1. Saib lub kaum sab xis
Lub kaum sab xis saib ntawm LED zaub nyob ntawm qhov pom lub kaum sab xis ntawm LED teeb. Tam sim no, feem ntausab nraum zoov LED zaubthiabsab hauv tsev LED zaub screen siv SMD LEDs nrog kab rov tav thiab ntsug saib lub kaum sab xis ntawm 140 °. Lub tsev siab LED cov lus qhia yuav tsum muaj ntau dua ntsug saib cov ces kaum. Lub kaum sab xis saib thiab ci ntsa iab yog qhov tsis sib xws, thiab lub kaum sab xis pom loj yuav ua rau txo qis qhov ci. Kev xaiv ntawm lub kaum sab xis yuav tsum tau txiav txim siab raws li kev siv tshwj xeeb.
2. Kev ci ntsa iab
Lub ci ci ntawm LED teeb hlaws yog qhov tseem ceeb ntawm kev txiav txim siab ntawm qhov ci ntawm LED zaub. Qhov siab dua qhov ci ntsa iab ntawm LED, qhov ntau dua cov npoo ntawm qhov siv tam sim no, uas yog qhov zoo rau kev txuag hluav taws xob thiab ua kom lub LED ruaj khov. LEDs muaj lub kaum sab xis sib txawv. Thaum lub ci ci ntawm lub nti yog tsau, lub kaum sab xis me dua, lub teeb ci dua LED, tab sis qhov pom lub kaum sab xis me dua. Feem ntau, 120-degree LED yuav tsum raug xaiv los ua kom pom lub kaum sab xis txaus ntawm cov zaub. Rau cov lus qhia nrog qhov sib txawv dot pitches thiab saib sib txawv, qhov sib npaug yuav tsum pom nyob rau hauv qhov ci, lub kaum ntse ntse thiab tus nqi.
3. Tus nqi ua tsis tiav
Txij li thaumpuv xim LED zaub yog tsim los ntawm kaum tawm txhiab lossis txawm ntau pua txhiab tus pixels uas muaj cov xim liab, ntsuab thiab xiav LEDs, qhov tsis ua haujlwm ntawm ib qho xim LED yuav cuam tshuam rau qhov pom ntawm tag nrho cov duab LED. Feem ntau hais lus, qhov tsis ua hauj lwm ntawm LED zaub yuav tsum tsis txhob siab tshaj 3/10,000 ua ntej LED zaub pib sib sau ua ke thiab hnub nyoog rau 72 teev ua ntej xa khoom.
4. Antistatic muaj peev xwm
LED yog cov khoom siv hluav taws xob semiconductor, uas nkag siab rau hluav taws xob zoo li qub thiab tuaj yeem ua rau hluav taws xob tsis zoo. Yog li ntawd, lub peev xwm los tiv thaiv zoo li qub tseem ceeb heev rau lub neej ntawm lub vijtsam zaub. Feem ntau hais lus, qhov tsis ua hauj lwm voltage ntawm LED tib neeg lub cev electrostatic hom kuaj yuav tsum tsis txhob qis dua 2000V.
5. Kev sib raug zoo
Tag nrho xim LED zaub screen yog tsim los ntawm pixels uas muaj ntau yam liab, ntsuab, thiab xiav LEDs. Qhov sib xws ntawm qhov ci ntsa iab thiab wavelength ntawm txhua xim LED txiav txim siab qhov ci ci sib xws, qhov sib npaug ntawm cov xim dawb, thiab chromaticity sib xws ntawm tag nrho cov zaub screen.
Tag nrho cov xim LED zaub muaj angular directionality, uas yog, nws brightness yuav nce los yog txo thaum saib los ntawm ntau lub ces kaum. Nyob rau hauv txoj kev no, qhov sib xws ntawm cov xim liab, ntsuab, thiab xiav LEDs yuav cuam tshuam rau qhov sib npaug ntawm qhov sib npaug ntawm cov ces kaum sib txawv, thiab cuam tshuam ncaj qha rau kev ncaj ncees ntawm cov xim video ntawm cov zaub. Txhawm rau kom ua tiav qhov sib xws ntawm qhov ci ci hloov pauv ntawm cov xim liab, ntsuab thiab xiav LEDs ntawm cov ces kaum sib txawv, nws yog ib qho tsim nyog yuav tsum nruj me ntsis ua raws li kev tsim qauv hauv kev tsim lub lens ntim thiab xaiv cov khoom siv raw, uas nyob ntawm qib kev txawj ntse. tus neeg muab khoom ntim. Txawm hais tias qhov kev coj ua zoo li qub yog qhov zoo li cas, yog tias LED lub kaum sab xis tsis zoo, qhov sib npaug dawb ntawm cov ces kaum sib txawv ntawm tag nrho cov vijtsam yuav tsis zoo.
