Pehea e hana ai nā kukui alanui LED?

Ua hele lōʻihi nā kukui alanui mai nā lā mua o nā kukui kinoea a me nā ʻōpuʻu kukui. I kēia lā, ʻo nā kukui alanui LED ke kūlana paʻa loa - a no ke kumu maikaʻi. ʻO lākou ka ikaika o ka ikehu, ka lōʻihi a me ke kumu kūʻai. ʻO ka ʻoiaʻiʻo, ua hoʻololi ka nui o nā kūlanakauhale a puni ka honua i nā kukui alanui LED e mālama i ka hoʻohana ʻana i ka ikehu a hoʻemi i ka hoʻokuʻu kalapona.

Akā, pehea e hana ai nā kukui alanui LED? E luʻu kākou i ka ʻepekema a me ka ʻenehana ma hope o kēia mau mea kupanaha o ka mālamalama.

Ke poʻomanaʻo: Mai Incandescent a LED

Ma mua o ke komo ʻana i ke ʻano o ka hana ʻana o nā kukui alanui LED, e nānā wikiwiki kākou i ka mōʻaukala o ke kukui alanui. E hoʻomaka ana i nā makahiki 1800, hoʻomālamalama nā kukui kinoea i nā alanui o ke kūlanakauhale. ʻAʻole hiki i ka hopena o ka makahiki 1800 i ʻike nui ʻia nā kukui alanui uila. Eia nō naʻe, ua hoʻohana nā ʻano mua o nā kukui alanui uila i nā ʻōpuʻu kukui, ʻaʻole ikaika loa a lōʻihi.

A laila, i ka makahiki 1960, ua hana ʻia ka diode māmā mua (LED). Eia naʻe, ʻaʻole hiki i ka makahiki 1990 ka hoʻomaka ʻana o nā kukui LED e komo i loko o ka ʻoihana kukui alanui. I kēia manawa, ʻo nā kukui alanui LED ka mea maʻamau i nā kūlanakauhale he nui a puni ka honua.

Poʻomanaʻo: Nā ʻāpana koʻikoʻi o nā kukui alanui LED

Ma mua o ka nānā ʻana i ka hana ʻana o nā kukui alanui LED, pono mākou e hoʻomaopopo i nā ʻāpana kumu o kēia mau kukui. Eia nā ʻāpana kumu ʻehā:

- Nā pahu kukui LED: ʻO kēia nā kumu kukui liʻiliʻi e hana i ke kukui maoli.

- Ke alakaʻi alakaʻi LED: Hoʻoponopono kēia ʻāpana i ka mana i hāʻawi ʻia i nā chips LED a kōkua i ka hōʻoia ʻana i ka hoʻopuka paʻa.

- Heat sink: ʻO nā kukui alanui LED e hana i ka wela, no laila pono ka wela e hoʻopau a mālama i nā kukui mai ka wela.

- Pūnaehana Optical: Aia kēia me ka reflector a me ka lens, e kōkua i ke kuhikuhi ʻana i ke kukui ma kahi e pono ai.

Ke poʻomanaʻo: ʻO ka ʻepekema ma hope o nā kukui alanui LED

No laila, pehea e hana ai nā kukui alanui LED? Hele mai nā mea a pau i ka ʻepekema o semiconductors. Hoʻohana ka ʻenehana LED i nā semiconductor e hoʻohuli i ka ikehu uila i māmā. Ke holo ka uila ma kahi semiconductor, hoʻopuka ia i ka ikehu ma ke ʻano o nā photons. ʻO ke kala o ke kukui e pili ana i ke ʻano o ka semiconductor i hoʻohana ʻia.

ʻOi aku ka ikaika o nā LED ma mua o nā ʻōpuʻu incandescent no ka mea, hoʻololi lākou i ka ʻenekini a pau a lākou e hoʻohana ai i māmā. ʻO nā ʻōpuʻu incandescent, ma ka ʻaoʻao ʻē aʻe, hoʻopuka i ka nui o ka wela, kahi e pau ai ka ikehu. ʻOi aku ka maikaʻi o ke kumukūʻai o nā kukui alanui LED ma mua o ko lākou mau mea mua.

Ke poʻomanaʻo: Nā pono o nā kukui alanui LED

Hāʻawi nā kukui alanui LED i nā mea maikaʻi ma mua o nā ʻano kukui alanui ʻē aʻe. Eia kekahi o na pomaikai nui:

- ʻOi aku ka ikaika o nā kukui alanui LED ma mua o nā ʻōpuʻu incandescent a me nā ʻōpuʻu fluorescent.

- Ka lōʻihi loa: Hiki i nā kukui alanui LED ke hoʻomau i nā hola 100,000, ʻoi aku ka lōʻihi ma mua o nā ʻano kukui ʻē aʻe.

- Ka mālama haʻahaʻa: No ka lōʻihi o ka lōʻihi o nā kukui alanui LED, pono lākou i ka mālama liʻiliʻi ma mua o nā ʻano kukui alanui ʻē aʻe.

- Hoʻokuʻu haʻahaʻa: ʻO nā kukui alanui LED e hoʻokuʻu i ka CO2 a me nā mea haumia ʻē aʻe ma mua o nā ʻano kukui alanui ʻē aʻe.

- Directable: Hiki ke kuhikuhi pololei ʻia nā kukui alanui LED ma mua o nā ʻano kukui ʻē aʻe, ʻo ia hoʻi hiki iā lākou ke hoʻomālamalama i nā wahi kikoʻī i ʻoi aku ka maikaʻi.

Ke poʻomanaʻo: Nā noi o nā kukui alanui LED

Hoʻohana ʻia nā kukui alanui LED ma nā ʻano hoʻonohonoho like ʻole, mai nā kūlanakauhale nui a i nā ala kuaʻāina. Eia kekahi o nā noi maʻamau o nā kukui alanui LED:

- Nā alanui kūlanakauhale: Nui nā kūlanakauhale nui a puni ka honua i hoʻololi i nā kukui alanui LED e hōʻemi i ka hoʻohana ʻana i ka ikehu a me nā kumukūʻai haʻahaʻa.

- Alanui: Hoʻohana ʻia nā kukui alanui LED ma ke alaloa a me nā ʻōnaehana interstate e hāʻawi i ka ʻike maikaʻi a hōʻemi i nā pōʻino.

- Nā wahi noho: Ua kaulana nā kukui alanui LED ma nā wahi noho no ka mea hiki ke kuhikuhi ʻia lākou e hoʻomālamalama i nā wahi kikoʻī me ka ʻole o ke kahe ʻana i nā waiwai pili.

- Nā wahi kaʻa: Ua hoʻomālamalama ʻia nā wahi kaʻa he nui me nā kukui alanui LED no ka mea ʻoi aku ka maikaʻi a me ka ikaika.

Subheading: I ka hopena

ʻO nā kukui alanui LED he mea hou i ke kahua o ke kukui. ʻO lākou ka ikaika o ka ikehu, ka lōʻihi a me ke kumu kūʻai, e hoʻolilo iā lākou i mea kūpono no nā ʻano like ʻole. Ma ka hoʻomaopopo ʻana i ka hana ʻana o nā kukui alanui LED a me nā pōmaikaʻi koʻikoʻi a lākou e hāʻawi ai, hiki iā ʻoe ke mahalo nui i ka hopena i loaʻa iā lākou ma nā kūlanakauhale a me nā kūlanakauhale a puni ka honua.
