1907  Musayendisiti wekuBritain Henry Joseph Round akawana kuti luminescence inogona kuwanikwa musilicon carbide makristasi kana ikozvino yaiswa.

1927  Musayendisiti wokuRussia Oleg Lossew akacherechedza zvakare "Round effect" yekubuda kwechiedza.Ipapo akaongorora uye akatsanangura chiitiko ichi zvakadzama

1935 Musayendisiti wechiFrench Georges Destriau akabudisa mushumo pamusoro pesarudzo-luminescence phenomenon ye zinc sulfide powder.Kurangarira vakatangira, akatumidza chiitiko ichi "Kurasika mwenje" uye akaronga izwi rekuti "elector-luminescence phenomenon" nhasi.

1950  Kuvandudzwa kwesemiconductor fizikisi mukutanga kwema1950 kwakapa theoretical hwaro hwekutsvagisa kwesarudzo-optical phenomena, nepo semiconductor indasitiri yaipa yakachena, doped semiconductor wafers yekutsvagisa LED.

1962  Nick Holon yak, Jr. uye SF Bevacqua veGF Company vakashandisa zvinhu zveGaAsP kugadzira dzvuku-emitting diodes.Iyi ndiyo yekutanga kuoneka mwenje LED, inoonekwa setateguru wemazuva ano LED

1965  Kutengeserana kweiyo infrared mwenje inoburitsa LED, uye kutengeswa kwered phosphorous gallium arsenide LED munguva pfupi iri kutevera.

1968  Nitrogen-doped gallium arsenide maLED akaonekwa

1970s  Kune gallium phosphate girini LEDs uye silicon carbide yellow LEDs.Kuunzwa kwezvinhu zvitsva kunonatsiridza kupenya kwe LED uye kunowedzera inopenya spectrum ye LEDs kune orenji, yero uye yegirinhi mwenje.

1993  Nichia Chemical Company's Nakamura Shuji nevamwe vakagadzira yekutanga kupenya yeblue gallium nitride LED, ndokuzoshandisa indium gallium nitride semiconductor kugadzira Ultra-inopenya ultraviolet, bhuruu uye girini maLED, vachishandisa aluminium gallium indium phosphide Iyo semiconductor yakagadzira super inopenya tsvuku uye yero maLED.A chena LED yakagadzirwawo.

1999  Kutengeserana kwema LED ane simba rekubuda kusvika ku1W

Parizvino Indasitiri yepasi rose ye LED ine nzira nhatu dzehunyanzvi.Yekutanga inzira yesafire substrate inomiririrwa neJapan Nichia.Parizvino ndiyo inonyanya kushandiswa uye yakanyanya kukura tekinoroji, asi chakashata ndechekuti haigone kugadzirwa muhukuru hukuru.Yechipiri ndiyo silicon carbide substrate LED tekinoroji nzira inomiririrwa neAmerican CREE Kambani.Hunhu hwezvinhu hwakanaka, asi mutengo wayo wezvinhu wakakwira uye zvakaoma kuwana hukuru hukuru.Yechitatu ndiyo silicon substrate LED tekinoroji yakagadzirwa neChina Jingneng Optoelectronics, ine zvakanakira mutengo wakaderera wezvinhu, kuita kwakanaka, uye hukuru hwekugadzira.
