Cov hauv qab no yog cov lus qhia ntxaws ntxaws rau kev laus xeem ntawm LED Daim iav Teeb:
Cheebtsam hluav taws xob (xws li coj cov hlaws dai, lub vaj muaj roj cape (xws li cov khoom siv nplaum, thiab cov khoom siv tsis zoo) muaj qee lub sijhawm siv sijhawm thawj zaug (thaum lub sijhawm ua haujlwm tsis tiav). Kev kuaj mob laus tuaj yeem kho kom nrawm nrawm ntawm cov 'no cov khoom lag luam tsis txaus' cov khoom lag luam thiab tiv thaiv lawv kom tsis txhob ua lag luam.
Thaum lub sij hawm thawj theem teeb pom kev zoo xws li cov nyom flux, xim kub, thiab cov xim kub, thiab tsav lub zog ua rau hloov pauv me me (drift). Kev laus yuav pab ua kom ruaj khov cov kab no.
Kev ua haujlwm txuas ntxiv yuav tsim cov cua sov. Kev kuaj mob laus tuaj yeem txheeb xyuas qhov ua tau zoo ntawm cov qauv cua sov dissptation, zam kev ua kom nrawm nrawm, thiab muaj kev nyab xeeb rau kev kub ntxhov los ntawm kev kub ntxhov.
Cov teeb meem xws li cuav soldering, txias soldering, kev sib sau ua ke, thiab kev sib dhos ua ke kuj yuav raug nthuav tawm nyob rau hauv lub zog ntev {}} ntawm thiab kub nce mus.
Lub zog tsav tsheb fais fab yog qhov tseem ceeb ntawm LED teeb. Kev ntsuam xyuas cov laus tuaj yeem kuaj tau nws qhov ruaj khov, kev ua tau zoo, ntsuas kub thiab kev tawm tsam rau voltage hloov pauv thaum ntev}} kev ua haujlwm.
Los ntawm tshem tawm cov khoom puas, cuam tshuam ntau dua kom cov nyiaj rov qab thiab kev tsis txaus siab ntawm cov khoom lag luam, thiab txhim kho hom koob npe.
Txawm hais tias muaj ntau tus qauv kev nyab xeeb (xws li UL, CE, CCC, muaj kev cia siab xav tau kev xav tau kom tau ua kom muaj kev txheeb xyuas kev laus.
Cov ntsiab lus tseem ceeb / cov khoom siv ntawm cov laus
Nruam teeb pom kev
- Txoj kev: Nruab / muab lub iav teeb ntawm cov txheej txheem qub thiab hauv ib hom kev sib txuas lus (lossis ua kom muaj kev ntsuas hluav taws xob.
- Lub sijhawm: nws feem ntau yuav txawv ntawm 12 teev, 24 teev, 48 teev rau txawm 72 teev. Lub sijhawm nyob ntawm qhov nyuaj ntawm cov khoom lag luam, tus nqi, yuav tsum tau ua haujlwm thiab cov ntaub ntawv keeb kwm. Ntau txoj hlua khi los yog siab -}}}}}}}}}}}}}}}} {kawg cov khoom yuav xaiv rau lub sijhawm ntev dua.
- Soj ntsuam: Tshawb xyuas qhov LED lub teeb taws / cov hlua muaj cov teeb tuag, thaj chaw tsaus, flickering, lossis tsis xwm yeem xim. Kuaj xyuas yog tias lub zog tsav hluav taws xob yog kub tsis meej, ua cov suab nrov txawv txawv lossis haus luam yeeb. Kuaj xyuas yog tias muaj kev yellowing, delamination lossis bubbling ntawm lub hlws ris ntawm daim iav nto thiab lub teeb sawb. Seb qhov kov kov yog rhiab thiab txhim khu kev qha; Txawm hais tias lub furogging muaj nuj nqi (yog tias muaj) pib thiab nres ib txwm.
Kev Kuaj Mus Ncig
- Txoj kev: Simulate siv cov xwm txheej siv uas cov neeg uas cov neeg nquag hloov ntawm thiab tawm. Teem lub tshuab ua tsis zoo no feem pua ntawm / tawm (xws li nyob rau 1 feeb thiab tom qab ntawd tawm rau 30 feeb thiab tom qab ntawd nws puas ntau pua lossis txawm tias ntau txhiab zaus.
