Kuvandudzwa kweUV Leds pasi peDenda

Zvirwere zvine chekuita neutano uye zvinokonzerwa nemvura zvinodhura pasi rose mabhiriyoni emadhora gore negore uye zviuru zvehupenyu gore negore. Imwe nhanho inokosha yekudzivirira kubereka, iyo inogona kuitwa nenzira dzakasiyana-siyana, kusanganisira ultraviolet (UV) chiedza cheradiation. Sezvo maitiro ekuita sterilizing achigona kumisa kutapurirana kwezvirwere zvinotapukira, ichi chinodiwa chave nekukasira nekuda kwedenda repasi rose re coronavirus.

Kuenzaniswa ne semiconductor mwenje masosi, masosi aripo senge mercury bulbs akakura, ane njodzi, uye ane mashoma ekushandisa sarudzo.

Chii Iine UV LEDs ?

UV-LEDs ma LED anogadzira UV maranzi ane wavelengths ye400 nm kana pasi. Iwo akapatsanurwa kuita yakadzika-ultraviolet LEDs (DUV-LEDs), iyo ine emission wavelength inosvika mazana maviri-.3 2 0 nm, uye pedyo-ultraviolet mwenje-emitting diodes (NUV-LEDs), ane emission wavelength inosvika. 3 2 0-400 nm.

MaUV-LED ari kuvimbisa vakwikwidzi kune akati wandei maapplication, kusanganisira kutsiva mwenje weUV, fluorescence mwenje masosi ekuratidzira uye mwenje, yakanaka yekuvhenekesa masosi emamicroscopes uye exposure equipment,
zvitubu zvechiedza chemakemikari excitation 4 inoshandiswa mubiotechnology, mushonga, uye resin kurapa, kuwedzeredza mwenje masosi espectroscopy anoshandiswa mukuzivikanwa kwemanoti emari, machipisi eDNA, uye kutarisa kwezvakatipoteredza, uye hutsanana hwemwenje masosi ekuuraya hutachiona uye sterilization.

Kusikwa kweUv Leds

Kunyangwe mudenda ririkuenderera mberi, kuuraya utachiona mafomite itsika yakakosha yehutano hweveruzhinji mukumisa kutapurirana kwezvirwere zvakawanda zvinotapukira. Hapana mubvunzo kuti pane kufarira kugadzira tekinoroji inobvumira kuuraya hutachiona hwenguva dzose, hwepamusoro-soro, kunyanya munzvimbo dzinoshanyirwa zvakanyanya, zvichipihwa ruzivo rwechangobva kuitika rwekubatana kwepedyo uye kutamba kwemukati mukutapurirana hutachiona.

Zvisinei nekushanda kwavo, makemikari anoshanda mumakemikari echinyakare ekuuraya utachiona mumakiriniki nemarabhoritari anoisa mamiriro ekunze, hutano hweveruzhinji, uye njodzi dzezvivakwa zvinoita kuti kupararira kwavo kuome. Pamusoro pezvo, kushanda kwemakemikari ekuuraya utachiona kunogona kusiyana zvichienderana nemushandisi uye nemafambiro avanoita nemazvo maitiro ekuchenesa anodzokororwa. Seimwe nzira, ultraviolet (UV) mwaranzi yakashandiswa zvakanyanya kumisa tupukanana twakawanda, kusanganisira mavhairasi. Ultraviolet mwenje inogona otomatiki kugadzira inodzokororwa germicidal dose.

Nhanganyaya ye uv led diode inopa chiyero chakafanana chekubvisa tsvina semarambi echinyakare mecury, asi nezvakanakira zvakati wandei, zvinosanganisira kureruka kwekudzoreredza mune akasiyana siyana akajairwa pamusoro pemwenje masosi, nekugonesa kuuraya hutachiona.

Kushanda kweUV yekuchenesa kunoratidzwa nenzira yayo yakatwasuka yekushanda. Nepo vavakidzani mabhesi ethymine (kana uracil mabhesi mune yeRNA) achitambura dimerization, izvo zvinokanganisa chimiro chenyucleotide kutevedzana uye kugadzira "nzira dzakavharika" mukudzokorodza kwegenome, padyo nenyucleotide mabhesi muDNA neRNA inongotora UV mafotoni.

Vatsvakurudzi vakaratidza kushanda kwe antiviral kwe Uv nekumisa mavhairasi maviri: yemwaka yemunhu Coronavirus 229E (hCoV-229E) uye immunodeficiency virus rudzi 1 (HIV-1). Vatsvagiri vanoratidza kudzikiswa kwakanyanya mukudzokororwa kwehutachiona mukati memasekondi mushure mekuratidzwa kweUV-LED nekuenzanisa zviitiko zvakajairwa zvezvakatipoteredza zvekupararira kwehutachiona (semuenzaniso, kutsveta, kukosora, madonhwe eropa) vachishandisa nzira dzekuparadzira madonhwe.

