Tshawb xyuas cov txheej txheem kev yuav khoom rau lub teeb pom kev dub los ntawm kev kawm yuav ua li cas ntsuas cov kev qhia tshwj xeeb, txheeb xyuas cov ntawv pov thawj, thiab sib piv cov neeg muag khoom quotes.
Kev txiav txim siab txog kev yuav khoom
Thaum koj tau xaiv qhov zoo meej pixel suab thiab qhov chaw rau koj qhov siab - qhov sib piv video phab ntsa, cov kauj ruam kawg yog taw qhia cov txheej txheem yuav khoom. Kev lag luam khoom lag luam suav nrog ntau yam ntawm cov neeg muag khoom uas muab cov kev qhia tshwj xeeb sib txawv thiab cov qauv nqi. Txhawm rau kom muaj kev ruaj ntseg siab -kev ua tau zoo uas muab sijhawm ntev- tus nqi, cov neeg yuav khoom yuav tsum paub yuav ua li cas thiaj li nyeem cov ntawv qhia tshwj xeeb thiab ntsuas cov lus pom zoo ntawm tus neeg muag khoom.
Zam kev pheej hmoo ntawm Cov Cheebtsam uas tsis tau lees paub
Thaum ntsuas qhov kev sib tw, nws tuaj yeem ntxias kom xaiv qhov qis tshaj qhov tsocai. Txawm li cas los xij, cov khoom siv pheej yig tsis zoo feem ntau txuag cov nqi los ntawm kev siv cov diodes generic LED, cov khoom siv hluav taws xob tsis muaj pov thawj, lossis qis dua - cov chips tsav tsheb zoo. Cov kev cuam tshuam no tuaj yeem ua rau cov xim tsis sib xws, flickering ntawm lub koob yees duab, thiab siab dua pixel tsis ua haujlwm nyob rau lub sijhawm, tshem tawm txhua qhov kev txuag nyiaj.
Tseem ceeb Technical Specifications los xyuas kom meej
Thaum tshuaj xyuas cov lus pom zoo los ntawm cov chaw tsim khoom lag luam, ua tib zoo mloog rau ntau lub hauv paus kev ntsuas kev ntsuas.
Txheeb xyuas Diode thiab Tsav Tsheb Chip Hom
Qhov kev ua tau zoo ntawm cov xim dub coj zaub nyob ntawm qhov zoo ntawm nws cov khoom siv hluav taws xob sab hauv. Cov tuam txhab hwm diode, xws li Nationstar, tau txais kev hwm dav dav rau kev tsim cov khoom tsaus nti -encapsulated chips nrog cov xim zoo nkauj thiab kev ua haujlwm ntev. Xyuas kom tseeb tias koj tus neeg muag khoom qhia meej meej lub npe ntawm LED diodes thiab cov qauv ntawm qhov tsis tu ncua -tam sim no tsav tsheb microchips ntawm daim ntawv spec.
Kev tswj hwm thiab kev nyab xeeb daim ntawv pov thawj
Xyuas kom meej tias cov khoom siv kho vajtse tau lees paub txog kev nyab xeeb thiab kev ua raws li ib puag ncig tsim nyog rau koj qhov chaw nyob, xws li CE (ib daim ntawv pov thawj European kev ua raws li kev noj qab haus huv, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig), FCC, lossis UL. Cov cim no ua pov thawj tias cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tau raug sim rau kev nyab xeeb ntawm hluav taws thiab hluav taws xob, uas feem ntau yuav tsum tau nruj me ntsis rau kev tuav pov hwm lub tsev.
