Chithandizo cha kuwala kwa LED ndi chithandizo chosavulaza chomwe chimagwiritsa ntchito mafunde osiyanasiyana a kuwala kwa infrared kuti chithandize kuchiza mavuto osiyanasiyana a pakhungu monga ziphuphu, mizere yopyapyala, ndi kuchiritsa mabala. Kwenikweni chinapangidwa koyamba kuti chigwiritsidwe ntchito kuchipatala ndi NASA m'zaka za m'ma 90 kuti chithandize kuchiritsa mabala a pakhungu a astronaut - ngakhale kafukufuku pankhaniyi akupitiliza kukula, ndikuthandizira, zabwino zake zambiri.
“Mosakayikira, kuwala kooneka kumatha kukhala ndi zotsatirapo zamphamvu pakhungu, makamaka m'njira zamphamvu kwambiri, monga mu ma laser ndi zida zamphamvu zowunikira (IPL),” akutero Dr. Daniel, dokotala wa khungu wodziwika bwino wokhala ku New York City. LED (yomwe imayimira diode yotulutsa kuwala) ndi “njira yotsika yamphamvu,” momwe kuwalako kumayamwidwa ndi mamolekyu omwe ali pakhungu, zomwe “zimasintha ntchito ya maselo apafupi.”
Mwachidule, chithandizo cha kuwala kwa LED "chimagwiritsa ntchito kuwala kwa infrared kuti chikwaniritse zotsatira zosiyanasiyana pakhungu," akutero Dr. Michele, dokotala wa khungu wovomerezeka ndi board yemwe amakhala ku Philadelphia, PA. Pa chithandizo, "mafunde a kuwala kooneka amalowa pakhungu mosiyanasiyana kuti agwiritse ntchito mphamvu ya zamoyo." Mafunde osiyanasiyana ndi ofunikira, chifukwa ichi ndi "chomwe chimathandiza kuti njira iyi ikhale yogwira mtima, chifukwa imalowa pakhungu mosiyanasiyana ndikulimbikitsa zolinga zosiyanasiyana za maselo kuti zithandize kukonza khungu," akutero Dr. Ellen, dokotala wa khungu wovomerezeka ndi board ku New York City.
Izi zikutanthauza kuti kuwala kwa LED kwenikweni kumasintha ntchito ya maselo a khungu kuti apange zotsatira zosiyanasiyana zabwino, kutengera mtundu wa kuwala komwe kukukambidwa - komwe kuli kochuluka, ndipo palibe chomwe chili ndi khansa (chifukwa mulibe kuwala kwa UV).
