Dab tsi yog qhov zoo dua, LED lossis incandescent?
Kev soj ntsuam ntxaws ntxaws ntawm kev ua tau zoo, kev siv hluav taws xob, tus nqi -kev ua tau zoo, kev cuam tshuam ib puag ncig, thiab kev ua tau zoo nyob thoob plaws-cov ntawv thov hauv ntiaj teb yog qhov tsim nyog los txiav txim siab seb LED (Lub Teeb-Emitting Diode) lossis lub teeb pom kev zoo dua. Thomas Edison tau tsim lub teeb pom kev zoo nyob rau hauv lub xyoo pua puv 19, thiab ntau tshaj li ib puas xyoo, lawv tau tswj cov teeb pom kev lag luam ua tsaug rau lawv cov qauv ncaj nraim tab sis tsis muaj txiaj ntsig. Ntawm qhov tod tes, LEDs, kev tsim kho thev naus laus zis ntawm nees nkaum-ib xyoo pua, tau daws yuav luag tag nrho cov teeb meem ntawm cov teeb pom kev zoo, hloov txoj hauv kev uas peb teeb peb lub tsev, chaw ua haujlwm, thiab thaj chaw pej xeem. Ib sab -los ntawm- sab piv qhia tiasLEDsyog qhov kev xaiv zoo dua rau feem ntau ntawm cov teeb pom kev zoo tam sim no, txawm tias cov qij taws tseem muaj qhov me me ntawm cov nqi hauv qee qhov xwm txheej.
Efficiency ntawm Zog: LEDs muab kev ua haujlwm tsis zoo
Kev siv hluav taws xob zoo yog qhov sib txawv ntawm LEDs thiab cov qij incandescent, thiab nws muaj qhov cuam tshuam ncaj qha rau cov phiaj xwm kev siv nyiaj hauv tsev nrog rau cov phiaj xwm kev txhawb nqa thoob ntiaj teb. Txhawm rau kom cov qhov muag tsis pom kev ci ntsa iab thiab tsim lub teeb, cov hluav taws xob tam sim no yuav tsum tau dhau los ntawm nyias tungsten filament, cua sov rau qhov kub siab heev (kwv yees li 2,700 degree). Tsuas yog 5-10% ntawm lub zog siv tau hloov pauv mus rau qhov pom kev pom, thiab lwm qhov 90-95% yog squandered raws li cov cua sov, ua rau cov txheej txheem no intrinsically inefficient. Ib qho piv txwv yuav yog lub teeb pom kev zoo 60-watt incandescent teeb, uas yog ib zaug muaj nyob rau hauv chav pw thiab chav nyob, tab sis tsuas yog xa 800-900 lumens (lub tsev ib txwm ntsuas lub teeb tsim) thaum siv 60 watts ntawm hluav taws xob txhua teev. Ntxiv nrog rau kev nce nqi hluav taws xob, qhov kev ua tsis tau zoo no ua rau muaj kev nyuaj siab ntau ntxiv rau cov khoom siv hluav taws xob.
Nyob rau hauv sib piv, LEDs tsim lub teeb los ntawm ib tug txheej txheem hu ua electroluminescence, nyob rau hauv uas ib tug hluav taws xob tam sim no ntws los ntawm ib tug semiconductor ua rau photons tso tawm. Txij li thaum tsis tshua muaj hluav taws kub pov tseg nrog cov txheej txheem no, 75-90% ntawm lub zog siv los ntawm LEDs tau hloov mus rau qhov pom kev pom. Lub teeb LED siv tsuas yog 8-12 watts ntawm hluav taws xob los tsim tib yam 800-900 lumens raws li 60-watt incandescent noob, uas yog 70-80% txo ntawm kev siv zog. US Department of Energy (DOE) tshaj tawm tias ib tsev neeg tuaj yeem txuag tau ntawm tsib caug thiab ib puas duas las hauv ib xyoos ntawm kev siv hluav taws xob los ntawm kev hloov kaum lub qhov muag teev nrog LEDs. Loj-scale LED saws txo qis cov pa hluav taws xob hauv tsev cog khoom thiab pab ua kom tiav cov hom phiaj kev nyab xeeb thoob ntiaj teb los ntawm kev txo qhov kev thov rau fossil fuel-powered fais fab nroj tsuag.
