Qhov zoo thiab kev siv ntawm LED teeb pom kev zoo

Niaj hnub no, lub teeb -emitting diode (LED) sawv ua lub zog tshaj plaws -nrhiav thiab ceev- hloov kho teeb pom kev zoo muaj. High- LED qhov muag teev ua tau zoo tshaj lwm yam teeb pom kev zoo hauv ntau txoj hauv kev: lawv khav theeb lub neej ntev dua, muaj zog dua, thiab lub teeb pom kev zoo uas yog piv rau lossis zoo dua rau lwm txoj hauv kev xws li incandescent lossis CFL qhov muag teev.

Kev txuag hluav taws xob tsis sib xws

LED thev naus laus zis yog qhov kev ua si- hloov pauv rau kev siv hluav taws xob, nrog lub peev xwm los hloov kho lub tebchaws United States teeb lub tsev, kev lag luam, thiab cov chaw pej xeem. Rau kev siv nyob hauv tsev, LEDs-tshwj xeeb yog cov uas muaj ntawv pov thawj ENERGY STAR- siv tsawg kawg yog 75% tsawg zog dua li cov teeb pom kev zoo. Dab tsi ntxiv, lawv kav ntev txog 25 lub sij hawm ntev dua, txo cov nqi hluav taws xob thiab cov nqi hloov pauv.

Kev siv dav dav ntawm LEDs tuaj yeem muaj kev cuam tshuam rau kev txuag hluav taws xob hauv lub tebchaws. Cov kev kwv yees hais tias los ntawm 2035, feem ntau cov teeb pom kev zoo nyob thoob plaws Teb Chaws Asmeskas yuav cia siab rau LED thev naus laus zis. Los ntawm xyoo ntawd, kev txuag hluav taws xob txhua xyoo los ntawm LEDs tuaj yeem ncav cuag 569 terawatt- teev (TWh)-ib qho nyiaj sib npaug rau tag nrho cov hluav taws xob txhua xyoo ntawm ntau tshaj 92 lub tshuab hluav taws xob, txhua qhov muaj peev xwm ntawm 1,000 megawatts (MW).

Dab tsi teeb LEDs sib nrug los ntawm lwm yam teeb pom kev zoo?

LEDs sib txawv ntawm cov teeb pom kev zoo thiab cov teeb pom kev sib txuas (CFL) hauv txoj hauv kev tseem ceeb, txhua yam uas ua rau lawv zoo dua:

Lub teeb Source: LEDs yog me me - txog qhov loj ntawm cov kua txob fleck - thiab tuaj yeem tsim lub teeb nyob rau hauv ntau yam xim. Txhawm rau tsim lub teeb dawb, cov tuam txhab lag luam feem ntau muab cov xim liab, ntsuab, thiab xiav LEDs.

Kev taw qhia: Tsis zoo li incandescent los yog CFL qhov muag teev, uas emit lub teeb nyob rau hauv tag nrho cov lus qhia, LEDs cam khwb cia lub teeb nyob rau hauv ib tug tshwj xeeb kev taw qhia. Qhov no tshem tawm qhov xav tau ntawm cov reflectors lossis diffusers (uas tuaj yeem teeb lub teeb) thiab ua rau cov LEDs muaj txiaj ntsig zoo rau kev siv xws li recessed downlights lossis ua haujlwm teeb pom kev zoo. Rau lwm hom teeb pom kev zoo, ntau lub teeb (feem ntau dhau ib nrab) ploj vim nws yuav tsum tau cuam tshuam rau thaj chaw uas xav tau, tsis txhob tawm ntawm qhov chaw.

Thaum tshav kub kub Emission: LEDs nyob txias, tso cua sov me ntsis. Hauv qhov sib piv, cov qhov muag teeb hluav taws xob pov tseg 90% ntawm lawv lub zog raws li cua sov, thaum CFLs tso tawm ib ncig ntawm 80% ntawm lawv lub zog raws li cua sov- ua rau LEDs muaj kev nyab xeeb thiab ua haujlwm zoo dua.

Kev ua neej nyob: LED cov khoom muaj lub neej ntev heev. Lub siab- zoo LED teeb tuaj yeem kav ntev li 3-5 npaug ntawm CFL thiab tag nrho 30 npaug ntev dua li lub teeb pom kev zoo, txo kev txij nkawm thiab hloov tsis yooj yim.

