COB Teeb yog dab tsi? Thaum twg Kuv Yuav Tsum Siv Ib Tug?
Lub teeb txuas ntxiv yog muab los ntawm COB lub teeb. Nws yog ib qho tshwj xeeb ntawm LED teeb uas koj tuaj yeem teeb tsa txhua qhov chaw kom pom cov khoom siv sij hawm. Koj tuaj yeem khaws nws hauv lub studio lossis nruab rau ntawm lub teeb ncej, lossis koj tuaj yeem nqa nrog koj. Koj tuaj yeem kho lub teeb kev taw qhia thiab kev siv lub teeb nrog COB lub teeb, thiab kev teeb tsa yuav kav ntev heev.
Nyob rau hauv qhov kev txiav txim siab, lub teeb COB yog ib lub vaj huam sib luag ntawm cov khoom ntim khoom nruj heev. Vim tias LED chips me me, tsis muaj qhov sib txawv ntawm lawv. Raws li qhov tshwm sim, lub teeb COB emits ib lub teeb sib xws, khaus ntawm lub teeb. Tsis txhob txhawj; koj tuaj yeem siv cov khoom siv los ua kom lub teeb muag muag thiab txo nws qhov hnyav.
COB txhais li cas?
Chip On Board yog lub ntsiab lus ntawm cov ntawv luv COB. Xa mus rau cov khoom ntim LED muab tso rau hauv kev sib cuag ncaj qha nrog silicon carbide lossis sapphire substrate, nws sawv cev rau kev siv tshuab tom qab COB teeb. Ntau cov LEDs tau ntim zoo ua ke ntawm thaj chaw me me ua tsaug rau COB thev naus laus zis (xws li, muaj 342 LEDs ntawm 10mm x 10mm nto).
Dab tsi txawv COB thiab LED, tshwj xeeb?
Ib qho piv txwv ntawm lub teeb LED yog lub teeb COB. Yog li ntawd, qhov sib txawv tseeb ntawm lub teeb COB thiab lwm yam LED teeb, xws li LED panels, yog nruab nrab ntawm lawv. Feem ntau, SMD (Nto Mounted Device) LED teeb yog dab tsi yog siv hauv LED vaj huam sib luag.
Lub COB lub teeb muaj qhov yooj yim circuit architecture thiab ntau diodes, uas ua rau lub teeb me me. Ib lub vaj huam sib luag LED, ntawm qhov tod tes, zoo ib yam li lub teeb me me thiab muaj tsawg dua diodes thiab ib qho kev sib txuam ntau dua circuit architecture. Tsis tas li ntawd, nws tuaj yeem hnyav dua thiab loj dua lub teeb COB.
Muaj ntau qhov kev hloov pauv sab nraud tsuas yog tsim thiab saib. Piv nrog rau SMD lub teeb, lub teeb COB yog lub zog ntau dua thiab ua kom sov. Nws tuaj yeem tsim ntau lumens thaum siv lub zog tsawg, ua rau lub teeb ci dua (xws li, COB teeb pib ntawm 80 lumens ib watt, thaum SMD teeb tsim ntawm 50 thiab 100 lumens ib watt). Tab sis tsis zoo li LED vaj huam sib luag, nws tsis tuaj yeem tsim lub teeb muaj yeeb yuj lossis hloov xim. Nyob rau hauv cov nqe lus ntawm cov xim kub, SMD teeb yog ntau adaptable.
Lub teeb SMD tuaj yeem siv los ua lub teeb pom kev zoo vim nws ci ntsa iab los ntawm txhua lub kaum ntse ntse. Txawm li cas los xij, lub teeb COB ua haujlwm zoo dua li lub teeb saum toj kawg nkaus kom pom cov ntsiab lus lossis saum npoo ntawm sab saud vim nws muab lub teeb pom kev zoo ib yam.
