COB thiab LED teeb yog ob hom teeb pom kev zoo uas tau txais kev nyiam nyob rau xyoo tas los no. Txawm hais tias lawv zoo sib xws, muaj ntau qhov sib txawv ntawm ob hom teeb pom kev zoo uas tsim nyog tshawb nrhiav.
Ua ntej, COB stands rau "chip on board", uas txhais tau hais tias ob peb LED chips yog mounted rau ib tug tib substrate los tsim ib tug module. Qhov kev tsim no tso cai rau cov qib siab dua ntawm qhov ci thiab lub zog ua haujlwm piv rau cov teeb ci LED. Ntawm qhov tod tes, LED teeb yog tsim los ntawm ntau tus neeg LED chips, uas tau teem rau hauv ib lub koob lossis kev teeb tsa sib npaug.
Qhov thib ob, COB teeb muaj lub lumen tso zis ntau dua piv rau cov teeb ci LED. Qhov no txhais tau hais tias lawv tsim lub teeb ntau dua ib watt ntawm lub zog siv, ua rau lawv muaj kev xaiv teeb pom kev zoo dua. Tsis tas li ntawd, COB teeb muaj ntau qhov sib txuam thiab xav tau qhov chaw tsawg dua li cov teeb ci LED, ua rau lawv zoo tagnrho rau cov ntawv thov nrog qhov chaw tsawg.
Thib peb, COB teeb muaj lub teeb pom kev zoo dua qub piv rau cov teeb ci LED. Qhov no yog vim muaj ntau yam LED chips mounted ntawm ib lub substrate tsim ib tug ntau txawm teeb pom kev zoo tis. Nyob rau hauv sib piv, ib txwm LED teeb yuav muaj ntau hotspots los yog tsis sib xws thaj ua rau thaj ntawm lub teeb, uas yuav muaj teeb meem rau tej yam kev siv.
Thaum kawg, COB teeb muaj lub kaum sab xis dav dua piv rau cov teeb ci LED. Qhov no txhais tau tias lawv tuaj yeem npog thaj tsam loj dua nrog tib lub teeb pom kev zoo, ua rau lawv muaj ntau yam kev xaiv rau kev siv teeb pom kev zoo.
Hauv cov ntsiab lus, thaum ob qho tib si COB thiab LED teeb yog lub zog txuag hluav taws xob thiab kev xaiv teeb pom kev ntev ntev, COB teeb muaj ntau qhov zoo dua li cov teeb ci LED. Cov no suav nrog ntau dua lumen tso zis, lub teeb zoo dua qub, thiab lub kaum sab xis dav dua. Raws li qhov tshwm sim, COB teeb tau dhau los ua qhov kev xaiv nrov dua rau ntau yam kev siv, suav nrog thaj chaw, kev lag luam, thiab teeb pom kev lag luam.
