Ci gaban LED

Ci gaban LED ya fito ne daga binciken dakin gwaje-gwaje zuwa juyin juya halin hasken duniya. Tare da saurin haɓaka LED, yanzu aikace-aikacen LED galibi zuwa:
- Hasken gida:LED kwararan fitila, rufi fitilu, tebur fitilu
- Hasken kasuwanci:hasken wuta, fitilu, fitilu na panel
- Hasken masana'antu:ma'adinai fitilu, high zubar fitilu
- Hasken waje:fitulun titi, fitilun shimfidar wuri, fitulun tafkin
- Hasken mota:LED fitilolin mota, hasken rana, fitulun wutsiya
- Nuni LED:allon talla, Mini LED TV
- Haske na musamman:UV curing fitila, shuka girma fitila

A zamanin yau, za mu iya ganin LED a ko'ina cikin rayuwar mu, wannan shi ne sakamakon kusan karni na kokarin, za mu iya kawai mu san ci gaban LED kamar yadda busa 4 matakai:
1.Bincike na farko (farkon karni na 20 -1960)
-Ganowar Electroluminescence (1907)
Injiniyan Biritaniya Henry Joseph Round ya fara ganin electroluminescence akan lu'ulu'u na silicon carbide (SiC), amma bai yi nazari a zurfi ba.
A cikin 1927, masanin kimiyyar Soviet Oleg Losev ya kara yin nazari kuma ya buga takarda, wanda aka yi la'akari da shi a matsayin "uban ka'idar LED", amma binciken ya katse saboda yakin duniya na biyu.

-An haifi LED mai amfani na farko (1962)
Nick Holonyak Jr., General Electric (GE) Injiniyan Ƙirƙirar haske mai haske na farko da aka gani (hasken ja, kayan GaAsP) .Wannan yana nuna alamar LED daga dakin gwaje-gwaje zuwa tallace-tallace, wanda aka fara amfani da shi don alamun kayan aiki.

2. Ci gaban LED mai launi (1970s-1990s)
-An gabatar da ledojin kore da rawaya (1970s)
1972: M. George Craford (dalibi na Holonyak) ya kirkiro LED mai launin rawaya (sau 10 mafi haske).
1980s: Aluminum, gallium da arsenic (AlGaAs) kayan sun inganta ingantaccen jajayen ledoji, waɗanda aka yi amfani da su a cikin fitilun zirga-zirga da kayan lantarki.

-Blue LED juyin juya hali (1990s)
1993: Masanin kimiyya dan kasar Japan Shuji Nakamura (Shuji Nakamura) a cikin Nichia chemical (Nichia) nasara gallium nitride (GaN) blue LED, ya lashe kyautar Nobel ta 2014 a kimiyyar lissafi.Wannan alamar Blue LED + phosphor = farin LED, yana shimfiɗa harsashin hasken LED na zamani.

3. Shahararriyar farin LED da haske (2000s-2010s)
-Farin tallace-tallace na LED (2000s)
Nichia Chemical, Cree, Osram da sauran kamfanoni sun ƙaddamar da manyan ledoji masu inganci don maye gurbin fitilun fitilu a hankali.
2006: Kamfanin Cree na Amurka ya fito da 100lm / W LED na farko, wanda ya zarce ingancin fitilar fitila.
(A cikin 2006 Heguang Lighting ya fara samar da hasken ruwa na LED)

-LED zuwa haske na gaba ɗaya (2010s)
2010s: Farashin LED ya ragu sosai, kuma ƙasashe a duniya sun aiwatar da "hana kan fararen fata" (kamar EU ta fitar da fitilu masu haske a cikin 2012).
2014: Nobel Prize in Physics da aka baiwa Isamu Akasaki, Hiroshi Amano da Shuji Nakamura don gudunmuwa ga shuɗi.

4. Fasahar LED na zamani (2020s har yanzu)
- Mini LED & Micro LED
Mini LED: Ana amfani da shi don manyan TVS (kamar Apple Pro Display XDR), yana fitar da fuska, ƙarin ingantaccen hasken baya.
Micro LED: pixels masu haske, ana tsammanin maye gurbin OLED (Samsung, SONY sun ƙaddamar da samfuran samfuri).

- Haske mai hankali da Li-Fi
Smart LED: daidaitacce zazzabi mai launi, sarrafa sadarwar (kamar Philips Hue).
Li-Fi: Amfani da hasken LED don isar da bayanai, da sauri fiye da Wi-Fi (labarin ya kai 224Gbps).

- UV LED da aikace-aikace na musamman
Uv-c LED: Ana amfani da shi don haifuwa (kamar kayan aikin kashe UV yayin annoba).
LED girma shuka: Musamman bakan don inganta aikin gona yadda ya dace.

Daga "hasken nuni" zuwa "hasken al'ada": ana haɓaka haɓaka ta sau 1,000 kuma an rage farashin ta 99%, yaduwar LED ta duniya tana rage ɗaruruwan miliyoyin ton na iskar CO₂ kowace shekara, LED yana canza duniya! a nan gaba, LED na iya canza fasalin nuni, sadarwa, likitanci da sauran masana'antu da yawa! Za mu jira mu gani!
