He aha nā ʻokoʻa ma waena o LED maʻamau a me COB LED?

No ka hoʻomaka ʻana, pono e loaʻa ka ʻike kumu o nā LED Surface-Mounted Device (SMD). ʻAʻole kānalua lākou i nā LED i hoʻohana pinepine ʻia i kēia manawa. Ma muli o kona maʻalahi, ʻoiai ma ke kukui hoʻolaha kelepona, ua hoʻopili paʻa ʻia ka chip LED i kahi papa kaapuni paʻi a hoʻohana nui ʻia. ʻO kekahi o nā hiʻohiʻona ʻokoʻa loa o nā pahu SMD LED ʻo ka helu o nā pilina a me nā diodes.
Ma nā ʻāpana SMD LED, hiki ke loaʻa i ʻelua mau pilina. Hiki ke ʻike ʻia a hiki i ʻekolu diodes me nā kaapuni pākahi ma kahi pahu hoʻokahi. Loaʻa i kēlā me kēia kaapuni kahi anode a me kahi cathode, e loaʻa ai ka 2, 4, a i ʻole 6 mau pilina ma kahi pahu.

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 kahi chip o kēia ʻano he hoʻokahi cathode a me hoʻokahi anode, e loaʻa ana i 2, 4, a i ʻole 6 mau pilina. ʻEiwa mau diodes a ʻoi aku paha nā pahu COB. Eia kekahi, ʻelua mau pilina a me hoʻokahi kaapuni nā pahu COB me ka nānā ʻole i ka nui o nā diodes. Ma muli o kēia hoʻolālā kaʻapuni maʻalahi, ʻike ʻia nā kukui COB LED e like me ka panel, aʻo nā kukui SMD LED e ʻike ʻia he ʻohi kukui liʻiliʻi.

Hiki ke loaʻa kahi diode ʻulaʻula, ʻōmaʻomaʻo, a me ka uliuli ma ka chip SMD LED. Ma ka hoʻololi ʻana i ka pae puka o nā diodes ʻekolu, hiki iā ʻoe ke hana i kekahi hue. Ma nā kukui LED COB, akā naʻe, ʻelua mau mea pili a hoʻokahi kaapuni. ʻAʻole hiki ke hoʻohana iā lākou e hana i nā kukui hoʻololi kala a i ʻole nā ​​ʻōpala. Pono nā hoʻololi hoʻololi ʻana he nui no ka loaʻa ʻana o ka hopena hoʻololi kala. ʻO ka hopena, hana maikaʻi nā kukui COB LED i nā noi e koi ana i hoʻokahi hue akā ʻaʻole nā ​​kala he nui.

Loaʻa i nā ʻāpana SMD kahi ʻōlinolino kaulana o 50 a 100 lumens i kēlā me kēia watt. Ua ʻike maikaʻi ʻia ka maikaʻi wela nui a me nā lumens per watt ratio o COB. Hiki i nā pahu COB ke hoʻokuʻu i nā lumens me ka liʻiliʻi o ka uila inā loaʻa iā lākou he 80 mau lumens ma ka watt. Hiki ke loaʻa iā ia i loko o nā ʻano puʻupuʻu a me nā mea hana like ʻole, e like me ka uila ma kāu kelepona a i ʻole nā ​​pahu kiʻi kiko-a-pana.

Pono kahi kumu ikehu waho liʻiliʻi no nā chip SMD LED, aʻo kahi kumu ikehu waho nui e koi ʻia no nā chip LED COB.
