Ultraviolet (UV) lub teeb yog ib hom hluav taws xob hluav taws xob hluav taws xob uas muaj lub wavelength luv dua li qhov pom lub teeb. Ultraviolet lub teeb yog categorized ua peb hom raws li wavelength: UV-A, UV-B, thiab UV-C.
Txawm hais tias nws tsis pom zoo rau tib neeg pom, lub teeb ultraviolet muaj qhov muaj txiaj ntsig zoo thoob plaws ntau lub tebchaws, thiab qhov tshwm sim ntawm UV LED thev naus laus zis tau nthuav dav ntxiv rau cov ntawv thov no. Niaj hnub no, peb yuav tshuaj xyuas ntau yam kev siv ntawm UV LED teeb.
Dab tsi yog Ultraviolet Teeb?
Nov yog ntau qhov piv txwv ntawm kev siv ntau ntawm UV LED teeb:
Industrial thiab Cosmetic Curing
UV LED teeb siv rau manicure curing
UV curing yog ib txoj hauv kev siv lub teeb ci ultraviolet los kho sai lossis "qhuav" inks, txheej, nplaum, resins, thiab polymers, ua kom lawv tawv tsis muaj kev siv cua sov.
Ntau xyoo dhau los, kev kho tus ntsia thawv pleev xim tau ua nrog cov teeb pom kev tsis zoo ntawm ultraviolet. Hauv xyoo 2013, kev tshawb fawb luam tawm hauv Phau Ntawv Xov Xwm ntawm American Academy of Dermatology qhia tias muaj feem yuav mob qog noj ntshav. Cov kev tshawb fawb tau qhia tias LED teeb muaj kev nyab xeeb dua rau daim ntawv thov no vim lawv txo lub teeb zaus.
Flexfire LED's Ultraviolet LED Sawb Teeb tsim UV-A, daim ntawv tshwj xeeb ntawm UV LED teeb haum rau cov rau tes thiab muaj kev nyab xeeb rau ntawm daim tawv nqaij, ua rau peb lub teeb pom kev zoo tsim cov teeb siv hauv cov khw muag ntsia thawv.
Analytical Instruments
Hneev taw illuminated los ntawm lub teeb ultraviolet ntawm qhov chaw ua txhaum cai.
Lwm qhov kev siv ntawm UV teeb yog kev ua haujlwm ntawm UV tsom teeb teeb kom zoo siab rau cov khoom siv hluav taws xob ntawm cov khoom sib txuas, uas ua rau luminescence thiab ua rau qee cov ntaub ntawv pom rau tib neeg lub qhov muag. Qee yam khoom thiab cov kua dej uas teb rau UV teeb los ntawm kev nthuav tawm fluorescence lossis hloov xim muaj xws li:
Invisible los yog kev ruaj ntseg inks yog siv nyob rau hauv banknotes, cov ntaub ntawv tus kheej, thiab credit cards los xyuas lawv cov qhabnias. Cov inks no suav nrog cov khoom uas fluoresce nyob rau hauv lub teeb ultraviolet.
Cov ntshav thiab cov kua dej hauv lub cev: Qee cov kua dej, xws li qaub ncaug thiab hws, muaj fluorescence nyob rau hauv lub teeb ultraviolet, pab cov kws tshawb fawb txog kev tshawb nrhiav pov thawj ntawm kev ua txhaum cai.
Fibers thiab cov ntaub ntawv: Ntau yam ntuj tsim thiab tsim fibers yuav emit luminescence nyob rau hauv UV teeb, pab nyob rau hauv lub nrhiav tau ntawm ntaub los yog tsoos tsho remnants.
Tshwj xeeb dyes thiab resins: Cov tshuaj no yog siv los txheeb xyuas cov khoom muaj txiaj ntsig lossis cov ntaub ntawv, ua cov cim pom tsuas yog nyob rau hauv UV teeb, yog li pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nyiag lossis tub sab.
