Yuav ua li cas LED Teeb Teeb Ua Haujlwm
LED teeb pom kev zoo tuaj. Txij li ntau xyoo dhau los, LEDs tau siv los ua kom pom ntau yam khoom, suav nrog cov moos digital, teeb Christmas, teeb nyem, thiab teeb liab. Tab sis LEDs tsis tau tawm ntawm qhov teeb pom kev hauv tsev. Cov tuam txhab lag luam tsis tuaj yeem tsim lawv li niaj zaus, hloov qhov muag loj vim muaj qee qhov kev txwv. Tab sis, nyob rau hauv kaum xyoo dhau los los yog li ntawd, cov LED hloov qhov muag teev - qhov kev xaiv uas tsuas yog ntsia hlau rau hauv lub teeb zoo li lub teeb incandescent - tau loj hlob nyob rau hauv muaj koob meej. Tam sim no, ib feem loj ntawm cov tsev neeg thiab cov tuam txhab siv lawv.
Raws li kev tshawb fawb xyoo 2017, 38 feem pua ntawm cov neeg Amelikas tau hloov pauv los ntawm cov teeb pom kev zoo rau LED teeb, thaum 70 feem pua ntawm cov neeg Asmeskas tau yuav tsawg kawg ib lub teeb LED. Qhov kev faib ua feem no feem ntau yuav nce tom qab 2017.
Hauv cov ntawv tshaj tawm no, peb yuav tshuaj xyuas seb LED lub teeb qhov muag teev ua haujlwm li cas, vim li cas lawv xaiv lub teeb pom kev zoo, thiab qee qhov txiaj ntsig thiab qhov tsis zoo ntawm kev siv lawv. Cia peb pib nrog cov hauv paus ntsiab lus: Ib qho LED ua teeb pom kev zoo li cas?
Lub hauv paus ntawm LED Lub Teeb Teeb
Ib qho "lub xeev teeb pom kev zoo" thev naus laus zis, lossis SSL, yog qhov LED yog dab tsi. Hauv qhov tseem ceeb, SSL emanates lub teeb los ntawm cov khoom siv uas tsis yog lub tshuab nqus tsev (xws li lub qhov muag teeb) lossis roj (zoo li CFL). Cov khoom no yog semiconductor nyob rau hauv cov ntaub ntawv ntawm ib tug pa LED.
Tsuas yog hais tias, ib qho LED tsim lub teeb thaum muaj hluav taws xob tam sim no ntws los ntawm microchip, illuminating lub teeb me me hu ua LEDs, thiab tsim lub teeb pom kev zoo. Thov xa mus rau Yuav Ua Li Cas Lub Teeb Emitting Diodes Ua Haujlwm kom paub meej meej.
Thaum LEDs tsim ntau lub teeb, ib feem ntawm lub teeb yog daig hauv LEDs cov qauv, uas yog ib qho kev txhawj xeeb thaum siv lawv los ua qhov tseem ceeb ntawm kev teeb pom kev hauv tsev. Yog li ntawd, lub teeb LED feem ntau tau dimmer dua li lub teeb incandescent, thiab cov neeg feem coob nyiam cov teeb ci ntsa iab thiab qab nthab fittings.
LED qhov muag teev yog qhov ci dua. Niaj hnub no, LED hloov qhov muag teev yuav muab qhov ci ci uas tsawg kawg yog sib npaug ntawm 60-watt incandescent teeb, ua rau lawv muaj txiaj ntsig zoo rau cov teeb pom kev hauv tsev. Tsis tas li ntawd, lub neej ntev ntawm LED hloov lub teeb yog 24, 000 teev ntev dua li cov pa roj teeb 60-watt incandescent teeb.
Thiab tus nqi tsawg dua. Koj tuaj yeem txuag tau $ 75 ib xyoos los ntawm kev hloov mus rau LED ENERGY STAR versions rau koj lub tsev tsib lub teeb pom kev zoo tshaj plaws.
Qhov no coj tau qhov zoo thiab qhov tsis zoo ntawm LED qhov muag teev.
Cov txiaj ntsig ntawm LED teeb pom kev zoo
Thawj yog qhov txo qis kev siv zog. Piv nrog rau yav dhau los teeb pom kev yees thev naus laus zis, LED txheej txheem ntawm kev tsim lub teeb siv hluav taws xob tsawg dua rau cua sov. Raws li piv rau CFLs thiab incandescent qhov muag teev, uas tso tawm 90 feem pua ntawm lawv lub zog thaum tshav kub kub, nws muaj zog ntau dua li lub tshuab nqus tsev / filament txoj hauv kev ua haujlwm hauv qhov muag teev. Nws kuj siv tsawg kawg yog 75 feem pua tsawg zog (uas tso tawm txog 80 feem pua ntawm lawv lub zog raws li cua sov).
A 100-watt incandescent teeb yuav siv 432 kilowatt-teev ib xyoos yog tias koj ua haujlwm koj lub teeb pom kev rau 4,320 teev hauv ib xyoos (360 teev hauv ib hlis / 90 teev hauv ib asthiv / 12.85 teev hauv ib hnub), piv rau me ntsis tshaj 60 kilowatt -teev rau qhov sib npaug 14-watt LED teeb. Tsis tas li, LEDs tso tawm 50 feem pua tsawg CO2 dua li CFLs thiab 90 feem pua tsawg CO2 dua li qub halogen qij.
