Kuyini ukukhethwa kwe-Wavelength (365-405nm)?

Ukuchaza ukukhethwa kwe-wavelength (365 - 405 nm) kudinga ukuqonda kwe-UV LED Systems, ikakhulukazi isimo sokusabalalisa ukukhanya. Lapha, ukusabalalisa ukukhanya kuphathelene nebanga phakathi kwamagagasi okukhanya. Ngakho-ke, ukuthola amandla aqondile, ukuhlanganiswa nezindawo ezithile, kanye nokusebenzisana kwe-365 - 405 nm nemisebe ye-UV kuyisikhundla sezicelo eziningi zobunjiniyela nezokwelapha. Kulesi simo, abaqali bezithombe zisebenza ngokumuncwa kwamandla e-UV, okuholela ezinqubweni eziyisisekelo zamakhemikhali ezifana:  

• Ukumboza nokunamathisela i-photopolymerization

•Ukubopha ezindaweni ezibonakalayo ku-optics ne-elekthronikhi.  

• Inzalo ezinhlelweni zomoya namanzi (hhayi i-UV-C)

• Ukuphulukisa ukunemba kuma-PCB

Iyunithi ngayinye yamandla e-photonic ihlotshaniswa nezimo ezithile eziphathelene nokujula kokuphulukisa, ukunamathela, isikhathi sokuphendula, kanye nephrofayili yokushisa. Isibonelo, i-365nm ingena ngokujulile, kanti i-405nm ipholile futhi ithambile ezintweni ezibuthakathaka. Ukukhetha ubude be-wavelength ngaphakathi kokukhethwa kwe-Wavelength (365-405 nm) kubalulekile njengoba kuthuthukisa ukusebenza nokuhambisana kwezinto zokwakha nohlelo lokuphulukisa lwe-UV, kanye nokwakhiwa kohlelo.  

Kungani lolu hlu? Izinzuzo zesikhathi esingu-365-405 nm?

Leli bhendi libekwe ngobuchule maphakathi ne-UV-A futhi linomngcele ezifundeni ezibonakalayo zokukhanya eziseduze, ngakho-ke kuyasiza ekusetshenzisweni okuningi kwama-LED e-UV. Uhla lufinyelela ekuhlanganeni okuhle phakathi kwalezi zinto ezintathu: ukuchayeka nokusebenza kahle kwezinqubo ze-photochemical, ukuphulukiswa kwento, nokuphepha kwendawo ephathwayo. Nakhu ukuthi sihlaziya kanjani:

• 365 nm

• Ikhiqiza ama-photon anamandla aphezulu ngenkathi ikhipha imisebe emifushane ye-ultraviolet.

•Ithuthukisa ukuphulukiswa okuphelele, ikakhulukazi uma usebenza ngaphansi kwesembozo esicacile.

•Ilungele kakhulu ukubopha amandla aphezulu kwe-optical, izinamathiselo, nokumboza.

•Ukwengamela i-photopolymerization esheshayo yemisebenzi edinga ukuqhuma okukhulu kwamandla.

• Phakathi kwe-385 - 395 nm

•Inikeza indawo ephakathi elinganiselayo phakathi kokujula kokuphulukisa kanye nesivinini sokucubungula.

•Kuvame emhlanganweni wamadivayisi wezokwelapha, i-elekthronikhi, kanye nokumbozwa kwezimboni.

•Iyahambisana cishe nabo bonke abaqali bezithombe zezohwebo.

• 405 nm

•Lokhu kukhishwa kusondele kakhulu ku-spectrum ebonakalayo, okwenza kube mnene ezindaweni ezibucayi.    

• Ukushisa kancane izingxenye ezizwela ezishisayo njengamapulasitiki namabhodi wesifunda.    

•Imiphumela ephephile futhi engaguquguquki ngengozi encane yokulimala kwezinto zokwakha.  

Ukucatshangelwa ngokucophelela ukuma ngaphakathi kwebanga le-365 - 405 nm UV LED spectrum kuzoveza imiphumela emihle futhi kwandiswe impilo yemishini.  

