Tau ntev, vim tsis muaj qhov tsawg luminous efficiency ntawm LEDs, nws cov kev thov tau raug tsom nyob hauv ntau qhov chaw teeb duab. Nrog rau qhov rov tshwm sim ntawm ultra-high-brightness LEDs (tshwj xeeb tshaj yog dawb LEDs), ntau lub nroog hauv Suav tau nquag siv cov khoom hluav taws xob LED. Ua ntej tshaj, tsoomfwv hais txog kev siv cov teeb ci LED txoj kev teeb, kom tib neeg txuas ntxiv kom pom thiab siv cov khoom hluav taws xob LED teeb. Raws li kev kwv yees los ntawm cov koom haum muaj kev cai thoob ntiaj teb, xyoo pua 21st yuav nkag mus rau lub sijhawm ntawm cov teeb pom kev tshiab tshiab sawv cev los ntawm LED, uas tau hu ua lub cim thib plaub ntawm cov tshiab lub teeb ci.
GG quot; Ntsuab teeb pom kev zoo" yog lub tswvyim tshiab tso rau tom tshav puam txawv teb chaws teeb pom kev zoo nyob rau xyoo 1980s. Qhov kev siv ntawm kuv lub teb chaws' s" ntsuab teeb pom kev zoo" pib xyoo 1996. Cov kauj ruam tseem ceeb kom paub cov phiaj xwm no yog tsim thiab txhawb kev ua haujlwm siab, kev txuag hluav taws xob, txuag teeb pom kev zoo, txo qis ib puag ncig thiab lub teeb pom kev phem, thiab tsim kom muaj qhov zoo, muaj txiaj ntsig, kev lag luam yooj yim, xis, nyab xeeb , txhim khu kev qha, thiab ib puag ncig lub teeb pom kev zoo. Txawm li cas los xij, qhov yuav tsum tau ua rau" teeb pom kev zoo ntsuab" deb dhau los ntawm qhov txaus, thiab nws yog qhov tsim nyog los tsim thiab siv ntau cov txiaj ntsig, txhim khu kev qha, nyab xeeb, thiab lub teeb ci tshiab. Tam sim no, kev siv teeb pom kev siv nyiaj tau kwv yees li 20% ntawm tag nrho cov kev siv hluav taws xob, thiab txo kev siv hluav taws xob ntau yog ib qho tseem ceeb kom txuag tau lub zog. Txhawm rau lub hom phiaj no, kev lag luam tau tshawb nrhiav thiab tsim ntau cov cuab yeej hluav taws xob txuag hluav taws xob thiab ua tiav cov txiaj ntsig. Ntau lub teb chaws txwv kev tsim khoom thiab muag cov teeb txawb uas tsis muaj qhov muag nyob rau hauv cov qauv ntawm cov cai thiab cov cai. Kuv lub teb chaws tseem tau qhia txog cov kev cai coj los tswj kev siv cov khoom siv hluav taws xob ntau thiab cov khoom siv hluav taws xob tsawg, thiab txhawb nqa kev siv hluav taws xob tsawg thiab kev siv hluav taws xob ntau.
Tebchaws Asmeskas, Nyiv thiab lwm lub tebchaws thiab Taiwan ntawm Tuam Tshoj tau kwv yees cov txiaj ntsig ntawm LED teeb pom kev zoo. Hauv Tebchaws Meskas, 55% ntawm lub teeb roj incandescent thiab 55% ntawm lub teeb roj fluorescent tau hloov los ntawm LED, txuag tau li $ 35 txhiab daus las hauv hluav taws xob thiab txo 755 lab tons ntawm cov pa roj carbon dioxide tawm xyoo. Kev hloov pauv ntawm 100% teeb pom kev zoo hauv Nyij Pooj nrog LEDs tuaj yeem txo lub zog hluav taws xob ntawm 1 mus rau 2 lub chaw tsim hluav taws xob nuclear thiab txuag tau ntau dua 1 billion litres cov roj nyoos noj txhua xyoo. Hauv tebchaws Taiwan, 25% ntawm lub teeb hluav taws xob thiab 100% ntawm lub teeb roj hluav taws xob tau hloov los ntawm cov LED dawb, txuag hluav taws xob 11 billion kilowatt-teev hluav taws xob txhua xyoo. Zog txuag hluav taws xob yog lub hauv paus ntsiab lus vim li cas peb xav siv lub teeb ci LED. Tej zaum yuav muaj cov teeb ci LED kim dua li cov teeb pom kev zoo ib txwm, tab sis ib xyoo ntawm kev txuag hluav taws xob tuaj yeem khaws cov peev hauv cov khoom siv hluav taws xob. Rau cov chaw tsim hluav taws xob thiab kev lag luam hluav taws xob, rau mus rau yim lub hlis ntawm kev txuag hluav taws xob tuaj yeem khaws cov peev hauv lub teeb ci. , Yog li ntawd kom tau txais txiaj ntsig lub sijhawm ntawm ntau lub sijhawm ntawm lub zog txuag txhua xyoo los ntawm plaub mus rau cuaj xyoos. Nrog kev kho tshiab ntawm chaw ua haujlwm, cov naj npawb ntawm cov khoos phis tawm hauv peb lub teb chaws txuas ntxiv nce. Ntxiv rau, kuv lub teb chaws LCD TVs siv LED teeb pom kev zoo raws li qhov backlight los ntawm LCD cov ntxaij vab tshaus, uas txuag hluav taws xob ntau. Tam sim no, nrog kev txhim kho ntawm cov txheej txheem tsim ntau lawm ntawm LED, SMD LED cov txheej txheem ntau lawm tuaj yeem ua tiav cov khoom lag luam LED uas hloov cov khoom hluav taws xob ntawm cov tshuaj ntsuam LCD.
