Txawm li cas los xij, tus nqi qis- cov khoom pob tshab feem ntau txiav cov ces kaum los ntawm kev siv qis dua - qib LED diodes, nyias lub rooj tsav xwm uas tsis muaj cua sov, lossis cov khoom siv hluav taws xob tsis muaj pov thawj. Kev nqis peev hauv kev lag luam - qib cov khoom siv txo qis kev pheej hmoo ntawm kev ua tsis tiav pixel ntau zaus, hloov xim, thiab lub sijhawm poob qis.
Ntsiab Technical Specifications los soj ntsuam
Thaum sib piv cov lus pom zoo ntawm cov neeg muag khoom, ua tib zoo mloog rau ntau lub hauv paus kev ntsuas uas hais txog kev ua tau zoo hauv ntiaj teb -.
Diode Hom: Nationstar vs. Lwm Hom
LED diode yog qhov tseem ceeb tshaj plaws ntawm txhua qhov screen. Premium diode hom, zoo li Nationstar, tau lees paub dav hauv kev lag luam rau lawv lub sijhawm ntev - xim ruaj khov, tsis kam ua kom sov degradation, thiab qib ci zoo ib yam dhau ntau txhiab teev. Nco ntsoov nug koj tus neeg muag khoom kom qhia meej lub npe thiab qauv ntawm LED diodes siv hauv lawv cov vaj huam sib luag.
Cov ntawv pov thawj thiab Kev Ua Raws Li Hauv Zos
Xyuas kom meej tias cov khoom siv kho mob tau lees paub txog kev nyab xeeb thiab ib puag ncig cov ntawv pov thawj tsim nyog rau koj cheeb tsam, xws li CE (ib daim ntawv pov thawj European ua tau raws li kev noj qab haus huv, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig), FCC, lossis UL. Cov ntawv pov thawj no xyuas kom meej tias cov khoom siv hluav taws xob thiab cov chips tsav tsheb tau raug kuaj ntawm nws tus kheej rau kev nyab xeeb hluav taws thiab cuam tshuam hluav taws xob.
Supplier Evaluation Framework
Cov lus hauv qab no muab cov ntawv qhia ceev ceev los pab koj ntsuas thiab ntsuas cov neeg xa khoom muaj peev xwm thaum lub sijhawm sib tw:
| Kev ntsuam xyuas qeb | High -Quality Proposal Indicators | Tsawg-Quality Proposal Risk Signals |
| Khoom Transparency | Qhia meej lub npe diode, PSU, thiab nti hom | Siv cov ntsiab lus tsis meej xws li "siab- cov khoom siv tau zoo" |
| Warranty Terms | 2 mus rau 3 xyoos ua tiav; npog qhov chaw / ua haujlwm | 1 xyoo txwv; cov neeg siv khoom them rov qab shipping ntawm qhov chaw |
| Kev Ntsuas Cov Cai | Factory hlawv -hauv kev sim ntawm 72+ teev ua ntej xa khoom | Kev kuaj tsawg kawg nkaus; nkoj ncaj qha los ntawm cov kab sib dhos |
| Cov ntaub ntawv | Muab cov ntaub ntawv CAD cov qauv thiab cov kab kos duab | Muab cov khoom lag luam dav dav daim ntawv qhia yam tsis muaj qhov tob tob |
Ua kom tiav Daim Ntawv Pom Zoo Qib Kev Muag Khoom thiab Kev Pabcuam
Daim ntawv cog lus ua tiav zoo tshaj qhov kev yuav khoom lub cev. Nws yuav tsum tsim kom muaj kev sib raug zoo ntawm kev pabcuam ntev -.
Kev Ruaj Ntseg Rau Cov Khoom Siv Hluav Taws Xob Zoo
Raws li ib feem ntawm koj daim ntawv cog lus yuav khoom, xyuas kom meej tias tus neeg muag khoom suav nrog cov khoom tshwj xeeb ntawm batch -cov khoom seem sib npaug. Cov khoom siv no yuav tsum muaj cov hlua LED ntxiv, cov khoom siv hluav taws xob, thiab cov kab hluav taws xob sab hauv. Vim tias LED kev tsim khoom sib txawv me ntsis hauv cov xim kub, qhov khoom seem xyoo dhau los ntawm txoj kev tuaj yeem ua rau cov xim tsis sib haum. Muaj batch-match spares ntawm tes zam qhov teeb meem no kiag li.
Cov lus nug nquag
Dab tsi yog "lub Hoobkas hlawv- 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 ci rau 48 txog 72 teev tas li ntawm lub Hoobkas. Qhov kev ua tau zoo no- tswj cov txheej txheem yuam kom cov khoom tsis muaj zog lossis cov pob qij txha ua tsis tau ua ntej qhov screen raug xa mus rau txawv teb chaws, tiv thaiv kev tuag- ntawm - teeb meem tuaj txog.
Lub sij hawm lav tus qauv rau kev lag luam pob tshab npo yog dab tsi?
Tus qauv kev lag luam lav rau kev lag luam muaj koob npe nrov - qib pob tshab LED kho vajtse feem ntau yog li ntawm 2 txog 3 xyoos, suav nrog cov khoom tsis xws luag thiab cov khoom siv hluav taws xob tsis ua haujlwm raws li kev ua haujlwm ib txwm muaj.
Lub cim CE txhais li cas ntawm daim ntawv qhia tshwj xeeb?
CE cim (Conformité Européenne) qhia tias cov khoom ua tau raws li qhov tseem ceeb ntawm kev noj qab haus huv, kev nyab xeeb, thiab kev tiv thaiv ib puag ncig cov qauv tsim rau cov khoom muag hauv European Economic Area, ua raws li cov qauv kev ntseeg siab rau kev tsim kev nyab xeeb.
Vim li cas nws thiaj tseem ceeb kom muaj cov khoom sib tw -cov khoom seem?
LED diodes ua nyob rau hauv txawv Hoobkas batches tuaj yeem pom me me variations nyob rau hauv cov xim hue thiab siab tshaj plaws brightness. Yog tias koj hloov lub strip tawg nrog cov khoom seem ntawm cov khoom sib txawv xyoo tom qab, cov kab xev tshwj xeeb yuav zoo li sov me ntsis lossis txias dua li cov khoom seem.
