Ma nyali a LED ndi njira yodalirika yowunikira kwamakono m'malo opezeka anthu ambiri komanso m'nyumba. Tsopano ndiotchuka chifukwa chogwiritsa ntchito mphamvu zawo zamagetsi. Mu 1927, LED idapangidwa ndi O.V. Losev, komabe, nyali za LED zidalowa mumsika wa ogula m'ma 1960. Okonza amayesetsa kuti atenge ma LED amitundu yosiyanasiyana, ndipo m'ma 1990, nyali zoyera zidapangidwa, zomwe zitha kugwiritsidwa ntchito m'moyo watsiku ndi tsiku. Kodi ndibwino kugwiritsa ntchito mababu a LED kunyumba kwanu? Kuti muyankhe funso ili, muyenera kudziwa momwe kuyatsa kwa LED kumakhudzira thanzi la munthu.
Kuipa kwa ma LED ku ziwalo za masomphenya
Pofuna kutsimikizira mtundu wa nyali za LED, maphunziro angapo adachitidwa ndi asayansi aku Spain. Zotsatira zawo zidawonetsa kuti zimatulutsa mphamvu ya cheza chofewa, chomwe chimakhala ndi violet, makamaka buluu, kuwala. Zimakhudza ziwalo za masomphenya, zomwe zimatha kuwononga diso la diso. Kutentha kwa buluu kumatha kuvulaza mitundu iyi:
- photothermal - kumabweretsa kutentha;
- photomechanical - zotsatira za kuwomba kwamphamvu kwa kuwunika;
- photochemical - kusintha pamlingo wa macromolecular.
Pamene maselo a retinal pigment epithelium asokonezeka, matenda osiyanasiyana amawoneka, kuphatikiza izi zimabweretsa kutayika kwathunthu kwamaso. Monga asayansi atsimikizira, kutulutsa kwa kuwala kwa buluu m'maselowa kumabweretsa imfa. Kuunikira koyera ndi kobiriwira kumakhalanso kowopsa, koma pang'ono pang'ono, ndipo kufiyira sikovulaza. Ngakhale izi, kuyatsa kwa buluu kumalimbikitsa zokolola zambiri komanso kumawongolera chidwi.
Akatswiri samalimbikitsa kugwiritsa ntchito kuyatsa kwa LED nthawi yamadzulo komanso usiku, makamaka asanagone, chifukwa zimatha kuthandizira ku matenda otsatirawa:
- matenda a khansa;
- matenda a shuga;
- matenda amtima.
Kuphatikiza apo, katulutsidwe ka melatonin kamaponderezedwa mthupi.
Kuipa kwa LED ku chilengedwe
Kuphatikiza pa thupi la munthu, kuyatsa kwa LED kumakhudza chilengedwe. Ma LED ena amakhala ndi tinthu tating'onoting'ono ta arsenic, lead, ndi zinthu zina. Ndizowopsa kupumira utsi womwe umapangidwa nyali ya LED ikuswa. Chotsani ndi magolovesi otetezera ndi mask.
Ngakhale zovuta zake ndizowonekera, nyali za LED zimagwiritsidwa ntchito ngati magetsi. Sakuwononga chilengedwe poyerekeza ndi nyali zokhala ndi mercury. Pochepetsa zovuta paumoyo, simuyenera kugwiritsa ntchito ma LED nthawi zonse, yesetsani kupewa mawonekedwe amtambo, komanso pewani kugwiritsa ntchito kuyatsa kotere musanagone.
