Dab Tsi Teeb Zeem Duab Ntse?

Ib lub teeb uas muaj teeb ci tawm ( LED ) yog lub zog tsim hluav taws xob tsim kev tsim lub teeb. Siv lub semiconductor Circuit Court hu ua diode , ib qho LED ua lub teeb ntau xim, nyob ntawm cov khoom siv hauv nws cov khoom siv. Cov LEDs muaj ntau qhov kev cog lus, txhim khu kev qha, thiab ntev ntev tshaj qhov muag teeb qhov muag teeb thiab siv ib feem ntawm lub zog. Ua ntej siv rau xyoo 1970, cov LEDs pib nce nrov thiab ua haujlwm nyob rau tiam 21st century. Lub teeb-emitting diode tej zaum nws yuav hloov lub teeb qhov muag raws li kev siv tshuab ua rau nws pheej yig dua thiab ntau dua.

LEDs ua haujlwm ntawm cov khoom hu ua electroluminescence, uas qee cov ntaub ntawv tsim hluav taws xob thaum muaj hluav taws xob tam sim no. Cov nyhuv tau xub sau tseg rau xyoo 1907, thiab cov tshuab LED tau tsim tsa los ntawm Lavxias teb sab tus kws tshawb fawb Oleg Losev ob xyoos tom qab ntawd. Tus nqi siab ntawm cov ntaub ntawv txhais tau hais tias cov ntawv siv rau lub teeb-emitting diode tsis tsim kom txog rau thaum xyoo 1960. Los ntawm xyoo 1970, lub teeb liab me me raug siv hauv cov khoom siv me me xws li watches thiab calculators thiab ua cov ntsuas hluav taws xob rau cov cuab yeej loj. Cov kev kho tshiab hauv kev siv tshuab semiconductor muab LEDs dav ntau yam thiab cov kev siv rau thaum kaj ntug ntawm lub xyoo pua 21st.

Ib qho diode yog ib qhov kev sib cog lus uas tswj cov khoom siv hluav taws xob uas siv cov khoom siv rau semiconducting xws li silicon. Ib qho hluav taws xob-emitting diode siv cov cuab yeej no los muab ntxig rau electrons rau kev tsim lub teeb. Cov txheej txheem no muaj ntau lub zog siv zog tshaj qhov teeb ci qhov muag teeb, lub ntsiab lus me ntsis hluav taws xob khib nyiab, thiab lub diode yuav kav ntev tshaj li lub teeb. Cov thawj LEDs tau muaj kev txwv ntau, xim liab, xiav, thiab daj. Cov kev kho tshiab hauv kev siv tshuab tau nce lub ci ci ntawm LEDs thiab muab lawv cov xim thoob plaws lub spectrum.

LED teeb muaj ntau kim los tsim dua li cov qhov muag teeb lossis cov qhov muag teeb pom kev zoo, tiam sis lawv lub neej ntev ntev ua rau lawv zoo rau qhov chaw uas hloov qhov muag teeb. Lawv feem ntau yog siv sab hauv thiab sab nrauv rau cov tsheb, nkoj, thiab cov aircraft. Muaj ntau cov tsheb khiav lag luam, txoj kev teeb, thiab cov paib kuj ntiav ib co qauv ntawm lub teeb tawm ntawm lub teeb tawm. Cov LEDs muab kev teeb ci kom pom kev cov ntxaij ntawm cov laptops, xov tooj, thiab cov khoom siv xovtooj. Los ntawm kev ntxov xyoo 2010, lawv tau siv ntau ntau ntawm cov hniav thiab cov tswv yim siv teeb pom kev zoo.

Lub teeb-emitting diode tsis muaj qee qhov tsis zoo. Thaum siab muaj zog, nws tau nquag ua kom poob zoo, ib qho khoom hluav taws xob xa hluav taws xob hu rau droop. Nws tuaj yeem ua raws li cov kev hloov hauv kub, qhov siab, thiab theem tam sim no. Kev tsim ntawm cov teeb dawb teeb tau qeeb ntau xyoo vim hais tias ntawm cov kev txwv ntawm LED spectrum, cov khoom ntawm cov ntaub ntawv semiconductor. Raws li cov kev txwv no raug kov los ntawm kev siv cuab yeej technology, cov cuab yeej technology technology yuav tau ua kom thoob plaws ntiaj teb.
