1907  Wasayansi waku Britain Henry Joseph Round adapeza kuti luminescence imatha kupezeka mu silicon carbide makhiristo akagwiritsidwa ntchito pano.

1927  Wasayansi wa ku Russia Oleg Lossew anaonanso “kuzungulira kwa mpweya” wa mpweya.Kenako anaunikanso n’kufotokoza mwatsatanetsatane chochitikachi

1935 Wasayansi wa ku France dzina lake Georges Destriau adafalitsa lipoti lonena za chinthu cha elector-luminescence cha zinc sulfide powder.Kukumbukira omwe adatsogolera, adatcha izi "Kuwala kotayika" ndipo adapereka mawu akuti "elector-luminescence phenomenon" lero.

1950  Kukula kwa semiconductor physics koyambirira kwa zaka za m'ma 1950 kunapereka kafukufuku wowunikira pazochitika za elector-optical, pomwe makampani opanga zida zopangira zida zamagetsi amapereka zowotcha zoyera, zopangidwa ndi doped semiconductor pakufufuza kwa LED.

1962  Nick Holon yak, Jr. ndi SF Bevacqua a GF Company adagwiritsa ntchito zida za GaAsP kupanga ma diode ofiira otulutsa kuwala.Uwu ndiye kuwala koyamba kowoneka kwa LED, komwe kumawonedwa ngati kholo lamakono la LED

1965  Kugulitsa kwa infrared light emitting LED, ndi malonda a red phosphorous gallium arsenide LED posachedwa

1968  Ma LED opangidwa ndi nayitrogeni a gallium arsenide adawonekera

1970s  Pali ma LED obiriwira a gallium phosphate ndi ma LED achikasu a silicon carbide.Kukhazikitsidwa kwa zida zatsopano kumapangitsa kuti ma LED aziwoneka bwino komanso amawonjezera kuwala kwa ma LED mpaka kuwala kowala, chikasu ndi kobiriwira.

1993  Nakamura Shuji wa kampani ya Nichia Chemical Company ndi ena anapanga LED yowala kwambiri ya buluu ya gallium nitride, kenako anagwiritsa ntchito indium gallium nitride semiconductor kuti apange ma ultraviolet, buluu ndi obiriwira a LED, pogwiritsa ntchito aluminium gallium indium phosphide The semiconductor inapanga ma LED ofiira owala kwambiri ndi achikasu.LED yoyera idapangidwanso.

1999  Kugulitsa ma LED okhala ndi mphamvu zotulutsa mpaka 1W

Panopa Makampani opanga ma LED padziko lonse lapansi ali ndi njira zitatu zaukadaulo.Yoyamba ndi njira ya safiro yoimiridwa ndi Nichia waku Japan.Pakalipano ndi teknoloji yomwe imagwiritsidwa ntchito kwambiri komanso yokhwima kwambiri, koma kuipa kwake ndikuti sikungapangidwe mumiyeso yayikulu.Yachiwiri ndi njira yaukadaulo ya silicon carbide ya LED yoimiridwa ndi American CREE Company.Ubwino wazinthu ndi wabwino, koma mtengo wake wazinthu ndi wokwera ndipo ndizovuta kukwaniritsa kukula kwakukulu.Chachitatu ndi ukadaulo wa silicon substrate LED wopangidwa ndi China Jingneng Optoelectronics, womwe uli ndi zabwino zake zotsika mtengo, magwiridwe antchito abwino, komanso kupanga kwakukulu.
