Ikufundise indlela yokwahlula iityhubhu eziThunyelwayo ze-infrared kunye noKwamkelwa kwe-infrared

Iityhubhu zokuphehlelelwa kwezibane ze-infrared ze-LED kunye netyhubhu yokufumana amaso esibane se-infrared abizwa ngokuba ngamaso esibane se-infrared. Ubume be-infrared isibane se-LED bufana ne-bead yesibane se-LED eqhelekileyo. Xa uqala ukudibanisa amaso isibane infrared LED, kunzima ukwahlula emitter infrared amaso isibane LED kunye ityhubhu yokufumana infrared amaso isibane LED. R & Abasebenzi be-D bachaza ukuba indlela yokugweba ingasetyenziselwa ukwahlula: ukusebenzisa i-multimeter ukulinganisa ukuchongwa ukulinganisa ukuxhathisa kwe-polar ye-infrared LED amaso isibane kunye ne-multimeter ukugqiba ukuba ngaba i-infrared LED beads. Ukumisela i-1: Ngexesha lokukhanya kwesibane se-infrared LED, umlinganiselo wemitha uyancitshiswa phantsi kwemeko yokukhanya kwe-irradiation, ukuchasana phambili kwe-tube edlulisiweyo kuncinci, ukuchasana kwe-reverse kukhulu, kunye nepeni yetafile emnyama ilungile (izikhonkwane ezide), ukuchasana kuqhagamshelwe kwi-resistor, kunye ne-resistor encinci (1K —20K) yityhubhu yokuhambisa amaso esibane se-infrared LED. Ukuchasana okukhulu kunye nokubuyisela umva ngumbhobho wokufumana amaso e-infrared isibane se-LED. Isigwebo sesi-2: Xa itheyibhile emnyama idityaniswe kwipali engafanelekanga kukuxhathisa okukhulu kweentsimbi zesibane se-infrared LED. Xa ukuchasana kuncinci kwaye isalathisi semitha yeenjongo ezintathu sitshintsha ngokukhanya kunye nobuthathaka bokukhanya, isalathisi sijingisisa i-infrared LED bead ye-bead yokufumana ityhubhu. Isigwebo sovavanyo olunamandla ombane we-infrared LED amaso isibane Singasebenzisa kuqala isibane isibane LED kunye —Oku kuxhathisa kunye ne-infrared infrared LED beads zixhunyiwe kwi-series, kwaye i-bead yesibane se-LED isetyenziselwa ukubonisa isimo sokusebenza setyhubhu ye-infrared. Sebenzisa isilawuli kude (iDVD yolawulo olukude, njl. njl.) ukucofa naliphi na isitshixo sesilawuli kude kumbhobho wovavanyo. Xa i-LED ikhanya, ityhubhu yityhubhu yokufumana amaso e-infrared isibane se-LED. Ukuba ayiqaqambi, yityhubhu yokuhambisa isibane sesibane se-infrared. Ukulinganisa umsinga osebenzayo wombane osebenzayo we-infrared LED amaso isibane kwi-transmitter circuit, enokugqiba ngokulula indlela yokusebenza kwayo. Xa ulinganisa i-voltage esebenzayo kuzo zombini iziphelo zetyhubhu, ihlala ingu-zero phantsi kwe-static (oko kukuthi, xa iqhosha lingacinezelwa), kwaye i-dynamic (xa ucinezela iqhosha elithile) iya kuxhuma kwixabiso elincinci lombane, kuba i-encoding ye-remote control system iya kuba Isakhiwo sendlela, isakhiwo sesekethe ye-drive kunye ne-voltage yokunikezelwa kwamandla okusebenza, ixabiso le-voltage lihlala liphakathi kwe-0.1 kunye ne-0.85V. Ukuba ixabiso alikho kakhulu okanye umahluko mkhulu kakhulu, unokugqiba ukuba amaso esibane se-infrared asebenza ngokungaqhelekanga. Amaso ezibane ze-infrared ze-LED kufuneka zigcinwe zicocekile kwaye zicocekile, ngakumbi indawo yokuhanjiswa kwe-spherical yecala elingaphambili lesiphelo alinakubakho izinto ezingcolisayo ezinjengobumdaka, okanye ukonakala kwefriction. I-phenomenon yokusabalalisa ichaphazela ngokuthe ngqo ukusasazeka kokukhanya kwe-infrared. Ukukhanya kunokunciphisa uvakalelo lolawulo olukude kunye nokunciphisa umgama wolawulo. Kwinkqubo yokusebenza kwinkqubo yokukhanya kwesibane se-infrared LED, iiparamitha zabo akufanele zidlule umda. Ngoko ke, xa utshintsha imodeli yokukhetha, nikela ingqalelo kwimodeli kunye neeparitha zombhobho wokuqala. Ukongeza, akufuneki utshintshe umsinga wokukhanya kwesibane se-infrared LED ngokuthanda kwakho. Ngenxa yokuba uluhlu lwamaza okukhanya kwe-infrared lubanzi kakhulu, iintsimbi zesibane se-infrared ze-infrared kufuneka zidityaniswe ne-infrared diode, kungenjalo iya kuchaphazela ubuntununtunu bolawulo olude kwaye ibangele ngaphandle kolawulo. Ngoko ke, xa utshintshela uhlobo lokukhetha, qiniseka ukuba ubeke ingqalelo kwimilinganiselo ye-wavelength yesignali yokukhanya kwe-infrared ekhupha ukukhanya kwe-infrared. Izibane ze-infrared ze-LED zinobunzima obuphantsi, kwaye ukusebenza kwazo okuphezulu kokumelana nobushushu kubi. Ukuze ugweme umonakalo, indawo ye-solder kufuneka ibe kude neengcambu zezikhonkwane, kwaye ukushisa kwe-welding akufanele kube phezulu kakhulu. Ixesha le-welding akufanele libe lide kakhulu. Kungcono ukuyisebenzisa. Metal gardenia pinch ingcambu yezikhonkwane ukunceda ukutshatyalaliswa kobushushu. Ukulungiswa komtshini we-pinwing kufuneka kugqitywe ngaphambi kwe-welding, kwaye ityhubhu kunye nepini akufanele igxininiswe ngexesha lokudibanisa. Ngokumalunga nolwazi lwezibane zesibane se-infrared, ndiza kuchaza apha namhlanje. Emva kokucinga malunga nolwazi olungakumbi lwesibane se-LED, nceda uqhubeke unikela ingqalelo ku-Xiaobian. Ukuba ufuna iintsimbi zesibane se-LED, ungaqhagamshelana nabasebenzi bethu abasemthethweni benkonzo yabathengi!
