Thaum nws los txog rau lub teeb pom kev ntawm lub tsev rau khoom, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov xim kub ntawm lub teeb. Cov xim kub yog hais txog xim lossis xim ntawm lub teeb, uas ntsuas hauv Kelvin (K). Cov xim sib txawv tuaj yeem cuam tshuam rau tej yam xws li cov neeg ua haujlwm tsim khoom, kev nyab xeeb, thiab kev siv hluav taws xob. Yog li, dab tsi yog lub teeb xim zoo tshaj plaws rau lub tsev khaws khoom?
Ua ntej, nws yog ib qho tseem ceeb kom paub tias tsis tas yuav yog ib qho "zoo tshaj" xim teeb rau txhua lub tsev khaws khoom. Cov kev xav tau tshwj xeeb ntawm koj lub tsev khaws khoom yuav txiav txim siab qhov zoo tshaj plaws xim kub. Txawm li cas los xij, muaj qee cov lus qhia dav dav uas tuaj yeem pab koj xaiv qhov yog.
Ib qho kev txiav txim siab tseem ceeb yog hom kev ua haujlwm hauv lub tsev rau khoom. Yog tias koj cov neeg ua haujlwm yuav tsum tuaj yeem pom cov xim kom raug (piv txwv li, yog tias lawv xaiv cov khoom raws li cov xim xim), ces qhov ntsuas xim siab (CRI) yog qhov tseem ceeb. CRI ntsuas qhov zoo ntawm lub teeb pom kev pom xim, nrog qhov ntsuas siab dua qhia qhov tseeb xim zoo dua. Rau cov haujlwm no, cov xim kub ntawm ib ncig ntawm 5000K txog 6500K tau pom zoo, vim qhov no suav tias yog "hnub ci" xim uas qhia cov xim kom raug.
Ntawm qhov tod tes, yog tias cov neeg ua haujlwm tau ua haujlwm uas tsis xav tau cov xim kom raug (xws li kev xaiv yooj yim thiab ntim khoom), ces qhov qis dua CRI tau txais. Qhov tseeb, qee qhov kev tshawb fawb tau qhia tias qhov qis dua CRI (ib puag ncig 3000K) tuaj yeem ua tau yooj yim dua rau cov neeg ua haujlwm, vim nws tsim kom muaj huab cua sov dua, muaj kev caw ntau dua.
Lwm qhov yuav tsum tau xav txog yog kev siv hluav taws xob. Cov xim kub siab dua (siab dua 5000K) zoo li yuav muaj zog ntau dua li cov xim kub qis, vim lawv tsim lub teeb ntau dua ib watt ntawm hluav taws xob siv. Qhov no txhais tau hais tias yog tias koj muaj lub tsev khaws khoom loj uas xav tau ntau lub teeb pom kev zoo, xaiv cov xim kub dua tuaj yeem pab koj txuag cov nqi hluav taws xob hauv lub sijhawm ntev.
Thaum kawg, lub teeb xim zoo tshaj plaws rau koj lub tsev khaws khoom yuav nyob ntawm koj qhov kev xav tau tshwj xeeb. Tham nrog tus kws tshaj lij teeb pom kev zoo lossis tus neeg muag khoom los pab koj xaiv qhov zoo xim kub thiab teeb pom kev zoo rau koj qhov chaw.
