Kutanga, iyo nzira yekutsvaga ye LED kuratidza kugadzirisa
1. Pfupi-dunhu rekutsvaga nzira, iyo yakajeka iratidziro inogadzirisa iyo multimeter kune ipfupi-redunhu yekucherechedza block (kazhinji ine alarm alarm, senge chiziviso cheruzhinji kuzivisa kurira kwesikina, kuona kana paine pfupi redunhu chiitiko, uye nekukurumidza mushure mekunge dunhu pfupi rawanikwa, iyo pfupi yedunhu chiitiko zvakare ndiyo yakajairika matambudziko e LED ekuratidza mamodule .Mamwe anogona kuwanikwa nekutsvaga iyo IC pini uye musoro wepini. kutadza kudzivirira kukuvadza iyo multimeter. Iyi nzira ndiyo nzira inowanzo shandiswa, yakapusa uye inoshanda. 90% yematambudziko anogona kuonekwa nenzira iyi.
2. Resistance yekutsvaga nzira, gadzirisa iyo multimeter kune yekupikisa faira, uone kukosha kwekudzivirira kweimwe pfungwa yeyakajairika bhodhi redunhu, uye wozotarisa kana iyo imwecheteyo bvunzo bvunzo yeimwe chete wedunhu bhodhi rakasiyana neyakajairika kuramba kukosha. Kana zvakasiyana, kukura kwedambudziko kwakatemwa.
3. Voltage yekuona nzira, gadzirisa iyo multimeter kune iyo voltage faira, uone iyo voltage pasi pasi pane imwe nhanho yedunhu inofungidzirwa kuve nedambudziko, enzanisa kana yakafanana neyakajairika kukosha, uye nyore kuona chiyero cheiyo dambudziko.
4. Iyo yekudonha kudonhedza nzira yekutsvaga, iyo multimeter inogadziridzwa kune diode voltage kudonhedza yekutsvaga faira, nekuti iyo IC yese inoumbwa nezvakawanda zvakakosha zvikamu zveyuniti, chete miniaturized, saka kana paine yazvino nzira yekufamba pane imwe yeayo mapini, Ikoko richava voltage kudonhedza nepini. Kazhinji, iyo voltage inodonha pane imwechete pini yerudzi rumwe chete rweIC yakafanana. Zvinoenderana nemhepo inodonha kukosha pini, zvinodikanwa kuti zvishande pasi pemamiriro ekuti dunhu rinodzingwa.
Chechipiri, matanho ekutanga ekugadzirisa ekuratidza LED
1. Sarudza rudzi rwebhodhi reHUB rinoshandiswa nemu module kana bhodhi reyuniti, kuitira kuti dudziro yeiyo tambo iwirirane.
2. Zvinoenderana nemhando dzakasiyana dzemamojuru kana euniti mabhodhi, chirongwa chinoenderana chinotumirwa kukadhi rinogashira, uye kuratidzwa kuri pachena kunovimbisa kuti module nebhodhi reuniti zvinoratidzwa pasi pechirongwa chakakodzera, chinova chiitiko chekutsvaga chikonzero yedambudziko. Rudzi rwemamojuru kana bhodhi rechitokisi rinowanzo kudhindwa paPCB.
3.Kucherekedza module kana iyo unit board chiitiko, uye kuona iko kwekutanga kukanganisa. Semuenzaniso, akajairwa xenon mwenje, tambo mapoinzi, madiki makwere, nezvimwe.
4. Kushandisa multimeter kutsvaga dambudziko, kunyanya kushandisa iri pamusoro nzira pfupi-redunhu yekutsvaga kuona pakati pechip uye tsoka yerambi.
5. Tarisa zvakare
