LED LAMP WITH RADIATOR Russian patent published in 2014 - IPC F21S8/00 F21Y101/02 

FIELD: electricity.

SUBSTANCE: LED lamp comprises a frame with radiator (FR) made as an elongated body with inner cavity, at its lateral side there are longitudinal-oriented fins (F) with slots, a board with light-emitting diodes, which is installed in FR, and voltage converter (VC) placed in the FR plane. Technical result is attained due to performance of the FR shaped as a cup (C) with open butt end and at external surface of the cup walls there are fins (F). Slot in the A are made as grooves (G) oriented along the lamp longitudinal axis, which are open from the side of the open butt end of C. Each G passes through the whole thickens of the F and divide it into outside and inner parts. The FR is equipped with KP an end plate-type flange to which the upper sections of the F outside parts join, the flange is installed so that it forms in the cross-sectional plane a circular gap between the flange and C walls, and the gap value corresponds to G. The C walls are embedded in regard to the upper surface of the end flange. The VC is placed in the C cavity in the area corresponding to the G layout area. The LED board has the central via opening, it is installed at the end flange with formation of a gap between its lower surface and upper surface of C walls.

EFFECT: improving efficiency of heat removal.
