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 kuhlanzeke kwe-U A ngenani elincane lokukhanya okubonakalayo. Lokhu kuntuleka kokukhanya kwangemuva kubenza baphelele izinhlelo zokusebenza ezidinga ukuchayeka okuphezulu kwe-UV. Ama-LED angama-395 nm akhipha ukukhanya okubonakalayo kwe-violet, okuwabeka emngceleni we-UV nokukhanya okubonakalayo, ngakho-ke angasebenza njengama-LED ajwayelekile lapho kudingeka khona ukubonakala okubonakalayo. 

Irradiance Efficiency

Ama-LED angama-365nm aziwa ngokukhipha ukukhishwa okunamandla kwamandla e-UV ngenxa yamagagasi amafushane namandla aphezulu we-photon. Ngenxa yalokho, ama-LED angama-365nm aziwa ukuthi asebenza kahle kakhulu ngokuya ngamandla e-UV. Ngakolunye uhlangothi, ama-LED angama-395nm atholakale enemisebe ephansi ye-UV kepha akhuphuke ukukhishwa ekukhanyeni okuseduze.
