ʻO LED (Light Emitting Diodes) ka mea hou a hoihoi loa i ka ʻenehana i ka ʻoihana kukui, i ʻike hou ʻia a kaulana i kā mākou mākeke ma muli o kāna mau mea maikaʻi - ka mālamalama kiʻekiʻe, ke ola lōʻihi a me ka hoʻomanawanui - Nā kumu kukui e pili ana i ka ʻenehana semiconductor P a ʻo N a hiki i ka 20 manawa ʻoi aku ka lōʻihi o ke ola lawelawe ma mua o nā kukui fluorescent a i ʻole nā ​​​​kukui kukui.ʻAe kēia iā mākou e papa inoa i nā pono he nui okukui LED.

ʻO nā diodes māmā he mea nui i hoʻohana ʻia i ka uila no nā makahiki he nui, akā i kēia manawa ua loaʻa iā lākou kona kaulana ma muli o nā LED mana kiʻekiʻe, e hāʻawi ana i ka mālamalama ikaika e hoʻohana ʻia i pani no nā kukui fluorescent mercury. nā ʻōpuʻu.

I kēia manawa, aia nā kumu LED a me nā modules i loaʻa ma ka mākeke, i ikaika loa e hoʻohana ʻia e like me ke kukui uila e like me ke kukui alanui a i ʻole nā ​​​​kukui paka, a me nā kukui hoʻolālā o nā hale keʻena, nā kahua pāʻani a me nā alahaka.Hoʻohana pū lākou i kumu kumu o ka mālamalama i nā mea kanu hana, nā hale kūʻai a me nā keʻena keʻena.

I nā ʻōnaehana LED e pani ana i nā kukui maʻamau, ʻo nā kukui maʻamau i hoʻohana ʻia ʻo LED SMD a me COB i kapa ʻia ʻo Chip LED me nā huahana mai 0.5W a 5W no nā kukui hale a mai 10W - 50W no ka hoʻohana ʻana i ka ʻoihana.No laila, ua LED kukui kona pono?ʻAe, akā aia nō kona mau palena.He aha lākou?

Nā pōmaikaʻi o ke kukui LED

Ke ola lōʻihi- ʻo ia kekahi o nā pōmaikaʻi nui o nā kukui LED.ʻO nā LED i hoʻohana ʻia i kēia ʻano kukui he hana kiʻekiʻe a hiki ke holo a hiki i 11 mau makahiki ke hoʻohālikelike ʻia me nā kukui mālama ola me ke ola lawelawe ma lalo o hoʻokahi makahiki.Eia kekahi laʻana,ʻo nā LED e hana ana i nā hola 8 i kēlā me kēia lā e mau ana no kahi o 20 mau makahiki o ke ola lawelawe, a ma hope wale nō o kēia manawa, e koiʻia mākou e pani i ke kumu kukui no ka mea hou.Eia kekahi, ʻaʻohe hopena maikaʻi ʻole o ka hoʻololi pinepine ʻana i ke ola lawelawe, ʻoiai he hopena ia i ka hihia o kahi ʻano kukui kahiko.

Efficiency - ʻO nā LED i kēia manawa ke kumu ikaika loa o ka hoʻohana ʻana i ka ikehu (ka uila) ma mua o nā kukui incandescent, fluorescent, meta halide a i ʻole nā ​​kukui mercury, i loko o ka pono kukui o 80-90% no nā kukui kuʻuna.ʻO kēia ke ʻano o ka 80% o ka ikehu i hāʻawi ʻia i ka mea hana i hoʻololi ʻia i ka māmā, aʻo 20% ka nalowale a hoʻololi ʻia i ka wela.Aia ka 5-10% o ka maikaʻi o ke kukui incandescent - ʻo ia wale nō ka nui o ka ikehu i hoʻolako ʻia i hoʻololi ʻia i māmā.

