Ke kaʻina hana o nā kukui kukui LED

Ke kaʻina hana oNā lei kukui LEDhe loulou kī i ka ʻoihana kukui LED. ʻO nā kukui kukui LED, i ʻike ʻia he diodes māmā, he mau mea koʻikoʻi i hoʻohana ʻia i nā ʻano noi like ʻole mai nā kukui hale a i nā ʻōnaehana kukui a me nā ʻoihana. I kēia mau makahiki i hala iho nei, ma muli o nā pono o ka mālama ʻana i ka ikehu, ke ola lōʻihi, a me ka pale ʻana i ke kaiapuni o nā kukui kukui LED, ua piʻi nui kā lākou koi, e alakaʻi ana i ka holomua a me ka hoʻomaikaʻi ʻana i ka ʻenehana hana.

ʻO ke kaʻina hana o nā kukui kukui LED e pili ana i nā pae he nui, mai ka hana ʻana i nā mea semiconductor a hiki i ka hui hope o nā ʻāpana LED. Hoʻomaka ke kaʻina hana me ke koho ʻana i nā mea maʻemaʻe kiʻekiʻe e like me ka gallium, arsenic, a me ka phosphorus. Hoʻohui ʻia kēia mau mea i nā ʻāpana kūpono e hana i nā kristal semiconductor i hoʻokumu i ke kumu o ka ʻenehana LED.

Ma hope o ka hoʻomākaukau ʻana o ka mea semiconductor, hele ia ma kahi kaʻina hoʻomaʻemaʻe ikaika e wehe i nā haumia a hoʻonui i kāna hana. ʻO kēia kaʻina hana hoʻomaʻemaʻe e hōʻoia i ka hāʻawi ʻana o nā kukui kukui LED i ka ʻōlinolino kiʻekiʻe, ke kūlike o ka waihoʻoluʻu, a me ka pono ke hoʻohana ʻia. Ma hope o ka hoʻomaʻemaʻe ʻana, ʻoki ʻia ka mea i loko o nā wafers liʻiliʻi me ka hoʻohana ʻana i kahi ʻoki kiʻekiʻe.

ʻO ka hana aʻe i ke kaʻina hana e pili ana i ka hana ʻana i nā pahu LED iā lākou iho. Hoʻomaʻamaʻa maikaʻi ʻia nā wafers me nā kemika kikoʻī a hana i kahi kaʻina i kapa ʻia epitaxy, kahi e waiho ʻia ai nā papa o nā mea semiconductor ma luna o ka ʻili o ka wafer. Hana ʻia kēia deposition ma kahi kaiapuni i hoʻohana ʻia e like me ka metal-organic chemical vapor deposition (MOCVD) a i ʻole molecular beam epitaxy (MBE).

Ma hope o ka pau ʻana o ke kaʻina hana epitaxial, pono ka wafer e hele i ke ʻano o ka photolithography a me nā ʻanuʻu etching e wehewehe i ke ʻano o ka LED. Hoʻopili kēia mau kaʻina hana i ka hoʻohana ʻana i nā ʻenehana photolithography kiʻekiʻe e hana i nā hiʻohiʻona paʻakikī ma ka ʻili o ka wafer e wehewehe ana i nā ʻāpana like ʻole o ka chip LED, e like me nā ʻano p-type a me n-type, nā papa hana, a me nā pad contact.

Ma hope o ka hana ʻia ʻana o nā chips LED, hele lākou i ke kaʻina ʻana a me ka hoʻāʻo ʻana e hōʻoia i ko lākou maikaʻi a me ka hana. Hoʻāʻo ʻia ka chip no nā hiʻohiʻona uila, ʻālohilohi, ka wela o ka waihoʻoluʻu, a me nā ʻāpana ʻē aʻe e hoʻokō i nā kūlana i koi ʻia. Hoʻokaʻawale ʻia nā ʻāpana kīnā ʻole i ka wā e hele ana nā pahu hana i ka pae aʻe.

I ka pae hope o ka hana ʻana, ua hoʻopili ʻia nā pahu kukui LED i nā pahu kukui LED hope loa. ʻO ke kaʻina hana hoʻopili e pili ana i ka kau ʻana i nā ʻāpana ma luna o kahi pahu alakaʻi, hoʻopili iā lākou i nā pilina uila, a hoʻopili iā lākou i loko o kahi mea resin pale. Mālama kēia puʻupuʻu i ka chip mai nā mea kūlohelohe a hoʻonui i kona lōʻihi.

Ma hope o ka hoʻopaʻa ʻana, hoʻopili ʻia nā pahu kukui LED i nā hoʻāʻo hana hou, lōʻihi, a me ka hilinaʻi. Hoʻohālikelike kēia mau hoʻokolohua i nā kūlana hana maoli e hōʻoia i ka hana paʻa ʻana o nā kukui kukui LED a hiki ke kū i nā ʻano like ʻole e like me ka piʻi ʻana o ka mahana, ka haʻahaʻa, a me ka haʻalulu.

Ma ke ʻano holoʻokoʻa, paʻakikī loa ke kaʻina hana o nā kukui kukui LED, e koi ana i nā mīkini holomua, ka mana pololei, a me ka nānā ʻana i ka maikaʻi. ʻO nā holomua i ka ʻenehana LED a me ka hoʻonui ʻana i nā kaʻina hana i kōkua nui i ka hana ʻana i nā hoʻonā kukui LED i ʻoi aku ka ikaika, paʻa, a hilinaʻi. Me ka noiʻi hoʻomau a me ka hoʻomohala ʻana i kēia kahua, manaʻo ʻia e hoʻomaikaʻi hou ʻia ke kaʻina hana, a ʻoi aku ka maikaʻi o nā kukui kukui LED i ka wā e hiki mai ana.

Inā makemake ʻoe i ke kaʻina hana o nā kukui kukui LED, e hoʻokipa e kelepona i ka mea hana kukui alanui LED TIANXIANG iheluhelu hou.
