Kukula kwa UV Leds Pansi pa Mliri

Matenda okhudzana ndi thanzi ndi madzi amawonongera dziko mabiliyoni a madola pachaka komanso miyoyo zikwizikwi chaka chilichonse. Njira imodzi yofunika yodzitetezera ndiyo kutsekereza, komwe kungatheke pogwiritsa ntchito njira zosiyanasiyana, kuphatikizapo kuyatsa kwa kuwala kwa ultraviolet (UV). Popeza njira zoyenera zoyezera zimatha kuyimitsa kufala kwa matenda opatsirana, izi zakhala zofunikira kwambiri chifukwa cha mliri wapadziko lonse lapansi wa coronavirus.

Poyerekeza ndi magetsi a semiconductor, magwero apano monga mababu a mercury ndi ochulukirapo, owopsa, ndipo ali ndi zosankha zochepa zogwiritsa ntchito.

Kodi Chiyani Ndi ma UV LED ?

Ma UV-LED ndi ma LED omwe amapanga kuwala kwa UV ndi kutalika kwa 400 nm kapena kuchepera. Amapatulidwa kukhala ma LED akuya a ultraviolet (DUV-LEDs), omwe amakhala ndi utali wotulutsa pafupifupi 200-3 2 0 nm, ndi pafupi ndi ultraviolet kuwala-emitting diodes (NUV-LEDs), amene ali ndi utali wavelength pafupifupi 3 2 0-400 nm.

Ma UV-LED akulonjeza ofuna ntchito zingapo, kuphatikiza kusintha nyali za UV, magwero a kuwala kwa fulorosenti kuti awonetse ndi kuyatsa, magwero abwino owunikira ma microscope ndi zida zowunikira,
magwero kuwala kwa mankhwala chisangalalo 4 amagwiritsidwa ntchito mu biotechnology, mankhwala, ndi machiritso a utomoni, zowunikira zowunikira zowunikira zowunikira zomwe zimagwiritsidwa ntchito pozindikiritsa ndalama, tchipisi ta DNA, kuyang'anira zachilengedwe, ndi magwero aukhondo amagetsi ophera tizilombo toyambitsa matenda ndi kulera.

Kupanga kwa Uv Leds

Ngakhale mliri womwe ukupitilira, kupha tizilombo toyambitsa matenda ndi njira yofunika kwambiri paumoyo wa anthu poletsa kufalitsa matenda ambiri opatsirana. Mosakayikira pali chidwi chopanga ukadaulo womwe ungalole kupha tizilombo toyambitsa matenda pafupipafupi, mopitilira muyeso, makamaka m'malo omwe anthu amawachezera kwambiri, chifukwa cha chidziwitso chaposachedwa cha kukhudzana kwambiri komanso kusewera m'nyumba pakufalitsa kachilomboka.

Ngakhale amagwira ntchito bwino, mankhwala omwe amagwira ntchito m'mankhwala ophera tizilombo toyambitsa matenda m'malo azachipatala ndi ma labotale amabweretsa zovuta zanyengo, thanzi la anthu, komanso zomangamanga zomwe zimapangitsa kuti kufalikira kwawo kukhale kovuta. Kuphatikiza apo, mphamvu ya mankhwala ophera tizilombo amatha kusiyanasiyana kutengera wogwiritsa ntchito komanso momwe amatsata mosamala njira zoyeretsera zomwe zimabwerezedwa. M'malo mwake, ma radiation a ultraviolet (UV) akhala akugwiritsidwa ntchito kwambiri poyambitsa tizilombo tambirimbiri, kuphatikiza ma virus. Kuwala kwa Ultraviolet kumatha kupanga makina opangira majeremusi obwerezabwereza.

Chiyambi cha UV LED diode imapereka mulingo womwewo wa decontamination ngati nyali zachikhalidwe za mercury, koma ndi zabwino zingapo, kuphatikiza kuphweka kwa retrofit mumitundu yosiyanasiyana yanthawi zonse yowunikira, yokhala ndi mphamvu zowonjezera zopha tizilombo.

Kuchita bwino kwa UV pakuyeretsa kumawonetsedwa ndi njira yake yowongoka. Pomwe maziko oyandikana nawo a thymine (kapena zoyambira za uracil pa nkhani ya RNA) amavutika ndi dimerization, zomwe zimasokoneza kapangidwe ka nucleotide ndikupanga "zotchinga" mu kubwereza kwa ma genome, maziko oyandikana ndi ma nucleotide mu DNA ndi RNA mwapadera amayamwa mafoto a UV.

Ofufuza adawonetsa mphamvu ya antiviral ya a Uv di miza poyambitsa ma virus awiri: Coronavirus 229E (hCoV-229E) wamunthu wanyengo ndi mtundu woyamba wa HIV (HIV-1). Ofufuza akuwonetsa kuchepetsedwa kwakukulu kwa kubwereza kwa ma virus mkati mwa masekondi pambuyo pakuwonekera kwa UV-LED potengera zochitika za chilengedwe za kufalikira kwa ma virus (mwachitsanzo, kuyetsemula, chifuwa, madontho amagazi) pogwiritsa ntchito njira zobalalitsira madontho.

