Vim li cas Photochemical Reactions Xav Tau "Kev Cai Wavelength" UV LED?Cov ntaub ntawv tseem ceeb nthuav tawm cov lus teb
Hauv cov chaw soj nstuam, cov kab ntau lawm, luam ntawv, kho, tshuaj tua kab mob, thiab tshuaj xyuas, ultraviolet (UV) lub teeb yog ib qho khoom siv tsis tau. Txawm li cas los xij, cov teeb hluav taws xob mercury emit dav spectrum ntawm UV teeb, thiab feem ntau tsuas yog ib feem me me ntawm cov wavelengths xwb. Tus so yog nkim lub zog los yog ua rau cov kev xav tsis zoo.
Hnub no,customizable wavelength thiab lub zog UV LED teebyog hloov mercury teeb raws li cov cuab yeej precision hauv thaj chaw photochemistry. Siv cov ntaub ntawv ntsuas tiag tiag los ntawm cov khoom lag luam tshwj xeeb ua piv txwv, tsab xov xwm no piav qhia vim li cas "qhov tseeb wavelength, nqaim ib nrab- dav, thiab kho lub zog" yog qhov tseem ceeb ntawm UV LEDs.
1. Lub voj voog tsis yog "Piv txwv li, qhov zoo dua" - Nws yuav tsum ua kom zoo sib xws
Cov tshuaj tiv thaiv photochemical sib txawv yuav tsum muaj zog photon sib txawv. Qhov luv luv lub wavelength, lub zog ntau dua ib photon, tab sis qhov qis dua qhov tob tob. Cov khoom no muaj ntau txoj kev xaiv wavelength ntawm 254nm txog 440nm, npog UVC, UVB, UVA, thiab ze-UV bands:
| Wavelength Range | Hom Wavelengths | Cov ntawv thov tseem ceeb |

2. Ib nrab Dav (FWHM) – Qhov taw qhia tseem ceeb ntawm UV LED "Purity"
Ntau tus neeg siv tsuas saib lub ncov wavelength tab sis tsis quav ntsejFull Width at Half Maximum (FWHM). FWHM qhia qhov dav ntawm lub ncov spectral - qhov me dua tus nqi, qhov "purer" lub spectrum thiab ntau concentrated lub zog.
Los ntawm cov ntaub ntawv ntsuas spectral (OHSP350UVS) muab rau cov khoom:
| Parameter | Ntsuas tus nqi | Lub ntsiab lus |
|---|---|---|
| Peak wavelength | 2 56,5nm | Point ntawm lub zog siab tshaj plaws |
| Nruab nrab wavelength | 2 57,6nm | Symmetry center ntawm spectrum |
| Ib nrab dav (FWHM) | 12.1nm ua | spectrum nqaim heev; lub zog yog heev concentrated |
| UVC irradiance | 18,241.94 µW/cm² | Siv tau zoo rau kev ua kom tsis muaj menyuam / tawm tsam |
Rau siv: UV band ntawm lub teeb mercury ib txwm muaj FWHM ntawm 20–40nm thiab muaj ntau cov kab spectral tsis muaj txiaj ntsig. A 12.1nm FWHM txhais tau tiastshaj 90% ntawm UV lub zog yog concentrated nyob ze ntawm lub hom phiaj wavelength, zoo heev txhim kho cov tshuaj tiv thaiv efficiency.
Rau kev sim photochemical lossis kev kho kho uas xav tau kev tswj xyuas meej ntawm cov tshuaj tiv thaiv, qhov nqaim-FWHM UV LED muaj qhov zoo dua tsis tuaj yeem hloov.
