Pehea e hana ai ke kukui UV

UVC

Ma mua o ka pane ʻana i kēia nīnau e ʻike i ke ʻano ʻo UV Lighting.

ʻO ka mea mua, e nānā kākou i ka manaʻo o UV. ʻO UV, a i ʻole ultraviolet, a i ʻole ultraviolet, kahi nalu electromagnetic me kahi lōʻihi lōʻihi ma waena o 10nm a me 400nm. Hiki ke hoʻokaʻawale ʻia ka UV o nā nalu ʻokoʻa i UVA, UVB a me UVC.

UVA: lōʻihi ka nalu, ma waena o 320-400nm, hiki ke komo i loko o nā ao a me ke aniani i loko o ka lumi a me ke kaʻa, a hiki ke komo i loko o nā dermis o ka ʻili, e hoʻoulu ana i ka lā. Hiki ke mahele ʻia ʻo UVA i uva-2 (320-340nm) a me UVA-1 (340-400nm).

UVB: aia ka nalu i waena, ma waena o 280-320nm. E hoʻopili ʻia e ka ozone layer, e hoʻoulu ana i ka lā a me ka ʻulaʻula o ka ʻili, ka pehu ʻana, ka wela a me ka ʻeha. I nā hihia koʻikoʻi, e kū mai ka pehu a me ka ʻili.

UVC: aia ka nalu ma waena o 100-280nm, akā no ka mea ʻo ka lōʻihi ma lalo o 200nm kahi vakumena ultraviolet, hiki ke komo ʻia e ka ea, no laila ʻo ka nalu o UVC hiki keʻaʻa i ka lewa ma waena o 200-280nm, ʻoi aku ka pōkole a ʻoi aku ka weliweli o ka ʻo ka nalu ka lōʻihi, akā no ka mea hiki ke ālai ʻia e ka ozone layer, e kau wale kahi liʻiliʻi i ka ʻili o ka pōpō honua.

Pehea e hana ai ʻo UVC i ka sterilization
Hiki iā UV ke luku i ka hanana molekiola o DNA (Bacilli) a i ʻole RNA (Virus) o nā microorganisms, a make i ka bacteria a i ʻole hiki ʻole ke hana hou, i mea e loaʻa ai ka pahuhopu o ka sterilization.

No laila he pane ka ʻAe.
Hiki i ke kukui UVC ke pepehi iā Covid-19

Ke kukui UVC Mercury a me ke kukui UVC LED
ʻO ka mōʻaukala, ʻo ke kukui mercury ke koho wale no ka hoʻokau ʻana o UV. Eia nō naʻe, ua komo ka mana o Minamata Convention on mercury no Kina mai ʻAukake 16, 2017. Koi ʻia ka Convention e pāpā ʻia ka hana ʻana, ka lawe ʻana mai a me ka lawe ʻana aku i ka mercury i loaʻa nā huahana i hōʻike ʻia i loko o ka Convention mai Ianuali 1, 2021, a ʻo ka mercury lamp kekahi e helu ʻia ma aneʻi. No laila, ʻaʻole nui ka manawa i koe no ke kukui mercury, a ʻo UVC LED wale nō kahi koho pono.
