Ungayisebenzisa kanjani i-multimeter ukuthola i-LED Bead eyonakele?
Ubuhlalu obukhanyayo be-LED ngokuvamile buthatha uchungechunge noxhumano oluhambisanayo. Lapho ubuhlalu besibani se-LED bonakalisiwe, isici esivamile sephutha ukuthi ukukhanya akwanele. Ngobuhlalu besibani se-LED abalimele ochungechungeni kanye nemigqa ehambisanayo, izindlela ezilandelayo ngokuvamile zingasetshenziswa ukuthola.
Ukwahlulela ukuthi kuhle noma kubi:
(1) Ukutholwa kwamamitha amaningi kanye nendlela yokwahlulela. Njengoba ubuhlalu besibani se-LED bunezici ze-diode, ingatholwa noma yahlulelwe ngokusebenzisa i-digital multimeter diode block noma i-pointer yohlobo lwe-multimeter R × 1 block emgwaqeni noma isifunda esivulekile. Uma ingekho inkinga ngobuhlalu besibani se-LED, ubuhlalu besibani se-LED buzokhanya uma bububona. Uma ubuhlalu besibani se-LED obutholiwe bungenazo izici ze-diode futhi ngeke bukhiphe ukukhanya kwenkanyezi okuncane, kuzogwetshwa njengokulimala.
(2) Indlela yokwahlulela efanayo. Kobunye ubuhlalu besibani se-LED esigugayo, ukusetshenziswa kokutholwa kwamamitha amaningi kuvame ukubona ukukhanya kwenkanyezi encane, kodwa nokho akukho ukukhanya okwanele ngemva kokukhanyisa. Kulokhu, indlela ehambisanayo ingasetshenziswa ukuthola ubuhlalu besibani se-LED esiguga. Thatha isibani se-3W njengesibonelo. Indlela eqondile imi kanje.
(3) Indlela yokunquma ehambisanayo ye-LED. Kusetshenziswa i-LED engu-1W esebenza kahle, iphinikhodi ngayinye idayiswa ngocingo olufushane njengesibani sokubona, bese isetshenziselwa ukuzungeza ubuhlalu besibani ngasinye se-LED kusibani. Uma isifushanisiwe ibe ubuhlalu besibani se-LED, i-3W Ukukhanya kwe-bulb kuzokhula kakhulu, kanti isibani se-LED esifushane siwuhlalu lwesibani se-LED esiguga. Ngemva kokufaka esikhundleni esisha, iphutha lingaqedwa.
(4) Indlela yokunqamulela ucingo. Uma ingekho i-LED enhle kangaka okwamanje, ungasebenzisa iziphetho ezimfishane zocingo olufushane ukuze ufinyeze isibani ngasinye se-LED kusibani. Uma isifushanisiwe ibe isibani esithile se-LED, ukukhanya kwe-3W kuzokwanda kakhulu. Ubuhlalu besibani se-LED obufushanisiwe ubuhlalu besibani se-LED esiguga. Ngemva kokufaka esikhundleni esisha, iphutha lingaqedwa. Uma singekho isisekeli esisha ongasishintsha ngesikhathi, ungakwazi futhi ukusheshisa ubuhlalu belambu le-LED eligugayo emikhawulweni yomibili. Uma usuthenge insiza entsha, kufanele uyishintshe kusenesikhathi.
