Thaum nws los txog rau LEDs, muaj ob hom tseem ceeb: tsoos LEDs thiab COB LEDs. COB stands rau "chip on board" thiab hais txog qhov tseeb hais tias ntau LED chips yog mounted ncaj qha mus rau ib tug Circuit Court board es tsis txhob ntawm txhua nti yog mounted ib tug neeg. Cov thev naus laus zis no tau txais kev nyiam nyob rau xyoo tas los no, tab sis nws puas zoo dua li cov LEDs? Cia peb sib piv ob.
Brightness: COB LEDs feem ntau ci dua li cov LEDs ib txwm muaj. Qhov no yog vim ntau yam LED chips ua ke los tsim ib qho, muaj zog lub teeb ci. Qhov no txhais tau hais tias koj tuaj yeem siv tsawg dua COB LEDs kom ua tiav tib theem ntawm qhov ci ntsa iab ntau li ib txwm LEDs.
Efficiency: COB LEDs kuj feem ntau ua tau zoo dua li cov LEDs ib txwm muaj. Qhov no yog vim lawv tsim hluav taws xob tsawg, uas txhais tau hais tias tsis muaj zog tsawg. Qhov no kuj txhais tau tias COB LEDs muaj lub neej ntev dua li cov LEDs ib txwm muaj.
Tus nqi: Thaum COB LEDs muaj txiaj ntsig thiab ci dua li cov LEDs ib txwm muaj, lawv kuj tseem kim dua. Qhov no yog vim hais tias cov thev naus laus zis yuav tsum tau txuas ntau lub LED chips mus rau lub rooj tsav xwm hauv Circuit Court yog qhov nyuaj thiab kim dua. Txawm li cas los xij, tus nqi no yuav txo qis vim tias kev siv tshuab tau dav dua.
Loj: COB LEDs kuj feem ntau loj dua li cov LEDs ib txwm muaj. Qhov no tuaj yeem ua rau lawv nyuaj rau siv hauv qee cov ntawv thov uas qhov loj me yog qhov kev txhawj xeeb. Txawm li cas los xij, qhov ci ntsa iab thiab kev ua tau zoo tuaj yeem ua rau lawv tsim nyog rau qhov loj ntxiv hauv ntau qhov xwm txheej.
Hauv cov ntsiab lus, COB LEDs feem ntau zoo dua li cov LEDs ib txwm muaj nyob rau hauv cov nqe lus ntawm qhov ci thiab kev ua haujlwm. Txawm li cas los xij, lawv kim dua thiab loj dua, uas yuav ua rau lawv tsis tshua muaj txiaj ntsig rau qee yam kev siv. Thaum kawg, kev xaiv ntawm COB LEDs thiab cov tsoos LEDs yuav nyob ntawm seb qhov kev xav tau tshwj xeeb ntawm koj qhov project.
