Dab tsi yog Led Lights Stand Rau?

LED teeb, uas sawv cev rau Lub Teeb Emitting Diodes, tau dhau los ua neeg nyiam nyob rau xyoo tas los no vim lawv lub zog ua haujlwm, lub neej ntev, thiab ntau yam. Txawm hais tias koj paub txog cov teeb ci LED lossis tsuas yog pib kawm txog lawv, nws yog ib qho tseem ceeb kom nkag siab tias lub teeb LED sawv ntsug li cas thiab lawv yuav pab tau koj li cas. Hauv tsab xov xwm no, peb yuav tshawb txog ntau yam ntawm LED teeb, suav nrog lawv keeb kwm, thev naus laus zis, kev siv, thiab qhov zoo. Thaum kawg ntawm tsab xov xwm no, koj yuav muaj kev nkag siab zoo ntawm LED teeb thiab lawv qhov tseem ceeb hauv ntiaj teb niaj hnub no.

Cov cim keeb kwm ntawm LED teeb

Keeb kwm ntawm LED teeb hnub rov qab mus rau thaum ntxov xyoo pua 20th thaum cov kws tshawb fawb pom qhov tshwm sim ntawm electroluminescence nyob rau hauv tej yam khoom semiconductor. Txawm li cas los xij, nws tsis yog txog thaum xyoo 1960 uas cov teeb pom kev zoo LED tau tsim. Thawj lub tswv yim LED tau tsim los ntawm Nick Holonyak Jr. hauv xyoo 1962 thaum ua haujlwm rau General Electric. Lub LED thaum ntxov no tau tso tawm lub teeb liab qis, tab sis nws tau tsim lub hauv paus rau kev txhim kho cov teeb pom kev zoo ntawm LED ntau xyoo tom ntej.

Ob peb xyoos tom ntej no, cov kws tshawb fawb thiab cov kws tsim qauv tau ua qhov kev nce qib tseem ceeb hauv LED thev naus laus zis, ua rau muaj kev txhim kho ntawm LED teeb hauv ntau xim thiab siv zog. Nyob rau xyoo 1990, xiav LEDs tau ua tiav tiav, uas ua rau cov khoom siv hluav taws xob dawb. Niaj hnub no, LED teeb muaj nyob rau hauv ntau yam xim thiab siv nyob rau hauv suav tsis txheeb daim ntaub ntawv, los ntawm cov teeb pom kev zoo nyob rau hauv hluav taws xob.

Symbols Technology Tom qab LED Teeb

Cov thev naus laus zis tom qab LED teeb yog ua raws li lub hauv paus ntsiab lus ntawm electroluminescence, uas yog cov txheej txheem ntawm emitting lub teeb raws li qhov tshwm sim ntawm cov hluav taws xob tam sim no dhau los ntawm cov khoom siv semiconductor. LED teeb muaj xws li ib tug semiconductor diode uas emits lub teeb thaum ib tug hluav taws xob tam sim no hla nws. Cov khoom siv semiconductor feem ntau siv hauv LED teeb yog gallium arsenide, gallium phosphide, thiab gallium nitride.

LED teeb tau paub txog lawv lub zog ua haujlwm, vim lawv hloov cov feem pua ​​​​ntawm cov hluav taws xob ntau dua rau hauv lub teeb piv rau cov teeb pom kev zoo lossis cov teeb fluorescent. Qhov no yog ua tiav los ntawm kev siv "bandgap" hauv cov khoom siv semiconductor, uas tso cai rau kev hloov pauv ntawm lub zog mus rau lub teeb. Tsis tas li ntawd, LED teeb muaj lub neej ntev dua li cov teeb ci ib txwm muaj, nrog qee qhov LEDs kav ntev txog 50,000 teev lossis ntau dua.

Cov cim siv cov teeb ci LED

LED teeb yog siv nyob rau hauv ntau yam kev siv, los ntawm tsev neeg teeb pom kev zoo mus rau kev lag luam thiab kev lag luam lub hom phiaj. Hauv cov chaw nyob, LED teeb feem ntau yog siv rau kev teeb pom kev dav dav, teeb pom kev ua haujlwm, thiab teeb pom kev zoo nkauj. Lawv lub zog ua haujlwm tau zoo thiab lub neej ntev ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev txo qis kev siv hluav taws xob thiab kev saib xyuas cov nqi. LED teeb kuj tseem siv rau hauv cov khoom siv hluav taws xob, xws li cov moos digital, teeb pom kev, thiab cov paib sab nraum zoov, vim lawv qhov ci thiab pom kev.

Hauv kev lag luam thiab kev lag luam, LED teeb yog siv rau ntau lub hom phiaj, nrog rau cov teeb pom kev hauv tsev, teeb pom kev zoo, thiab teeb pom kev zoo. LED teeb kuj tseem siv dav hauv kev siv tsheb thiab tsheb thauj mus los, xws li lub teeb taub hau, nres teeb, thiab teeb pom kev sab hauv. Lub versatility thiab durability ntawm LED teeb ua rau lawv haum rau ntau yam kev siv sab hauv tsev thiab sab nraum zoov.

Cov cim zoo ntawm LED teeb

Muaj ntau qhov zoo ntawm kev siv cov teeb ci LED piv rau cov khoom siv teeb pom kev zoo. Ib qho ntawm cov txiaj ntsig tseem ceeb yog lawv lub zog siv hluav taws xob, vim tias cov teeb ci LED siv lub zog tsawg dua thiab tsim lub teeb ntau dua, ua rau cov nqi hluav taws xob qis dua thiab txo qhov cuam tshuam ib puag ncig. LED teeb kuj tseem muaj lub neej ntev dua, uas txhais tau tias tsis tshua muaj kev hloov pauv thiab cov nqi kho qis dua.

Lwm qhov kom zoo dua ntawm LED teeb yog lawv cov versatility ntawm cov xim thiab siv. LED teeb tuaj yeem tsim ntau yam xim, ua rau lawv haum rau ntau yam teeb pom kev zoo thiab kev siv. Tsis tas li ntawd, LED teeb yog instant-on thiab tsis tas yuav tsum tau sov so lub sij hawm, tsis zoo li tej tsoos teeb. Qhov no ua rau lawv zoo tagnrho rau cov ntawv thov uas tsim nyog rau cov teeb pom kev zoo tam sim ntawd, xws li teeb pom kev kub ntxhov thiab teeb pom kev zoo.

Cov cim yav tom ntej ntawm LED teeb

Lub neej yav tom ntej ntawm LED teeb zoo li kev cog lus, nrog kev tshawb fawb thiab kev txhim kho txuas ntxiv tsom mus rau kev txhim kho lawv cov kev ua tau zoo, lub neej ntev, thiab ntau yam. Cov kws tshawb fawb tau ua haujlwm los tsim cov khoom siv semiconductor zoo dua thiab cov txheej txheem tsim khoom kom txo tau cov nqi ntawm LED teeb thiab ua rau lawv nkag tau yooj yim rau cov neeg siv khoom.

Kuj tseem muaj kev txaus siab ntxiv rau kev siv cov teeb pom kev zoo uas siv cov thev naus laus zis LED los muab cov kev daws teeb meem teeb pom kev zoo thiab lub zog txuag hluav taws xob. Cov teeb pom kev zoo no tuaj yeem tswj tau los ntawm kev siv lub xov tooj smartphones lossis lwm yam khoom siv, tso cai rau cov neeg siv kho qhov ci, xim, thiab teem caij raws li lawv nyiam.
