<Embodiment 1>
<Embodiment 1: Overview>

Embodiment 1 is an illuminating device in which a light emitting unit and a power unit are configured to be detachable using a magnet.
<Embodiment 1: Configuration>

The lighting device of the present embodiment is a lighting device including a light emitting unit that emits light, and a power unit that is configured to be detachable from the light emitting unit and supplies power in an insulated state, and the light emitting unit includes a light emitting unit, The power supply unit includes a power supply unit, a magnetoelectric conversion unit, and a light emitting unit side coupling unit, and the power unit includes a power receiving unit, an electromagnetic conversion unit, and a power unit side coupling unit.
<Description of Each Configuration of Embodiment 1>
<Whole lighting device>

FIG. 1 is a perspective view showing an example of the appearance of the illumination device of the present embodiment. As shown in FIG. 2, the “lighting device” includes a light emitting unit (0201) and a power unit (0202) configured to be detachable from the light emitting unit and supplying power in an insulated state. The light emitting unit is a unit including an illumination light source, and the power unit plays a role of supplying electric power thereto. Moreover, both are comprised so that attachment or detachment is possible, and it is comprised so that both may be in an insulated state.
<Each light emitting unit configuration>

  FIG. 3 is an example of a functional block diagram of the lighting apparatus according to the first embodiment. Each configuration of the light emitting unit (0301) will be described with reference to FIG.

    The “light emitting unit” (0303) has a configuration in which a plurality of light emitting diodes are arranged. A light emitting diode is a diode that emits light when a voltage is applied. For example, as shown in the front view of the illuminating device in FIG. 4, the light emitting diode units (0401) are arranged in three rows, and 45 units are arranged in a total of 13 units, 19 units, and 13 units in each row. It is possible. FIG. 5 shows an example of the configuration of the light emitting diode unit. The light emitting diode unit is configured, for example, by connecting one to several light emitting diodes (0502) in series on a printed circuit board (0501). . Further, a surface emitting LED (0504) may be connected to the printed circuit board (0503). For example, as an example of an arrangement in a small illuminating device, as shown in FIG. 6, it is conceivable to arrange three units of light emitting diode units (0601) in two rows. The color is typically white, but is not limited thereto. Various colors can be adopted. However, when it is used in an aquarium, it is necessary to select a color that does not adversely affect the growth of aquatic plants and animals such as fish bred in the aquarium. The color temperature is in the range of about 2000K to 8000K. As a configuration other than the light emitting diode, for example, a protection structure for protecting the light emitting diode from the external environment is provided. For example, when it is placed in water, it is protected by a watertight structure, and light emitted from the light emitting diode is radiated to the outside through watertight glass. Further, a color liquid crystal panel may be disposed between the glass and the arrangement of the light emitting diodes. In this case, the color of the illumination can be changed by controlling the color liquid crystal panel with an external signal.

    Glass can be replaced with transparent plastic. Furthermore, since the light from the light emitting diode is highly linear, a diffusion plate may be disposed in front of the light emitting diode so that the light is diffused throughout. In this case, you may comprise so that the transparent plastic plate replaced with the above-mentioned glass may serve as a diffuser plate.

    Reference is now made to FIG. FIG. 7 is an example of a cross-sectional view of the lighting apparatus according to the first embodiment. In the light emitting unit (0701), the above-described light emitting diode units (0702) are arranged, and the diffusion plate (0703) is arranged. The light emitting unit side circuit (0708) includes a power supply unit. The power unit side circuit (0709) includes a power reception unit. Note that the opening (0704), the radiation fin (0705), the housing (0706), and the polyurea resin layer (0707) of the light emitting unit shown in this figure will be described later.

  Here, FIG. 3 will be referred to again.

  The “power supply unit” (0304) supplies power to the light emitting unit. The power supply unit is configured to receive electric power from a magnetoelectric conversion unit, which will be described later, and supply this to the light emitting unit. The electric power may be configured to be received from other than the magnetoelectric conversion unit. For example, a rechargeable battery may be provided, and the power stored in the battery may be temporarily used when the power from the magnetoelectric conversion unit cannot be received. Further, a solar battery or the like may be provided, and power may be obtained from sunlight or room lighting. When the light emitting unit is a light emitting diode, it is configured to supply direct current. Further, a voltage stabilization circuit may be provided so that a voltage to be supplied becomes a predetermined value, or a noise reduction circuit for performing power supply with as low noise as possible may be provided.