Izicelo ezisekelwe ku-wavelength  

Ukuqonda ukuthi ezinye izimboni zisebenzisa kanjani ama-wavelengths athile e-UV LED kungasiza isu lakho lokukhetha.  

 Amadivaysi wezokwelapha (385-405 nm)  

• Ilungele ukuhlangana kwezingxenye zepulasitiki ezincane, ezibucayi.  
• Ukwelapha ngokunemba ngaphandle kokulimaza okushisayo.  
• Iqinisekisa amalunga angangcolisiwe, ahlanzekile.

Ukupakisha nokuphrinta (395nm)

• Ngezindlela ze-roll-to-roll, ukwelashwa kuyashesha futhi kuyasebenza.
• Iyahambisana nezithombe ezisetshenziswa ekukhiqizeni.
• Ukukhiqizwa kwe-inline ngokubambezeleka okuncane kungenzeka.

I-Electronics (365-385 nm)

• Isebenza ebhodweni nokufaka uphawu lwe-PCB nemicu ye-optical.
• Inikeza amandla amahle esibopho ngokusonteka okuphansi.
• Kunciphisa ingozi yokulimaza izifunda ezibucayi ngenxa yokushisa ngokweqile.

Imishini yeLebhu (365 nm)

• Ihlanganiswe kangcono nengilazi, i-quartz, namapulasitiki athile kulezi zigaba zamagagasi.
• Ithola ukucaca nokuqotho okuphezulu kwesakhiwo.
• Ukuvikela ukungcola ophuzi nokunye ukungcola.

I-UV-A LED Science: I-Bleaching, nokuthi Kungani Ama-Nanometers Kubalulekile

Amandla ahlukene aqhutshwa yi-wavelength ngayinye ye-UV ye-LED.

•365nm ≈ 3.4eV (enamandla)

•405nm ≈ 3.06eV (buthakathaka)

Izinguquko ku-eV zizoletha impendulo ethile evela kubaqalayo bezithombe. Abaqali bezithombe abanamandla8 bavusa ukusabela okujulile ngenkathi abamnene bevame ukuphepha ezindaweni ezibucayi.

Izindlela zokulinganisa ze-Ultraviolet Laser Diode ezikhipha ukukhanya kwama-wavelengths e-UV

Yonke imininingwane ibalulekile ezinhlelweni eziyinkimbinkimbi ezisuselwa kuma-diode akhipha ukukhanya kwe-ultraviolet (UV) (LEDs). Ngaphambi kokuthi kucatshangelwe ukushintsha kwenkomba yokusebenza kanye ne-refractive index ngaphakathi kohlelo, ikhwalithi yokuphulukisa kufanele ihambisane. Amathuluzi wokulinganisa enza kube nokwenzeka ukufeza amaphrinta we-UV anezinhlangothi ezintathu ngokunika amandla ukudubula okuqondile kwe-UV LED ngayinye kubude obudingekayo namandla ezinyathelo ezifana ne-photopolymerization, ukuphulukiswa kokunamathisela, noma ukubopha okubonakalayo.

• Ukuqinisekiswa kokunemba kwama-wavelengths akhishwa yi-UV LEDs kudinga ukusetshenziswa kwama-spectroradiometers. La madivayisi athatha i-spectrum yokukhipha futhi aqinisekise ukuthi uhlelo lukhipha ama-nanometer adingekayo, kungaba yi-365nm, 385nm, 395nm, noma i-405nm. Lokhu kubalulekile ukufanisa okukhiphayo kwama-LED eziqongweni zokumuncwa kwezithombe zokuqalisa ukusabela kahle.
• Ngaphezu kwalokho, amamitha wamandla we-UV nawo alinganisa ukukhanya (mW / cm²) ukugcina ukungaguquguquki kwamandla e-UV, athinta ijubane lokuphulukisa, ukujula, namandla okubopha. Ukuhlangabezana nalezi zindinganiso ezinqubweni eziphezulu kubalulekile, njengoba ngisho nokucwila okuncane ekusebenzeni akwamukeleki.
• Izihlungi ze-Optical zisiza ekuhlolweni okunamandla nokuqondisa ngokunemba ku-elekthronikhi ephezulu kanye ne-optics, njengoba zinquma i-geometry yogongolo, ukuqina kwayo, ngisho nokusha kwayo kwe-spectral ngaphakathi kwezindawo ezigxile kuma-LED e-ultraviolet
• Okokugcina, isoftware yokulinganisa ibalulekile ekuqapheni ukuguga kwe-LED kanye nokwehla kwenani lokukhipha. Njenganoma yibuphi ubuchwepheshe, ama-LED e-UV anamafasitela athile okusebenza ngaphakathi kwawo asebenza kahle kakhulu. Amasheke wesondlo ahleliwe athola ama-glitches afihliwe isikhathi eside ngaphambi kokuba abe yinkinga.  

