Qhov zoo thiab qhov tsis zoo ntawm LED qhov muag teev.

Cov txiaj ntsig ntawmLED Teeb Lub Teeb

Thaum pib, muaj qhov txo qis kev siv zog. Daim ntawv LED ntawm illumination siv lub zog tsawg dua rau cua sov piv rau lwm lub teeb pom kev zoo. Nws yog qhov ua tau zoo dua li lub tshuab nqus tsev / filament txoj kev ua haujlwm hauv cov qhov muag teeb, siv tsawg kawg yog 75 feem pua ​​​​tsawg zog thiab tawm cov cua sov tsawg dua piv rau cov qhov muag teev (uas dissipate 90 feem pua ​​​​ntawm lawv lub zog li cua sov) thiab CFLs (uas tso tawm kwv yees li 80 feem pua ​​​​ntawm lawv lub zog raws li cua sov).
Ua haujlwm koj lub teeb pom kev zoo rau 4,320 teev ib xyoos ib zaug (360 teev txhua hli / 90 teev txhua lub lim tiam / 12.85 teev txhua hnub), 100-watt incandescent teeb siv 432 kilowatt-teev toj ib xyoo, whilst piv rau 14-watt LED teeb ib xyoos ib zaug. LEDs tso tawm 90 feem pua ​​​​tsawg CO2 dua li cov qij halogen thiab 50 feem pua ​​​​tsawg dua cov teeb fluorescent (CFLs).
Txawm li cas los xij, kev siv zog ua haujlwm tsuas yog ib feem ntawm cov lus piav qhia. Lwm qhov nam yog kev ua haujlwm ntawm lub sijhawm:High -zoo LED teebTej zaum txoj kev xav yuav kav ntev li 25,000 teev lossis ntau dua, thaum lub teeb incandescent muaj lub neej ntev ntawm 1,000 teev. Cov khoom siv hluav taws xob- lub xeev teeb pom kev zoo, xws li LEDs, muaj kev ruaj ntseg ntau dua li cov teeb pom kev zoo piv rau cov teeb pom kev zoo lossis cov fluorescent, thiab qhov sib txawv yog qhov zoo tshaj plaws: Ib qho yuav tsum siv lub teeb ci LED tsis tu ncua rau 24 teev txhua hnub, xya hnub hauv ib lub lis piam, dhau lub sijhawm ntawm peb xyoos kom sib npaug ntawm lub neej ntawm lub teeb incandescent. Tsis yog txhua lub teeb ci LED ua tiav lawv txoj kev ua neej nyob. Qee cov tib neeg yuav raug txo qis lub neej ntev vim yog qhov tsis zoo thaum ntxov.
Qhov txiaj ntsig ntawm lub cev ua rau nyuaj rau qhov teeb meem nqi. Lub 60-watt LED hloov lub teeb yog tus nqi ntawm ib ncig ntawm $ 9.48 rau plaub-pob, tab sis qhov sib npaug ntawm cov qij taws teeb raug nqi $ 3.97, raws li qhia los ntawm Home Depot.
Hauv kev muaj tiag, txawm tias tus nqi pib ntawm $ 9.48 rau ib pob ntawm plaub qhov muag teev, LEDs thaum kawg tau txais txiaj ntsig nyiaj txiag nyob rau lub sijhawm, vim tias lawv yuav tsum tau hloov ib zaug ib xyoos lossis ob xyoos. Tsis tas li ntawd, lawv muaj rau mus rau xya npaug ntawm lub zog ntau dua -ntau tshaj qhov muag teev, txo lub zog siv ntau dua 80 feem pua.

Kev txhawj xeeb txogLED Lub Teeb Teebs

LEDs tau teeb tsa los tswj lub teeb pom kev hauv tsev. Philips muaj ntau yam ntawm LED teeb nrog cov xim txawv thiab Wi-Fi- qhib qhov muag teev. General Electric muaj ib qho LED + kab nrog lub teeb qhov muag teev nrog cov hais lus, timers, xim hloov kho, thiab ntau yam haujlwm. Nws tau kwv yees tias LEDs yuav suav nrog 75 feem pua ​​​​ntawm tag nrho cov teeb pom kev muag khoom los ntawm 2030.
Raws li cov kws tshaj lij, qhov kev pom ntawm LEDs zoo li qhov zoo. Kev tsim kho tshiab tau tshwm sim ntawm tus nqi nrawm. Txawm li cas los xij, muaj ib qho teeb meem.
Ntau qhov kev tshawb fawb tau tshaj tawm txog lub teeb xiav tawm los ntawm LEDs. Cov kws tshawb fawb tau lees tias nws yuav ua rau muaj kev puas tsuaj rau peb lub qhov muag thiab kev noj qab haus huv tag nrho-. Lub koom haum saib xyuas kev noj qab haus huv Fab Kis tau hais tias nws tuaj yeem ua mob rau lub retina thiab cuam tshuam rau peb cov kab mob circadian thiab kev pw tsaug zog. Lub koom haum tau qhia kom txwv tsis pub siv cov khoom siv LED nrog siab xiav- theem teeb, tshwj xeeb tshaj yog rau cov menyuam yaus. Qhov no suav nrog khoos phis tawj, xov tooj ntawm tes, thiab lwm yam khoom siv, nrog rau tej zaum cov khoom ua si tshwj xeeb thiab teeb pom kev zoo.
Daim ntawv tshaj tawm xyoo 2019 tau txheeb xyuas lub koom haum qhov kev tshawb pom xyoo 2010 txog qhov pom ntawm qhov muag toxicity ntawm lub teeb xiav, uas yuav ua rau tsis pom kev. Fab Kis Lub Chaw Haujlwm Saib Xyuas Khoom Noj, Ib puag ncig thiab Kev Noj Qab Haus Huv & Kev Nyab Xeeb (ANSES) tau hais tias kev kis mob hnyav ua rau luv luv - cov teebmeem phototoxic, thaum raug mob ntev ua rau muaj kev cuam tshuam rau lub hnub nyoog ntev - ntsig txog macular degeneration (ARMD).
