The invention relates to the making, in particular to the lighting units.

In inaccessible remote areas, where the production of electric power is difficult, there is an actual issue of the coverage of domestic premises. This issue is solved through the use of various types of combustible materials (for example, in the form of candles, torches, kerosene lamps, etc), as well as electric lighting, running on different types of batteries of electric energy [1]. The disadvantage of these methods is their low efficiency, short duration, and the use of combustible materials, in addition, the negative impact on humans and the environment.

Known thermoelectric generator of electrical energy [2], which could be used to power the lighting device. Thermoelectric power generator is a power supply unit consisting of a source of thermal energy provided in thermal contact with the first spaa battery. Due to the temperature difference between the junctions of thermoelectric battery on the battery there is a potential difference. When connecting to the leads of thermoelectric battery load through it flows the electric current. The load is supplied with electric power. As sources of thermal energy in a thermoelectric generator are applied nuclear reactors, heat sources with radioactive isotopes that are used in the chemical reaction of combustion or thermal energy radiated by the Sun.

The lack of a thermoelectric generator is the obligatory presence of a source of thermal energy.

The aim of the invention is to develop a lighting device using a semiconductor thermoelectric generator for generating electrical energy without an external source of thermal energy.

The design of the lighting device shown in the drawing.

The lighting device includes a thermoelectric battery 1, the first junction which is the capacity of the 2 with the evaporating liquid 3 and the second junction - metal heat sink 4, which is a flat plate with a dome in the form of a truncated cone. The incandescent lamp 5 is placed is th battery 1. The lighting device is mounted on a stand 7.

Lighting device operates as follows.

Poured into the container 2 of the liquid 3 in the process of evaporation lowers the temperature of the first junction thermopile 1. The resulting temperature difference between the junctions of thermopile 1 causes the appearance of a potential difference between its conclusions. Through serially connected to thermoelectric battery 1 through the electric wires 6 incandescent lamp 5 passes electric current, which causes it to glow. The metal heat sink 4 is used to raise the temperature of the second battery junction thermocouples 1 through emitted by incandescent warmth.

SUBSTANCE: solar radiation and vortex wind flow developed inside hollow conical polygonal support. Solar radiation is converted into electric power by stationary conical optically active dome and spinning conical solar battery. Besides, electric power is generated by vortex wind flow developed inside hollow conical polygonal support (PS) to act aerodynamic-shape blades of two three-blade windmills (WDM). Said three-blade WDMs are rigidly fitted on single common shaft inside said PS to run in two parallel planes. Distance between planes of rotation should be not smaller the diameter of said blades. Blades of said WDM located in first parallel plane are shifted through 60 degrees relative to blades of WDM in second parallel plane. All blades feature aerodynamic profile. Aforesaid blades are secured in aluminium rings provided with magnets arranged on outer surfaces of said rings. Magnets poles alternate while coil windings are arranged opposite said poles inside cylindrical section of hollow PS. The number of magnets must not comply with that of coil windings. Vortex airflow inside hollow conical part of PS is developed owing to screw shape of the support faces and temperature difference at inlet of PS conical (confuser) part and outlet (diffuser) part of said support. Air inlet openings are arranged at the base of said PS. Inlet lateral walls ensure the initial swirling of incoming airflow inside said PS. Airflow gets out from said support via rectangular openings located at fop section of said diffuser. Electric power is generated when magnetic force lines cross the winding turns at rotation of WDM blades along with aluminium rings and magnets relative to winding turns under effects of vortex airflow. Electric power generated by tandem photo electronic modules is accumulated in storage batteries. Electronic control unit switches on and off the LED lamps in response to instruction from luminance sensor.

EFFECT: self-contained long-term operation.

SUBSTANCE: proposed thermoelectric battery has alternating p and n semiconductor branches connected in series to set up electric circuit by means of switching plates. Branches are electrically interconnected by bringing in contact p branch, switching plate, and n branch, where p branch contacts one of surfaces of switching plate through its end surface and n branch contacts its other surface. Each branch contacts two switching plates through its opposing end surfaces. Surface area of switching plates is slightly larger than cross-sectional area of p and n branches so that their ends protrude beyond surface of structure formed by thermoelectric battery branches. Ends of odd-numbered switching plates protrude beyond one surface of structure and those of even-numbered switching plates, beyond other surface. Ends of switching plates contact electrically isolated pads made in the form of metal or alloy films covering ceramic plates. Space confined between ceramic plates and surface of structure formed by thermoelectric battery branches is filled with heat insulation.
