Nyob rau niaj hnub no txoj kev nce toj kev yees duab sai sai, LED zaub daws teeb meem tau hloov zuj zus.LED thev naus laus zis tau hloov pauv kev lag luam teeb pom kev zoo, muab cov kev xaiv txuag hluav taws xob thiab kav ntev rau cov neeg siv khoom thiab cov lag luam ib yam nkaus.Ntawm cov kev teeb tsa LED ntau yam, COB (Chip on Board) tau tshwm sim los ua qhov kev xaiv zoo tshaj vim nws cov yam ntxwv.Nyob rau hauv tsab xov xwm no, peb yuav delve rau hauv cov laj thawj vim li cas COB tuav qhov zoo dua li siv dav siv SMD (Nto Mount Device) thev naus laus zis.Los ntawm nws cov thermal emissions tsawg los txhim kho kev tiv thaiv ib puag ncig, COB tiag tiag outshines nws cov neeg sib tw.
1.SMD vs. COB: Qhov twg zoo dua?
Thaum nws los txog rau LED zaub technology, ob lub ntsiab contenders ua lag luam: SMD thiab COB.Thaum Nto Mount Device tau ntev tau mus rau kev xaiv rau LED teeb pom kev zoo, COB tau tshwm sim los ua lwm txoj hauv kev.
Tsis zoo li SMD, uas muaj ib tus zuj zus mounted LED diodes ntawm lub rooj tsavxwm Circuit Court, COB suav nrog ntau lub LED chips hauv ib qho module.Qhov kev teeb tsa tshwj xeeb no tsis yog tsuas yog txhim kho qhov ci ntsa iab thiab kev siv ntawm lub teeb pom kev zoo tab sis kuj txo qis lub teeb lub attenuation nyob rau qhov ntev ntev.COB qhov kev txiav-ntug tsim tau ua rau lub teeb pom kev tsis sib haum xeeb nrog kev sib luag thiab kev ua kom xim siab.
II.Tsawg Thermal nrog tsawg tshav kub
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm COB tshaj SMD yog nws cov peev txheej thermal tswj tau zoo dua.COB thev naus laus zis muaj qis thermal kuj vim nws cov qauv tsim ntau dua.Lub thermal tsis kam txiav txim siab li cas cov cua kub dissipates los ntawm LED module, ua COB ntau npaum li cas ntawm kev txo cov cua sov buildup.Qhov no ua rau tsis yog tsuas yog txhim kho lub neej ntev thiab txo kev saib xyuas tab sis kuj txhim kho kev nyab xeeb raws liCOB modulestsis tshua muaj overheating.
III.Kev tiv thaiv zoo tiv thaiv ib puag ncig Factors
COB zaubmuaj kev tiv thaiv zoo heev tiv thaiv ntau yam ib puag ncig, ua kom muaj kev ruaj khov thiab kev ntseeg siab hauv ntau yam xwm txheej.Kho nrog epoxy resin los txhim kho kev tiv thaiv kev ua haujlwm.Nws boasts superior tsis kam mus ya raws, plua plav, zoo li qub, oxidation, thiab xiav lub teeb.Qhov kev tiv thaiv zoo no ua rau COB teeb pom kev zoo daws teeb meem kom muaj kev vam meej hauv qhov chaw nyuaj xws li chaw sab nraum zoov lossis thaj chaw uas muaj av noo siab.Tsis tas li ntawd, COB qhov kev tiv thaiv zoo tshaj rau oxidation ua kom cov LEDs khaws lawv qhov ci thiab xim raug nyob rau lub sijhawm ntev, tsis zoo li lawv cov SMD counterparts.
IV.Darker thiab Sharper zoo.
COB thev naus laus zis thev naus laus zis tsis yog tsuas yog txhim kho nws cov kev tswj hwm thermal thiab kev tiv thaiv lub peev xwm tab sis kuj tseem txhawb nqa nws cov teeb pom kev zoo.Vim yog qhov sib ze ntawm LED chips, COB emits lub teeb pom kev zoo dua thiab khaus ntawm lub teeb, ua rau cov duab ntxoov ntxoo tsaus dua thiab nthuav dav.Qhov no ua rau COB tshwj xeeb tshaj yog rau cov ntawv thov uas qhov tseeb thiab qhov sib txawv siab yog qhov tseem ceeb, xws li tsev cia puav pheej, khw muag khoom, thiab chav ua yeeb yam.Lub teeb pom kev zoo dua los ntawm COB thev naus laus zis txhim kho qhov pom kev pom thiab pom tseeb ntawm qhov chaw teeb pom kev zoo.
Raws li kev lag luam LED Display txuas ntxiv mus,COB technologytau tshwm sim los ua ib qho kev xaiv tshiab thiab zoo tshaj rau LED zaub daws teeb meem.Nws cov yam ntxwv kev, xws li cov teeb pom kev zoo, tsis tshua muaj thermal emissions, txhim khu kev tiv thaiv ib puag ncig, thiab teeb pom kev zoo, ua rau nws muaj kev xaiv tsis zoo.COB tsis tsuas yog muab kev txhim kho kev ua tau zoo thiab lub neej ntev, tab sis kuj muaj qhov pom kev zoo dua qub, uas yog qhov tseem ceeb rau ntau yam kev siv.
Nrog nws cov koob meej thiab kev nce qib hauv kev tsim khoom,COB technologytau dhau los ua tau yooj yim rau cov neeg siv khoom thiab cov lag luam thoob ntiaj teb.puag COB zaubcov kev daws teeb meem cog lus tias yuav xa cov teeb pom kev zoo dua, muaj txiaj ntsig zoo dua, thiab kev xaiv teeb pom kev ntev dua thaum hloov pauv txoj kev uas peb teeb pom kev nyob ib puag ncig.
