LED Digital Tube Performance Indlela elula yokuFumana Intshayelelo

Umatshini wetyhubhu yedijithali ye-LED unokubona nje ukungahlonelwa kwetyhubhu yedijithali ye-LED. Iimfuno ezingafanelekanga zetyhubhu yedijithali ye-LED zifuna umyinge wombala, akukho kutshintsha kwebala kunye namaqamza omoya. Ngaphantsi kwesiseko se-amateur, inokusetyenziswa njengovavanyo olongezelelweyo. I-electrode engafanelekanga yeebhetri ezi-3 ze-volt ezomisiweyo zigxininiswe kwizinto ezigqithisileyo zoluntu ze-tube yedijithali ye-LED. Xa lo mgca uchukumisa ukugqithiswa okulungileyo kwe-stroke ethile, eso sohlwayo kufuneka siboniswe. Ngale ndlela ilula, unokujonga ukuba ityhubhu yedijithali inepeni eyaphukileyo (i-stroke ethile ayinakuboniswa), nokuba ipeni (ezinye izibetho ziqhagamshelwe kwindlela), kwaye inokuthelekiswa nokuqina kunye nobuthathaka bendlela. imivimbo eyohlukeneyo. Ukuba unako ukukhangela i-co -anode ityhubhu yedijithali, kufuneka utshintshe kuphela ibhetri echanekileyo kunye nezibonda ezimbi ukutshintsha umgca. Indlela iyafana nale ingasentla. LED ityhubhu yedijithali Nganye imivumbo ukusebenza ILED yangoku imalunga 5 —Phakathi kwe-10mA, ukuba i-current iya kutshabalalisa ityhubhu yedijithali ngexesha loNyaka omtsha, kuyimfuneko ukwandisa ukuchasana kokuhamba. Ixabiso lokuchasa lingabalwa ngokwefomula: ixabiso le-R = (u —I-ULED) / ILED Imoto ifakwe kunye ne-LED yesibane se-U ukongeza i-voltage yentloko ezimbini ze-LED, kunye ne-ULED yi-LED ye-digital tube ye-voltage nganye (malunga ne-2 volts). Iziseko ze-HFE ezisebenzisa iimitha zedijithali zendalo iphela zinokujonga ngokulula indawo ekhanyayo yeetyhubhu zedijithali ze-LED. Xa ukhetha i-NPN gear, umngxuma u-C ulungile, kwaye i-moonhole ayinayo. Umzekelo, xa ujonga i-LTS547R -uhlobo co -cathode LED ityhubhu yedijithali, faka i-single -stock eneenkcukacha zesikhokelo socingo olusuka kwi-Eh hole, kwaye ucingo lukhokelela ekupheleni kwe-9 pole (unyawo kunye nonyawo lwesibini ludityaniswe ngaphakathi, luyakwazi khetha enye njenge?); I-C -hole ikhokelela ucingo ukuba uqhagamshelane ne-electrodes yecandelo ngalinye ngokulandelelana, elinokuthi lihlulwe kwimivimbo ehambelanayo.
