Description

[Technical field]

[0001] The present invention relates to a gas lighting system that uses a fuel containing hydrogen gas. [Background technology]

[0002] Gas lamps were widely used as street lights during the Meiji period. Nowadays, gas lamps are in the spotlight as a scenic element in tourist spots and streets, rather than as a practical lighting fixture, as they create a retro atmosphere. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 05-053024 Summary of the Invention [Problem to be solved by the invention]

[0004] Gas lamps use city gas or liquefied petroleum gas as the combustion gas. For this reason, it is difficult to install gas lamps in areas where there is no piped gas supply such as city gas. On the other hand, even in areas where there is a piped gas supply, construction work is required to lay pipes to the gas lamp installation location, which makes the installation cost high.

[0005] Gas lamps also require frequent maintenance. If the soot on the lamp (glass shade) is not removed, the light intensity will decrease, so gas lamps need to be polished about once a week. The mantle, the light source, also deteriorates, so it needs to be replaced regularly.

[0006] Furthermore, gas lamps are not suitable for indoor lighting because their smoke has an odor and can cause carbon monoxide poisoning. Gas lamps also have the disadvantage that their low illumination makes surrounding residents feel less safe.

[0007] SUMMARY OF THE PRESENT APPLICATION The present invention provides a gas lighting system which has low installation costs, low running costs and overcomes the above-mentioned drawbacks. [Means for solving the problem]

[0008] A first embodiment of the gas lamp system according to the present invention is characterized by comprising a gas supply unit that supplies a combustion gas containing hydrogen gas, and a gas lamp connected to the gas supply unit to combust the combustion gas.

[0009] A second embodiment of the gas lighting system of the present invention is characterized in that in the first embodiment, the gas supply unit comprises a water electrolysis device that electrolyzes water to produce hydrogen gas, and a power supply device that supplies power to the water electrolysis device.

[0010] A third embodiment of the gas lamp system according to the present invention is characterized in that, in the second embodiment, the power supply device is a natural energy power generation unit.

[0011] A fourth embodiment of the gas lamp system of the present invention is characterized in that, in the first embodiment, the gas lamp comprises a burner nozzle for injecting the combustion gas and an illuminant arranged in front of the burner nozzle.

[0012] A fifth embodiment of the gas lamp system according to the present invention is characterized in that, in the first embodiment, the system further comprises a control unit for controlling the turning on and off of the combustion gas. Effect of the Invention

[0013] The gas lamp system of the present invention provides a gas lamp that has low installation costs and low running costs, and can eliminate the drawbacks of the conventional gas lamp. [Brief description of the drawings]

[0014] [Figure 1] 1 is a schematic diagram showing a gas lamp system S according to an embodiment of the present invention. [Diagram 2]FIG. 1 is a schematic diagram illustrating the principle of water electrolysis. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, a gas lamp system S according to an embodiment of the present invention will be described with reference to the drawings. In each drawing, the same components are given the same reference numerals. In the following description, the materials, quantities, dimensions, etc. are merely examples.

[0016] [Gas Lighting System S] FIG. 1 is a diagram showing a gas lamp system S according to an embodiment of the present invention. The gas lamp system S includes a gas lamp 1 and a gas supply unit 10.

[0017] [Gaslight 1] The gas lamp 1 consists of a pole 2 erected from the ground and a lamp 3 placed at the top of the pole 2. The lamp 3 is a shade or globe made of glass, and is provided therein with a burner nozzle 4. The burner nozzle 4 is a device that injects combustion gas G from its tip and burns the combustion gas G. A ceramic gas mantle (light-emitting body) 5 is also provided inside the lamp 3. The gas mantle 5 is a mesh-like device that is disposed on the tip side (forward) of the burner nozzle 4 and emits bright light when exposed to the combustion flame from the burner nozzle 4. Inside the lamp 3, an ignition device (not shown) is also provided.

[0018] A gas supply pipe 6 that supplies combustion gas G toward the burner nozzle 4 is built into the pole 2. One end of the gas supply pipe 6 is connected to the burner nozzle 4, and the other end is connected to a gas supply unit 10.

