Incandescent teeb pom kev zoo tau dhau los ua qhov tsis siv tau raws li kev lag luam thiab lub zog txuag teeb pom kev zoo siv lawv qhov chaw.
Feem ntau cov kws tshaj lij tam sim no qhia txog kev siv lub teeb-emitting diodes (LEDs) lossis compact fluorescent teeb (CFLs) los teeb koj lub tsev. Qhov twg ntawm ob lub teeb, txawm li cas los xij, zoo dua? Yam twg yog tus phooj ywg environmentally? CFLs thiab LEDs muaj txiaj ntsig dab tsi?
Peb tau piav qhia qee qhov kev sib txawv tseem ceeb ntawm CFLs thiab LEDs txhawm rau teb cov lus nug no.
LEDs thiab CFLs ua haujlwm li cas?
Thawj qhov sib txawv ntawm CFLs thiab LEDs yog nyob rau hauv txoj kev uas lub teeb tsim.
CFLs yog ib yam uas koj tau pom txawm tias koj tsis tau hnov txog lawv ua ntej. Xav txog lub raj curly hauv ib lub teeb. Nov yog qhov lawv ua haujlwm:
CFL emits ultraviolet lub teeb thaum lub zog xa los ntawm lub raj uas muaj argon thiab mercury, ob yam khoom. Thaum tsis pom ntawm tib neeg lub qhov muag, qhov hluav taws xob ultraviolet no ua rau lub fluorescent txheej (phosphor) hauv lub raj, uas pib tsim lub teeb pom kev tom qab lub sijhawm luv luv. CFLs haus ib ncig ntawm 70 feem pua tsawg zog dua li cov teeb pom kev zoo ib txwm siv thaum lawv ua haujlwm, thaum lawv xav tau ntau lub zog pib dua li lawv ua haujlwm thiab siv sijhawm ob peb feeb kom sov.
CFL teeb
Thaum LEDs yog ib qho kev txhim kho tsis ntev los no hauv cov cuab yeej teeb pom kev zoo, tej zaum koj twb tau pom lawv siv ntau yam khoom, suav nrog LED Christmas teeb, digital watches, plasma TV, thiab lwm yam zaub. Nov yog qhov lawv ua haujlwm:
Ib qho hluav taws xob tam sim no raug xa los ntawm diode, ib yam khoom siv hluav taws xob, kom tig rau LED. Lub teeb yog tsim thaum cov hluav taws xob tam sim no lub electrons txav los ntawm semiconductor. Tsis yog qhov yooj yim heev? Kev ua tau zoo ntawm LEDs tau hais tias ze li ntawm 90 feem pua siab dua li cov teeb pom kev zoo, tab sis txog rau tam sim no, lawv kuj tseem kim dua me ntsis.
CFLs piv rau LEDs: Dab tsi yog qhov zoo tshaj qhov muag teev?
Hauv kev xaus, nws zoo li LEDs muaj qhov tseem ceeb ntawm CFLs hauv yuav luag txhua qhov chaw. Ob leeg yog cov kev xaiv zoo heev, tab sis LEDs yog qhov kev xaiv zoo tshaj plaws yog tias koj xav tau lub teeb zoo tshaj plaws thiab kev lag luam hauv khw. Nrhiav LEDs ntawm koj lub lag luam hauv zos yog tias koj xav teeb lub teeb hauv pem teb lossis ntxiv cov teeb pom kev zoo dua qub.
