Ọdịiche dị n'etiti SMD & COB encapsulation

Ma SMD ledlight na COB ledlight dị na Lediant. Ị̀ ma ihe dị iche n’etiti ha? Ka m gwa gị.

Kedu ihe bụ SMD? Ọ pụtara n'elu mounted ngwaọrụ. Ụlọ ọrụ nkwakọ ngwaahịa LED na-eji usoro SMD na-edozi mgbawa na-adịghị na bracket, na-ejikọta ya na eriri ọla edo abụọ, ma mesịa chebe ya na epoxy resin.SMD na-eji teknụzụ elu elu (SMT), nke nwere ogo dị elu nke akpaaka, ma nwee uru nke obere nha, nnukwu akụkụ mgbasa ozi, ezigbo ihe na-egbuke egbuke, na ntụkwasị obi dị elu.

Kedu ihe bụ COB? Ọ pụtara mgbawa n'ụgbọ. N'adịghị ka SMD, nke na-ebunye bead oriọna na PCB, usoro COB na-ebu ụzọ kpuchie ebe a na-edebe ihe mgbawa silicon na resin epoxy na-eduzi (ọlaọcha-doped epoxy resin) n'elu nke mkpụrụ. Mgbe ahụ, mgbawa ikanam na-arapara na ntinye njikọ njikọ ya na gluu ma ọ bụ na-adịghị eduzi ya site na nrapado ma ọ bụ solder, na n'ikpeazụ njikọ eletrik n'etiti mgbawa na PCB na-enweta site na eriri waya (gold wire).
