The device relates to light-emitting diode lamps. The technical result consists in a compact light emitter which does not produce a light loss and which illuminates at angles of 360x270x270 degrees, in which the radiator is designed so as to be capable of significantly increasing the area of the radiator without any growth in the dimensions of the lamp. The claimed technical result is achieved in that the light-emitting diode lamp, which comprises a bulb, a cap for insertion into a lampholder, light-emitting diodes which are coupled to the contacts of the cap via a microcircuit, and a radiator for transmitting heat from the light-emitting diodes, is characterized in that the light-emitting diodes are mounted on a heat pipe which is formed with a base and a hollow heat-transfer leg, and elements of the radiator which is connected to the base of the heat pipe are arranged around the bulb of the lamp and beneath this, wherein a heat-transfer medium which functions at the boiling phase is arranged inside the cavity of the heat pipe, and contacts of the electrical power supply to the light-emitting diodes are passed via conductor tracks or a wire running over the surface of the heat pipe. |
