Description

[Technical Field]

[0001] The present invention relates to a lighting device and a method of operating the same. [Background technology]

[0002] Lighting devices shaped like soap bubbles have been known for some time (for example, Patent Document 1). The lighting device described in Patent Document 1 has a globe part that receives light from an LED and is made of transparent glass in the shape of a soap bubble, and is said to be a glass representation of a fleeting shape created by nature.

[0003] Furthermore, Patent Document 2 discloses a lighting device in which a plurality of decorative LED strips are arranged inside a refractive crystal cover and the LED strips are mechanically swung. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Design Registration No. 1454514 [Patent Document 2] Chinese Utility Model No. 207796637 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the movement, rotation direction, and brightness of real soap bubbles change from moment to moment. However, the lighting device in Patent Document 1 has LEDs placed inside a glass globe and is designed to be used stationary, so its movement and brightness hardly change. In other words, the lighting device in Patent Document 1 only imitates the momentary shape of a soap bubble and cannot reproduce the natural behavior of a soap bubble.

[0006] Furthermore, the lighting device in Patent Document 2 includes a mechanism for oscillating the decorative LED strip inside the refractive crystal cover, but the refractive crystal cover itself does not rotate or oscillate. Furthermore, this lighting device is intended to be placed on a table or floor. Therefore, the lighting device in Patent Document 2 cannot reproduce the natural behavior of soap bubbles.

[0007] SUMMARY OF THE INVENTION Therefore, a main object of the present invention is to provide an illumination device that can reproduce the behavior of soap bubbles more naturally. [Means for solving the problem]

[0008] After extensive research into how to achieve the above object, the inventor of the present invention came up with a configuration in which a light-emitting element and a rotating element are provided inside an exterior element suspended from a wire element, and the force generated when the rotor of the rotating element is rotated is indirectly transmitted to the exterior element and the wire element. This configuration allows the lighting device to rotate naturally, like a soap bubble, by controlling the rotation and stopping of the rotor of the rotating element. Based on the above findings, the inventor then came up with the idea of solving the problems of the prior art and completed the present invention. Specifically, the present invention has the following configuration.

[0009] A first aspect of the present invention relates to a hanging-type lighting device 100. The lighting device 100 according to the present invention includes a wire member 10, an exterior member 20, a light-emitting member 30, a rotating member 40, and a connecting structure 50. The wire member 10 is used to suspend the lighting device 100, for example, from a ceiling. The exterior member 20 is transparent or translucent and has an internal space. The exterior surface of the exterior member 20 is preferably a half-mirror. The exterior member 20 may be a hard case made of plastic or glass, or a soft case made of plastic film or the like. The light-emitting member 30 is provided within the exterior member 20. The light-emitting member 30 may be a cable-like member that is freely provided within the exterior member 20. The term "freely provided" means that the entire cable-like light-emitting member 30 is not fixed to another structure, but rather that at least a portion of the light-emitting member 30 is free from the other structure and moves within the exterior member 20 due to some action. The rotating member 40 includes a rotor and a stator provided within the exterior member 20. For example, the rotor is the rotor of a motor, and the stator is the stator of a motor. The connecting structure 50 connects the wire member 10, the exterior member 20, and the stator of the rotating member 40 so that a force applied to any one of the members is transmitted to the other members. For example, by rotating the rotor, the stator also gradually tends to rotate in the same direction, and the rotational force thus applied to the stator is transmitted to the wire member 10 and the exterior member 20 via the connecting structure 50. The rotation and stopping of the rotor of the rotating member 40 may be controlled independently by the lighting device 100, or may be controlled by a higher-level control device connected to the lighting device 100.

[0010] As described above, providing the rotating member 40 inside the exterior member 20 of the lighting device 100 allows the lighting device 100 to rotate independently. For example, with this lighting device 100, there is no need to place a powerful external fan to rotate the exterior member 20. Furthermore, if an external fan were to be used to rotate the lighting device 100, it would be difficult to send air to all of the lighting devices 100, especially in a large venue where the lighting devices 100 are installed. While the lighting device 100 could be rotated by directly twisting the hanging cable, this would place a heavy load on the cable, potentially damaging it. The present invention solves these problems and more naturally reproduces the behavior of soap bubbles.

[0011] The lighting device 100 according to the present invention is preferably configured such that by rotating the rotor of the rotating member 40, the exterior member 20 rotates in one direction and the wire member 10 is twisted, and then by stopping the rotor of the rotating member 40, the twist in the wire member 10 is restored and the exterior member 20 rotates in the opposite direction. By controlling the rotation (on) and stop (off) of the rotating member 40 in this manner, the lighting device 100 can be rotated gently in both the clockwise and counterclockwise directions. For this reason, it is preferable that the rotation and stop of the rotor of the rotating member 40 be performed alternately.

