Te hitori whanaketanga LED

1907  I kitea e te kaiputaiao o Ingarangi a Henry Joseph Round ka kitea te whakamarama i roto i nga tioata carbide silicon i te wa e pa ana te ia.

1927  I kite ano te kaiputaiao o Ruhia a Oleg Lossew i te "Round effect" o te tuku marama.Katahi ia ka tirotirohia, ka whakamaarama atu i tenei ahuatanga

1935 I whakaputaina e te kaiputaiao Wīwī a Georges Destriau he purongo mo te ahuatanga pooti-maramatanga o te paura zinc sulfide.Hei whakamaumahara ki nga mea o mua, i whakaingoatia e ia tenei paanga ko “Lossew light” me te whakatakoto i te kupu “elector-luminescence phenomenon” i tenei ra.

1950  Ko te whakawhanaketanga o te ahupūngao semiconductor i te timatanga o te 1950s i whakarato rangahau kaupapa ariā mo nga ahuatanga pooti-whatu, i te mea ko te ahumahi semiconductor i whakarato parakore, he angiangi semiconductor doped mo te rangahau LED.

1962  I whakamahia e Nick Holon yak, Jr. raua ko SF Bevacqua o Kamupene GF nga rawa GaAsP ki te hanga i nga diodes maramara whero.Koinei te rama rama tuatahi, e kiia ana ko te tipuna o te LED hou

1965  Te hokohoko o te rama infrared rama rama, me te hokohoko o te phosphorous gallium arsenide LED whero tata

1968  I puta nga rama gallium arsenide hauota-doped

1970s  He gallium phosphate LED matomato me silicon carbide LED kōwhai.Ko te whakaurunga o nga rauemi hou ka pai ake te maamaatanga o nga rama rama me te toro atu i te hihinga kanapa o nga rama ki te karaka, te kowhai me te marama matomato.

1993  Na Nichia Chemical Company's Nakamura Shuji me etahi atu i whakawhanake i te rama gallium nitride puru kanapa tuatahi, katahi ka whakamahi i te indium gallium nitride semiconductor ki te whakaputa i nga rama ultraviolet, puru me te matomato, ma te whakamahi i te konumohe gallium indium phosphide Na te semiconductor i whakaputa nga rama tino kanapa whero me te kowhai.I hangaia ano he LED ma.

1999  Te hokohoko o nga LED me te mana whakaputa ki te 1W

I tenei wa Ko te ahumahi LED o te ao e toru nga huarahi hangarau.Ko te mea tuatahi ko te ara o te taputapu sapphire e tohuhia ana e Nichia o Hapani.I tenei wa ko te hangarau tino nui e whakamahia ana, e tino pakeke ana, engari ko tana kino ko te kore e taea te hanga i nga rahi.Ko te tuarua ko te arai hangarau arai hiko carbide carbide e tohuhia ana e te Kamupene CREE Amerika.He pai te kounga o te rauemi, engari he nui te utu o te rauemi, he uaua ki te whakatutuki i te rahi nui.Ko te tuatoru ko te hangarau o te raima hiko i hangaia e China Jingneng Optoelectronics, he painga o te utu iti, te mahi pai, me te hanga nui.
