MeneneChip-on-Board ("COB") LEDs?
Chip-on-Board ko "COB" yana nufin hawan guntu na LED danda a cikin hulɗa kai tsaye tare da ma'auni (kamar silicon carbide ko sapphire) don samar da tsarin LED. COB LEDs suna da fa'idodi da yawa akan tsoffin fasahohin LED, kamar Na'urar da aka ɗora Kwatancen (“SMD”) LEDs ko Kunshin In-line Dual (“DIP”) LEDs. Mafi mahimmanci, fasahar COB tana ba da damar haɓakar ƙira mafi girma na tsararrun LED, ko abin da injiniyoyin haske ke magana a matsayin ingantattun “yawan lumen”. Misali, ta amfani da fasahar COB LED akan sakamakon tsararriyar murabba'in 10mm x 10mm a cikin ƙarin LEDs sau 38 idan aka kwatanta da fasahar DIP LED da ƙarin LEDs sau 8.5 idan aka kwatanta da su.LED SMDfasaha (duba zane a kasa). Wannan yana haifar da mafi girma da ƙarfi da daidaituwar haske. A madadin, yin amfani da fasahar COB LED na iya rage sawun ƙafa da yawan kuzarin tsararrun LED yayin kiyaye fitowar haske akai-akai. Misali, 500 lumen COB LED tsararru na iya zama ƙarami sau da yawa kuma yana cinye ƙarancin kuzari fiye da 500 lumen SMD ko DIP LED Array.
