Yuav ua li cas thiaj hloov tau cov tshuaj fluorescent ib txwm thiab cov raj fluorescent nrog cov raj LED
Cov raj LED uas tshwm rau ntawm kev ua lag luam tam sim no yuav tsum txuas ncaj qha rau 220V fais fab mov. Lub hwj chim tswj yog sab hauv lub teeb. Lub raj LED tsis xav tau lub ballast lossis pib.
Txoj kev hloov:
Ncaj qha tshem tawm qhov pib ntawm cov teeb ci teeb ci ib txwm siv, txiav tawm txhua qhov tso tawm thiab cov xov hluav taws xob ntawm lub ballast, thiab tom qab ntawd rub ob lub 200V xov hlau rau hauv lub teeb teeb.
Rub ib qho mus rau lwm qhov kawg txhawm rau txhim kho lub teeb tuav, txuas nws nrog ib qho uas nyuam qhuav txiav tawm, qhwv nws nrog daim kab xev insulating, thiab teeb lub raj LED. Ballast tuaj yeem mus lossis tsis mus,
Xijpeem, tam sim no nws tsis ua haujlwm lawm thiab tsis siv hluav taws xob.
Tab sis qee tus neeg hais tias yog tias lub ballast tsis raug tshem tawm, nws yuav tsis cuam tshuam rau kev ua haujlwm, tab sis nws puas yuav siv hluav taws xob?
1. Nws yuav haus ib feem ntawm cov hluav taws xob, yog tias koj tsis ntshai teeb meem, nws yog qhov zoo dua los tshem cov ballast
2. Yog tias nws yog hluav taws xob ballast, nws yuav tsum tau hloov. Vim tias lub tshuab hluav taws xob kho hluav taws xob yuav tsim hluav taws xob siab, rau cov raj coj, cov hluav taws xob tiv taus tsawg dua 300v, thiab nws yooj yim kom puas.
Txawm hais tias Langte coj teeb tuaj yeem tiv taus qhov hluav taws xob txog li 305v. Rau qhov zoo tib yam inductive ballasts, tom qab tshem tus pib, nws tsis tuaj yeem tsim hluav taws xob siab dua thiab nyab xeeb. Vim
Nyob rau hauv ib txwm muaj zog, ballast tsuas yog sib npaug rau inductor, vim tias nws cov qauv yog nyob rau hauv daim ntawv ntawm inductor. Txawm hais tias nyob rau lossis tawm, qee zaum yuav muaj
Rov qab EMF, qhov hluav taws xob siab txawm tias nws yog volts, nws yuav tsis cuam tshuam rau qhov zoo ntawm cov raj LED. Txawm li cas los xij, thov nco ntsoov tias yog tias nws tsis yog qhov siv hluav taws xob tam sim no, tab sis ib txwm tawm los lossis RC fais fab mov,
Tsis muaj kev lees paub, thiab nws yuav tawg tom qab lub sijhawm luv.
