Ob leeg SMD coj downlight thiab COB coj downlight muaj nyob rau hauv Lediant. Koj puas paub qhov txawv ntawm lawv? Cia kuv qhia koj.
SMD yog dab tsi? Nws txhais tau tias nto mounted li. Lub Hoobkas ntim LED siv cov txheej txheem SMD kho cov pob liab qab ntawm lub bracket, hluav taws xob txuas ob lub xov hlau kub, thiab thaum kawg tiv thaiv nws nrog epoxy resin.SMD siv cov tshuab nto mount (SMT), uas muaj cov qib siab ntawm automation, thiab muaj qhov zoo ntawm qhov me me, loj tawg lub kaum sab xis, zoo luminous uniformity, thiab muaj kev ntseeg siab.
COB yog dab tsi? Nws txhais tau tias chip on board. Tsis zoo li SMD, uas solders lub teeb hlaws rau PCB, cov txheej txheem COB thawj zaug npog qhov chaw tso rau ntawm silicon nti nrog thermally conductive epoxy resin (silver-doped epoxy resin) nyob rau saum npoo ntawm substrate. Tom qab ntawd cov nti LED tau ua raws li kev sib txuas ntawm lub substrate nrog conductive lossis non-conductive kua nplaum los ntawm cov nplaum los yog solder, thiab thaum kawg cov hluav taws xob sib txuas ntawm cov nti thiab PCB tau paub los ntawm cov hlau (kub hlau) kev sib txuas.
