Hoʻomohala ʻana o nā Led UV ma lalo o ka maʻi maʻi

ʻO nā maʻi e pili ana i ke olakino a me nā maʻi i lawe ʻia i ka wai ke kumu kūʻai ʻana o ka honua i nā piliona kālā i kēlā me kēia makahiki a me nā kaukani ola i kēlā me kēia makahiki. ʻO kahi hana pale koʻikoʻi ka sterilization, hiki ke hoʻokō ʻia me ka hoʻohana ʻana i nā ʻano like ʻole, me ka ultraviolet (UV) light irradiation. No ka mea hiki i nā kaʻina hana sterilizing kūpono ke hoʻōki i ka hoʻouna ʻana i nā maʻi maʻi, ua ʻoi aku ka wikiwiki o kēia koi ma muli o ka maʻi maʻi coronavirus honua.

Hoʻohālikelike ʻia i nā kumu kukui semiconductor, ʻoi aku ka nui o nā kumu e like me nā ʻōpala mercury, ʻino, a he liʻiliʻi nā koho noi.

Lau i He mau LED UV ?

ʻO nā UV-LED nā LED e hoʻopuka i nā kukuna UV me nā lōʻihi hawewe o 400 nm a i ʻole. Ua hoʻokaʻawale ʻia lākou i loko o nā LED ultraviolet hohonu (DUV-LED), nona ka lōʻihi o ka hawewe emission ma kahi o 200-3 2 0 nm, a kokoke i ka ultraviolet light-emitting diodes (NUV-LEDs), nona ka lōʻihi hawewe 3 2 0-400 nm.

Ke hoʻohiki nei nā UV-LED i nā moho no kekahi mau noi, me ka hoʻololi ʻana i nā kukui UV, nā kumu kukui fluorescence no nā hōʻike a me nā kukui, nā kumu kukui maikaʻi no nā microscopes a me nā mea hoʻolaha,
nā kumu māmā no ka hoʻoulu kemika 4 hoʻohana ʻia i ka biotechnology, lāʻau lapaʻau, a me ka resin curing, excitation light source no spectroscopy i hoʻohana ʻia i ka ʻike kālā memo, DNA chips, a me ka nānā ʻana i ke kaiapuni, a me nā kumu kukui maʻemaʻe no ka disinfection a me ka sterilization.

Hana ʻia nā Uv Leds

ʻOiai i kahi maʻi maʻi e hoʻomau nei, ʻo ka disinfecting fomites kahi hana olakino olakino koʻikoʻi i ka hoʻōki ʻana i ka lawe ʻana i nā maʻi maʻi he nui. ʻAʻole kānalua ka makemake i ka hana ʻana i ka ʻenehana e hiki ai ke hoʻomaʻamaʻa maʻamau, kiʻekiʻe-throughput disinfection, ʻoi aku hoʻi i nā wahi lehulehu i kipa nui ʻia, hāʻawi ʻia i ka ʻike hou o ka pili pili kokoke a me ka pāʻani ʻana i loko o ka hoʻoili ʻana i ka maʻi virus.

ʻOiai ka maikaʻi o lākou, ʻo nā kemika ikaika i nā disinfectants kemika kuʻuna i nā hoʻonohonoho lapaʻau a me nā keʻena hoʻokolohua e hoʻopilikia i ke aniau, ke olakino lehulehu, a me nā ʻoihana e paʻakikī ai kā lākou hoʻolaha ākea. Hoʻohui ʻia, hiki ke ʻokoʻa ka hopena o nā disinfectants kemika ma muli o ka mea hoʻohana a me ke akahele o ka hahai ʻana i nā kaʻina hana hoʻomaʻemaʻe. ʻO kahi ʻokoʻa, ua hoʻohana nui ʻia ka radiation ultraviolet (UV) e hoʻopau i nā microorganisms he nui, me nā maʻi maʻi. Hiki ke hoʻomaʻamaʻa ʻia ke kukui Ultraviolet e hana i kahi maʻi germicidal hou.

