Nws yooj yim Ua Ntsuab: Cia Muaj "LED" Lub Teeb
Nws yog qhov xav tsis thoob tias Thomas Edison muaj peev xwm ua tau zoo rau thawj lub teeb pom kev zoo rov qab rau xyoo 1879! Wow, nws kav ntev li 13.5 teev! Nws yog qhov xav tsis thoob uas cov qij taws tau hlawv rau 131 xyoo! Txawm li cas los xij, tam sim no peb tuaj yeem hloov mus rau ntau lub zog-txuag kev xaiv uas zoo dua rau peb lub hnab nyiaj thiab ib puag ncig.
LEDs thiab lwm yam kev xaiv lub zog txuag hluav taws xob tau dhau los ua neeg nyiam thiab dav siv. Lawv ua haujlwm ntawm 20 feem pua kev ua tau zoo, uas txhais tau tias tseem muaj chaw rau kev txhim kho kom lawv ua tau zoo. Lub teeb ci incandescent tuaj yeem kav ntev txog 5, 000 teev, uas yog kwv yees li ib xyoos.
LEDs tau dhau los ua neeg nyiam thiab tej zaum yuav yog lub neej yav tom ntej ntawm teeb pom kev zoo, txawm tias qhov muag teev tau dhau los ua tsawg dua. LED qhov muag teev yog qhov kev xaiv zoo vim tias lawv muaj txiaj ntsig zoo, muaj txiaj ntsig zoo nyob rau lub sijhawm ntev, thiab tus phooj ywg zoo ib puag ncig vim lawv siv hluav taws xob tsawg. LED qhov muag teev muaj kev ua neej zoo nyob ib puag ncig 50, 000 teev, lossis txog 10 xyoo, uas yog 10 npaug ntev dua li lub teeb incandescent! Txawm hais tias tus nqi nce siab dua, lub neej ntev ntawm cov khoom yuav ua rau muaj txiaj ntsig zoo ntawm kev hloov lub teeb, kev khiav hauj lwm thiab kev saib xyuas cov nqi, thiab cov khoom pov tseg tsawg dua hauv qhov chaw pov tseg.
LED qhov muag teev yog amazing! Lawv ua tiav 80 feem pua kev ua tau zoo thiab tsuas yog tso 20 feem pua ntawm lawv lub zog raws li cua sov. LED qhov muag teev yog qhov kev xaiv zoo vim tias lawv siv lub zog tsawg dua thiab muaj txiaj ntsig zoo dua. LEDs muaj peev xwm loj heev los txo peb cov kev siv hluav taws xob tag nrho, los ntawm tsev neeg ib leeg mus rau qhov pom kev ntawm tag nrho lub tsev.
Nws yog qhov zoo uas lawv tab tom nrhiav tau yooj yim dua! Nws yog qhov zoo uas cov teeb ci LED tau yooj yim muaj nyob hauv online thiab hauv khw muag khoom xws li Home Depot! Xov xwm zoo siab heev! Lub Tsev Depot tam sim no muab ntau yam khoom siv hluav taws xob pheej yig LED ob qho tib si hauv khw thiab hauv online. Qhov no yog lub sijhawm zoo rau tib neeg hloov mus rau kev xaiv teeb pom kev zoo dua. $20 tej zaum yuav zoo li ntau, tab sis tsuas yog xav, yog tias lub teeb ntawd kav ntev txog 10 xyoo, nws yuav tsim nyog rau lub sijhawm ntev!
Nws yog amazing kom pom ntau npaum li cas LEDs tau dhau los ua ib feem ntawm peb lub neej txhua hnub! Nws yog amazing npaum li cas ubiquitous lawv! Lawv tuaj yeem pom nyob rau hauv cov lej xov tooj, cov chaw taws teeb tswj, Christmas teeb, thiab txawm siv ua ke hauv qee lub teeb tsheb. Siv lawv cov kev siv ntawm qhov ntsuas loj dua yuav muaj txiaj ntsig zoo heev!
Pittsburgh yog ib qho piv txwv zoo! Lub nroog tab tom tshawb nrhiav qhov muaj peev xwm ntawm kev hloov kho 40, 000 high-pressure sodium teeb txoj kev teeb kom muaj zog ntau dua LED txoj kev teeb. Los ntawm kev ua kom lub zog txuag hluav taws xob no, peb tuaj yeem txuag tau $ 1 lab hauv cov nqi hluav taws xob, $ 700, 000 hauv kev saib xyuas, thiab txo qis carbon dioxide emissions los ntawm 6,818 tons!
Txawm hais tias tus nqi ntawm LEDs tau ua rau muaj kev cuam tshuam rau lawv txoj kev siv dav, nws yog qhov zoo kom pom tias cov nqi tau poob sai dua li qhov xav tau. Xov xwm zoo heev! LED teeb qhov muag teev (ib qho sib npaug rau 40-watt incandescent teeb) tam sim no raug nqi qis dua $ 30, ntau dua li cov kws tshaj lij tau kwv yees. Hmoov zoo, lawv tau yuam kev. (2012 kuj yog xyoo uas tseemfwv txoj cai lij choj txwv kev tsim khoom ntawm qee yam ntawm cov teeb pom kev zoo hauv lub xeev, thiab los ntawm 2014 feem ntau cov qij incandescent yuav raug txiav, txuas ntxiv lub hom phiaj ntawm LED teeb.)
Yog tias koj tab tom nrhiav kev xaiv pheej yig dua, CFLs yog lwm txoj hauv kev zoo rau LEDs. Lawv kuj muaj txiaj ntsig ntau dua li qhov muag teev!
Los ntawm kev hloov mus rau LED teeb hauv koj lub tsev, chaw ua haujlwm, lossis ntawm txoj kev hauv koj lub nroog, koj tuaj yeem ua rau muaj kev cuam tshuam zoo rau ib puag ncig los ntawm kev txo qis kev siv hluav taws xob thiab emissions. Tsis tas li ntawd, LED teeb tsis muaj mercury, uas yog lwm qhov txiaj ntsig zoo rau ib puag ncig. Nco ntsoov qhia cov txiaj ntsig ntawm LED teeb pom kev zoo nrog koj cov phooj ywg thiab cov neeg nyob ze! Lawv yuav zoo siab los kawm txog qhov cuam tshuam zoo uas nws tuaj yeem muaj rau ib puag ncig. Koj muaj sijhawm los qhia koj txoj kev paub thiab nthuav tawm qhov zoo.
