Tua kab mob nrog UVC LEDs!
Tib neeg tawm tsam cov kab mob tau mus ntev heev. Cov tshuaj tua kab mob tsuas yog txwv rau lawv lub peev xwm los tua vim cov kab mob, xws li cov kab mob thiab cov kab mob, tuaj yeem tiv taus. Ultraviolet (UV) lub teeb yog ib txoj hauv kev zoo dua ntawm kev tua kab mob thiab ua kom tsis muaj dej, huab cua thiab qhov chaw, ua rau nws muaj peev xwm tiv thaiv tus kabmob coronavirus.
Txhawm rau tshuaj tua kab mob khaub ncaws tiv thaiv ntawm cov neeg ua haujlwm kho mob hauv Tsev Kho Mob Wuhan Huoshenshan txhawm rau tiv thaiv kev kis tus kabmob tshiab mus rau sab nraud, lub tsev pheebsuab tua kab mob nrog UVC LEDs tau tsim hauv zos, uas yog hom tshuaj tua kab mob tshiab. Hauv ib chav nrog thaj tsam ntawm 1.5mx 0.75m x 2m, ntau txheej hluavtaws fiber ntau phab ntsa tau teeb tsa, thiab cov nplaim hluav taws xob ntawm lub qab nthab, phab ntsa thiab hauv pem teb yog nruab nrog UVC emitters los ntawm Asmeskas tus neeg muag khoom Bolb. . Thaum lub sijhawm 30- cov txheej txheem tshuaj tua kab mob thib ob, UVC LED dosed ntawm 6mJ / cm2 thiab qhov ci ntsa iab yog 200μW / cm2. Lub 265 mus rau 280nm wavelength ntawm lub teeb rhuav tshem cov ntaub ntawv caj ces, yog li txiav tawm kev kis tus kab mob lossis tiv thaiv nws los ntawm kev kis mus rau lwm lub hlwb.
Artificial UV qhov chaw
Mercury-raws li cov hluav taws xob hluav taws xob tau ntev tau siv los tsim lub teeb UV, xws li roj siv hluav taws xob qis thiab nruab nrab-siab mercury-vapor (Hg) teeb, uas tsim lub teeb nyob rau hauv 185 mus rau 405nm spectrum los ntawm cov pa tawm UV teeb. Glow tawm kuj tseem siv tau los tsim lub teeb ultraviolet nyob rau hauv spectral ntau ntawm 185 mus rau 405 nm los ntawm txoj kev ntawm ultraviolet txias cathode hlab (UV-CCL los yog UV teeb).
UV LEDs emit UV rays nyob rau hauv spectral ntau ntawm 227 mus rau 405 nm los ntawm electroluminescence. Thaum UVC LEDs tau siv, lub wavelengths yog luv luv (nruab nrab ntawm 260 thiab 270nm) los muab cov txiaj ntsig zoo tshaj plaws. Daim duab 1 qhia txog qhov piv txwv ntawm Cryptosporidium, ib qho kab mob uas tshwj xeeb tshaj yog kis tau rau hauv cov dej haus tsis huv. Lwm cov kab mob, kab mob thiab kab mob muaj cov yam ntxwv zoo sib xws.
LEDs kuj muab cov txiaj ntsig zoo ruaj khov spectral tso tawm nyob rau hauv cov xwm txheej kub tshwj xeeb nrog rau qhov tsis muaj qhov txwv tsis pub hloov mus, ua rau lawv zoo tagnrho rau cov kev daws teeb meem ntawm lub xov tooj uas xav tau lub teeb pom kev zoo yam tsis muaj kev ncua.
Ntau riam phom
Ultraviolet lub teeb muaj lub wavelength ntawm 100 mus rau 400 nm thiab tsis pom ntawm qhov muag liab qab. Lawv cov zaus tau muab faib ua UVA, UVB thiab UVC bands, thiab cov kab sib txawv muaj qhov sib txawv ntawm cov kab mob.
