Method for energy mutual conversion power generation using chemical reaction by mixture of light-emitting diode (LED) and excellent conductor

Abstract

To solve the issue that an existing photoelectric effect power generator such as a solar cell uses a light source outside a device and thus cannot generator power during the night when light energy for power generation is not available.SOLUTION: A light-emitting diode (LED) having a material characteristic of the mutual conversion action between electric energy and light energy and one of a conductive metal such as copper and aluminum and a carbon-based excellent conductor such as a carbon allotrope are processed in powders or in a solution and are mixed in an appropriate ratio and amount. The mixture is sealed in a power generator, and electricity is provisionally flown from an external power source to the mixture or light is applied on the mixture from an external light source. After that, the mixture becomes in a state in which light emission and power generation occur at the same time (a state in which the mutual conversion between the electric energy and the light energy is being performed). The problem is solved by a method for power generation using the chemical reaction (the energy mutual conversion action) of the "the mixture of a light-emission diode (LED) and an excellent conductor".SELECTED DRAWING: None

Summary of the Invention

Problems to be Solved by the Invention

[0007] Conventional photovoltaic power generation devices such as solar cells generate electricity by utilizing the light energy of a light source outside the device. Therefore, there is a problem that they cannot generate electricity when the light energy required for power generation cannot be obtained, such as at night or on rainy days.

Means for Solving the Problems

[0008] A light-emitting diode (LED) having the material characteristic of the mutual conversion action between electrical energy and light energy, and a highly conductive metal such as copper or aluminum, or a carbon-based good conductor such as a carbon allotrope are processed into a powder form or a solution form, and mixed in an appropriate amount and ratio so that there is no bias in the constituent materials. (If the chemical composition of the target substance is the same, the state such as solid or liquid is not limited) This mixture is enclosed in a power generation device, and electrical energy is temporarily supplied (energized) from an external power source, or light energy is supplied (irradiated) from an external light source. As a result, the mixture enters a state where light emission and power generation occur simultaneously within the device (a state in which mutual conversion between electrical energy and light energy takes place). This method of generating electricity by utilizing the chemical reaction (energy interconversion) between a mixture of light-emitting diodes (LEDs) and good conductors solves the problem. Furthermore, this method can be applied not only as a power generation device (power source) but also as a light source, such as in lighting devices. In the chemical reaction of this mixture (the interconversion of electrical energy and light energy), the two energies are not 100% interconverted; some of the electrical energy is converted into thermal energy instead of light energy. Since the converted thermal energy is not converted back into electrical energy, the power generation efficiency as a power source decreases accordingly. To address this challenge, the power generation device is manufactured using the same method after adding appropriate amounts of materials with pyroelectric effects (interconversion between electrical and thermal energy), such as pyroelectric materials, organic compounds, and soil and rocks, to the initial mixture (light-emitting diodes (LEDs) and good conductors). This allows not only light energy but also thermal energy to be converted into electrical energy, thus solving the problem of reduced power generation efficiency.

Claims

1. There is a type of semiconductor diode called a light-emitting diode (LED), which is used as a light source in lighting devices. This material has the property of "emitting light when voltage is applied (current is passed through it), and generating electromotive force when light is shone on it." This means that light-emitting diodes have the ability to convert between electrical energy and light energy. This light-emitting diode and highly conductive metals such as copper and aluminum, or carbon-based good conductors such as carbon allotropes, are processed into powder or solution form and mixed in appropriate amounts and ratios, ensuring that there is no imbalance in the constituent materials. (As long as the chemical composition of the substances in question is equivalent, the state of the substance, such as solid or liquid, is not limited.) This mixture is sealed inside the power generation device, and electrical energy is temporarily supplied from an external power source (energy flow), or light energy is supplied from an external light source (irradiation). As a result, the mixture enters a state where light emission and power generation occur simultaneously within the device (a state in which mutual conversion between electrical energy and light energy takes place). This method of generating electricity utilizes the chemical reaction (energy interconversion) between a mixture of light-emitting diodes (LEDs) and good conductors. When this mixture with power generation capabilities is used as a power source for electrical appliances, its state (solid, liquid, etc.) is not limited. Furthermore, the shape and material of the outer casing of the power generation device (such as a battery) in which the mixture is enclosed are not limited, and the mixture does not even need to be enclosed inside the power generation device. This also includes cases where a solution-formed mixture is applied directly to the inside of an electrical appliance, like a paint, and then connected to wires, circuits, etc. (Light-emitting diodes (LEDs) come in several types depending on the raw materials used, such as gallium and indium, but all those with equivalent material properties are included.)

2. In the method described in claim 1, electricity is generated by a chemical reaction of the mixture (interconversion of electrical energy and light energy), but the chemical reaction that occurs in the device does not result in 100% interconversion of electrical energy and light energy. Within the device, electrical energy is generated, transmitted to good conductors, and circulated, during which some of it is converted into thermal energy rather than light energy. When the mixture inside the device is converted into thermal energy other than electrical and light energy, the power generation efficiency (efficiency of generating electrical energy) as a power source decreases. Therefore, to address this problem, an appropriate amount of a substance having a pyroelectric effect (interconversion of electrical energy and thermal energy), such as a pyroelectric material, organic compound, or soil and rock, processed in powder or solution form, is added to the initial mixture (light-emitting diode (LED) and good conductor), mixed so as to ensure that there is no bias in the constituent materials, and a power generation device is manufactured in the same manner as described in claim 1. This allows the thermal energy generated in the mixture to be converted into electrical energy, improving power generation efficiency (the efficiency of generating electrical energy). This method suppresses the decrease in power generation efficiency (electrical energy generation efficiency) of a power generation device by creating a cycle in which light energy and thermal energy are converted into electrical energy, and electrical energy is converted back into light energy and thermal energy, through the combination of materials that have a pyroelectric effect.

3. A power generation device and a power source using the method according to claim 1 or claim 2.

4. A lighting device and light source using the method according to claim 1 or claim 2.

5. A display, video output device, and video projection device using the method according to claim 1 or claim 2.

6. Power generation equipment, communication equipment, data centers, transportation vehicles such as passenger cars, defense equipment, home appliances such as TVs, computers, printed circuit boards, semiconductors, integrated circuits, mobile devices (smartphones, e-readers, tablet devices, etc.), mobile routers, mobile batteries, digital cameras (including flash functions), office automation equipment such as copiers and scanners, medical equipment such as diagnostic imaging devices, other lights used for purposes other than lighting functions such as hazard lights and turn signals, warning lights for emergency vehicles, construction lights for nighttime construction, decorative lights such as illuminations, VR devices (goggles, projectors, etc.), AR devices (glasses, projectors, etc.).

7. Services and businesses using the power generation equipment, communication equipment, data centers, transportation vehicles such as passenger cars, defense equipment, home appliances such as TVs, computers, printed circuit boards, semiconductor integrated circuits, mobile devices, mobile routers, mobile batteries, digital cameras, office automation equipment, medical equipment, and other lighting equipment, warning lights, construction lights, decorative lights, VR devices, and AR devices as described in claim 6.
