Kuv tau nyob hauv kev lag luam txawv teb chaws tau ntau xyoo, thiab ib lo lus nug cov neeg siv khoom nug kuv txhua lub sijhawm yog: thaum xaiv tus neeg muag khoom LED txoj kev teeb, cov ntawv pov thawj twg tseem ceeb? Ua siab ncaj, nws yog ib lo lus nug zoo, vim tias cov ntawv pov thawj yog yam uas tsis muaj leej twg xav txog kom txog thaum muaj ib yam dab tsi mus tsis ncaj ncees lawm - thiab tom qab ntawd lawv yog qhov tseeb txiav txim siab seb koj cov khoom xa tuaj tshem tawm kev lis kev cai lossis dhau ntawm tus neeg siv khoom kuaj xyuas. Cia peb taug kev los ntawm cov ntawv pov thawj uas tuaj ntau zaus.
Cia peb pib nrog qhov yooj yim tshaj plaws: daim ntawv pov thawj CE. Qhov no yog qhov yuav tsum tau ua rau EU ua lag luam - yam tsis muaj nws, LED txoj kev teeb yeej tsis tuaj yeem nkag mus rau Tebchaws Europe. Tab sis ntawm no yog qhov ntes: ob peb lub tuam txhab me me muaj daim ntawv pov thawj CE uas tau yuav lossis qiv, thiab yog tias muaj qee yam tsis raug, cov ntawv pov thawj yuav tsis tuav. Thaum kuaj xyuas tus neeg xa khoom, nco ntsoov nug tus lej pov thawj thiab txheeb xyuas lub cev tawm koj tus kheej hauv online.
Qhov thib ob yog RoHS ntawv pov thawj. Hauv cov ntsiab lus yooj yim, nws txwv tsis pub muaj cov khoom phom sij, thiab nws tseem ceeb tsis yog hauv EU nkaus xwb tab sis nce hauv thaj chaw ntawm Middle East thiab Southeast Asia ib yam nkaus. Cov khoom lag luam uas tsis ua raws li RoHS cov qauv yog lub sijhawm ntev - lub sijhawm lav txawm tias pheej yig npaum li cas nws yog - tsoomfwv thiab loj- cov phiaj xwm loj hauv qhov tshwj xeeb yuav luag txhua zaus xav tau cov ntawv xeem rau qhov no.
Thib peb, CB daim ntawv pov thawj. Ntau tus neeg siv khoom tsis paub txog qhov no, tab sis yog tias koj muag teeb pom kev hauv ntau lub tebchaws, daim ntawv pov thawj CB tuaj yeem txuag koj lub sijhawm tseem ceeb thiab raug nqi rau daim ntawv pov thawj rov qab. Nws yog ib feem tseem ceeb ntawm kev sib koom ua ke thoob ntiaj teb - kev lees paub.
Plaub, LM80 thiab TM21 qhia. Ob qhov kev ntsuam xyuas no yog tshwj xeeb rau cov teeb pom kev zoo ntawm LED thiab cuam tshuam ncaj qha rau seb lub teeb yuav tseem tuav nws qhov ci tom qab siv ntau xyoo. Lub chaw tsim hluav taws xob LED txoj kev raug cai yuav tsum muaj peev xwm tsim tau ob daim ntawv tshaj tawm - yog tias lawv ua tsis tau, nws tsim nyog yuav tsum ceev faj txog. Fixtures nrog lub teeb nrawm nrawm feem ntau yuav tsum tau hloov hauv qis dua ob xyoos.
Thib tsib, ntsev- tshuaj tsuag thiab vibration test report. Qhov no tau raug saib xyuas ntau, tab sis nws tseem ceeb tshwj xeeb tshaj yog rau cov cheeb tsam ntug hiav txwv lossis cov chaw ua si hauv chaw ua haujlwm. Ntsev- tshuaj tsuag tshuaj ntsuas kev tiv thaiv corrosion, thiab kev vibration test ntsuas kev ruaj ntseg - ob qho tib si tshwj xeeb rau cov haujlwm nyob ze cov chaw tsim khoom lossis cov chaw nres nkoj, thiab cov ntawv ceeb toom no tuaj yeem txuag koj ntau ntawm kev saib xyuas mob taub hau hauv txoj kev.
Ib qho ntxiv uas tsim nyog hais: daim ntawv pov thawj tsis yog hais txog seb puas muaj cov ntaub ntawv muaj nyob - nws kuj yuav tsum tau ua raws li tus qauv uas koj tab tom yuav. Qee tus neeg xa khoom xa daim ntawv pov thawj rau cov qauv sib txawv los sau qhov sib txawv; yog tias tus qauv tsis sib xws, daim ntawv pov thawj tseem ceeb tsis muaj nqis. Ua ntej kev yuav khoom, muaj cov ntawv pov thawj sib tw rau cov khoom lag luam kab los ntawm kab, thiab xa cov ntaub ntawv no mus rau daim ntawv cog lus kom tsis muaj kev sib cav tom qab.
Kuj tseem muaj qee yam yooj yim tsis nco: cov ntawv pov thawj muaj hnub tas sij hawm. CE thiab RoHS daim ntawv pov thawj feem ntau xav tau kev rov ua dua tshiab txhua ob peb xyoos, thiab qee tus neeg muag khoom tseem tuav daim ntawv pov thawj xyoo dhau los rau cov khoom lag luam uas tau hloov kho ntev dua - txhais tau tias daim ntawv pov thawj tsis phim cov khoom tiag. Ua kom nws tus cwj pwm los xyuas hnub siv tau ua ntej kos npe rau ib yam dab tsi. Nws yog ib kauj ruam ntxiv me me, tab sis nws tuaj yeem cawm koj ntau yam teeb meem tom qab.
Cov kev cai ntawv pov thawj kuj txawv ntawm kev ua lag luam. Kev xa tawm mus rau North America, piv txwv li, yuav xav tau UL lossis DLC ntawv pov thawj; xa tawm mus rau qhov chaw ntawm Middle East, SASO ntawv pov thawj feem ntau tsis tuaj yeem zam. Yog li ua ntej xaiv tus neeg muag khoom LED txoj kev teeb pom kev zoo, nws yog qhov zoo tshaj rau ntsia koj lub hom phiaj ua lag luam ua ntej, tom qab ntawd ua haujlwm rov qab los xyuas seb cov ntawv pov thawj twg koj xav tau - es tsis pom cov ntaub ntawv ploj tom qab cov khoom tau npaj xa tuaj, uas tsuas yog ncua sij hawm xa tuaj.
Hauv kev lag luam txawv teb chaws, ntawv pov thawj tsis yog lub thawv -ticking ce - nws yog kev tiv thaiv tiag tiag. Thaum xaiv tus neeg muag khoom LED txoj kev teeb, tsis txhob sib piv cov nqi. Tau txais daim ntawv pov thawj txheeb xyuas ua ntej, thiab lwm qhov kev sib koom tes yuav mus zoo dua. Yog tias koj tab tom ua haujlwm nrog LED txoj kev teeb pom kev zoo tam sim no thiab tsis paub tseeb tias cov ntaub ntawv pov thawj koj muaj tiav lossis siv tau tiag tiag, xav tias dawb mus cuag tau txhua lub sijhawm. Kuv tuaj yeem pab koj txheeb xyuas txhua yam kab los ntawm kab, yog li koj tsis txhob muaj qhov cuam tshuam thiab ua haujlwm nrog tus neeg muag khoom koj tuaj yeem ntseeg tau.
