Dab tsi yog qhov txawv ntawm SMD thiab COB LED Teeb?

Dab tsi yog qhov txawv ntawm SMD thiab COB LED teeb?

SMD

1.SMD LED nti tuaj yeem muaj txog li 3 diodes ntawm ib nti, txhua lub diode muaj qhov sib cais. Txhua lub voj voog muaj cathode thiab anode, ua rau 2, 4, lossis 6 tus neeg nyob hauv ib nti.

2.Cov nti tuaj yeem muaj cov xim liab, ntsuab, thiab xiav diode, koj tuaj yeem tsim cov xim los ntawm kev kho qhov tso zis ntau zaus.

3.Ib qhov ntau thiab tsawg tuaj yeem nqa cov chips tsim nyuaj.SMD chips paub txog lawv qhov ci, ua tau 50-100lm/w.

COB

1. COB chips feem ntau muaj 9 lossis ntau dua diodes. Nws kuj muaj 1 Circuit Court thiab 2 tus neeg sib cuag, tab sis nws tsis muaj dab tsi ua rau tus lej ntawm diodes.

2. COB LED teeb tsis tuaj yeem siv los tsim cov teeb hloov xim lossis teeb, thiab yuav tsum tau hloov kho los ntawm ntau txoj hauv kev los tsim cov xim hloov xim.

3. Txij li cov LEDs ntawm tag nrho cov teeb yog concentrated nyob rau hauv ib cheeb tsam, yuav tsum tau muaj peev xwm txias ntau dua.

   
   

Qhov zoo ntawm SMD piv rau COB

Nws tuaj yeem siv los tsim cov teeb hloov xim lossis cov teeb kom haum rau cov chips ntawm cov qauv tsim.

Muaj cov cua kub zoo dua, tsis yog qhov ntom ntom li COB chips, tawg tab sis kev sib xyaw ua ke tuaj yeem pab nthuav tawm cov cua sov ntawm cov nti mus rau lub substrate.

Txawm hais tias muaj kev ua haujlwm siab ntawm COB LED, qhov ua tau zoo ntawm SMD LED yog siab dua, nws tsim ntau dua lumens ib watt.Nws kuj ua rau lub teeb dav dua, uas txhais tau hais tias lub teeb tsis xav tau lub dab dej kub loj li COB LED.

Tus nqi ntawm SMD LEDs yuav qis dua.
