Cov neeg siv kev paub dhau los thiab kev ua haujlwm tau zoo yog cuam tshuam ncaj qha los ntawm kev ua haujlwm ruaj khov ntawm LED vaj huam sib luag, uas tau siv dav hauv kev tshaj tawm xov xwm, kev sib tham cov lus qhia, kev thauj mus los, thiab teeb pom kev sab nraum zoov.LED vaj huam sib luagunavoidably ntsib ntau yam teeb meem tom qab siv ntev lossis ua haujlwm tsis raug, uas tuaj yeem txo qis cov duab zoo thiab nce nqi kho. Nplooj ntawv no piav qhia txog ntau yam teeb meem ntawm LED vaj huam sib luag, nrog rau lawv cov tsos mob thiab cov hauv paus ntsiab lus, raws li kev paub hauv kev lag luam. Ntxiv nrog rau kev muab cov lus qhia kws tshaj lij rau cov neeg siv khoom uas muaj cov kev xav tau zoo sib xws, qhov no ua haujlwm rau cov kws tshaj lij tshwj xeeb hauv kev daws teeb meem thiab kev saib xyuas niaj hnub.
IUnusual Power Supply
Qhov tseem ceeb tshaj plaws thiab qhov teeb meem tshwm sim nrog LED panels yog cov khoom siv hluav taws xob tsis tu ncua, uas ncaj qha ua rau kev ua haujlwm tsis zoo lossis tsis ruaj khov. Hauv kev lag luam, nws kuj yog ib qho ntawm cov lus nug uas nquag nug thaum tshaj tawm - kev sib tham txog kev yuav khoom.
Cov tsos mob tseem ceeb: Lub vaj huam sib luag flickers ntau, sai sai tig dub, thiab tom qab ntawd rov pib nws tus kheej; tag nrho lub vijtsam tsis teeb; lossis ib feem ntawm qhov screen tsis teeb. Tsis sib xws module brightness kuj tuaj yeem tshwm sim hauv qee qhov xwm txheej.
Cov laj thawj tseem ceeb muaj xws li: Circuit Court overload lossis luv Circuit Court uas ua rau Circuit Court breaker tripping; fais fab mov voltage fluctuations tshaj lub vaj huam sib luag cov kev khiav hauj lwm ntau yam; teeb meem thaiv, xws li xoob, hnav, lossis tawg lub zog cables lossis oxidised terminals; thiab fais fab mov chav tsev (PSU) tsis ua hauj lwm, xws li tshuab fuse, puas transformer, los yog bulging capacitors.
Kev daws teeb meem yooj yim: Ua ntej, xyuas kom tseeb tias lub hwj huam sib txuas txuas txuas ruaj ntseg, nrhiav qhov kub hnyiab lossis tsw ntxhiab tsw txawv ntawm lub zog hluav taws xob, sim cov zis hluav taws xob nrog lub ntsuas ntsuas kom paub tseeb tias nws nyob hauv lub vaj huam sib luag qhov kev xaiv, nrhiav pom kev puas tsuaj, thiab pom tias nquag mus txuas ntxiv tom qab rov pib lub Circuit Court breaker.
Cov tsos mob txawv txawv
Qhov txiaj ntsig tseem ceeb ntawm LED vaj huam sib luag yog nws cov txiaj ntsig pom. Cov teeb meem no, uas nquag pom nyob rau sab hauv tsev me me -pitch panels thiab sab nraum zoov cov ntxaij vab tshaus, muaj kev cuam tshuam ncaj qha rau kev pom kev pom thiab yog qhov tseem ceeb ntawm cov neeg siv khoom tsis txaus siab.
Cov LED tuag (ib lossis ntau lub LEDs tsis teeb), cov kab ci / tsaus nti, lub vijtsam flickering, mosaic-zoo li cov tsos, xim tsis sib xws, xim sib txawv, qhov txawv txav ceev nrawm ntawm lub vijtsam, lossis cov duab tsis meej hauv qab lub teeb hnyav yog qhov tshwm sim tseem ceeb.
Cov laj thawj tseem ceeb muaj xws li: tsis zoo soldering, kev laus thiab kev puas tsuaj los ntawm kev siv ntev, lossis tsis zoo LED nti; calibration vaj huam sib luag tsis raug, uas ua rau tsis muaj qhov sib npaug RGB; inconsistent module batches, uas ua rau cov xim txawv txawv hauv LED chips; tsis txaus cua sov dissipation, nrog kub kub cuam tshuam rau LED nti luminous efficiency; thiab kev puas tsuaj rau LED chips thiab modules los ntawm kev cuam tshuam sab nraud.
Kev daws teeb meem yooj yim: Tshawb xyuas cov kiv cua txias thiab qhov cua qhov cua kom muaj kev cuam tshuam thiab cov plua plav; kho cov xim thiab ci ntsa iab siv cov software tswj los txiav txim qhov teeb meem teeb meem parameter; siv cov qauv ntsuas los nrhiav qhov chaw teeb meem thiab nrhiav kev puas tsuaj rau lub cev ntawm lub vaj huam sib luag.
