Isethulo somkhiqizo we-infrared LED Lamp Bead kanye nezimpawu

I-infrared light emitting diode (LED) iyisisetshenziswa esikhipha ukukhanya esiseduze ne-infrared esiguqula amandla kagesi abe amandla okukhanya. Inochungechunge lwezinzuzo ezifana nosayizi omncane, ukusetshenziswa kwamandla okuphansi, nokukhomba okuhle. , Ukulawulwa kwe-Optoelectronics, ukulandelela okuhlosiwe nezinye izinhlelo, ezinezici zokusebenzisa amandla aphansi kanye nevolumu encane. Kuyi-diode esizoyisebenzisa nsuku zonke. Kusenokunakwa okuningi ekukhetheni kwe-infrared LED. Izici kanye nokusetshenziswa kwezibani zobuhlalu, akunjalo? Izici zobuhlalu besibani se-infrared LED ziye zasetshenziswa kabanzi kuzilawuli ezikude ze-infrared ku-TV yombala, amasistimu omsindo nemishini ehlukahlukene yasendlini. Ibanga lokulawula lesilawuli kude ngokuvamile lingafinyelela ku-6 kuya ku-8 wamamitha, okulula kakhulu ukulisebenzisa. Ngenxa yokuthi indlela yesilawuli kude se-infrared inkulu, ukwethulwa kwayo kwe-infrared nokwamukela isekethe konke kunamadivayisi aphelele asekelayo. Lawa madivayisi awawona nje amanani aphansi futhi anokwethenjelwa, futhi isifunda silula kakhulu. Abashisekeli be-elekthronikhi bangasebenzisa lawa madivaysi ukuze bahlanganise izilawuli ezikude zezinhloso ezihlukahlukene, ezingezona nje ezisebenzayo, kodwa futhi zandise isithakazelo sabo ekukhiqizeni. Izici zobuhlalu besibani se-infrared LED azibonakali, futhi amehlo omuntu awakwazi ukuqaphela. Ubuhlalu besibani se-infrared LED obusetshenziswa ngokuvamile bufana nobuhlalu belambu be-LED obujwayelekile. Ukunciphisa isilinganiso sokusebenza kwe-pulse nakho kungaba kuhle. I-infrared light emit diode evamile, amandla ayo ahlukaniswe izigaba ezintathu: amandla amancane (1MW 10MW), amandla aphakathi nendawo (20MW 50MW) kanye ne-high -power LED (50mW 100MW noma ngaphezulu). Uma usebenzisa ama-diode ahlukene we-infrared light -emitting diode, umshayeli wamandla ahambisanayo kufanele amiswe. Ukwenza i-infrared glow diode ikhiqizwe, vele ungeze i-voltage ethile ye-pulse epayipini lokushayela. Lapho izici nokusebenzisa ubuhlalu besibani se-infrared LED kukhishwa nge-infrared diode ukulawula idivayisi elawulwayo, kunezingxenye ezihambisanayo zokuguqula ugesi wesithombe sefoni kudivayisi elawulayo, njenge-infrared receiver diode, i-photoelectric transistor, njll. Kunezindlela ezimbili zamashubhu okudlulisa i-infrared namashubhu okwamukela i-infrared. Okuqondile kubhekisela esihlotsheni semikhawulo emibili yokwethulwa kanye nokulawulwa yipayipi le-optical kanye ne-tube yokwamukela, futhi ibanga eliphakathi liyibanga elithile phakathi; i-reflection ibhekisela epayipini le-optical kanye ne-tube yokwamukela ndawonye. Uma uhlangabezana ne-reflex, ishubhu eyamukelayo ithola imisebe ye-infrared ebuyiswa ekukhanyeni.
