Dab tsi yog qhov ntsuas rau kev txiav txim siab qhov zoo ntawm cov teeb pom kev zoo sab hauv tsev LED?
Hauv lub sijhawm teeb pom kev zoo ntawm LED, kev teeb pom kev zoo ntawm cov teeb tau dhau los ua qhov tseem ceeb dua. Cov teeb tau hloov kho tas li thiab hloov pauv tas li. Thaum yuav cov teeb, peb kuj yuav tsum tau xyuam xim rau lawv. Yog li dab tsi yog cov ntsuas ntsuas ntsuas qhov pom kev zoo ntawm LED teeb? Cia' saib!
Dab tsi yog qhov ntsuas rau kev txiav txim siab qhov zoo ntawm cov teeb pom kev zoo sab hauv tsev LED?
1. Xim kub. Cov xim kub yog qhov ntau ntawm lub cev uas piav qhia xim ntawm lub teeb pom kev, thiab nws chav nyob yog K (Kelvin). Yog tias nws yog teeb pom kev hauv tsev, xim kub feem ntau yog nruab nrab ntawm 2800K-6500K. Feem ntau hais lus, kev faib hluav taws xob ntawm cov roj teeb thiab cov teeb LED zoo dua li cov teeb hluav taws xob sodium siab thiab cov teeb roj fluorescent, tab sis cov roj teeb hluav taws xob siv hluav taws xob ntau dua, yog li cov teeb ci LED yuav dhau los ua qhov kev xaiv zoo tshaj plaws.

2. Xim rendering. Kev ua xim hais txog cov yam ntxwv ntawm cov xim sib txawv uas lub teeb pom kev sib txawv sib txawv ci rau ntawm cov khoom ntawm tib xim. Qhov ntsuas xim xim (Ra) feem ntau yog siv los qhia cov xim ua haujlwm ntawm lub teeb ci. Ra ranges ntawm 0-100. Qhov ze tus nqi Ra yog rau 100, qhov siab dua cov xim ua haujlwm. Feem ntau hais lus, siab dua cov xim ua piv txwv ntawm LED teeb pom kev zoo, qhov ua tau zoo dua nws cov xim ua haujlwm tau zoo.
Rau cov teeb pom kev ntawm LED, cov xim ua kom siab dua, tus nqi ntau dua ntawm lub teeb ci LED, yog li qhov ua tau zoo ntawm lub teeb pom kev zoo dua. Yog li, qhov zoo ntawm lub teeb ci LED tuaj yeem txiav txim los ntawm kev ua xim.
3. Luminous efficiency. Luminous efficiency yog qhov ntsuas ntawm lub teeb ci. Nws yog qhov sib piv ntawm cov teeb pom kev zoo rau lub zog. Chav tsev yog lm/w (lumens ib watt). Qhov ntau dua qhov ci ci, qhov siab dua qhov ci ntawm lub teeb ci. Yog li ntawd, cov khoom lag luam teeb pom kev zoo nrog kev ua kom pom kev zoo muaj qhov teeb pom kev zoo zoo.
4. Kev txuag hluav taws xob kev ua tau zoo. Kev txuag hluav taws xob yog qhov ntsuas tseem ceeb ntawm peb cov teeb pom kev zoo hauv LED, thiab nws tseem ua tau raws li tus qauv qis ntawm lub neej. Cov teeb meem cuam tshuam nrog kev txuag hluav taws xob ntawm cov teeb LED suav nrog: lub zog ua haujlwm ntawm LED tsav lub zog muab hluav taws xob, kev ua kom sov ua kom sov ntawm lub teeb ci LED, ua kom pom kev zoo thiab lwm yam.
Hauv ntej, txhawm rau ntsuas qhov zoo ntawm cov teeb pom kev zoo sab hauv tsev, ib tus yuav tsum tsis tsuas yog saib ntawm ib sab yam, tab sis tsuas yog los ntawm kev sib txuas ua ke peb tuaj yeem xaiv qhov zoo tshaj plaws teeb pom kev zoo LED.
