1907  Ua ʻike ka ʻepekema Pelekane ʻo Henry Joseph Round e hiki ke loaʻa ka luminescence i loko o nā kristal carbide silika ke hoʻohana ʻia ke au.

1927  Ua nānā hou ka ʻepekema Lūkini ʻo Oleg Lossew i ka "Round effect" o ka hoʻokuʻu māmā.A laila, nānā a wehewehe ʻo ia i kēia ʻano me nā kikoʻī

1935 Ua hoʻopuka ka mea ʻepekema Farani ʻo Georges Destriau i kahi hōʻike e pili ana i ke ʻano koho-luminescence o ka pauka zinc sulfide.No ka hoʻomanaʻo ʻana i nā mea ma mua, ua kapa ʻo ia i kēia hopena ʻo "Lossew light" a hoʻopuka i ka huaʻōlelo "elector-luminescence phenomenon" i kēia lā.

1950  ʻO ka hoʻomohala ʻana i ka physics semiconductor i nā makahiki 1950 mua i hāʻawi i ka noiʻi kumu kumu no nā hanana koho koho-optical, ʻoiai ua hāʻawi ka ʻoihana semiconductor i nā wafers semiconductor maʻemaʻe, doped no ka noiʻi LED.

1962  Ua hoʻohana ʻo Nick Holon yak, Jr. a me SF Bevacqua o GF Company i nā mea GaAsP e hana i nā diodes ʻulaʻula.ʻO kēia ka LED kukui ʻike mua ʻia, i manaʻo ʻia ʻo ke kupuna o nā LED hou

1965  ʻO ka hoʻolaha ʻana o ke kukui uila infrared LED, a me ka hoʻolaha ʻana o ka ʻulaʻula phosphorous gallium arsenide LED koke.

1968  Ua ʻike ʻia nā LED gallium arsenide nitrogen-doped

1970s  Aia nā kukui ʻōmaʻomaʻo gallium phosphate a me nā LED melemele silicon carbide.ʻO ka hoʻokomo ʻana i nā mea hou e hoʻomaikaʻi i ka pono o nā LED a hoʻonui i ka spectrum kukui o nā LED i ka ʻalani, melemele a me ka ʻōmaʻomaʻo.

1993  Na Nichia Chemical Company's Nakamura Shuji a me nā mea ʻē aʻe i hoʻomohala i ka gallium nitride LED mua loa, a laila hoʻohana i ka indium gallium nitride semiconductor no ka hana ʻana i nā kukui ultraviolet ultra-bright, uliuli a me nā kukui ʻōmaʻomaʻo, me ka hoʻohana ʻana i ka alumini gallium indium phosphide Ua hana ka semiconductor i nā LED ʻulaʻula a me ka melemele.Ua hoʻolālā pū ʻia kahi LED keʻokeʻo.

1999  ʻO ka hoʻolaha ʻana o nā LED me ka mana puka a hiki i 1W

I kēia manawa ʻEkolu mau ala ʻenehana ka honua LED ʻoihana.ʻO ka mua, ʻo ia ke ala sapphire substrate i hōʻike ʻia e Nichia o Iapana.I kēia manawa ʻo ia ka ʻenehana i hoʻohana nui ʻia a ʻoi loa, akā ʻo kona hemahema ʻaʻole hiki ke hana ʻia i nā nui nui.ʻO ka lua, ʻo ia ke ala ʻenehana silicon carbide substrate LED i hōʻike ʻia e American CREE Company.Maikaʻi ka maikaʻi o ka waiwai, akā he kiʻekiʻe kona kumukūʻai a paʻakikī ke hoʻokō i ka nui nui.ʻO ke kolu, ʻo ia ka ʻenehana silicon substrate LED i hana ʻia e China Jingneng Optoelectronics, nona nā pōmaikaʻi o ke kumu kūʻai haʻahaʻa, hana maikaʻi, a me ka hana nui.
