1. He aha ka UV?

ʻO ka mea mua, e nānā kākou i ka manaʻo o UV. ʻO UV, ʻo ia hoʻi ka ultraviolet, ʻo ia hoʻi ka ultraviolet, he hawewe electromagnetic me ka lōʻihi hawewe ma waena o 10 nm a me 400 nm. Hiki ke hoʻokaʻawale ʻia ʻo UV ma nā ʻāpana like ʻole i UVA, UVB a me UVC.

UVA: me ka nalu lōʻihi mai 320-400nm, hiki iā ia ke komo i nā ao a me ke aniani i loko o ka lumi a me ke kaʻa, komo i loko o nā dermis o ka ʻili a hoʻoulu i ka tanning. Hiki ke hoʻokaʻawale ʻia ʻo UVA i uva-2 (320-340nm) a me UVA-1 (340-400nm).

UVB: aia ka nalu nalu ma waena, a ʻo ka nalu ma waena o 280-320nm. E hoʻopili ʻia e ka papa ozone, e hoʻoulu ai i ka lā, ʻulaʻula ka ʻili, ka pehu, ka wela a me ka ʻeha, a me ka ʻōpala a i ʻole ka ʻili ʻana i nā hihia koʻikoʻi.

UVC: aia ka hawewe ma waena o 100-280nm, akā ʻo ka nalu ma lalo o 200nm he ultraviolet vacuum, no laila hiki ke hoʻopili ʻia e ka lewa. No laila, ʻo ka lōʻihi o ka nalu e hiki ai i ka UVC ke hele i ka lewa ma waena o 200-280nm. ʻOi aku ka pōkole o kona nalu nalu, ʻoi aku ka pōʻino. Eia naʻe, hiki ke ālai ʻia e ka papa ozone, a he wahi liʻiliʻi wale nō e hiki i ka ʻili o ka honua.

2. Kumu o UV sterilization?

Hiki i ka UV ke hoʻopau i ka DNA (deoxyribonucleic acid) a i ʻole RNA (ribonucleic acid) molecular structure o nā microorganisms, i make ai ka bacteria a ʻaʻole hiki ke hana hou, i mea e hoʻokō ai i ke kumu o ka sterilization.

3. UV sterilization band?

Wahi a ka International ultraviolet Association, "ʻo ka ultraviolet spectrum (ka 'sterilization' region) he mea nui loa no ka wai a me ka ea disinfection ʻo ia ka laulā i hoʻopili ʻia e DNA (RNA i kekahi mau maʻi). ʻO kēia hui sterilization ma kahi o 200-300 nm ". Ua ʻike ʻia ka lōʻihi o ka hawewe sterilization i ʻoi aku ma mua o 280nm, a i kēia manawa ua manaʻo ʻia e hoʻonui i 300nm. Eia naʻe, hiki ke loli kēia me ka noiʻi hou aku. Ua hōʻoia ka poʻe ʻepekema ʻo ke kukui ultraviolet me nā lōʻihi nalu ma waena o 280nm a me 300nm hiki ke hoʻohana ʻia no ka sterilization.

4. He aha ka nalu kūpono no ka sterilization?

Aia ke kuhi hewa ʻana ʻo 254 nm ka nalu maikaʻi loa no ka sterilization, no ka mea, ʻo 253.7 nm ka lōʻihi haʻahaʻa haʻahaʻa haʻahaʻa mercury kukui (hoʻoholo wale ʻia e ka physics o ke kukui). ʻO ke kumu, e like me ka mea i hōʻike ʻia ma luna nei, he hopena bactericidal kekahi ʻano o nā lōʻihi nalu. Eia nō naʻe, manaʻo nui ʻia ʻo ka nalu o 265nm ka mea maikaʻi loa, no ka mea, ʻo kēia hawewe ka piko o ka puʻupuʻu absorption DNA. No laila, ʻo UVC ka hui kūpono loa no ka sterilization.

