Intshayelelo yeMveliso yesibane sesibane se-infrared kunye neempawu

I-infrared light emitting diode (LED) sisixhobo esikhupha ukukhanya esikufutshane ne-infrared esiguqula amandla ombane abe ngamandla okukhanya. Inoluhlu lweenzuzo ezifana nobukhulu obuncinci, ukusetyenziswa kwamandla aphantsi, kunye nokukhomba okulungileyo. , Ukulawulwa kwe-Optoelectronics, ukulandelela okujoliswe kuyo kunye nezinye iinkqubo, ezineempawu zokusetyenziswa kwamandla aphantsi kunye nomthamo omncinci. Yi-diode esiya kuyisebenzisa yonke imihla. Kusekho ingqalelo eninzi ekukhetheni i-infrared LED. Iimpawu kunye nokusetyenziswa kwamaso wesibane, akunjalo? Iimpawu zezibane ze-infrared ze-LED zisetyenziswe ngokubanzi kulawulo olukude lwe-infrared kwi-TV yemibala, iinkqubo zomsindo kunye nezixhobo ezahlukeneyo zasekhaya. Umgama wolawulo lolawulo olukude unokufikelela ngokubanzi kwi-6 ukuya kwi-8 yeemitha, ekulula kakhulu ukuyisebenzisa. Ngenxa yokuba indlela yolawulo olukude lwe-infrared inkulu, ukuqaliswa kwayo kwe-infrared kunye nokufumana isekethe zonke zinezixhobo ezixhasayo ezipheleleyo. Ezi zixhobo azikho nje ixabiso eliphantsi kwaye lithembekile, kwaye isiphaluka silula kakhulu. Abathandi be-elektroniki banokusebenzisa ezi zixhobo ukudibanisa ulawulo olukude lweenjongo ezahlukeneyo, ezingezona kuphela ezisebenzayo, kodwa zandisa umdla wabo kwimveliso. Iimpawu zezibane ze-infrared ze-LED azibonakali, kwaye amehlo omntu akanakuqaphela. Izibane zesibane se-infrared ezisetyenziswa ngokuqhelekileyo zifana nezibane eziqhelekileyo zesibane se-LED. Ukunciphisa umlinganiselo wokusebenza kwe-pulse nako kunokuba kuhle. I-infrared light etting diode eqhelekileyo, amandla ayo ahlulwe abe ngamacandelo amathathu: amandla amancinci (1MW 10MW), amandla aphakathi (20MW 50MW) kunye ne-LED ephezulu (50mW 100MW okanye ngaphezulu). Xa usebenzisa amandla ahlukeneyo e-infrared light-emitting diodes, umqhubi wamandla ahambelanayo kufuneka aqwalaselwe. Ukwenza ukukhanya kwe-infrared diode kuveliswe, yongeza nje i-voltage ethile ye-pulse frequency kumbhobho wokuqhuba. Xa iimpawu kunye nokusetyenziswa kwezibane ze-infrared ze-LED zikhutshwe nge-infrared diode ukulawula isixhobo esilawulwayo, kukho izinto ezihambelanayo ze-infrared photoelectric conversion kwisixhobo sokulawula, ezifana ne-infrared receive diode, photoelectric transistor, njl. Kukho iindlela ezimbini zetyhubhu yothumelo lwe-infrared kunye neetyhubhu zokufumana i-infrared. Ngokuthe ngqo kubhekiselele kwisihlobo kwiiphelo ezimbini zokuqaliswa kunye nokulawulwa ngumbhobho optical kunye ne-tube yokufumana, kwaye umgama ophakathi ngumgama othile phakathi; umboniso ubhekisela kumbhobho optical kunye ityhubhu yokufumana kunye. Xa udibana ne-reflex, ityhubhu yokufumana ifumana imitha ye-infrared ebuyiselwe kwi-reflection.
