Ir iholele kuhlelo lokusebenza lwe-IT

I-wavelthth ye-LED ye-infrared (IR) ye-infrared (ir), eyaziwa nangokuthi i-diode ekhanyisa ukukhanya, iwela ngaphakathi kwe-infrared deptrum. Ukuze uqonde i-wavelength ye-IR LED, kubalulekile ukuqonda umqondo wokukhanya kanye ne-electromagnetic spectrum.
Ukukhanya kuyindlela yemisebe ye-electromagnetic equkethe izinhlayiya ezibizwa ngokuthi ama-photons. Lezi zithombe zihamba ngamaza, futhi ibanga eliphakathi kweziqongo ezimbili ezilandelanayo noma umkhombe wegagasi laziwa ngokuthi i-wavelength yayo. I-wavenwength yokukhanya imvamisa ilinganiswa kuma-nanometers (nm) noma ama-micrometers (μm).
I-electromagnetic spectrum ibandakanya zonke izinhlobo zemisebe ye-electromagnetic, ezisukela kuma-rays aphezulu we-gamma kanye nama-X-ray kuya ku-Implen Light, imisebe ye-infrared, ama-microwaves kanye namagagasi omsakazo. Isifunda ngasinye se-spectrum sibonakaliswa ububanzi baso we-wavenweth.
Imisebe ye-infrared ilele ngaphezu kwalokho okubonakalayo okubonakalayo okubonakalayo, okunama-wavelength amade kanye namafrikhwensi aphansi. Ihlukaniswe izigaba ezintathu eziphambili: eduze-infrared (NIR), Mid-infrared (MIR), futhi i-FE FER (FIR). Uhla lwe-wavenweth olunye lwesigaba ngasinye lungahluka ngokuya ngomthombo kanye nesicelo. Futhi i-IR LED ingaba uhlobo lwe-SMD LED kanye nohlobo lwamalambu we-LED. Iphakheji njenge-LED ye-2835 ye-SMD, i-3528 ye-SMD LED, i-5050 SMD LED kanye ne-5mm i-HOLEL LED, 3mm nge-Hole LED konke kuyatholakala efektri yethu.
I-Ir Leds yenzelwe ukukhipha ukukhanya kububanzi obungenamkhawulo. Zinguhlobo lwe-diode ezikhipha ukukhanya lapho kufakwa khona lapho kufakwa khona i-Electric yamanje. I-wavelength ye-IR LED inqunywa ngezinto zokwakha kanye nokwakhiwa okusetshenziselwa ukwakhiwa kwayo.
Imvamisa, i-IR LEDS i-EMIT Light ebangeni eliseduze le-infrared, ngama-wavelengths asukela ku-700nm kuya ku-1,500nm (noma u-0.7 μm kuya ku-1 μM). Kodwa-ke, i-wavelength eqondile ingahluka ngokuya ngohlobo oluthile nenhloso ye-IR LED.
Isibonelo, ukusetshenziswa okujwayelekile kwama-LED asondelene ne-infrared kufaka phakathi izilawuli ezikude, ukuxhumana kwe-Optical, kanye nezinzwa zokusondela. Lawa ma-LED avame ukukhipha ukukhanya endaweni yakwa-850nm. Le Wavelength iwela ngaphakathi kobubanzi be-spectrum eseduze ne-infrared futhi ayibonakali esweni lomuntu.
Ezinye izinhlobo ze-IR LEDs, ezinjengalezo ezisetshenziswe kumadivayisi wombono wobusuku noma ezinhlelweni zokuphepha, zingakhipha ukukhanya kuma-wavelength amade, imvamisa ebangeni eliphakathi nendawo. Ama-wavelength aphakathi nendawo ajwayelekile aqala kusuka ku-1 μm kuya ku-10 μm. Lawa ma-wavelength amade awusizo ekutholeni amasiginesha okushisa futhi athumbe izithombe ebumnyameni.
I-wavelength ethile ye-IR LED ibalulekile ngoba izinto ezahlukahlukene nezinto ezisebenzisana ngokuhlukile ngama-wavelength ahlukene wemisebe ye-infrared. Isibonelo, izinto ezithile zingadonsa noma zibonise ama-wavelength athile, abenze balungele izinhlelo zokusebenza ezahlukahlukene. Ngokukhetha i-wavelthth efanelekile, i-IR LEDs ingenziwa kahle imisebenzi ethile.

Ekuphetheni, i-wavelength ye-LED ye-IR iwela ngaphakathi kwe-infrared deptrum, elele ngaphezu kwebanga lokukhanya elibonakalayo. I-Ir LEDs imvamisa ikhipha ukukhanya ohlwini oluseduze lwe-infrared, ngama-wavelengths asuka ku-700 nm kuya ku-1 000 nm. Kodwa-ke, i-wavelength eqondile ingahluka ngokuya ngohlobo oluthile nenhloso ye-IR LED, ngokukhanya okuthile ebangeni eliphakathi nendawo. Ukuqonda i-wavenwength ye-IR LEDs kubalulekile ukuklama nokuzisebenzisa kuzicelo ezahlukahlukene, njengokulawula okukude, amadivayisi wokubuka ebusuku, nezinhlelo zokuphepha.
