1907  Na iloa e le saienitisi Peretania o Henry Joseph Round e mafai ona maua le luminescence i tioata carbide silicon pe a faʻaaogaina le vai.

1927  Na toe matauina foi e le saienitisi Rusia o Oleg Lossew le "Aafiaga lapotopoto" o le faʻamalama.Ona ia suʻesuʻeina lea ma faʻamatala atili lenei mea mataʻutia

1935 Na lomia e le saienitisi Farani o Georges Destriau se lipoti e uiga i le faiga palota-luminescence phenomenon o le zinc sulfide powder.Ina ia faʻamanatuina muamua, na ia faʻaigoaina lenei aafiaga "Lossew light" ma faʻatulagaina le faaupuga "elector-luminescence phenomenon" i aso nei.

1950  O le atinaʻeina o le fisiki semiconductor i le amataga o le 1950 na tuʻuina atu ai suʻesuʻega faʻavae mo tagata palota-optical phenomena, ae o le alamanuia semiconductor na tuʻuina atu mama, doped semiconductor wafers mo suʻesuʻega LED.

1962  Nick Holon yak, Jr. ma SF Bevacqua o le Kamupani GF na fa'aogaina mea GaAsP e fai ai diodes mumu moli.O le ulua'i moli va'aia lea o le LED, ua ta'ua o le tua'a o LED fa'aonaponei

1965  Fa'atauga o le moli fa'avevela mumu, ma le fa'atauina o le gallium arsenide mumu mumu phosphorous LED vave.

1968  Na fa'aalia le gallium arsenide fa'apipi'i nitrogen

1970s  E iai gallium phosphate lanu meamata LED ma silicon carbide LED samasama.O le fa'aofiina o mea fou e fa'aleleia atili ai le fa'amalamalamaga lelei o LED ma fa'alautele atu le fusi o alaleo o LED i moli, samasama ma lanu meamata.

1993  Nichia Chemical Company's Nakamura Shuji ma isi na atiina ae le uluai moli lanu moana gallium nitride LED, ona faʻaaogaina lea o le indium gallium nitride semiconductor e gaosia ai le ultra-bright ultraviolet, lanumoana ma le lanumeamata, faʻaaogaina le alumini gallium indium phosphide O le semiconductor na gaosia ai le lanu mumu ma le samasama sili.Sa mamanuina foi se LED paepae.

1999  Fa'atauva'a o LED ma le mana fa'aola e o'o atu ile 1W

I le taimi nei Le lalolagi LED alamanuia e tolu auala faʻapitoa.Muamua o le safaira substrate auala o loʻo faʻatusalia e Iapani Nichia.O le taimi nei o le tekinolosi sili ona faʻaaogaina ma sili ona matua, ae o lona faʻaletonu e le mafai ona faia i lapopoa tetele.O le lona lua o le silicon carbide substrate LED technology auala o loʻo faʻatusalia e American CREE Company.O le tulaga lelei o meafaitino e lelei, ae o lona tau o meafaitino e maualuga ma e faigata ona ausia le lapoa tele.O le lona tolu o le silicon substrate LED technology na fatuina e China Jigneng Optoelectronics, lea e iai le lelei o le tau maualalo o meafaitino, lelei le faʻatinoina, ma le gaosiga tele.
