UV blacklight ua li cas?

Ib hom teeb ci tshwj xeeb uas tsim hluav taws xob ultraviolet (UV) uas tsis pom ntawm tib neeg lub qhov muag yog hu uaUV teeb,los yog ultraviolet blacklight. Tsis zoo li cov teeb ci LED li niaj zaus, nws lub hom phiaj tseem ceeb yog los txhawb cov fluorescence lossis phosphorescence hauv cov ntaub ntawv tshwj xeeb. Vim nws lub teeb sib txawv -emitting zog, nws tau siv dav hauv ntau qhov kev lag luam. Txhawm rau pab cov kws tshaj lij kev lag luam thiab cov neeg siv nkag siab zoo dua thiab siv UV teeb pom kev zoo, kab lus no muab cov lus piav qhia luv luv ntawm lawv txoj haujlwm kev ua haujlwm, teev cov xwm txheej ntawm daim ntawv thov, thiab muab cov ntsiab lus tseem ceeb rau kev siv.

Cov khoom ntawm ultraviolet hluav taws xob thiab cov ntaub ntawv fluorescent tsim lub hauv paus ntawm UV blacklight kev ua haujlwm, uas tuaj yeem suav nrog hauv ob kauj ruam yooj yim:

UVA lub teeb (wavelength 320-400 nm), uas yog pom tsis tau rau tib neeg lub qhov muag tab sis muaj kev nkag tau zoo thiab muaj peev xwm ua kom muaj zog, yog thawj UV hluav taws xob tawm los ntawm UV blacklights.

Kev zoo siab fluorescence: Thaum cov khoom siv fluorescent (xws li fluorescent dyes thiab phosphors) raug UVA hluav taws xob, lawv cov hluav taws xob nqus hluav taws xob, nce mus rau qib siab zog, thiab tom qab ntawd tso tawm lub zog raws li pom lub teeb thaum lawv rov qab los rau hauv av, tsim kom muaj "fluorescent effect" uas peb pom.

Txhawm rau muab nws luv luv, UV blacklights "hloov" lub teeb pom tsis pom UV rau hauv cov teeb pom kev zoo siv cov ntaub ntawv tshwj xeeb es tsis ncaj qha emitting lub teeb pom kev.

UV blacklights yog dav siv nyob rau hauv ntau yam kev lag luam vim lawv tshwj xeeb fluorescence excitation muaj nuj nqi. Cov hauv qab no yog qee qhov xwm txheej ntawm daim ntawv thov:

Kev txheeb xyuas kev tiv thaiv- cov cim cuav ntawm cov ntawv nyiaj, ntawv hla tebchaws, daim ntawv pov thawj, thiab cov ntawv cim khoom yog ib feem ntawm kev ruaj ntseg thiab tiv thaiv- cuav. Nyob rau hauv UV blacklight, cov tshuaj tiv thaiv - cov qauv luam tawm nrog fluorescent number case yuav pom meej meej, ua qhov tseeb yooj yim rau kev pom.

Kev kho mob thiab kev huv: Nws yog siv hauv tsev kho mob thiab chaw kuaj mob txhawm rau txheeb xyuas cov kab mob, cov kab mob fungal, thiab cov stains uas tsis yooj yim pom ntawm qhov muag liab qab (xws li cov ntshav lossis cov zis stains), uas yuav pab txhim kho ib puag ncig kev huv thiab tshawb pom qhov tseeb.

Bars, KTVs, chaw ua si, thiab lwm qhov chaw siv kev lom zem thiab kho kom zoo nkauj. Nyob rau hauv UV blacklights, fluorescent xim, kho kom zoo nkauj, thiab khaub ncaws yuav pom cov xim tiag tiag, ua rau pom qhov txawv txav.

Kev Tshawb Nrhiav Kev Lag Luam: Siv los nrhiav qhov tsis zoo, qhov dej xau, thiab tawg hauv cov khoom lag luam (xws li cov khoom siv hluav taws xob thiab tsheb). Cov teeb meem yuav pom nyob rau hauv UV blacklight tom qab ntxiv fluorescent penetrant, ua kom nrhiav tau yooj yim dua.

Thaum siv UV blacklights, nco ntsoov cov hauv qab no los lav lawv lub neej ntev thiab kev nyab xeeb:

Tsis txhob siv hluav taws xob ncaj qha rau tib neeg lub cev: Thaum siv UVA lub teeb rau lub sijhawm ntev, yuav tsum hnav hnab looj tes thiab tsom iav tiv thaiv kom tsis txhob muaj kev puas tsuaj rau daim tawv nqaij thiab qhov muag.

Xaiv qhov tsim nyog wavelength thiab lub zog: UV blacklights ntawm ntau lub zog thiab wavelengths yog xav tau rau ntau yam kev thov (xws li, UVA rau kev tiv thaiv- cuav, UVB rau kev tshawb pom ib nrab), yog li kev xaiv yuav tsum tau ua raws li qhov xav tau tiag tiag.

Kev saib xyuas tsis tu ncua: Khaws lub teeb rau hauv qhov chaw qhuav, txias kom tsis txhob ya raws kev puas tsuaj rau cov khoom sab hauv; khaws lub teeb saum npoo kom huv si kom tsis txhob muaj plua plav los ntawm kev thaiv lub teeb emission.
