Koj tau pom zoo daim ntawv spec, lees paub tus nqi, thiab lub Hoobkas hais tias koj cov zaub LED tau npaj txhij rau nkoj. Tsis tas li ntawd nyob rau hauv peb lub hlis ntawm kev teeb tsa, ib qho puv tes ntawm cov modules dim, ob peb lub pixels tuag tshwm, thiab lub hwj chim ntawm lub txee rau rau pib coj tus cwj pwm tsis zoo. Feem ntau, cov teeb meem no tsis yog tsim teeb meem - lawv yog ntxov - lub neej ua tsis tiav uas qhov kev ntsuam xyuas kev laus yuav raug ntes ua ntej cov vaj huam sib luag puas tau tawm hauv lub hoobkas. Cov ntaub ntawv kev lag luam qhia tau hais tias cov khoom siv hluav taws xob ua tsis tiav ntawm lawv qhov siab tshaj plaws nyob rau thawj hnub ntawm kev ua haujlwm, tus qauv kev ntseeg siab engineers hu rau lub sijhawm "me nyuam mos tuag". Tsab ntawv xov xwm no piav qhia txog qhov kev ntsuam xyuas kev laus ntawm LED muaj qhov twg, nws yuav tsum tau ua haujlwm ntev npaum li cas, qhov tsis xws li nws nthuav tawm, thiab yuav ua li cas cov neeg yuav khoom tuaj yeem txheeb xyuas seb tus neeg muag khoom siv cov kauj ruam no tiag tiag - ua ntej xaj xaj.
Dab tsi yog qhov LED Zaub Aging Test?
Kev kuaj kev laus - qee zaum hu ua kev kub hnyiab- hauv kev sim - txhais tau tias khiav txhua qhov ua tiav LED zaub tsis tu ncua rau lub sijhawm ntev ua ntej ntim. Hloov chaw xa khoom ncaj qha tawm ntawm cov kab ntau lawm, cov chaw tsim khoom siv lub zog rau tag nrho cov tshuaj ntsuam, feem ntau ntawm tag nrho cov dawb los yog sib xyaw ntawm cov qauv ntsuas, thiab cia nws khiav mus rau 24 mus rau 72 teev lossis ntev dua.
Thaum lub qhov rais no, lub vijtsam ua haujlwm raws li hluav taws xob thiab thermal load:
Txhua LEDs tau txais kev tsav tam sim no txuas ntxiv, nthuav tawm cov chips tsis muaj zog
Cov khoom siv hluav taws xob khiav ntawm kev thauj mus los, qhia cov chav tsis ruaj khov
Tau txais daim npav thiab tswj cov txheej txheem txheej txheem teeb liab yam tsis muaj kev cuam tshuam
Thaum tshav kub kub accumulates nyob rau hauv lub txee, simulating ntsia tej yam kev mob
Nyob rau hauv luv luv, qhov kev ntsuam xyuas compresses thawj lub lis piam ntawm ib tug zaub ua hauj lwm lub neej nyob rau hauv ob peb hnub nyob rau hauv lub Hoobkas.
Dab tsi ua rau Kev Laus Catch?
Thaum ntxov-Lub neej tsis ua haujlwm feem ntau yog los ntawm cov khoom siv marginal - LEDs nrog cov pob qij txha tsis zoo, cov capacitors uas ntws hauv qab cua sov, lossis cov tsav tsheb ICs uas coj tsis zoo. Kev kub hnyiab tas mus li- ua rau cov tsis muaj zog no pom sai sai.
| Hom kev puas tsuaj | Cov tsos mob ntawm qhov chaw | Caught los ntawm Aging Test? |
|---|---|---|
| Tsis muaj zog lossis degraded LED nti | Dim module, brightness mismatch | Yog lawm |
| Cold solder sib koom / pluag weld | Flickering pixels, intermittent tuag kab | Yog lawm |
| Lub zog hloov pauv tsis ruaj khov | Random restarts, uneven brightness | Yog lawm |
| Faulty driver IC lossis txais daim npav | Scan kab, xim blocks | Yog lawm |
| Txee overheating tsis zoo tsim | Maj mam brightness poob thaum lub sij hawm | Ib nrab |
Tsis yog txhua qhov ntev - qhov teeb meem kev ntseeg siab tuaj yeem rov ua dua hauv 72 teev, tau kawg. Thermal tsim thiab waterproofing nyob ntawm qhov dav engineering, uas yog vim li cas kev laus xeem ua hauj lwm ib sab ntawm - tsis es tsis txhob ntawm - tsim kom muaj pov thawj thiab soj ntsuam.
