Kayan aiki
Gidan gwaje-gwaje yana da diffractometer X-ray DRON-8 daga kamfanin Burevestnik na Rasha (a sama akan KDPV). Wannan shine ɗayan manyan kayan aikin tantance kayan.
Yana taimakawa siffata ingancin sakamakon lu'ulu'u da sifofi ta hanyar auna bakan X-ray diffraction. Don maganin thermal na siriri-fim Semiconductor Tsarin da ake haɓaka, muna amfani da wannan shigarwa na gida.
Muna amfani da tsarin sikelin matukin jirgi na zamani don keɓancewa, gyarawa da warware LEDs. Bari mu yi magana game da na farko (hoton da ke ƙasa a gefen hagu).
Wannan madaidaicin mai rarrabawa ne . Tsari ne mai sarrafa kansa don rarraba ruwa mai ɗorewa. Irin wannan na'ura yana da mahimmanci don aiwatar da kayan phosphor daidai zuwa guntu na LED don cimma launi mai haske da ake so.
