ruaj khov dua, muaj teeb meem tsawg dua
1. COB sawb yog cov nti ncaj qha txuas rau FPCB, thiab tsis tuaj nrog cov hlau kub. Nyob rau hauv tsoos SMD LED strips, muaj ntau yam teeb meem yog tshwm sim los ntawm kub hlau nyob rau hauv lub LED hlaws dai. Vim hais tias cov hlau kub me me dhau, nws yog qhov ncaj ncaj kom tawg, ua rau lub nti tsis tau teeb pom kev zoo.
2. Kev tsim hluav taws xob ntawm COB sawb siv peb lub chips, ua ntej ua ke, ua ib pab pawg, tom qab ntawd hauv txhua pab pawg, thiab tom qab ntawd hauv series los ua ib kauj ruam. Txawm hais tias ib pawg ntawm ob lub chips hauv qhov tsis zoo, qhov no ib-kauj ruam sawb tuaj yeem txuas ntxiv teeb. Thiab COB ib meter ntawm chips loj npaum li cas 480, txawm tias 1-2 chips tsis teeb, yuav tsis tsim qhov tsaus ntuj, yuav tsis cuam tshuam rau kev siv. Thaum cov tsoos SMD sawb, yog CUT, tsuav yog muaj cov hlaws tsis zoo, qhov kev txiav no yuav tsis teeb, yog li yuav pom tseeb pom ib feem ntawm qhov tsaus ntuj.