Ke kū'ē i ka hopena a me ka mahana - ma keʻano likeʻole me nā kukui maʻamau,ʻo ka maikaʻi o ka kukui LEDʻaʻole ia i loko o nā filaments a iʻole nā ​​mea aniani, kahi i maʻalahi i ka puhi a me ka'ōpū.ʻO ka mea maʻamau, i ke kūkulu ʻana i nā kukui LED kiʻekiʻe, hoʻohana ʻia nā plastics kiʻekiʻe a me nā ʻāpana alumini, ʻo ia ka mea e ʻoi aku ka lōʻihi o nā LED a kū i nā haʻahaʻa haʻahaʻa a me nā haʻalulu.

Hoʻololi wela - ʻO nā LED, i hoʻohālikelike ʻia me nā kukui kuʻuna, e hoʻoulu i ka wela liʻiliʻi ma muli o kā lākou hana kiʻekiʻe.ʻO kēia hana ikehu ka hapa nui o ka hana a hoʻololi i ka māmā (90%), ka mea e hiki ai ke hoʻopili pololei i ke kanaka me ke kumu o ke kukui LED me ka ʻole o ka ʻike ʻana i ke ahi ma hope o ka manawa lōʻihi o kāna hana a me ka hoʻohui ʻia i kaupalena ʻia i ka ʻike ʻana i ke ahi. hiki ke hana i loko o nā lumi i loko
hoʻohana ʻia nā kukui o ke ʻano kahiko, e wela ana i nā haneli he nui.No kēia kumu, ʻoi aku ka maikaʻi o ka hoʻomālamalama ʻana o LED no nā huahana a i ʻole nā ​​​​mea hana i ʻike nui ʻia i ka mahana.

Ecology - ʻo ka maikaʻi o ka kukui LED ʻo ia hoʻi ka ʻike ʻole o nā LED i nā mea ʻona e like me ka mercury a me nā metala ʻē aʻe e pōʻino ai ke kaiapuni, ʻokoʻa i nā kukui mālama ʻana i ka ikehu a he 100% recyclable, he aha ka mea e kōkua ai e hōʻemi i ka carbon dioxide. hoʻokuʻu.Loaʻa iā lākou nā pūhui kemika e pili ana i ke kala o kona māmā (phosphor), ʻaʻole ia e pōʻino i ke kaiapuni.

Kala - I ka ʻenehana LED, hiki iā mākou ke loaʻa i kēlā me kēia kala kukui kukui.He keʻokeʻo, ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli nā waihoʻoluʻu kumu, akā me ka ʻenehana o kēia mau lā, holomua ka holomua a hiki iā mākou ke loaʻa kekahi kala.He ʻekolu ʻāpana kēlā me kēia ʻōnaehana LED RGB, hāʻawi kēlā me kēia i kahi kala ʻokoʻa mai ka waihoʻoluʻu palette RGB - ʻulaʻula, ʻōmaʻomaʻo, uliuli.

Nā pōʻino

Kumukūʻai - ʻoi aku ka maikaʻi o nā kukui LED ma mua o nā kumu kukui maʻamau.Eia naʻe, he mea nui e hoʻomanaʻo e ʻoi aku ka lōʻihi o ke ola ʻana (ma mua o 10 mau makahiki) ma mua o nā ʻōpuʻu kukui maʻamau a ma ka manawa like e hoʻopau ai i nā manawa he nui ka liʻiliʻi ma mua o ke ʻano kukui kahiko.I ka hana ʻana o kahi kumu kukui LED o kahi ʻano maikaʻi, e koi ʻia mākou e kūʻai i min.5-10 mau puʻupuʻu o ke ʻano kahiko, ʻaʻole ia e hopena i ka mālama ʻana i kā mākou ʻeke.

ʻIke wela - ʻO ka maikaʻi o nā kukui diodes e hilinaʻi nui ʻia i ka mahana hana ambient.Ma nā wela kiʻekiʻe, aia nā hoʻololi i nā ʻāpana o kēia manawa e hele ana i nā mea semiconductor, hiki ke alakaʻi i ka puhi ʻana i waho o ka module LED.Pili kēia pilikia i nā wahi a me nā ʻili i ʻike ʻia i ka piʻi wikiwiki ʻana o ka mahana a i ʻole ka wela kiʻekiʻe loa (nā wili kila).