- Lub Hom Phiaj: Feem ntau los sim qhov pib ntawm lub zog tsav tau, raws li cov neeg kho tshuab thiab hluav taws xob ua, thiab tswj hwm hluav taws xob. Nquag zog rau thiab tawm muaj ib qho cuam tshuam tseem ceeb rau cov khoom siv hluav taws xob.
High -}} kub kev kub ntxhov
- Txoj Kev: Ua cov teeb pom kev txuas ntxiv lossis ntawm - tawm ntawm chav kawm nyob rau hauv chav laus lossis lwm yam kub nyob rau qib 40- 55 degree, lossis siab dua).
- Lub Hom Phiaj: Txhawm rau ua kom nrawm nrawm ntawm cov khoom siv thiab ntau dua kev ntsuas qhov ua tau zoo ntawm cov cua sov dissipation tsim. Kev kub siab yuav ua kom muaj qhov tsis zoo ntawm cov khoom siv xws li cov hluav taws xob hluav taws xob thiab ua kom yooj yim rau cov kev sib tsoo (xws li cov khoom sib tsoo) kom raug. Rau daim iav teeb txawb siv hauv chav dej, nws yog ib qho tshwj xeeb rau simulate qhov siab {}} av noo ib puag ncig hauv lub caij ntuj sov lossis tom qab da dej.
Voltage Fononupress Tso Cai
- Txoj kev: Thaum lub sijhawm laus, txhob txwm cia cov lus qhia voltage los hloov pauv tsis pub dhau lossis sab nraud tus nqi (xws li dav dua).
- Lub Hom Phiaj: Txhawm rau ntsuas qhov yoog kom haum rau cov phiaj xwm tsis ruaj khov, thiab txiav txim siab seb puas yuav flicker, tawm mus vim yog kev hloov pauv ntawm voltage hloov.
Tshuaj xyuas thiab txiav txim siab tom qab kev sim siab
Tom qab kev xeem laus tiav lawm, nws tsis tau ntim ncaj qha. Cov kauj ruam tseem ceeb hauv qab no tseem yuav tsum tau ua
Kev Saib Xyuas Kev Pom
Ua tib zoo soj ntsuam daim iav saum npoo av, lub tsev txawb vaj tsev, thiab teeb sawb rau tej yam tsis txaus ntseeg, kev sib tsoo, av puas, thiab lwm yam, thiab lwm yam.
Kev them nyiaj ntawm cov photielectric
Piv nrog rau cov ntaub ntawv pib ua ntej kev laus thiab ntsuas cov tsis tseem ceeb
Seb puas luminous flux (lumen tus nqi), xim kub thiab xim rendering index yog nyob rau hauv cov nominal ntau thiab tsis muaj qhov pom tseeb. Cov khoom sib thooj xim (seb muaj xim sib txawv lossis thaj ua rau thaj). Cov hwj chim tawm, muaj hwj chim siv zog, ua tau zoo.
Ua Haujlwm Rov Qab
Rov {{-} Ua haujlwm tag nrho cov pob hluav taws xob, kev hloov xim kub, kev pom zoo, kev ua haujlwm kom ntseeg tau tias txhua yam yog qhov qub.
Kev Ntsuam Xyuas Kev Nyab Xeeb
Ntsuas seb qhov ntsuas kub nce ntawm ntu tseem ceeb (xws li LED lub teeb Panels, tsav hluav taws xob muab cov ntaub thaiv, thiab lub davhlau ya nyob twg) yog nyob rau hauv kev nyab xeeb. Ua cov rwb thaiv tsev uas tsim nyog thiab tiv thaiv voltage kuaj.
Suab nrov txawv thiab tsw ntxhiab
Mloog cov suab nrov txawv txav thaum lub zog -}} ntawm thiab kev ua haujlwm, thiab tsw rau tej yam hlawv lossis lwm yam tsw ntxhiab.
Kev txiav txim
Raws li kev tshuaj xyuas cov txiaj ntsig thiab cov qauv preset, txiav txim siab seb puas muaj cov khoom lag luam tsim nyog. Yog tias qhov taw qhia tseem ceeb (xws li muaj lub teeb tuag, ua haujlwm tsis tiav, nws yuav tsis raug txiav txim siab, nws yuav tau kho cov khoom lag luam thiab xav tau kho lossis raug kaw.
