1907dii  Saynis yahan Ingiriis ah oo lagu magacaabo Henry Joseph Round ayaa daaha ka qaaday in luminescence laga heli karo crystals carbide silicon marka hadda la isticmaalo.

1927kii  Saynisyahanka Ruushka Oleg Lossew ayaa mar kale arkay "saamaynta wareega" ee iftiinka iftiinka.Dabadeed wuxuu baadhay oo si faahfaahsan uga warramay dhacdadan

1935kii Saynisyahanka Faransiiska Georges Destriau ayaa daabacay warbixin ku saabsan ifafaalaha doorashada-luminescence ee budada zinc sulfide.Si loo xuso kuwii ka horreeyay, wuxuu saamayntan ugu magac daray "Lossew Light" wuxuuna soo jeediyay ereyga "iftiin-doorasho-luminescence" maanta.

1950kii  Horumarinta fiisigiska semiconductor horraantii 1950-meeyadii waxay bixisay cilmi-baaris aasaasi ah oo loogu talagalay ifafaale-doorasho-optical, halka warshadaha semiconductor-ka ay bixiyeen wafers semiconductor saafi ah, doped semiconductor for cilmi-baarista LED

1962kii  Nick Holon yak, Jr. iyo SF Bevacqua oo ka tirsan Shirkadda GF waxay isticmaaleen agabka GaAsP si ay u sameeyaan diodes iftiin-casa leh.Tani waa LED-kii ugu horreeyay ee la arki karo, oo loo arko awoowaha LED-ka casriga ah

1965kii  Ka-ganacsiga LED-ka soo baxaya iftiinka infrared-ka, iyo ganacsiyaynta gallium arsenide LED

1968kii  Naytrogen-doped gallium arsenide LEDs ayaa soo muuqday

1970kiis  Waxaa jira gallium fosfateed LEDs cagaaran iyo silikoon carbide LEDs huruud ah.Soo bandhigida alaabada cusub waxay hagaajinaysaa waxtarka iftiinka iftiinka LED-yada waxayna kordhisaa iftiinka iftiinka ee LED-yada ilaa orange, huruud iyo cagaar.

1993kii  Shirkadda Kiimikada Nichia ee Nakamura Shuji iyo kuwa kale waxay soo saareen gallium nitride LED-kii ugu horreeyay ee dhalaalaya buluugga, ka dibna waxay isticmaaleen semiconductor indium gallium nitride semiconductor si ay u soo saaraan ultraviolet ultraviolet, buluug iyo cagaaran, iyadoo la adeegsanayo aluminium gallium indium phosphide Semiconductor-ku wuxuu soo saaray LEDs aad u dhalaalaya oo casaan ah.LED cad ayaa sidoo kale la naqshadeeyay.

1999kii  Ka ganacsiga LED-yada leh awoodda wax soo saarka ilaa 1W

Hadda Warshadaha LED-yada caalamiga ah waxay leeyihiin saddex waddo oo farsamo.Midda kowaad waa dariiqa sapphire substrate-ka oo uu matalo Nichia Japan.Hadda waa tignoolajiyada ugu isticmaalka badan uguna qaan-gaadhka ah, laakiin dhibteeda ayaa ah in aan lagu samayn karin qiyaaso waaweyn.Midda labaad waa marinka tignoolajiyada LED-ka ee silicon carbide substrate oo ay mataleyso Shirkadda American CREE.Tayada maaddadu waa wanaagsan tahay, laakiin qiimaha maaddadu waa mid sarreeya wayna adagtahay in la gaaro cabbir weyn.Midda saddexaad waa tignoolajiyada silikoon substrate LED ee ay ikhtiraacday Shiinaha Jingneng Optoelectronics, kaas oo leh faa'iidooyinka kharash yar, wax qabad wanaagsan, iyo wax soo saar ballaadhan.
