340-350nm UVB LEDs - Nthano vs. Zowona

Pakhala pali zokambirana zambiri pakati pa asayansi ndi anthu onse za cheza cha ultraviolet B (UVB), makamaka m'dera la 340-350 nm. Pakhala pali nkhawa zokhudzana ndi chitetezo ndi zotsatira za thanzi zomwe ma ultraviolet B light-emitting diode (LEDs) amatha kugwiritsidwa ntchito ngakhale kuti amagwiritsidwa ntchito kwambiri m'madera monga chithandizo chamankhwala, kuyeretsa madzi, ndi chitukuko chaulimi. Kufotokozera chisokonezo ndi kuwunikira kuopsa ndi ubwino wogwiritsa ntchito 340 nm LED - 350nm LED (UVB), nkhaniyi ipereka chidule chatsatanetsatane chothandizidwa ndi deta yasayansi ndikuyesera kutsutsa zina mwazolakwika zokhudzana ndi chitetezo chawo.

Chidziwitso chofala cha zotsatira za cheza cha ultraviolet (UV) pa minofu yamoyo ndiye gwero lalikulu la mkangano wozungulira. Ma LED a UVB . Mavuto ambiri a thanzi, monga khansa yapakhungu, ukalamba, ndi kuwonongeka kwa maso, angayambe chifukwa chokhala ndi kuwala kwa ultraviolet kwa nthawi yaitali. Komabe, anthu ambiri amakhulupirira kuti kuwala kwa dzuwa ndi koopsa kumakayikira chifukwa chogwiritsa ntchito ma radiation  ultraviolet-B kuwala-emitting diodes  m'makonzedwe oyendetsedwa bwino komanso pazolinga zomwe mukufuna. Kupereka maziko olimba kuti muwunike mwatsatanetsatane mbiri yachitetezo cha UV LED 340 nm, UV LED 350nm , gawoli liyerekeza kutulutsa kwawo komanso kulimba kwawo ndi kuwala kwa dzuwa ndi magwero achilengedwe a UV.

Nthano 1: 340nm-350nm Ma radiation a UVB Ndiwowopsa

Kusamvetsetsana kofala ndikuti kuopsa kwaumoyo wopangidwa ndi magwero osiyanasiyana ndi kutalika kwa kuwala kwa UVB ndizofanana. Nthano iyi ikupitilizabe kunyalanyaza mfundo yakuti mafunde osiyanasiyana a UV ali ndi zotsatira zosiyana kwambiri za chilengedwe. Mwachitsanzo, a 340 nm UVB LED- 350nm UVB LED imakwaniritsa chosowa chapadera chifukwa itha kukhala yothandiza pa ntchito zina popanda kubweretsa zoopsa zomwe zimafanana ndi magulu ena a UVB.

Kupanga vitamini D pakhungu ndi njira yofunikira kwambiri yopangira chitetezo chamthupi komanso thanzi la mafupa, ndipo kafukufuku akuwonetsa kuti kuwala kwa UVB mu 340nm led-350nm led range ingagwiritsidwe ntchito pa izi. Ikagwiritsidwa ntchito moyenera, mawonekedwe a 340-350 nm a radiation ya ultraviolet B amapereka njira yosangalatsa pakati pa kuwonongeka kwa DNA ndi chiwopsezo cha khansa, mosiyana ndi mafunde amfupi a UVB. Mvetsetsani kuti kuwopsa komwe kumalumikizidwa ndi ma UVB LED kumadalira kwambiri kulimba, nthawi, komanso nthawi yowonekera.

Ma protocol okhwima amakakamiza kugwiritsa ntchito  ultraviolet B kuwala-emitting diodes m'malo azachipatala ndi achire pochiza chikanga, vitiligo, ndi psoriasis. Izi zimagwiritsa ntchito zinthu zabwino za UV LED 340nm , UV LED 350nm pochepetsa zinthu zoyipa pogwiritsa ntchito zida zodzitchinjiriza komanso kuwonekera kwanthawi yake. Kuchita bwino kwa njira zochiritsirazi kumakayikira chikhulupiriro chakuti UVB ndi yovulaza kwenikweni ndipo imagogomezera kufunika kwa kusiyanitsa pakati pa kutalika kwa mafunde ndi kagwiritsidwe ntchito kake.

Kuwongolera kwaukadaulo wa LED kwapangitsa kuti zitheke kuwongolera ndendende kutalika kwa kuwala komwe kumatulutsidwa, kuchepetsa kukhudzidwa mwangozi ndi ma UV oopsa kwambiri; komabe, malingaliro olakwika akupitilirabe kuti ma radiation onse a UVB ndi owononga chimodzimodzi. Malamulo aposachedwa azaumoyo amakhazikitsa malire ovomerezeka amphamvu ya radiation komanso kutalika kwa mawonekedwe, omwe ali ochepa mu UVB l yamakono. ma diode opepuka . Ma LED awa amamangidwa ndi chitetezo m'malingaliro.

