LIGHT DIODE LAMP Russian patent published in 2013 - IPC H01L33/00 

FIELD: electricity.

SUBSTANCE: light diode lamp comprises an envelope, a base for insertion into a cartridge, light diodes connected via a microchip to contacts of the base and a radiator for heat transfer from light diodes. Besides, light diodes are installed on a thermal tube, which is made with the base and a hollow coolant leg, and around the lamp envelope and underneath there are elements of the radiator connected with the base of the thermal tube. Inside the cavity of the thermal tube there is a coolant arranged, which operates in the boiling phase, and contacts of power supply to light diodes are pulled via current-conducting path or wires stretching along the surface of the thermal tube. Light diodes are arranged on the base, which is connected with the thermal tube via a heat conducting material, and inside the radiator there is a blow fan, which is connected to a piezoelement arranged as capable of creating high-frequency mechanical oscillations of the fan.

EFFECT: provision of a colder condition of light diodes and accordingly increase of their luminosity and service life.
