Nws feem ntau hnov tias LED teeb muaj lub zog ntau dua li cov teeb fluorescent thiab incandescent yav dhau los, tab sis vim li cas kuv lub teeb siv zog ntau heev? Kuv ib zaug sim txiav tawm lub zog ntawm tag nrho cov khoom siv hluav taws xob thiab tig lub teeb rau 5 teev tsis tu ncua. Lub 'meter' qhia tau hais tias nws siv 3 kWh.
Qhov tseeb nyob ntawm no, LED teeb puas tuaj yeem txuag hluav taws xob? Cov lus teb yog: nws txuag hluav taws xob!
Lub teeb LED puas txuag hluav taws xob?
Ua ntej sib tham txog qhov teeb meem ntawm kev txuag hluav taws xob, peb yuav tsum xub txiav txim siab tias "lub zog txuag" yog dab tsi.
"Kev txuag hluav taws xob" hauv qhov nqaim yog hais txog "kev siv hluav taws xob tsawg." Ib yam yog qhib rau 1 teev, koj haus 1 kWh ntawm hluav taws xob, Kuv haus 2 kWh, koj txuag hluav taws xob tshaj kuv.
Tab sis ntawm cov khoom siv hluav taws xob, tshwj xeeb tshaj yog cov lus hais, lub ntsiab lus ntawm "kev txuag hluav taws xob" tau hloov pauv. Peb feem ntau hu ua "kev ua haujlwm siab" "lub zog txuag".
Piv txwv li, yog hais tias ob tug neeg tsiv cib, A noj 1 steamed bun thiab tsiv 10 cib; B noj 2 lub ncuav thiab txav 30 cib. Txawm hais tias B noj ntau dua steamed buns dua A, B muaj txiaj ntsig zoo, yog li B tau hais tias "muaj zog ntau dua."
Tib yam muaj tseeb rau cov teeb. LED teeb "txuag lub zog" vim tias lawv ua haujlwm zoo dua. Nrog tib lub ci ci ntawm lub teeb, kev siv lub zog ntawm LED teeb qis dua li ntawm cov teeb fluorescent thiab cov teeb incandescent. Siv tib lub zog, lub teeb tawm los ntawm LED teeb yog ci dua li cov teeb fluorescent thiab cov teeb incandescent.
Yog li tus yuam sij yog nyob rau hauv "brightness"! Yog vim li cas vim li cas peb xav tias niaj hnub no lub teeb LED tsis txaus los txuag lub zog yog vim peb muaj kev thov siab rau qhov ci. Thaum tsaus ntuj, txhua lub tsev ci ntsa iab zoo li nruab hnub, thiab lub zog siv hluav taws xob yog qhov siab. Yog tias koj xav siv cov teeb ci incandescent thiab cov teeb fluorescent kom ua tiav qhov ci ntsa iab, kuv ntshai tias yuav siv hluav taws xob ntau dua.
Tom qab tham txog lub luminous lub cev (LED), peb tham txog kev tsim lub teeb. Qhov tsim teeb meem ntawm lub teeb yuav cuam tshuam qhov ci ntawm lub teeb. Txhawm rau kom tau txais cov teeb ci ci dua, peb yuav tsum hloov lub teeb ci dua, uas siv hluav taws xob ntau dua. Txhawm rau muab nws bluntly, nws yog "kev tsim tsis raug, kom lub teeb emissions los ntawm lub teeb yog nkim, txo cov efficiency ntawm lub teeb".
