Cov npe thoob dej yug ntses feem ntau hu rau txhua qhov ntshav - saib LED ultraviolet, tab sis pom cov xim tsis yog qhov ntsuas wavelength. Qhov pom ntau yam yog feem ntau kho raws li txuas mus rau kwv yees li 380 nanometers, thaum ultraviolet nyob hauv qab ntawm thaj tsam pom. A 405-nanometer LED yog ib txwm violet pom lub teeb, txawm tias nws tuaj yeem ua rau muaj fluorescence. Qhov tseeb UV-emitting cov khoom tsim kev ntsuas sib txawv, cov khoom siv, raug, daim ntawv lo, thiab cov lus nug txog kev nyab xeeb. Cov khoom lag luam yuav tsum tshaj tawm lub ncov wavelength thiab spectral tis es tsis txhob cia siab rau lo lus UV.
Peak wavelength ib leeg tseem ua tsis tiav. LED tso zis muaj bandwidth, ntau lawm kam rau ua, tsav- tam sim no dependence, thiab kub dependence. Lub spectroradiometer tuaj yeem qhia tau tias cov khoom puas muaj cov ntsiab lus emission hauv qab ib thaj tsam xaiv thiab nws muaj zog npaum li cas. Ib daim duab normalized qhia cov txheeb ze zoo li tab sis tsis muaj tseeb radiant raug. Rau kev nyab xeeb thiab daim ntawv thov, cov chaw tsim khoom xav tau cov ntaub ntawv xov tooj cua ntsuas raws li qhov kev ncua deb, lub kaum sab xis, tso zis, diffuser, thiab kev khiav hauj lwm - qhov kub thiab txias.
Fluorescence tsis yog pov thawj ntawm ultraviolet tso zis. Ntau cov ntaub ntawv thiab coral pigments fluoresce nyob rau hauv xiav lossis violet lub teeb, thiab cov koob yees duab nrog cov lim dej tuaj yeem ua rau cov nyhuv tshwm sim tshwj xeeb tshaj yog khaus. Qhov no yog kev siv tau zoo, tab sis cov lus piav qhia ntawm cov khoom yuav tsum txheeb xyuas nws li violet lossis xiav excitation thaum uas yog qhov spectrum qhia. Nws yuav tsum tsis txhob hais txog kev ua kom tsis muaj menyuam, kev kho kab mob, kev tsim cov vitamin synthesis, lossis lav cov txiaj ntsig coral. Cov no yog cais cov kab mob lom lossis kev kho mob -style thov kom muaj pov thawj tshwj xeeb.
Photobiological kev nyab xeeb yog ua tiav - khoom lub luag haujlwm. IEC 62471-6: 2022 muab kev nyab xeeb rau cov khoom siv hluav taws xob ultraviolet, suav nrog cov khoom siv UV LED, nrog rau kev ntsuas, pab pawg muaj kev pheej hmoo, cov ntaub ntawv siv, thiab daim ntawv lo. IEC 62471-7: 2023 hais txog qhov chaw thiab luminaires feem ntau emitting pom hluav taws xob. Txoj kev siv tau nyob ntawm qhov khoom tiag tiag thiab kev ua lag luam. Daim ntawv tshaj tawm pob LED liab qab tsis tuaj yeem npog tag nrho cov khoom siv vim tias optics, tsav tsheb, kev ncua deb, vaj tse, thiab kev nkag mus saib tau tuaj yeem hloov qhov raug.
Geometry tseem ceeb heev ntawm luv wavelengths. Lub teeb pom kev zoo saib ncaj qha los ntawm qhov sib ze yog txawv ntawm lub teeb diffuse mounted saum dej. Reflective hau, polished hlau, thiab cov chaw ntub dej tuaj yeem tsim txoj hauv kev uas tsis xav txog. Txheeb xyuas qhov kev teeb tsa, kev saib xyuas, kev yees duab, thiab kev nkag mus rau menyuam yaus, tsis yog saib pem hauv ntej xwb. Cov lus qhia yuav tsum ceeb toom tiv thaiv kev ntsia mus rau hauv qhov chaw, txheeb xyuas qhov kev taw qhia thiab kev ncua deb, thiab hais tias yuav tsum muaj cov ntaub thaiv npog lossis npog.
Cov ntaub ntawv kuj teb txawv. Qee cov yas, cov nplaum, cov tsho cable, cov khoom sib txuas, cov coatings, thiab cov diffusers tuaj yeem ua kom tsis muaj xim lossis poob cov khoom siv hauv qab UV raug. Lub tsev yuav tiv thaiv tus neeg siv thaum maj mam degrading nws tus kheej. Kev tsim nyog yuav tsum muaj xws li kev sib kis ntawm optical, hloov xim, tawg, adhesion, sealing kev ua tau zoo, thiab hluav taws xob ncaj ncees tom qab raug cuam tshuam. Ib qho kev hloov pauv uas zoo ib yam hauv lub teeb dawb yuav muaj qhov sib txawv luv luv -wavelength durability.