ʻO ka hoʻokomo ʻana o EaohaKa eho Hāʻawi i ka pae like o ka decontamination e like me nā kukui mercury kuʻuna, akā me nā pono he nui, me ka maʻalahi o ka hoʻihoʻi hou ʻana i nā kumu kukui maʻamau maʻamau, me ka hiki ke hoʻomaʻemaʻe.

Hōʻike ʻia ka maikaʻi o UV no ka hoʻomaʻemaʻe ʻana e kāna ʻano hana maʻalahi. ʻOiai ʻo nā kumu thymine kokoke (a i ʻole nā ​​kumu uracil i ka hihia o RNA) e ʻeha i ka dimerization, ka mea e hoʻopau i ke ʻano o nā kaʻina nucleotide a hana i "nā ala ala" i ka replication genome, nā kumu nucleotide e pili ana i ka DNA a me ka RNA e hoʻopili kūʻokoʻa i nā kiʻi UV.

Ua hōʻike ka poʻe noiʻi i ka hopena antiviral o a Ae Ka Huohao ma ka hoʻopau ʻana i ʻelua mau maʻi maʻi: ʻo ka coronavirus 229E kanaka (hCoV-229E) a me ka maʻi immunodeficiency type 1 (HIV-1). Hōʻike nā mea noiʻi i nā hōʻemi nui o ka hoʻopiʻi viral i loko o kekona ma hope o ka hoʻolaha ʻana o UV-LED ma o ka hoʻohālikelike ʻana i nā hanana kūlohelohe maʻamau o ka hoʻopuehu ʻana i nā maʻi (e laʻa, ʻoki, ʻū, kulu koko) me ka hoʻohana ʻana i nā ala hoʻopuehu droplet.

Hāʻawi kā mākou noiʻi i ke kino o ka ʻike e pili ana i ka hoʻohana ʻana i nā UV-LED e hoʻomaʻemaʻe i nā wahi ākea kiʻekiʻe. Hōʻike nā UV-LED i kahi papa ʻoi aku ka maikaʻi o ka pale ʻana i ka laha pathogen no ka mea he maʻalahi lākou a maʻalahi hoʻi e hoʻokomo i loko o kahi ʻano o nā kukui kukui e kū nei, ʻoi aku hoʻi i ka wā o ka maʻi maʻi hanu.

Pono no nā UV-LED

ʻEiwa mau LED 275 nm i loko o kahi 3 3 array a me iwakālua 380 nm LED i loko o kahi 4 5 i loaʻa nā pūʻulu ʻelua o nā UV-LED i hoʻolako ʻia. ʻO ka mamao ma waena o nā LED a me ka laʻana i hōʻike ʻia ma kahi o 5 knm, a ʻo ka puka kukui UV mai kēlā me kēia laina mai 0.4 a 0.6 mW/cm2.

ʻO 30 kekona ka lōʻihi o ka radiation, a ua hāʻawi nā hui i hui pū ʻia i ka nui o ka nui i nā laʻana radioactive mai ka 8 mJ/cm2 a i ka 20 mJ/cm2. Ma kahi o 10 knm a 20 knm ka nui o ka mea i ho'omālamalama'ia, a 'o 200 knm2 paha, 'oi aku ka nui ma mua o ka hāpana irradiated, a ua loa'a iā ia ka nui aquifer dose o 1.6 J a 4 J.