Teeb meem nrog teeb liab kis tsis tau
Rau daim duab projection, LED panels cia siab rau cov teeb liab kis tau tus mob. Cov teeb liab tsis ua haujlwm, uas yog tshwj xeeb tshaj yog nyob rau hauv multi-module splicing cov ntxaij vab tshaus, feem ntau txuas rau kev tswj cov cuab yeej thiab cov kab sib txuas thiab yooj yim yuam kev rau vaj huam sib luag puas.
Duab tearing, misalignment, teeb liab poob uas ua rau tag nrho los yog ib feem ntawm cov zaub poob, duab stuttering, ghosting, los yog jumbled ntawv / rov qab dluab yog cov tsos mob tseem ceeb.
Cov hauv qab no yog cov laj thawj tseem ceeb: kev tswj tsis raug software tsis raug teeb tsa, xws li kev daws teeb meem lossis scanning txoj kev tsis sib haum nrog lub vaj huam sib luag; faulty kis los yog tau txais phaib los yog incompatible firmware versions; kev sib cuag tsis zoo los yog kev tawg ntawm cov kab sib txuas (network cable, ribbon cable), los yog electromagnetic cuam tshuam vim tsis muaj kev tiv thaiv cables; ntau dhau lub teeb liab kis tau tus mob, los yog tsis muaj lub teeb liab amplifier.
Kev daws teeb meem yooj yim suav nrog kev kuaj xyuas seb qhov xa tawm thiab txais daim npav qhov taw qhia teeb pom kev zoo li cas, rov pib dua cov cuab yeej tswj hwm, tshem tawm thiab rov txuas cov kab sib txuas, ntxuav cov kev sib tshuam, thiab hloov cov kab puas; kom paub tseeb tias cov tswj software tsis sib xws nrog cov vaj huam sib luag specifications; thiab txhim kho lub teeb liab amplifier rau kev sim yog tias qhov sib kis tau ntev dhau lawm.
Hardware Wear Issues thiab Environmental Adaptability
Kev siv ib puag ncig thiab kev saib xyuas niaj hnub yog qhov laj thawj tseem ceeb ntawm cov teeb meem no. Lub neej ntev ntawm lub vaj huam sib luag LED tuaj yeem ua rau luv luv los ntawm kev tsis saib xyuas ntev, tshwj xeeb tshaj yog rau sab nraum zoov LED vaj huam sib luag uas muaj kev cuam tshuam rau ib puag ncig. Hauv kev lag luam, qhov no yog lwm qhov teeb meem txij nkawm uas feem ntau tsis quav ntsej.
Dej nkag mus rau hauv cov vaj huam sib luag sab nraum zoov, foob tsis ua haujlwm, module deformation thiab cracking, xoob los yog detached interfaces, kev puas tsuaj rau LED hlaws los ntawm electrostatic paug, los yog yellowing thiab tseem ceeb plua plav buildup ntawm lub vaj huam sib luag nto tom qab siv txuas ntxiv yog lub ntsiab manifestations.
Cov hauv qab no yog cov laj thawj tseem ceeb: Tsis txaus los tiv thaiv- ntsuas zoo li qub nyob rau hauv ib puag ncig qhuav tso cai rau cov neeg ua haujlwm ncaj qha kov cov hlaws LED; Qhov kub sib txawv ntau dhau ua rau thermal expansion thiab contraction puas rau PCB substrate; aging sab nraum zoov vaj huam sib luag sealant thiab qhov khoob hauv cov qauv tso cai rau cov dej nag nkag rau hauv; Kev sib tsoo thiab kev sib tsoo thaum lub sij hawm thauj mus los thiab kev teeb tsa ua rau module deformation thiab loosening ntawm interfaces; thiab kub sib txawv ntau dhau ua rau thermal expansion
Kev daws teeb meem yooj yim: Tshawb xyuas lub sealing ntawm sab nraum zoov ua ntu zus thiab hloov cov sealant qub kom sai li sai tau; ntxuav lub vaj huam sib luag ntawm cov plua plav tsis siv cov tshuaj ntxuav corrosive; hnav tiv thaiv - lub dab teg zoo li qub thaum ua haujlwm thiab xyuas kom cov khoom siv hauv av zoo; txheeb xyuas qhov kho ntawm lub module thiab nruj ib qho xoob interfaces thiab screws kom sai li sai tau.
Thov tsis txhob yig tiv tauj nrog peb yog tias koj khiav mus rau ib qho teeb meem tshwj xeeb thiab xav tau cov kws tshaj lij kev daws teeb meem, cov lus pom zoo hloov ib feem, lossis cov kev xav tau cuam tshuam xws li kev yuav khoom, kho, lossis tswj cov vaj huam sib luag LED.