Ukucatshangelwa  Kwezemvelo Nokuphepha

Ukuphepha kwemvelo, uhla lwe-> 365-405 nm luza nenzuzo eyingqayizivele. Uma kuqhathaniswa nezibani ezijwayelekile ze-UV, ezisebenzisa i-mercury, lezi zikhipha i-zero mercury, ngaleyo ndlela zikhululwe ngokuphelele kunoma iyiphi imfucuza ye-mercury, imfucuza eyingozi, nokukhishwa kwemithetho efanele efana nemithethonqubo ehambisana ne-REACH ne-RoHS.

• Ngenxa yokuntuleka kokukhishwa kwe-280nm (UV-C), lawa ma-UV LED awabeki ingozi ye-ozone, ngakho-ke aphephile ezindaweni ezivaliwe njengamahhovisi, amalabhorethri wezokwelapha, futhi angakhiwa ngokuphepha ezimpahleni zabathengi. Futhi, ukuntuleka kokukhishwa ngezansi \(280nm (UV-C)\) kusho ukuthi akukho ukukhiqizwa kwe-ozone noma ukukhishwa okuyingozi kwezinto eziphilayo okuhambisana nemisebe ye-ionizing (UV).
• Lezi zibani ze-UV nazo zinezinzuzo ezibalulekile. Imisebe ye-UV ebangeni le-365-405 nm iyimisebe engeyona i-ionizing, okusho ukuthi, ngaphansi kokusetshenziswa okujwayelekile, akunakwenzeka kokulimaza i-DNA noma izakhiwo zeselula. Lesi sici siwusizo kumathuluzi ezempilo, amadivayisi e-elekthronikhi, izinhlelo ze-optical, kanye namalabhorethri lapho ukuphepha kwabasebenzi kanye nobuqotho bezinto ezibucayi kuyinto eza kuqala.
• Ukungabi bikho kwemisebe ye-UVC, umthwalo omncane wokushisa, namazinga aphansi okukhishwa konke kunomthelela ekukhethweni kwe-UV LED Wavelength (365-405 nm) kokubili okunembile futhi okuhambisana ne-eco-friendly futhi kuhambisana nomthetho, okubalulekile ezimbonini zanamuhla.

Isiphetho

Njenganoma yisiphi isiyalo, ukukhethwa kwe-UV LED wavelength kufanele kuqinisekiswe ukuthi ukuhlanganiswa kokukhanya ku-365 no-405nm kulinganiselwa nemingcele ethile. Kufanele kucatshangelwe amakhemikhali, amandla, nenqubo, kanye nokuklama nokusetshenziswa.  Ku-UVET, siqinisekisa ubungcweti be-UV LED, abaqali bezithombe, nokuhambisana kwabo kwe-ultraviolet, kanye nama-wavelengths we-bespoke ahleliwe we-OEM. Iziqalo ngisho nama-OEM omhlaba wonke azothatha isinqumo esifanele ngokuqiniseka ngokuphelele nangokusebenza kahle ekukhetheni ubude be-wavelength ngoba ukwesekwa kwethu okungaguquguquki kunikeza isiqondiso esiqinile.
