Kukula kwa LED

Kukula kwa LED kukuchokera ku zomwe zapezedwa mu labotale kupita kukusintha kowunikira kwapadziko lonse.
-Kuwunikira kunyumba:Mababu a LED, zowunikira padenga, nyali zapa desiki
-Kuwunikira kwamalonda:zowunikira, zowunikira, zowunikira
-Kuwunikira kwa mafakitale:nyali za migodi, zowunikira kwambiri
-Kuyatsa panja:nyali za mumsewu, zounikira malo, zounikira m'madzi
-Kuyatsa magalimoto:Zowunikira za LED, zowunikira masana, zowunikira
- Mawonekedwe a LED:skrini yotsatsa, Mini LED TV
-Kuwunikira kwapadera:Nyali yochiritsa ya UV, nyali yakukula kwa mbewu

Masiku ano, titha kuwona LED kulikonse m'moyo wathu, izi ndi zotsatira za khama pafupifupi zaka zana, titha kungodziwa kukula kwa LED monga kuwomba masitepe 4:
1.Kufufuza koyambirira (koyambirira kwa zaka za m'ma 1960)
-Kupezeka kwa electroluminescence (1907)
Katswiri wa ku Britain Henry Joseph Round adayamba kuona electroluminescence pa makristasi a silicon carbide (SiC), koma sanaphunzire mozama.
Mu 1927, wasayansi waku Soviet Oleg Losev adaphunziranso ndikusindikiza pepala, lomwe limawonedwa kuti ndi "bambo wa chiphunzitso cha LED", koma kafukufukuyu adasokonekera chifukwa cha Nkhondo Yachiwiri Yadziko Lonse.

-Woyamba wothandiza wa LED adabadwa (1962)
Nick Holonyak Jr., General Electric (GE) Engineer Anapanga kuwala koyambirira kowoneka kwa LED (kuwala kofiira, zinthu za GaAsP) .izi zimasonyeza kuwala kwa LED kuchokera ku labotale kupita ku malonda, komwe kumagwiritsidwa ntchito posonyeza zizindikiro za zida.

2. Kujambula kwamtundu wa LED (1970s-1990s)
- Ma LED obiriwira ndi achikasu adayambitsidwa (1970s)
1972: M. George Craford (wophunzira wa Holonyak) adayambitsa LED yachikasu (nthawi 10 yowala).
Zaka za m'ma 1980: Aluminium, gallium ndi arsenic (AlGaAs) zida zinathandizira kwambiri kuyendetsa bwino kwa ma LED ofiira, omwe ankagwiritsidwa ntchito popanga magetsi ndi zipangizo zamagetsi.

-Blue LED Revolution (1990s)
1993: Wasayansi wa ku Japan Shuji Nakamura (Shuji Nakamura) mu Nichia chemical (Nichia) atulukira gallium nitride (GaN) yochokera ku blue LED, adapambana mphoto ya Nobel ya 2014 mu physics.

3. Kutchuka kwa LED yoyera ndi kuyatsa (2000s-2010s)
-Kugulitsa kwa LED koyera (2000s)
Nichia Chemical, Cree, Osram ndi makampani ena adayambitsa zowongolera zoyera zowoneka bwino kuti zisinthe pang'onopang'ono nyali za incandescent ndi fulorosenti.
2006: Kampani ya American Cree idatulutsa 100lm/W LED yoyamba, kupitilira mphamvu ya nyali ya fulorosenti.
(Mu 2006 Heguang Lighting idayamba kupanga kuwala kwa LED pansi pamadzi)

- Kuwunikira kwa LED (2010s)
2010s: Mtengo wa LED watsika kwambiri, ndipo maiko padziko lonse lapansi atsatira "kuletsa zoyera" (monga EU inachotsa nyali za incandescent mu 2012).
2014: Nobel Prize in Physics yoperekedwa kwa Isamu Akasaki, Hiroshi Amano ndi Shuji Nakamura chifukwa cha zopereka za blue lead.

4. Ukadaulo wamakono wa LED (2020s mpaka pano)
- Mini LED & Micro LED
Mini LED: Imagwiritsidwa ntchito pa TVS yapamwamba (monga Apple Pro Display XDR), zowonetsera esports, zowunikira zowunikira kwambiri.
Micro LED: ma pixel odziwunikira okha, akuyembekezeka kulowa m'malo mwa OLED (Samsung, SONY ayambitsa zinthu zofananira).

- Kuwunikira kwanzeru ndi Li-Fi
Smart LED: kutentha kwamtundu wosinthika, kuwongolera maukonde (monga Philips Hue).
Li-Fi: Kugwiritsa ntchito kuwala kwa LED kufalitsa deta, mofulumira kuposa Wi-Fi (laboratory yafika 224Gbps).

- UV LED ndi ntchito zapadera
Uv-c LED: Imagwiritsidwa ntchito potsekereza (monga zida zophera tizilombo za UV panthawi ya mliri).
Kukula kwa mbewu za LED: mawonekedwe osinthika kuti apititse patsogolo ntchito zaulimi.

Kuchokera ku "kuwala kwachizindikiro" kupita ku "kuunika kwapakati" : Kuchita bwino kumawonjezeka nthawi 1,000 ndipo mtengo wake umachepetsedwa ndi 99%, kutchuka kwa LED padziko lonse kumachepetsa matani mamiliyoni mazana a mpweya wa CO₂ chaka chilichonse, LED ikusintha dziko! M'tsogolomu, LED ikhoza kusintha mawonedwe, mauthenga, mankhwala ndi mafakitale ena ambiri! Tidikirira kuti tiwone!
