Ujongwa njani iFault of the Light-emitting Diode Lamp Bead

Sesiphi isizathu sokuba amaso esibane angakhanyiswa kwibhodi yesekethe? Ujongwa njani? Okokuqala, khangela ukuba isiphaluka sisetyenziswe ngokuqhelekileyo, kwaye wenze uhlalutyo oluthile olusekelwe kwisekethe ethile. Nangona kunjalo, uninzi lwezizathu kukuba ii-LED zafumana ngengozi i-polarity elungileyo kunye nengalunganga ye-LED ngexesha lofakelo okanye inkqubo ye-welding ngaphambi kokufakwa. I-welding yokwenene ayinamandla), i-welding ye-virtual sesona sizathu sokusilela, ngakumbi kubaqalayo abangenamava e-welding. Le ngxaki inokwenzeka kakhulu. Kungenzeka kwakhona ukuba ukuvuza kwentsimbi yombane kubangela ukuba i-LED iphumelele isekethe emfutshane. Kukho inxalenye yecandelo lesekethe yokuqhuba ukudibanisa okanye i-weld kakuhle, kwaye ezinye iisekethe zinokuthi kwakhona ixabiso lecandelo lohlengahlengiso alilungiswanga kakuhle. Ngaphambi kokuba isiphaluka sifakwe, jonga isheke kwaye uhlolisise ngenyameko phambi kombane. Ukuba ukukhanya akuvulwanga, amandla kufuneka acinywe ngokukhawuleza, kwaye kufuneka kwenziwe ukuhlolwa. Awukwazi ukunkqonkqoza kwibhodi yesekethe ukuzama ukufumana impazamo. ngele ndlela. Ukuba isiphaluka esine-filter capacitor, okokuqala, kufuneka usebenzise i-screwdriver okanye ucingo ukukhupha iinyawo ezimbini ze-filter capacitor ngaphambi kokuyijonga. Eli nyathelo libaluleke kakhulu! Ngenxa yokuba i-capacitor ye-filter ine-voltage ephezulu engaphezulu kwe-1.4 kumaxesha ombane ombane (ngaphezu kwe-1.4 amaxesha ombane wokubonelela ngombane (Umzekelo, xa umbane we-220V unokuphakama njenge-310V), ukuze ungonakalisi umzimba womntu. okanye utshabalalise i-LED xa i-capacitance isindile kwi-capacitor okanye ngethuba isekethe iqhagamshelwe! LED nganye. Nika ingqalelo kwi-polarity yamandla ebhetri njenge-polarity ye-LED, ukuze usebenzise i-polarity ye-LED, ukuze ujonge ukuba i-LED nganye inokukhanya. Ukuhlolwa kwesekethe yokuqhuba, kufuneka uhlolisise ngenyameko ukuba ngaba isiphaluka siphosakele ngokomzobo wesiphaluka. Nika ingqalelo ekhethekileyo ukujonga ibhulorho yokulungisa (unyawo olude luphuma kwi-electrode elungileyo, idiagonal yimveliso ye-electrode engalunganga, ezinye iinyawo ezimbini ziyigalelo le-AC) okanye i-diode yokuhlaziya, kunye nombhobho we-voltage diode wombane Nokuba i-polarity ichanekile. (isiphelo esinye esinomgca omnyama okanye omhlophe sibi), kwaye khangela ukuba i-electrode ezintathu ze-crystal triode okanye i-voltage edibeneyo yesiphaluka ayilungile. Kulungile, ingcaciso ye-diode ekhanyayo ilapha,
