Yuav ua li cas lub zog efficiency thiab ntev - lub sij hawm txuag nqi ntawm LED pob kws teeb piv rau cov pa kev xaiv teeb pom kev zoo? - Kev Paub

Raws li cov teeb pom kev zoo dhau los ua lub zog ntau dua - ua haujlwm tau zoo, LED thev naus laus zis tau tshwm sim los ua cov cuab yeej tseem ceeb rau kev txiav cov nqi thiab kev puas tsuaj ib puag ncig. Lub teeb pob kws, yog li hu ua vim lawv cov pob kws cob- zoo li cov duab thiab LEDs nyob ib puag ncig lub cylindrical core, yog ntawm cov kev tsim kho tshiab ntawm LED uas tau dhau los ua qhov tseem ceeb rau ob qho loj - nplai thiab retrofit teeb pom kev zoo. Txawm li cas los xij, yuav ua li cas lawv lub sij hawm ntev - txuag nyiaj thiab txuag hluav taws xob tiv thaiv ntau qhov kev xaiv xws li siab - siv hluav taws xob tawm (HID), fluorescent, thiab incandescent teeb?

Kab lus no tshuaj xyuas cov txiaj ntsig kev ua haujlwm thiab kev lag luam ntawmLED pob kws teeb, muab kev sib piv zoo nrog cov kab ke ib txwm muaj thiab piav qhia cov laj thawj rau lawv qhov kev nyiam ntawm cov tsev neeg, cov tuam txhab, thiab cov nroog loj.
Tsom teeb pom kev zoo yees: Cov kev txwv tseem ceeb

Peb thawj zaug saib qhov tsis zoo ntawm cov teeb pom kev zoo ib txwm siv kom nkag siab txog qhov zoo tshaj ntawm LED pob kws teeb:

Kev siv hluav taws xob tsawg heev, hloov pauv tsuas yog 10 mus rau 15 lumens ib watt (lm / W).

Lifespan: 1,000 teev nyob rau nruab nrab; luv luv.

Cons: Lawv kim thiab tsis ruaj khov rau ib puag ncig vim tias 90% ntawm lub zog poob raws li cua sov.

Kev siv hluav taws xob nruab nrab, tsim tawm 50-70 lm / W.

Lifespan: 8,000-15,000 xuab moos, ntev tshaj li lub teeb.

Cons: Tsim lub teeb tsis sib xws, raug kev txom nyem thaum huab cua txias, thiab muaj cov mercury txaus ntshai.

Nyob ntawm seb hom, kev siv hluav taws xob muaj peev xwm ntawm 50 txog 120 lm / W.

10,000-24,000 teev yog lub neej ntev.

Cons: Siv sijhawm ntev los ua kom sov, muaj lub lumen loj heev, thiab ua kom sov ntau.

Txawm hais tias lawv tseem siv dav hauv cov khoom siv qub, cov tshuab ua haujlwm muaj ntau qhov tsis zoo, suav nrog kev siv hluav taws xob ntau, kev saib xyuas tsis tu ncua, thiab kev phom sij ib puag ncig.
Zog Efficiency: Sib piv LED thiab Pa Pob Kws Teeb

Hauv peb qhov tseem ceeb, LED pob kws teeb ua tau zoo dua li cov teeb pom kev zoo:

LED pob kws teeb muaj txiaj ntsig zoo dua li kev xaiv ib txwm muaj, ua tiav 80 txog 150 lm / W. Piv txwv li:

Txog 1,500 lumens (15 lm / W) yog tsim los ntawm 100W incandescent teeb.

Txog 12,000 lumens (80 lm / W) yog tsim los ntawm 150W hlau halide HID teeb.

Lub 12,000 lumens ntawm HID yog sib tw los ntawm 50W LED pob kws teeb ntawm 240 lm / W, uas siv 66% tsawg zog.

Tsis zoo li cov LEDs ib txwm muaj (uas tsim cov teeb pom kev zoo), pob kws teeb pom kev sib cais ntawm photons nyob rau hauv 360 degrees, replicating lub spherical tso zis ntawm HID los yog incandescent teeb. Qhov no tshem tawm qhov xav tau ntawm cov reflectors lossis ob peb lub teeb los tsim cov kev pabcuam dav dav, txuag kev siv hluav taws xob.

Cov teeb tsoos tsoos deteriorate sai. Hlau halide teeb, piv txwv li, poob ib nrab ntawm lawv cov ci ntsa iab nrog lub sijhawm. Ntev- lub sij hawm ua tau zoo yog ua kom ntseeg tau nrog LED pob kws teeb, uas tswj tau ntau dua 90% ntawm lawv lub zog qub txawm tias tom qab 50,000 teev.
Ntev -Cov Nqi Them Nqi Them Ntev: Kev Ntsuas Kev Ntsuas

LED pob kws teeb yog kim dua pib, tab sis lawv them sai sai rau lawv tus kheej ntawm kev ua haujlwm txuag nyiaj. Cia peb saib ib qho piv txwv:
Case Study: Warehouse Retrofit

100 hlau halide teeb (400W ib thooj) ua rau kev teeb tsa tam sim no.

Lub Sijhawm Ua Haujlwm: 4,000 teev hauv ib xyoos.

Tus nqi hluav taws xob yog $ 0.12 ib kWh.

Tus nqi ntawm Hlau Halide:

Kev Siv Hluav Taws Xob: Rau 100 qhov sib dhos, txhua qhov 400W fixture siv 160,000 kWh ib xyoos, uas tuaj txog $ 19,200 txhua xyoo.

