He aha nāNā LED Chip-on-Board (“COB”)?
ʻO Chip-on-Board a i ʻole "COB" e pili ana i ke kau ʻana o kahi puʻupuʻu LED ʻole i pili pono me kahi substrate (e like me ka silicon carbide a i ʻole sapphire) e hana i nā ʻano LED. He nui nā pono o nā COB LED ma mua o nā ʻenehana LED kahiko, e like me nā LED Surface Mounted Device (“SMD”) a i ʻole nā ​​LED Dual In-line Package (“DIP”). ʻO ka mea nui loa, hiki i ka ʻenehana COB ke hoʻonui i ka nui o ka packing density o ka LED array, a i ʻole nā ​​​​mea ʻenehana māmā i kapa ʻia he "lumen density". No ka laʻana, me ka hoʻohana ʻana i ka ʻenehana COB LED ma kahi 10mm x 10mm square array e loaʻa i nā manawa 38 i ʻoi aku ka nui o nā LED i hoʻohālikelike ʻia me ka ʻenehana DIP LED a me 8.5 mau manawa hou aku nā LED i hoʻohālikelike ʻia me.SMD LEDʻenehana (e nānā i ke kiʻikuhi ma lalo). ʻO kēia ka hopena i ka ikaika kiʻekiʻe a me ka like ʻana o ka māmā. ʻO kahi ʻē aʻe, me ka hoʻohana ʻana i ka ʻenehana COB LED hiki ke hōʻemi nui i ka wāwae wāwae a me ka hoʻohana ʻana i ka ikehu o ka laina LED ʻoiai e mālama mau ana i ka puka māmā. No ka laʻana, hiki i ka 500 lumen COB LED array hiki ke liʻiliʻi i nā manawa he nui a hoʻopau i ka ikehu liʻiliʻi ma mua o kahi 500 lumen SMD a i ʻole DIP LED Array.
