LED LAMP Russian patent published in 2015 - IPC F21S8/00 F21V29/00 H01L33/00 F21Y101/02 

FIELD: electricity.

SUBSTANCE: invention relates to lighting engineering and can be used for manufacture of the light sources used as a part of lighting equipment for the general and local external and internal lighting. The LED lamp contains the convex lens, the board with light-emitting diodes installed from the end face side of the hollow radiator and the connector for connection to the power supply circuit placed in the radiator cavity. The technical result is achieved due to that the radiator cavity contains the thin-walled cylinder made of heat-conducting electric insulating material. Between the board and the named cylinder the metal orifice is installed with a possibility of heat exchange, meanwhile on the lower base of the thin-walled cylinder the connector for connecting to the power supply circuit is made.

EFFECT: decrease of axial dimensions of the lamp and improvement of conditions of heat exchange between the board of light-emitting diodes and environment.
