E U Ruta Mokhoa oa ho Khetholla Li-tubes tse Fetisetsoang ka Infrared le ho Receiving ka Infrared

Li-tubes tsa mabone a mabone a infrared le tšupu e amohelang lifaha tsa lebone la infrared LED li bitsoa lifaha tsa lebone tsa infrared LED. Sebopeho sa lifaha tsa lebone la infrared LED se tšoana le sefaha se tloaelehileng sa lebone la LED. Ha u qala ho ikopanya le lifaha tsa lebone la infrared LED, ho thata ho khetholla emitter ea lifaha tsa lebone la infrared LED le tube e amohelang ea lifaha tsa lebone tsa infrared LED. R & Basebeletsi ba D ba boletse hore mokhoa oa kahlolo o ka sebelisoa ho khetholla: ho sebelisa multimeter ho lekanya boitsebiso ho lekanya ho hanyetsa polar ea lifaha tsa lebone la infrared LED ka multimeter ho fumana hore na ke lifaha tsa lebone tsa infrared LED. Etsa qeto ea 1: Nakong ea likhahla tsa lebone la infrared LED, tekanyo ea metering e fokotsehile tlas'a boemo ba mahlaseli a khanyang, ho hanyetsa pele ha tube e fetisitsoeng e nyenyane, ho hanyetsa ka morao ho kholo, 'me pene e ntšo ea tafole e ntle (lithapo tse telele), khanyetso e hokahane le mohanyetsi, 'me mohanyetsi o Monyane (1K —20K) ke tube e fetisang ea lifaha tsa lebone la infrared LED. Khanyetso e kholo le e ka morao ke tube e amohelang lifaha tsa lebone la infrared LED. Kahlolo ea 2: Ha tafole e ntšo e hokahane le palo e mpe ke khanyetso e kholo ea lifaha tsa lebone la infrared LED. Ha khanyetso e le nyane 'me ponts'o ea methara e meraro e fetoha ka khanya le bofokoli ba lebone, sesupo se sunya sefaha se amohelang lebone la infrared LED. Kahlolo ea tlhahlobo ea matla a matla a lifaha tsa lebone la infrared Re ka sebelisa pele sefaha sa lebone sa LED le —Khanyetso ena le lifaha tsa lebone tsa lebone la infrared tsa LED li hokahane ka letoto, 'me sefaha sa lebone sa LED se sebelisoa ho bonts'a boemo ba ts'ebetso ba tube ea infrared tube. Sebelisa remote control (DVD remote control, joalo-joalo) ho tobetsa konopo efe kapa efe ea remote ho tube ea tlhahlobo. Ha LED e khanya, tube ke tube e amohelang lifaha tsa lebone tsa infrared LED. Haeba e sa khanye, ke tube e fetisang ea lebone la lebone la infrared LED. Lekanya matla a hona joale a matla a sebetsang a lifaha tsa lebone la infrared LED ho potoloho ea transmitter, e ka tsebang hantle hore na e sebetsa joang. Ha u lekanya motlakase o sebetsang lipheletsong tse peli tsa tube, hangata ke zero tlas'a static (ke hore, ha konopo e sa hatelloa), 'me matla (ha o tobetsa konopo e itseng) a tla qhomela ho boleng bo fokolang ba motlakase, hobane khouto ea tsamaiso ea hole e tla ba Sebopeho sa mokhoa, sebopeho sa potoloho ea koloi le motlakase oa motlakase o sebetsang, boleng ba motlakase hangata bo pakeng tsa 0.1 le 0.85V. Haeba boleng bo se bo bongata haholo kapa phapang e ngata haholo, o ka tseba hore mabone a lebone la infrared LED a sebetsa ka mokhoa o sa tloaelehang. Lifaha tsa lebone la infrared LED li lokela ho bolokoa li hloekile li bile li tiile, haholo-holo karolo ea phetisetso e chitja ea karolo e ka pele ea pheletso e ka pele e ke ke ea ba le litšila tse joalo ka litšila, kapa tšenyo ea likhohlano. Ketsahalo ea ho hasana e ama ka ho toba ho ata ha leseli la infrared. Leseli le ka fokotsa kutlo ea remote control le ho fokotsa sebaka sa taolo. Ha o ntse o sebetsa ts'ebetsong ea lifaha tsa lebone la infrared LED, litekanyetso tsa bona ha lia lokela ho feta moeli. Ka hona, ha u nkela mohlala oa khetho sebaka, ela hloko mohlala le litekanyetso tsa tube ea pele. Ho phaella moo, ha ua lokela ho fetola mabone a lebone la infrared LED ka ho rata. Hobane mefuta e mengata ea maqhubu a khanya ea infrared e pharalletse haholo, lifaha tsa lebone la infrared LED li tlameha ho penta ka diode ea infrared, ho seng joalo e tla ama kutlo ea taolo e hole mme e be e tsoa taolong. Ka hona, ha u nkela mofuta oa khetho sebaka, etsa bonnete ba hore u ela hloko likarolo tsa leqhubu la leqhubu la leseli la infrared le khantšitseng leseli la infrared. Lifaha tsa lebone la infrared LED li na le boima bo tlase, 'me ts'ebetso ea tsona ea ho hanyetsa mocheso o phahameng o mpefala. E le ho qoba tšenyo, ntlha ea solder e lokela ho ba hole le motso oa lithapo, 'me mocheso oa welding ha oa lokela ho ba o phahameng haholo. Nako ea welding ha ea lokela ho ba telele haholo. Ho molemo ho e sebelisa. Metal gardenia pinch motso oa lithakhisa ho thusa ho qhala mocheso. Ho lokisoa ha sesebelisoa sa pinwing ho lokela ho phethoa pele ho tjheseletsa, 'me tube le pin ha lia lokela ho hatelloa nakong ea ho cheselletsa. Mabapi le tsebo ea lifaha tsa lebone tsa infrared LED, ke tla hlalosa mona kajeno. Ka mor'a ho nahana ka boitsebiso bo eketsehileng ba lebone la lebone la LED, ka kopo tsoela pele ho ela hloko Xiaobian. Haeba o hloka lifaha tsa lebone tsa LED, o ka ikopanya le basebeletsi ba rona ba semmuso ba litšebeletso tsa bareki!