  The “magnetoelectric conversion unit” (0305) magnetoelectrically converts the electromagnetic wave received from the power unit and outputs it to the power supply unit. Specifically, current is generated by the principle of electromagnetic induction in accordance with the change of the magnetic field due to the electromagnetic wave by the coil (feeding coil) of the magnetoelectric conversion unit. Then, the generated current is output to the power supply unit. The magnetoelectric conversion unit has a magnetic core, and constitutes a coil by winding an electric wire around the magnetic core. The magnetic core has, for example, a substantially U shape, and is typically configured such that one end and the other end are arranged substantially perpendicular to the joint surface with the power unit. However, it is not limited to this. The magnetoelectric conversion unit may be composed of not only one magnetic core but also two magnetic cores, that is, two magnetic cores. In this case, a configuration in which substantially U-shaped magnetic cores are combined so as to form a substantially cross when observed from the side of the joint surface with the light emitting unit will be common. The material of the magnetic core is preferably a soft magnetic material having a high magnetic permeability. For example, an alloy such as permalloy.

  The “light emitting unit side coupling portion” (0306) includes a magnet for coupling the light emitting unit directly or indirectly to the power unit so that the electromagnetic coupling with the power unit can be performed by the magnetoelectric conversion unit. . For example, if an alloy magnet having neodymium, iron, or boron as a main component is used for bonding, a mechanical bonding structure is unnecessary, and the boundary surface can be made smooth with no irregularities. For example, if it is used in combination with a screw-in type, it can be more reliably coupled. Here, “directly coupled” refers to a case where the light emitting unit is in close contact with the positional relationship where electromagnetic waves can be received from the power unit. The term “indirectly coupled” refers to, for example, a case where materials or spaces such as glass, acrylic, paper, and the like are bound to each other. Included in the bond.

Further, magnets for positioning may be arranged on the light emitting unit side and the power unit side. For example, as shown in FIG. 8, if the magnet (0801) of the light emitting unit side coupling portion is arranged so as to be inside the polygon formed by the magnet (0802) of the power unit side coupling portion, the attracting force of the magnets is increased. By interacting, the light emitting unit and the power unit can be coupled in a desired relative positional relationship. The magnet on the light emitting unit side may be on the outside. For example, a ferrite magnet may be used as this magnet.
<Each component of the power unit>

  Here, with reference to FIG. 3 again, each configuration of the power unit (0302) will be described.

    The “power receiving unit” (0307) receives an external power source. A power supply of 100V for home use or 200V for industrial use is assumed. However, it is not limited to this. The power receiving unit receives power from these power sources in a wired manner. However, it may be received wirelessly or configured to be received from a battery or the like. Moreover, it may be configured to receive from a solar cell, a fuel cell, or the like, or may be configured to receive power from a battery such as a hybrid car, a generator connected to a ship engine, or the like.

  The “electromagnetic conversion unit” (0308) converts the received power into an electromagnetic wave and sends it to the magnetoelectric conversion unit of the light emitting unit. Specifically, it is configured to generate an electromagnetic wave by passing an alternating current through a coil (power receiving coil) of the electromagnetic conversion unit. The electromagnetic conversion part has a magnetic core, and constitutes a coil by winding an electric wire around the magnetic core. This magnetic core has, for example, a substantially U-shape, and is typically configured such that one end and the other end are arranged substantially perpendicular to the joint surface with the light emitting unit. However, it is not limited to this. The electromagnetic conversion unit may be constituted by not only one magnetic core but also two magnetic cores, that is, two magnetic cores. In this case, a configuration in which substantially U-shaped magnetic cores are combined so as to form a substantially cross when observed from the side of the joint surface with the light emitting unit will be common. The material of the magnetic core is preferably a soft magnetic material having a high magnetic permeability. For example, an alloy such as permalloy.

