Ob qhov tseem ceeb ntawm kev coj cov teeb roj fluorescent uas yuav tsum paub
1. Lub zog muaj zog (PF): Lub zog muaj txiaj ntsig yog tus nqi cosine ntawm theem sib txawv ntawm qhov hluav taws xob thiab tam sim no. Vim tias ob qho tam sim no thiab qhov hluav taws xob yog cov duab yoj, ib qho yog kab sine thiab lwm qhov yog daim duab cosine; vim tias ob daim duab kab duab sib txawv ntawm 1/4 lub sijhawm (piv txwv li: 90 degrees), tus nqi PF tau tsim. Txhawm rau txhawm rau nce tus nqi PF, nws yog qhov tsim nyog Kev hloov kho hluav taws xob tau ntxiv rau cov khoom siv hluav taws xob, yog li tus nqi ntawm cov khoom siv hluav taws xob nrog tus nqi PF siab yog qhov siab. Tus nqi PF yam tsis muaj PF hloov kho Circuit yog feem ntau nyob ib puag ncig 0.6, thiab PF tus nqi nrog PF Circuit tuaj yeem pib mus txog ib puag ncig 0.9 lossis siab dua.
Thaum PF tus nqi qis, nws yuav ua paug lub zog hluav taws xob ntawm tag nrho cov khoom siv hluav taws xob. Thaum PF tus nqi qis, kev siv hluav taws xob tsim los ntawm cov cuab yeej siv hluav taws xob ntawm kab sib chaws tau qis dua. Yog li ntawd, lub tebchaws muaj PF tus nqi xav tau rau qee yam khoom siv hluav taws xob muaj zog. Rau cov uas qis dua 50W, tsis muaj qhov xav tau meej. Lub tebchaws xav tau yog tias PF tus nqi ntau dua 0.6.
2. Kev hloov pauv kev ua tau zoo: Feem ntau hais lus, nws yog qhov sib piv ntawm lub zog tso tawm rau lub zog tawm tswv yim. Piv txwv li, 10W ntawm lub zog hluav taws xob tau siv los ntawm lub raj teeb, tab sis tsuas yog 8W ntawm lub zog hluav taws xob tau siv los tso lub teeb (tseem hu ua kev ua haujlwm zoo). Yog tias 2W lub zog hluav taws xob poob vim cua sov ntawm lub tshuab hluav taws xob (tseem hu ua: tsis ua haujlwm), tom qab ntawd lub zog hloov pauv tau zoo ntawm lub teeb no yog 80%.