[0012] In the lighting device 100 according to the present invention, the rotating member 40 may be a fan that is driven to rotate by a motor. By controlling the rotation and stopping of the fan, the lighting device 100 can be rotated gently in the clockwise and counterclockwise directions, as described above. Furthermore, the rotation of the fan generates an airflow within the exterior member 20, which can be expected to have the effect of flickering the light-emitting members 30 that are provided freely. Note that the fan is provided within the exterior member 20 primarily for the purpose of rotating the lighting device 100, and it is not intended that the exterior member 20 will be moved by the airflow generated by the fan. Therefore, there is no need to provide vents in the container member 51 that stores the fan, the pressing member 52 that holds the fan, or the like.

[0013] In the lighting device 100 according to the present invention, the rotating member 40 may be a flywheel that is driven to rotate by a motor. By controlling the rotation and stopping of the flywheel, the lighting device 100 can be rotated gently in the clockwise and counterclockwise directions as described above.

[0014] In the lighting device 100 according to the present invention, the rotating member 40 may include a frame 43 to which a stator is attached. The connecting structure 50 may include a container member 51, a presser member 52, and a lid member 53. The container member 51 is fixed to the lower part of the frame 43 of the rotating member 40 and is used to house the rotating member 40. The presser member 52 is fixed to the upper part of the frame 43 of the rotating member 40 and is also used to house the container member 51. The lid member 53 is fixed to the exterior member 20 and is used to hold the container member 51 within the exterior member 20. In this case, the wire member 10 may be fixed to the presser member 52. With this connecting structure 50, the force acting on the stator due to the rotation of the rotor of the rotating member 40 can be efficiently transmitted to the exterior member 20 and the wire member 10.

[0015] A second aspect of the present invention relates to a method for operating a pendant lighting device 100. This lighting device 100 relates to the first aspect described above. Specifically, the lighting device 100 includes a wire member 10, a transparent or translucent exterior member 20 having an internal space, a light-emitting member 30 provided within the exterior member 20, a rotating member 40 including a rotor and a stator provided within the exterior member 20, and a connecting structure 50 connecting the wire member 10, the exterior member 20, and the stator of the rotating member 40 so that a force applied to any one of the members is transmitted to the other members. In this case, the operating method of the lighting device 100 first rotates the rotor of the rotating member 40 to rotate the exterior member 20 in one direction and generate a twist in the wire member 10 (first step). Then, the operating method further includes stopping the rotor of the rotating member 40 to restore the twist in the wire member 10 and rotate the exterior member 20 in the opposite direction (second step). [Effects of the Invention]

[0016] The lighting device according to the present invention can reproduce the behavior of soap bubbles more naturally. [Brief explanation of the drawings]

[0018] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below, and includes appropriate modifications of the embodiments described below within the scope obvious to those skilled in the art.

[0019] FIG. 1 shows a lighting device 100 according to one embodiment of the present invention. As shown in FIG. 1, the lighting device 100 includes a wire member 10, which can be used to hang the lighting device 100 from a ceiling or the like. The lighting device 100 also includes a spherical, transparent or translucent exterior member 20. A light-emitting member 30, such as an LED cable, and various other components are housed within the interior space of the exterior member 20. In this embodiment, a plastic or glass cover having a certain degree of hardness is used as the exterior member 20. The surface of the exterior member 20 is semitransparently mirrored, allowing external objects to be reflected on the surface. In the example shown in FIG. 1, two lighting devices 100 are placed close to each other, and therefore, the other lighting device 100 is reflected on the surface of the exterior member 20 of one of the lighting devices 100. The half mirror preferably has a light reflectance of less than 80% and a light transmittance of 10 to 50%, and is preferably configured to mainly reflect light from outside the exterior member 20 and transmit light from inside the exterior member 20. The size of the exterior member 20 is not particularly limited as long as it can accommodate the various devices described below. For example, the diameter of the exterior member 20 is preferably 150 to 500 mm. Although not shown, the interior of the exterior member 20 may also accommodate a translucent iridescent film called an aurora film or chameleon film, which changes color depending on the viewing angle and the way light hits it. This allows the lighting device 100 to shine like a soap bubble when the light-emitting member 30 inside the exterior member 20 is turned on.