Tsvagiridzo yedu inobatsira kumutumbi weruzivo pakushandisa UV-LED kuchenesa nzvimbo dzine veruzhinji. MaUV-LED anomiririra imwe, inoshanda kwazvo yekudzivirira kubva pathogen kupararira nekuti haina mari uye iri nyore kuisa mumhando yezvigadziriso zvemwenje, kunyanya panguva yechirwere chekufema.

Zvinodikanwa zveUV-LEDs

Nine 275 nm LEDs mu 3 3 array uye makumi maviri ne 380 nm ma LEDs mu 4 5 array anosanganisira maviri seti eUV-LED akapihwa. Chinhambwe pakati pemaLED uye sampu yakafumurwa yaive yakatenderedza masendimita mashanu, uye mwenje weUV wakabuda kubva kune imwe neimwe yakarongwa kubva pa0.4 kusvika 0.6 mW/cm2.

Iyo yakakwirira yemwaranzi nguva yaive masekonzi makumi matatu, uye akasanganiswa arrays akapa dhamu yakazara kune radioactive samples kubva pa8 mJ/cm2 kusvika 20 mJ/cm2. Nzvimbo yese yakavhenekerwa yemudziyo wacho yaive yakatenderedza masendimita gumi ne20 cm, kana 200 cm2, yakakura zvakanyanya kupfuura sampuro yakaiswa irradiated, uye yakagamuchira aquifer dose ye1.6 J kusvika 4 J.

Mhedzisiro Kutsvagiridzo Yekuvandudza kweUV LED Pasi peDenda

Uv   zvakaratidzwa muzvidzidzo izvi kuti zvinoshanda pakumisa mabhakitiriya anodzivirira UV, HIV-1, uye Coronavirus 229E yemunhu. Panyaya yekoronavirus yemunhu, takaona kudzikiswa kwehutachiona kudzokororwa kusvika pa5.8-Log. Sezvo kukuvadzwa kweRNA kuri iyo chaiyo nzira yekudzima neUV irradiation uye sei-229E hutachiona hweRNA, vaongorori vanofanotaura kuderedzwa kwakafanana kwekutapukira mushure mekusangana neUV.

Nekudaro, ivo havana kuongorora zvakananga kana kudzikiswa uku mukudzokororwa kwehCoV-229E kunoenderana nekudzikisira kwakafanana kwekutapukira. Vatsvagiri vanoyambira kuti mhedzisiro yedu inogona kushandiswa zvakananga kuongorora kushanda mukuchenesa mavhairasi asina kuputirwa nekuti anowanzo kusimba kuUV kupfuura mavhairasi akafukidzwa.

Muchidzidzo ichi, tsvakiridzo dzinoratidza kuti magadzirirwo edu ehutachiona akasarudzwa aive mavhairasi akafukidzwa, akasarudzwa kuti aongorore chero mutsauko unogona kuitika mukugamuchira UV nekuda kwehutachiwana genome kureba.

Kusashanda kweB. pumilus spores, ane mukurumbira wekuva nehupamhi hwekusimba kweUV, yakaratidzwa mumiedzo yedu. Vatsvagiri vanoti uhwu hunogona kunge huri humbowo hwekutanga hwekuti mavhairasi asina kuvharwa anogona kuvharwa nemwenje weUV. Yakakurudzirwa kushandisa B. pumilus spores seyekumira-mukati yekuyedza kusashanda kweiyo isina kuputirwa rotavirus yemunhu nemwaranzi yeUV.

Ndekupi Kwaunogona Kutenga Yako UV LED Kubva?

Iine yakakwana yekugadzira inomhanya, inowirirana mhando uye kuvimbika, uye mutengo unokwanisika, Tianhui Electronics   anga achishanda mu Mhinduro UV LED   Kutengesa. UV   L ed vagadziri   huya muUVA, UVB, uye UVC wavelengths. Zvichienderana neakasiyana UV maapplication, akawanda marudzi e uv led diode   anowanikwa, akadai UV LED   zviteya zveumhutu, UV LED   mabhodhoro esterilization, uye akaiswa-mota UV LED   kuchenesa mweya.

Mazuva Ano Mhinduro UV LED   inoshandiswa kumhepo yekubvisa pathogen uye kucheneswa kwefotocatalytic mumotokari UV LED   kuchenesa mweya.

Iine yekucheka-kumucheto UVC LED sterilization tekinoroji, iyo isiri-chepfu uye isina mercury-isina, isina mwaranzi kana kunhuwa, iyo UV sterilization mwero weUVC LED disinfecting makapu thermally inogona kusvika kusvika 99%.

Kana yakashandiswa mu a UV LED   chiteya cheumhutu, UV LEDs nehupamhi hwekubuda kwemaziso hunogona kukwezva umhutu pamusoro penzvimbo yakakura. Ivo zvakare vanogadzira CO2 kuburikidza nephotocatalytic reaction ine yakavharwa TiO2 padivi remukati redenga repamusoro.