Lifespan: LEDs dhau kaum xyoo ntev dua li cov teeb ci
Lwm qhov chaw tseem ceeb uas LEDs ua tau zoo dua li qhov muag teev yog lub neej, uas txo cov khoom pov tseg thiab kev saib xyuas. Incandescent qhov muag teev 'rhiab heev tungsten filament deteriorates lub sij hawm vim yog tas li cua sov thiab txias (los ntawm kev qhib thiab tua), uas nquag ua rau burnout. Nrog rau 1,000-2,000 teev lifespan, ib lub teeb incandescent tsuas yog siv tau rau 1-2 xyoos ua ntej yuav tsum tau hloov yog siv peb teev ib hnub twg. Cov neeg siv tau npau taws los ntawm qhov kev hloov pauv tsis tu ncua, uas tseem ntxiv rau cov khoom pov tseg los ntawm kev ua kom muaj cov khoom pov tseg hauv qhov chaw pov tseg.
LEDsmuaj lub neej ntev kawg nkaus vim tias lawv tsis muaj filaments tsis muaj zog. Nrog peb teev ntawm kev siv txhua hnub, feem ntau ntawm siab - LEDs zoo nyob ntawm 50,000 thiab 100,000 teev. Rau qhov muag teev uas siv tsawg zaus (xws li hauv cov txee dai khaub ncaws lossis chaw nres tsheb), qhov no sib npaug txog li 20 xyoo ntawm kev ua haujlwm tau zoo. Raws li DOE, kev lag luam - qib LEDs uas tau npaj rau kev siv nquag hauv cov tsev khaws khoom lossis chaw ua haujlwm tuaj yeem siv sijhawm ntev txog 100,000 teev. Qhov kev ua haujlwm ntev no txhais tau hais tias thoob plaws hauv nws lub neej, ib lub teeb ci LED tuaj yeem hloov 25-50 qhov muag teev, tshem tawm qhov xav tau rov qab mus ncig kom tau txais kev hloov pauv lossis kev pheej hmoo ntawm kev nce qib los hloov cov qij uas nyuaj rau ncav cuag. Qhov no txhais tau tias txo qis qis qis thiab txo tus nqi kho rau kev lag luam, thiab yooj yim dua thiab kev thaj yeeb nyab xeeb rau tsev neeg.
Tus nqi: Txawm tias lawv cov nqi pib siab dua, LEDs muab sijhawm ntev - txuag nyiaj.
Thaum xub thawj siab ib muag, qhov muag teev incandescent zoo li pheej yig dua: qhov sib npaug ntawm LED teeb nqi ntawm \\(2.00-\\)5.00, tab sis qhov yooj yim 60-watt incandescent teeb feem ntau raug nqi \\(0.50-\\)1.00. Thaum cov nqi hluav taws xob thiab hloov zaus raug coj mus rau hauv tus account, LEDs muab kev txuag nyiaj ntev dua, yog li qhov sib txawv ntawm tus nqi pib yog dag.
Qhov no tau pom meej meej los ntawm ib sab -los ntawm- sab suav tus nqi tshaj 50,000 teev, uas yog qhov nruab nrab lub neej ntawm ib qhoLED teeb.
Xav tias tus nqi ntawm lub hwj chim yog $ 0.15 ib kWh:
Ib lub teeb ci incandescent Txij li txhua qhov teeb pom kev zoo siv sijhawm 2,000 teev, 25 yuav tsum ncav cuag 50,000 teev. Qhov muag teev yuav raug nqi 25 x \\(1.00=\\) 25.00. (60 watts / 1,000) x 50,000 teev x \\(0.15/kWh=\\)450.00 yog tus nqi zog. Tus nqi tag nrho lub neej yog $475.00 (\\({19}} \\)450).
LED Noob: Ib lub teeb LED nrog 50,000-teev lifespan yog txhua yam uas xav tau. Tus nqi ntawm lub teeb yog \\(5.00). (8 watts / 1,000) x 50,000 teev x \\)0.15/kWh=\\(60.00) yog tus nqi zog. Tus nqi tag nrho ntawm kev ua tswv yog \\)5 + \\(60)=\\)65.00.
Nyob rau hauv cov ntaub ntawv no, lub teeb LED txuag $ 410 thaum lub sij hawm nws lub neej, uas yog ntau tshaj xya npaug ntawm nws thawj tus nqi. Cov nyiaj khaws cia no tuaj yeem ntxiv rau cov tsev loj, khw muag khoom, lossis cov tsev khaws khoom nrog ntau lub teeb pom kev zoo. Tsis tas li ntawd, cov nqi tau poob ntau dua 80% txij li xyoo 2010 los ntawm kev nthuav dav thoob ntiaj teb ntawm LED tsim khoom, ua rau lawv pheej yig dua li qhov muag teeb.
