Zifundise Ukuthi Ungawahlukanisa Kanjani Amashubhu Adluliselwa Nge-infrared kanye Nokwamukela I-infrared

Amashubhu okwethulwa kobuhlalu besibani se-infrared LED kanye neshubhu etholayo yobuhlalu besibani se-infrared LED abizwa ngokuthi ubuhlalu besibani se-infrared LED. Ukuma kobuhlalu besibani se-infrared LED kufana nobuhlalu obuyindilinga be-LED obujwayelekile. Lapho uqala ukuxhumana nobuhlalu besibani se-infrared LED, kunzima ukuhlukanisa umthumeli wobuhlalu besibani se-infrared LED kanye neshubhu eyamukelayo yobuhlalu besibani se-infrared LED. R & Abasebenzi bakwa-D baveze ukuthi indlela yokwahlulela ingasetshenziswa ukuhlukanisa: ukusebenzisa i-multimeter ukukala ukuhlonza ukukala ukumelana kwe-polar kobuhlalu besibani se-infrared LED nge-multimeter ukuze kutholwe ukuthi ubuhlalu besibani se-infrared LED. Nquma 1: Ngesikhathi sobuhlalu besibani se-infrared LED, ukukalwa kwemitha kuyancishiswa ngaphansi kwesimo sokukhanya kwe-irradiation, ukumelana phambili kweshubhu elidlulisiwe kuncane, ukumelana okuphambene kukhulu, futhi ipeni letafula elimnyama lihle (izikhonkwane ezinde), ukumelana kuxhunywe ku-resistor, kanye ne-resistor Small (1K —20K) iyishubhu yokudlulisa yobuhlalu besibani se-infrared LED. Ukumelana okukhulu nokuhlehlayo yishubhu etholayo yobuhlalu besibani se-infrared LED. Isahlulelo sesi-2: Uma ithebula elimnyama lixhunywe esigxotsheni esinegethivu ukumelana okukhulu kobuhlalu besibani se-infrared LED. Lapho ukumelana kukuncane futhi isikhombi semitha yezinhloso ezintathu sishintsha ngokukhanya nobuthaka bokukhanya, isikhombisi sinyakazisa ishubhu lokwamukela ubuhlalu besibani se-infrared. Ukwahlulela kokuhlola okunamandla kagesi kobuhlalu besibani se-infrared LED Singaqale sisebenzise ubuhlalu besibani se-LED futhi —Lokhu kumelana kanye nobuhlalu belambu le-infrared LED obuhloliwe buxhunywe ochungechungeni, futhi ubuhlalu besibani se-LED busetshenziselwa ukubonisa isimo sokusebenza seshubhu ye-infrared tube. Sebenzisa isilawuli kude (i-DVD remote control, njll.) ukuze ucindezele noma yimuphi ukhiye wesilawuli kude kushubhu yokuhlola. Uma i-LED ikhanya, ithubhu iyishubhu eyamukelayo yobuhlalu besibani se-infrared LED. Uma ingakhanyi, iyishubhu yokudlulisela yobuhlalu besibani se-infrared LED. Linganisa ukusebenza kwe-voltage yokusebenza yobuhlalu besibani se-infrared LED kusekethe yesidlulisi, esingavele sinqume ukuthi ukusebenza kwayo kusebenza kanjani. Lapho ukala i-voltage yokusebenza kuzo zombili iziphetho zeshubhu, imvamisa iba ngu-zero ngaphansi kwe-static (okungukuthi, lapho inkinobho ingacindezelwe), futhi i-dynamic (uma ucindezela inkinobho ethile) izogxumela kunani elincane le-voltage, ngoba ukufakwa kwekhodi yesistimu yokulawula kude kuyoba Isakhiwo sendlela, isakhiwo sesifunda sedrayivu kanye ne-voltage ye-voltage yamandla okusebenza, inani le-voltage ngokuvamile liphakathi kuka-0.1 no-0.85V. Uma inani lingelikhulu kakhulu noma umehluko mkhulu kakhulu, unganquma ukuthi ubuhlalu besibani se-infrared LED busebenza ngendlela engavamile. Ubuhlalu besibani se-infrared LED kufanele bugcinwe buhlanzekile futhi buqinile, ikakhulukazi ingxenye eyindilinga yengxenye engaphambili yesiphelo esingaphambili ayikwazi ukuba khona izinto ezingcolisayo ezinjengokungcola, noma ukulimala okungqubuzanayo. Ukwenzeka kokuhlakazeka kuthinta ngqo ukusabalala kokukhanya kwe-infrared. Ukukhanya kungase kunciphise ukuzwela kwesilawuli kude futhi kunciphise ibanga lokulawula. Enkambweni yokusebenza kwinqubo yobuhlalu besibani se-infrared LED, imingcele yabo akufanele idlule umkhawulo. Ngakho-ke, lapho ushintsha imodeli yokukhetha, qaphela imodeli kanye nemingcele ye-tube yokuqala. Ngaphezu kwalokho, akumele uguqule ubuhlalu besibani se-infrared LED ngokuthanda kwakho. Ngenxa yokuthi ububanzi bamaza okukhanya kwe-infrared bubanzi kakhulu, ubuhlalu besibani se-infrared LED kumele bubhanqwe ne-infrared diode, ngaphandle kwalokho kuzothinta ukuzwela kwesilawuli kude futhi kubangele ukungalawuleki. Ngakho-ke, lapho ushintsha uhlobo lokukhetha, qiniseka ukuthi unaka imingcele ye-wavelength yesignali yokukhanya kwe-infrared ekhipha ukukhanya kwe-infrared. Ubuhlalu besibani se-infrared LED bunobunzima obuphansi, futhi ukusebenza kwabo kokumelana nezinga lokushisa kubi kakhulu. Ukuze ugweme umonakalo, iphuzu le-solder kufanele libe kude nempande yezikhonkwane, futhi izinga lokushisa lokushisela akufanele libe phezulu kakhulu. Isikhathi sokushisela akufanele sibe side kakhulu. Kungcono ukuyisebenzisa. I-Metal gardenia ncinza impande yezikhonkwane ukusiza ukuqeda ukushisa. Ukulungiswa kwe-pinwing switch kufanele kuqedwe ngaphambi kokushisela, futhi ithubhu nephini akufanele kugcizelelwe ngesikhathi sokushisela. Mayelana nolwazi lobuhlalu besibani se-infrared LED, ngizochaza lapha namuhla. Ngemva kokucabanga ngolunye ulwazi lobuhlalu besibani se-LED, sicela uqhubeke nokunaka i-Xiaobian. Uma udinga ubuhlalu besibani se-LED, ungaxhumana nabasebenzi bethu abasemthethweni benkonzo yamakhasimende!
