Ua ntej, peb yuav tsum paub tias LED sawb teeb yog cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob.Koj tsis tuaj yeem txuas ncaj qha rau AC110V lossis AC220V.Qhov ntawd yuav ua rau lub teeb ci LED puas thiab cia koj cov cuab yeej ntes hluav taws.Koj yuav tsum siv lub zog coj mus rau qhov tso zis. DC12V lossis DC24V.
Lwm qhov yuav tsum tau saib xyuas yog polarities. Muaj ob hom ncej: qhov zoo (ntxiv) thiab qhov tsis zoo (-). Koj yuav tsum xyuas kom meej tias LED sawb teeb pom kev zoo txuas rau tus tsav tsheb yog qhov zoo thiab qhov kev sib txuas tsis zoo rau tus tsav tsheb yog qhov tsis zoo. Kev xaim tsis raug yuav tsis cia koj lub teeb pom kev zoo.
