Uyini umehluko phakathi kwe-365nm ne-395nm UV LED? Ukuqhathanisa
Uyini umehluko phakathi kwe-365nm ne-395nm UV LED? Uyini umehluko phakathi kwe-365nm ne-395nm UV LED? Yini eyenza le wavelength ethile ikhethwe kakhulu kuzilungiselelo zesayensi, zezimboni kanye ne-forensic? Ukunikeza izimpendulo zale mibuzo, kanye nezinga elifanele lemininingwane, kanye nenduduzo yomuntu, le ndatshana yonke inikezelwe kuyo. Izinto eziyisisekelo ze-UV LED Wavelength Umehluko Ukukhanya kwe-ultraviolet (UV) kukhishwa ngobude obuphakathi kwama-nanometer ayi-100 kuya ku-400 nm. Imvamisa ihlukaniswe yaba izingxenye ezintathu: - UVA (315-400 nm) - UVB (280-315 nm) - UVC (100-280) I-365nm UV LED ikhipha ukukhanya okuwela ngaphansi kwe-UVA spectrum, okusho ukuthi ayiyingozi kakhulu kune-UVB noma i-UVC, kepha inikeza usizo olukhulu ekusetshenzisweni okuhlukile. Yini eyenza i- 365nm wavelength ekhethekile kwamanye ama-LED e-UV ukuthi ama-LED we-UV angama-365nm amaningi iqiniso lokuthi i-UV LED 395nm ihlukile ezakhiweni zobuchwepheshe. Njengoba kushiwo ngaphambili, zombili i-UV-B zisusa ukugcizelela kwazo futhi ziyifake ku-UV-A, kepha zombili zinezici ezichazayo ezakha ukusebenza nokusebenza kwazo. Wavelength and Photon Energy Ama-LED we-UV angama-365 nm akhiqiza ukukhishwa okunamandla kokukhanya kwe-UV-A ngenxa yamandla abo aphezulu we-photon (3.40 eV). Lokhu kuholela ekusebenzisaneni okunamandla kakhulu nezinto ze-fluorescent futhi kuthuthukise ukusebenza kokwelapha kwe-UV. Ama-LED aphansi angama-395nm akhipha ukukhanya ngobude obude kancane namandla aphansi we-photon (3.14 eV), okuholela ekujabuleni okuncane kwe-fluorescence, kepha kunokubonakala okungcono. Ukukhishwa kokukhanya okubonakalayo nokukhishwa kwe-UV Ama-LED angama-365nm akhiqiza ukukhanya okucishe ...
