Kufanele sigcinwe kanjani isibonisi se-LED segumbi lenkomfa?

Hlola ukuthi izintambo nepulaki yamandla yemojuli yokuqala enomumo wesignali yedatha engajwayelekile ixhumene kahle yini. Amamojula amaningana awakwazi ukukhanyiswa njalo noma awajwayelekile. Ingashintshwa uma imojuli eholwayo ingakwazi ukukhanya, okubonisa ukuthi akukho okokufaka kwamandla okushintsha. Xhumana nomnyango wokuphakelwa kukagesi noma usebenzise i-multimeter yedijithali ukuze uqinisekise.

Uma imojuli eyodwa ingakhanyi, hlola ukuthi ugesi wayo oshintshwayo usebenza kahle yini. Uma amamojula angaphezu kweyodwa abonisa ukuphazamiseka kombala kanye nokungahambisani, lokhu kungase kube ngenxa yokuxhumana okungekuhle kwekholomu yesignali yedatha. Okulandelayo, bheka ukuthi ipulaki yamandla yemojuli ikhululekile yini. Ukuze ungene esikhundleni somugqa wekholomu ohloliwe, donsa bese uwufaka kabusha umugqa. Ungaphenya ukuthi ingabe ikhona yini inkinga ngesixhumi sebhodi le-PCB uma kuphakama inkinga lapho kushintsha ulayini wekhebula lomugqa omuhle.

Ungenza kanjani isiqiniseko sokuthi isibani esisodwa sivaliwe: Ukunquma ukuthi igumbi lenkomfa ngelakho yiniIsibonisi se-LEDiphukile, sebenzisa insimbi. Uma ukukhanya kwephukile, kushintshe ngokulandela isinyathelo sesihlanu esibhalwe ngezansi. Isu langempela lokulinganisa izibani ukusebenzisa i-multimeter yedijithali engxenyeni engu-X1 ephikisayo, ukuxhumanisa isiteji se-led ephozithivu ye-ammeter ye-DC emnyama ye-multimeter, bese uxhuma isiteji esinegethivu ku-ammeter ye-DC ebomvu. I-bulb elinganiswe kahle izosebenza uma i-led ivuliwe. uma ukukhanya kukhanyisiwe Akukona ukukhanya okuhle kakhulu kokulinganisa okunembile uma kuvaliwe.

I-LED engaphansi kwesondlo (iphoyinti elingalawuleki): Ngokusekelwe emininingwaneni, khetha enye yamasu alandelayo okulungisa ukuze uhlole isimo seledi ngesikhathi sokuhlolwa kwelambu elilodwa. Ukugcina ubuso buhlanzekile: Isivikelo sobuso singasuswa ngesikrudrayiva esihambisanayo. Buyisela imaski yokuzivikela bese ubuyisela isibani. Ingqungquthela yokuqalaIsikrini se-LED segumbiibuyiselwa lapho ukukhanya kushintshiwe futhi isisombululo se-colloidal sivaliwe. Ukuze wenze ukunakekelwa, qinisa isikulufu ohlangothini olungemuva. Ukuze wenze lokhu, qaqa isikulufu esisehlangothini elingemuva ukuze unqamule ipulaki yamandla nekhebuli yesignali yedatha, ukhiphe ngokungenhloso imojuli embotsheni yensimbi yeshidi, bese uya ohlangothini olungemuva lwe-chassis eyinhloko. inqubo yokulungisa ubuso.
