[0012] Hereinafter, a lighting system according to the present embodiment and a lighting device used in the lighting system will be described in detail with reference to the drawings.

[0013] The lighting system 1 according to this embodiment includes a lighting device 10 and a small air vehicle (unmanned air vehicle) 20.

[0014] The lighting device 10 can be used as a road light, street light, etc. that illuminates roadways, sidewalks, parks, parking lots, forest roads, etc.

[0015] In this embodiment, the lamps are installed at a predetermined interval along the driving line on both sides of a roadway 100, and are used as road lights that illuminate a road surface 100a of the roadway 100 (see FIG. 1).

[0016] The lighting device 10 includes a lighting fixture 120 capable of emitting light, and a pole (fixing member) 110 to which the lighting fixture 120 is fixed.

[0017] Furthermore, in this embodiment, the lighting device 10 is provided with a landing pad 130 on which the miniature aircraft 20 lands, and this landing pad 130 has a landing surface 130a on which the miniature aircraft 20 lands (see FIG. 3).

[0018] In this embodiment, the landing pad 130 has a rectangular plate shape, and is disposed on the upper part of the lighting fixture 120. The upper surface (flat surface) of the landing pad 130 serves as a landing surface 130a on which the miniature aircraft 20 lands.

[0019] The landing platform 130 is provided with a first electromagnet device 131 capable of generating a magnetic force from the landing surface 130a (see FIG. 3).

[0020] As described above, the lighting system 1 includes the miniature aircraft 20. In this embodiment, the miniature aircraft 20 includes a main body 210, legs 220 extending downward from the main body 210, an arm 230 extending horizontally outward from the main body 210, and a propeller 240 attached to the arm 230.

[0021] However, the shape of the miniature flying object is not limited to this shape, and it is possible for the miniature flying object to have various shapes, such as an airplane-type miniature flying object.

[0022] The miniature aircraft 20 is provided with a second electromagnetic device 211 capable of generating a magnetic force. In this embodiment, the second electromagnetic device 211 is built into the main body 210 of the miniature aircraft 20 (see FIG. 3).

[0023] Then, by generating magnetic forces in the first electromagnet device 131 and the second electromagnet device 211 that attract each other, the miniature aircraft 20 is fixed to the landing surface 130a.

[0024] In this manner, in this embodiment, the miniature aircraft 20 is fixed to the landing surface 130a by generating a mutually attractive magnetic force between the miniature aircraft 20 and the landing pad 130. This makes it easier to fix the miniature aircraft 20 to the landing pad 130.

[0025] Furthermore, in this embodiment, since electromagnetic devices are incorporated into both the miniature aircraft 20 and the landing pad 130, the miniature aircraft 20 can be fixed to the landing pad 130 more firmly.

[0026] In this embodiment, each of the miniature aircraft 20 and the landing pad 130 has the function of controlling magnetic force.

[0027] 3, the control unit 132 is provided on the landing pad 130, and the control unit 212 is provided on the miniature aircraft 20. The control unit 212 is also built into the main body 210 of the miniature aircraft 20.

[0028] In this manner, in this embodiment, at least one of the miniature aircraft 20 and the landing pad 130 has a function of controlling the magnetic force. This makes it possible to control the magnetic force so that the magnetic force of attraction between the first electromagnet device 131 and the second electromagnet device 211 is smaller than the lift force of the miniature aircraft 20. This allows the miniature aircraft 20 to be in a state in which it can take off from the landing pad 130.

[0029] In addition, each of the miniature aircraft 20 and the landing pad 130 has a function of controlling magnetic force. This allows the first electromagnet device 131 and the second electromagnet device 211 to be controlled to have magnetic forces that repel each other. In this way, the mutually repulsive magnetic forces assist the miniature aircraft 20 in taking off from the landing pad 130, making it easier for the miniature aircraft 20 to take off from the landing pad 130.

[0030] In this manner, in this embodiment, when the miniature aircraft 20 lands on the landing surface 130a of the landing pad 130, the first electromagnet device 131 and the second electromagnet device 211 are controlled to generate magnetic forces that cause the magnetism (magnetic poles) to attract each other. By generating magnetic forces that cause the magnetism (magnetic poles) to attract each other, the miniature aircraft 20 can be fixed to the landing pad 130.

[0031] On the other hand, when the miniature aircraft 20 is made to take off (fly away) from the landing pad 130, the first electromagnet device 131 and the second electromagnet device 211 are controlled to generate magnetic forces so that the magnetism (magnetic poles) repel each other. By generating magnetic forces so that the magnetism (magnetic poles) repel each other, the magnetic forces assist the miniature aircraft 20 in taking off (flying away) from the landing pad 130.

