Diode yotchuka yotulutsa kuwala imatsikira ku 1.6V-2.1V, ndi mawonekedwe apano a 5-20mA LED 1. Tanthauzo la malire (1) Lonjezani kugwiritsa ntchito mphamvu PM: kulonjeza kuwonjezera mitu iwiri ya magetsi a LED ku DC Voltage yamagetsi yakale kwambiri usiku womwe umadutsamo. Wolokani mtengo uwu, kutentha kwa LED ndi kuwonongeka. (2) Positive DC panopa IFM: Dongosolo lofunika kwambiri la databst panopa lolonjezedwa. Mtengo uwu ukhoza kuwononga diode. (3) Reverse voltage VRM: Magetsi akale kwambiri omwe adalonjeza kuwonjezera. Ndi mtengo uwu, diode yotulutsa kuwala imatha kusweka ndikuwonongeka. (4) TOPM: Sikelo ya kutentha kwa diode yotulutsa kuwala imatha kugwira ntchito bwino. Pansi kapena apamwamba kuposa kutentha, kuwala -emitting diode sizigwira ntchito bwino, ndi zotsatira za anakana. 2. Kufunika kwa magawo amagetsi (1) Kuchita bwino pakali pano IF: Ikutanthauza mtengo wapano wa kuwala kowoneka bwino kwa diode pakuyaka kwa diode. Pogwiritsira ntchito kwenikweni, muyenera kusankha ngati mukufuna kusankha ngati mukufuna ·Pansi ifm. (2) VF yabwino yogwira ntchito: Mphamvu yogwira ntchito yoperekedwa patebulo la parameter imapezeka pansi pa kutsogolo kwapano. Nthawi zambiri amayezedwa ngati IF = 20mA. Diode yowala ili pamagetsi opangira VF pa 1.4 3V. Kutentha kwakunja kukakwera, VF idzatera. (3) Mbali ya V-I: Pamene ubale wapakati pa voteji ndi wapano wa diode yotulutsa kuwala uli wocheperapo mtengo wina (wotchedwa khomo), wapano ndi wochepa kwambiri ndipo samatulutsa kuwala. Mphamvu yamagetsi ikafika pamtengo wina, kutsogolo kwapano kumakhala kosavuta komanso kowala. Momwe mungachotsere nditha kuchotsa ma voliyumu abwino a chubu chowunikira, chosinthira chapano komanso voteji yam'mbuyo ya chitoliro chowala kuchokera momwe mungachotsere mkanda wa V-LED. Positive luminous pipe reverse leakage panopa IR
