Ua ntej tshaj plaws, koj yuav tsum nkag siab tias muaj ob qhov sib txawv ntawm LED teeb hlaws (hauv kab thiab hom SMD) ntawm koj daim duab. Thaum siv LED teeb hlaws, qhov ntsuas hluav taws xob yuav tsum ua kom zoo ib yam. Ntawd yog, yog tias koj xav pom lawv, tom qab ntawd, Koj yuav tsum paub qhov txawv ob txoj hauv kev:
Hauv kab LED
1. Ncaj ncaj lub teeb LED hlaws (nrog ob tus pin) los ntsuas nrog lub ntsuas ntsuas thoob ntiaj teb. Thaum ob txhais ceg nyob rau, thov sau qhov zoo thiab qhov tsis zoo. Feem ntau, qhov hluav taws xob (VF) siv los ntawm ib lub teeb LED teeb yog 3.0 ~ 3.4v, Tom qab ntawd, thawj zaug txuas cov kab teeb hauv kab hauv kab (qhov anode thiab cathode tau teeb tsa hauv txoj kev no), thiab tom qab ntawd xaiv qhov hluav taws xob ntawm koj lub zog siv hluav taws xob, piv txwv li: koj lub zog tsav hluav taws xob (DC)=12v, tom qab ntawd, hauv txhua 4 lub teeb hlaws dai Sib txuas sib txuas (uas yog, txhua lub teeb hlaws yuav tsum tau tsav los ntawm 3v hluav taws xob) kom pom lub teeb ci LED hlaws;
2. Sab-emitting SMD LEDs feem ntau yuav tsum tau muab muag rau ntawm lub rooj tsav xwm hauv Circuit Court, thiab txoj kev sib txuas kuj tseem zoo ib yam li cov kab txuas ncaj qha thiab txuas kev sib raug zoo kom xaiv kab.
Cov lus ceeb toom: cais qhov tsav tam sim no ntawm LED teeb hlaws dai thaum siv, piv txwv li: SMD5730 ib lub teeb hlaws teeb=0.5w (3.4v*120mA) ib leeg tsav hluav taws xob feem ntau hais txog 3v