[0019] [Gas supply unit 10] The gas supply unit 10 is disposed near the pole 2. The gas supply unit 10 includes a water electrolysis device 11, a power supply device 14, and the like. The water electrolysis device 11 electrolyzes water to generate high-purity hydrogen gas and oxygen gas. The water electrolysis device 11 includes a gas tank 12 and a water tank 13 . Water is supplied from the water tank 13 to the water electrolysis device 11, and combustion gas G, which is a mixture of hydrogen and oxygen, is supplied from the water electrolysis device 11 to the gas tank 12. The gas tank 12 is filled with low-pressure combustion gas G, and this combustion gas G is sent toward the gas supply pipe 6.

[0020] FIG. 2 is a schematic diagram showing the principle of water electrolysis (PEM method). There are several types of water electrolysis, including alkaline water electrolysis, proton exchange membrane (PEM) method, anion exchange membrane (AEM) method, and solid oxide method. For example, a proton exchange membrane type is suitable for the water electrolysis device 11. This is because it is only necessary to supply water to the water electrolysis device 11, and only hydrogen and oxygen can be generated. In other words, this is because no carbon monoxide is discharged.

[0021] Proton exchange membranes (proton exchange membranes) are semipermeable membranes, usually made of ionomers, that conduct protons while acting as electronic insulators and reactant barriers, thereby enabling the reaction between oxygen and hydrogen. Water electrolysis using the proton exchange membrane method has advantages such as excellent responsiveness, easy production of high-pressure, high-purity hydrogen, a wide range of operating current densities, and high durability against start-up and shutdown.

[0022] The power supply device 14 supplies power to the water electrolysis device 11 to drive the water electrolysis device 11. The power supply device 14 may be a so-called commercial power supply or a battery power supply, but is preferably a device that generates power from natural energy.

[0023] Natural energy power generation includes solar power generation, wind power generation, hydroelectric power generation, biomass power generation, geothermal power generation, solar thermal power generation, snow and ice heat power generation, and temperature difference heat power generation. It is preferable that the power supply device (natural energy power generation unit) 14 generates electricity from these natural energies depending on the region where the gas lamp 1 is installed.

[0024] The gas lamp system S includes a control unit (not shown) that controls turning on and off the combustion gas G and controls the operation of the water electrolysis device 11. The control unit has a timer and the like, and operates an ignition device and a water electrolysis device 11 in response to sunset and sunrise, thereby automatically turning the gas lamp 1 on and off.

[0025] With this configuration, the gas lamp system S according to this embodiment can be installed in an area without piped gas supply with only simple construction. Since the construction work for laying the pipes can be minimized, the installation cost can be reduced. The Gas Lighting System S does not produce soot from the combustion of hydrogen gas, so there is no need to clean the soot, and maintenance frequency can be significantly reduced. In addition, because a ceramic mantle is used, replacement frequency can be reduced. This allows for reduced running costs. The Gas Light System S can also be used for indoor lighting because it produces no odor when hydrogen gas is burned and does not cause carbon monoxide poisoning. Gas lighting system S uses hydrogen gas, so it has high illuminance and can be used as a security light, improving the sense of security for the surrounding residents.

[0026] The present invention is not limited to the above-mentioned embodiment, and includes various modifications to the above-mentioned embodiment without departing from the spirit of the present invention. In other words, the specific shapes and configurations given in the embodiment are merely examples, and can be modified as appropriate.

[0027] A plurality of gas lamps 1 may be connected to the gas supply unit 10 . A plurality of gas supply units may be connected in parallel to one gas lamp 1. The gas tank 12 may be filled with hydrogen produced from fossil fuels or hydrogen produced by reforming methane gas or the like (steam reforming method).

[0028] The gas supply unit 10 may generate hydrogen by a chemical hydride method. The chemical hydride method is a method in which hydrogen is fixed as a cyclic organic compound such as methylcyclohexane (MCH) or sodium borohydride (SBH) by a hydrogenation reaction of an aromatic compound such as toluene, stored and transported in a liquid state at room temperature and pressure, and hydrogen is extracted and utilized by a dehydrogenation reaction.

[0029] The gas lamp 1 may be an open flame without the gas mantle 5 . The gas lamp 1 is not limited to being installed outdoors, but may also be installed indoors. [Explanation of symbols]