The “power unit side coupling portion” (0309) includes a magnet for coupling directly or indirectly to the light emitting unit so that the electromagnetic conversion portion can be electromagnetically coupled to the light emitting unit. For example, if an alloy magnet having neodymium, iron, or boron as a main component is used for bonding, a mechanical bonding structure is unnecessary, and the boundary surface can be made smooth with no irregularities. For example, if it is used in combination with a screw-in type, it can be more reliably coupled. “Directly coupled” means that the light emitting unit is in close contact with the positional relationship where electromagnetic waves can be received from the power unit. “Indirectly coupled” means, for example, glass, acrylic, paper, etc. This refers to the case where the materials or spaces are combined, and if they are in a positional relationship where electromagnetic waves can be received from the power unit, they are configured in the same manner as the light-emitting unit-side coupling portion, even if they are not in close contact.
<Embodiment 1: Effect>

  According to the illuminating device of the present invention, it is possible to provide an illuminating device that is free from restrictions on the design of the aquarium. In addition, since the lighting device of the present invention is coupled with a magnet, even if the position of the light emitting unit disposed inside the aquarium is shifted due to fish picking, the power unit disposed outside the watertight wall of the aquarium is also a magnet. The relative positional relationship is corrected because it moves by the attractive force of.

In addition, the power unit and the light emitting unit may be arranged and used in water in a state where they are coupled together. In this case, there is an effect that the replacement work accompanying the deterioration of the light emitting unit can be easily performed. This embodiment is not limited to use in water, but is suitable as an outdoor lighting device.
<Embodiment 2>
<Embodiment 2: Overview>

The second embodiment is an illuminating device that is based on the first embodiment, and that double-shields the light emitting unit side coupling portion and the power unit side coupling portion with an external magnetic core.
<Embodiment 2: Configuration>

The lighting device according to the present embodiment includes a light emitting unit and a power unit. The light emitting unit includes a light emitting unit, a power supply unit, a magnetoelectric conversion unit, and a light emitting unit side coupling unit. This embodiment is common to Embodiment 1 in that it includes a power reception unit, an electromagnetic conversion unit, and a power unit side coupling unit. And it has the characteristics in the structure of the magnetoelectric conversion part by the side of a light emission unit, and the electromagnetic conversion part by the side of a power unit. This characteristic part will be described below. The other parts are the same as those in the first embodiment, and thus the description thereof is omitted.
<Description of Each Configuration of Embodiment 2>
<Description of magnetoelectric conversion part of light emitting unit>

    FIG. 9 is a conceptual diagram illustrating a light emitting unit side coupling portion of the lighting apparatus according to Embodiment 2 and a magnetoelectric conversion unit provided in the light emitting unit. In addition, it shows about each part on the power unit side. First, the configuration of the magnetoelectric conversion unit of the light emitting unit will be described with reference to FIG.

  The “magnetoelectric conversion unit” includes a light emitting unit side internal magnetic core (0901) including a coil, a first external magnetic core (0902), and a second external magnetic core (0903).

  The “first external magnetic core” is an external magnetic core, and is a cup-shaped magnetic core that houses at least a part of the magnet of the light emitting unit side coupling portion and is concealed on the interface with the power unit. The cup shape is not particularly limited. The drinking cup may have a round coffee cup shape, or may have a shape like a main body or lid of a square lunch box as shown in FIG. The material is preferably a high magnetic permeability material. For example, iron alloys such as permalloy. The boundary surface with the power unit is a surface on the side that forms a boundary when the power unit is magnetically coupled, and is specifically a plate-like member made of a nonmagnetic material such as a plastic material. This member will be referred to as a light emitting unit lid member (0904). The light emitting unit lid member and the first external magnetic core are configured to protect and protect the magnet (0905) of the light emitting unit side coupling portion from the external environment.

The “second external magnetic core” is an external magnetic core, and is a cup-shaped magnetic core that further accommodates the first external magnetic core and the light emitting unit side internal magnetic core and is concealed by the boundary surface. Here, the “boundary surface” is the light emitting unit lid member described above. The “external magnetic core” is a magnetic body that covers the coil. The first and second external magnetic cores cover the coil provided on the light emitting unit side internal magnetic core. By covering the periphery of the coil, the magnetic lines of force are concentrated on the magnetic body constituting the magnetic core, the magnetic lines of force can be less likely to leak to the outside, and the magnetic flux density of the magnetoelectric conversion unit can be increased. In addition, since the second external magnetic core is configured to cover the first external magnetic core, the second external magnetic core is also configured to cover the magnet of the light emitting unit side coupling portion, and also has a function of protecting these structures from being isolated from the external environment. . In addition, although the coil which is a magnetoelectric conversion part exists in the area | region between the 1st external magnetic core and the 2nd external magnetic core, it is good also as a structure which fills the area | region where this coil exists with an insulating liquid etc. Good. In this case, the occurrence of sparks can be suppressed more than when the area is filled with air, and the overall density can be increased, so that the buoyancy is reduced when the light emitting unit of the lighting device is placed in water. be able to. If the buoyancy can be reduced, the light emitting unit is less likely to float in water, so that the coupling force with the power unit can be designed to be relatively weak.
<Light emitting unit side internal magnetic core>

