LIGHT-EMITTING DEVICE AND METHOD TO MANUFACTURE LIGHT-EMITTING DEVICE Russian patent published in 2014 - IPC H01L33/48 

Abstract RU 2525325 C2

FIELD: electricity.

SUBSTANCE: group of inventions may be used in indicators, lighting fixtures, displays, sources of light to illuminate liquid-crystal displays. A light-emitting device according to the invention comprises a base and electric conductive components, placed a base, a light-emitting element, having a semiconductor layer and a transparent substrate; a reflecting component, not covering at least a part of side surfaces and an upper surface of the transparent substrate, and covering side surfaces of the semiconductor layer; and a light-transmission component, covering a part of the transparent substrate, not covered with a reflecting element, at the same time the light-emitting element is fixed on electroconductive components, besides, on the surface of these electroconductive components at least a part of the surface of electroconductive components, on which the light-emitting element is not fixed, is coated with an insulating filler with thickness of 5 mcm or more, which is a reflecting component, and the light-transmission component covers the light-emitting element.

EFFECT: invention provides for the possibility of efficient light discharge outside and high reliability of a device, and also to reduce wear of components that make up the device.
