Thaum nws los txog rau LED chips, muaj ob qhov kev xaiv nrov xaiv los ntawm- SMD thiab COB. SMD stands rau Surface Mounted Device thaum COB stands rau Chip on Board. Ob leeg ntawm cov chips no muaj lawv tus kheej tshwj xeeb thiab ua haujlwm sib txawv. Cia peb nkag mus tob rau hauv lawv qhov sib txawv kom nkag siab qhov twg yog qhov zoo dua rau koj cov kev xav tau.
Brightness
Thaum nws los txog rau qhov ci, COB chips yog tus yeej meej. Lawv muaj ntau yam LED chips uas ua haujlwm ua ke kom xa cov teeb pom kev zoo dua nrog qhov dav dav. Ntawm qhov tod tes, SMD chips muaj qhov nqaim me me uas ua rau lawv tsim nyog rau kev taw qhia teeb pom kev zoo hauv cov teeb lossis teeb taws.
Loj
COB chips yog me ntsis loj dua SMD chips vim tias lawv muaj ntau yam LED chips hauv ib qho module. SMD chips, ntawm qhov tod tes, yog me me thiab ntau compact. Qhov no ua rau lawv yooj yim rau nruab rau hauv qhov chaw nruj.
Kev ua tau zoo
Ob lub chips yog lub zog txuag thiab siv zog tsawg dua li cov teeb pom kev zoo ib txwm muaj. Txawm li cas los xij, COB chips muaj zog me ntsis ntau dua li SMD chips, uas yog vim lawv qhov chaw loj dua.
Thaum tshav kub kub Dissipation
Thaum tshav kub kub dissipation yog ib qho tseem ceeb heev uas yuav tau xav txog thaum cuam tshuam nrog LED chips. COB chips zoo li kub dua SMD chips vim yog siv hluav taws xob ntau dua thiab thaj tsam loj ntawm kev tsim hluav taws xob. Qhov no txhais tau hais tias lawv xav tau cov tshuab cua txias kom zoo los tiv thaiv lawv los ntawm overheating. SMD chips, ntawm qhov tod tes, tsim kom muaj cua sov tsawg dua thiab yog li tsis tas yuav muaj cua txias ntau.
Nqi
COB chips yog kim dua SMD chips, feem ntau yog vim lawv cov brightness thiab efficiency. Txawm li cas los xij, lawv muab cov txiaj ntsig zoo dua rau cov nyiaj hauv lub sijhawm ntev vim lawv lub neej ntev thiab kev siv zog.
Xaus
Hauv kev xaus, ob qho tib si SMD thiab COB chips muaj lawv tus kheej cov yam ntxwv thiab qhov zoo thiab qhov tsis zoo. COB chips yog qhov zoo tagnrho rau cov ntawv thov uas xav tau qhov ci ntsa iab thiab dav dua, thaum SMD chips yog qhov tsim nyog rau kev taw qhia teeb pom kev zoo. Thaum kawg, kev xaiv ntawm ob lub chips no nyob ntawm koj qhov kev xav tau teeb pom kev tshwj xeeb thiab nyiaj txiag.