LEDs tso cai rau peb kom txiav txim siab qhov wavelength xaiv. Piv nrog UVB thiab UVC rays, UVA LEDs nrog wavelengths ntawm 315 mus rau 400nm muaj zog nkag mus rau hauv cov ntaub so ntswg dispersed xws li tib neeg cov tawv nqaij. UVA LEDs tuaj yeem siv rau hauv thaj chaw xws li kev kho hniav thiab tshuaj pleev ib ce, xws li tanning studios thiab nail studios. Hauv kev lag luam, UVA LEDs yog siv los kho cov resins, adhesives thiab xim.
UVB LED rays muaj wavelengths ntawm 280 txog 315nm thiab muaj qhov tsis muaj zog nkag mus rau cov ntaub so ntswg tawg, tab sis lawv muaj ntau dua. UVB rays txhawb kev tsim cov vitamin D nyob rau hauv lub cev, uas yog vim li cas UVB LEDs mas siv nyob rau hauv phototherapy thiab dermatological kev kho mob.
Tsis muaj kev tiv thaiv UVC rays
Lub teeb hluav taws xob siab los ntawm UVC LEDs tau tawg zuj zus ntxiv hauv cov ntaub so ntswg lom. Cov rays no, uas muaj wavelengths ntawm 100 txog 280 nm, tsis nkag mus rau cov ntaub so ntswg tshwj xeeb, tab sis tuaj yeem hlawv cov tawv nqaij tsis muaj kev tiv thaiv. Txij li cov txheej txheej ozone nyob hauv lub ntiaj teb huab cua nqus cov hnub ci ntuj UVC hluav taws xob, tsis muaj dab tsi hauv ntiaj teb tau tsim cov txheej txheem tiv thaiv UVC rays, thiab tsis muaj kab mob thiab kab mob. Qhov tsis zoo no ua rau cov khoom siv hluav taws xob UVC teeb irradiation yog ib txoj hauv kev zoo tshwj xeeb ntawm kev ua kom tsis muaj menyuam thiab tshuaj tua kab mob.

UVC LEDs hauv kev xyaum
Txhua kab kab mob teb txawv rau UVC hluav taws xob, uas yog vim li cas qhov kev siv hluav taws xob ntawm cov hluav taws xob yuav tsum tau hloov mus rau qhov xav tau kev ploj tuag, uas yog tus naj npawb ntawm cov kab mob tua. Qhov kev siv ntawm UV hluav taws xob yog inversely proportional rau lub square ntawm qhov kev ncua deb, uas txhais tau hais tias UV hluav taws xob poob nws cov hauj lwm sai li sai tau raws li qhov kev ncua deb ntawm cov hluav taws xob qhov chaw nce, uas yog vim li cas cov khoom uas yuav tsum tau sterilized yuav tsum nyob ze li sai tau. tus emitter.
Cov kab mob, suav nrog tus kabmob tshiab, feem ntau yog huab cua, yog li UVC LEDs tau pom zoo siv rau hauv cov tshuab cua txias. Ntxiv nrog rau qhov xav tau extinction npaum li cas, huab cua txaus thiab huab cua ntws geometry yuav tsum tau xav txog.
Ultraviolet lub teeb nrog lub wavelength ntawm 254nm tau pom tias muaj txiaj ntsig tshwj xeeb ntawm kev tua cov kab mob, txawm hais tias nws tuaj yeem tsim teeb meem rau daim tawv nqaij thiab qhov muag thaum thov ncaj qha. Ntawm qhov tod tes, "dav-ultraviolet" lub teeb (207 mus rau 222 nm) tuaj yeem ua kom dav dav rau cov kab mob hauv huab cua yam tsis muaj kev puas tsuaj rau tib neeg cov ntaub so ntswg.
Disinfect qhov chaw
Lwm cov kab mob thiab kab mob tuaj yeem kis tau los ntawm qhov chaw, suav nrog mob khaub thuas, norovirus, rotavirus, streptococcus, thiab salmonella. Yog tias qhov chaw loj dua yuav tsum tau ua kom huv, Lextar lub zog qis PU35CL1.0 UVC LED yuav yog cov khoom tsim nyog nrog cov zis ntawm 2-4mW thiab 20mA; Nws kuj tseem tuaj yeem siv los pasteurize dej haus, ntim cov khoom noj Antibacterial, thiab ntxuav cov txhuam hniav.
