Electromagnetic hluav taws xob nrog lub wavelength luv dua li pom lub teeb yog hu ua ultraviolet (UV) lub teeb. UV teeb tau muab faib ua peb pawg raws li nws qhov wavelength:UV-A, UV-B, thiab UV-C.
Ultraviolet lub teeb muaj kev siv tseem ceeb hauv ntau qhov kev lag luam sib txawv, txawm tias nws tsis pom ntawm tib neeg lub qhov muag. Nrog rau kev tsim ntawm UV LED teeb, cov kev siv no tau loj hlob ntau dua. Peb mam li tham txog ob peb daim ntawv thov UV LED hnub no.
Ultraviolet teeb: Dab tsi yog lawv?
Ib hom hluav taws xob tsis pom kev, lossis lub teeb lub zog, ultraviolet (UV) lub teeb muaj ntau zaus thiab lub zog ntau dua li pom lub teeb. UV teeb yog ib zaug hu ua "tshuaj rays" thaum nws tau pom thawj zaug nyob rau hauv lub xyoo pua 19th vim hais tias nws muaj peev xwm hloov tau qee qhov sib txuas ntawm qib molecular.
Tsis muaj teeb pom kev lag luam UV LED kom txog rau thaum xyoo 2010. Tab sis raws li kev siv thev naus laus zis thev naus laus zis, UV LED teeb tau nkag mus rau hauv kev ua lag luam thiab tau pib siv ntau yam, suav nrog kev kho mob thiab tshuaj pleev ib ce.
Muaj kev siv tshwj xeeb rau txhua qhov ntawm ntau lub teeb UV zaus hauv lwm qhov kev lag luam. Piv txwv li, UV-A yog siv rau kev tu ntsia thawv, tab sis UV-B thiab UV-C yog siv rau kev kho mob lub teeb thiab ua kom tsis muaj menyuam.
Nov yog qee qhov kev siv ntau heev rau UV LED teeb:
Kev kho mob hauv kev lag luam thiab tshuaj pleev ib ce
Cov txheej txheem ntawm UV kho yog siv UV lub teeb kom "qhuav" los yog kho inks, coatings, nplaum, resins, thiab polymers kom lawv tawv yam tsis tas yuav tsum tau cua sov.
Yav dhau los, unregulated UV teeb tau siv los kho tus ntsia thawv polish. Txawm li cas los xij, qhov muaj feem yuav mob qog noj ntshav ntawm daim tawv nqaij tau sau tseg hauv kev tshawb fawb xyoo 2013 uas tau luam tawm hauv Phau Ntawv Xov Xwm ntawm American Academy of Dermatology. Raws li kev tshawb fawb, LED teeb 'txo lub teeb zaus ua rau lawv muaj kev nyab xeeb dua rau kev siv no.
Flexfire LED's Ultraviolet LED Sawb Teeb yog qhov zoo tshaj plaws rau kev tsim cov teeb siv hauv cov khw muag ntsia thawv txij li lawv emit UV-A, uas tsuas yog hom UV LED teeb rau cov rau tes thiab nyab xeeb rau ntawm daim tawv nqaij.
Cov cuab yeej tsom xam
Kev siv lub teeb tsom teeb UV, uas ua rau cov khoom siv hluav taws xob zoo siab hauv kev kuaj xyuas thiab ua rau lawv ci, yog lwm daim ntawv thov rau UV teeb uas ua rau qee qhov sib txuas pom ntawm qhov muag liab qab. Cov hauv qab no yog qee cov ntaub ntawv thiab cov kua uas hloov xim lossis tawm fluorescence los teb rau lub teeb ultraviolet:
Invisible los yog kev ruaj ntseg inks: Cov no yog siv los txheeb xyuas qhov tseeb ntawm daim ntawv banknotes, cov ntaub ntawv qhia tus kheej, thiab credit cards. Nyob rau hauv lub teeb UV, qee yam khoom hauv cov inks ci ntsa iab.
Cov ntshav thiab cov kua dej hauv lub cev: Qee cov kua dej hauv lub cev, xws li hws thiab qaub ncaug, ci ntsa iab thaum raug ultraviolet lub teeb, uas pab cov kws tshawb fawb hauv kev tshawb nrhiav pov thawj ntawm kev ua txhaum cai.
Cov ntaub ntawv thiab fibers: Ntau cov hluavtaws thiab cov fibers ntuj tuaj yeem ci thaum raug UV teeb, uas ua rau nws yooj yim rau pom cov khoom seem ntawm cov khaub ncaws lossis ntaub.
Txhawm rau pab txheeb xyuas cov tub sab nyiag lossis kev nyiag khoom, cov xim tshwj xeeb thiab cov resins yog siv los ua cov khoom muaj txiaj ntsig lossis cov ntaub ntawv uas tsuas pom nyob rau hauv lub teeb ultraviolet.
