Kev siv hluav taws xob thiab kev ua haujlwm luminous

Luminous kev ua tau zoo yog ib qho kev ntsuas ntawm qhov ua tau zoo ntawm lub teeb pom kev zoo thiab yog qhov piv ntawm cov teeb pom kev zoo ntawm lub teeb (lumens) rau nws lub zog (watts). LED teeb pom kev zoo muaj ntau dua luminous efficiency thaum piv rau lwm yam teeb pom kev zoo technologies. Thaum yuav cov teeb pom kev zoo cov neeg siv khoom yuav tsum tau them nyiaj ntau dua rau qhov ua tau zoo luminous piv txwv li tus nqi ntawm lub teeb lub teeb tsim ib watt tshaj qhov tseeb wattage ntawm lub teeb. Teeb nrog ntau dua lumens ib watt muaj kev ua haujlwm zoo dua. Daim duab 1 qhia txog kev sib piv ntawm cov teeb pom kev zoo sib txawv.
