ʻO ka hoʻomohala ʻana o LED

ʻO ka hoʻomohala ʻana o ka LED mai ka ʻike ʻana i ke keʻena hana a hiki i kahi revolution kukui honua.
-Kuhi kukui home:ʻO nā kukui LED, nā kukui kaupaku, nā kukui pākaukau
-Kuhi kukui:nā kukui iho, nā kukui, nā kukui panel
-Ke kukui ʻoihana:kukui mining, high shed lights
-Ke kukui o waho:nā kukui alanui, nā kukui ʻāina, nā kukui loko
- Ke kukui kaʻa:Nā kukui LED, nā kukui lā, nā kukui hope
-Hōʻike LED:pale hoʻolaha, Mini LED TV
-Kuhi kukui:UV curing lamp, kukui ulu mea kanu

I kēia mau lā, hiki iā mākou ke ʻike i ka LED ma nā wahi āpau o ko mākou ola, ʻo ia ka hopena o kahi kokoke i hoʻokahi haneli o ka hoʻoikaika ʻana, hiki iā mākou ke ʻike maʻalahi i ka hoʻomohala ʻana o ka LED ma ke ʻano he 4 mau pae:
1. Nā ʻimi ʻimi mua (early 20th century -1960s)
-Ka ʻike ʻana o ka electroluminescence (1907)
Ua ʻike mua ka ʻenekini Pelekane ʻo Henry Joseph Round i ka electroluminescence ma nā crystals silicon carbide (SiC), akā ʻaʻole ia i aʻo hohonu.
I ka makahiki 1927, ua aʻo hou ka ʻepekema Soviet ʻo Oleg Losev i kahi pepa, i manaʻo ʻia ʻo ia ka "makuakāne o ke kumumanaʻo LED", akā ua hoʻopau ʻia ka noiʻi ma muli o ke Kaua Honua II.

-Ua hānau ʻia ka LED hana mua (1962)
Nick Holonyak Jr., General Electric (GE) Engineer I invented the first visible light LED (red light, GaAsP material). This marks the LED from the laboratory to commercialization, originally used for instrument indicators.

2. Ka holomua o ke kala kala (1970s-1990s)
-Ua hoʻokomo ʻia nā alakaʻi ʻōmaʻomaʻo a melemele (1970s)
1972: Ua haku ʻo M. George Craford (haumāna o Holonyak) i ke kukui melemele (10 mau manawa ʻoi aku ka mālamalama).
1980s: Aluminum, gallium and arsenic (AlGaAs) mea i hoʻomaikaʻi nui i ka pono o nā led ʻulaʻula, i hoʻohana ʻia i nā kukui uila a me nā lako uila.

-Blue LED kipi (1990s)
1993: Kepani 'epekema Shuji Nakamura (Shuji Nakamura) ma Nichia kemika (Nichia) breakthrough gallium nitride (GaN) ma muli polū LED, lanakila i ka 2014 Nobel Prize ma ka physics. This marks Blue LED + phosphor = white LED, e kau ana i ke kahua o ke kukui LED hou.

3. Ke kaulana o nā LED keʻokeʻo a me nā kukui (2000s-2010s)
-Ke kūʻai pāʻoihana LED keʻokeʻo (2000s)
Ua hoʻokumu ʻo Nichia Chemical, Cree, Osram a me nā hui ʻē aʻe i nā alakaʻi keʻokeʻo kiʻekiʻe e hoʻololi mālie i nā kukui incandescent a fluorescent.
2006: Ua hoʻokuʻu ka hui ʻAmelika Cree i ka LED 100lm/W mua, ʻoi aku ka maikaʻi o ke kukui fluorescent.
(Ma ka 2006 Heguang Lighting e hoʻomaka e hana i ke kukui o lalo o ke kai)

-LED i ke kukui maʻamau (2010s)
2010s: Ua emi nui ke kumu kūʻai o LED, a ua hoʻokō nā ʻāina a puni ka honua i ka "pā keʻokeʻo" (e like me ka EU hoʻopau ʻana i nā kukui incandescent ma 2012).
2014: Hāʻawi ʻia ka Nobel Prize in Physics iā Isamu Akasaki, Hiroshi Amano a me Shuji Nakamura no nā haʻawina i nā alakaʻi uliuli.

4. ʻenehana LED hou (2020s a hiki i kēia manawa)
-Ke kukui liʻiliʻi a me ke kukui uila
Mini LED: Hoʻohana ʻia no nā TVS kiʻekiʻe (e like me Apple Pro Display XDR), nā pale esports, ʻoi aku ka maikaʻi o ka backlight.
ʻO Micro LED: nā pixels luminous ponoʻī, manaʻo ʻia e pani i ka OLED (Samsung, SONY i hoʻokumu i nā huahana prototype).

- Ke kukui akamai a me ka Li-Fi
LED akamai: hiki ke hoʻololi ʻia ke kala kala, ka hoʻokele pūnaewele (e like me Philips Hue).
Li-Fi: ʻO ka hoʻohana ʻana i ke kukui LED e hoʻouna i ka ʻikepili, ʻoi aku ka wikiwiki ma mua o Wi-Fi (ua hiki i ka laboratories 224Gbps).

- UV LED a me nā noi kūikawā
Uv-c LED: Hoʻohana ʻia no ka sterilization (e like me nā lako disinfection UV i ka wā o ke ahulau).
ʻO LED ulu ulu: Hoʻoponopono kikoʻī e hoʻomaikaʻi i ka pono mahiʻai.

Mai ka "kukui hōʻailona" a i ka "kukui nui": hoʻonui ʻia ka maikaʻi e 1,000 mau manawa a hoʻemi ʻia ke kumukūʻai e 99%, hoʻemi ʻia ka hoʻolaha LED honua i nā haneli miliona o ka CO₂ emissions i kēlā me kēia makahiki, ke hoʻololi nei ʻo LED i ka honua! i ka wā e hiki mai ana, hiki i ka LED ke hoʻololi i ka hōʻike, kamaʻilio, ka lāʻau lapaʻau a me nā ʻoihana ʻē aʻe he nui! E kali mākou a ʻike!
