Qhov Zoo Ntawm Qhov Zoo Ntawm Qhov Ntawm Ntawm Ntawm LED Zaub

1, loj

Qhov loj ntawm LED cuam tshuam lub pixel deb ntawm LED zaub, piv txwv li kev daws teeb meem. Lub 5 hli elliptical LED yog tsuas yog siv rau sab nraum zoov cov zaub ntawm P16 thiab siab dua, thiab 3528 SMD LED yog siv rau cov khoom siv sab hauv cov zaub ntawm P6 thiab P8. Hauv qab qhov pom ntawm tas mus li cov suab nrov, qhov loj me ntawm LED nce, uas tuaj yeem ua rau thaj chaw muaj teeb meem loj dua thiab txo cov khoom noj. Txawm li cas los xij, vim tias txo qis ntawm thaj chaw dub, cov khoom zoo yog raug txo kom tsawg. Ntawm qhov tsis sib thooj, qhov loj me ntawm LED raug txo tsawg, cov zaub hauv thaj chaw raug txo kom tsawg, thiab cov nplej siab tau tsawg dua. Ua nce, thaj tsam ntawm thaj chaw dub ntxiv, nce qhov sib thooj.

2, ci ci

LED qaim yog qhov tseem ceeb ntawm kev txiav txim siab ntawm LED teeb ci. Qhov siab dua qhov ci ntawm LED, qhov ntau dua cov npoo ntawm qhov siv tam sim no, uas tau txais 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, lub ci ci dua ntawm LED, tab sis qhov tsawg dua lub kaum sab xis ntawm qhov pom ntawm cov LED teeb. Feem ntau, 100-degree LED yuav tsum raug xaiv los xyuas kom meej txaus saib lub kaum sab xis ntawm cov LED teeb. 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, xwm yeem

Cov puv LED zaub yog suav nrog suav tsis paub xim liab, ntsuab thiab xiav LED. Lub ci ci thiab lub teeb ntom ntom ntom ntom ntom ntom ntom nti ntawm txhua xim LED txiav txim siab lub teeb ci ci thiab dawb sib xws li qub tag nrho cov zaub. Chromatic sib xws. Feem ntau, LED cov chaw tsim khoom siv khoom siv yuav tsum tau muab cov khoom siv hluav taws xob tso nrog lub teeb hluav taws xob muaj qhov ntev 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.

4, tus nqi poob haujlwm

Txij li cov puv xim LED tso saib muaj li 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 pom ntawm cov LED zaub. Feem ntau, raws li kev paub dhau los ntawm kev lag luam, qhov tsis ua haujlwm ua ntej ua ntej cov zaub 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 nws tus kheej).

5, antistatic muaj peev xwm

Lub teeb hluav taws xob diodes yog cov khoom siv hluav taws xob semiconductor uas rhiab rau hluav taws xob zoo li qub thiab muaj kev cuam tshuam zoo rau cov hluav taws xob tsis ua haujlwm. Yog li no, antistatic muaj peev xwm tseem ceeb rau lub neej ntawm cov zaub. Feem ntau, tib neeg lub cev zoo li qub hom kev kuaj tsis ua hauj lwm voltage ntawm LED yuav tsum tsis qis dua 2000V.

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. Qhov xeeb ceem ntawm cov teeb ci ntsa iab ntawm LED yuav ua rau lub teeb pom kev zoo ntawm tag nrho cov zaub ntawm cov zaub kom tsawg. Qhov tsis sib xws ntawm lub teeb pom kev zoo ntawm liab, ntsuab thiab xiav LEDs tuaj yeem ua rau qhov tsis sib xws nyob rau hauv cov xim ntawm cov zaub LED, uas yog qhov peb nquag hais txog cov zaub. Highs LEDs muab kev tswj zoo ntawm lub teeb pom kev zoo. 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 LED teeb tsim, nyiam dua 70% Mus txog 80% ntawm cov sijhawm tam sim no. Ntxiv rau cov yam ntxwv ntawm liab liab, ntsuab thiab xiav LEDs, 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 LED.

7, 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. 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 siv hluav taws xob ci tshaj plaws, thiab sab hauv tsev coj los siv sab nraud uas siv kab rov tav lub teeb ci ntawm 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. 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 cov dawb tshuav ntawm cov ces kaum sib txawv, ncaj qha cuam tshuam rau lub fidelity ntawm cov zaub video xim. Txhawm rau kom ua tiav qhov sib xws ntawm qhov hloov pauv ntawm liab, ntsuab thiab xiav LEDs ntawm ntau lub kaum ntse ntse, nws yog qhov yuav tsum tau ua nruj me ntsis kev tsim qauv ntawm daim duab lub lens tsim thiab cov khoom siv raw xaiv, nyob ntawm seb theem kev ntawm pob khoom xa tuaj. 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 kev sib txawv ntawm cov LED tuaj yeem ntsuas los ntawm LED lub kaum ntse ntse sib tw tester, uas yog tshwj xeeb tshaj yog tseem ceeb rau kev qhia nruab nrab thiab qib siab.

8, lub neej tos

Lub theoretical lub neej ntawm LED yog 100,000 teev, uas yog ntau dua li lub neej ua haujlwm ntawm lwm cov khoom siv ntawm cov zaub LED. Yog li no, ntev npaum li qhov zoo ntawm LED yog qhov lav, qhov kev ua haujlwm tam sim no tsim nyog, qhov tsim ntawm PCB cua sov tsis sib haum yog qhov tsim nyog, thiab cov txheej txheem ntau lawm ntawm cov zaub yog cov khoom nruj, LED yuav yog tag nrho cov zaub. Ib qho ntawm feem ntau ruaj khov hauv tshuab. Cov teeb hluav taws xob tso tawm kom pom 70% ntawm tus nqi ntawm cov zaub, yog li LEDs tuaj yeem txiav txim siab txog cov khoom zoo. Tuam Tshoj yog lub teb chaws loj hauv kev tsim hluav taws xob teeb ci, thiab nws tseem yog qhov chaw sib sau ua ke rau LED pom. 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 LED coj los tshawb xyuas, txhawb Tuam Tshoj txoj kev hloov pauv los ntawm qhov loj loj LED cov khoom tsim tawm los ntawm lub teb chaws mus rau ib qho kev lag luam LED zaub.
