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. The LED nkwakọ factory iji SMD usoro fixes iferi mgbawa na bracket, electricly ejikọta abụọ na gold wires, na n'ikpeazụ na-echebe ya na epoxy resin.SMD eji elu ugwu technology (SMT), nke nwere a dịtụ elu ogo nke akpaaka, na nwere uru nke obere size, nnukwu agbasasị n'akuku, ezi luminous uniformity, na elu pụrụ ịdabere na.

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).
