LAMP ON LIGHT-EMITTING DIODES Russian patent published in 2009 - IPC F21S8/00 

FIELD: lighting.

SUBSTANCE: proposed invention relates to lighting technology particularly to optical sources - lamps. On semiconductors radiating light-emitting diodes, generating radiating red, green, yellow, blue, white, near-infrared radiation or mixed colours. Aim of the invention is improving the heat and light technical parameters of the lamp on strong light-emitting diodes with simultaneous simplification of the design and increasing its compactness. Lamp contains one, two or more flat plates round or of a polygonal form, mounted on a constricting element on a distant and parallel among themselves group of light-emitting diodes, installed one by one or more at a thermal contact on individual radiators, made in the form of flat curved under selected angles flat blades from a heat-conducting material, placed with a space between themselves and with a given orientation in space. Blades-radiators are made directly on plates, mechanically fixed to them, and the light-emitting diodes mounted on them have optical axes, perpendicular to the plane of the installation. Plane plates are made from heat-conducting metal or from an electro-insulating material, printed-circuit board with unsoldered on it current-carrying outlets of the light-emitting diodes. Lower plane plate in the form of printed-circuit board with unsoldered on it outlets of the light-emitting diodes is connected with the chamber for the electronic transducer supply mains, which can be connected to a standard socle, and the armature of the lamp with light-emitting diodes enclosed in the optically transparent bulb filled with a heat-conducting gas.

EFFECT: improving the heat and light technical parameters of the lamp on strong light-emitting diodes with simultaneous simplification of the design and increasing its compactness.
