Ƙirƙirar LEDs (diodes masu fitar da haske) wani tsari ne mai matakai da yawa wanda ya ƙunshi gudummawar masana kimiyya da yawa. Anan akwai wasu mahimman lokutan tarihi a cikin ƙirƙirar LEDs:
Ka'idar farko da gwaje-gwaje:
1907:Masanin kimiyar Burtaniya HJ Round ya fara lura cewa na'ura mai sarrafa silikon carbide (SiC) tana fitar da haske lokacin da ake amfani da wutar lantarki. Wannan shi ne farkon abin da aka yi rikodin na'urar lantarki na kayan semiconductor.
1920s:Masanin kimiyyar kasar Rasha Oleg Losev ya kara yin nazari kan lamarin kuma ya buga wata takarda kan ka’idojin LED a shekarar 1927, amma hakan bai jawo hankalin jama’a ba a lokacin.
Haɓaka LEDs masu amfani:
1962:Nick Holonyak Jr., injiniyan injiniya da ke aiki a General Electric (GE) a lokacin, ya ƙirƙira na farko mai amfani da haske mai haske mai haske (LED LED). Holonyak da aka sani da "Uban LEDs".
1972:M. George Craford, ɗalibin Holonyak, ya ƙirƙiri LED mai launin rawaya na farko kuma ya inganta haske sosai na ledojin ja da lemu. Ya yi gyare-gyare bisa gallium nitride phosphorus (GaAsP) abu don ƙara haske na LEDs sau goma.
1970s da 1980s: Ci gaban fasaha ya haifar da ƙirƙirar LEDs a cikin ƙarin launuka, gami da kore, rawaya, da lemu.
Hasken LED mai haske:
1990s:Masana kimiyya a Hitachi da Nichia, musamman Shuji Nakamura, sun ƙirƙira manyan LEDs masu haske. Wannan babban ci gaba ne ta amfani da kayan gallium nitride (GaN). Ƙirƙirar LEDs masu launin shuɗi ya sanya nuni mai cikakken launi da fararen LEDs mai yiwuwa.
2014:Shuji Nakamura, Isamu Akasaki, da Hiroshi Amano sun sami lambar yabo ta Nobel a fannin Physics saboda aikin da suka yi akan na'urar ledoji mai shuɗi.
Haɓaka Farin LEDs:
Farar LEDs yawanci ana ƙirƙira su ta hanyar haɗa ledojin shuɗi tare da phosphor. Hasken shuɗi na LED mai shuɗi yana faranta wa phosphor rai, wanda sai ya fitar da hasken rawaya, kuma haɗuwa da biyun yana haifar da farin haske.
Ci gaba a cikin fasahar LED ya haifar da nau'in launi na LED ba kawai a cikin kewayon da ake iya gani ba, har ma a cikin ultraviolet da infrared. A yau, ana amfani da LEDs a aikace-aikace iri-iri, gami da nuni, haske, fitilun nuni, da sadarwa.