Common LED Khoom rau Tsev thiab Kev Lag Luam

LED teeb pom kev zoo yog muaj nyob rau hauv ib tug loj thiab loj hlob ntau yam ntawm cov khoom rau ob qho tib si nyob rau hauv thiab industrial siv. Ua tsaug rau kev nce qib thev naus laus zis sai, LEDs tam sim no nkag tau yooj yim dua, tsim tau zoo dua, thiab pheej yig dua li qub. Hauv qab no yog qee cov khoom siv dav siv LED:

Kev lag luam thiab kev lag luam teeb pom kev zoo

LEDs 'kev ua haujlwm siab thiab kev taw qhia lub teeb ua rau lawv zoo tagnrho rau kev lag luam thiab chaw lag luam. Lawv feem ntau siv rau hauv:

Txoj kev teeb thiab chaw nres tsheb teeb pom kev zoo

Txoj kev taug kev thiab sab nraum zoov teeb pom kev zoo

Cov teeb pom kev hauv tub yees (rau cov khw muag khoom noj thiab cov tsev khaws khoom)

Modular teeb pom kev zoo systems

Teeb pom kev ua haujlwm rau cov chaw ua haujlwm thiab chaw ua haujlwm

Hauv qab -Cabinet Teeb pom kev zoo

LEDs 'me me thiab tsom teeb pom kev zoo ua rau lawv zoo tshaj plaws rau kev teeb pom kev zoo, xws li chav ua noj countertops -zoo tagnrho rau kev ua noj lossis nyeem zaub mov. Txij li thaum LED nyob rau hauv - txee teeb tuaj yeem sib txawv ntawm cov xim thiab cov kev taw qhia, nws yog ib qho tseem ceeb rau kev sib piv cov khoom kom pom qhov zoo tshaj plaws haum rau koj qhov chaw tshwj xeeb.

Recessed Downlights

Recessed downlights yog ib qho tseem ceeb hauv tsev thiab kev lag luam. Lawv feem ntau siv hauv chav ua noj hauv tsev, hauv tsev, thiab chav dej, nrog rau hauv chaw ua haujlwm thiab cov tsev lag luam. Raws li US Department of Energy (DOE), muaj ntau dua 600 lab recessed downlights ntsia nyob rau hauv Teb Chaws Asmeskas cov tsev thiab cov lag luam-ntau qhov tam sim no tau hloov kho rau LEDs kom ua tau zoo dua.

LED Hloov Qhov muag teev

Raws li LED kev ua tau zoo txhim kho thiab cov nqi poob qis, LED teeb tau dhau los ua tus nqi - siv tau zoo rau cov qij taws. Lawv tuaj yeem hloov tau yooj yim 40W, 60W, 75W, thiab txawm tias 100W incandescent qhov muag teev. Txhawm rau xyuas kom koj xaiv lub teeb pom kev zoo, nco ntsoov xyuas Lub Teeb Pom Kev Pom Zoo: nws muab cov ntsiab lus tseem ceeb xws li ci ntsa iab (hauv lumens) thiab xim kub, pab koj phim lub teeb rau nws txoj kev siv (xws li chav pw thiab chav ua noj).

LED hnub so teeb

LEDs kuj yog ib qho kev xaiv nrov rau cov teeb pom kev zoo nkauj hnub so (xws li Christmas ntoo teeb), vim lawv siv hluav taws xob tsawg dua li cov hlua hnub so. Tshaj li kev txuag hluav taws xob, LED hnub so teeb muaj cov txiaj ntsig ntxiv:

Muaj kev nyab xeeb dua: Lawv nyob twj ywm txias dua li cov teeb pom kev zoo, txo qhov kev pheej hmoo ntawm hluav taws kub lossis ntiv tes kub.

Sturdier: Ua los ntawm epoxy lo ntsiab muag (tsis yog iav), lawv muaj peev xwm tiv taus kev tawg.

Ntev dua -Ntev: Ib txheej ntawm LED hnub so teeb tseem tuaj yeem siv 40 lub caij so hnub so txij tam sim no.

Yooj yim rau nruab: Koj tuaj yeem txuas mus txog 25 LED txoj hlua kawg - mus rau - kawg yam tsis muaj overloading lub qhov (socket) phab ntsa - deb tshaj li cov hlua incandescent.
