1907  Usosayensi waseBrithani uHenry Joseph Round wathola ukuthi i-luminescence ingatholakala kumakristalu e-silicon carbide lapho kusetshenziswa okwamanje.

1927  Usosayensi waseRussia u-Oleg Lossew waphinde wabona “umphumela ojikelezayo” wokukhishwa kokukhanya.Wabe esesihlola wasichaza kabanzi lesi sigameko

1935 Usosayensi waseFrance uGeorges Destriau ushicilele umbiko mayelana ne-elector-luminescence phenomenon ye-zinc sulfide powder.Ukuze kukhunjulwe abandulele, waqamba lo mphumela ngokuthi "Ukukhanya okulahlekile" futhi waphakamisa igama elithi "i-elector-luminescence phenomenon" namuhla.

1950  Ukuthuthukiswa kwe-semiconductor physics ekuqaleni kwawo-1950 kwahlinzeka ngocwaningo oluyisisekelo lwethiyori yezenzakalo zokhetho-optical, kuyilapho imboni ye-semiconductor ihlinzeka ngamawafa ahlanzekile, ane-doped semiconductor ocwaningweni lwe-LED.

1962  U-Nick Holon yak, Jr. kanye no-SF Bevacqua we-GF Company basebenzisa izinto ze-GaAsP ukwenza ama-diode akhipha ukukhanya okubomvu.Lona ukukhanya kwe-LED yokuqala ebonakalayo, ethathwa njengokhokho we-LED yesimanje

1965  Ukuhweba kwe-infrared light emit LED, kanye nokudayiswa kwe-red phosphorous gallium arsenide LED maduze

1968  Kwavela ama-LED e-gallium arsenide ane-nitrogen-doped

1970s  Kukhona ama-LED aluhlaza we-gallium phosphate kanye nama-LED aphuzi we-silicon carbide.Ukwethulwa kwezinto ezintsha kuthuthukisa ukusebenza kahle okukhanyayo kwama-LED futhi kunwebe i-spectrum ekhanyayo yama-LED kuya ekukhanyeni okusawolintshi, okuphuzi nokuluhlaza.

1993  UNakamura Shuji weNkampani ye-Nichia Chemical Company kanye nabanye bakhe i-LED yokuqala ekhanyayo eluhlaza okwesibhakabhaka ye-gallium nitride, base besebenzisa i-indium gallium nitride semiconductor ukukhiqiza ama-ultra-bright ultraviolet, blue and green LEDs, besebenzisa i-aluminium gallium indium phosphide I-semiconductor ikhiqize ama-LED agqamile kakhulu abomvu naphuzi.I-LED emhlophe nayo yaklanywa.

1999  Ukuhweba kwama-LED anamandla aphumayo afika ku-1W

Okwamanje Imboni ye-LED yomhlaba wonke inemizila emithathu yobuchwepheshe.Owokuqala umzila wesafire ongaphansi omelwe iNichia yaseJapan.Njengamanje iwubuchwepheshe obusetshenziswa kakhulu futhi obuvuthwe kakhulu, kodwa ububi bayo ukuthi abukwazi ukwenziwa ngosayizi abakhulu.Owesibili umzila we-silicon carbide substrate we-LED omelwe yi-American CREE Company.Ikhwalithi yezinto ezibonakalayo inhle, kodwa izindleko zayo ezibonakalayo ziphezulu futhi kunzima ukufeza usayizi omkhulu.Okwesithathu ubuchwepheshe be-silicon substrate LED obusungulwe yi-China Jingneng Optoelectronics, obunobuhle bezindleko eziphansi zezinto ezibonakalayo, ukusebenza kahle, kanye nokukhiqiza ngezinga elikhulu.