Txawm li cas los xij, qhov no tsuas yog ib feem ntawm cov lus piav qhia. Lwm qhov tseem ceeb yog lub sijhawm ua haujlwm tau zoo: txawm hais tias lub teeb incandescent muaj 1, 000- teev lub neej voj voog, lub teeb pom kev zoo LED muaj lub neej ntev ntawm 25,000 teev lossis ntau dua. Qhov sib txawv ntawm cov teeb pom kev zoo thiab cov teeb pom kev zoo fluorescent thiab cov teeb pom kev zoo hauv lub xeev xws li LEDs yog qhov txaus ntshai: Txhawm rau sib npaug ntawm lub neej ntawm lub teeb ci, lub teeb LED yuav tsum tau tso rau peb xyoos, 24 teev ib hnub, xya hnub hauv ib lub lis piam. (Yuav ua kom ncaj ncees, tsis yog txhua lub teeb LED yuav kav ntev npaum li lawv yuav tsum tau. Yog tias cov khoom tawg sai dhau, qee qhov yuav muaj lub neej luv dua.)
Thaum koj xav txog qhov teeb meem tus nqi, tej yam yuav nyuaj me ntsis vim tias lub sij hawm tau txais txiaj ntsig. Raws li Lub Tsev Depot, plaub-pob ntawm 60-watt LED hloov qhov muag teev nqi ib ncig $9.48 whereas qhov sib npaug plaub-pob ntawm incandescent qhov muag teev nqi $3.97.
Qhov tseeb yog tias LEDs tseem yuav ua kom txuag koj cov nyiaj nyob rau lub sijhawm ntev, txawm tias ntawm $ 9.48 rau ib pob ntawm plaub qhov muag teev, txij li koj tsuas yog xav tau ib lossis ob zaug txhua xyoo los yog li ntawd thiab koj siv tsawg dua rau lub teeb pom kev hauv tsev, uas tuaj yeem nce. mus rau xya lub sij hawm ntau zog npaum li incandescent teeb thiab txo lub zog siv los ntawm ntau tshaj 80 feem pua.
Cov lus nug txog LED Teeb Teeb
LEDs sai sai yuav dominate domestic teeb pom kev zoo. LED teeb los ntawm Philips tuaj nyob rau hauv ntau yam xim-hloov thiab Wi-Fi-txuas qauv. Ntxiv mus, General Electric muaj ib txoj kab ntawm LED ntxiv rau lub teeb uas muaj cov hais lus, timers, hloov xim, thiab lwm yam nta. Los ntawm 2030, nws tau kwv yees tias kev muag khoom LED yuav ua rau 75 feem pua ntawm tag nrho cov teeb pom kev lag luam.
Thaum koj xav txog dab tsi cov kws tshawb fawb tau hais txog LEDs, tej yam tshwm sim tiag tiag mus zoo. Kev tawg yog tshwm sim ntawm qhov ceeb toom. Txawm li cas los xij, muaj ib qho teeb meem.
Kev tshawb fawb ntawm lub teeb xiav uas LEDs tsim tau dhau los ua ntau dua. Peb lub qhov muag thiab kev noj qab haus huv yuav raug mob, raws li cov kws tshawb fawb. Raws li lub koom haum saib xyuas kev noj qab haus huv Fab Kis, nws tuaj yeem hloov kho peb lub moos lom neeg thiab ua rau pw tsaug zog tsis zoo ntxiv rau qhov kev puas tsuaj rau lub qhov muag. Lub koom haum tau qhia kom txwv tsis pub siv cov khoom siv LED nrog rau qib siab tshaj plaws ntawm lub teeb xiav, tshwj xeeb tshaj yog rau cov menyuam yaus. Cov khoos phis tawj, xov tooj ntawm tes, thiab lwm yam khoom siv poob rau hauv pawg no, nrog rau qee yam khoom ua si thiab cov teeb pom kev zoo.
Lub koom haum qhov kev tshawb pom xyoo 2010 hais txog qhov pom ntawm qhov pom ntawm lub teeb xiav, uas tuaj yeem ua rau qhov muag tsis pom kev, tau lees paub hauv 2019 txoj kev tshawb fawb. Lub koom haum Fab Kis rau Khoom Noj, Ib puag ncig thiab Kev Noj Qab Haus Huv & Kev Nyab Xeeb (ANSES) tau hais hauv nws daim ntawv tshaj tawm tias cov tshuaj no "qhia luv luv phototoxic cuam tshuam cuam tshuam nrog kev raug mob hnyav thiab kev cuam tshuam rau lub sijhawm ntev cuam tshuam nrog kev raug mob ntev, uas ua rau muaj kev pheej hmoo loj hlob ntawm lub hnub nyoog. -related macular degeneration (ARMD)".
Siv cov kev sib txuas ntawm nplooj ntawv hauv qab no kom paub ntau ntxiv txog LED teeb pom kev zoo thiab lwm yam kev kawm.