Zambiri zasayansi ndi upangiri wa akatswiri, osati ma phobias ofala okhudza ma radiation a UV, ayenera kudaliridwa kuti athetse chinyengo ichi. Kuzindikira ubwino ndi kuopsa kwa ma UVB LEDs, kulimbikitsa kugwiritsidwa ntchito kwa maphunziro, ndi kukhazikitsa njira zodzitetezera kuti muchepetse zotsatira zosafunikira zonse ndizofunikira chifukwa cha zovuta zake.

Nthano 2:  340-350nm LED  Kuyambitsa Khansa Yapakhungu

Lingaliro kuti 340 nm LED -350nm LED kukhudzidwa kumayambitsa kuwonongeka kwa khungu nthawi yomweyo ndipo khansa yapakhungu ndichinyengo chofala. Ngakhale kuti ndi zoona pamafunde enaake komanso mawonekedwe owonekera, kuopa kowopsa kwa zotsatira zowononga za UV kumayimira molakwika kuwonekera kwa UVB LED.

Mukasamalidwa bwino, 340 nm UVB LED-350nm UVB LED ikhoza kugwiritsidwa ntchito pazachipatala zomwe zili ndi chiopsezo chochepa chifukwa cha kuchepetsedwa kwa mawonekedwe a UV. Kuwonetseredwa koyang'aniridwa ndi ma UVB LED pamtunduwu kumapangitsa kaphatikizidwe ka vitamini D ndi kuwonongeka kochepa kwa DNA kuposa mafunde amfupi a UV, omwe amalumikizidwa kwambiri ndi khansa yapakhungu. Kutalika kwa mawonekedwe oyendetsedwa ndi mphamvu, komanso njira zodzitetezera monga mafakitale kapena chitetezo cha maso ndi khungu, zimachepetsa chiopsezo.

Kafukufuku wochulukirapo azachipatala awonetsa kuti kuwala kwa UVB pamafunde ndi milingo yeniyeni kumatha kuchiza matenda a khungu kuphatikiza psoriasis, popanda kukulitsa chiwopsezo cha khansa yapakhungu. Zotsatirazi zikusonyeza zimenezo  UVB ndi ma diode opepuka  ndi zotetezeka komanso zothandiza moyang'aniridwa ndi akatswiri. Kumbukirani kuti chitetezo chimadalira malamulo oletsa kuwonetseredwa komanso kuchulukira kumagulu omwe samawononga ma cell.

Mtundu wa khungu, chibadwa, ndi kuchulukitsidwa kwa UV m'kupita kwa nthawi ndi zinthu zina zomwe zimakhudza momwe thupi limachitira ndi kuwala kwa UV. Pamalo olamulidwa, kuopsa kwa kuwonongeka kwa khungu ndi khansa yochokera ku UVB LED kumakhala kochepa kwambiri kusiyana ndi kutenthedwa ndi dzuwa kosalamulirika, komwe kumasinthasintha kwambiri. Imaphatikizapo kuchuluka kwa ma radiation a UV.

Nthano 3: 340-350nm Kuwonetsedwa kwa LED kwa UVB Sikotetezeka kwa Maso

Kuopsa kwa ma LED a UVB ku thanzi lamaso ndi nkhawa ina yofala. Anthu ena amaopa kuti ngakhale kuyang'ana pang'ono kungawononge maso kwambiri. Ngakhale photokeratitis ndi ng'ala ndi vuto lenileni la maso chifukwa cha cheza cha ultraviolet, kuopsa kobwera ndi 340nm UV LED -350 nm UV LED ndi nthawi zambiri amakokomeza.

Kuchuluka ndi kutalika kwa mawonekedwe a UVB LED kungakhudze kwambiri chiwopsezo cha kuvulala kwamaso. Kuwala kwa Dzuwa ndi UVC, zomwe zili ndi kutalika kwafupipafupi, ndizowopsa m'maso kuposa UV LED 340nm-UV LED 350nm osiyanasiyana. Kuti muchepetse kwambiri chiopsezo chowonekera m'maso mwangozi, zovala zodzitchinjiriza ndizochita chizolowezi m'malo mwa akatswiri ndi achire omwe amagwiritsa ntchito nthawi zonse.  UVB ndi ma diode opepuka .

Kuphatikiza apo, magetsi amakono a UVB LED ali ndi zodzitetezera zomwe zimachepetsa kuchuluka kwa nthawi ndi mphamvu zomwe ogwiritsa ntchito amakumana nazo kuti zikhale zotetezeka m'maso. Zidazi nthawi zambiri zimakhala ndi zosefera ndi zotchingira kuti muchepetse ngozi ndikupewa kuwonetseredwa mwangozi mukamagwira ntchito.

Pezani yankho Lanu la LED!

Tianhui Electronic wakhala patsogolo pa UVB maphukusi a LED, ndikupereka mndandanda wathunthu wopanga wamtundu wodalirika komanso mitengo yotsika mtengo.

Mayiko opitilira 50 akhala makasitomala athu pazaka 20 zapitazi. Timalonjeza mtengo m'masiku amodzi kapena atatu, chitsanzo m'masiku atatu kapena asanu ndi awiri, ndi kutumiza ndi kutumiza katundu wazinthu zazikulu m'masiku makumi awiri mpaka makumi atatu!
