Byombi SMD yayoboye amatara na COB yayoboye amatara arahari muri Lediant. Waba uzi itandukaniro ryabo? Reka nkubwire.
SMD ni iki? Bisobanura ibikoresho byashizwe hejuru. Uruganda rwa LED rupakira rukoresheje inzira ya SMD rukosora chip yambaye ubusa kuri bracket, ihuza amashanyarazi byombi hamwe ninsinga za zahabu, hanyuma amaherezo ikayirinda hamwe na epoxy resin.SMD ikoresha tekinoroji yo hejuru (SMT), ifite urwego rwo hejuru rwo kwikora, kandi ifite ibyiza byubunini buto, inguni nini yo gutatana, uburinganire bwiza bwa luminous, hamwe no kwizerwa cyane.
COB ni iki? Bisobanura chip ku bwato. Bitandukanye na SMD, igurisha amasaro yamatara kuri PCB, inzira ya COB ibanza gupfundika aho yashyizwe muri chip ya silicon hamwe na epoxy resin ikora neza (feza-yuzuye epoxy resin) hejuru yubutaka. Hanyuma chip ya LED ifatirwa kumurongo uhuza hamwe na kole cyangwa itayobora ikoresheje kashe cyangwa igurisha, hanyuma amaherezo guhuza amashanyarazi hagati ya chip na PCB bigerwaho no guhuza insinga (zahabu).
