Txheej txheem cej luam
Ib qho ntawm cov kev xaiv zoo tshaj plaws thiab muaj zog tshaj plaws hauv kev lag luam tam sim no yog LED teeb pom kev zoo. Lawv twb yog ib qho kev xaiv teeb pom kev zoo thoob ntiaj teb, thiab lawv qhov kev thov tsuas yog loj tuaj.
Txawm li cas los xij, nws tau siv sijhawm ntau xyoo rau LED teeb pom kev lag luam kom paub tab, thiab tau muaj kev cuam tshuam thiab kev poob siab ntawm txoj kev. Cov evolution ntawm LED teeb-los ntawm lawv lub hauv paus pib me me mus rau cov teeb pom kev zoo niaj hnub no-yuav raug tshuaj xyuas hauv tsab ntawv no.
Thawj Xyoo ntawm LED teeb pom kev zoo
Xyoo 1960s pom qhov kev tsim tawm ntawm lub teeb-emitting diodes (LEDs) los ntawm Nick Holonyak Jr., tus kws ua haujlwm hluas ua haujlwm los ntawm General Electric. Cov teeb ci LED no yog thawj zaug siv los ua cov cim ntawm cov khoom siv hluav taws xob thiab tsuas yog tsim lub teeb siv tsawg heev.
LEDs tsis tau siv rau lub hom phiaj teeb pom kev zoo kom txog thaum xyoo 1970s. Vim lawv qhov qis qis thiab cov nqi tsim khoom siab, cov LEDs thaum ntxov no tsis haum rau kev siv dav dav.
Ua tsaug rau ntau qhov kev tsim kho, LED thev naus laus zis tsis tau pib nce mus txog xyoo 1990. Ci ntsa iab, ua tau zoo dua LEDs tau tsim vim tias kev nce qib hauv kev tsim khoom siv technology, thiab kev tsim cov ntaub ntawv tshiab ua rau nws muaj peev xwm siv LED teeb pom kev zoo hauv kev teeb pom kev thiab teeb pom kev zoo.
Ib qho tseem ceeb tseem ceeb rau kev lag luam teeb pom kev zoo nyob rau hauv thaum ntxov 2000s yog kev tsim thiab kev lag luam ntawm cov tshuab dawb LED. Lub teeb xiav LED tau ua ke nrog cov khoom siv phosphor, uas ib nrab hloov lub teeb xiav rau hauv dawb, los tsim cov LEDs dawb.
Lub zog txuag hluav taws xob LED teeb nrog qhov sov sov, pom cov xim kub tau ua tau los ntawm qhov kev hloov tshiab no, thiab tam sim no lawv tuaj yeem siv rau ntau yam kev siv teeb pom kev zoo.
Kev txhim kho hauv LED Technology
Kev txhim kho hauv kev tsim khoom, thev naus laus zis, thiab kev tshawb fawb tau txhawb nqa kev tsim cov teeb ci LED puas tau txij li cov thev naus laus zis dawb tau tshwm sim thawj zaug.
Txoj kev loj hlob ntawm LED nti yog ib qho tseem ceeb tshaj plaws kev txhim kho hauv LED thev naus laus zis. Kev ua tau zoo ntawm LED teeb tag nrho yog nyob ntawm cov khoom me me no, uas nyob hauv lub teeb-emitting diode.
Kev tsim cov teeb pom kev siab LED nrog cov xim zoo tshaj plaws thiab kev ua neej ntev ntev tau ua tiav los ntawm kev nce qib ntawm cov khoom siv chip zoo dua. Kev ua tau zoo thiab ci ntsa iab ntawm cov teeb pom kev niaj hnub LED kuj tau txhim kho los ntawm kev siv cov khoom zoo tshaj.
Kev nce qib ntawm kev tswj teeb pom kev zoo kuj tau ua lub luag haujlwm tseem ceeb hauv kev txhim kho LED teeb pom kev zoo. Cov teeb pom kev zoo ntse tau ua rau nws muaj peev xwm tswj tau cov teeb pom kev deb ntawm LED, tso cai rau cov neeg siv los kho cov xim kub thiab ci ntsa iab rau lawv nyiam.
Raws li qhov tshwm sim, LED teeb tam sim no tau hloov pauv ntau dua thiab tsim nyog rau ntau yam kev siv teeb pom kev zoo. Tsis tas li ntawd, ntau tus kws tsim vaj tsev thiab cov neeg tsim qauv sab hauv twb tau siv cov teeb ci LED hauv lawv cov haujlwm, ua kom pom tseeb tias lawv tau ua tiav li cas rau hauv kev tsim teeb pom kev zoo.
Qhov zoo ntawm LED teeb pom kev zoo
Cov neeg siv khoom thiab ib puag ncig tau txais txiaj ntsig zoo los ntawm kev nce qib ntawm LED teeb pom kev lag luam thev naus laus zis. Qhov tseem ceeb tshaj, LED teeb siv txog li 85% tsawg zog dua li cov teeb pom kev zoo, ua rau lawv muaj zog heev.
Vim LED teeb lub neej ntev dua thiab qis dua cov nqi siv hluav taws xob, cov neeg siv yuav txuag tau nyiaj ntau ua tsaug rau qhov kev siv hluav taws xob no.
Vim tias cov teeb ci LED tsis muaj cov tshuaj txaus ntshai uas muaj nyob rau hauv cov teeb pom kev zoo, lawv kuj muaj kev nyab xeeb dua. Tsis tas li ntawd, lawv tsim kom muaj cua sov tsawg dua li cov teeb pom kev zoo, uas txo qis qhov muaj hluav taws kub thiab txhim kho kev nyab xeeb hauv tsev.
Qhov kawg tab sis tsis kawg, LED teeb muab lub teeb ci zoo nkauj, zoo nkauj zoo li lub teeb ntuj, txhim kho cov neeg siv kev nplij siab thiab txo qhov muag pom. LED teeb yog lub teeb pom kev zoo tsim nyog rau cov haujlwm muaj tswv yim vim tias lawv muab cov xim kub hloov pauv uas tuaj yeem ua ke los tsim ntau yam xim.
Hauv kev xaus
Cov txheej txheem ntawm kev tsim LED teeb pom kev lag luam thev naus laus zis tau ua haujlwm ntev thiab muaj kev kub ntxhov. LED teeb tau hloov zuj zus los ntawm lawv lub hauv paus pib los ua cov ntsuas hluav taws xob rau cov teeb pom kev zoo, lub zog txuag hluav taws xob.
Kev tsim kho tshiab hauv kev tsim khoom, thev naus laus zis, thiab kev tshawb fawb tau txhawb nqa kev txhim kho ntawm LED teeb pom kev lag luam. Cov nqi txuas ntxiv poob qis vim tias ntau cov tuam txhab tsim kev nqis peev hauv LED thev naus laus zis, thiab kev nce qib hauv cov teeb pom kev zoo no txuas ntxiv thawb nws cov kev txwv.
Vim nws lub neej ntev, kev lag luam hluav taws xob, kev phooj ywg ib puag ncig, thiab kev yoog raws, LED teeb pom kev zoo tau dhau los ua lub teeb pom kev zoo xaiv rau ob lub tsev thiab kev lag luam. Nws yog qhov pom tseeb tias LED teeb pom kev zoo yuav ua lub luag haujlwm tseem ceeb hauv peb lub teeb pom kev yav tom ntej raws li kev xav tau nce thiab kev siv thev naus laus zis.
