LED Yakavakirwa Sterilization uye Disinfection Zvigadzirwa Zvinongogona Kubviswa, Indica

Denda reCovid-19 rasimudza ruzivo rweveruzhinji nezve UV disinfection, iyo inoratidzwawo mukuwedzera kwenhamba yezvigadzirwa zve LED pamusika. Ultraviolet mwenje inogona kushandiswa kuuraya hutachiona hwemhepo, mvura uye nzvimbo dzezvinhu zvakasiyana. International ultraviolet Association (iuva) inoti inogona kubatsira kuderedza njodzi yekutapurira hutachiona hwecovid-19. Chiedza che Ultraviolet chakakamurwa kuita mitsara yakawanda (Mufananidzo 1). UV-A kana mwenje nhema inotangira pa315 kusvika 400 nm uye inoshandiswa mumashandisirwo akadai sekuyedza kugadzikana, kurapa, phototherapy, zvinodzinga zvipembenene nemibhedha yekutsvuka. Kugara kwenguva refu kuUV-A kunogona kukonzera kutsvuka kweganda uye kuchembera nguva isati yakwana.Mufananidzo 1 ultraviolet chiedza chakakamurwa kuita siyana dzakawanda.

UV-B muwavelength renji ye280 ~ 315 nm ine njodzi. Nokuti kuratidzwa kwenguva refu kuUV-B kune chokuita nekuitika kwekenza yeganda, kukwegura kweganda uye cataract, kushandiswa kwekutengeserana kunosanganisira kuchengetedza uye phototherapy mumishonga.The wavelength muhuwandu hwe200 ~ 280nm ndeye UV-C. Iri bhendi reUV harina chekuita negomarara reganda nekuti mafotoni haapinde zvakadzika muganda, asi maererano neuva tsvagiridzo, kuratidzwa kune UV-C kunogona kukonzera kusagadzikana kweganda sekutsva kwakanyanya uye kukuvadza retina yemaziso. UV-C mafotoni anogona zvakare kudyidzana neRNA uye DNA mamorekuru mumamicroorganisms kuti anyatso aparadza. Mercury vapor marambi anogona kuburitsa UV-C ave achishandiswa kuuraya hutachiona kwemakumi emakore. Nekudaro, semamwe marudzi ekuvhenekesa, ivo vakachinjira kune zvigadzirwa vachishandisa LED mwenje masosi.

Nyanzvi dzehutano dzinotenda kuti nzira huru yekutapurirana kweCovid-19 ndeyekusangana nemadonhwe ekufema mumhepo kana pamusoro pezvinhu. Parizvino iripo LED based sterilization uye disinfection zvigadzirwa zvinonyanya kushandiswa kuuraya hutachiona hwepasi. Nekuwedzera kwemisika yemidziyo iyi, masisitimu epamusoro ekuuraya hutachiona hwemhepo ndiwo anogona kuunzwa. Zvigadzirwa zviripo zvine zvakanakira kuve wakakodzera kune mamwe marudzi ekuvhenekesa kwe LED: diki diki, nyore kusanganisa nemamwe madhivhisi seavepo sensors, uye yakaderera simba rekushandisa zvinodiwa. Nekudaro, zvigadzirwa izvi zvinowanzo kudhura zvakanyanya, uye pachava nezvimwe zvirambidzo pane huwandu hwenzvimbo dzepamusoro dzinogona kugadziriswa munguva chaiyo.

Kutarisa kwekutanga kwekuchinja kune maLED kwaive kuderedzwa kukuru kwehupenyu hwe LED kana ichienzaniswa nemarambi aripo emercury vapor. Nekudaro, kushushikana uku kunobva pakuongorora kuenderera mberi kwekushanda mumashandisirwo echinyakare senge akavharwa ekuchenesa masisitimu, uye haafunge kuti zvigadzirwa zvebhakitiriya zvinogona (uye dzimwe nguva zvinofanirwa) kushandiswa nguva nenguva. Kufanana nema LED ese, UV-C ma LED anogona kutenderera kusvika risingapere pasina kukanganisa kubuda kwechiedza; Uye zvakare, iyo mercury vapor rambi inoda maminetsi akati wandei enguva yekupisa kuti isvike pakubuda kwechiedza, uye zvigadzirwa zve LED zvinogona kusvika padanho rakazara rekubuda nekukasira. Pamusoro pezvo, kusiyana nemarambi emercury vapor, led based products inogona kungopa wavelength inodiwa kuti ive nemhedzisiro yakanaka pasina kutambisa simba nenzira yekusaita wavelengths.

Kazhinji kutaura, rimwe dambudziko rekugadzira zvigadziriso zvekuvhenekesa zvigadzirwa ndeyekuongororwa kwekuchengetedzwa kwechigadzirwa uye kuita zvinodiwa. Sekureva kwaCarl Bloomfield, director wepasirese webhizinesi zvivakwa mubhizinesi remagetsi reEntertek, kuongororwa kwechigadzirwa kwavo kwakanangana nekupenya paramita, cerrilization statement verification, kutevedzera kuchengetedza, uye inoshanda EMC. Masangano ekusimudzira zviyero atanga kuyedza zviyero, asi zviyero hazvisati zvavepo, saka EUROLAB inovimba neindasitiri yayo uye hunyanzvi hwehunyanzvi kugadzira mapuroteni ekuyera ezvigadzirwa uye zvavanoda mashandisirwo. Kuteerera kuchengetedza kunogona kunyanya kuomarara nekuti zvinoenderana nechigadzirwa uye mashandisiro acho, kusanganisira moto, kuvhunduka kwemagetsi, njodzi yemakina, njodzi dzemaziso, kubuda kweUV uye kuburitsa ozone.

Pamusoro pezvigadzirwa zveUV disinfection, kune ichangoburwa chigadzirwa chinyorwa chinonzi "visible light disinfection (VLD)". Zvigadzirwa izvi zvinoshandisa indigo (blue purple) wavelengths inoburitswa ne LEDs, izvo zvakachengeteka kuti muviri wemunhu uratidzwe kwenguva yakareba, kuitira kuti urambe uchibvisa mabhakitiriya anonzwa kune aya wavelengths. Zvigadzirwa zveVLD zvinowanzoiswa munzvimbo sechikamu che iyo yekuvhenekesa kwechigarire mwenje, uye dzimwe nguva inoshandiswa pamwe chete nechena mwenje masosi ekuvhenekesa. Zvakakosha kucherechedza kuti VLD disinfection haishande kune ese mabhakitiriya uye haina kunyatsoshanda kune mavhairasi.