Lifespan: 15,000 teev, yuav tsum tau 1.3 hloov ib fixture tshaj tsib xyoos.

Kev Kho: Tus nqi nruab nrab txhua xyoo rau kev hloov pauv ntau zaus yog $5,200.

Kev siv hluav taws xob: Siv 150WLED pob kws teebhloov 400W HID txo qis kev siv hluav taws xob txhua xyoo rau 60,000 kWh, uas tuaj txog $ 7,200 txhua xyoo.

Lub neej ntev: 50,000 teev, tshem tawm qhov xav tau kev hloov pauv rau ntau tshaj tsib xyoos.

Kev Kho: Tsis muaj nqi zog rau kev hloov.

Tsib-Xyoo Txuag:

Kev txuag hluav taws xob: $ 60,000. ($19,200 - $7,200) x 5.

Kev Them Nyiaj: $5,200 x 5=$26,000.

$86,000 nyob rau hauv tag nrho cov nyiaj khaws tseg (tsawg dua pib cov nuj nqis LED).

Lub Sijhawm Them Rov Qab: Piv txwv tias txhua lub teeb pob kws LED raug nqi $ 100, tsis zoo li hlau halide $ 40.

Tus nqi hloov tshiab yog $6,000 (100 fixtures x $100 - $40).

$6,000 ÷ ($86,000 ÷ 5) ≈ 4 lub hlis yog lub sijhawm them rov qab.

Txo cov nqi cua txias
HVAC cov tshuab yuav tsum tau ua haujlwm hnyav dua vim tias cov roj teeb thiab HID teeb ua kom sov ntau dhau. Nyob rau hauv ib puag ncig, LED pob kws teeb txuag cua txias siv los ntawm 10-20% txij li thaum lawv khiav txias.

Kev hloov kho dua tshiab rau LEDs feem ntau tau txais kev pab los ntawm kev siv hluav taws xob thiab tsoomfwv. Piv txwv li, kev teeb tsa tau lees paub tuaj yeem tau txais kev pab nyiaj los ntawm US ENERGY STAR program.

Zoo dua LED teeb pom kev zoo (zoo dua CRI, piv txwv li) txo qhov yuam kev thiab qhov muag pom. Kev tshawb fawb qhia tias kev ua haujlwm hauv chaw ua haujlwm tuaj yeem nce 15% thaum lub teeb pom kev zoo.

Txo cov pa roj carbon emissions: Siv ib qhoLED pob kws teebhloov ntawm 400W HID teeb txo CO2 emissions li ntawm 1,500 phaus ib xyoos.

Mercury-Dawb: LEDs yooj yim dua pov tseg vim tias lawv tsis muaj cov khoom phom sij xws li fluorescents thiab HIDs ua.

Recyclability: 95% ntawm pob kws lub teeb tsim los ntawm txhuas tuaj yeem rov ua dua.

Hwm LED pob kws teeb muaj nyob rau hauv nqe ntawm $ 50 txog $ 150, tab sis cov nqi them ua ntej raug txo los ntawm kev xaiv qiv, rov qab, thiab kev yuav khoom ntau.

Kev tshem tawm ballast yog tsim nyog rau LED retrofits ntawm qee qhov HID fixtures. Xaiv rau "ballast-tshaj" qauv los pab txhim kho.

Cov dab dej kub kub tseem tsim nyog rau siab -cov teeb pom kev zoo txawm tias LEDs ua haujlwm zoo dua. Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws, xyuas kom cov khoom siv muaj qhov cua txaus.

Txoj Kev Teeb Pom Kev Tom Qab hloov 140,000 txoj kev teeb rau LEDs, cov nroog xws li Los Angeles tuaj yeem txuag tau $ 9 lab txhua xyoo.

High-bay pob kws teeb muab teeb pom kev ntsug rau cov racks thaum siv 50-70% tsawg zog.

Cov khw
Lub teeb pob kws nrog CRI siab (90+) nce cov khoom pom thiab tuaj yeem nce muag.

Kev sib koom ua ke ntse: Kev siv hluav taws xob raug txo los ntawm 30% thaum lub teeb pobkws tau nruab nrog lub suab sensors lossis nruab hnub ci.

Circular Economy: Leasing qauv (piv txwv li, "teeb pom kev zoo-raws li-a- kev pabcuam") tshem tawm cov nqi them ua ntej tag nrho.

LED pob kws teebtsis yog tsuas yog kev hloov kho tshiab xwb -lawv sawv cev rau kev xav tau nyiaj txiag thiab ib puag ncig. Los ntawm kev txo qis kev siv hluav taws xob los ntawm 50-80%, zam kev hloov pauv tsis tu ncua, thiab txo cov nuj nqis ntxiv (piv txwv li, cua txias, txij nkawm), lawv ua tau zoo dua cov teeb pom kev zoo ntawm txhua qhov kev ntsuas. Thaum qhov kev siv nyiaj thawj zaug tuaj yeem tshwm sim ntau dhau, ROI yog qhov tseeb, nrog lub sijhawm them rov qab feem ntau hauv ib xyoos hauv siab -siv cov xwm txheej.

Rau cov tuam txhab, cov nroog, thiab cov tsev xav kom txo cov nuj nqis thiab cov pa roj carbon hneev taw, LED pob kws teeb muab rau yav tom ntej - pov thawj lwm yam. Raws li thev naus laus zis nce qib thiab cov nqi txo qis, lawv txoj kev tswj hwm hauv kev teeb pom kev zoo tsuas yog nthuav dav, qhia tias kev ruaj khov thiab kev txuag nyiaj tsis yog qhov sib txawv.
