Gịnị bụIgwe ọkụ mgbawa (“COB”)?
Chip-on-Board ma ọ bụ "COB" na-ezo aka na nrịgo nke mgbawa ọkụ ọkụ na kọntaktị kpọmkwem na mkpụrụ (dị ka silicon carbide ma ọ bụ sapphire) iji mepụta ọkụ ọkụ. Igwe ọkụ COB nwere ọtụtụ uru karịa teknụzụ LED ochie, dị ka igwe gbara agba (“SMD”) LED ma ọ bụ ngwugwu Dual In-line (“DIP”) LEDs. Karịsịa, teknụzụ COB na-enye ohere maka njupụta dị elu nke ngwugwu LED, ma ọ bụ ihe ndị injinia ọkụ na-ezo aka dị ka “njupụta lumen” ka mma. Dịka ọmụmaatụ, iji teknụzụ COB LED na 10mm x 10mm square array results na 38 ugboro karịa LEDs tụnyere teknụzụ DIP LED na 8.5 ugboro karịa LEDs tụnyere.SMD LEDteknụzụ (lee eserese n'okpuru). Nke a na-ebute oke ike na oke nha nke ìhè. N'aka nke ọzọ, iji teknụzụ COB LED nwere ike ibelata akara ukwu na ike ike nke nrụnye ọkụ ka ọ na-edobe mmepụta ọkụ mgbe niile. Dịka ọmụmaatụ, 500 lumen COB LED array nwere ike ịdị ntakịrị karịa ma na-eri obere ume karịa 500 lumen SMD ma ọ bụ DIP LED Array.
