ʻO ka mea mua, pono e loaʻa kahi ʻike kumu o nā LED mount mount device (SMD). ʻO ia nā LED i hoʻohana pinepine ʻia i kēia manawa. Ma muli o ko lākou maʻalahi, ua hoʻopili paʻa ʻia nā pahu LED i nā papa kaapuni i paʻi ʻia a hoʻohana nui ʻia i nā kukui hoʻolaha kelepona. ʻO kekahi o nā hiʻohiʻona kaulana loa o ka SMD LED chips ka helu o nā pilina a me nā diodes.
Ma kahi pahu SMD LED, hiki ke ʻoi aku ma mua o ʻelua mau pilina. Hiki ke loaʻa a hiki i ʻekolu diodes me nā kaapuni kūʻokoʻa ma kahi pahu hoʻokahi. Loaʻa i kēlā me kēia kaapuni kahi anode a me kahi cathode, ka hopena i 2, 4, a i ʻole 6 mau pilina ma ka chip.
Nā ʻokoʻa ma waena o nā LED COB a me nā LED SMD
Ma kahi pahu SMD LED hoʻokahi, hiki ke piʻi i ʻekolu diodes, kēlā me kēia me kāna kaapuni ponoʻī. ʻO kēlā me kēia kaapuni i loko o ia chip he cathode a me kahi anode, ka hopena i 2, 4, a i ʻole 6 mau pilina. ʻEiwa a ʻoi aʻe paha nā diodes i nā chips COB. Eia kekahi, ʻelua mau pilina a me hoʻokahi kaapuni COB me ka nānā ʻole i ka helu o nā diodes. Ma muli o kēia hoʻolālā kaapuni maʻalahi, ʻike ʻia nā kukui COB LED e like me ka panel, aʻo nā kukui SMD LED e like me kahi hui o nā kukui liʻiliʻi.
Hiki ke noho nā diodes ʻulaʻula, ʻōmaʻomaʻo, a me polū ma kahi pahu SMD LED. Ma ka hoʻololi ʻana i nā pae puka o nā diodes ʻekolu, hiki iā ʻoe ke hana i kekahi hue. Ma kahi kukui LED COB, ʻelua wale nō mea pili a me kahi kaapuni. ʻAʻole hiki ke hana i ke kukui hoʻololi kala a i ʻole ke kukui me lākou. Pono ka hoʻoponopono ʻana i nā ʻano he nui no ka loaʻa ʻana o kahi hopena hoʻololi kala. No laila, hana maikaʻi nā kukui COB LED i nā noi e koi ana i hoʻokahi hue ma mua o nā kala he nui.
Ua ʻike maikaʻi ʻia ka ʻōlinolino o nā chips SMD he 50 a 100 lumens i kēlā me kēia watt. Ua ʻike ʻia ʻo COB no kāna ʻoihana wela kiʻekiʻe a me ka ratio lumen per watt. Inā he 80 lumens ka liʻiliʻi o ka pahu COB i kēlā me kēia watt, hiki iā ia ke hoʻokuʻu i nā lumens me ka liʻiliʻi o ka uila. Hiki ke hoʻohana ʻia i loko o nā ʻano puʻupuʻu like ʻole a me nā mea hana, e like me ka uila kelepona paʻalima a i ʻole nā pahu kiʻi kiko-a-pana.
Ma waho aʻe o kēia, koi ʻo SMD LED chips i kahi kumu ikehu waho liʻiliʻi, ʻoiai ʻo COB LED chips e koi i kahi kumu ikehu o waho.
