Yini iziAma-LED e-Chip-on-Board (“COB”)?
I-Chip-on-Board noma i-“COB” ibhekisela ekufakweni kwe-chip ye-LED engenalutho lapho kuxhunywana ngokuqondile ne-substrate (njenge-silicon carbide noma isafire) ukuze kukhiqizwe ama-LED afanayo. Ama-COB LED anenani lezinzuzo kunobuchwepheshe be-LED obudala, obufana nama-LED we-Surface Mounted Device (“SMD”) noma ama-LED we-Dual In-line Package (“DIP”) . Okuphawuleka kakhulu, ubuchwepheshe be-COB buvumela ukuminyana okuphezulu kakhulu kohlu lwe-LED, noma lokho onjiniyela bokukhanya abakubiza ngokuthi “ukuminyana kwe-lumen” okuthuthukisiwe. Isibonelo, ukusebenzisa ubuchwepheshe be-COB LED kuhlelo lwesikwele esingu-10mm x 10mm kubangela ama-LED aphindwe izikhathi ezingu-38 uma kuqhathaniswa nobuchwepheshe be-DIP LED kanye nama-LED aphindwe izikhathi ezingu-8.5 uma kuqhathaniswaI-SMD LEDubuchwepheshe (bona umdwebo ngezansi). Lokhu kubangela amandla aphezulu kanye nokufana okukhulu kokukhanya. Kungenjalo, ukusebenzisa ubuchwepheshe be-COB LED kunganciphisa kakhulu ukunyathela nokusetshenziswa kwamandla kwamalungu afanayo e-LED kuyilapho kugcina okukhipha ukukhanya kungashintshi. Isibonelo, amalungu afanayo angu-500 lumen COB LED angaba mancane izikhathi eziningi futhi asebenzise amandla amancane kakhulu kune-500 lumen SMD noma i-DIP LED Array.