As described above, the light emitting unit side internal magnetic core is disposed in a closed space constituted by the first external magnetic core, the second external magnetic core, and the light emitting unit lid member of the light emitting unit. One end portion of the light emitting unit side internal magnetic core is disposed so that the magnetic field lines are incident on the light emitting unit lid member in the normal direction of the boundary surface with the power unit. These magnetic field lines are radiated from the power unit side internal magnetic core. Similarly, the other end portion of the light emitting unit side internal magnetic core is arranged so that the magnetic lines of force are incident in the normal direction of the boundary surface with the power unit. The point that these lines of magnetic force are radiated from the inner core on the word unit side is the same as described above. As a material of the light emitting unit side internal magnetic core, a high permeability material is also used. It is an iron-based alloy such as permalloy. Further, an electric wire is wound around the light emitting unit side internal magnetic core to form a coil. An electromagnetic field change inputted from the power unit is taken out as electric power by this coil. In order to take out as electric power, a hole for taking out electric power is provided in a part of the second external magnetic core, and a power line or the like is led from the hole to be used for the light emitting unit. This hole may be sealed with a sealing material or the like. In addition, when adjusting the electric power taken out by the light emitting unit under the control of the power unit, the coil (0906) for the electric power provided to the light emitting unit in the light emitting unit and the electric power used by the control circuit in the light emitting unit, etc. The control power coil (0907), which is a coil, may be configured separately. That is, it is conceivable that the light emitting unit coil and the control circuit coil are separately and independently wound around the light emitting unit side internal magnetic core.
<Configuration of electromagnetic conversion part of power unit>

FIG. 9 is a conceptual diagram illustrating a power unit side coupling unit and an electromagnetic conversion unit provided in the power unit of the lighting apparatus according to the second embodiment. As described above, each part on the light emitting unit side is also shown. The configuration of the electromagnetic conversion unit of the power unit will be further described with reference to FIG.
<Description of electromagnetic converter>

    The “electromagnetic conversion unit” includes a power unit side internal magnetic core (0908) including a coil, a third external magnetic core (0909), and a fourth external magnetic core (0910).

    The “third external magnetic core” is an external magnetic core, and is made of a plastic that is a non-magnetic material that houses at least a part of the magnet of the power unit side coupling portion and forms a boundary surface with the light emitting unit. It is a cup shape that is concealed by the power unit lid member (0911). The cup shape is not particularly limited, the material is preferably a high permeability material, and the power unit side coupling member and the third external magnetic core are used to isolate and protect the magnet (0912) of the power unit side coupling portion from the external environment. Are configured in the same manner as the light emitting unit side magnetoelectric conversion unit.

    Further, the edge of the third external magnetic core that covers the power unit cover member may be configured so that the first external magnetic core of the light emitting unit just overlaps the edge of the light emitting unit cover member. This is because the magnetic flux generated in the third external magnetic core on the power unit side can be smoothly transmitted to the first external magnetic core of the light emitting unit.

  The “fourth external magnetic core” is an external magnetic core, and has a cup shape in which the third external magnetic core and the power unit side internal magnetic core are accommodated inside and are concealed on the boundary surface. Here, the “boundary surface” is the aforementioned power unit lid member. The “external magnetic core” is a magnetic body that covers the coil, and the third and fourth external magnetic cores cover the coil provided on the power unit side internal magnetic core. Since the external magnetic core is configured to cover the third external magnetic core, it is also configured to cover the magnet of the power unit side coupling portion, and also has the function of isolating and protecting these structures from the external environment. In the region between the external magnetic core and the fourth external magnetic core, there is a coil that is a magnetoelectric conversion unit, but the region where this coil exists may be filled with an insulating liquid, etc. The light emitting unit side magnetoelectric conversion unit is configured similarly.

