Lub ntsiab lus ntawm COB txhais tau tias "Chip on board". Qhov txawv ntawm COB LEDs thiab SMD LEDs yog tias lawv muaj ntau diode. COB LEDs feem ntau muaj 9 lossis ntau dua diodes.
Monochromatic tus qauv COB LED chips muaj 2 hu. Nws yog nquag siv vim lub vaj huam sib luag zoo li lub teeb ntawm COB LED thiab qhov yooj yim Circuit Court yuav tsum tau. COB LEDs tuaj yeem ua kom pom qhov ua tau zoo ntawm kev ua haujlwm txias ua tsaug rau cov ceramic substrate. COB LEDs yog qhov zoo dua rau cov zis siab lumen hauv cov teeb pom kev nyab xeeb thiab tsom teeb.
Piv txwv li; Thaum tsim 50W LED dej nyab teeb, koj yuav tsum siv ntau ntau SMD LEDs. Hloov chaw, nws yuav txaus siv ib qho 50W COB LED ntsuas 28 x 28 mm.
