1907  Rasaense oa Brithani Henry Joseph Round o fumane hore leseli le ka fumanoa ka har'a likristale tsa silicon carbide ha ho sebelisoa hona joale.

1927  Rasaense oa Lerussia Oleg Lossew o ile a boela a hlokomela “Phello e potolohileng” ea ho ntšoa ha leseli.Eaba o hlahloba le ho hlalosa ketsahalo ena ka botlalo

1935 Rasaense oa Lefora Georges Destriau o ile a hatisa tlaleho mabapi le ketsahalo ea khetho-luminescence ea phofo ea zinc sulfide.E le ho ikhopotsa ba pele ho moo, o ile a reha phello ena "Leseli le lahleheloang ke leseli" 'me a fana ka tlhahiso ea lentsoe "elector-luminescence phenomenon" kajeno.

1950  Nts'etsopele ea fisiks ea semiconductor mathoasong a lilemo tsa bo-1950 e ile ea fana ka lipatlisiso tsa theoretical bakeng sa liketsahalo tsa likhetho-optical, athe indasteri ea semiconductor e ne e fana ka liphaephe tse hloekileng tsa semiconductor bakeng sa lipatlisiso tsa LED.

1962  Nick Holon yak, Jr. le SF Bevacqua ba GF Company ba ile ba sebelisa thepa ea GaAsP ho etsa li-diode tse khubelu tse ntšang khanya.Ena ke khanya ea pele e bonahalang ea LED, e nkoang e le moholo-holo oa LED ea kajeno

1965  Khoebo ea infrared light emitting LED, le khoebo ea red phosphorous gallium arsenide LED haufinyane.

1968  Ho ile ha hlaha li-LED tsa gallium arsenide tse nang le naetrojene

1970s  Ho na le li-LED tse tala tsa gallium phosphate le li-LED tse mosehla tsa silicon carbide.Kenyelletso ea lisebelisoa tse ncha e ntlafatsa ts'ebetso e khanyang ea li-LED le ho holisa khanya e khanyang ea mabone a lamunu, a mosehla le a botala.

1993  Nichia Chemical Company's Nakamura Shuji le ba bang ba ile ba hlahisa LED ea pele e khanyang ea gallium nitride LED, 'me ka mor'a moo ba sebelisa indium gallium nitride semiconductor ho hlahisa li-ultraviolet tse khanyang, tse putsoa le tse tala tsa LED, li sebelisa aluminium gallium indium phosphide Semiconductor e hlahisitse li-LED tse khanyang haholo tse khubelu le tse mosehla.LED e tšoeu e boetse e entsoe.

1999  Khoebo ea li-LED tse nang le matla a tsoang ho 1W

Hajoale Indasteri ea lefats'e ea LED e na le litsela tse tharo tsa tekheniki.Ea pele ke tsela ea sapphire substrate e emeloang ke Nichia ea Japane.Hona joale ke theknoloji e sebelisoang ka ho fetisisa le e hōlileng ka ho fetisisa, empa bothata ba eona ke hore e ke ke ea etsoa ka boholo bo boholo.Ea bobeli ke tsela ea theknoloji ea silicon carbide substrate LED e emeloang ke American CREE Company.Boleng ba thepa bo botle, empa litšenyehelo tsa eona tsa thepa li phahame 'me ho thata ho finyella boholo bo boholo.Ea boraro ke theknoloji ea silicon substrate LED e qapiloeng ke China Jingneng Optoelectronics, e nang le melemo ea theko e tlase ea thepa, ts'ebetso e ntle, le tlhahiso e kholo.
