He aha ke kumukānāwai kukui o nā kukui LED?

He aha ke kumukānāwai kukui o nā kukui LED? ʻO ke kukui LED he chip electroluminescent semiconductor material, i hoʻōla ʻia ma ka bracket me ke kala kala a i ʻole ke keʻokeʻo keʻokeʻo, a laila pili i ka chip a me ka papa kaapuni me nā uea kālā a i ʻole gula, a hoʻopaʻa ʻia me ka resin epoxy a puni ia e pale ai i ka uea i loko. ʻO ka hana, ua hoʻokomo ʻia ka pūpū i hope, no laila maikaʻi ke kūpaʻa haʻalulu o ke kukui LED. 1. ʻO ka pahu kukui ʻO kekahi o nā hale hoʻomāmā nui o nā kukui LED (Light Emitting Diode) ʻo ia ka pahu kukui e like me ka nui o nā pi mung i loko o ke kukui. ʻOiai he liʻiliʻi kona nui, ʻaʻole liʻiliʻi kāna hana.

Ma hope o ka hoʻonui ʻana i ke ʻano o ka pahu kukui LED, e ʻike mākou i kahi wafer e like me ka hua sesame. He paʻakikī loa ke ʻano o ka chip, a ua māhele ʻia i nā ʻāpana he nui: ʻo ka papa Z luna i kapa ʻia ʻo ka papa semiconductor P-type, ʻo ka papa waena ka papa kukui-emitting, a ʻo ka papa lalo Z i kapa ʻia ʻo ka papa semiconductor ʻano N. No laila, pehea ke kukui LED? 2. ʻO ke kumu o ka hoʻokuʻuʻana i ka māmā Mai kahiʻike kino: i ka wā e hele ai ke au i ka wafer, nā electrons i ka N-type semiconductor a me nā puka o ka P-type semiconductor e hoʻokuʻi ikaika a hui hou i ka papa kukui e hana i nā photons, e hoʻopuka i ka ikehu ma keʻano o nā photons (ʻo ia hoʻi, ke kukui āu eʻike ai).

Ua kapa ʻia ʻo LED LED i ka light emitting diode, liʻiliʻi loa kona leo a palupalu loa, ʻaʻole kūpono ke hoʻohana pololei. No laila ua hoʻohui ka mea hoʻolālā i kahi pūpū pale iā ia a hoʻopaʻa ʻia i loko, no laila e hana i kahi kukui kukui LED maʻalahi. Ma hope o ka hoʻohui ʻana i nā pahu kukui LED he nui, hiki ke hana ʻia nā kukui LED like ʻole.

3. Nā kukui LED o nā kala like ʻole Nā semiconductors o nā mea like ʻole e hana i nā kala like ʻole o ke kukui, e like me ke kukui ʻulaʻula, ke kukui ʻōmaʻomaʻo, ke kukui uliuli a pēlā aku. Eia naʻe, ʻaʻohe mea semiconductor hiki ke hoʻokuʻu i ke kukui keʻokeʻo i kēia manawa. Akā pehea ka hana ʻana o nā kukui kukui LED keʻokeʻo a mākou e hoʻohana pinepine ai? 4. Hoʻokumu i nā kukui LED keʻokeʻo ma aneʻi pono mākou e haʻi aku i kahi Nobel laureate - Kauka Shuji Nakamura.

Ua hana ʻo ia i ka LED uliuli, kahi i hoʻokumu i ke kumu no ka LED keʻokeʻo. Ma muli o kēia haʻawina koʻikoʻi, ua hāʻawi ʻia ʻo ia i ka Nobel Prize in Physics i ka makahiki 2014. No ke ʻano o ka hoʻololi ʻana o nā LED polū i nā LED keʻokeʻo, ʻo ke kumu nui loa aia kahi papa o ka phosphor i loko o ka chip.

ʻAʻole i loli nui ke kumu kumu hoʻoheheʻe kukui: Ma waena o ʻelua papa semiconductor, hui pū nā electrons a me nā lua e hana i nā photons polū i ka papa kukui. ʻO kahi ʻāpana o ke kukui polū i hana ʻia e hele i loko o ka uhi fluorescent a hoʻopuka pololei ʻia; ʻo ke koena e paʻi i ka uhi fluorescent a hui pū me ia e hana i nā kiʻi melemele. Hana ʻia ke kukui keʻokeʻo ma ka hui ʻana (ka hui ʻana) i nā kiʻi polū me nā kiʻi melemele.

I kēia manawa, maʻamau ka laulā noi o nā kukui LED. ʻO ka lawe ʻana i ka Xinshengkai Optoelectronics ma ke ʻano he laʻana, ua hoʻohana nui ʻia nā ʻāpana kukui LED i hana ʻia i loko o waho a me waho, ka hoʻonohonoho ʻana o ke alanui, nā mea kūʻai aku, nā kīhāpai, nā kaʻa, nā loko, nā hōʻailona hoʻolaha, nā hōkele, nā hale kūʻai kūʻai, KTV, nā wahi leʻaleʻa, a me nā mea ʻē aʻe.
