He aha nā ʻokoʻa ma waena o nā ʻāpana kukui cob a me nā ʻāpana kukui LED maʻamau?
ʻO ka ʻokoʻa ma waena o nā ʻāpana kukui cob a me nā ʻāpana kukui alakaʻi
He aha nā kukui LED a me nā kukui COB
ʻO ke kukui LED, ʻo ka inoa piha he kukui-emitting diode kukui, he kumu kukui semiconductor. Aia ia me kahi hui PN. Ke hui hou nā electrons a me nā puka i ka hui PN, hiki mai ka hoʻokuʻu māmā. Loaʻa i nā kukui LED nā pōmaikaʻi o ka hana kiʻekiʻe, ke ola lōʻihi, ke kala kukui saturated, ka mālama ʻana i ka ikehu a me ka mālama ʻana i ke kaiapuni, a me nā mea ʻē aʻe, no laila ua hoʻohana nui ʻia lākou i ke kukui, hōʻike, hōʻailona a me nā māla ʻē aʻe.
ʻO ke kukui COB, kahi e kū nei no ka pahu kukui i hoʻopili ʻia, he ʻano kumu kukui hou. Hoʻopili ia i nā pahu kukui LED he nui ma ka substrate hoʻokahi e hana i kahi kumu kukui semiconductor e hoʻololi i nā pahu kukui LED kuʻuna, a laila e loaʻa ai ka ʻoi aku ka maikaʻi o ka māmā a me ka ʻōlinolino kiʻekiʻe. Loaʻa i nā kukui COB nā mea maikaʻi o ke kukui kiʻekiʻe, ke kala kukui ʻokoʻa, a me ka mālamalama kiʻekiʻe, no laila ua hoʻohana nui ʻia lākou i nā kukui kalepa, nā kukui o loko a me nā māla ʻē aʻe.
- Hoʻolālā kumu māmā
ʻO ke kukui COB (Chip on Board) kahi kukui e hoʻohui i nā pahu kukui LED ma kahi pani. Hoʻonohonoho ʻia nā ʻāpana LED he nui ma luna o ka substrate ma kahi ʻaoʻao e hana i kahi holoʻokoʻa, a ʻo ka wahi e hoʻomālamalama i ke kukui e hoʻomau a ʻaʻahu. Hoʻonohonoho ka ʻāʻī kukui LED (Light Emitting Diode) i nā pahu kukui LED hoʻokahi ʻaoʻao ma ka ʻaoʻao o ke kaula kukui. No laila, ʻoi aku ka paʻa a me ka hoʻohui ʻana o ke kumu kukui o nā ʻāpana kukui COB, ʻoiai ʻoi aku ka hoʻopuehu ʻana o ke kumu kukui o nā ʻāpana kukui LED.
- ʻōlinolino
No ka mea, ʻoi aku ka paʻakikī o ka hoʻolālā kumu kukui o nā ʻāpana kukui COB, i ka hana ʻana o nā pahu kukui LED he nui i ka manawa like, ʻoi aku ka nui o ka wahi hoʻomālamalama a ʻoi aku ke kiʻekiʻe o ka ʻōlinolino. E like me ka hoʻopuehu ʻana o ke kumu kukui o nā ʻāpana kukui LED a liʻiliʻi nā pahu LED pākahi, haʻahaʻa ko lākou kukui. No laila, ke koi ʻia nā hopena kukui ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi o ke koho ʻana i nā ʻāpana kukui COB.
- ʻO ka ikaika o ka ikehu
ʻOi aku ka maikaʻi o ka hopena kukui o nā ʻāpana kukui COB, ua like ke kukui, ʻoi aku ka ikaika o ka hopena noʻonoʻo, a ʻoi aku ka kiʻekiʻe o ka ikehu. Ma muli o ka paʻa o kona ʻano kumu māmā, hiki i nā ʻāpana kukui COB ke hoʻomalu maikaʻi i ka kuhikuhi hoʻolaha o ka mālamalama a hōʻemi i ka nalowale o ka ikehu i ka wā o ke kukui. Eia naʻe, ʻoi aku ka haʻahaʻa o ka ikehu o nā ʻāpana kukui LED ma muli o nā kumu kukui i hoʻopuehu ʻia i ka wā o ke kaʻina hana.
- Kumukuai
No ka mea e koi ana nā ʻāpana kukui COB i nā kaʻina hana kiʻekiʻe a ʻoi aku ka maikaʻi o nā hopena kukui a me ka ikaika o ka ikehu, kiʻekiʻe ko lākou kumukūʻai. He haʻahaʻa loa ke kumukūʻai o nā ʻāpana kukui LED ma muli o kā lākou hana maʻalahi. No laila, ke kaupalena ʻia ke kālā, ʻoi aku ka maikaʻi o ke koho ʻana i nā ʻāpana kukui LED.
ʻElima mau hiʻohiʻona o nā kukui COB a me nā kukui LED
Loaʻa nā pono like ʻole o nā kukui COB a me nā kukui LED i nā hiʻohiʻona noiʻi like ʻole. ʻO kēia ka nānā ʻana mai ʻelua ʻaoʻao: ke kukui kalepa a me ke kukui o loko.
kukui kalepa
Pono nā hiʻohiʻona kukui ʻoihana i nā koi kala kiʻekiʻe, no laila makemake ʻia e koho i nā kukui COB. Ma muli o ka hoʻopili ʻana o nā kukui COB i nā ʻāpana LED he nui ma ka substrate hoʻokahi, ʻoi aku ka like o ke kala māmā a hiki ke hōʻike i nā kala maoli. I ka manawa like, ʻoi aku ka kiʻekiʻe o ka māmā o nā kukui COB a hiki ke hoʻokō i nā hopena kukui maikaʻi.
