LED teeb pom kev zoo tau dhau los ua kev lag luam muaj zog hauv Suav teb vim nws qhov zoo ntawm kev tiv thaiv ib puag ncig thiab kev txuag hluav taws xob. Txoj cai txwv txwv qhov muag teev tau raug coj los ua raws li cov kev cai cuam tshuam, uas tau coj cov kev lag luam teeb pom kev zoo ib txwm muaj los sib tw hauv kev lag luam LED. Niaj hnub no, kev ua lag luam tab tom loj hlob sai. Yog li, dab tsi yog qhov kev txhim kho ntawm LED cov khoom hauv ntiaj teb?

Raws li cov ntaub ntawv txheeb xyuas, lub ntiaj teb teeb pom kev siv hluav taws xob siv nyiaj rau 20% ntawm tag nrho cov khoom siv hluav taws xob txhua xyoo, txog li 90% hloov mus rau kev siv hluav taws xob kub, uas tsis tsuas yog tsis muaj txiaj ntsig nyiaj txiag. Los ntawm qhov kev xav ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, LED teeb pom kev zoo tau dhau los ua cov cuab yeej siv siab thiab kev lag luam. Lub caij no, tsoomfwv thoob plaws ntiaj teb tab tom nquag tsim cov kev cai ib puag ncig kom txwv tsis pub siv cov qij taws. Cov teeb pom kev zoo ib txwm muaj tau nthuav tawm cov teeb pom kev tshiab LED, ua kom nrawm tsim cov qauv lag luam tshiab. Kev txhawb nqa los ntawm ob qho kev nyiam ntawm kev ua lag luam thiab cov kev cai, LED tau tsim sai sai thoob ntiaj teb.

Qhov zoo ntawm LED muaj ntau heev, nrog kev ua haujlwm siab luminous thiab ntev lifespan. Nws cov luminous efficiency tuaj yeem ncav cuag 2.5 npaug ntawm cov teeb fluorescent thiab 13 npaug ntawm cov roj teeb incandescent. Lub luminous efficiency ntawm incandescent teeb yog tsawg heev, tsuas yog 5% ntawm hluav taws xob hluav taws xob hloov mus rau hauv lub teeb lub zog, thiab 95% ntawm hluav taws xob hluav taws xob hloov mus rau hauv lub tshav kub zog. Cov teeb fluorescent kuj zoo dua li cov teeb pom kev zoo, vim lawv hloov 20% mus rau 25% ntawm cov hluav taws xob hluav taws xob rau hauv lub teeb lub zog, tab sis kuj nkim 75% mus rau 80% ntawm hluav taws xob hluav taws xob. Yog li los ntawm qhov kev xav ntawm kev siv hluav taws xob, ob qho tib si ntawm cov teeb pom kev zoo no tau dhau los lawm.

Cov txiaj ntsig tsim los ntawm LED teeb pom kev zoo kuj tseem suav tsis tau. Nws tau tshaj tawm tias Australia yog thawj lub teb chaws hauv ntiaj teb los qhia txog cov kev cai txwv tsis pub siv lub teeb pom kev zoo hauv xyoo 2007, thiab European Union kuj tau tshaj tawm cov cai ntawm phasing out incandescent qhov muag teev nyob rau lub Peb Hlis 2009. Yog li ntawd, ob lub tuam txhab teeb pom kev lag luam tseem ceeb, Osram. thiab Philips, tau nrawm lawv qhov teeb tsa hauv thaj chaw ntawm LED teeb pom kev zoo hauv xyoo tas los no. Lawv txoj kev nkag tau txhawb txoj kev loj hlob sai ntawm LED teeb pom kev lag luam thiab tseem ua kom nrawm nrawm ntawm lub ntiaj teb LED thev naus laus zis kev nce qib.

Txawm hais tias kev lag luam LED tab tom txhim kho zoo hauv thaj chaw teeb pom kev zoo, qhov tshwm sim ntawm homogenization tau dhau los ua pom tseeb, thiab nws tsis tuaj yeem tsim ntau hom kev tsim tshiab. Tsuas yog los ntawm kev ua tiav cov no tuaj yeem ua kom ruaj khov hauv kev lag luam LED.
