Thaum nrhiav LED qhov muag teev, peb lub ntsiab lus tshwj xeeb koj yuav ntsib yog Lumens, Kelvin, thiab Watts. Txawm hais tias feem ntau cov neeg siv khoom tau paub txog lub sij hawm Watts vim yog lub teeb pom kev zoo nyob thoob plaws lub ntiaj teb, ntau tus tsis paub meej tias Lumens thiab Kelvin hais txog dab tsi. Tsis txhob txhawj yog tias nws yog rooj plaub rau koj thiab. Peb muaj koj rov qab. Peb mam li muab qhov av rau koj ntawm peb lo lus hauv tsab ntawv no.
Zoo, huh? Tam sim no cia peb pib.
Lumens
Lumens ntsuas lub teeb qhov muag tag nrho ntawm lub teeb. Hauv lwm lo lus, nws yog ib qho kev ntsuas ntawm lub teeb ci. Lub teeb yuav muab lub teeb ci dua yog tias qhov kev nyeem lumen siab dua, thiab rov ua dua.
Thaum muas lub teeb tshiab, koj yuav tsum saib lumens es tsis yog watts vim lumens qhia tias lub teeb ci li cas.
Nov yog qee yam uas yuav tsum nco ntsoov thaum mus yuav khoom rau LED qhov muag teev vim tias qhov ci ntawm lub teeb tso rau hauv koj lub tsev yuav txawv txav:
Xaiv ib lub teeb LED uas ua rau kwv yees li 1600 lumens yog tias koj xav hloov 100 watt incandescent noob.
Yog tias koj xav hloov lub teeb hluav taws xob 75 watt, nrhiav lub teeb ci LED uas muaj nyob ib ncig ntawm 1100 lumens.
Yog tias koj xav hloov lub teeb 60 watt incandescent, nrhiav ib lub teeb LED nrog ib ncig ntawm 800 lumens.
Yog tias koj xav hloov lub teeb 40 watt incandescent, nrhiav ib lub teeb LED nrog ib ncig ntawm 450 lumens.
Kelvin
Cov xim kub ntawm lub teeb los yog lwm yam teeb pom kev zoo yog qhia hauv Kelvin. Cov cua txias yog cov uas muaj Kelvin kub ntawm 3600K thiab 5000K. Cov xim kub qis dua, ntawm qhov tod tes, pom tias sov (2700k txog 3000k). Lub teeb txias yog qhov zoo dua rau kev ua haujlwm pom vim nws tsim qhov sib txawv ntau dua li qhov sov sov. Lub teeb sov so, ntawm qhov tod tes, feem ntau yog ua haujlwm hauv thaj chaw nyob vim tias nws muaj kev thaj yeeb nyab xeeb dua. Cov xim kub ntawm 2700K thiab 3600K yog pom zoo rau feem ntau ntawm cov teeb pom kev zoo sab hauv. Tau hais tias, koj tuaj yeem xav txog txias dawb LED qhov muag teev rau kev ua haujlwm illumination. Lawv kuj tuaj yeem yog qhov kev xaiv zoo dua rau cov chaw nres tsheb lossis chaw ua haujlwm hauv tsev.
Watts
Watts yog siv los ntsuas kev siv hluav taws xob. Nyob rau hauv cov ntaub ntawv ntawm incandescent teeb, brightness thiab wattage yog ncaj qha correlated. Lub tom kawg nce nyob rau hauv tandem nrog tus qub. Txawm li cas los xij, txij li cov teeb ci LED siv ntau lub zog tsawg dua li lawv cov neeg ua ntej tau ua, koj yuav tsum ntsuas ib lub teeb tag nrho cov zis hauv lumens es tsis yog watts.
Lus nug thiab lus teb
Puas yog lub teeb uas muaj xim kub dua emit ntau lub teeb?
Kelvin yog ib qho ntawm feem ntau hais cov qauv rau LED teeb. Ntau tus neeg siv khoom yuam kev ntseeg tias lub teeb LED yuav ci dua yog tias qhov ntsuas Kelvin ntau dua.
Tab sis cov zis ntawm lub teeb tsis muaj dab tsi ua nrog Kelvin. Nws yog hais txog lub teeb ntawm lub teeb. Lumens, tsis yog Kelvin, yog siv los ntsuas tag nrho cov teeb pom kev zoo. Txhawm rau txiav txim siab seb lub teeb ci LED yuav zoo li cas, koj yuav tsum saib nws qhov ntsuas lumen.
2700K txog 3000K qhov muag teev yuav tsum txaus rau feem ntau ntawm cov teeb pom kev zoo hauv ib lub tsev txij li thaum lawv ua haujlwm los tsim kom muaj kev thaj yeeb nyab xeeb. Txawm li cas los xij, tej zaum koj yuav xav siv cov qij LED nrog tus nqi Kelvin ntau dua hauv qee qhov chaw, tshwj xeeb tshaj yog thaum koj xav tau kev ua haujlwm illumination.
Lub 5000K LED teeb tseem yuav feem ntau zoo dua li lub teeb 2700K, tab sis qhov no yog vim qhov qub tsim teeb pom kev zoo sib xws.
Yuav ua li cas kuv thiaj paub tias muaj pes tsawg lumens sib npaug ib kelvin?
Tsis muaj kev sib txuas ntawm ob qhov kev nyeem ntawv no. Yog li, nws yuav tsis raug xav tias ib qho tshwj xeeb Kelvin yuav sib npaug ntawm qee tus lej ntawm lumens.
Qhov twg yog qhov ci ntsa iab dua, 2700 Kelvin lossis 5000 Kelvin?
Es tsis txhob ci, Kelvin ntsuas xim kub. Lumens yog qhov tsim nyog ntsuas ntsuas rau qhov ci. Lub 5000K LED teeb feem ntau yuav zoo dua li lub teeb 2700K, tab sis qhov ntawd yog vim qhov sib txawv ntxiv.