Rau kev teeb tsa me me, Bolb qhia txog lub zog nruab nrab lub zog S3535-DR100-W272-P40 UVC LEDs ntsuas 3.5 x 3.5 x 0.9mm3. Nrog rau DC lub zog noj ntawm 40mW thiab tam sim no tsuas yog 100mA, nws sawv tawm nrog lub zog siv hluav taws xob qis tshaj plaws thiab cov hluav taws xob qis tshaj plaws hauv ntiaj teb.
Hauv ntu hluav taws xob siab, Bolb tau qhia txog S6060-DR250-W272-P100 UVC LED, cov khoom siv muaj zog tshaj plaws nrog lub zog DC ntawm 100mW ntawm 250mA.
Bolb's UVC LEDs yog qhov tshwj xeeb tshaj yog tsim rau kev kho dej haus thiab tshuaj tua kab mob hauv cov pas dej da dej lossis RVs, nrog rau cov ntawv thov siv hluav taws xob siv hluav taws xob nruj dua (W / m2), xws li cov tshuab lim dej, cua purifiers, cov thawv tshuaj tua kab mob thiab lub tshuab nqus tsev vacuum.
Daim duab 2: High Output - Bolb's High Power UVC LEDs muaj lub zog noj ntawm 100mW ntawm 250mA (nrog thiab tsis txuas)
Cov txheej txheem xaiv rau UV LEDs
Ib qho kev xaiv tseem ceeb rau UV LEDs yog lub kaum sab xis, uas yuav tsum tau muaj nyob rau hauv qee qhov kev siv. Bolb's UVC LEDs muaj lub kaum sab xis ntawm 150 degree thiab tuaj yeem tsom mus ntxiv siv Ledil's lo ntsiab muag raws li xav tau. Vim tias qhov no txo qhov saum npoo yog irradiated, nws kuj nce lub zog radiant ib square meter, uas txhais tau hais tias tsawg dua lub sij hawm raug yuav tsum tau thaum siv tib lub zog tso zis. Qhov sib txawv UV lo ntsiab muag nrog cov iav sib xws tso cai yooj yim hloov ntawm irradiance tso zis rau ntau lub hom phiaj. Rau UV lo ntsiab muag, Ledil siv cov qib tshwj xeeb ntawm silicone uas tshwj xeeb tshaj yog sib xws nrog UVC wavelengths, nrog rau cov iav txhuas uas muaj kev cuam tshuam siab rau txhua qhov UV wavelengths, tshwj xeeb tshaj yog rau kev siv tshuaj tua kab mob.
Lwm yam kev xaiv rau UV LEDs suav nrog lub teb chaws UV qauv, kev cuam tshuam ntawm cov khoom sib txawv (Daim duab 3), kev tswj xyuas thermal, tsav tsheb, kev siv hluav taws xob, thiab txoj cai rov qab square, uas txiav txim siab yuav ua li cas beam siv tsawg zuj zus thaum nws txav deb ntawm qhov chaw.
Daim duab 3: Cov ntaub ntawv sib txawv muaj ntau theem ntawm kev cuam tshuam UV uas yuav tsum tau coj mus rau hauv tus account thaum lub sijhawm tsim.
Bolb's Blazar nto emitters ua tau raws li ntau yam ntawm cov qauv no. Qhov no UVC module muaj 25 LEDs (5 × 5) thiab 55 degree reflector kom ua tiav 2W cov khoom siv tau zoo thaum lub zog siv tsuas yog 1.25A.
Tam sim no tsim Multi-UV LED khoom. Lawv siv dual-wavelength chips uas xa ntau lub UV wavelengths, xws li UVA thiab UVC, ua rau lawv muaj ntau yam riam phom tiv thaiv kab mob, kab mob, thiab lwm yam kab mob.
