Dukansu SMD LED downlight da COB LED downlight suna samuwa a cikin Lediant. Kun san bambancin da ke tsakaninsu? Bari in gaya muku.
Menene SMD? Yana nufin na'urori masu hawa sama. The LED marufi factory ta amfani da SMD tsari gyara danda guntu a kan sashi, electrically haɗa biyu da zinariya wayoyi, kuma a karshe kare shi da epoxy resin.SMD yana amfani da surface Dutsen fasaha (SMT), wanda yana da in mun gwada da high mataki na aiki da kai. kuma yana da abũbuwan amfãni daga ƙananan girman, babban kusurwar watsawa, kyakkyawar daidaituwa mai haske, da babban aminci.
Menene COB? Yana nufin guntu a kan jirgin. Ba kamar SMD ba, wanda ke siyar da bead ɗin fitilar zuwa PCB, tsarin COB ya fara rufe wurin sanya guntun siliki tare da resin epoxy mai ɗaukar zafi (zurfin-doped epoxy resin) a saman ma'aunin. Sa'an nan kuma LED guntu a manne da interconnection substrate tare da conductive ko non conductive manne ta m ko solder, kuma a karshe da wutar lantarki interconnection tsakanin guntu da PCB an gane ta hanyar waya (gold waya) bonding.