Field of Gemology
Lub peev xwm los lees paub thiab lees paub lub pov haum thiab cov zaub mov yog ua tau los ntawm ultraviolet (UV) lub teeb, uas yog ib qho tseem ceeb hauv gemology.Los ntawm kev saib xyuas cov fluorescence uas qee lub pob zeb, xws li pob zeb diamond thiab rubies, emanate thaum raug ultraviolet lub teeb, cov kws tshaj lij tuaj yeem sib txawv cov pob zeb ntuj los ntawm ib qho khoom tsim los yog kev kho mob.
Nws kuj yog siv los ntawm cov neeg sau kom paub thiab txheeb xyuas cov fluorescent minerals uas ci thaum raug ultraviolet lub teeb, xws li fluorite thiab calcite.
Disinfection thiab Sterilization
UV-C hluav taws xob yog siv nyob rau hauv kev kho mob thiab yog ib qho kev xaiv zoo rau purifying dej thiab cua. Cov hluav taws xob siab ua rau cov kab mob xws li cov kab mob thiab cov kab mob plam lawv cov khoom siv caj ces, uas txwv tsis pub lawv kis rau tib neeg. UV hluav taws xob yog siv rau hom tshuaj tua kab mob no hauv ntau yam kev lag luam, suav nrog kev ua zaub mov thiab kev kho mob.
Qhov tseeb, qhov no yog ib qho laj thawj uas nws tau qhia kom ziab khaub ncaws nyob rau hauv lub hnub-natural UV hluav taws xob tshem tawm cov kab mob txaus ntshai ntawm cov khaub ncaws ntxiv rau kom tsis txhob muaj zog- tshaib plab.
Sab hauv vaj
Thaum cog txiv hmab txiv ntoo, zaub, thiab lwm yam nroj tsuag rau tib neeg noj sab hauv,UV LED teebyog qhov tseem ceeb. Polyphenols, uas xav tias muaj kev tiv thaiv kev laus thiab kev tiv thaiv antioxidant, yog tsim ntau dua nyob rau hauv UV LED teeb pom kev zoo.
UV teeb muaj txiaj ntsig zoo rau cov resin- tsim cov nroj tsuag, zoo li cov tshuaj maj kho mob, ntxiv rau kev cog qoob loo vim tias lawv txhawb kev txhim kho cov tshuaj kho mob xws li terpenes thiab cannabinoids thiab ua kom cov txiaj ntsig zoo ntawm lawv cov tshuaj.
Cov Khoom Ntawm Kev Noj Qab Haus Huv
Niaj hnub no, UV phototherapy yog siv los kho vitiligo thiab psoriasis, nrog rau kom tsis txhob muaj kev loj hlob ntawm ib hom mob qog noj ntshav. Thaum siv nrog rau lwm yam kev kho mob, UV teeb tau pab ntau tus neeg mob nyob rau theem pib ntawm tus kab mob ua tiav ntev - lub sij hawm tshem tawm, raws li American Cancer Society.
Lub cev tiv thaiv kab mob yog suppressed thiab inflammatory kev tshwm sim yog txo los ntawm UV teeb nyob rau hauv psoriasis, ib tug inflammatory txheej txheem ntawm daim tawv nqaij tshwm sim los ntawm lub cev tsis muaj zog.
UV Light's Dangers
Tsis muaj kev tiv thaiv ultraviolet (UV) lub teeb pom kev tuaj yeem ua mob rau ntawm daim tawv nqaij thiab qhov muag ntawm ntau txoj hauv kev, ua rau muaj kev pheej hmoo ntawm kev mob qog noj ntshav, sunburn, thiab kev laus ntxov ntxov.
Tab sis zoo li peb cov UV LED strips, "dub teeb," lossis UV teeb siv nyob rau hauv nightclubs, emit UV-Ib hluav taws xob. Vim tias hom UV no-A muaj lub zog ntev dua thiab lub zog tsawg dua li lwm hom UV, nws tsis tuaj yeem nkag mus rau ntawm daim tawv nqaij lossis ua mob rau nws.
UV Light Applications 'Qhov tseem ceeb hauv lub neej txhua hnub
UV teeb muaj ntau yam kev siv, suav nrog kev tshawb nrhiav kev tshawb fawb, tshuaj tua kab mob, thiab tshuaj pleev ib ce thiab tshuaj.UV LED teebmuaj cov ntawv thov hauv lub neej niaj hnub, txawm tias peb tau hais txog ob peb lub hom phiaj tseem ceeb, xws li kev ua kom tsis muaj menyuam thiab kev tu tawv nqaij.
UV lub teeb yog qhov tseem ceeb rau kev tswj cov kab tsuag, kev txuag zaub mov, kev kho hniav, thiab kev lim dej hauv pas dej ua ke thiab kev kho mob yam tsis tas siv tshuaj. Cov ntawv thov no txhim kho cov khoom tsim tau thoob plaws ntau qhov chaw thiab txhawb nqa peb txoj kev noj qab haus huv thiab kev noj qab haus huv.