[0032] In addition, when controlling the first electromagnet device 131 and the second electromagnet device 211 to make the miniature aircraft 20 take off (fly away) from the landing pad 130, it is not necessary to generate magnetic force so that the magnetism (magnetic poles) repel each other. For example, by controlling the first electromagnet device 131 and the second electromagnet device 211 to adjust the magnetic force so that the magnetic force that attracts each other is smaller than the lift force of the miniature aircraft 20, the miniature aircraft 20 can be taken off (fly away) from the landing pad 130. In addition, it is also possible to make the miniature aircraft 20 take off (fly away) from the landing pad 130 by turning off the power supply to the first electromagnet device 131 or the second electromagnet device 211 and not generating a magnetic force between the miniature aircraft 20 and the landing pad 130.

[0033] Furthermore, in this embodiment, each of the small aircraft 20 and the landing pad 130 (at least one of the small aircraft 20 and the landing pad 130) is capable of automatically controlling the magnetic force based on detection information from built-in sensors or disaster prevention signals.

[0034] In this way, in the event of a disaster or the like, the fixed state of the small aircraft 20 fixed to the landing pad 130 can be automatically released, and the small aircraft 20 can take off more quickly from the landing pad 130. Also, in the event of an earthquake or the like, the magnetic force of attraction between the small aircraft 20 and the landing pad 130 can be automatically controlled to be increased, making it possible to prevent the small aircraft 20 from falling off the landing pad 130.

[0035] In this embodiment, the landing pad 130 is equipped with a sensor unit 133 that detects the approach of the miniature aircraft 20 (see FIG. 3). This sensor unit 133 can be configured using, for example, an ultrasonic sensor or an infrared sensor.

[0036] In this manner, in this embodiment, the landing pad 130 is provided with a sensor unit 133 that detects the approach of the miniature flying object 20, so that magnetic force is generated from the landing surface 130a only when the sensor unit 133 detects the approach of the miniature flying object 20. This makes it possible to prevent magnetic force from being needlessly generated from the landing surface 130a when the miniature flying object 20 is not present on the landing pad 130.

[0037] Furthermore, in this embodiment, the miniature aircraft 20 is equipped with a malfunction information detection means 213 that detects malfunction information of the lighting device 10, and a control unit 212 that controls the movement of the lighting device 10 detected by the malfunction information detection means 213 to the landing pad 130 (see Figure 3).

[0038] This makes it possible to automatically move the miniature aircraft 20 to the landing pad 130 of the lighting device 10 where the malfunction has occurred.

[0039] In addition, in this embodiment, the miniature aircraft 20 is equipped with a lighting unit 215, and the lighting unit 215 of the miniature aircraft 20 can illuminate the surroundings in place of the lighting fixture 120 that is turned off due to a power outage or the like (see Figures 2 and 3).

[0040] With such a lighting system 1, for example, as shown in FIG. 2, it becomes possible to illuminate the surroundings with the lighting unit 215 of the miniature aircraft 20 in place of a lighting fixture 120 that has become unlit due to a malfunction such as a breakdown.

[0041] Furthermore, in this embodiment, as described above, the miniature aircraft 20 is equipped with a malfunction information detection means 213 that detects malfunction information of the lighting fixture 120, and a control unit 212 that controls the movement of the lighting device 10 detected by the malfunction information detection means 213 to the landing pad 130.

[0042] Therefore, it is possible to automatically move the miniature aircraft 20 to the landing pad 130 of the lighting device 10 that has the malfunctioning luminaire 120.

[0043] In addition, Figure 2 shows an example in which the small aircraft 20 is kept waiting at the base 40, and when malfunction information is detected in the lighting fixture 120 (lighting device 10), the small aircraft 20 is launched from the base 40 and moved to the landing pad 130 above the lighting fixture 120 where the malfunction has occurred.

[0044] However, there is no need to launch the small aircraft 20 waiting at the base 40. For example, as shown in FIG. 4, it is also possible to move the small aircraft 20 fixed to the landing pad 130 of the lighting device 10 closest to the lamp 120 where the malfunction has occurred.

[0045] In addition, the miniature aircraft 20 may be flown periodically, and when a malfunctioning luminaire 120 is discovered, the miniature aircraft 20 may be directed to the landing pad 130 of the lighting device 10 that has the malfunctioning luminaire 120.

[0046] In addition, FIG. 4 also shows an example in which the miniature aircraft 20 and the landing pad 130 are each capable of automatically controlling their magnetic forces, but as shown in FIG. 5, the magnetic forces may also be manually controlled.

[0047] In other words, it is also possible for the operator U to manually control the magnetic force by operating the controller 30 remotely or visually.

[0048] The lighting system 1 may also be configured as shown in FIG.

[0049] In the lighting system 1 shown in FIG. 6, the miniature aircraft 20 and the landing pad 130 are equipped with non-contact power supply functions 134, 214, but the miniature aircraft 20 is not equipped with a lighting unit 215.