Kev cuam tshuam rau ib puag ncig: LEDs muaj ntau yam ruaj khov
Niaj hnub nimno teeb pom kev zoo yuav tsum coj mus rau hauv tus account sustainability, thiabLEDsexcel nyob rau hauv cheeb tsam no ib zaug ntxiv piv rau incandescent qhov muag teev. Kev siv hluav taws xob siab thiab kev pov tseg tsis tu ncua yog ob txoj hauv kev tseem ceeb uas cov teeb ci incandescent puas rau ib puag ncig. Raws li tau hais yav dhau los, lawv qhov tsis muaj peev xwm nce qhov xav tau ntawm lub zog, uas feem ntau yog los ntawm fossil fuels. Piv txwv li, 60-watt incandescent teeb tawm txog 450 phaus carbon dioxide (CO₂) dhau nws lub neej. Ib qho sib npaug LED qhov muag teev, ntawm qhov tod tes, tsim tawm tsuas yog 60 phaus ntawm CO₂, qhov txo qis 87%.
Vim lawv lub neej luv luv, cov qhov muag tsis pom kev kuj tsim cov khib nyiab ntau dua. Txhua xyoo, ntau lab tus kub hnyiab-tawm qhov muag teev cua tuaj rau hauv qhov chaw pov tseg, qhov twg cov iav thiab tsis yog-tungsten filaments siv sijhawm ntau xyoo los rhuav tshem. Nrog rau lub neej ntev tshaj 50,000 teev, LEDs tsim 25-50 zaug tsawg pov tseg ib chav tsev ntawm lub teeb. Tsis tas li ntawd, feem ntau ntawmLEDsNws yog qhov zoo dua los siv dua thiab pov tseg vim tias lawv tsis suav nrog cov khoom tsis zoo xws li mercury, uas yog ib qho tseem ceeb ntawm cov laus cov qij fluorescent (CFLs). Txawm hais tias qee tus neeg detractors taw qhia tias LEDs muaj cov kab ntawm cov hlau hnyav (xws li cov hlau lead hauv solder), lawv tau tswj hwm los ntawm cov kev cai thoob ntiaj teb xws li EU Txoj Cai Txwv Tsis Pub Muaj Tshuaj Tiv Thaiv (RoHS) cov lus qhia. LEDs tuaj yeem txo qis lawv qhov kev cuam tshuam ib puag ncig los ntawm kev ua tiav kom rov qab tau cov zaub mov tseem ceeb xws li tooj liab thiab txhuas thaum rov ua kom zoo.
Versatility thiab Light Quality: LEDs Kho kom haum raws li qhov xav tau tam sim no
Cov kev tsim kho niaj hnub no tau tshem tawm qhov hnyav, txias - lub teeb dawb uas cov LEDs thaum ntxov tau paub txog kev tawm. LEDs tam sim no tuaj nyob rau hauv ntau yam xim kub, xws li txias dawb (5,000K–6,500K), uas yog zoo meej rau kev ua hauj lwm teeb pom kev zoo nyob rau hauv lub chaw ua hauj lwm, lub rooj cob qhia, thiab chav ua noj, kom sov dawb (2,700K–3,000K), uas ua raws li qhov sov so, caw lub teeb ci ntawm cov teeb ci. Ntau LEDs kuj muaj kev xaiv dimmable, uas tso cai rau cov neeg siv hloov qhov ci kom haum rau lawv cov kev ua ub no lossis mus ob peb vas. Incandescents kuj muaj qhov ua haujlwm no, tab sis muaj qhov sib txawv loj: Dimming LED txo qis ob lub teeb pom kev zoo thiab kev siv hluav taws xob, thaum dimming lub teeb hluav taws xob txo cov teeb pom kev zoo tab sis tsis txaus siab txo kev siv hluav taws xob.
LEDs yog incredibly ntau yam thiab. Lawv pom nyob rau hauv ob hom loj (xws li lub teeb vaj huam sib luag rau qab nthab lossis teeb pom kev zoo rau sab nraum zoov) thiab me me (siv hauv gadgets zoo li smartphones thiab smartwatches). Muaj tswv yim teeb pom kev zoo, xws li nyob rau hauv - txee teeb hauv chav ua noj, teeb sawb rau cov teeb pom kev zoo hauv chav nyob, lossis xim - hloov LEDs rau thaj chaw lom ze xws li tsev xinesmas, yog tsim los ntawm lawv qhov me me, lub teeb tsim. Nyob rau hauv sib piv, incandescent qhov muag teev tsuas yog muaj nyob rau hauv cov qauv tsim (xws li A19 thiab candelabra) thiab tsis tuaj yeem phim LEDs 'adaptability rau kev siv tshwj xeeb.