Gemology Sector
Ultraviolet (UV) lub teeb yog ib qho cuab yeej tseem ceeb hauv gemology, tso cai rau cov pob zeb thiab pob zeb los txheeb xyuas thiab txheeb xyuas cov gemstones thiab minerals. Cov kws tshaj lij tuaj yeem paub qhov txawv ntawm cov gemstones los ntawm kev tsim los yog tshuaj kho ntau yam los ntawm kev ntsuam xyuas cov fluorescence uas tsim los ntawm cov pob zeb tshwj xeeb, xws li pob zeb diamond thiab rubies. , thaum raug ultraviolet teeb.
Tsis tas li ntawd, cov neeg sau khoom siv nws los tshawb pom thiab faib cov fluorescent minerals xws li calcite thiab fluorite, uas nthuav tawm luminescence nyob rau hauv UV teeb.
Nyob rau hauv UV hluav taws xob, cov zaub mov ua luminous. Cov khoom siv kho mob tau tshuaj tua kab mob siv UV teeb.
Sterilization thiab tshuaj tua kab mob
Ultraviolet-C hluav taws xob yog siv rau hauv cov tshuaj raws li ib tug zoo heev txhais tau tias ntawm tu huab cua thiab dej. Cov txheej txheem no tshwm sim thaum cov hluav taws xob hluav taws xob siab ua rau cov khoom siv caj ces ntawm microbes xws li cov kab mob thiab cov kab mob, tiv thaiv lawv los ntawm kev sib kis rau tib neeg. UV teeb yog siv nyob rau hauv ntau yam sectors, nrog rau kev ua zaub mov thiab kev kho mob.
Qhov tseeb, ib qho laj thawj rau cov khaub ncaws ziab tshav kub yog kom tsis txhob siv lub tshuab ziab khaub ncaws, vim UV hluav taws xob ntuj tua cov kab mob uas tsim kev puas tsuaj rau cov ntaub ntawv.
Sab hauv tsev horticulture
Lub vaj sab hauv tsev nrog cov nroj tsuag cog hauv qab UV teeb.
UV LED teeb yuav tsum muaj rau sab hauv nroog ua liaj ua teb ntawm txiv hmab txiv ntoo, zaub, thiab lwm yam nroj tsuag noj tau. UV LED teeb txhawb kev tsim cov polyphenols, uas paub tias muaj antioxidant thiab tiv thaiv kev laus.
Ib cag ntawm kev ua noj ua haus, UV teeb tau txais txiaj ntsig zoo li cov nroj tsuag tshuaj kho mob los ntawm kev ua kom muaj zog ntawm lawv cov khoom siv tshuaj thiab txhawb kev sib xyaw ntawm cov tshuaj kho mob xws li cannabinoids thiab terpenes.
Cov cwj pwm noj qab haus huv
UV phototherapy yog tam sim no siv los kho cov teeb meem dermatological nrog rau psoriasis thiab vitiligo, nrog rau kev tiv thaiv kev sib kis ntawm qee yam mob qog noj ntshav ntawm daim tawv nqaij. Raws li American Cancer Society, UV teeb, thaum ua ke nrog lwm yam kev kho mob, tau pab qee tus neeg mob ua tiav kev zam mus ntev nyob rau theem pib ntawm tus mob.
Psoriasis, inflammatory dermatosis tshwm sim los ntawm lub cev tsis muaj zog, yog kho nrog UV hluav taws xob, uas txo cov kev tiv thaiv kab mob thiab inflammatory teb.
Risks ntawm UV Radiation
Tsis muaj kev tiv thaiv los ntawm ultraviolet (UV) lub teeb yuav ua rau cov tawv nqaij thiab qhov muag puas, xws li sunburn, laus ntxov ntxov, thiab muaj kev pheej hmoo ntawm mob qog noj ntshav.
Txawm li cas los xij, cov teeb ci ultraviolet siv nyob rau hauv hmo ntuj, hu ua "dub teeb," emit UV-A hluav taws xob, uas zoo ib yam li peb cov UV LED strips. Hom UV-A no muaj lub zog qis dua thiab ntev wavelengths dua li lwm hom UV, qhia tias nws tsis nkag mus rau ntawm daim tawv nqaij lossis ua rau raug mob.