[0050] With such a lighting system 1, for example, with the miniature aircraft 20 fixed to the landing pad 130, power can be supplied to the miniature aircraft 20 from the landing pad 130, thereby charging the miniature aircraft 20. In this way, with the lighting system 1 shown in Fig. 6, the landing pad 130 can be used as a rest point for fixing and charging the miniature aircraft 20.

[0051] In addition, with the miniature aircraft 20 fixed to the landing pad 130, it is also possible to supply power from the miniature aircraft 20 to the landing pad 130, thereby supplying power to a lighting fixture 120 that is off due to a power outage or the like, thereby turning on the lighting fixture 120.

[0052] The lighting system 1 may also be configured as shown in FIG.

[0053] The lighting system 1 shown in FIG. 7 is obtained by adding contactless power supply functions 134, 214 to the lighting system 1 shown in the above embodiment.

[0054] With such a lighting system 1, the lighting unit 215 of the miniature aircraft 20 can illuminate the surroundings while the miniature aircraft 20 is being charged, making it possible for the lighting unit 215 to illuminate the surroundings for a long period of time.

[0055] The lighting system 1 may also be configured as shown in FIG.

[0056] The lighting system 1 shown in FIG. 8 is provided with a first electromagnetic device 131 and a second electromagnetic device 211 for fixing the miniature aircraft 20 to the landing pad 130, but is not provided with a lighting unit 215 or contactless power supply functions 134, 214.

[0057] In such a lighting system 1, the miniature aircraft 20 can be secured to the landing pad 130 in order to transport and replace parts such as light modules.

[0058] [Actions and Effects] The following describes the lighting systems shown in the above-described embodiments and their modified examples, as well as the characteristic configurations of the lighting devices used in the lighting systems, and the effects obtained thereby.

[0059] (1) The lighting system 1 shown in the above embodiment and its modified examples comprises a lighting device 10 having a small air vehicle (unmanned air vehicle) 20, a lighting fixture 120 capable of emitting light, and a landing pad 130 on which the unmanned air vehicle 20 lands.

[0060] The landing pad 130 has a landing surface 130a on which the miniature aircraft 20 lands. The landing pad 130 is provided with a first electromagnetic device 131 capable of generating a magnetic force from the landing surface 130a. The miniature aircraft 20 is provided with a second electromagnetic device 211 capable of generating a magnetic force.

[0061] Then, by generating a magnetic force that attracts each other in the first electromagnet device 131 and the second electromagnet device 211, the miniature aircraft 20 is fixed to the landing surface 130a.

[0062] In this way, by generating a mutually attractive magnetic force between the small aircraft 20 and the landing pad 130, the small aircraft 20 is fixed to the landing surface 130a, making it easier to fix the small aircraft 20 to the landing pad 130.

[0063] Furthermore, since electromagnetic devices are incorporated into both the miniature aircraft 20 and the landing pad 130, the miniature aircraft 20 can be more firmly fixed to the landing pad 130.

[0064] Therefore, with the lighting system 1 shown in the above embodiment and its modified example, it becomes possible to fix the miniature aircraft 20 to the landing pad 130 more easily and firmly.

[0065] Furthermore, if the miniature aircraft 20 is fixed to the landing pad 130 using magnetic forces generated by the miniature aircraft 20 and the landing pad 130, it becomes unnecessary to provide the landing pad 130 with a protrusion for hooking the miniature aircraft 20 or to provide a housing device for surrounding the miniature aircraft 20. However, if the landing pad 130 is provided with a protrusion for hooking the miniature aircraft 20 or a housing device for surrounding the miniature aircraft 20 in order to fix the miniature aircraft 20 to the landing pad 130, the shape and size of the miniature aircraft that can be fixed would be restricted.

[0066] However, in the lighting system 1 shown in the above embodiment and its modified example, as described above, it is not necessary to provide the landing pad 130 with a protrusion for hooking the miniature aircraft 20 or to provide a housing device for enclosing the miniature aircraft 20. Therefore, it becomes possible to fix various types of miniature aircraft 20 to the landing pad 130.

[0067] Another advantage is that by eliminating the need to provide a protrusion on the landing pad 130 for hooking the miniature aircraft 20 or a housing device for enclosing the miniature aircraft 20, the appearance of the landing pad 130 can be simplified.

[0068] (2) In addition, at least one of the miniature aircraft 20 and the landing pad 130 may have a function for controlling magnetic force.

[0069] In this way, it is possible to control the attractive magnetic force generated between the first electromagnet device 131 and the second electromagnet device 211 so that it is smaller than the lift of the miniature aircraft 20. For example, by turning off the power supply to the first electromagnet device 131 or the second electromagnet device 211, it is possible to prevent the attractive magnetic force from being generated between the first electromagnet device 131 and the second electromagnet device 211. As a result, it is possible to make the miniature aircraft 20 capable of taking off from the landing pad 130.

