ʻO ke kahua noi a UVLED a me nā pilikia palekana

ʻO ka lōʻihi o ka nalu o nā kukuna ultraviolet ma waena o ke kukui ʻike ʻia a me ka X-ray. ʻO 10 a 400nm kona lōʻihi nalu. Eia naʻe, manaʻo ka nui o nā mea hana photoelectric he ultraviolet ka nalu o 430nm. ʻOiai ʻaʻole ʻike ʻia ka nui o nā kukuna ultraviolet e nā kānaka, ua kapa ʻia lākou no ka spectrum generator o kekahi Violet. Ua holomua ka UV LED i nā makahiki i hala iho nei. ʻAʻole kēia wale nō ka hopena o ka holomua ʻenehana o ka mīkini paʻa UV, akā ma muli o ka piʻi ʻana o ka noi no nā kukui UV e hana ana i nā wahi pōʻino. ʻO ka hāʻawi ʻana o UV LED i kēia manawa ma ka mākeke optoelectronics e loaʻa ana ka nui o ka nalu o 265 a 420nm. Nui nā ʻano o ka hoʻopili ʻana, e like me ka perforation, ka hoʻokomo ʻana i ka ʻili a me COB. Loaʻa i ka mea hoʻoheheʻe UV LED nā ʻano hana like ʻole. Eia naʻe, kūʻokoʻa kēlā me kēia mīkini hana i ka nalu a me ka mana hoʻopuka. ʻO ka maʻamau, hiki ke hoʻokaʻawale ʻia ke kukui UV i hoʻohana ʻia ma LED i ʻekolu mau māla. Ua wehewehe ʻia lākou he UV-A (ʻo ka hawewe ultraviolet lōʻihi), ʻo UV-B (ke ultraviolet hawewe haʻahaʻa) a me ka U VC (ke ultraviolet hawewe pōkole). Ua hana ʻia kahi mea UV mai ka makahiki 1990. Hoʻohana pinepine ʻia kēia mau LED i ka hoʻāʻo ʻana a i ʻole ka hōʻoia ʻana (kālā, laikini kaʻa a faila, etc.). He haʻahaʻa loa nā koi puka mana o kēia mau noi. ʻO ka laulā nalu maoli ma loko o 390 a 420N m. ʻAʻole kūpono nā huahana haʻahaʻa haʻahaʻa no nā noi. No ka mea hiki ke hoʻohana ʻia kēia mau LED 'ola lōʻihi a me ka hana maʻalahi i ka mākeke e like me nā kumu kukui like ʻole a me nā huahana UV loa. Ua ulu nui ka māhele UVA LED i nā makahiki i hala iho nei. ʻO ka hapa nui o kēia hawewe lōʻihi (e pili ana i 350 390nm) ʻo ia ka hana ʻana i nā mea kūʻai aku a me nā mea ʻenehana, e like me ka hoʻopili, nā uhi, a me nā inika. Ma muli o ka hoʻomaikaʻi ʻana o ka pono, ka emi ʻana o ke kumukūʻai, a me ka miniaturization, ʻoi aku ka maikaʻi o nā kukui LED ma mua o ka ʻenehana solidification kuʻuna, e like me ka mercury a i ʻole nā ​​kukui fluorescent. No laila, hoʻolaha mau ke kaulahao hoʻolako i ka hoʻohana ʻana i ka ʻenehana LED, e hana ana i ke ʻano o ka paʻa ʻana o nā LED i ʻoi aku ka ʻike. ʻOiai ʻoi aku ka kiʻekiʻe o ke kumukūʻai o kēia hawewe nalu ma mua o ka UV A, ʻo ka holomua wikiwiki o ka ʻenehana hana hana a me ka hoʻonui mau ʻana o ka hua e hoʻemi mālie i ke kumukūʻai. ʻO ka haʻahaʻa UV A a me ke kiʻekiʻe o ka lōʻihi o ka hawewe UV B (e pili ana i 300-350nm) nā wahi i kūʻai ʻia. Ua kūpono kēia mau mea hana nui no nā noi he nui, me ka mālama ʻana i ka ultraviolet, biomedical, DNA analysis, a me nā ʻano ʻano ʻano like ʻole. Aia kahi overlap koʻikoʻi i kēia 3 UV spectral range. No laila, i ke koho ʻana, ʻaʻole pono ʻoe e noʻonoʻo wale i ke ʻano o ka noi kūpono loa, akā pono nō hoʻi e noʻonoʻo i ka hopena o ke kumu kūʻai. No ka mea, ʻo nā haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka nui o nā kumukūʻai LED. ʻO UV B a me UV C ka lōʻihi o ka hawewe (e pili ana i 250-300nm) kahi nui i ka pae hoʻomaka. Eia naʻe, ikaika loa ka hoihoi a me ke koi no ka hoʻopili ʻana i ia mau huahana i ka ea a me ka ʻōnaehana hoʻomaʻemaʻe wai. I kēia manawa, hiki i nā hui liʻiliʻi ke hana i nā LED UV i loko o kēia laulā nalu, a hiki i kekahi mau hui ke hana i nā huahana me ke ola kūpono, hilinaʻi a me nā hiʻohiʻona hana. No laila, kiʻekiʻe loa ke kumukūʻai o ka mea UVC/B, a paʻakikī ke hoʻohana i kekahi mau noi. ʻO kahi nīnau maʻamau e pili ana i ka UV LED: E lawe mai lākou i nā pōʻino palekana huna? E like me ka mea i ʻōlelo ʻia ma luna, he nui nā pae kukui UV. ʻO ke kumu kukui UV i hoʻohana pinepine ʻia he ʻeleʻele ʻeleʻele. Ua hoʻohana ʻia kēia huahana no nā makahiki. Hoʻohana ʻia ia e hana i nā hopena māmā a i ʻole fluorescent no nā pepa, a me ka hōʻoia ʻana o ka pena a me ke kālā. ʻO ke kukui i hana ʻia e kēia mau ʻōpuʻu kukui ma ke ʻano he UV A, kokoke loa i nā nalu māmā ʻike a me ka ikehu haʻahaʻa. ʻOiai ua hōʻike ʻia ka ʻike kiʻekiʻe e pili ana i ka maʻi maʻi ʻili a me nā pilikia ʻē aʻe, e like me ka wikiwiki o ka ʻili, ʻo ka spectrum UVA ka palekana loa i nā kukui UV ʻekolu. Hoʻohana nui ʻia ka UV C a me ka hapa nui o nā kukui UV B no ka sterilization a me ka disinfection. ʻAʻole ʻino wale kēia mau nalu o ka māmā i nā microorganism. Pono e paʻa mau kēia mau kukui LED, a ʻaʻole pono lākou e nānā pono i nā maka ʻōlohelohe, ʻoiai inā he liʻiliʻi loa ia. ʻO ka ʻike ʻia ʻana i ka mālamalama o kēia mau hawewe hiki ke kumu i ka maʻi maʻi ʻili a me ka nalo ʻana a i ʻole ka nalo mau ʻana.
