POLYMER-COATED LIGHT-EMITTING DIODE MODULE Russian patent published in 2010 - IPC H01L33/56 

FIELD: electricity.

SUBSTANCE: light-emitting diode module has a bearing element made in form of a solid body having an upper and a lower base and a lateral surface, and at least one semiconductor light-emitting element on the upper base of the bearing element. On top of the semiconductor light-emitting element on the upper base of the bearing element there is a coating made from an optically transparent silicon compound. The coating is dome-shaped and the base of the coating is inscribed in the area of the upper base of the bearing element. The angle between the lateral surface of the bearing element and its upper base is not greater than 120°. The coating is formed by depositing a drop of the said compound, which has viscosity of 2000-20000 cP, on top of the semiconductor light-emitting element and subsequent hardening of the compound.

EFFECT: increased reliability of the structure and improved optical properties of the light-emitting diode module.
