PURPOSE:To obtain a thermoelectric generator having a small size and weight and which can be used also as a light source by forming an upper surface of a thermoelectric generating block in which a thermoelectric generating module is interposed between a heat receiving metal plate and a heat radiating metal plate, placing a lamp in a vessel enclosed with a metal plate and glass between the upper surface and a bottom, and providing a heat radiating fin on the outer surface of the plate. CONSTITUTION:A vessel for filling a lamp 4 is formed by using a base for placing the lamp 4 as a bottom 5, a heat radiating metal plate of a thermoelectric generating block of a structure in which a thermoelectric generating module 2 is interposed between a heat receiving metal plate 3 and the heat radiating metal plate 1 as an upper surface, and surrounding between the upper surface and the bottom with the metal plate and a glass or transparent plastic plate 6. In this case, the metal plate and the plate 1 of the upper surface are sufficiently brought into close contact so as to easily transfer heat, and also connected to the base of the bottom 5 to be integrated. Further, a heat radiating fin 7 is provided on the outer surface of the metal plate. Upper vent holes 9 are provided at the top and lower bent holes 9 are provided at the bottom.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention uses the heat of the flame of a lamp using kerosene or other fuel to generate electricity by thermoelectric generation, and utilizes the light of the flame. The idea is to utilize the generated electricity.

(Prior art) Devices that use heat from combustion to generate electricity through thermoelectric power generation are mainly for industrial use and are large and heavy.
Many have an output of several tens of watts or more. There are consumer products available, but they are heavy and large, making them difficult to carry.

The part that receives the heat of the burning flame is located higher than the flame, but the heat radiation fins that radiate the heat after it is used for power generation tend to be located higher on average than the heat receiving part.

Since heat tends to move upward due to convection, this type of structure is likely to be used to facilitate heat dissipation. In order to support the heat dissipation fins in these high places from below, the size and weight of the device increases.

(Problem to be solved by the invention) To develop a thermoelectric power generation device that is small in size, light in weight, easy to carry, and can be used as a light source, without relying on the conventional structure that is large in size and weight. The purpose is to

(Means for solving the problem) Divide the thermoelectric lamp into a lamp that emits light and a power generating part that generates thermoelectric power. As shown in Figures 1 and 2, the lamp (4) is placed on the base (5), and the thermoelectric power generation module (2) is placed on the external metal plate (3) and the heat dissipation metal plate (1).
) The top surface is the metal plate for heat dissipation of the thermoelectric power generation block (section 3), which is sandwiched between two panels, and the space between the top and bottom is surrounded by the metal plate and glass or transparent plastic/plastic plate 6), and the lamp is Make a container to put it in. At this time, this metal plate and the top heat dissipation metal plate are in close contact with each other to facilitate heat transfer.
It is also connected to the stand on the bottom to form an integrated unit.

Furthermore, on the outer surface of this metal plate, there are heat dissipation fins (7).
will be established.

Additionally, an upper ventilation hole (8) is provided at the top of the device, and a lower ventilation hole (9) is provided at the bottom.

(Function) With the structure shown in Figs. 1 and 2, the outside of the structure that horizontally supports the PH power generation pro 7ri becomes a radiation fin, and the position of the snowy part becomes lower on average.

Therefore, the overall shape is low and the center of gravity is also low, resulting in a small and stable device.

Metal plate and glass plate or transparent plastic with lamp holder, thermoelectric generation block and radiation fins.

If the lamp is placed in an airtight structure using a board, the flame will not fluctuate even in the slightest breeze, allowing stable power output. Even if you attach a sea squirt around the lamp flame without sealing it to prevent wind, a calm will pass between the sea squirt and the heat-receiving metal plate, and stable power generation output will not be obtained. It helps bring in the air needed for combustion, and the top vent helps exhaust hot air after combustion.

A glass plate or clear plastic plate is necessary to allow the lamp's light to escape, and this part can also be moved to provide a place for the lamp to be inserted and removed.

(Example) A power generation lamp as shown in Fig. 1 is made, and a thermoelectric power generation module is used that uses 168 pairs of bismuth-tellurium semiconductors and an internal resistance of 8Ω to obtain a power generation voltage of 8cm and a maximum output of 2W. . Device height: 15cm, weight: approximately 1kg
It is.

Also, if you just want to listen to a small portable radio, you can do it with half the size and one-fourth the weight.

By making the inner surface of the side radiation fins mirror-like, the light from the lamp will be mirrored, increasing the amount of light coming out and enhancing the mood.

If you make the structure as shown in Figure 2 and make the front and back sides transparent,
It can be made to emit light forward and backward.

Even if the shapes are different, if the radiation fins and lamps are the same as those shown in Figure 1, the power generation output will be the same as those shown in Figure 1.

Note that if heat dissipation fins are also provided on the top surface of the thermoelectric generation block, the discharge effect can be further increased, and the output can also be increased.

As for the lamp, a small commercially available kerosene lamp will suffice, but a lamp used on a dining table can also be used as long as it is of an appropriate size.

(Effects of the Invention) As mentioned in the embodiment, a small device weighing about 1 kg, producing an electrical output of about 2 W, and having a height of 15 cm can be achieved. If you listen to a small portable radio (only if you listen to it), if it is about the height of a loam and weighs about 500g,
That's enough.

In this way, this power-generating lamp not only does not take up much space, but is also easily portable and can be used in a wide range of applications.

Continuously run for long periods of time on a small amount of fuel in places without electricity.
It can operate radios, tapes, hooders, LCD televisions, CD players, Trannova, etc.

For disaster prevention, leisure, and mood.
It can also be used in areas without electricity.
