Yuav ua li cas 395nm Floodlights txawv ntawm 365nm UV teeb?

Txhua tus neeg koom nrog hauv kev yuav khoom siv UV muaj feem cuam tshuam nrog kev xaiv ntawm395nm uaib 365nm. Thaum qhov sib txawv tsuas yog 30 nanometers, tus nqi sib txawv tuaj yeem ua tau ob peb -fold, thiab cov txiaj ntsig kev ua tau zoo tuaj yeem ua rau muaj kev ntxhov siab. Qee cov neeg siv yuav 395nm floodlights rau resin curing tsuas yog nrhiav tau qhov kev poob siab; lwm tus siv 365nm teeb nyem los kuaj xyuas qhov loj -tej xau tab sis tawm tsam kom pom meej txawm tias siv sijhawm ntev. Qhov teeb meem yog tsis tshua muaj khoom zoo; es, feem ntau nws yog ib qho teeb meem ntawm kev xaiv hom tsis ncaj ncees rau txoj haujlwm.

Tsab ntawv xov xwm no qhia meej qhov sib txawv ntawm ob hom UV teeb ci no, pab koj xaiv txoj cai raws li koj cov kev xav tau tshwj xeeb thiab tsis txhob muaj teeb meem ntau.

Ultraviolet (UV) lub teeb feem ntau categorized los ntawm wavelength rau UVA (315–400nm), UVB, thiab UVC. Ob leeg 395nm thiab 365nm poob rau hauv UVA (ntev-wave UV) spectrum; thaum lawv ua rau muaj kev pheej hmoo tsawg dua rau tib neeg lub cev dua li UVC, qhov no tsis txhais tau tias nws muaj kev nyab xeeb los saib lawv ntawm qhov muag liab qab lossis nthuav tawm daim tawv nqaij rau lawv mus ntev.

Qhov sib txawv tseem ceeb nyob rau hauv lawv lub cev lub cev: wavelengths ze dua rau pom lub teeb (xws li 395nm) feem ntau muaj qis zog tab sis txawv ntawm kev nkag mus thiab qhov sib xws ntawm thaj chaw illuminated. Hloov pauv, luv luv wavelengths (xws li 365nm) feem ntau muab lub zog ntau dua thiab muaj txiaj ntsig zoo ntawm cov khoom siv fluorescent zoo siab. Cov yam ntxwv ntawm lub cev no ncaj qha txiav txim siab rau cov ntawv thov uas txhua tus yog qhov zoo tshaj plaws.

365nm yog suav tias yog "classic wavelength" nyob rau hauv lub tshav pob ntawm UV fluorescence nrhiav kom tau, thiab ntau yam kev lag luam - qauv kev soj ntsuam raws tu qauv yog tsim los ntawm no tshwj xeeb wavelength. Nws qhov zoo muaj xws li:

Kev ua haujlwm ruaj khov rau kev ua haujlwm zoo rau feem ntau cov fluorescent dyes, fluorescent agents, thiab minerals; dav pom nyob rau hauv kev lag luam.

Feem ntau muaj nyob rau hauv handheld, cwj mem -style, thiab lub rooj me me- teeb hom, ua kom yooj yim ze - ntau yam, tshuaj xyuas kom ntxaws.

Kev siv dav hauv cov ntawv thov xws li kev kuaj xyuas qhov tsis zoo (tshwj xeeb yog kev kuaj fluorescent penetrant hauv NDT), kev txheeb xyuas cov txiaj ntsig, tshawb pom cov tsiaj tso zis lossis cov kua dej hauv lub cev, kev txheeb xyuas cov ntxhia, thiab hmo ntuj - sij hawm yos hav zoov scorpion.

Txij li ntau lub teb chaws cov qauv thiab kev lag luam tshwj xeeb (xws li cov hauv NDT teb) qhia meej meej rau kev siv 365nm wavelength, 365nm yog qhov kev xaiv zoo tshaj plaws rau kev ua raws li - cov ntawv tsav tsheb.

395nm lub teeb nyob ze heev rau ciam teb ntawm pom violet teeb. Cov LEDs ntawm tus kheej ntawm lub wavelength no muaj zog dua kev hloov dua siab tshiab, ua kom yooj yim rau kev tsim cov siab -faiv fab "floodlights" muaj peev xwm ua kom pom qhov chaw loj. Nws cov yam ntxwv muaj xws li:

Lub teeb pom kev loj loj thiab cov kab teeb pom kev sib xws, ua rau nws tsim nyog rau kev npog thaj chaw ua haujlwm ntau dua li tsuas yog qhov chaw - tshawb xyuas cov ntsiab lus tshwj xeeb.

