He aha nā kukui Led e kū ai?

ʻO nā kukui LED, ʻo ia hoʻi ka Light Emitting Diodes, ua lilo i mea kaulana i nā makahiki i hala ma muli o ko lākou ikaika ikaika, lōʻihi ke ola, a me ka versatility. Inā ʻoe i kamaʻāina i nā kukui LED a i ʻole e hoʻomaka ana e aʻo e pili ana iā lākou, he mea nui e hoʻomaopopo i ke ʻano o nā kukui LED a pehea e hiki ai iā lākou ke pōmaikaʻi iā ʻoe. Ma kēia ʻatikala, e ʻimi mākou i nā ʻano like ʻole o nā kukui LED, me kā lākou mōʻaukala, ʻenehana, hoʻohana, a me nā pono. Ma ka hopena o kēia ʻatikala, e ʻike ʻoe i nā kukui LED a me ko lākou koʻikoʻi i kēia ao.

Nā hōʻailona mōʻaukala o nā kukui LED

Hoʻomaka ka mōʻaukala o nā kukui LED i ke kenekulia 20 i ka wā i ʻike ai nā ʻepekema i ke ʻano o ka electroluminescence i kekahi mau mea semiconductor. Eia naʻe, ʻaʻole hiki i ka makahiki 1960 ke kūkulu ʻia nā kukui LED pono. Ua hoʻokumu ʻia ka LED hana mua e Nick Holonyak Jr. i ka makahiki 1962 ʻoiai e hana ana no General Electric. Ua hoʻopuka kēia LED mua i kahi kukui ʻulaʻula haʻahaʻa, akā ua kau i ke kumu no ka hoʻomohala ʻana i nā kukui LED kiʻekiʻe i nā makahiki e hiki mai ana.

I nā makahiki he nui e hiki mai ana, ua holomua nā mea noiʻi a me nā ʻenekinia i ka ʻenehana LED, e alakaʻi ana i ka hoʻomohala ʻana i nā kukui LED i nā kala like ʻole a me ka ikaika. I nā makahiki 1990, ua hana maikaʻi ʻia nā LED polū, i hiki ai ke hana i nā kukui LED keʻokeʻo. I kēia lā, loaʻa nā kukui LED i nā ʻano kala like ʻole a hoʻohana ʻia i nā noi he nui, mai nā kukui hale a i nā hōʻike uila.

Nā ʻenehana hōʻailona ma hope o nā kukui LED

Hoʻokumu ʻia ka ʻenehana ma hope o nā kukui LED ma ke kumu o ka electroluminescence, ʻo ia ke kaʻina hana o ka hoʻokuʻu ʻana i ke kukui ma muli o ke kahe uila e hele ana i kahi mea semiconductor. Aia nā kukui LED i kahi diode semiconductor e hoʻopuka ana i ka mālamalama i ka wā e hele ai kahi au uila. ʻO nā mea semiconductor maʻamau i hoʻohana ʻia i nā kukui LED he gallium arsenide, gallium phosphide, a me gallium nitride.

ʻIke ʻia nā kukui LED no ko lākou ikehu ʻana, ʻoiai lākou e hoʻololi i ka pākēneka kiʻekiʻe o ka ikehu uila i māmā ke hoʻohālikelike ʻia me nā kukui incandescent a i ʻole nā ​​kukui fluorescent. Loaʻa kēia ma o ka hoʻohana ʻana i kahi "bandgap" i ka mea semiconductor, e hiki ai ke hoʻololi maikaʻi i ka ikehu i ka mālamalama. Eia kekahi, ʻoi aku ka lōʻihi o ke ola o nā kukui LED ma mua o nā kukui kuʻuna, me kekahi mau LED a hiki i 50,000 mau hola a ʻoi aku paha.

Hoʻohana ʻia nā hōʻailona o nā kukui LED

Hoʻohana ʻia nā kukui LED i nā ʻano hana like ʻole, mai ka hoʻomālamalama ʻana o ka hale i nā kumu kūʻai a me nā ʻoihana. Ma nā wahi noho, hoʻohana mau ʻia nā kukui LED no ka kukui maʻamau, nā kukui hana, a me nā kukui hoʻonaninani. ʻO ko lākou ikaika ikaika a me ka lōʻihi o ke ola e lilo lākou i koho kūpono no ka hōʻemi ʻana i ka hoʻohana ʻana i ka ikehu a me nā kumukūʻai mālama. Hoʻohana ʻia nā kukui LED i nā hōʻike uila, e like me nā uaki kikohoʻe, nā kukui uila, a me nā hōʻailona waho, ma muli o ko lākou ʻālohilohi a me ka ʻike.

