LED Digital Tube Performance Mokhoa o bonolo oa ho lemoha Mokhoa Kenyelletso

Mochini oa li-tube tsa dijithale tsa LED o khona ho bona feela ho se hlomphehe ha tube ea dijithale ea LED. Litlhoko tse sa hlompheheng tsa tube ea dijithale ea LED li hloka karolelano ea mebala, ha ho na mebala ea lehae le lipudula tsa moea. Tlas'a motheo oa bo-amateur, e ka sebelisoa e le tlhahlobo e tsoelang pele. Electrode e mpe ea libeteri tse omisitsoeng tsa 3 volt e tsepamisitsoe ho maemo a fosahetseng a sechaba a tube ea dijithale ea LED. Ha mola ona o ama mekhoa e metle e feteletseng ea stroke se itseng, setorouku seo se lokela ho bontšoa. Ka tsela ena e bonolo, o ka hlahloba hore na tube ea digital e na le pene e robehileng (setoro se itseng se ke ke sa bontšoa), esita le pene (liropo tse ling li amana le tsela), 'me li ka bapisoa le matla le bofokoli ba matla. mefuta e mengata e fapaneng. Haeba o ka hlahloba co -anode digital tube, o hloka feela ho fetola lipalo tse ntle le tse mpe tsa betri ho fetola mohala. Mokhoa o tšoana le o ka holimo. LED digital tube E 'ngoe le e 'ngoe lichapo li sebetsa hona joale ILED e mabapi le 5 —Pakeng tsa 10mA, haeba hona joale e tla senya tube ea digital nakong ea Selemo se Secha, ho hlokahala ho eketsa ho hanyetsa ho phalla. Boleng ba khanyetso bo ka baloa ho latela foromo: R value = (u —ULED)/ILED Koloi e kentsoe ka lebone la lebone la LED U ho eketsa motlakase oa lihlooho tse peli tsa LED, 'me ULED ke tube ea LED ea digital bakeng sa motlakase o mong le o mong (hoo e ka bang 2 volts). Li-sockets tsa HFE tse sebetsanang le limithara tsa universal tsa dijithale li ka lekola tikoloho e khanyang ea li-tubes tsa dijithale tsa LED. Ha u khetha lisebelisoa tsa NPN, lesoba la C le nepahetse, 'me khoeli e mpe. Ka mohlala, ha u hlahloba LTS547R -type co -cathode LED digital tube, kenya terata e le 'ngoe -stock e qaqileng ea tataiso e tsoang ho Eh hole,' me mohala o lebisa qetellong ea 9 pole (leoto le leoto la bobeli li kopantsoe ka hare, li ka khetha e le 'ngoe joalo ka?); C -hole e lebisa terata ho ikopanya le li-electrode tsa karolo ka 'ngoe ka tatellano, e ka arohanngoa le lichapo tse lumellanang.