Ke kukui o loko
Pono nā hiʻohiʻona kukui o loko i nā hola hana lōʻihi, no laila e ʻōlelo ʻia e koho i nā kukui LED. ʻOiai ʻoi aku ka haʻahaʻa o ka māmā o nā kukui LED ma mua o nā kukui COB, ke hoʻohālikelike ʻia me nā ʻōpuʻu kukui kahiko a me nā kukui fluorescent, ʻoi aku ka kiʻekiʻe o ka māmā o nā kukui LED. I ka manawa like, ʻoi aku ka lōʻihi o ke ola o nā kukui LED, hiki ke hoʻokō i nā pono o ke kukui o loko no ka manawa lōʻihi.
Nā manaʻo no ke koho ʻana i nā kukui COB a me nā kukui LED
Ma muli o ke ʻano o ka noi, ʻokoʻa ka koho ma waena o nā kukui COB a i ʻole nā kukui LED. Eia nā manaʻo no ke koho ʻana i nā hiʻohiʻona like ʻole:
- Nā hiʻohiʻona kukui kālepa: Manaʻo ʻia e koho i nā kukui COB, hiki ke hoʻokō i ka koi no nā koi kala kiʻekiʻe.
- Nā hiʻohiʻona kukui i loko: Manaʻo ʻia e koho i nā kukui LED, hiki ke hoʻokō i nā pono o ke kukui lōʻihi.
- Nā hiʻohiʻona ʻē aʻe: E koho i nā kukui COB a i ʻole nā kukui LED e like me nā pono maoli.
I ka hōʻuluʻulu ʻana, aia nā ʻokoʻa ʻokoʻa ma waena o nā ʻāpana kukui COB a me nā ʻāpana kukui LED e pili ana i ke ʻano o ke kumu kumu kukui, ʻālohilohi, ka ikehu a me ke kumukūʻai. Loaʻa i nā ʻāpana kukui COB nā mea maikaʻi o ka hoʻolālā kumu kukui paʻa, ʻālohilohi kiʻekiʻe a me ka ikaika o ka ikehu kiʻekiʻe, a kūpono i nā manawa e koi ai i nā hopena kukui kukui a me ka mālama ʻana i ka ikehu. Loaʻa i nā ʻāpana kukui LED ka maikaʻi o nā kumukūʻai haʻahaʻa, a hiki ke hoʻokō i kekahi mau koi kukui ma lalo o nā pono kukui kikoʻī. No laila, i ke koho ʻana i nā ʻāpana māmā, pono ʻoe e noʻonoʻo pono e pili ana i nā pono kikoʻī a me nā kālā e hana i ka koho kūpono loa.
Ua hoʻololi ka ʻenehana LED i ke ala e hoʻomālamalama ai i ko mākou mau hale a me nā ʻoihana. ʻAʻole wale ʻo ia e lawe mai i ka pono o ka ikehu i ka kukui, hoʻomaikaʻi nō hoʻi i ka maikaʻi o ka mālamalama, e hiki ke hoʻololi ʻia i nā ʻano hoʻonohonoho like ʻole. ʻO ke kukui LED no ka light-emitting diode, he mea semiconductor e hoʻopuka ana i ka mālamalama ke hele ka uila i loko. ʻOi aku ka maikaʻi o ka ʻenehana LED ma mua o nā kukui kukui a me nā kukui fluorescent. Akā pehea ka maikaʻi o nā LED?
ʻO kekahi o nā hōʻailona koʻikoʻi o ka maikaʻi o ke kukui ʻo ka hoʻohana ʻana i ka ikehu. ʻIke ʻia ka ʻenehana LED no ka haʻahaʻa haʻahaʻa o ka ikehu, e lilo ia i koho kaulana no nā kukui hale a me nā ʻoihana. ʻO ka ʻoiaʻiʻo, mālama nā ʻōpuʻu LED a hiki i ka 80% ʻoi aku ka ikehu ma mua o nā ʻōpuʻu incandescent kuʻuna a ma kahi o 20-30% ʻoi aku ma mua o nā ʻōpuʻu fluorescent. ʻAʻole hoʻohaʻahaʻa wale ka hoʻemi ʻana o ka ikehu i nā bila uila a ka poʻe kūʻai aku akā kōkua pū kekahi i ka hōʻemi nui ʻana i ka hoʻokuʻu kalapona, e hoʻolilo ana i ka ʻenehana LED i koho kukui ʻoluʻolu.
ʻO nā mea a pau, ʻoi aku ka maikaʻi o ka ʻenehana LED ma ke ʻano o ka hoʻohana ʻana i ka ikehu, ka lōʻihi, ka puka māmā a me ka controllability. ʻO kona hoʻohana ʻana i ka ikehu haʻahaʻa, ke ola lōʻihi, ka puka kukui kiʻekiʻe a me ka hana hikiwawe e lilo ia i koho kukui maikaʻi loa i hoʻohālikelike ʻia i nā kukui incandescent a me nā kukui fluorescent. Ke hoʻomau nei ka noi no ka hoʻōla ʻana i ka ikehu a me ka hoʻonā ʻana i nā kukui uila e ulu ana, manaʻo ʻia ka ʻenehana LED e pāʻani i kahi kuleana koʻikoʻi i ka hana ʻana i ka wā e hiki mai ana o ke kukui.
