Vim li cas LEDs tsis tau txiav lub zog siv rau teeb pom kev zoo

Waterford, Ireland's Altitude Tsheb Kav Khw Eeamon Barrett qhia txog kev caij tsheb kauj vab muag nws. Nyob rau hauv lub ci ntsa iab, cov xim txheej txheem thev naus laus zis, chrome, thiab cov spokes tshiab ci.

Mr Barrett pib tsis nyiam muaj teeb txawb fluorescent nyob rau txhua hnub los txhawb kev thauj khoom ntsuab ntsuab.

Peb xyoos dhau los, nws hloov mus rau Altitude Chav, Rhiav, Cateen, thiab rov qab chaw haujlwm rauLED teeb pom kev zoorau kev ua tau zoo.
Qee chav kawm tam sim no muaj cov lus tsa suab sensors uas qhib teeb pom kev thaum ib tug neeg nkag mus. Ib nrab siv los ntawm niaj hnub hnub ci ntsa iab thiab roj teeb.
"Nws yog ib qho yeej-yeej," Barett. "Qhov zoo ntawm lub teeb pom kev zoo yog qhov zoo dua." Nws lees tias 35% txo qis hauv nws daim nqi hluav taws xob txhua xyoo. Mr. Barrett hais tias txuag yuav tau ntau dua yog tsis muaj Russia qhov kev ntxeem tau ntawm Ukraine, uas skyrocketed zog nqi.
LED teeb pom kev zoo yog lawm kaum xyoo, tab sis ob peb lub lag luam tau ntsia nws. Upfront hloov tus nqi pab txhawb rau qhov ntawd. Mr. Barett Them € 10, {000 (£ 8,800; $ 10,900) ntawm lub teeb tshiab rau nws}}} square-ko taw tsev. Nws xav kom nws yuav tsum muaj xya xyoo los them rov qab no thiab hnub ci ntsa iab thiab cov nqi roj teeb.

Leds ncav cuag lub tsev kawm ntawv xyoo tas los.

Lawv sawv cev 50% ntawm kev tsim teeb ci ntiaj teb kev muag khoom, ib lub koomhaum ua haujlwm thoob ntiaj teb. Txij li ntau tus neeg tau txhim kho hluav taws xob-ua kom pom hluav taws xob zoo dua li tau ua ntej, lub teeb pom kev siv hluav taws xob tau nce. Tseeb LEDs yog ultra-txuag, tsis tau peb yuav tsum tau ua ntau dua kom txo lub teeb pom kev siv hluav taws xob.
"Tus naj npawb ntawm cov teeb siv hauv txhua tsev neeg nce zuj zus," hais tias Imperial College London lub koom haum Shivika mittal. "Uas yog offsetting hloov mus rau coj."
Nws ntseeg ntau lub tsev sab hnub poob tau coj. Cov tsev lag luam lag luam tau siv sijhawm ntev dua los hloov. Tsoomfwv txoj cai yuav txhawb txoj kev hloov pauv. Teeb pom kev zoo nrog cov tshuab ntse zoo li Mr. Barrett cov lus tsa suab Senses txawm muaj lub zog ntau dua, nws hais. Qhov no tuaj yeem txo lub ntiaj teb teeb pom kev zoo siv hluav taws xob.
Phoj cov rooj noj mov yog ua los ntawm cov khoom siv yas los ntawm kev lag luam marmax hauv Nroog Durham. Lub tuam txhab hloov los ntawm Incandescent qij ua rau coj los ua nws lub chaw rau khoom thiab chaw ua haujlwm xyoo tas los. "Peb zoo li peb tau pab vim peb cov khoom lag luam ntau," piav qhia txog tus thawj tswj hwm Dav Dav Dav Dav Johnson. Kev ntsuas kev txo hluav taws xob pom zoo coj LED. "Koj yeej ib txwm ua ntxiv," hais tias Johnson.

Lub teeb hluav taws xob muaj zog yog tias lawv emit lumens ib watt ntawm lub zog.

Paul Sceidt, Cov Neeg Saib Xyuas Khoom Muag Khoom Muag Khoom Hauv Cree LED, hais tias Let nyob rau thaum ntxov 2000. {lumen-per-watt dawb LEDs nyob rau hauv lub Peb Hlis. LEDs siv feem ntau ntawm lawv lub zog los tsim cov photons, thaum incandescent teeb siv 90% thiab cov lumvin dawb ntawm 2,7 lumens ib watt, raws li Mr Scheidt. Txawm li cas los xij, kev txhim kho ntxiv tau kwv yees. Dr. Mittal kwv yees cov teeb tsa no 'efficency yuav nce hauv 20 xyoo.
Hauv qee qhov chaw, kho dua tshiab lub teeb pom kev zoo yog qhov nyuaj. Gemma teeb pom kev zoo rau sab nrauv thiab txoj kev teeb pom kev zoo rau London's Stamford Had Qub xyoo no.

Peb pom 10% ntawm cov teeb tseem ceeb thaum peb tshawb xyuas lub xaib.

Tus Thawj Saib Xyuas Kev Ua Lag Luam Piersenbridge ntseeg ntseeg nws tsim ntau qhov chaw tsaus ntuj. Lub teeb thaum ub yog lub teeb qub tub. Thoob 100 fittings tam sim no tau coj.
Yawg Wottebroge ntseeg cov teeb qub yuav tau noj 341, {{1} Ib xyoo yog tias lawv tau ua haujlwm tau ntau dua 120 qhov nruab nrab British tsev. Lub LEDs tshiab siv 36, 000 kwh xyoo, 90% nyiaj khaws cia.
Tus nqi hloov pauv £ 34,500, tab sis lub teeb pom kev teeb pom kev zoo tias cov qhov muag teev dhau los uas yuav raug nqi £ 115, {} hauv ib xyoos, yog tias lawv txhua tus ua haujlwm.
Lub lag luam tau tshaj tawm ib daim phiaj-dawb hnub ci-lub teeb ci ntsa iab. Nws muaj cov lus tsa suab sensor thiab lub teeb sensor kom tig tau thaum hmo ntuj. Qhov no tsa lub teeb ci ntsa iab ntawm 30% mus rau 100% thaum lub tsheb lossis tib neeg hla.
LEDs emit xiav lub teeb, uas tuaj yeem ua rau kev pw tsaug zog ntxhov thiab kev cuam tshuam. Txawm sov-toned luminaires emit xiav lub teeb. Raws li Dr. Karolina Zielińska-dąbkowska ntawm GDAńSK University of Technology, peb lub qhov muag xiav-rhiab photoreceps.