Supplier Evaluation Matrix
Cov lus hauv qab no muaj cov txheej txheem ua tau zoo los pab pawg muab khoom qeb thiab muab qhab nia tus neeg muag khoom cov lus pom zoo thaum lub sijhawm sib tw:
| Kev ntsuas ntsuas | Cov Lus Qhia Muaj Zog | Siab - Cov Teeb Pom Kev Muaj Teeb Meem |
| Component Transparencies | Qhia meej meej cov khoom lag luam (diodes, PSUs, chips) | Siv cov lus tsis meej xws li "sab saum toj- qib kev cai Cheebtsam" |
| Cov qauv xeem | suav nrog lub Hoobkas hlawv- hauv kev sim ntawm 72+ teev | Tsis hais txog ua ntej -cov khoom xa tuaj kuaj kev tswj xyuas zoo |
| Warranty kev tiv thaiv | 2 mus rau 3 xyoos ua tiav; npog qhov chaw thiab modules | 1 xyoo txwv; cov neeg siv khoom them nyiaj txawv teb chaws shipping rau qhov chaw |
| Kev pab txhawb nqa | Muab kev txhawb nqa engineering hauv zos thiab kev pab cuam calibration | Xov tooj-tsuas yog kev txhawb nqa nrog lub sijhawm tseem ceeb- thaj tsam qeeb |
Ua tiav daim ntawv cog lus thiab kev faib khoom seem
Daim ntawv cog lus kev yuav khoom yuav tsum them ntau tshaj li qhov pib xa khoom ntawm cov khoom txee; nws yuav tsum tiv thaiv koj cov peev nyiaj rau xyoo tom ntej.
Kev Sib Tham Txog Koj Qhov Kev Pab Cuam Tshuam
Nco ntsoov xyuas kom meej tias koj daim ntawv cog lus yuav khoom zaum kawg suav nrog cov khoom tshwj xeeb ntawm batch-cov khoom seem sib phim. Cov khoom siv no yuav tsum suav nrog cov khoom siv ntxiv, cov khoom siv hluav taws xob, thiab cov ntaub ntawv sab hauv. Vim hais tias LED kev lag luam khiav tuaj yeem muaj xim kub hloov pauv me ntsis, siv cov khoom siv los ntawm cov khoom qub ua kom ntseeg tau tias txhua qhov kev kho yav tom ntej zoo li seamless thiab phim cov phab ntsa zoo kawg nkaus.
Cov lus nug nquag
Daim ntawv pov thawj CE txhais li cas ntawm daim ntawv qhia LED?
Lub cim CE (Conformité Européenne) qhia tias cov khoom ua tiav cov qauv kev noj qab haus huv, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig uas xav tau rau cov khoom siv hluav taws xob muag hauv European Economic Area, ua qhov taw qhia ntawm kev nyab xeeb engineering.
Lub Hoobkas hlawv yog dab tsi- hauv kev sim, thiab vim li cas nws tseem ceeb?
Kev kub hnyiab- hauv kev sim suav nrog kev khiav cov khoom sib sau ua ke ntawm qhov ci siab tshaj plaws rau 48 txog 72 teev tsis tu ncua ntawm qhov chaw tsim khoom. Cov kauj ruam no txheeb xyuas cov diodes tsis muaj zog lossis cov khoom sib xyaw kom lawv tuaj yeem hloov tau ua ntej lub vijtsam xa mus, txo qis ntawm - teeb meem ntawm qhov chaw.
Vim li cas kuv thiaj li yuav tsum tau batch- cov khoom seem sib xws es tsis yog tus qauv tawm -cov - txee qhov chaw?
LED ntau lawm khiav ib txwm muaj qhov sib txawv me me hauv cov xim sib npaug thiab ci ntsa iab. Yog tias koj hloov lub module xyoo tom qab nrog ib feem los ntawm cov khoom sib txawv, cov ntu tshwj xeeb yuav zoo li sov me ntsis lossis txias dua li ntawm koj cov phab ntsa video.
Dab tsi yog lub sijhawm lav rau kev lag luam sab hauv video phab ntsa?
Cov neeg muag khoom lag luam muaj npe nrov feem ntau muab kev tiv thaiv kev kho vajtse zoo txij li 2 txog 3 xyoos, uas suav nrog kev ua tsis tiav thiab kev tsim khoom tsis raug raws li cov qauv kev ua haujlwm.
