Advanced Facilities Efficient Production1, kev xav
Qhov pom lub kaum sab xis ntawm cov LED zaub yog txiav txim siab los ntawm saib lub kaum sab xis ntawm LED hlaws. Tam sim no, feem ntau ntawm cov ntxaij vab tshaus sab nraum zoov siv kab rov tav pom lub kaum sab xis ntawm 100 °; ib lub kaum ntse ntse ntsug ntawm 50 °; ib qho elliptical LED, thiab ib qho screen tso rau sab hauv tsev uas siv kab rov tav thiab ntsug 120 °; Cov zaub ntawm txoj kev loj yog feem ntau 30 ° vim nws qhov tshwj xeeb; lub voj voos LED nrog lub teeb pom kev pom yog txaus. Qee lub tsev siab siab xav tau txoj kev pom qhov siab dua. Lub kaum sab xis ntawm txoj kev pom thiab lub teeb ci yog qhov tsis sib xws, thiab lub kaum sab xis loj ntawm qhov pom tsim nyog yuav txo qhov kev ci ntsa iab. Qhov xaiv ntawm kev xav yuav tsum tau txiav txim siab raws li daim ntawv thov tshwj xeeb.
2, ci ci
LED qaim yog qhov tseem ceeb ntawm kev ua kom pom kev ci ntsa iab. Qhov siab dua qhov ci ntawm LED, qhov loj dua qhov npoo ntawm qhov siv tam sim no, uas muaj txiaj ntsig zoo rau kev txuag lub zog thiab ua kom cov LED nyob ruaj khov. LEDs muaj lub teeb sib txawv. Thaum lub teeb ci ntawm lub nti yog tsau, lub kaum sab xis me dua, ci dua rau LED, tab sis qhov pom me me ntawm lub kaum sab xis ntawm cov zaub. Feem ntau, 100 degree LED yuav tsum raug xaiv kom ntseeg tau pom lub kaum ntse ntse txaus ntawm cov zaub. Rau cov lus piav qhia nrog lub pob sib txawv thiab cov kab sib txawv ntawm qhov pom, qhov sib npaug yuav tsum pom muaj qhov pom kev, qhov pom thiab nqi.
3, tus nqi poob haujlwm
Txij li cov zaub puv xim suav ua li ntawm kaum tawm txhiab lossis ntau pua txhiab tus liab, ntsuab thiab xiav LEDs, qhov tsis ua tiav ntawm ib qho xim LED yuav cuam tshuam rau lub zuag qhia tag nrho cov nyhuv ntawm cov zaub. Feem ntau, raws li kev paub dhau los ntawm kev lag luam, qhov tsis ua haujlwm ua ntej qhov teeb meem LED pib sib sau ua ke rau kev laus 72 teev ua ntej kev thauj khoom yuav tsum tsis pub ntau tshaj peb txhiab txhiab (xa mus rau qhov tsis ua tiav los ntawm LED teeb nws tus kheej).
4, antistatic muaj peev xwm
LEDs yog cov khoom siv hluav taws xob semiconductor uas nkag siab rau hluav taws xob zoo li qub thiab tuaj yeem yooj yim ua rau electrostatic tsis ua haujlwm. Yog li no, antistatic muaj peev xwm tseem ceeb rau lub neej ntawm cov zaub. Feem ntau, LED tib neeg lub cev zoo li qub hom kuaj tsis ua hauj lwm voltage yuav tsum tsis txhob qis dua 2000V.
5, lub neej
Lub theoretical lub neej ntawm cov cuab yeej LED yog 100,000 teev, uas yog ntau dua li lub neej ua haujlwm ntawm lwm cov khoom siv ntawm cov coj teeb liab. Yog li no, ntev npaum li LED cov khoom lag luam zoo tau lees tias, kev ua haujlwm tam sim no haum, PCB txheej hluav taws xob tsim yog tsim nyog, thiab cov txheej txheem tsim cov khoom tso tawm kom nruj, cov khoom siv LED yuav yog cov vijtsam zaub. Ib qho ntawm feem ntau ruaj khov hauv tshuab.
Cov khoom siv LED tso tawm 70% ntawm tus nqi ntawm cov LED zaub, yog li cov khoom siv LED tuaj yeem txiav txim siab qhov zoo ntawm cov LED zaub. Tuam Tshoj yog lub teb chaws loj hauv kev ua cov cuab yeej hluav taws xob LED, thiab nws tseem yog qhov chaw sib sau ua ke rau cov tso saib LED. Cov cuab yeej tseem ceeb ntawm LED zaub yog lub neej tom ntej kev txhim kho. Cov khoom lag luam zoo ntawm cov LED zaub tsis yog tsuas yog cuam tshuam txog kev coj ntawm cov lag luam LED zaub, tab sis kuj tseem txhim kho cov LED zaub ntaus cov khoom lag luam. Los ntawm cov khoom siv LED tshawb xyuas, txhawb Tuam Tshoj txoj kev hloov pauv los ntawm qhov loj loj LED cov khoom tsim tawm ntawm lub teb chaws mus rau ib qho kev lag luam LED zaub.
