Maitiro ekutarisa Mhosho yeChiedza -emitting Diode Lamp Bead

Ndechipi chikonzero nei marambi asina kuvhenekerwa pabhodhi redunhu? Nzira yekuongorora? Kutanga, tarisa kana dunhu rinoshandiswa zvakajairika, uye wozoita ongororo chaiyo zvichienderana nedunhu chairo. Zvisinei, zvizhinji zvezvikonzero ndezvokuti ma LED akangoerekana agamuchira kodzero uye yakaipa polarity ye LED panguva yekuisa kana welding maitiro asati aiswa. Iyo chaiyo welding haina kusimba), virtual welding ndicho chikonzero chikuru chekutadza, kunyanya kune vatsva vasina ruzivo rwekushongedza. Dambudziko iri rinonyanya kuitika. Zvingave zvakare kuti iyo magetsi iron leakge inokonzeresa iyo LED budiriro pfupi yedunhu. Pane chikamu chechikamu chedunhu rekutyaira kuti ubatanidze kana weld zvakanaka, uye mamwe matunhu anogona zvakare kuve kuti iyo yekugadziridza chikamu kukosha haina kugadziridzwa zvakanaka. Isati yaiswa dunhu, tarisa cheki uye nyatsoongorora pamberi pesimba. Kana chiedza chisina kuvhurwa, simba rinofanira kuvharwa pakarepo, uye ipapo kuongorora kunofanira kuitwa. Iwe haugone kugogodza pabhodhi redunhu kuedza kutsvaga kukanganisa. nenzira iyi. Kana iri dunhu rine sefa capacitor, kutanga kune zvese, iwe unofanirwa zvakare kushandisa screwdriver kana waya kuburitsa tsoka mbiri dzesefa capacitor usati waitarisa. Danho iri rakakosha zvikuru! Nekuti iyo sefa capacitor ine yakakwira voltage inodarika 1.4 nguva yemagetsi emagetsi (kupfuura 1.4 nguva yemagetsi emagetsi emagetsi (Somuenzaniso, kana 220V magetsi anogona kunge akakwira se310V), kuti asakuvadza muviri wemunhu. kana kuparadza LED kana capacitance yasara pa capacitor kana nguva iyo dunhu rakabatana! Tag, tarisa kuti imwe neimwe LED polarity haina kururama, wobva washandisa mabhatiri maviri kubatanidza iyo yakanaka uye yakaipa bipolar magetsi ekubata tsoka mbiri dze imwe neimwe LED. Teerera kune polarity yesimba rebhatiri seye polarity ye LED, kuitira kuti ushandise polarity ye LED, kuti Tarisa uone kana LED yega yega inogona kubatika. Kuongororwa kwedunhu rekutyaira, unofanirwa kunyatsoongorora kana dunhu rakashata maererano nedhiyabhorosi yedunhu. Chengetedza kutarisa bhiriji rekugadziridza (tsoka refu ndiyo yakanaka electrode kubuda, diagonal ndiyo negative electrode kubuda, mamwe tsoka mbiri iAC input) kana rectifier diode, uye voltage voltage diode pombi Ingave polarity iri right. (imwe mugumo ine dema kana chena mutsara haina kunaka), uye tarisa kana matatu maelectrodes ekristaro triode kana voltage integrated circuit haana kururama. Zvakanaka, tsananguro yeinopenya diode iri pano,
