Nyob rau niaj hnub no txoj kev nrhiav tau sai heev, cov qauv coj coj los hloov kho tau hloov zuj zus. LED thev naus laus zis tau hloov kho lub teeb pom kev lag luam, muab cov kev xaiv hluav taws xob muaj zog thiab ntev ntev rau cov neeg siv khoom thiab kev lag luam ib yam nkaus. Ntawm cov kev teeb tsa LED, cob (nti ntawm Board) tau tawm los ua kev xaiv zoo dua vim nws cov kev paub tseeb. Hauv tsab xov xwm no, peb yuav delve mus rau hauv cov laj thawj vim li cas COB tuav qhov kom zoo dua ntawm cov qauv siv dav dav (cov nplaim hluav taws xob. Los ntawm nws cov pa thermal qis los txhim kho kev tiv thaiv ib puag ncig, cobu tau nthuav tawm nws cov neeg sib tw.
1.SMD Vs. COB: Qhov twg zoo dua?
Thaum nws los txog rau LED tso duab thev naus laus zis, ob lub ntsiab tseem ceeb thawj lub lag luam: SMD thiab COB. Thaum lub sijhawm nto nto sib tw tau ntev mus rau kev xaiv mus rau LED teeb pom kev daws teeb meem, CAR tau tshwm sim los ua ib qho kev xaiv tsim.
Tsis zoo li SMD, uas muaj ntawm tus kheej mounted coj diodes ntawm ib qho Circuit Court Board, Cob sib xyaw ua cov chips hauv ib qho module. Qhov kev teeb tsa tshwj xeeb no tsis yog txhim kho qhov ci ci thiab kev siv lub teeb pom kev zoo tab sis kuj txo qis lub teeb pom kev ntev dua qhov deb dua. COB txoj kev txiav cov qauv sib txawv hauv cov teeb pom kev zoo nrog cov teeb pom kev zoo nrog kev sib txuam thiab xim siab.
Ii. Tsawg thermal nrog tsawg dua cua sov
Ib qho ntawm thawj qhov zoo ntawm COB Hla SMD yog nws cov kev tswj lub peev xwm zoo tshaj. COB thev naus laus zis muaj cov thermal qis vim nws cov qauv tsim kev cog lus ntau ntxiv. Lub thermal resistance txiav txim siab li cas tshav kub dissipates los ntawm LED module, ua rau COB Ntau npaum li cas ntawm kev txo cov cua sov. Qhov no ua rau tsis muaj kev txhim kho ntev thiab txo cov kev saib xyuas tab sis kuj ua kom muaj kev nyab xeeb zoo liCob Modulestsis tshua muaj zog rau overheating.
III. Kev tiv thaiv zoo heev rau kev ua kom ib puag ncig
COB ZaubMuaj kev tiv thaiv zoo heev rau ntau qhov chaw ib puag ncig, kom ntseeg tau ntev thiab kev ntseeg tau hauv ntau haiv neeg. Kho nrog epoxy cob qhia txhawm rau txhim kho kev tiv thaiv kev tiv thaiv. Nws khav theeb tsis kam rau ya raws, plua plav, zoo li qub, oxidation, thiab lub teeb xiav. Qhov kev tiv thaiv txhim kho no ua rau cov teeb pom kev zoo colutions kom muaj zog nyob rau hauv ib puag ncig nyuaj xws li thaj chaw sab nraum zoov lossis thaj chaw muaj cov av noo. Tsis tas li ntawd, COB's zoo tshaj qhov ua kom muaj oxidation kom ua kom muaj zog uas tau tuav lawv lub sijhawm ci thiab xim zoo li lawv SMS Counterparts.
IV. Tsaus nti thiab ci ua kom zoo.
Cob Technology tus architecture tsis tsuas yog txhim kho nws cov kev tswj hwm kev tiv thaiv thiab muaj peev xwm tiv thaiv nws cov teeb pom kev zoo. Vim yog cov chips sib nraus tauj ze, COB emits ib qho kev tsom xam thiab khaus heev ntawm lub teeb, ua rau tsaus ntuj nti thiab muaj kev kub ntxhov. Qhov no ua rau COB tshwj xeeb rau cov ntawv thov uas yog qhov tseeb thiab qhov zoo sib xws yog qhov tseem ceeb, xws li lub tsev khaws puav pheej, cov khw muag khoom, thiab cov khw muag khoom. Qhov teeb pom teeb ci tau muab los ntawm COB thev naus laus zis txhim kho kev pom zoo thiab pom tseeb ntawm qhov chaw pom.
Raws li lub LED teeb kev lag luam txuas ntxiv hloov zuj zus,COB thev naus laus zistau tawm los ua qhov kev xaiv tshiab thiab zoo dua rau cov coj cov kev daws teeb meem. Nws cov yam ntxwv tswv yim, xws li cov teeb hluav taws xob tsis zoo, cov pa thermal tsawg, txhim kho kev tiv thaiv ib puag ncig, thiab muaj teeb meem ci ntsa iab, ua rau nws muaj kev xaiv tsis tau. Cob tsis tsuas yog muab kev txhim kho txhim kho thiab ntev tab sis kuj tseem muaj qhov muag pom zoo dua, uas yog qhov tseem ceeb rau ntau yam kev siv.
Nrog nws cov peev xwm nce thiab nce qib hauv kev tsim cov txheej txheem,COB thev naus laus zisYog ua kom tau txais rau cov neeg siv khoom thiab kev lag luam thoob ntiaj teb. Puag COB ZaubCov kev cog lus cog lus kom muab cov khoom siv ci ntsa iab, ntau dua, thiab kev xaiv teeb pom kev zoo thaum txoj kev peb taws teeb pom peb ib puag ncig.
