ILLUMINATION DEVICE Russian patent published in 2008 - IPC F21S9/02 

FIELD: lighting.

SUBSTANCE: lighting device has a thermo-electric generator, on the first junction of which there is container with volatile liquid, a bowl and a lamp, fitted in space, bordered by the bowl, and connected to the thermo-electric generator. The container is a cup, made from an aluminium rectangular parallelepiped, in which on the opposite side of fixing the thermo-electric generator there is an indention in form of a segment of a sphere. On the second junction of the thermo-electric generator there is a resistive heater, which is in form of a resistive film, deposited on the ceramic lining of the thermo-electric generator. The base of the container together with the thermo-electric generator and the resistive heater are covered in a transparent dielectric compound, from which the bowl is moulded. The colour of the bowl is regulated during manufacturing using different colouring additives, added to the compound. The lamp is a set of light emitting diodes, connected to the thermo-electric generator parallel to the resistive heater.

EFFECT: design of a lighting device with use of a semiconductor thermo-electric generator for producing electrical energy, on which at least parameters of the surrounding medium are affected, increased efficiency of using the thermo-electric generator.