5. No ke aha i koho ai ka mōʻaukala iā UVCLED?

ʻO ka mōʻaukala, ʻo ke kukui mercury wale nō ke koho no ka sterilization UV. Eia naʻe, ka miniaturization oLED UVCʻO nā ʻāpana e lawe mai i ka noʻonoʻo ʻana i ka hiʻohiʻona noi, ʻaʻole hiki ke ʻike ʻia e nā kukui mercury kahiko. Eia kekahi, he nui nā pōmaikaʻi o UVC alakaʻi, e like me ka hoʻomaka wikiwiki ʻana, ʻoi aku ka ʻae ʻia o nā manawa hoʻololi, loaʻa ka mana o ka pākaukau a pēlā aku.

6. UVC LED noiʻi hiʻona?

ʻO ka sterilization o ka ʻili: nā mea hoʻopili ākea kiʻekiʻe e like me nā mea lapaʻau, nā lako makuahine a me nā pēpē, ka halepaku naʻauao, ka pahu hau, ke keʻena papa ʻaina, ka pahu mālama hou, ka ʻōpala naʻauao, ke kīʻaha thermos, ka lima escalator a me ke pihi mīkini kūʻai tiketi;

ʻO ka hoʻomaʻemaʻe wai: pahu wai o ka dispenser wai, humidifier a me ka mea hana hau;

Kahe wai sterilization: kahe wai sterilization module, pololei inu wai dispenser;

Ea sterilization: ea hoʻomaʻemaʻe, air conditioner.

7. Pehea e koho ai i nā LED UVC?

Hiki ke koho ʻia mai nā ʻāpana e like me ka mana optical, ka lōʻihi o ka nalu, ke ola lawelawe, ke kihi puka a pēlā aku.

ʻO ka mana Optical: ʻo ka UVC LED optical power i loaʻa i ka mākeke o kēia manawa mai 2MW, 10 MW a 100 MW. Loaʻa i nā noi like ʻole nā ​​koi mana. Ma ka ʻōlelo maʻamau, hiki ke hoʻohālikelike ʻia ka mana optical ma ka hoʻohui ʻana i ka mamao irradiation, koi ikaika a i ʻole koi static. ʻOi aku ka nui o ka mamao o ka irradiation, ʻoi aku ka ikaika o ke koi, a ʻoi aku ka nui o ka mana optical e pono ai.

Ka lōʻihi nalu: e like me ka mea i ʻōlelo ʻia ma luna nei, ʻo 265nm ka nalu maikaʻi loa no ka sterilization, akā e noʻonoʻo ana he liʻiliʻi ka ʻokoʻa o ka nui o ka hawewe kiʻekiʻe ma waena o nā mea hana, ʻoiaʻiʻo, ʻo ka mana optical ka papa kuhikuhi nui loa e ana i ka pono sterilization.

Ke ola lawelawe: e noʻonoʻo i ka koi no ke ola lawelawe e like me ka manawa lawelawe o nā noi kikoʻī, a loaʻa i ka UVC kūpono i alakaʻi ʻia, ʻo ia ka mea maikaʻi loa.

ʻO ke kihi puka māmā: ʻo ke kihi puka māmā o nā pahu kukui i hoʻopili ʻia me ka lens plane ma waena o 120-140 °, a ʻo ke kihi puka māmā i hoʻopili ʻia me ka lens spherical hiki ke hoʻololi ʻia ma waena o 60-140 °. ʻO ka ʻoiaʻiʻo, ʻaʻole pili i ka nui o ke kihi puka o UVC LED i koho ʻia, hiki ke hoʻolālā ʻia nā LED e uhi piha i ka wahi sterilization makemake. I ka hiʻohiʻona insensitive i ka sterilization laulā, hiki i kahi kihi kukui liʻiliʻi ke hoʻonui i ke kukui, no laila ua pōkole ka manawa sterilization.