Ma nā ʻoihana pāʻoihana a me nā ʻoihana, hoʻohana ʻia nā kukui LED no nā kumu like ʻole, me nā kukui hale kūʻai, nā kukui alanui, a me nā kukui kūkulu hale. Hoʻohana nui ʻia nā kukui LED i nā noi kaʻa a me ka lawe ʻana, e like me nā kukui poʻo, nā kukui uila, a me nā kukui o loko. ʻO ka versatility a me ka lōʻihi o nā kukui LED e kūpono iā lākou no ka nui o nā noi i loko a me waho.

Nā hōʻailona pono o nā kukui LED

Nui nā pono o ka hoʻohana ʻana i nā kukui LED i hoʻohālikelike ʻia me nā ʻenehana kukui kuʻuna. ʻO kekahi o nā pōmaikaʻi nui, ʻo ia ka ikaika o ka ikehu, no ka mea, ʻoi aku ka liʻiliʻi o ka mana o nā kukui LED a hoʻonui i ka māmā, e hoʻemi ana i nā bila ikehu a hoʻemi i ka hopena o ke kaiapuni. ʻOi aku ka lōʻihi o ke ola ʻana o nā kukui LED, ʻo ia hoʻi ka emi ʻana o ka hoʻololi pinepine ʻana a me ka haʻahaʻa o ke kumukūʻai mālama.

ʻO kekahi pōmaikaʻi o nā kukui LED ko lākou versatility ma ke ʻano o ke kala a me ka ikaika. Hiki i nā kukui LED ke hana i nā ʻano kala like ʻole, e kūpono iā lākou no nā hopena kukui a me nā noi. Hoʻohui ʻia, ʻaʻa koke nā kukui LED a ʻaʻole koi i ka manawa pumehana, ʻaʻole like me kekahi mau kukui kuʻuna. He mea kūpono kēia no nā noi kahi e pono ai ka hoʻopuka māmā koke ʻana, e like me ke kukui pilikia a me nā kukui hoʻoneʻe.

Nā hōʻailona i ka wā e hiki mai ana o nā kukui LED

Ke nānā aku nei ka wā e hiki mai ana o nā kukui LED, me ka hoʻomau ʻana o ka noiʻi a me ka hoʻomohala ʻana i ka hoʻomaikaʻi hou ʻana i ko lākou pono, ke ola, a me ka versatility. Ke hana nei nā mea noiʻi i ka hoʻomohala ʻana i nā mea semiconductor ʻoi aku ka maikaʻi a me nā kaʻina hana e hōʻemi i ke kumu kūʻai o nā kukui LED a hiki i nā mea kūʻai aku.

Ke ulu nei ka hoihoi i ka hoʻokō ʻana i nā ʻōnaehana kukui akamai e hoʻohana ana i ka ʻenehana LED e hāʻawi i nā hoʻonā kukui kūpono a me ka ikehu. Hiki ke hoʻokele mamao ʻia kēia mau ʻōnaehana kukui akamai me ka hoʻohana ʻana i nā smartphones a i ʻole nā ​​​​mea hana ʻē aʻe, e ʻae i nā mea hoʻohana e hoʻoponopono i ka ʻōlinolino, kala, a me ka hoʻonohonoho ʻana e like me kā lākou makemake. Hoʻohui ʻia, ʻo ka hoʻohui ʻana o nā kukui LED me nā sensor a me ka ʻenehana automation e manaʻo ʻia e hoʻonui hou i ka mālama ʻana i ka ikehu a me ka maʻalahi o nā ʻōnaehana kukui LED.

I ka hopena, ua hele lōʻihi nā kukui LED mai ko lākou hoʻomaka ʻana i nā makahiki 1960, a ua lilo lākou i ʻāpana nui o nā kukui a me nā ʻenehana hōʻike. ʻO ka mōʻaukala, ka ʻenehana, ka hoʻohana ʻana, a me nā pono o nā kukui LED e hāʻawi i ko lākou koʻikoʻi i kēia ao. Ke hoʻomau nei ka noiʻi a me ka hoʻomohala ʻana i ka hoʻomaikaʻi ʻana i ka ʻenehana LED, hiki iā mākou ke manaʻo e ʻike i nā noi hou aʻe a me nā pono o nā kukui LED i ka wā e hiki mai ana. Inā ma nā wahi noho, kālepa, a ʻoihana paha, kū nā kukui LED no ka pono o ka ikehu, lōʻihi, a me ka versatility, e hoʻolilo iā lākou i koho hoʻomau a kūpono no nā hoʻonā kukui.
