LED USING LUMINESCENT SAPPHIRE AS THE LOWER-RETURN TRANSVERSER Russian patent published in 2019 - IPC H01L33/02 H01L33/50 

FIELD: lighting devices.

SUBSTANCE: light-emitting device according to the invention comprises semiconductor layers of a light-emitting diode (LED) comprising an N-type layer, an active layer, emitting primary light, and P-type layer; and luminescent sapphire connected to semiconductor layers, wherein LED semiconductor layers and luminescent sapphire are part of LED chip, wherein luminescent sapphire contains oxygen vacancies, which lead to formation of F-type centers having given optical absorption and emission luminescence bands; luminescent sapphire, absorbing part of primary light and converting with decreasing primary light for emission of secondary light through centers of F-type so that radiation from LED crystal included at least combination of primary light and secondary light. Method of manufacturing the light-emitting device is also proposed.

EFFECT: invention provides cost reduction, higher conversion efficiency and higher reliability.