Further, the edge of the fourth external magnetic core that covers the power unit lid member may be configured so that the second external magnetic core of the light emitting unit just overlaps the edge that covers the light emitting unit lid member. This is because the magnetic flux generated in the fourth external magnetic core on the power unit side can be smoothly transmitted to the second external magnetic core of the light emitting unit.
<Overall of the first to fourth external magnetic cores>

    Furthermore, the magnet of the light emitting unit side coupling portion and the magnet of the power unit side coupling portion are configured to be doubly covered by the first to fourth external magnetic cores. That is, as shown in FIG. 8, the magnets (0803, 0804) of the light emitting unit side coupling portion are composed of the first external magnetic core (0806) covering the periphery of the light emitting unit side internal magnetic core (0805) and the second external It is covered with a magnetic core (0807). Therefore, the magnetism generated from the magnet for coupling can be shielded. This is important for use in lighting such as aquariums that contain organisms that are susceptible to magnetic effects.

For example, it is conceivable to arrange a member for holding the magnet in the first external magnetic core. In FIG. 9, a magnet holding structure (0913, 0913) made of an aluminum member is illustrated. This magnet holding structure is provided with a margin for allowing the magnet to be held with a margin. In order to protect the magnet from vibrations generated when fish is caught, a buffer material or the like may be disposed in this marginal area. This is because some magnets are fragile. It is also conceivable to cover the light emitting unit and the power unit with a conductor such as an aluminum casing. In these cases, external leakage of the dynamic magnetic field generated by the power unit side coil (power receiving coil) and the light emitting unit side coil (power feeding coil) can be further reduced.
<Power unit side internal magnetic core>

As described above, the power unit side internal magnetic core is disposed in a closed space formed by the third external magnetic core, the fourth external magnetic core, and the power unit lid member of the power unit. One end of the power unit side internal magnetic core is arranged so that the magnetic field lines radiate in the normal direction of the boundary surface with the light emitting unit with respect to the power unit lid member. This line of magnetic force is used for magnetoelectric conversion by the light emitting unit side internal magnetic core. Similarly, the other end of the power unit side internal magnetic core is also arranged so as to radiate magnetic lines in the normal direction of the boundary surface with the light emitting unit. This magnetic field line is used in the light emitting unit as described above. As the material for the power unit side internal magnetic core, a high permeability material is also used. It is an iron-based alloy such as permalloy. Further, an electric wire is wound around the power unit side internal magnetic core to form a coil. This coil outputs a magnetic force to the light emitting unit. In order to pass an electric current through the coil, a wire drawing hole is provided in a part of the fourth external magnetic core, and a power line or the like is led from the hole to be used for the power unit. This hole may be sealed with a sealing material or the like.
<Embodiment 2: Effect>

  In the present embodiment, since the leakage of the magnetic field can be suppressed, the possibility of affecting the ecology of fish and birds in the aquarium can be reduced. The reason is as follows. A small piece of calcareous stone or sand in the otocyst or inner ear of an animal is called an otolith, which is said to be involved in the sense of balance. Research has shown that there is a high possibility that birds and fish have magnetic otoliths in their otolith tools, which can play a role of navigator by detecting geomagnetism. Therefore, the magnetic field generated by the magnet or coil may affect the fish otolith. However, since this influence can be reduced in the present embodiment, it is suitable for illumination of an environment in which this kind of organism is raised.

Further, in this embodiment, if the magnet is configured to be double-shielded by the first to fourth external magnetic cores with almost no gap, it is possible to further reduce the leakage of the magnetic field. The risk of giving off can be reduced.

  The “power unit control unit” controls the light emitting unit. For example, only a part of the light-emitting diodes arranged in the light-emitting section is lit, or when there are multiple types of light-emitting colors, the light-emitting color is controlled, blinking, illuminance is changed, or the light-emitting unit Control is performed so that the constant of the internal circuit on the side is changed, or the operation of the internal circuit of the light emitting unit is stopped or activated. The power unit side circuit (0709) of FIG. 7 further includes this power unit side control unit.

