LED (Lub Teeb Emitting Diode) efficiency yog qhov tseem ceeb hauv kev txiav txim siab qhov zoo ntawm LED teeb pom kev zoo. Hauv cov ntsiab lus yooj yim, LED efficiency yog hais txog tus nqi ntawm lub teeb tsim ib chav tsev ntawm cov khoom siv hluav taws xob. Kev suav cov kev ua haujlwm ntawm LED muaj ntau yam xws li kev ua haujlwm luminous, lub zog nkag, thiab lub teeb tso zis.
Thawj kauj ruam los xam cov kev ua haujlwm ntawm LED yog los txiav txim siab qhov ua tau zoo ntawm LEDs. Qhov no yog qhov ntsuas ntawm qhov teeb pom kev zoo npaum li cas los ntawm LED txheeb ze rau lub zog siv los tsim nws. Luminous efficiency yog ntsuas nyob rau hauv lumens ib watt (lm / W). Feem ntau, cov LEDs zoo tshaj plaws muaj qhov ua tau zoo ntawm ntau dua 100 lm / W, uas txhais tau hais tias lawv tsim ntau dua 100 lumens ntawm lub teeb rau txhua watt ntawm cov khoom siv hluav taws xob.
Lwm qhov yuav tsum tau xav txog yog lub zog nkag. Lub zog hluav taws xob yog lub zog xav tau los ua haujlwm ntawm LED. Qhov no tuaj yeem ntsuas hauv Watts. Hauv ntau qhov xwm txheej, cov tuam txhab LED qhia qhov siab tshaj plaws ntawm lub zog nkag rau ib qho LED.
Thaum kawg, lub teeb tso zis yog qhov tseem ceeb hauv kev txiav txim siab qhov ua tau zoo ntawm LED. Lub teeb tso zis ntawm LED yog ntsuas hauv lumens, uas yog ntsuas qhov ntsuas ntawm lub teeb tsim los ntawm LED. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub teeb tso zis tuaj yeem sib txawv nyob ntawm lub teeb faib thiab xim kub ntawm LED.
Txhawm rau xam cov LED efficiency, cov qauv hauv qab no tuaj yeem siv:
LED efficiency=tso zis teeb (lumens) / input zog (Watts)
Piv txwv li, yog tias ib qho LED tsim 120 lumens ntawm lub zog input ntawm 1 Watt, LED efficiency yuav xam raws li nram no:
LED efficiency=120 lumens / 1 Watt=120 lm / W
Yog li ntawd, qhov ua tau zoo ntawm LED yog 120 lm / W, uas qhia tau hais tias LED muaj txiaj ntsig zoo ntawm kev tsim lub teeb txheeb ze rau lub zog tawm tswv yim.
Hauv kev xaus, suav cov kev ua haujlwm ntawm LED yog qhov tseem ceeb rau kev ua kom ntseeg tau tias LED teeb pom kev zoo yog lub zog txuag thiab ua haujlwm zoo. Los ntawm kev xav txog qhov ua tau zoo ntawm lub teeb ci, lub zog hluav taws xob, thiab lub teeb tso zis, peb tuaj yeem txiav txim siab qhov ua tau zoo ntawm LED. Thaum kawg, qhov no yuav ua rau kev txuag nqi thiab txiaj ntsig ib puag ncig.
