Background technology
At present, along with the cry of protection environment, energy savings is more and more higher, the development and utilization of new forms of energy is applied to the practice from the laboratory theory more and more and goes.And people have been difficult to the power supply illumination under outdoor and outlying situation.And more original put-puts are still too heavy, and simple and easy the carrying that be difficult for going out.
Thermo-electric generation is a kind of novel generation mode, and its operation principle is at two semiconductor of different nature two ends a temperature difference to be set, and utilizes the Sai Beier effect that heat energy directly is converted to electric energy, so just produced DC voltage on semiconductor.Semiconductor generator so that semi-conductor thermo-electric generation module is made can generate electricity as long as there is the temperature difference to exist.The semiconductor thermoelectric generating has characteristics such as noiselessness, life-span length, stable performance, can start rapidly in subzero 40 degrees centigrade cold environment.Semiconductor temperature difference generator is mainly used in fields such as oil field, field, military affairs at present, and its another market-oriented field is TRT is used for the utilization of solar energy, underground heat, industrial wasted energy etc., makes heat energy be converted into electric energy.In addition, semiconductor electricity generation module volume is little, and is in light weight, is easy to carry, and can be widely used in small household appliances manufacturing, instrument and meter, toy and tourist industry.If the two sides thermal gradient energy reaches 60 degree Celsius, then generating voltage can reach 3.5V, and electric current can reach 3-5A.
The development of semiconductor temperature difference assembly generation technology and hot pipe technique provides feasibility for solving the portable power supplies problem.The present invention promptly utilizes a kind of portable desk lamp of semiconductor temperature difference art designs.
Summary of the invention
A kind of desk lamp of semiconductor temperature difference assembly generating comprises lampshade, bulb, and lamp bracket, lamp socket is characterized in that lampshade is made by radiating fin; The lamp bracket bottom is separated by by the semiconductor temperature difference assembly with lamp socket communication place, and the hot junction of semiconductor temperature difference assembly is following, and cold junction upwards; Lamp bracket inside is cavity, and cavity center is equipped with heat pipe, and the heat pipe bottom links to each other with the cold junction of semiconductor temperature difference assembly, and the lamp bracket wall is made by heat-barrier material, is embedded with lead in the lamppost wall; Inboard wall of lamp holder is a cavity, the built-in combustion source, and the lamp socket wall is made by memorial alloy, and memorial alloy links to each other with the hot junction of semiconductor temperature difference assembly, on the lamp socket wall air vent is arranged.
Preferably, the lamp socket wall has side door to put into Combustion Source.
Preferably, Combustion Source is candle or alcolhol burner.
The beneficial effects of the utility model are, when Combustion Source works in the hot junction of semiconductor temperature difference assembly, provide power supply by the semiconductor temperature difference assembly to bulb, and the bulb in the lampshade is lighted.The characteristic that inboard wall of lamp holder utilizes memorial alloy to expand with heat and contract with cold, the flexible automatically hot junction distance of adjusting Combustion Source and temperature difference module is controlled and is prevented that hot-side temperature is too high.Lamp bracket is overheated for preventing outer wall, uses heat-barrier material.Lampshade provides the cooperation of large tracts of land radiating fin to dispel the heat.

The specific embodiment
Be illustrated in figure 1 as the utility model embodiment, this desk lamp is by lampshade 1, bulb 4, and lamp bracket 2, lamp socket 3 is formed, and lampshade 1 is made by radiating fin; Lamp bracket 2 bottoms and lamp socket 3 communications place are separated by by semiconductor temperature difference assembly 6, and the hot junction of semiconductor temperature difference assembly 6 is following, and cold junction upwards; Lamp bracket 2 inside are cavity, and cavity center is equipped with heat pipe 7, and heat pipe 7 bottoms link to each other with the cold junction of semiconductor temperature difference assembly 6, and the wall of lamp bracket 2 is made by heat-barrier material, is embedded with lead 8 in the lamp bracket wall; Lamp socket 3 inwalls are cavity, built-in combustion source 5 (being a candle) herein, lamp socket 3 walls are made by memorial alloy, and memorial alloy links to each other with the hot junction of semiconductor temperature difference assembly 6, on lamp socket 3 walls air vent 10 is arranged, and lamp socket 3 walls have a side door 9 to insert Combustion Source 5.
Duty of the present utility model is as follows: when lighted candle 5, candle 5 works in the hot junction of semiconductor temperature difference assembly 6, provides power supply by semiconductor temperature difference assembly 6 to bulb 4, and the bulb 4 in the lampshade 1 is lighted.The fin of heat pipe 7 and lampshade 1 is the cold junction heat radiation of semiconductor temperature difference assembly 6, to keep the cold and hot end temperature difference of semiconductor temperature difference assembly 6.
Below in conjunction with Fig. 2 and Fig. 3 a working cycles of the present utility model is described once:
As shown in Figure 2, when lighted candle after a period of time, temperature raises, because memorial alloy has the characteristic of significantly expanding with heat and contract with cold, stretch gradually, the flame of Combustion Source will be gradually away from the semiconductor temperature difference assembly, until separating fully, this moment, the semiconductor temperature difference assembly still continued to provide power supply to bulb because the temperature difference also exists, and the hot junction of semiconductor temperature difference assembly begins to dispel the heat gradually.
As shown in Figure 3, when semiconductor temperature difference assembly hot-side heat dissipation proceeds to certain phase, the hot junction and the cold-end temperature difference of semiconductor temperature difference assembly fade away, the memorial alloy that links to each other with the hot junction is because temperature reduces shrinkage gradually, the flame of Combustion Source is gradually near semiconductor temperature difference assembly hot junction, until contact fully, begin to act on semiconductor temperature difference assembly hot junction again, provide thermal source with generating.
Above process is a working cycles.
Being preferred embodiment of the present utility model only below, is not to be used to limit protection scope of the present invention.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
