Xyoo 1907  Tus kws tshawb fawb Askiv Henry Joseph Round tau tshawb pom tias luminescence tuaj yeem pom nyob rau hauv silicon carbide crystals thaum siv tam sim no.

Xyoo 1927  Lavxias tus kws tshawb fawb Oleg Lossew ib zaug ntxiv tau pom "Round effect" ntawm lub teeb emission.Tom qab ntawd nws tau tshuaj xyuas thiab piav qhia txog qhov tshwm sim no kom ntxaws ntxiv

Xyoo 1935 Tus kws tshawb fawb Fab Kis Georges Destriau tau tshaj tawm tsab ntawv tshaj tawm txog kev xaiv tsa-luminescence tshwm sim ntawm zinc sulfide hmoov.Txhawm rau ua kev nco txog cov neeg ua ntej, nws tau muab cov txiaj ntsig no hu ua "Lossew light" thiab tau tshaj tawm lo lus "kev xaiv tsa-luminescence phenomenon" niaj hnub no.

Xyoo 1950  Txoj kev loj hlob ntawm semiconductor physics nyob rau hauv thaum ntxov 1950s muab theoretical hauv paus kev tshawb fawb rau elector-optical phenomena, thaum lub semiconductor kev lag luam muab ntshiab, doped semiconductor wafers rau LED kev tshawb fawb.

Xyoo 1962  Nick Holon yak, Jr. thiab SF Bevacqua ntawm GF Lub Tuam Txhab siv GaAsP cov ntaub ntawv los ua lub teeb liab-emitting diodes.Qhov no yog thawj lub teeb pom kev LED, suav tias yog cov poj koob yawm txwv ntawm niaj hnub LED

Xyoo 1965  Kev lag luam ntawm lub teeb infrared emitting LED, thiab kev lag luam ntawm liab phosphorous gallium arsenide LED sai sai

Xyoo 1968  Nitrogen-doped gallium arsenide LEDs tshwm sim

Xyoo 1970s  Muaj gallium phosphate ntsuab LEDs thiab silicon carbide daj LEDs.Kev taw qhia ntawm cov ntaub ntawv tshiab txhim kho lub luminous efficiency ntawm LEDs thiab ncua lub luminous spectrum ntawm LEDs rau txiv kab ntxwv, daj thiab ntsuab teeb.

Xyoo 1993  Nichia Chemical Company's Nakamura Shuji thiab lwm tus tau tsim thawj lub teeb xiav gallium nitride LED, thiab tom qab ntawd siv indium gallium nitride semiconductor los tsim ultra-ci ultraviolet, xiav thiab ntsuab LEDs, siv aluminium gallium indium phosphide Lub semiconductor tsim super ci liab thiab daj LEDs.Ib tug dawb LED kuj tsim.

Xyoo 1999  Kev lag luam ntawm LEDs nrog cov zis hluav taws xob txog li 1W

Tam sim no Kev lag luam thoob ntiaj teb LED muaj peb txoj hauv kev.Thawj yog txoj kev sapphire substrate sawv cev los ntawm Nyiv lub Nichia.Nws yog tam sim no siv ntau tshaj plaws thiab paub tab technology, tab sis nws qhov tsis zoo yog tias nws tsis tuaj yeem ua rau ntau qhov loj.Qhov thib ob yog silicon carbide substrate LED technology txoj kev sawv cev los ntawm American CREE Company.Cov khoom siv zoo yog qhov zoo, tab sis nws cov nqi khoom yog siab thiab nws nyuaj rau ua tiav qhov loj.Qhov thib peb yog silicon substrate LED tshuab tsim los ntawm Tuam Tshoj Jingneng Optoelectronics, uas muaj qhov zoo ntawm cov khoom siv qis, kev ua haujlwm zoo, thiab kev tsim khoom loj.
