310nm UVB LED teebyog ib lub teeb ci semiconductor uas tawm nruab nrab -wave ultraviolet light (UVB, wavelength 280-315nm). Nws cov dej num tseem ceeb yog tsom rau hauv kev kho mob, cov nyhuv lom neeg induction thiab cov khoom siv tshwj xeeb kho. Cov hauv qab no yog nws cov ncauj lus kom ntxaws siv thiab cov yam ntxwv:
1, Lub luag haujlwm tseem ceeb
Kev kho mob thiab kab mob ntawm daim tawv nqaij Phototherapy:
Kev kho mob ntawm psoriasis, vitiligo, eczema, thiab lwm yam: 310nm UVB tuaj yeem tiv thaiv cov tawv nqaij ntau dhau (psoriasis) lossis txhawb kev ua kom melanocyte (vitiligo), thiab yog ib qho kev sib tw rau nqaim -band UVB therapy (NB-UVB).
Txhawb vitamin D synthesis: UVB irradiation ntawm daim tawv nqaij tuaj yeem hloov 7-dehydrocholesterol rau hauv vitamin D₃, uas tuaj yeem pab txhim kho rickets lossis vitamin D tsis txaus (tab sis cov koob tshuaj yuav tsum tau tswj nruj me ntsis).
Qhov zoo: Piv nrog cov tsoos broad -spectrum UVB lossis UVA + photosensitizer (PUVA kho), 310nm LED yog qhov tseeb dua thiab txo qhov kev pheej hmoo ntawm kev kub nyhiab.
2, Kev loj hlob ntawm cov nroj tsuag thiab kev tshawb fawb lom
Kev tswj cov nroj tsuag physiology: UVB tuaj yeem txhawb cov nroj tsuag kom tsim tau UV-cov tshuaj tiv thaiv (xws li anthocyanins), txhim kho kev ntxhov siab lossis txhim kho cov txiv hmab txiv ntoo zoo (xws li ua kom qab zib ntawm txiv hmab txiv ntoo).
Cov ntawv thov kev sim: siv los kawm txog cov teebmeem ntawm UVB ntawm cov hlwb, kab mob lossis DNA (xws li cov qauv kev puas tsuaj UV).
3, Kev lag luam thiab cov ntaub ntawv tshawb fawb
Photocuring: Qee cov txheej tshwj xeeb, cov nplaum lossis 3D luam ntawv resins xav tau UVB los ua kom cov tshuaj tiv thaiv kho, thiab 310nm LED tuaj yeem muab cov wavelengths meej.
Fluorescence detection: Excite cov tshuaj fluorescent tshwj xeeb rau kev tiv thaiv -kev cuav lossis tshuaj ntsuam xyuas.
Piv nrog rau lwm qhov chaw teeb pom kev ultraviolet
Qhov sib txawv ntawm UVC (xws li 254nm):
UVB muaj qhov tsis muaj zog nkag mus (tsuas yog ncav cuag lub epidermis), tsis muaj cov kab mob bactericidal muaj zog, tab sis muaj peev xwm ua kom muaj roj ntsha tseem ceeb.
Piv nrog UVC, UVB muaj tsawg dua kev pheej hmoo ntawm tib neeg raug (tab sis tseem xav tau kev tiv thaiv).
Piv nrog rau cov tsoos mercury teeb:
LED lub teeb qhov chaw yog mercury-dawb, tuaj yeem hloov mus rau thiab tawm tam sim ntawd, muaj ib lub wavelength thiab yooj yim kho, tab sis lub zog thiab lub teeb siv zog yuav qis dua.
4, Kev Tiv Thaiv Kev Nyab Xeeb Kev Nyab Xeeb:
Ntev -lub sij hawm los yog ntau dhau tuaj yeem ua rau daim tawv nqaij erythema, kev laus, thiab ua rau muaj kev pheej hmoo mob qog noj ntshav. Nws yuav tsum tau siv raws li kev taw qhia ntawm tus kws kho mob lossis kws tshaj lij (kev kho mob scenario).
Hnav looj tsom iav UV thaum lub sijhawm ua haujlwm thiab tsis txhob saib ncaj qha ntawm lub teeb ci.
Kev tswj hwm koob tshuaj: Lub sijhawm irradiation thiab kev siv zog yuav tsum tau hloov kho raws li kev kho mob thiab cog daim ntawv thov (xws li mJ / cm², uas feem ntau siv hauv kev kho mob).
Cov cuab yeej siv lub neej: Lub neej ntawm UVB LED yog li 5000-8000 teev, thiab qhov kub thiab txias ib puag ncig tuaj yeem ua kom nrawm nrawm.
Tej yam kev thov scenarios
Cov khoom siv kho mob: cov khoom siv kho mob hauv tsev kho mob, cov cuab yeej kho mob hauv tsev.
Agricultural teeb pom kev zoo: tsev cog khoom ntxiv teeb pom kev zoo lossis kev tswj qoob loo zoo.
Cov cuab yeej tshawb fawb tshawb fawb: kev sim tshuaj lom neeg ultraviolet, cov khoom siv kev laus.
Tus nqi tseem ceeb ntawm310nm UVB LED teebs lus dag nyob rau hauv lawv lub peev xwm los tswj biology, tshwj xeeb tshaj yog nyob rau hauv kev kho mob ntawm daim tawv nqaij kab mob thiab kev ua liaj ua teb, tab sis nws yog tsim nyog los sib npaug kev ua tau zoo thiab kev nyab xeeb. Nrog rau kev txhim kho ntawm LED thev naus laus zis, nws cov txiaj ntsig thiab kev siv ntau yam tseem tab tom nthuav dav, koj tuaj yeem tau txais cov ntaub ntawv ntxiv ntawmhttp://www.benweilight.com
