Epoch-ua dimming rau kev txuag hluav taws xob
Txij li thaum tib neeg pom tau hais tias lawv yuav tsum ua txhua yam ua tau kom txuag tau lub zog thiab txo cov emissions kom daws tau qhov teeb meem ceev ntawm huab cua sov, yuav ua li cas txo hluav taws xob siv rau teeb pom kev zoo tau muab tso rau hauv cov txheej txheem ua ib qho teeb meem tseem ceeb. Vim tias qhov hluav taws xob teeb pom kev zoo suav txog 20% ntawm tag nrho cov kev siv hluav taws xob. Hmoov zoo, muaj LEDs nrog kev ua haujlwm siab thiab txuag hluav taws xob. Lub LED nws tus kheej yog ntau tshaj li 5 npaug ntau zog-txuag tshaj li cov teeb incandescent, thiab txog li ob zaug lub zog txuag tshaj li fluorescent teeb thiab lub zog txuag teeb. Nws tsis zoo li lub teeb fluorescent thiab lub teeb txuag hluav taws xob uas muaj mercury. Yog tias koj tuaj yeem siv dimming kom txuag tau lub zog, ces nws kuj yog ib qho tseem ceeb ntawm kev txuag hluav taws xob. Tab sis yav dhau los, tag nrho cov teeb pom kev zoo tsis yooj yim kom ua tiav qhov dimming, thiab yooj yim dimming yog qhov zoo ntawm LED. Vim tias muaj ntau zaus nws tsis tas yuav tsum qhib lub teeb lossis tsawg kawg tsis ci, tab sis cov teeb ci tau qhib heev, xws li teeb pom kev ntawm ib tag hmo mus txog rau kaj ntug; lub teeb nyob rau hauv lub tsheb thaum lub subway tsheb yog tsav los ntawm lub underground mus rau hauv av nyob rau hauv suburbs; Feem ntau Cov teeb fluorescent ntawm cov chaw ua haujlwm, tsev kawm ntawv, chaw ua haujlwm, thiab lwm yam nyob ze ntawm lub qhov rais tseem nyob rau ntawd thaum lub hnub ci ntsa iab. Cov chaw no tsis paub tias siv zog npaum li cas txhua hnub! Yog li ntawd, rau qhov dimming ntawm lub teeb thiab teeb, dimming ntawm phab ntsa hauv tsev tsis yog daim ntawv thov tseem ceeb, thiab kev ua lag luam kuj tseem me me. Hloov chaw, raws li qhov xav tau dimming ntawm txoj kev teeb, chaw ua haujlwm, khw khw, tsev kawm ntawv, thiab cov chaw tsim khoom yog lub sijhawm tseem ceeb dua. Tsis tsuas yog lub lag luam loj, tab sis nws kuj txuag tau ntau lub zog. Dab tsi yog qhov xav tau rau cov sijhawm no tsis yog phau ntawv dimming tab sis tsis siv neeg dimming thiab ntse dimming!
