Kufuneka ugcinwe njani umboniso we-LED wegumbi lenkomfa?

Jonga ukuba iintambo zombane kunye neplagi yamandla yemodyuli yokuqala enophawu lokuqhelaniswa nophawu lwedatha engaqhelekanga ikunxibelelwano oluhle. Iimodyuli ezininzi azikwazi ukukhanyiswa rhoqo okanye aziqhelekanga. Ingatshintshwa ukuba imodyuli ekhokelwayo ayikwazi ukukhanyisa, ebonisa ukuba akukho igalelo lamandla okutshintsha. Qhagamshelana nesebe lonikezelo lwamandla okanye usebenzise i-digital multimeter yokuqinisekisa.

Ukuba imodyuli enye ayikhanyi, khangela ukuba umbane wayo wokutshintsha usebenza ngokufanelekileyo. Ukuba ngaphezulu kwemodyuli enye ibonisa ukuphazamiseka kombala kunye nokungahambelani, oku kunokuba ngenxa yoqhagamshelwano olubi lwekholamu yokuhanjiswa kwedatha. Okulandelayo, jonga ukuba iplagi yamandla yemodyuli ikhululekile. Ukutshintsha umgca wekholomu ovavanyiweyo, tsala kwaye uphinde ufake umgca. Ungaphanda ukuba ngaba kukho umba ngePCB isinxibelelanisi sebhodi ukuba kukho umba xa utshintsha umgca wentambo yentambo elungileyo.

Indlela yokuqinisekisa ukuba isibane esisodwa sicinyiwe: Ukuqinisekisa ukuba igumbi lenkomfa leleUmboniso we-LEDyaphukile, sebenzisa isixhobo. Ukuba isibane saphukile, yibuyisele ngokulandela inyathelo lesihlanu elidweliswe ngezantsi. Ubuchule bokwenyani bokulinganisa izibane kukusebenzisa i-digital multimeter kwi-resistor X1 inxalenye, ukudibanisa inqanaba le-led elungileyo kwi-digital multimeter's iammeter emnyama ye-DC, kwaye uqhagamshele inqanaba elibi kwi-ammeter ye-DC ebomvu. Ibhalbhu efakwe ngokuchanekileyo iya kusebenza ukuba ilayidi ilayitiwe. ukuba isibane silayitiwe Ayikokukhanya kugqwesileyo kumlinganiselo ochanekileyo ukuba sicinyiwe.

I-LED engaphantsi kwesondlo (indawo engalawulekiyo): Ngokusekelwe kwiinkcukacha, khetha enye yezi ndlela zilandelayo zokulondoloza ukuvavanya imeko ye-led ngexesha loviwo lwesibane esisodwa. Ukugcina ubuso bucocekile: Isikhuselo sobuso sinokukhutshwa ngesikrudrayiva esihambelanayo. Buyisela imaski yokukhusela kwaye ubuyisele isibane. Ingqungquthela yokuqalaigumbi le-LED elibonisa isikriniibuyiselwa xa ukukhanya kutshintshile kwaye isisombululo se-colloidal sitywinwe. Ukwenza ulondolozo, qinisa isikrufu ngasemva. Ukwenza oku, vula i-screw kwicala elingasemva ukuze uqhawule iplagi yamandla kunye nekhebula lophawu lwedatha, susa ngokungaziyo imodyuli ukusuka kumngxunya wentsimbi, kwaye emva koko uye kwicala elingasemva le-chassis ephambili. ubuchule bokugcina ubuso.