The “power unit side transmission / reception unit” has infrared communication means for performing input / output from a power unit lid member which is an attachment / detachment boundary surface with the light emitting unit in order to communicate with the light emitting unit. As a signal output from the power unit side transmission / reception unit to the light emitting unit side transmission / reception unit, for example, a control signal for the power unit control unit to control the light emission unit can be considered. As a signal input from the light emitting unit side transmission / reception unit to the power unit side transmission / reception unit, for example, a signal indicating the operation status of the above-described light emitting unit can be considered. Infrared rays are electromagnetic waves having a wavelength longer than that of red light which is visible light, but it is preferable to use near infrared rays as a communication means. A part of the power unit lid member may be transparent so as to transmit infrared rays. Note that if infrared rays are used for transmission and reception, it is possible to reduce adverse effects on fish and birds due to external radiation. This is because light is highly straight. In addition, even if there is a glass wall of the water tank between the power unit and the light emitting unit, it is convenient because it can transmit infrared light. On the other hand, it is also conceivable to use radio waves instead of infrared light. In this case, the problem due to external radiation remains, but it is excellent in that signals can be exchanged even if the power unit and the light emitting unit are slightly deviated. Moreover, it is also possible to use sound waves or visible light instead of radio waves or infrared light.

For example, a voltage detector can be considered, and the measured value of the degradation value can be cited. FIG. 14 is an example of a line graph schematically showing changes in applied voltage and acquired power over time when the lighting apparatus according to Embodiment 5 is used. When the component deteriorates, the resistance value increases. The increase in the resistance value should be described by a natural logarithmic function, but was assumed to be approximated linearly, assuming that it would be a problem to decay in a short period (less than 1/2 of the element lifetime). Then, in the potential difference E, current I, and resistance R, the current in unit time t is
Than,
And change.
On the other hand, the brightness P actually obtained is
Than,
And change. That is, in the case of constant current control, it is assumed that the luminance changes according to changes in voltage and resistance. Therefore, it is only necessary to calculate the brightness that can be obtained according to P = IE between the voltage to be applied and the resistance value that actually deteriorates.

  It is also conceivable to directly control the acquired brightness as a deterioration value using an optical sensor. In this case, the control is performed according to the sum of changes in voltage and resistance. In this case, a line graph schematically showing changes in applied current and acquired power over time is as shown in FIG.

That is, for example, when the deterioration value is equal to or less than the threshold, the power supply voltage supplied from the power supply unit to the light emitting unit is boosted. In addition, it is conceivable to put the deterioration value x into the function y = f (x) and control it to the calculated voltage value y.

The voltage value detected from the light emitting diode by the voltage detector is temporarily stored in a RAM (main memory) periodically. In accordance with a determination program developed on a RAM (main memory), the CPU determines that the voltage value is equal to or less than a certain value. When it is determined that the value is below a certain value, the CPU calculates a power supply voltage value after the change corresponding to the voltage value acquired as the deterioration value in accordance with a control program developed on the RAM (main memory). I do. Specifically, the CPU calculates, for example, a power supply voltage value or / and a power supply current value from a relation table or function.

<Each component of the heat recovery unit>

  The “heat recovery unit” includes a high temperature member (1711), a low temperature member (1712), a thermoelectric generator (1713), and a regenerative power sending means (1714).

For example, copper, aluminum, iron, stainless steel and the like are not limited thereto, but high thermal conductivity ceramics such as boron nitride ceramics, alumina ceramics, titanium carbide ceramics, and titanium oxide ceramics may be used. Alternatively, for example, if a silicone gel having high thermal conductivity is used, the substrate of the light emitting diode and the substrate of the thermoelectric generator can be brought into close contact with each other, and the temperature can be efficiently increased by the heat of the substrate of the light emitting diode.

  The “low temperature member” has a relatively low temperature depending on the environmental temperature. “Environmental temperature” refers to the temperature around a low temperature member such as room temperature or water temperature. Relatively low temperature means that the temperature is lower when compared to the elevated temperature of the high temperature member. For example, as shown in FIG. 7, if the opening (0704) is provided around the low temperature member so that water or air can pass therethrough, the relative low temperature of the low temperature member can be maintained. Since heated water and air rise, it is preferable that the opening is directed up and down so that water and air can pass in the vertical direction.

  The “thermoelectric generator” generates power using the temperature difference between the high temperature member and the low temperature member. That is, when there is a temperature difference between two types of metal, electric power is generated by utilizing a phenomenon (Seebeck effect) in which a potential difference is caused by the movement of metal free electrons to the low temperature side and the remaining metal ions to the high temperature side. . For example, it is conceivable to use a Peltier element.

The “regenerative power sending means” sends the power generated by the thermoelectric generator to the power supply unit. However, it may be sent to other than the power supply unit. For example, it may be sent to a battery and regenerative power may be stored in the battery.
