LED LAMP Russian patent published in 2015 - IPC F21V29/00 H01L33/00 F21Y101/02 

FIELD: electricity.

SUBSTANCE: LED lamp comprises a bulb of transparent material, a replaceable radiating element and a fixture made as an electric holder. The fixture comprises a body and at least one pair of spring contacts designed to be connected to the power supply unit. The replaceable radiating element has the central cooling radiator, which is covered by a flexible printed board from three sides. The printed board has tracks; at that at least one light-emitting diode is installed at the top side. Two lateral sides of the printed board touch spring contacts forming a current-conducting connection between the spring contacts and tracks of the printed board. The lamp comprises at least two lateral cooling radiators, which are connected to the bulb at the one side and to the body at the other side. Two lateral sides of the central cooling radiator and lateral sides of the printed board covering them are crimped between two side cooling radiators thus forming thermal contact of the printed board with the central and side cooling radiators.

EFFECT: improved heat removal, which allows using powerful light-emitting diodes.
