Luminous Diode Technical Parameter Tsananguro

Yakakurumbira mwenje emitting diode inodonha kusvika 1.6V-2.1V, uye hunhu hwekushanda ikozvino kwe5-20mA LED 1. Zvinorehwa nemuganhu paramende (1) Vimbiso kushandisa simba PM: vimbisa kuwedzera misoro miviri yeLED kuDC voltage voltage Hukoshi hwehusiku hwekare hunoyerera nemairi. Yambuka kukosha uku, LED fever uye kuparadzwa. (2) Positive DC ikozvino IFM: Iyo inonyanya kukosha databst ikozvino yakavimbiswa. Kukosha uku kunogona kuparadza diode. (3) Reverse voltage VRM: Iyo yekare reverse voltage yakavimbiswa kuwedzera. Nekukosha uku, iyo light emitting diode inogona kuputswa uye kuparadzwa. (4) TOPM: Chiyero chekushisa chechiedza-emitting diode chinogona kushanda zvakajairwa. Pazasi kana kupfuura tembiricha iyi, iyo light-emitting diode haishande nemazvo, uye mhedzisiro yekuramba. 2. Kukosha kwemagetsi parameters (1) Positive working current IF: Inoreva kukosha kwazvino kweyakajairika kupenya kweiyo diode kana ichipenya diode. Mukushandisa chaiko, iwe unofanirwa kusarudza kana iwe uchida kusarudza kana uchida ·Pazasi ifm. (2) Positive working voltage VF: Iyo voltage yekushanda yakapihwa patafura yeparameter inowanikwa pasi peiyo yakapihwa mberi ikozvino. Inowanzoyerwa kana IF = 20mA. Iyo inopenya diode iri pamhepo inoshanda VF pa1.4 3V. Kana kupisa kwekunze kuchikwira, VF ichamhara. (3) V-I chimiro: Kana hukama pakati pemagetsi uye ikozvino yechiedza-emitting diode ishoma pane imwe kukosha (inonzi chikumbaridzo), ikozvino idiki zvakanyanya uye haibudisi chiedza. Kana iyo voltage ichipfuura imwe kukosha, iyo yekumberi ikozvino inomhanya ine voltage uye inopenya. Nzira yekubvisa sei ini ndinogona kubvisa iyo yakanaka voltage yechiedza chubhu, reverse ikozvino uye reverse voltage yepombi yemwenje kubva pakubvisa V-LED rambi bead. Positive luminous pombi reverse leakage ikozvino IR