[0070] (3) Additionally, each of the miniature aircraft 20 and the landing pad 130 may have the function of controlling magnetic force.

[0071] In this way, it becomes possible to control the first electromagnet device 131 and the second electromagnet device 211 so that their magnetic properties repel each other. As a result, the mutually repulsive magnetic forces assist the miniature aircraft 20 in taking off from the landing pad 130, making it easier for the miniature aircraft 20 to take off from the landing pad 130.

[0072] (4) The landing pad 130 may also be equipped with a sensor unit 133 that detects the approach of the miniature aircraft 20.

[0073] In this way, magnetic force can be generated from the landing surface 130a only when the sensor unit 133 detects the approach of the miniature flying object 20. As a result, it is possible to prevent magnetic force from being generated unnecessarily from the landing surface 130a when the miniature flying object 20 is not present on the landing pad 130.

[0074] (5) The miniature aircraft 20 and the landing pad 130 may also be equipped with non-contact power supply functions 134, 214.

[0075] In this way, while the miniature aircraft 20 is fixed to the landing pad 130, power can be supplied from the landing pad 130 to the miniature aircraft 20, thereby charging the miniature aircraft 20. Also, while the miniature aircraft 20 is fixed to the landing pad 130, power can be supplied from the miniature aircraft 20 to the landing pad 130, thereby supplying power to the lighting fixture 120 that is off due to a power outage or the like, thereby turning on the lighting fixture 120.

[0076] (6) The small aircraft 20 may also be equipped with a malfunction information detection means 213 that detects malfunction information of the lighting device 10, and a control unit 212 that controls the movement of the lighting device 10 detected by the malfunction information detection means 213 to the landing pad 130.

[0077] In this way, it becomes possible to automatically move the miniature aircraft 20 to the landing pad 130 of the lighting device 10 where the malfunction has occurred.

[0078] (7) The miniature aircraft 20 may also be equipped with a lighting unit 215.

[0079] In this way, it becomes possible to illuminate the surroundings using the lighting unit 215 of the miniature aircraft 20 in place of the lighting fixture 120 that is not lit due to a power outage or the like.

[0080] (8) Furthermore, the lighting device 10 shown in the above embodiment and its modified example is a lighting device used in the lighting system 1 described above.

[0081] In this way, it is possible to obtain the lighting device 10 used in the lighting system 1 that can more easily and firmly fix the miniature aircraft 20 to the landing pad 130.

[0082] [others] The lighting system according to the present disclosure and the lighting device used in the lighting system have been described above. However, the present disclosure is not limited to the above description, and it will be obvious to those skilled in the art that various modifications and improvements are possible.

[0083] For example, it is possible to provide a lighting system and a lighting device used in the lighting system by appropriately combining the configurations shown in the above-described embodiment and the modified examples thereof.

[0084] In the above embodiment and its modified example, the lighting device 10 is exemplified as having one lighting fixture 120 attached to the tip of the pole 110 extending in the vertical direction, but it is also possible to have a lighting device in which the lighting fixture 120 is attached to an arm section bent horizontally at the tip of a pole. It is also possible to have a lighting device in which multiple lighting fixtures 120 are attached to the pole 110.

[0085] In addition, in the above embodiment and its modified examples, an example was given of a lighting device 10 in which the luminaire 120 is installed in a position that is out of reach of people, but it is also possible to apply the lighting system 1 of the present disclosure to a lighting device in which the luminaire is installed in a position that is within reach of people.

[0086] In the above embodiment and its modified example, the lighting device 10 in which the lighting fixture 120 is installed on the dedicated pole 110 has been exemplified, but the lighting fixture 120 can be installed in various locations as long as the location is capable of mounting an electromagnetic device. For example, the lighting fixture can be installed on a member that can also function as a lighting device, such as a utility pole or a roof.

[0087] In addition, the landing platform 130 does not need to be disposed so as to be in contact with the lighting fixture 120, and it is also possible to dispose the landing platform 130 apart from the lighting fixture 120. For example, it is also possible to install the lighting fixture 120 and the landing platform 130 on the pole 110.

[0088] In addition, the lighting system of the present disclosure can be applied to garden lights that illuminate plants in a garden, and the like, and can also be applied to lighting devices installed in museums and other buildings, and indoor lighting installed in homes.

[0089] In the above embodiment and its modified example, the landing surface 130a is provided on the upper surface of the landing platform 130, but the lower surface or side surface of the landing platform may be used as the landing surface. The shape of the landing platform 130 is not limited to a rectangular plate shape and may be various other shapes.

[0090] In addition, the specifications of the unmanned aerial vehicle, lighting fixtures, and other details (shape, size, layout, etc.) can be changed as appropriate. [Explanation of symbols]
