A cikin saurin ci gaban fasaha na yau, hanyoyin nunin LED sun samo asali sosai.Fasahar LED ta kawo sauyi ga masana'antar hasken wuta, tana samar da ingantaccen makamashi da zaɓuɓɓuka masu dorewa ga masu amfani da kasuwanci iri ɗaya.Daga cikin saitunan LED daban-daban, COB (Chip on Board) ya fito a matsayin babban zaɓi saboda halayen fasaha.A cikin wannan labarin, zamu shiga cikin dalilan da yasa COB ke da fa'ida akan fasahar SMD (Surface Mount Device).Daga ƙarancin iskar zafi zuwa ingantacciyar kariya daga abubuwan muhalli, COB da gaske ya zarce masu fafatawa.
1.SMD vs. COB: Wanne Yafi?
Idan ya zo ga fasahar nunin LED, manyan masu fafutuka biyu sun mamaye kasuwa: SMD da COB.Yayin da Na'urar Dutsen Surface ya daɗe shine zaɓi-zuwa zaɓi don mafita na hasken LED, COB ya fito a matsayin babban madadin.
Ba kamar SMD ba, wanda ya ƙunshi diodes ɗin LED masu ɗaiɗaiku akan allon kewayawa, COB yana haɗa kwakwalwan LED masu yawa a cikin tsari guda.Wannan ƙayyadaddun ƙayyadaddun tsari ba kawai yana haɓaka haske da ƙarfin hasken ba amma kuma yana rage girman hasken a cikin nesa mai nisa.Zane-zane na COB yana haifar da fitowar haske mara kyau tare da daidaituwa da ma'anar launi mai girma.
