Kini niChip-on-Board (“COB”) Awọn LED?
Chip-on-Board tabi “COB” n tọka si iṣagbesori ti chirún LED igboro ni olubasọrọ taara pẹlu sobusitireti (bii ohun alumọni carbide tabi oniyebiye) lati ṣe agbejade awọn akojọpọ LED. Awọn LED COB ni nọmba awọn anfani lori awọn imọ-ẹrọ LED agbalagba, gẹgẹ bi Ẹrọ Imudanu Ilẹ (“SMD”) Awọn LED tabi Awọn Ipilẹ Laini Meji (“DIP”) Awọn LED. Ni pataki julọ, imọ-ẹrọ COB ngbanilaaye fun iwuwo iṣakojọpọ ti o ga julọ ti orun LED, tabi kini awọn onisẹ ẹrọ ina tọka si bi ilọsiwaju “iwuwo lumen”. Fun apẹẹrẹ, lilo imọ-ẹrọ LED COB lori awọn abajade 10mm x 10mm square ni awọn akoko 38 diẹ sii Awọn LED akawe si imọ-ẹrọ DIP LED ati awọn akoko 8.5 diẹ sii Awọn LED akawe siSMD LEDọna ẹrọ (wo aworan atọka isalẹ). Eyi ṣe abajade kikankikan ti o ga julọ ati isokan ti ina. Ni omiiran, lilo imọ-ẹrọ COB LED le dinku ifẹsẹtẹ ati agbara agbara ti orun LED lakoko ti o tọju iṣelọpọ ina nigbagbogbo. Fun apẹẹrẹ, 500 lumen COB LED orun le jẹ igba pupọ kere si ati jẹ agbara ti o dinku pupọ ju 500 lumen SMD tabi DIP LED Array.
