LIGHT DIODE LIGHTING DEVICE Russian patent published in 2012 - IPC F21V3/00 

FIELD: electricity.

SUBSTANCE: invention relates to lighting equipment. The device comprises a thin-walled body made of a heat conducting material with conical and cylindrical parts and a partition between them arranged inside the body, ribbing outside the body, at the same time the body is arranged in the form of a solid part without slots, a mineral glass fixed in the conical part of the body, a circuit board attached to the partition in the cavity of the conical part of the body oppositely to the glass, arranged from a heat conducting material and having light guides, current-conducting paths for supply of light diodes and fastening holes, a supply and control unit arranged on the partition in the cavity of the cylindrical part of the body, having a printed circuit board with current-conducting paths for electronic components, and also fastening screws. The circuit board with light guides is pressed to the partition via a heat-transfer pad. Connection of the circuit board with light guides with the partition and the supply and control unit with the partition is made by fastening screws arranged in insulating bushings and stretched via the specified circuit board, partition and supply and control body. At least two of the above screws are arranged in the form of conductors.

EFFECT: reduced dimensions, higher durability and operational characteristics.
