Txoj kev xaim rau LED hloov hluav taws xob yog raws li hauv qab no:
Txuas rau AC Fais Fab:
Txuas L thiab N kab mus rau 220V AC fais fab mov. Qhov no feem ntau txhais tau tias koj yuav tsum txuas lawv mus rau ib lub qhov hluav taws xob hauv tsev.
Cov xaim hauv av tom qab N kab yog xaiv tau rau kev siv sab hauv tsev, tab sis rau kev nyab xeeb, nws raug nquahu kom txuas nws yog tias ua tau.
Txuas lub LED Sawb:
Lub GND davhlau ya nyob twg yuav tsum tau txuas mus rau qhov tsis zoo davhlau ya nyob twg ntawm koj LED sawb. Cov hlau tsis zoo feem ntau yog xim dub lossis dawb.
Lub 12V davhlau ya nyob twg yuav tsum tau txuas nrog lub davhlau ya nyob twg zoo ntawm koj LED sawb. Cov hlau zoo feem ntau yog xim liab lossis xim av.
Fais fab- ntawm Kev Xeem:
Tom qab txuas cov xov hlau, sim lub zog. Yog tias LED tsis teeb, sim hloov GND thiab 12V xov hlau.
Yog tias nws tseem tsis tau teeb pom kev tom qab hloov pauv, qhov ua rau muaj xws li: lub teeb ci LED puas, lub zog tsis ua haujlwm, lossis qhib Circuit Court.
Kev ceev faj: Ua ntej xaim, xyuas kom lub hwj chim tawm kom tsis txhob muaj hluav taws xob poob. Thaum xaim, nco ntsoov txuas qhov zoo thiab qhov tsis zoo terminals kom raug raws li cov ntawv xov xwm xim kom tsis txhob thim rov qab cov kev sib txuas thiab ua rau lub cuab yeej puas. Yog tias koj tsis paub meej tias yuav ua li cas, nws raug nquahu kom nrhiav kev pab los ntawm tus kws tshaj lij.
