Dhawaan, koox cilmi baaris ah oo ka socota Jaamacadda Exeter ee UK waxay ogaadeen in inta badan Yurub, nooc cusub oo wasakhowga iftiinka ah ayaa si isa soo taraysa u soo shaac baxay iyada oo isticmaalka sii kordhayaLED ee nalka dibadda.Waraaqdooda lagu daabacay joornaalka Horumarka Sayniska, kooxdu waxay ku qeexday cilmi-baaris ay ku sameeyeen sawirro laga soo qaaday Saldhigga Caalamiga ah ee Hawada Sare.

Daraasado hore ayaa muujiyay in iftiinka macmalka ah ee deegaanka dabiiciga ah uu saameyn xun ku yeelan karo duurjoogta iyo aadanaha.Tusaale ahaan, cilmi-baadhistu waxay muujisay in xayawaanka iyo bani-aadamkuba ay la kulmaan khalkhal ku yimaadda hab-nololeedyada hurdada, iyadoo xayawaanno badan ay ku wareeraan iftiinka habeenkii, taas oo keenta dhibaatooyin isdaba-joog ah oo badbaado ah.

Daraasadan cusub, masuuliyiin ka socda dalal badan ayaa u ololeynaya isticmaalkaNalalka LED-kawaddooyinka iyo meelaha baabuurta la dhigto, halkii ay ka ahaan lahayd nalalka soodhiyamka ee caadiga ah.Si loo helo faham wanaagsan oo ku saabsan saameynta isbeddelkan, cilmi-baarayaashu waxay heleen sawirro ay qaadeen cirbixiyeennada ku sugan Saldhigga Hawada Caalamiga ah laga bilaabo 2012 ilaa 2013 iyo 2014 illaa 2020. Sawirradan ayaa bixiya hirarka iftiinka iftiinka ee ka wanaagsan sawirada dayax-gacmeedka.

Sawirro, cilmi-baarayaashu waxay arki karaan gobollada Yurub ee u beddelayIftiinka daadka LEDiyo ilaa xad weyn, nalka LED waa la beddelay.Waxay ogaadeen in wadamo ay ka mid yihiin UK, Italy, iyo Ireland ay ka dhaceen isbedelo la taaban karo, halka wadamada kale sida Austria, Germany, iyo Belgium aysan ku dhawaad ​​wax isbedel ah ka dhicin.Mawjadaha dhaadheer ee kala duwan ee iftiinka ay soo saaraan LEDs marka loo eego nalalka sodium, kororka iftiinka buluuga ah ayaa si cad loo arki karaa meelaha loo beddelay iftiinka LED.

Cilmi-baadhayaashu waxay tilmaameen in ay ogaadeen in iftiinka buluuga ah uu faragelin karo soo saarista melatonin ee bini'aadamka iyo xayawaanka kale, taas oo khalkhalaysa habka hurdada.Sidaa darteed, kororka iftiinka buluuga ah ee meelaha nalalka LED-ka ayaa laga yaabaa inay saameyn xun ku yeeshaan deegaanka iyo dadka ku nool kana shaqeeya meelahaas.Waxay soo jeedinayaan in mas'uuliyiintu ay si taxadar leh u darsaan saameynta iftiinka LED-ka ka hor intaanay horumarin mashaariicda cusub.