Nā hopena i ka noiʻi ʻana no ka hoʻomohala ʻana o nā LED UV ma lalo o ka maʻi maʻi

Ae Ka Huohao   Ua hōʻike ʻia i loko o kēia mau haʻawina e hana maikaʻi i ka hoʻopau ʻana i ka maʻi bacteria pale UV, HIV-1, a me ke kanaka Coronavirus 229E. I ka hihia o ka coronavirus kanaka, ʻike mākou i ka hōʻemi ʻana i ka hoʻopiʻi viral a hiki i 5.8-Log. No ka mea ʻo ka pōʻino RNA ke ʻano kikoʻī o ka holoi ʻana e ka UV irradiation a pehea ka-229E he maʻi RNA, wānana ka poʻe noiʻi i ka emi ʻana o ka maʻi maʻi ma hope o ka ʻike ʻana iā UV.

Akā naʻe, ʻaʻole lākou i loiloi pololei inā pili kēia hōʻemi i ka hoʻopiʻi hCoV-229E me kahi hōʻemi like o ka infectivity. Hoʻomaopopo ka poʻe noiʻi e hiki ke hoʻopili pololei ʻia kā mākou hopena e loiloi i ka maikaʻi o ka hoʻomaʻemaʻe ʻana i nā maʻi i hoʻopaʻa ʻole ʻia no ka mea ʻoi aku ka maʻalahi o ka UV ma mua o nā maʻi i hoʻopaʻa ʻia.

Ma kēia haʻawina, hōʻike ʻia nā noiʻi ʻo kā mākou hoʻolālā virus i koho ʻia he mau maʻi i hoʻopili ʻia, i koho ʻia e loiloi i nā ʻokoʻa like ʻole o ka loaʻa ʻana o UV ma muli o ka lōʻihi genome viral.

ʻO ka hana ʻole ʻana o B. ʻO pumilus spores, ka mea i kaulana no ka loaʻa ʻana o ke kiʻekiʻe kiʻekiʻe o UV resilience, i hōʻike ʻia i kā mākou mau hoʻāʻo. Wahi a nā mea noiʻi ʻo ia paha ka hōʻike mua e hiki ke hoʻopau ʻia nā maʻi ʻaʻole i hoʻopaʻa ʻia e ke kukui UV. Ua manaʻo ʻia e hoʻohana i ka B. pumilus spores ma ke ʻano he kūpaʻa no ka hoʻāʻo ʻana i ka hana ʻole o ka rotavirus kanaka i hoʻopaʻa ʻole ʻia e ka radiation UV.

Ma hea ʻoe e kūʻai ai i kāu LED UV mai?

Me ka holo hana piha, ka maikaʻi mau a me ka hilinaʻi, a me nā kumukūʻai kūpono, Tianhui Electronics   ua hana ma ka Donmake aʻu aoi   Kele. UV   L ed mea hana   hele mai ma UVA, UVB, a me UVC nā nalu nalu. Ma muli o nā noi UV like ʻole, nui nā ʻano o EaohaKa eho   loaʻa, e like me UV LED   pahele namu, UV LED   nā ʻōmole sterilization, a me nā kaʻa i kau ʻia UV LED   nā mea hoʻomaʻemaʻe ea.

Pake Donmake aʻu aoi   Hoʻohana ʻia no ka hoʻopau ʻana i ka pathogen airborne a me ka hoʻomaʻemaʻe photocatalytic i ka automotive UV LED   nā mea hoʻomaʻemaʻe ea.

Me ka ʻenehana sterilization UVC LED ʻokiʻoki, ʻaʻohe mea ʻawaʻawa a me ka mercury-free, me ka ʻole o ka radiation a i ʻole ka ʻala, hiki ke piʻi i ka nui o ka UV sterilization no nā kīʻaha disinfecting UVC LED i ka thermally hiki ke kiʻekiʻe a hiki i 99%.

Ke hoʻohana ʻia i kahi UV LED   pahele namu, Nā LED UV me ka puka aniani kiʻekiʻe e hiki ke hoʻomake maikaʻi i nā makika ma kahi ʻāpana nui. Hoʻopuka pū lākou i ka CO2 ma o ka hopena photocatalytic me TiO2 i uhi ʻia ma ka ʻaoʻao o loko o ka hale luna.
