Ua ntej tshaj plaws, ua tsaug rau koj txoj kev mloog thiab muab qhov tseem ceeb rau tsab xov xwm no, thiab tos ntsoov rau koj nyeem ntxiv. Hauv cov ntsiab lus hauv qab no, peb yuav muab ntau yam kev paub txog cov khoom siv teeb pom kev zoo rau koj, yog li thov koj nyob twj ywm.
Thaum xaiv lub teeb LED, peb yuav xub mloog zoo rau ntau yam xws li lub zog, lumen, xim kub, qib dej tsis nkag, cua sov tawm, khoom siv thiab lwm yam. Los yog los ntawm kev sab laj cov khoom lag luam, mus saib cov vev xaib, siv Google tshawb nrhiav, saib YouTube cov yeeb yaj kiab lossis los ntawm lwm txoj hauv kev los nrhiav cov khoom lag luam zoo. qhov tseeb, nws yog qhov tseem ceeb rau cov neeg siv xa mus rau cov yam no hauv lawv txoj kev txiav txim siab. Tab sis, koj puas paub PF tus nqi yog dab tsi?
Ua ntej, tus nqi PF (power factor) ua tus power factor, tus nqi PF sawv cev rau cosine ntawm qhov sib txawv ntawm theem ntawm qhov input voltage thiab input tam sim no. Tus nqi no cuam tshuam ncaj qha rau kev siv hluav taws xob zoo.
Cov xwm txheej hauv qab no yog ob qho:
Rau lub teeb LED uas muaj tus nqi PF qis, lub zog hluav taws xob yuav raug hloov mus ua lub zog cua sov thiab lwm yam zog thaum lub sijhawm ua haujlwm. Ib feem ntawm lub zog hluav taws xob tsis tuaj yeem siv tau zoo thiab raug pov tseg.
Lwm qhov xwm txheej yog siv lub teeb LED PF siab. Thaum nws pib, nws yuav hloov lub zog hluav taws xob mus rau hauv lub zog teeb, yog li txuag kev siv hluav taws xob thiab txo cov khib nyiab hluav taws xob.
Tus nqi PF feem ntau suav tias yog ib qho tseem ceeb rau kev ntsuam xyuas kev ua haujlwm ntawm lub teeb LED. Yog li ntawd, peb xav kom koj ua tib zoo saib thiab sib piv cov nqi PF ntawm ntau hom thiab qauv thaum xaiv lub teeb LED. Yog li ntawd, tus nqi PF siab dua, kev siv hluav taws xob zoo dua, thiab qhov cuam tshuam rau ib puag ncig yuav raug txo qis raws li.
Zuag qhia tag nrho, tus nqi PF yog ib qho tseem ceeb thiab muaj tus nqi siv tau zoo rau kev siv hluav taws xob zoo. Yog li ntawd, thaum xaiv lub teeb LED, nws raug pom zoo kom xav txog cov yam xws li lub zog, lumens, xim kub, kev ua haujlwm tsis muaj dej, lub peev xwm ua kom sov, cov khoom siv, thiab lwm yam, thiab xyuam xim rau tus nqi siv tau ntawm tus nqi PF.