Ntev npaum li cas?
Kev laus lub sijhawm sib txawv thoob plaws kev lag luam, thiab cov neeg yuav khoom tsim nyog paub qhov txawv:
8-12 hnub:Feem ntau ntawm cov nqi qis - cov khoom muag. Txaus kom ntes pom tseeb tuag pixels, me ntsis ntxiv.
24-48 hnub:Lub hauv paus tsim nyog. Feem ntau marginal Cheebtsam yuav ntog nyob rau hauv no ntau yam.
72h ib:Txaus siab rau cov haujlwm tseem ceeb - tshaj tawm cov studios, cov chaw hais kom ua, cov ntawv tshaj tawm loj - qhov twg ntawm - qhov chaw tsis ua haujlwm raug nqi ntau tshaj lub sijhawm ua haujlwm.
Yog li ntawd, thaum sib piv cov nqe lus, cov sij hawm laus yuav tsum yog ib feem ntawm kev sib tham, tsis yog tom qab. Ob lub vijtsam nrog cov qauv zoo ib yam tuaj yeem coj txawv txawv yog tias ib tus siv ob hnub nyob rau hauv lub Hoobkas thiab lwm qhov siv ob teev.
Lub Hoobkas Mature Ua li cas
Ntawm Litestar, 100% aging test ua ntej xa khoom yog txheej txheem txheej txheem es tsis yog kev xaiv xaiv. Txhua lub txee ua haujlwm ntawm peb cov kab tsim khoom hauv Shenzhen ua ntej ntim khoom, txhawb nqa los ntawm ISO9001-cov ntaub ntawv pov thawj zoo thiab CE / RoHS- cov khoom ua raws. Tib lub tswv yim txuas mus rau qhov seem ntawm cov txheej txheem tsim khoom: automated SMT qhov chaw tso cai txo cov teeb meem ntawm qhov chaw, thaum kev soj ntsuam nruj ua ntej qhov hlawv - ntawm nws tus kheej. Rau cov neeg yuav khoom, cov txiaj ntsig tau zoo yog qhov yooj yim - tsawg dua qhov ua tsis tiav, tsawg dua qhov hloov pauv hloov pauv hauv ib xyoos, thiab cov zaub uas ncav cuag nws qhov ntsuas lub neej.
5 Cov lus nug Cov neeg yuav khoom yuav tsum nug ua ntej xaj
Ua ntej koj paub meej txog kev yuav khoom LED, muab cov lus nug no rau koj tus neeg muag khoom:
- Muaj pes tsawg teev kuv cov ntxaij vab tshaus yuav muaj hnub nyoog ua ntej khoom xa tuaj- thiab puas yog sau rau hauv daim ntawv cog lus?
- Kev laus puas npog txhua lub txee, los yog tsuas yog ib qho piv txwv ntawm batch?
- Dab tsi kuaj cov qauv thiab qib brightnesssiv thaum hlawv -in?
- Kuv puas yuav tau txais daim ntawv qhia txog kev laus, nrog cov duab lossis video pov thawj?
- Yuav ua li cas yog hais tias ib tug module ua tsis tau tejyam thaum laus- puas yog qhov hloov pauv rov- sim, tsis yog hloov pauv?
Ib tus neeg muag khoom uas teb cov lus no kom ntseeg siab thiab sau ntawv feem ntau tau ua qauv txheej txheem. Ib tug uas dodges lawv, los yog cog lus "100% zoo" yam tsis tau piav qhia txog lub tshuab, tsim nyog saib thib ob.
Xaus
LED zaub yog lub sijhawm ntev - kev nqis peev hauv vaj tse, thiab lub vijtsam kim tshaj plaws yog qhov uas tsis ua haujlwm rau lub hlis tom qab kev teeb tsa. Kev ntsuam xyuas kev laus yog ib qho qis tshaj - tus nqi, siab tshaj - cov kauj ruam cuam tshuam hauv tag nrho cov saw hlau tsim khoom - tab sis nws feem ntau pom tsawg kawg rau cov neeg yuav khoom. Ua nws ib feem ntawm koj daim ntawv tshuaj ntsuam xyuas tus neeg muag khoom, nug rau daim ntawv tshaj tawm, thiab kho cov sijhawm laus raws li qhov tshwj xeeb, tsis yog kev saib xyuas.
