ʻO ka hana ʻana o nā LED (light emitting diodes) he kaʻina hana nui e pili ana i nā haʻawina mai nā ʻepekema he nui. Eia kekahi mau moʻolelo koʻikoʻi i ka hana ʻana o nā LED:
ʻO ka manaʻo mua a me nā hoʻokolohua:
1907:Ua ʻike mua ka mea ʻepekema Pelekane ʻo HJ Round e hoʻopuka ka semiconductor material silicon carbide (SiC) i ka mālamalama ke hoʻohana ʻia ka uila. ʻO kēia ka hanana electroluminescence mua i hoʻopaʻa ʻia o nā mea semiconductor.
1920s:Ua aʻo hou ka ʻepekema Lūkini ʻo Oleg Losev i kēia hanana a paʻi i kahi pepa e pili ana i nā loina o nā LED i ka makahiki 1927, akā ʻaʻole ia i huki i ka manaʻo ākea i kēlā manawa.
Hoʻomohala ʻana i nā LED kūpono:
1962:Ua haku ʻo Nick Holonyak Jr., he ʻenekinia e hana ana ma General Electric (GE) i kēlā manawa, i ke kukui ʻike maka mua (LED ʻulaʻula). Ua ʻike ʻia ʻo Holonyak ʻo "Father of LEDs".
1972:Ua haku ʻo M. George Craford, he haumāna o Holonyak, i ka LED melemele mua loa a ua hoʻomaikaʻi nui i ka ʻōlinolino o nā LED ʻulaʻula a me ka ʻalani. Ua hana ʻo ia i nā hoʻomaikaʻi e pili ana i ka gallium nitride phosphorus (GaAsP) mea e hoʻonui ai i ka ʻōlinolino o nā LED he ʻumi.
Nā makahiki 1970 a me nā makahiki 1980: Ua alakaʻi ʻia ka ʻenehana holomua i ka hana ʻana i nā LED i nā kala ʻē aʻe, me ka ʻōmaʻomaʻo, melemele, a me ka ʻalani.
ʻO ka pōʻeleʻele kukui LED:
1990s:Ua hana nā kānaka ʻepekema ma Hitachi a me Nichia, ʻo ia hoʻi ʻo Shuji Nakamura, i nā LED polū kiʻekiʻe. He holomua nui kēia me ka hoʻohana ʻana i nā mea gallium nitride (GaN). ʻO ka hana ʻana o nā LED polū i hana i nā hōʻike piha kala a me nā LED keʻokeʻo.
2014:Ua loaʻa iā Shuji Nakamura, Isamu Akasaki, a me Hiroshi Amano ka makana no ka Nobel ma Physics no kā lākou hana ma nā LED polū.
Hoʻomohala ʻana i nā LED keʻokeʻo:
Hana ʻia nā LED keʻokeʻo e ka hui ʻana i nā LED polū me nā phosphors. ʻO ke kukui polū mai ka LED uliuli e hoʻohauʻoli i ka phosphor, a laila e hoʻokuʻu i ke kukui melemele, a ʻo ka hui pū ʻana o nā mea ʻelua e hoʻopuka i ke kukui keʻokeʻo.
ʻO nā holomua i ka ʻenehana LED ua hopena i ka nui o nā kala LED ʻaʻole wale i ka laulā ʻike ʻia, akā i nā pae ultraviolet a me infrared. I kēia lā, hoʻohana ʻia nā LED i nā ʻano noi like ʻole, me nā hōʻike, nā kukui, nā kukui kuhikuhi, a me nā kamaʻilio.
Hōʻike ka mea aʻe i ka hoʻohālikelike kumu a me ka hoʻohana ʻana o LED
● Hoʻokaʻawale ʻia e ka mana hoʻopuka: 0.4W, 1.28W, 1.4W, 3W, 4.2W, 5W, 8W, 10.5W, 12W, 15W, 18W, 20W, 23W, 25W, 30W, 4W, 10.5W, 12W, 10.5W , 200W, 300W, etc.

●Ka hoʻokaʻawale ʻana ma ke ʻano hiʻohiʻona: ʻelua ʻano: PCBA papa ʻole a me ka pūpū.
●Ka hoʻokaʻawale ʻana ma ke ʻano palekana: ʻelua ʻano: kaʻawale a me ka ʻole.
●Ka helu ʻana e ka mana: me ka hoʻoponopono ʻana i ka mana a me ka ʻole o ka mana.
●Ka hoʻokaʻawale ʻana ma o ka hana wai ʻole: ʻaʻohe wai a me ka wai ʻole.
●Ka hoʻokaʻawale ʻana ma ke ʻano hoʻohiwahiwa: ka hoʻoulu ʻana iā ia iho a me ka hoʻoulu ʻana o waho.
●Ka helu ʻana ma ka topology kaapuni: RCC, Flyback, Forward, Half-Bridge, Full-Bridge, Push-PLL, LLC, etc.
●Ka helu ʻana ma ke ʻano hoʻololi: AC-DC a me DC-DC.
●Ka hoʻokaʻawale ʻana ma o ka hana hoʻopuka: ka manawa mau, ka uila mau a me ka uila mau a me ka uila mau.
Ka hoʻohana ʻana i ka lako mana hoʻokele LED:
Hoʻohana ʻia no nā kukui kikoʻī, nā kukui keʻena, nā kukui pō, nā kukui pale maka, nā kukui kaupaku LED, nā kīʻaha kukui, nā kukui kanu, nā kukui o lalo o ka wai, nā mea holoi paia, nā kukui, nā kukui alanui, nā pahu kukui hōʻailona, nā kukui kaula, nā kukui iho, nā kukui ʻano kūikawā, nā hōkū. nā kukui, nā kukui pale, nā kukui ānuenue, nā kukui pā pale, nā kukui hikiwawe, nā kukui wehe, nā kukui kāʻei, nā kukui piranha, nā kukui uila, nā kukui pou kiʻekiʻe, nā kukui alahaka, nā kukui mining, nā kukui, nā kukui pilikia, nā kukui papaʻaina, nā kukui, nā kukui uila, nā kukui mālama ikehu, nā huelo kaʻa, nā kukui lawn, nā kukui kala, nā kukui aniani, nā kukui grille, nā kukui tunnel, etc.
ʻO mākou kahi mea hoʻolako mana LED ʻoihana ma Kina, hoʻokipa e nānākā mākou papa inoa huahana.
E ʻoluʻolu e kūkākūkā no nā hiʻohiʻona hou aʻe, kākoʻo i nā huahana maʻamau.