Kev tswj hwm kev tsim khoom yuav tsum kho lub wavelength raws li ib qho tseem ceeb yam ntxwv. Qhia meej txog qhov pom zoo ntawm LED, rau hauv lossis kam rau ua, tsav tam sim no, optic, diffuser, thiab firmware txwv. Tshuaj ntsuam cov khoom tuaj thiab cov chav ua tiav nrog cov khoom tsim nyog. Yog tias tus neeg muag khoom hloov lub violet emitter nrog lub luv luv - cov khoom siv wavelength, qhov kev thov kev lag luam thiab kev ntsuas kev nyab xeeb tuaj yeem hloov pauv. Cov qauv golden thiab cov ntaub ntawv spectrum muaj txiaj ntsig zoo dua li kev tshuaj xyuas kom zoo nkauj ntawm seb cov LEDs zoo li ntshav.
Daim ntawv teev npe muaj lub luag haujlwm siv cov lus tseeb: violet LEDs nrog lub ntsuas peak nyob ze ntawm qhov teev wavelength, tsim los txhim kho fluorescence pom, nrog cov zis thiab ntsuas cov xwm txheej tau teev tseg. Yog tias cov khoom tsim tawm tiag tiag ultraviolet, ua kom tiav cov kev nyab xeeb, kev tswj hwm, cov khoom siv, thiab cov ntawv sau ua haujlwm ua ntej kev nce qib. Lub teeb luv luv - wavelength teeb tuaj yeem yog qhov muaj txiaj ntsig thoob dej yug ntses, tab sis kev ntseeg tau pib los ntawm kev tso npe ntawm qhov khoom siv tiag tiag tawm thiab tsis kam tig fluorescence mus rau kev noj qab haus huv, tsis muaj menyuam, lossis kev thov kev loj hlob thoob ntiaj teb.
Cov ntaub ntawv yuav tsum cais peb cov lus nug: dab tsi wavelengths yog emissions, dab tsi pom kev tshwm sim, thiab dab tsi raug tswj yuav tsum tau. Muab cov spectrum thiab ntsuas tej yam kev mob rau hauv cov ntaub ntawv technical; ua kom meej meej - siv thiab ceeb toom cov lus hauv phau ntawv; thiab khaws cov ntawv thov kev lag luam e-lag luam nrog ob qho tib si. Cov neeg siv khoom xav tau cov lus zoo tib yam yog li cov neeg sawv cev tsis qhia cov neeg yuav khoom tias lub violet channel tshuaj tua kab mob los yog hloov cov cuab yeej kho mob. Yog hais tias lub wavelength los yog cov zis hloov pauv tau qhia, tshuaj xyuas qhov kev ntsuas kev nyab xeeb ntawm qhov muag, cov khoom siv sib xws, cov ntaub ntawv ua raws, ntim, app daim ntawv lo, thiab yees duab ua ke. Luv-wavelength raug tsis yog kev tshawb fawb polish; nws tiv thaiv lub sij hawm ua lag luam xws li los ntawm kev nthuav tawm cov khoom lag luam thov kev ua haujlwm thiab kev pheej hmoo profile.
Cov cuab yeej ntsuas yuav tsum muaj qhov tsim nyog spectral rhiab heev. Lub lux meter dav dav yog qhov hnyav rau tib neeg lub zeem muag thiab tsis zoo rau kev ntsuas qhov pom ntawm ultraviolet radiant. Qee qhov quantum sensors kuj muaj qhov txwv lossis wavelength - nyob ntawm cov lus teb sab nraum lawv cov calibrated ntau. Siv cov khoom tsim thiab calibrated rau qhov kom muaj nuj nqis, thiab cov ntaub ntawv tsis meej. Cov ntxaij lim dej kho qhov muag, dej, iav, thiab acrylic tuaj yeem ua rau luv luv wavelengths txawv, tab sis lub hau yuav tsum tsis txhob raug kho raws li cov cuab yeej kev nyab xeeb tshwj tsis yog tias nws cov khoom, tuab, kev laus, geometry, thiab kev ncaj ncees raug txheeb xyuas. Rau cov neeg yuav khoom lag luam, thov kom ua tiav cov ntaub ntawv hauv chav kuaj, cov duab kos duab, ntsuas qhov deb, nkag tau mus rau emission, kev faib cov kev pheej hmoo, cov lus ceeb toom, thiab cov ntaub ntawv pov thawj pom zoo. Paub meej tias tus qauv sim suav nrog tib lub diffuser thiab firmware txwv kev tsim khoom. Yog tias daim ntawv teev npe siv UV ua cov ntsiab lus tshawb fawb rau violet-tsuas yog cov khoom, kho nws; kev tshawb nrhiav pom tsis yog qhia txog cov khoom tsis tseeb technically.
Siv cov ntaub ntawv wavelength ua ntej terminology, kev soj ntsuam kev nyab xeeb ua ntej kev nce qib, thiab cov hom phiaj meej -siv cov lus thov ua ntej kev cog lus lom neeg. Qhov kev qhuab qhia ntawd cia cov yam ntxwv fluorescence nyob twj ywm txaus nyiam yam tsis muaj kev dag ntxias. Ua ntej tso tawm, txheeb xyuas cov khoom tsim tawm, kev nkag mus tau yooj yim, cov khoom siv kho qhov muag, daim ntawv lo app, cov lus thawv, thiab cov neeg siv khoom- tsab ntawv pabcuam tawm tsam tib qhov kev tsim kho pom zoo. Precision ntawm txhua qhov touchpoint ua kom muaj txiaj ntsig zoo ntawm violet los ntawm kev qhia tsis tseeb raws li kev kho mob ultraviolet. Khaws qhov ntsuas spectrum nrog txhua tus qauv hloov kho.
