Ib Daim Ntawv Qhia Txog Kev Coj Ua Teeb Pom Kev Hauv Chaw Nyob
Taw qhia
Kev siv cov kev xaiv teeb pom kev zoo LED tau nthuav dav. Ntau cov khoom siv LED thiab cov kev xaiv tam sim no nyob rau hauv kev ua lag luam ntau dua li yav dhau los rau cov pa roj carbon monoxide thiab lub zog txuag hluav taws xob compact fluorescent (CFL) teeb.
Txawm hais tias qee cov khoom lag luam LED tsuas yog zoo ib yam li lwm lub teeb pom kev zoo lossis lub raj fluorescent, hloov mus rau LED teeb pom kev zoo yuav nyuaj heev vim muaj ntau yam khoom, cov ntsiab lus tshiab tsim los ntawm kev lag luam teeb pom kev zoo, thiab qhov tseeb tias LEDs siv cov thev naus laus zis sib txawv li cas. peb tau accustomed mus rau xyoo lawm.
Tsab ntawv xov xwm no qhia txog kev xaiv cov khoom lag luam rau ntau qhov chaw hauv thaj chaw nyob, txhais cov ntsiab lus "yuav tsum paub" uas cov tswv tsev lossis cov neeg cog lus yuav tsum paub txog thaum yuav cov khoom siv LED, thiab qhia txog qee qhov pitfalls kom zam thiab paub txog. ua kom txoj kev hloov mus rau LED teeb pom kev zoo.
Dab tsi txhawb qhov hloov mus rau LED?
Lawv tsis tsuas yog muaj zog ntau dua li lwm txoj hauv kev xws li incandescent thiab CFLs, tso cai rau kev txuag hluav taws xob tseem ceeb, tab sis lawv kuj muaj lub neej ntev dua, tsis muaj mercury zoo li CFLs, thiab muaj ntau txoj kev xaiv rau qhov ci thiab lub teeb pom kev zoo. . (sov vs. txias).
Txhua lub tsev tshiab lossis kev hloov kho tshiab hauv Kalifonias yuav tsum ua raws li 2013 California Energy Efficiency Standard, tseem hu ua Title 24. Cov qauv siv hluav taws xob nruj uas tau teev tseg hauv cov qauv no tuaj yeem ua tau raws li lossis txawm tias dhau ntawm cov khoom siv LED.
Tsis tas li ntawd, LEDs muaj nyob rau hauv cov duab uas tsis yog lub teeb classic. Vim lawv qhov me me thiab ntau yam ntawm cov duab, qhov ntau thiab tsawg, thiab kev siv, LED illumination xaiv tso cai rau ntau yam tsis muaj kev txwv tsis pub siv hauv tsev.
Terminology
Thaum muas lub teeb pom kev zoo, txhua yam uas yuav tsum tau xav txog yog lub teeb lub teeb, wattage, uas sawv cev rau qhov ci ntsa iab ntawm lub teeb, thiab lub hauv paus loj, uas ua kom ntseeg tau tias lub teeb yuav haum rau lub teeb.
Nrog CFLs, cov neeg siv khoom tam sim no muaj kev xaiv ntawm lub teeb pom kev zoo uas feem ntau hu ua mos dawb, ci ntsa iab, thiab nruab hnub. Ci dawb thiab nruab hnub nrig yog qhov ntse dua thiab txias dua nrog lub ntsej muag xiav, thaum mos dawb muaj lub suab sov zoo ib yam li lub teeb incandescent.
Peb lub tswv yim yog qhov tseem ceeb rau kev nkag siab thaum siv LEDs.
1. Kev ci ntsa iab
2. Lub teeb pom kev zoo
3. Xim xim
Peb xav kom paub tseeb tias peb tab tom yuav cov khoom tsim nyog rau txoj haujlwm vim tias cov khoom siv LED tseem raug nqi ntau dua li cov khoom siv hluav taws xob zoo sib xws thiab yuav muaj lub neej ntev dua.
Brightness:
Ua ntej ntawm tag nrho cov, peb yuav tsum dispel lub tswvyim hais ua dabneeg uas lub hwj chim sib npaug rau luminosity. Txij li cov khoom siv LED siv ntau lub zog tsawg (Watts) dua li qhov muag teeb, nws yog qhov nyuaj rau kev sib piv cov luminosity ntawm lub teeb thiab LED teeb raws li wattage. Wattage thiab brightness rau incandescent qhov muag teev tau ua, txawm li cas los xij, muaj kev sib txuas meej.
Lumens yog tib qho kev txiav txim siab thaum ntsuas lub teeb ci LED lub luminosity. Lub lumen, ib chav tsev ntawm kev ntsuas qhov ci, qhia tias lub teeb ci ntau npaum li cas ib yam khoom illumination tsim.
Rau kev sib piv, ib txwm 60 W incandescent teeb tsim txog 800 lumens.
Luminous tsos:
Hauv kelvin, cov xim zoo nkauj ntawm lub teeb yog suav raws li qhov sib txuam xim kub (CCT). (K). Peb yuav tsum tshawb nrhiav tus lej kelvin los txiav txim seb lub teeb pom kev zoo lossis lub teeb ua rau lub teeb sov los yog ntse dua, lub teeb txias dua. Lub teeb yuav saib sov dua tus lej qis dua, thiab txias dua thiab ntau dua bluish ntau dua tus lej. Cov xim kub ntawm tus qauv incandescent teeb yog li ntawm 2700K txog 3000K. Nyob rau hnub ntshiab, lub hnub thaum nruab nrab emits illumination uas yog hais txog 5500K.
Cov neeg feem ntau thuam CFL teeb kom muaj qhov txias dua, saib xyuas ntau dua li qhov muag teev. Qhov teeb meem ntawm no yog tias lawv xaiv qhov txias, siab-kelvin xim es tsis yog qhov sov.
Xim raug:
Koj puas tau mus yuav khoom thiab xav tias koj yuav yog xim-dig muag vim koj tsis tuaj yeem qhia tau tias cov khoom ntawm cov khaub ncaws uas koj tab tom pom yog ntsuab tsaus lossis xiav? Yog tias muaj, lub khw muag khoom teeb pom kev tsis tuaj yeem qhia cov xim kom raug rau koj.
Lub peev xwm ntawm ntau qhov chaw teeb pom kev "ua kom raug" qhia cov khoom xim txawv. Thiab los ntawm qhov kom zoo, peb xa mus rau hauv kev sib piv rau lub teeb ci incandescent lossis lub teeb pom kev zoo li lub hnub.
Xim sawv cev Index, los yog luv luv CRI, yog ib qho kev ntsuas ntawm cov xim sawv cev. Qhov ntsuas qhov ntsuas ntawm 0 mus txog 100. Lub CRI ntawm 2700K incandescent teeb yog 100.
Nrog rau niaj hnub siv tshuab LED, tus lej CRI saum 80 yog suav tias yog qhov zoo heev thiab yuav tsim nyog rau feem ntau ntawm cov ntawv thov. Peb piav qhia txog vim li cas cov xim zoo dua ntawm 90 lossis siab dua tuaj yeem nyiam rau qee thaj tsam hauv ntu hauv qab no.
