The device relates to light-emitting diode lamps. The technical result consists in a device that provides a colder state of the light-emitting diodes and, correspondingly, the illuminance of said light-emitting diodes increases (increased brightness) and the service life is extended. The claimed technical result is achieved by virtue of the fact that the light-emitting diode lamp comprises a bulb, a base for insertion into a lampholder, light-emitting diodes connected to base contacts via a microcircuit, and a heat sink for transferring heat from the light-emitting diodes, wherein the light-emitting diodes are mounted on a heat pipe which is formed with a bottom and a hollow support with heat-transfer agent, while elements of the heat sink, which is connected to the bottom of the heat pipe, are arranged around and beneath the lamp bulb, wherein a heat-transfer agent is arranged inside the cavity of the heat pipe, said heat-transfer agent functioning in the boiling phase, while the electrical power supply contacts are passed to the light-emitting diodes via current-conducting tracks or wires passing over the surface of the heat pipe, characterized in that the light-emitting diodes are arranged on the bottom, which is connected to the heat pipe vie a heat-conducting material, while a blower fan which is connected to a piezoelectric element capable of producing high-frequency mechanical oscillations of the fan is arranged within the heat sink. |
