Ntau lub niaj hnub hwm cov ntxaij vab tshaus siv Common Cathode thev naus laus zis (ib qho kev faib hluav taws xob siab tshaj plaws uas muab cov khoom siv hluav taws xob uas xav tau los ntawm cov xim liab, ntsuab, thiab xiav diodes ib tus zuj zus, tsis yog xa cov hluav taws xob tsis zoo rau tag nrho peb). Vim tias cov LEDs liab yuav tsum muaj qhov tsawg dua li cov xiav thiab ntsuab, txoj kev no tshem tawm cov hluav taws xob ntau dhau uas yuav ua rau tsis muaj cua sov.
| Hom ntsuas | Lus Txhais / Cov Cai | Qhov tseem ceeb rau Kev Npaj Ua Haujlwm |
| Lub zog siab tshaj plaws | Khoom dawb screen ntawm 100% brightness | Dictates qhov yuav tsum tau loj ntawm breaker keyboards thiab lub ntsiab cables |
| Lub zog nruab nrab | Standard video playback nrog cov xim sib xyaw | Siv los xam cov nqi hluav taws xob txhua hli thiab ntev -ROI |
| Standby Fais Fab | Lub vijtsam yog xim dub tab sis tau txais cov cim tswj | Reflects thaum hmo ntuj lub zog kos thaum cov zaub tsis ua haujlwm |
Cov qauv tseem ceeb rau kev ua haujlwm ruaj khov
Thaum yuav khoom kho vajtse rau cov tuam txhab lossis cov phiaj xwm pej xeem, kev tshuaj xyuas kom ua raws li kev lees paub hluav taws xob thiab ib puag ncig cov qauv yog qhov tseem ceeb.
Power Factor Correction (PFC):Cov khoom siv hluav taws xob zoo muaj qhov sib xyaw ua ke PFC (ib lub tswv yim uas ua kom zoo dua qhov ua tau zoo ntawm kev xa hluav taws xob), kom ntseeg tau tias cov cuab yeej rub tawm tam sim no hauv cov nthwv dej du kom txo qis ntawm lub tsev hluav taws xob daim phiaj.
Thermal Dissipation Design:Xaiv cov khoom siv aluminium alloy ntau dua cov khoom siv yas uas pheej yig dua tuaj yeem txhim kho cov cua sov dissipation, txo qhov xav tau kom nrov, lub zog- siv cov kiv cua txias sab nraud.
Smart Brightness Teem caij:Siv lub teeb tsis siv neeg lub teeb sensors kom paub meej qhovcoj teeb pom kev zootso zis dims thaum lub sij hawm overcast hnub los yog hmo ntuj teev, tiv thaiv ib puag ncig ib puag ncig los ntawm lub teeb muaj kuab paug thaum txuag lub zog.
RoHS Ua raws:Ua kom covcoj teeb pom kev hauv qhov screenCheebtsam ua raws li RoHS (Txheej Txheem Kev Tiv Thaiv Cov Tshuaj Tiv Thaiv Kab Mob, uas txwv tsis pub siv cov khoom siv phom sij tshwj xeeb hauv cov khoom siv hluav taws xob) lav kev nyab xeeb dua qub thaum kawg ntawm cov khoom siv lub neej.
Summary and Infrastructure Recommendations
Optimizing lub zog profile ntawm koj cov duab digital yuav tsum xaiv cov khoom siv kho vajtse zoo thiab teeb tsa cov software ntse. Kev nqis peev hauv kev siv tshuab cathode feem ntau txo cov sijhawm ntev - cov nqi ua haujlwm thiab kev tsim hluav taws xob, uas ua rau ncua tag nrho lub neej ntawm cov diodes. Nws raug nquahu kom suav nrog lub zog theem- nyob rau hauv ib ntu hauv koj qhov kev tswj hwm kev tswj hwm, uas ua rau lub zog ntawm lub vijtsam sib txuas ntau dua li txhua lub sijhawm, tsis txhob muaj kev phom sij txaus ntshai.
Cov lus nug nquag nug (FAQs)
Kuv yuav suav li cas lub zog siab tshaj plaws uas xav tau rau kuv lub teeb pom kev LED?
Txhawm rau nrhiav qhov xav tau lub zog siab tshaj plaws, saib ntawm cov chaw tsim khoom cov ntawv qhia tshwj xeeb rau qhov "Maximum Power per Square Meter" kev ntsuam xyuas, thiab muab tus lej ntawd los ntawm tag nrho thaj chaw ntawm koj lub vijtsam. Qhov tag nrho tus nqi wattage no qhia rau koj tus kws kho hluav taws xob raws nraim li cas lub zog tseem ceeb yuav tsum tau muab.
Vim li cas cov ntsiab lus video cuam tshuam rau kev siv lub zog ntawm lub vijtsam coj teeb pom kev zoo?
LEDs yog emissive qhia, txhais tau tias txhua pixel tsim nws tus kheej lub teeb. Lub pixel dub emits tsis muaj lub teeb thiab siv yuav luag tsis muaj hwj chim, qhov kaj dawb pixel xav tau lub zog siab tshaj plaws, lub ntsiab lus tsaus nti video cov ntsiab lus ib txwm siv hluav taws xob tsawg dua li qhov ci, lub teeb - cov ntsiab lus xim.
Puas yog cov cathode zaub coj teeb pom kev zoo tsim nyog tus nqi pib?
Hauv cov ntawv thov kev lag luam feem ntau nrog cov sijhawm ua haujlwm ntev txhua hnub, yog. Vim tias nws txo qis kev tsim hluav taws xob thiab txiav hluav taws xob pov tseg, kev txuag hluav taws xob ntau dhau lub sijhawm feem ntau offset tus nqi pib dua me ntsis thaum txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv tshuaj ntsuam.
Dab tsi yog inrush tam sim no nyob rau hauv coj teeb pom kev zoo rau cov lus, thiab nws puas txaus ntshai?
Inrush tam sim no yog qhov hluav taws xob tam sim ntawd uas tshwm sim thaum lub sijhawm ua haujlwm loj loj tau qhib los ntawm lub zog tag nrho -down state. Yog tias tag nrho cov txee tig rau ntawm tib lub millisecond, qhov kev nce siab no tuaj yeem ua rau koj lub ntsiab hluav taws xob tawg; siv lub thawv fais fab sib txuas tiv thaiv qhov teeb meem no tag nrho.
Puas tuaj yeem tso cov teeb pom kev zoo coj mus ua haujlwm ntawm kev teeb tsa lub hnub ci?
Yog lawm, muab lub hnub ci array tau ua ke nrog cov khoom lag luam muaj roj teeb txaus txaus thiab lub zog hnyav - lub luag haujlwm inverter. Lub kaw lus yuav tsum tau tsim kho los tswj qhov siab tshaj plaws loads ntawm cov zaub kom ntseeg tau tias muaj hluav taws xob ruaj khov thaum lub sijhawm ua haujlwm.