Higher power density per unit area is achievable, making it common in industrial applications like resin curing and UV adhesive curing.
Qee cov khoom muaj cov kiv cua txias lossis cov dab dej kub los txhawb kev ua haujlwm ntev, tsis tu ncua.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias, vim nws qhov ntev wavelength, 395nm lub teeb yuav ua rau muaj zog fluorescence excitation dua 365nm lub teeb. Yog li, yog tias tus neeg siv khoom xav tau qhov tseem ceeb yog txhawm rau txheeb xyuas cov lus teb fluorescent, 395nm teeb pom kev zoo yuav tsis yog qhov kev xaiv zoo.

Qhov no yog qhov teeb meem tshwm sim thaum kev yuav khoom. Tib yam fluorescent - cim khoom yuav ci ntsa iab nyob rau hauv lub teeb 365nm tab sis tshwm sim dim hauv 395nm lub teeb (los yog vice versa); Qhov no yog nyob ntawm qhov wavelength ntawm cov tshuaj fluorescent tshwj xeeb yog rhiab dua rau. Hauv luv luv:

Yog tias koj xav tau "paub meej faint fluorescent cov ntsiab lus" (piv txwv li, cov kab nrib pleb hauv qhov tsis pom kev, cov kab seem seem) → 365nm muaj qhov zoo sib xws.

Yog tias koj xav tau "loj- thaj tsam kev pab them nqi, kho sai, lossis kev teeb pom kev dav dav" (xws li UV nplaum kho, loj- kev kho saum npoo) → 395nm dej nyab teeb pom kev zoo dua.

Yog tias koj tsis paub meej tias lub wavelength twg cov khoom siv fluorescent tshwj xeeb yog qhov xav tau, nws raug nquahu kom ua qhov me me -batch kuaj ua ntej yuav ntau yam kom tsis txhob yuav cov khoom tsis raug.

Daim ntawv thov Scenario Ntau qhov haum Wavelength

Muaj NDT (Fluorescent Penetrant / Sib Nqus Particle Test):365nm ua

Nyiaj thiab ID Kev Ruaj Ntseg Pov Thawj:365nm ua

Pet Urine Stain and Bodily Fluid Detection:365nm ua

UV Adhesive / Resin Curing:395nm ua

Loj - cheeb tsam Surface Fluorescence Inspection, Theem/Decorative Lighting:395nm ua

Mineral thiab Gemstone Identification:Feem ntau 365nm (txawm tias qee cov zaub mov kuj ua rau 395nm)

Raws li pom, 365nm yog qhov zoo dua rau "kev tshuaj xyuas qhov tseeb" xav tau, thaum 395nm yog qhov zoo dua rau "kho thiab dav- thaj tsam teeb pom kev" xav tau; Nws tsis yog ib qho teeb meem ntawm ib qho ua tau zoo dua li lwm tus, tab sis qhov sib txawv ntawm qhov kev npaj ua haujlwm.

Tshaj li qhov wavelength nws tus kheej, xav txog cov hauv qab no thaum yuav khoom:

Irradiance (mW / cm²):Ncaj qha cuam tshuam kev kho ceev lossis kev soj ntsuam rhiab heev; Feem ntau, ntau dua irradiance yields cov txiaj ntsig tau tshaj tawm rau qhov muab wavelength.

Beam Uniformity:Rau cov teeb pom kev nyab xeeb, xyuas tshwj xeeb rau kev siv zog loj heev - tawm ntawm ntug.

Lub Sijhawm Ua Haujlwm Nruam thiab Kev Tiv Thaiv Thaum Tshav Kub Kub:Cov yam tseem ceeb los xyuas kom muaj kev lag luam tas mus li -siv scenarios.

Ua raws li Kev Tshawb Fawb Kev Lag Luam Cov Qauv:Rau cov xwm txheej tswj hwm zoo li NDT, paub meej tias lub wavelength thiab irradiance ua tau raws li cov lus qhia tshwj xeeb.

Qhov kev xaiv ntawm 395nm floodlights thiab 365nm UV teeb tsis yog ib qho teeb meem ntawm "siab dua vs. qis" specifications; lawv yog ob hom khoom tsim los rau cov ntawv thov sib txawv: 365nm excels ntawm precision fluorescence tshuaj xyuas, thaum 395nm excels loj - cheeb tsam kho thiab illumination. Tus yuam sij rau kev xaiv tus qauv yog tsis nyob rau hauv uas wavelength yog "ntau dua," tab sis nyob rau hauv qhov kev ua tau zoo kho qhov muag xav tau rau koj qhov kev thov tiag tiag scenario.

Yog tias koj tsis paub meej tias yuav xaiv 395nm lossis 365nm rau koj daim ntawv thov, lossis yog tias koj xav tau cov lus pom zoo txog qhov tsim nyog irradiance thiab teeb qauv raws li cov ntaub ntawv tshwj xeeb raug tshuaj xyuas lossis hom nplaum raug kho, thov koj xav tiv tauj peb. Peb tuaj yeem muab cov lus qhia xaiv thiab cov ncauj lus kom ntxaws txog cov khoom lag luam raws li koj qhov kev xav tau tshwj xeeb.
