LED zaub tshaj tawm xov xwm kuj muaj cov yam ntxwv ntawm kev ua haujlwm siab. Piv nrog rau kev tshaj tawm xws li TV thiab ntawv xov xwm, tus nqi ntawm LED zaub yog tus nqi qis. Cov txiaj ntsig tshwj xeeb no ua rau cov xim puv xim LED tshaj tawm kev tshaj tawm xov xwm ib txwm dhau los ua kev tshaj tawm sab nraum zoov. Sib txawv ntawm kev tshaj tawm sab nraum zoov, cov xim puv xim LED tsis yog ib qho kev tshaj tawm sab nraum zoov xwb. Nws kuj muaj cov yam ntxwv thiab qhov zoo ntawm TV thiab lwm yam xov xwm. Nws muaj qhov chaw muaj tswv yim loj dua thiab qhov chaw dav peb sab rau kev sib tham thiab kev sib txuas lus nrog cov neeg siv khoom. Nws yog daim ntawv tshuaj ntsuam tshwj xeeb uas ua tau raws li tus neeg xav tau thiab muaj lub tswv yim ntawm kev sib txuas lus hauv lub hnub nyoog digital.
coj zaub
Peb feem ntau ntsib cov teeb meem zoo li no thaum peb siv cov duab LED. LED zaub ua haujlwm ib txwm thaum pib ntawm cov khoom, tab sis tom qab lub sijhawm * yuav muaj lub teeb ci, flickering, malfunction, intermittent lub teeb, thiab lwm yam, ua rau muaj kev puas tsuaj loj rau cov khoom. Cov laj thawj rau qhov tshwm sim no yog kwv yees li hauv qab no:
1. Thaum siv cov khoom, muaj teeb meem nrog cov txheej txheem soldering, xws li kub kub, soldering lub sij hawm ntev heev, thiab tsis ua hauj lwm los tiv thaiv hluav taws xob zoo li qub. Ntau tshaj 95 feem pua ntawm cov teeb meem no tshwm sim los ntawm cov txheej txheem ntim khoom.
2, qhov zoo ntawm LED nws tus kheej los yog cov txheej txheem ntau lawm.
Txoj kev tiv thaiv
1. Ua haujlwm zoo ntawm kev tswj cov txheej txheem vuam.
2. Ua qhov kev kuaj kev laus ntawm cov khoom
Kev laus yog qhov tseem ceeb lav rau kev ntseeg siab ntawm cov khoom siv hluav taws xob, thiab nws yog qhov tseem ceeb tshaj plaws hauv kev tsim khoom. LED cov khoom tuaj yeem txhim kho kev ua tau zoo tom qab kev laus thiab pab txhawb kev ua haujlwm ruaj khov hauv kev siv tom qab. LED zaub aging test yog ib qho tseem ceeb heev nyob rau hauv kev tswj cov khoom zoo, tab sis nyob rau hauv ntau zaus nws yog feem ntau overlooked thiab tsis tuaj yeem ua kom zoo thiab muaj txiaj ntsig kev laus. Kev ntsuas kev laus ntawm LED yog qhov ntsuas ntsuas raws li cov yam ntxwv ntawm cov khoom lag luam tsis ua haujlwm tus nqi nkhaus, uas yog, lub dab da dej nkhaus, txhawm rau txhim kho kev ntseeg tau ntawm cov khoom, tab sis txoj kev no tsis tsim nyog. Tom qab tag nrho, qhov kev ntsuam xyuas kev laus txi lub neej ntawm ib qho khoom siv LED. Ntawm tus nqi.
LED txoj kev laus muaj xws li kev laus tam sim no thiab qhov hluav taws xob tsis tu ncua. Qhov chaw tam sim no tsis tu ncua txhais tau tias qhov tam sim no tsis tu ncua txhua lub sijhawm. Muaj qhov teeb meem zaus, tsis tas li tam sim no. Qhov ntawd yog alternating tam sim no los yog pulsating tam sim no. AC lossis pulsating tam sim no qhov chaw tuaj yeem tsim kom muaj txiaj ntsig zoo tas li, tab sis hom fais fab no tsis tuaj yeem hu ua qhov chaw tam sim no. Kev laus tsis tu ncua tam sim no yog tus yam ntxwv ntawm LED tam sim no ua haujlwm thiab kev tshawb fawb LED txoj kev laus; overcurrent cuam tshuam kev laus kuj yog ib txoj kev laus tshiab tau txais los ntawm LED zaub manufacturers. Hom kev laus no yog ua los ntawm kev siv qhov chaw tsis tu ncua nrog cov zaus hloov tau thiab hloov tau tam sim no. , Txhawm rau txiav txim siab qhov zoo thiab lub neej expectancy ntawm LEDs nyob rau hauv ib lub sij hawm luv luv, thiab tuaj yeem xaiv ntau qhov zais LEDs uas tsis tuaj yeem xaiv los ntawm cov qauv kev laus.