6, attenuation yam ntxwv
Thaum LED coj los ua haujlwm ntev ntev, qhov ci ntsa iab yuav poob thiab xim xim rau cov zaub yuav tsis haum, feem ntau vim yog qhov ci ntsa iab ntawm cov khoom siv LED. Kev ua haujlwm ntawm lub teeb ci ntawm LED yuav ua rau lub teeb pom kev zoo ntawm tag nrho cov zaub ntawm cov zaub kom tsawg. Cov teeb ci tsis xwm yeem ntawm lub teeb liab, ntsuab thiab xiav xiav yuav ua rau tsis sib xws hauv cov xim ntawm cov zaub LED, uas yog qhov peb nquag hais txog cov zaub. Cov khoom siv hluav taws xob zoo hauv LED muab kev tswj zoo heev ntawm lub teeb pom kev zoo ci. Raws li 1000 teev ntawm kev kub lub teeb pom kev zoo 20mA tus qauv, liab attenuation yuav tsum tsawg dua 2%, xiav thiab ntsuab attenuation yuav tsum tsawg dua 10%, yog li xiav thiab ntsuab LED yuav tsum tsis txhob siv 20mA tam sim no hauv cov qauv tsim, dua li 70% rau 80%% ntsuas tam sim no.
Ntxiv rau cov yam ntxwv ntawm liab liab, ntsuab thiab xiav LED, cov yam ntxwv ntawm tus cwj pwm tau cuam tshuam los ntawm qhov tam sim no, cov qauv kub tawm ntawm PCB, thiab qhov kub thiab txias ntawm cov zaub.
7, loj
Qhov loj ntawm LED ntaus ntawv cuam tshuam lub pixel taw tes nrug ntawm LED zaub, piv txwv li kev daws teeb meem. Lub 5 hli elliptical teeb lub zog yog siv rau sab nraum zoov zaub saum P16, 3mm elliptical teeb yog tsuas yog siv rau sab nraum zoov cov zaub ntawm P12.5, P12 thiab P10, thiab 3528 hom thaj LED yog siv rau cov khoom siv sab hauv teeb ntawm P6 thiab P8. 2020 hom SMD LED yog siv rau cov khoom siv sab hauv xws li P2 thiab P3. Raws li qhov pom ntawm tas mus li cov suab nrov, LED qhov loj me ntawm cov khoom siv nce, uas tuaj yeem ua rau thaj chaw teeb tsa ntau dua thiab txo cov nplej siab. Txawm li cas los xij, vim tias txo qis ntawm thaj chaw dub, cov khoom zoo yuav raug txo kom tsawg. Ntawm qhov tsis sib thooj, LED loj dua yog txo, thaj chaw zaub tsawg dua, thiab qhov khoom noj tau nce ntxiv. Thaj tsam thaj tsam ntawm thaj tsam dub ntxiv thiab qhov sib piv yog nce.
8, xwm yeem
Cov zaub puv xim yog suav nrog suav tsis paub xim liab, ntsuab thiab xiav LED. Lub ci ci thiab lub teeb ntom ntom ntom ntom ntom ntom nti ntawm txhua xim LED txiav txim siab lub teeb ci ntsa iab, dawb tshuav xwm yeem thiab sib luag ntawm cov zaub txhua yam. Poj niam txiv neej. Feem ntau, cov tsim cov khoom lag luam xav tau cov cuab yeej muag khoom kom muaj LEDs nrog ib nthwv kab ntawm 5 nm thiab qhov ci ntau ntawm 1: 1.3. Cov kev qhia tshwj xeeb no tuaj yeem ua tiav los ntawm cov neeg xa khoom los ntawm lub tshuab hluav taws xob muaj xim zoo nkauj. Lub sib xws ntawm qhov hluav taws xob feem ntau tsis xav tau.
Txij li thaum cov LED taws teeb ntawm lub kaum, qhov puv xim LED zaub tseem muaj qhov sib tw ntawm lub kaum ntse ntse, uas yog, qhov ci ci tau nce lossis poob thaum pom ntawm ntau cov ces kaum. Ua li no, lub ntsej muag angular ntawm liab, ntsuab, thiab xiav LEDs yuav cuam tshuam loj heev kom sib xws ntawm dawb tshuav ntawm cov ces kaum sib txawv, ncaj qha cuam tshuam rau lub fidelity ntawm cov zaub video xim. Txhawm rau kom muaj qhov sib xws ntawm qhov hloov pauv ntawm lub teeb liab, ntsuab thiab xiav LED ntawm ntau lub kaum sab xis, nws yog ib qho tsim nyog yuav tsum ua kom ncaj qha rau kev tsim qauv ntawm kev teeb tsa ntawm lub ntim teeb tsim thiab cov khoom siv xaiv, nyob ntawm qib theem kev ntawm lub ntim khoom muag. Hauv kev coj ua qub, dawb paug yog zoo. Yog hais tias lub kaum sab xis ntawm LED tsis zoo ib yam, cov nyhuv dawb tshuav ntawm cov ces kaum sib txawv ntawm qhov screen tag nrho yuav tsis zoo. Lub kaum sab xis tsis sib luag ntawm LED teeb hlaws teeb tuaj yeem ntsuas los ntawm LED lub kaum ntse ntse ntsuas tester, uas yog qhov tshwj xeeb tshaj yog rau cov khoom nruab nrab thiab qib siab.