Kafukufuku wathu amathandizira ku chidziwitso chogwiritsa ntchito ma UV-LED kuyeretsa malo omwe anthu ambiri amalumikizana nawo. Ma UV-LED amayimira chitetezo chowonjezera, chothandiza kwambiri polimbana ndi kufalikira kwa tizilombo toyambitsa matenda chifukwa ndi otsika mtengo komanso osavuta kuyiyika m'malo osiyanasiyana omwe alipo, makamaka pa nthawi ya mliri wapakhungu.

Zofunikira za UV-LED

Ma LED asanu ndi anayi a 275 nm mumtundu wa 3 3 ndi ma LED makumi awiri a 380 nm mu 4 5 array anali ndi ma seti awiri a UV-LED omwe adaperekedwa. Mtunda pakati pa ma LED ndi zitsanzo zowonekera unali pafupi masentimita 5, ndipo kuwala kwa UV kuchokera kumagulu osiyanasiyana kunayambira 0.4 mpaka 0.6 mW/cm2.

Kutalika kwakukulu kwa ma radiation kunali masekondi a 30, ndipo magulu ophatikizana adapereka mlingo wokwanira ku zitsanzo za radioactive kuyambira 8 mJ/cm2 mpaka 20 mJ/cm2. Dera lonse lowala la chipangizocho linali pafupifupi 10 cm ndi 20 cm, kapena 200 cm2, lalikulu kwambiri kuposa chitsanzo choyatsidwa, ndipo idalandira mulingo wa aquifer wa 1.6 J mpaka 4 J.

Zotsatira Zakufufuza Kwachitukuko cha UV LED Pansi pa Mliri

Uv di miza   adawonetsedwa m'maphunzirowa kukhala othandiza poyambitsa mabakiteriya osamva UV, HIV-1, ndi Coronavirus 229E yamunthu. Pankhani ya coronavirus yamunthu, tidawona kuchepetsedwa kwa ma virus mpaka 5.8-Log. Popeza kuwonongeka kwa RNA ndi njira yeniyeni yochotsera ndi kuwala kwa UV komanso momwe-229E ilili kachilombo ka RNA, ofufuza amalosera kuchepetsedwa kofanana kwa matenda pambuyo pa UV.

Komabe, sanaunike mwachindunji ngati kuchepetsedwa uku kwa kubwereza kwa hCoV-229E kumagwirizana ndi kuchepetsedwa kofananako kwa matenda. Ofufuza akuchenjeza kuti zotsatira zathu zitha kugwiritsidwa ntchito mwachindunji kuti ziwone momwe ma virus osaphimbidwa amagwirira ntchito chifukwa nthawi zambiri amakhala olimba ku UV kuposa ma virus ophimbidwa.

Mu kafukufukuyu, kafukufuku akuwonetsa kuti ma virus omwe tidasankha anali ma virus ophimbidwa, osankhidwa kuti awone kusiyana kulikonse komwe kungatheke pakulandila kwa UV chifukwa cha kutalika kwa ma virus.

Kukhazikitsidwa kwa B. ma pumilus spores, omwe amadziwika kuti ali ndi mulingo wambiri wa UV osalimba, adawonetsedwa m'mayesero athu. Ofufuza akuti uwu ukhoza kukhala umboni woyamba kuti ma virus osaphimbidwa amatha kutsekedwa ndi kuwala kwa UV. Zapangidwa kuti zigwiritse ntchito B. pumilus spores ngati choyimira poyesa kuyesa kutsekedwa kwa rotavirus yamunthu yomwe sinaphimbidwe ndi ma radiation a UV.

Kodi Mungagule Kuti UV Wanu Wa LED Kuchokera?

Ndi kupanga kwathunthu, kukhazikika komanso kudalirika, komanso ndalama zotsika mtengo, Malingaliro a kampani Tianhui Electronics   wakhala akugwira ntchito mu Njira ya UV LED   Malo. UV   L ed opanga   bwerani mu UVA, UVB, ndi UVC wavelengths. Kutengera mitundu yosiyanasiyana ya UV, mitundu yambiri ya UV LED diode   zilipo, monga UV LED   misampha ya udzudzu, UV LED   mabotolo otsekereza, ndi okwera galimoto UV LED   oyeretsa mpweya.

Masonono Njira ya UV LED   imagwiritsidwa ntchito pochotsa tizilombo toyambitsa matenda ndi mpweya komanso kuyeretsa photocatalytic m'magalimoto UV LED   oyeretsa mpweya.

Ndi ukadaulo wamakono wa UVC woyengetsa wa LED, womwe ulibe poizoni komanso wopanda mercury, wopanda ma radiation kapena fungo, mulingo wa UV wa makapu ophera tizilombo a UVC LED amatha kufika mpaka 99%.

Pamene ntchito mu a UV LED   msampha wa udzudzu, Ma LED a UV ndi pazipita kuwala linanena bungwe mwina efficiently kukopa udzudzu kudera lalikulu. Amapanganso CO2 kudzera mu photocatalytic reaction yokhala ndi TiO2 yokutidwa mkati mwa denga lapamwamba.