Cov Xim Rendering Index (CRI), uas ntsuas qhov zoo ntawm lub teeb pom kev pom cov khoom ntawm cov xim tiag tiag, yog ib qho chaw uas cov qij taws txuas ntxiv kom muaj txiaj ntsig zoo. Nrog rau CRI ntawm 95-100, feem ntau ntawm cov qhov muag teev ua rau cov xim ze li ntawm qhov pom ntawm lub hnub ci ntuj. Cov peev nyiaj- cov phooj ywg LEDs yuav muaj qis dua CRIs (70–80), uas ua rau muaj xim me ntsis, thaum siab -cov LEDs zoo tam sim no muaj CRIs ntawm 90–95, uas cov neeg siv feem ntau tsis tuaj yeem qhia sib nrug ntawm cov teeb pom kev zoo. Qee cov neeg siv tseem nyiam cov khoom siv hluav taws xob rau cov chaw tshaj lij uas cov xim fidelity yog qhov tseem ceeb, xws li cov tsev khaws puav pheej, cov duab kos duab, lossis cov duab thaij duab. Tab sis txawm nyob rau hauv lub lag luam no, siab -kawg LEDs tau sai sai; qee cov qauv twb muaj CRIs ntawm 97 thiab 99.
Incandescent Bulbs 'Kev Siv Tshwj Xeeb
Cov qij taws txuas ntxiv ua haujlwm me me hauv qee lub sijhawm txawm tias muaj txiaj ntsig zoo ntawm LEDs. Ntawm qhov nrov tshaj plaws yog cov teeb pom kev zoo nkauj, xws li qub -fashioned Edison qhov muag teev nrog cov filaments uas tau siv hauv khw noj mov, tsev noj mov, thiab tsev kom ua rau muaj kev xav tsis thoob. Txawm hais tias muaj ntau yam LED sib txawv ntawm cov teeb no, qee cov neeg siv khoom tseem xaiv lub teeb ci ntsa iab thiab ci ntsa iab ntawm qhov muag teev Edison qhov muag teev. Zoo ib yam li qhov no, ntau tus uas txaus siab rau lawv cov kev zoo ib txwm muaj txuas ntxiv nyiam cov teeb Christmas ntoo, tab sis nyob rau xyoo tas los no, LED Christmas teeb- uas muaj zog dua thiab muaj zog-ntau npaum- tau dhau los ua qhov kev xaiv nrov tshaj plaws.
Nyob rau hauv cov xwm txheej thaum tshav kub yog qhov xav tau, qhov muag teev tuaj yeem pab tau. Piv txwv li, lub tshav kub uas tsim los ntawm cov qhov muag teev yog qhov tsim nyog rau kev ua haujlwm ntawm cov khoom siv me me xws li cov teeb pom kev loj hlob, qhov cub countertop, thiab cov tsiaj reptiles enclosures. Rau cov ntawv thov no, qhov muag teev incandescent yog qhov kev xaiv zoo tshaj vim tias LEDs tsim hluav taws xob tsis txaus. Tsis tas li ntawd, thaum qee cov laus dimmers yuav tsis ua haujlwm nrog LEDs (yuav tsum tau hloov kho kim), cov qij taws teeb tau sib xws nrog txhua hom teeb pom kev zoo thiab dimmers yam tsis tas yuav tsum muaj cov xov hlau tshwj xeeb. Cov qhov muag tsis pom kev tuaj yeem yog ib qho luv luv - lub sij hawm kho rau cov uas muaj hluav taws xob qub uas tsis tuaj yeem lossis tsis siv nyiaj rau cov dimmers tshiab.
Hauv kev xaus
LEDsyog qhov kev xaiv zoo tshaj plaws rau yuav luag txhua qhov kev xav tau teeb pom kev zoo thaum cov txiaj ntsig thiab qhov tsis zoo ntawm cov teeb pom kev zoo thiab LED teeb pom kev sib piv. Piv nrog rau qhov muag teeb, lawv muaj kev nyab xeeb ntau dua ib puag ncig, ntev - kav ntev, kev lag luam hauv lub sijhawm, thiab lub zog- ua haujlwm tau zoo. Txawm hais tias qhov muag teev tseem muaj qee zaus siv hauv cov cua sov- cov khoom siv los yog cov teeb pom kev zoo nkauj, cov ntawv thov no tau qis zuj zus raws li cov thev naus laus zis thev naus laus zis tau nce zuj zus thiab ua tus nqi tsim nyog.
