Indlela yokusebenzisa i-multimeter ukukhangela i-LED Bead eyonakeleyo?
I-LED yokukhanyisa i-bead ihlala ithatha uchungechunge kunye noqhagamshelwano oluhambelanayo. Xa isibane sesibane se-LED sonakalisiwe, uphawu oluqhelekileyo lwesiphoso kukuba ukukhanya akwanele. Kwizibane zesibane se-LED ezonakalisiweyo kuthotho kunye nemigca ehambelanayo, ezi ndlela zilandelayo zingasetyenziselwa ukufumanisa.
Ukugweba ukuba ilungile okanye imbi:
(1) Ukufumanisa i-multimeter kunye nendlela yokugweba. Ekubeni i-bead yesibane se-LED ineempawu ze-diode, inokufunyanwa okanye igwetywe ngokusebenzisa ibhloko ye-digital multimeter diode okanye i-pointer yohlobo lwe-multimeter R × 1 ibhloko endleleni okanye isiphaluka esivulekileyo. Ukuba akukho ngxaki nge-bead yesibane se-LED, i-bead yesibane se-LED iya kukhanya xa ibhaqa. Ukuba i-bead yesibane se-LED efunyenweyo ayinayo iimpawu ze-diode kwaye ayiyi kukhupha ukukhanya kweenkwenkwezi, kuya kugwetywa ukuba yonakaliswe.
(2) Indlela yokugweba efanayo. Kwezinye iintsimbi ze-LED ezigugayo, ukusetyenziswa kokuchongwa kwe-multimeter kunokubona ukukhanya kweenkwenkwezi ezincinci, kodwa akukho kukhanya okwaneleyo emva kokukhanyisa. Kule nkalo, indlela ehambelanayo ingasetyenziselwa ukufumana ubuhlalu besibane se-LED esiguga. Thatha ibhalbhu ye-3W njengomzekelo. Indlela ethile yile ilandelayo.
(3) Indlela yokuzimisela ngokuhambelana kwe-LED. Ukusebenzisa i-LED ye-1W esebenza kakuhle, isikhonkwane ngasinye sithengiswa ngocingo olufutshane njengesibane sokubona, kwaye sisetyenziselwa ukujikeleza i-bead yesibane ngasinye se-LED kwibhalbhu. Nje ukuba ibe mfutshane ibe liliso lesibane se-LED, i-3W Ukuqaqamba kwebhalbhu kuya kwanda kakhulu, kwaye ibhalbhu ye-LED efinyeziweyo liso le-LED eligugayo. Emva kokutshintsha entsha, impazamo inokupheliswa.
(4) Indlela yokunciphisa ucingo. Ukuba akukho LED ilunge ngolo hlobo okwangoku, ungasebenzisa iziphelo ezimfutshane zocingo olufutshane ukujikeleza ibhalbhu nganye ye-LED kwibhalbhu. Nje ukuba ibe mfutshane kwibhalbhu ethile ye-LED, ukuqaqamba kwebhalbhu ye-3W kuya kwanda kakhulu. Isibane sesibane se-LED esifutshane sisibane sesibane se-LED esigugayo. Emva kokutshintsha entsha, impazamo inokupheliswa. Ukuba akukho nto entsha yokutshintsha ngexesha, unokuphinda ujikeleze i-bead yesibane se-LED egugayo kuzo zombini iziphelo. Nje ukuba uthenge i-accessory entsha, kufuneka uyibuyisele kwangethuba.
