Eqinisweni, sonke siyazi ukuthi umkhiqizo obonisa i-LED wasendlini kungakhathaliseki ukuthi ikhwalithi yinhle kangakanani, kukhona ukunakekelwa, ubude bayo bempilo ngaphezu kwekhwalithi yomkhiqizo ngokwawo, ukunakekelwa kuphinde kube ukhiye obalulekile wesibonisi se-LED yasendlini, njenganoma yimuphi omunye. imikhiqizo, kunengqondo ukuba nezinkinga.Esingakwenza ukuthola kangcono izinkinga ngaphambi kokuba bafike bazokwenza umsebenzi wokulungisa kusenesikhathi ngangokunokwenzeka.Ngakho-ke yiziphi izindlela zokulondolozwa nezindlela zokutholwa kwesikrini sokubonisa se-LED sasendlini?Umsebenzisi kufanele enze kanjani umsebenzi omuhle wokutholwa kwesikrini sesibonisi se-LED sasendlini?
1. Ukuhlolwa kokumelana kwesikrini se-LED yangaphakathi, indlela yokuhlola ukumelana yesibonisi se-LED esingaphakathi endlini, sidinga ukuthumela i-multimeter ekuphikiseni, siqale sithole olunye ucezu lwebhodi lesifunda elivamile ekumelaneni nomhlabathi kwephuzu elithile, bese sibona iphuzu elifanayo ukuhlola enye ingxenye. webhodi lesifunda elifanayo, uma kukhona okuhlukile ngokumelana okuvamile futhi wazi ukuthi kukhona okuhlukile khona-ke ububanzi benkinga yokubonisa okuholwa kwangaphakathi, okuphambene Kuyoba.
2. Indlela yokutholwa kwe-voltage yesibonisi se-LED yasendlini: ukutholwa kwe-voltage yesibonisi se-LED yasendlini ukulungisa i-multimeter kufayela le-voltage, ukuthola isifunda esisolisayo nesiyinkinga sephoyinti ku-voltage yaphansi, uma kuqhathaniswa neyangaphambili kuvamile, ukuze elula ukunquma inkinga.
3. Indlela yokutholwa kwesifunda esifushane se-LED yasendlini: isibonisi se-LED yasendlini indlela yokuthola isifunda esifushane ukulungisa i-multimeter ibe ibhulokhi yokutholwa kwesifunda esifushane, ukuze ukwazi ukubona ukuthi kukhona yini into yesekethe emfushane.Uma kukhona i-short circuit phenomenon, kufanele ixazululwe ngokushesha.Isimo sesifunda esifushane sesikrini sokubonisa se-LED sasendlini siphinde sibe ukwehluleka kwemojula yesibonisi se-LED yasendlini okuvamile.Ngaphezu kwalokho!Ukutholwa komjikelezo omfushane kufanele kwenziwe lapho isekethe ivaliwe ukuze kugwenywe ukulimala ku-multimeter.
4. Ukuhlolwa kokwehla komfutho oholwa ngaphakathi endlini: ukuhlolwa kokwehla kokucindezela kwesibonisi se-LED ukucindezela i-multimeter edluliselwe ekuhlolweni kokuwa kwe-diode, ngoba isibonisi esine-LED esingaphakathi yonke i-IC yakhiwe izingxenye eziningi zamayunithi, ngakho-ke uma ikuphini inikezwa amandla lapho. izoba khona kumhlahlandlela |ukwehla kwezinyawo.Ngaphansi kwezimo ezijwayelekile, ukwehla kwengcindezi kuphinikhodi ye-IC yemodeli efanayo kuyafana.
Ezindleleni ezimbalwa ezingenhla zokulungisa isibonisi se-L ED sangaphakathi singakugcina engqondweni, ngesikhathi sokutholwa, ukuze sigweme ukulimala kwesibonisi sethu se-LED sangaphakathi, kungase futhi kube kuhle kakhulu ukunweba impilo yesevisi yesibonisi sethu se-LED sasendlini.Ngale ndlela, ayikwazi nje ukwelula isikhathi sayo sokusebenzisa, kodwa futhi yonga ukusetshenziswa kwesabelomali okungadingekile.