6. Attenuation yam ntxwv
Tom qab LED zaub ua haujlwm ntev, qhov ci ntsa iab yuav poob thiab cov xim ntawm cov zaub yuav tsis sib haum, uas feem ntau tshwm sim los ntawm qhov ci ntsa iab ntawm cov khoom siv LED. Lub attenuation ntawm LED brightness yuav txo qhov ci ntawm tag nrho LED zaub screen. Qhov tsis sib xws ntawm qhov ci ntsa iab ntawm cov xim liab, ntsuab thiab xiav LEDs yuav ua rau qhov tsis sib xws ntawm cov xim ntawm LED zaub. High quality LED teeb yuav zoo tswj qhov loj ntawm brightness attenuation. Raws li tus qauv ntawm 20mA teeb pom kev zoo nyob rau hauv chav tsev kub rau 1000 teev, liab attenuation yuav tsum tsawg tshaj li 2%, thiab xiav thiab ntsuab attenuation yuav tsum tsawg tshaj li 10%. Yog li ntawd, sim tsis txhob siv 20mA tam sim no rau xiav thiab ntsuab LEDs hauv cov qauv tsim, thiab nws yog qhov zoo tshaj plaws los siv tsuas yog 70% mus rau 80% ntawm cov ntsuas tam sim no.
Ntxiv nrog rau cov yam ntxwv attenuation muaj feem xyuam rau cov yam ntxwv ntawm cov xim liab, ntsuab thiab xiav LEDs lawv tus kheej, tam sim no siv, lub tshav kub dissipation tsim ntawm PCB pawg thawj coj saib, thiab ambient kub ntawm cov zaub screen txhua yam cuam tshuam rau attenuation.
7. Loj
Qhov loj ntawm LED ntaus ntawv cuam tshuam rau pixel nrug ntawm LED zaub, uas yog, kev daws teeb meem. Hom SMD3535 LEDs feem ntau yog siv rauP6, P8, P10 sab nraum zoov LED zaub, SMD2121 LED yog tsuas yog siv rauP2.5,P2.6,p2.97 ua,p3.91 ua sab hauv tsev screen . Ntawm qhov chaw uas lub pixel pitch tseem tsis hloov pauv, qhov loj ntawm LED teeb nce, uas tuaj yeem ua rau thaj tsam tso saib thiab txo cov graininess. Txawm li cas los xij, vim qhov txo qis ntawm cheeb tsam dub, qhov sib piv yuav raug txo. Ntawm qhov tsis sib xws, qhov loj ntawm LED txo qis,uas txo qhov chaw tso saib thiab ua kom cov graininess, qhov chaw dub nce, nce qhov sib piv.
8. Kev ua neej nyob
Qhov theoretical lifespan ntawm LED teeb yog 100,000 teev, uas yog ntev npaum li cas ntawm lwm yam khoom ntawm LED zaub lifespan. Yog li ntawd, ntev npaum li qhov zoo ntawm cov teeb ci LED tau lees paub, kev ua haujlwm tam sim no tsim nyog, PCB tshav kub dissipation tsim tsim nyog, thiab cov txheej txheem tsim khoom yog nruj, LED teeb yuav yog qhov ruaj khov tshaj plaws rau LED video phab ntsa.
LED modules suav txog 70% ntawm tus nqi ntawm LED zaub, yog li LED modules tuaj yeem txiav txim siab qhov zoo ntawm LED zaub. Kev siv thev naus laus zis siab ntawm LED zaub screen yog qhov kev txhim kho yav tom ntej. Los ntawm kev tswj hwm ntawm LED modules, los txhawb Tuam Tshoj txoj kev hloov pauv los ntawm lub teb chaws loj LED zaub tsim rau lub teb chaws muaj zog LED zaub tsim.
