Horumarinta LED

Horumarinta LED-ku waxay ka timid shaybaadhka shaybaarka ilaa kacaanka iftiinka caalamiga ah. Iyada oo horumarka degdega ah ee LED, hadda codsiga LED-ka inta badan:
-Nalalka guriga:Nalalka LED-ka, nalalka saqafka, nalalka miiska
-Nalalka ganacsiga:nalalka hoose, nalalka iftiinka, nalalka guddiyada
-Iftiinka warshadaha:nalalka macdanta, nalalka daadsan sare
-Iftiinka dibadda:nalalka waddooyinka, nalalka muuqaalka, nalalka barkadaha
-Iftiinka baabuurta:Nalalka LED-yada, nalalka maalinta, laydhka dambe
- Muujinta LED:screen advertising, Mini LED TV
-Iftiin gaar ah:UV laambad lagu daweeyo, nalka koritaanka dhirta

Maalmahan, waxaan arki karnaa LED meel kasta oo nolosheenna ah, tani waa natiijada ku dhawaad ​​​​qarnigii dadaalka, waxaan si fudud u ogaan karnaa horumarinta LED-ka sida marxaladaha 4:
1.Sahaminta hore (horraantii qarnigii 20-aad -1960-kii)
- Helitaanka electroluminescence (1907)
Injineer Ingiriis ah Henry Joseph Round ayaa markii ugu horreysay arkay korantada ku jirta crystals silicon carbide (SiC), laakiin si qoto dheer uma baranin.
Sannadkii 1927-kii, saynisyahankii Soofiyeedka Oleg Losev ayaa sii baadhay oo daabacay warqad, loo tixgeliyey inuu yahay "aabbaha aragtida LED", laakiin cilmi-baarista ayaa la joojiyay sababtoo ah dagaalkii labaad ee aduunka.

LED-kii ugu horreeyay ee wax ku ool ah wuxuu dhashay (1962)
Nick Holonyak Jr., General Electric (GE) Injineer wuxuu soo saaray iftiinka ugu horreeya ee iftiinka LED-ka (iftiin cas, walxaha GaAsP) .Tani waxay calaamad u tahay LED-ka shaybaarka ilaa ganacsi, asal ahaan loo isticmaalo tilmaamayaasha qalabka.

2. Horumarka midabka LED (1970-yadii-1990-meeyadii)
-Lidyada cagaarka iyo jaalaha ah ayaa la soo bandhigay (1970-meeyadii)
1972: M. George Craford (Ardayga Holonyak) waxa uu hindisay LED-ka jaalaha ah (10 jeer ka iftiimaya).
1980-meeyadii: Aluminium, gallium iyo arsenic (AlGaAs) waxay si weyn u wanaajiyeen waxtarka leedhka cas, kuwaas oo loo isticmaali jiray nalalka taraafigga iyo qalabka elektarooniga ah.

-Kacaanka buluuga ah ee LED (1990-meeyadii)
1993: Saynisyahan reer Japan ah Shuji Nakamura (Shuji Nakamura) oo ku jira Nichia chemical (Nichia) breakthrough gallium nitride (GaN) oo ku salaysan buluuga LED, ayaa ku guulaystay 2014 Nobel Prize ee fiisigiska

3. Caannimada LED-ka cad iyo nalka (2000s-2010s)
-Ganacsiga LED-ka cad (2000-meeyadii)
Nichia Kiimikada, Cree, Osram iyo shirkado kale ayaa bilaabay nalalka cadcad ee waxtarka sare leh si ay si tartiib tartiib ah u beddelaan nalalka iftiinka iyo iftiinka.
2006: Shirkadda American Cree waxay sii deysay 100lm / W LED ugu horeysay, oo dhaaftay waxtarka nalka.
(Sannadkii 2006 Heguang Lighting wuxuu bilaabay inuu soo saaro iftiinka biyaha hoostooda ee LED)

-LED galay nalka guud (2010s)
2010-yadii: Qiimaha LED-ka ayaa si weyn hoos ugu dhacay, dalalka adduunka oo dhanna waxay hirgeliyeen "mamnuucidda caddaanka" (sida EU-da waxay meesha ka saartay nalalka shidan ee 2012).
2014: Abaalmarinta Nobel Prize ee Fiisigiska waxaa la siiyay Isamu Akasaki, Hiroshi Amano iyo Shuji Nakamura tabarucaadka hogaanka buluuga ah.

4. Farsamada casriga ah ee LED (2020s ilaa hadda)
- LED-ka yar iyo LED-ka yar
LED-yar: Waxaa loo isticmaalaa TVS-dhamaadka sare ah (sida Apple Pro Display XDR), soo dejinta shaashadaha, iftiinka dambe ee la safeeyey.
Micro LED: pixels is-luminous, ayaa la filayaa inay bedelaan OLED (Samsung, SONY waxay soo bandhigtay alaabada nooceeda ah).

- Iftiin caqli leh iyo Li-Fi
LED Smart: heerkulka midabka la hagaajin karo, xakamaynta isku xidhka (sida Philips Hue).
Li-Fi: Isticmaalka iftiinka LED si loo gudbiyo xogta, si ka dhakhso badan Wi-Fi (shaybaarku wuxuu gaadhay 224Gbps).

- UV LED iyo codsiyada gaarka ah
Uv-c LED: Waxaa loo isticmaalaa jeermiska (sida qalabka jeermiska UV inta lagu jiro cudurka).
Koritaanka dhirta LED: spectrum la habeeyay si loo horumariyo waxtarka beeraha.

Laga soo bilaabo "iftiin tilmaame" ilaa "iftiinka guud": hufnaanta waxaa kordhay 1,000 jeer qiimahana waa la dhimay 99%, caan ka ahaanshaha LED-yada caalamiga ah waxay yareysaa boqolaal milyan oo tan oo CO₂ ah qiiqa CO₂ sanad kasta, LED ayaa beddelaya adduunka! mustaqbalka, LED waxa laga yaabaa inay wax ka beddesho bandhigga, isgaarsiinta, caafimaadka iyo warshado kale oo badan! Waanu sugi oo aragnaa!