[0020] 2 to 4 show exploded perspective views of various components constituting the lighting device 100 according to this embodiment. As shown in these figures, the lighting device 100 includes, in addition to the wire member 10 and the exterior member 20, a light-emitting member 30, a rotating member 40, a connecting structure 50, a control member 60, a screw 70, and a power supply cable 80. The connecting structure 50 here is a structure that mainly connects the wire member 10, the exterior member 20, and the stator of the rotating member 40 so that a force applied to any one of the members is transmitted to the other members. In other words, when the stator of the rotating member 40 is moved, the exterior member 20 and the wire member 10 move in conjunction with each other, and similarly, when the wire member 10 is moved, the exterior member 20 and the stator of the rotating member 40 move in conjunction with each other. This relationship is realized by the connecting structure 50. Specifically, as shown in FIGS. 2 to 4, the connecting structure 50 mainly includes a container member 51, a presser member 52, and a cover member 53.

[0021] First, as shown in FIG. 2 , the container member 51 is a cup-shaped member capable of accommodating the main components, such as the rotating member 40, the pressing member 52, and the control member 60. The container member 51 has a storage section 51a deep enough to accommodate these components, and a flange portion 51b that protrudes outward from the upper periphery of the storage section 51a. The storage section 51a is formed in the shape of a rectangular cylinder with a bottom and an opening at the top, and has an internal storage space with a rectangular cross section. The rotating member 40 and the pressing member 52, which also have a rectangular cross section, are accommodated in this storage space. At this time, the rotating member 40 and the pressing member 52 are inscribed in the storage section 51a of the container member 51. Therefore, the rotating member 40 and the pressing member 52 do not shift or move within the container member 51. In this way, the container member 51 functions as part of the connecting structure 50. Although not shown in the figures, no ventilation holes or the like are formed in the bottom surface of the accommodation section 51a of the container member 51 to allow passage of the wind generated by the rotation of the rotating member 40 (fan). However, holes 51c are formed in the four side walls at the top of the accommodation section 51a of the container member 51, specifically near the boundary between the accommodation section 51a and the flange portion 51b. As shown in Fig. 4, these holes 51c are holes for passing the cable-shaped light-emitting member 30 through.

[0022] Furthermore, when the lighting device 100 is viewed from the outside, the container member 51 is preferably mirrored on its outer surface so that it is less noticeable through the translucent exterior member 20. As mentioned above, the container member 51 does not need any ventilation holes, so the mirrored area can be increased. This makes it possible to make the container member 51 less noticeable when the lighting device 100 is viewed from the outside.

[0023] The rotating member 40 is a member for generating a rotational force that rotates the entire lighting device 100 in the horizontal direction. The rotating member 40 may be a member having a rotor with a rotation axis aligned in the vertical direction and a stator that generates a rotating magnetic field to rotate the rotor in the horizontal direction. In this embodiment, a fan is used as the rotating member 40. Note that either a DC axial fan or an AC axial fan may be used as the rotating member 40. The fan includes a motor unit 41 including a rotor and a stator, blades 42 fixed to the rotation shaft (output shaft) of the motor unit 41, and a frame 43 attached to the stator of the motor unit 41. The fan blades 42 are not fixed to any other component within the lighting device 100, and therefore rotate freely when power is supplied to the motor unit 41. When the blades 42 rotate, a rotational force that rotates the motor unit 41 and the frame 43 to which it is fixed is applied in the same direction as the blades 42. In this embodiment, the rotational force generated secondarily in association with the rotation of the blade portion 42 is used as a force for rotating the entire lighting device 100.

[0024] In this embodiment, a fan is used as the rotating member 40, but the airflow generated by the fan is not particularly necessary. Therefore, the container member 51 that houses the rotating member 40 (fan) and the pressing member 52 that presses down on the rotating member 40 from above do not need ventilation holes that serve as a path for the airflow.

[0025] Furthermore, since an airflow is not required in this embodiment as described above, it is possible to use, instead of a fan, a rotating member 40 such as a flywheel that does not generate an airflow. While the configuration of a flywheel is not illustrated, the flywheel primarily comprises a motor unit including a rotor and a stator, a disk unit fixed to the rotating shaft (output shaft) of the motor unit, and a frame attached to the stator of the motor unit. The disk unit of the flywheel is not fixed to any other component within the lighting device 100, and therefore rotates freely when power is supplied to the motor unit. When the disk unit rotates, a rotational force that rotates in the same direction as the disk unit is applied to the motor unit and the frame to which it is fixed. In this way, the rotational force generated secondarily as a result of the rotation of the disk unit of the flywheel can be used to rotate the entire lighting device 100.

[0026] The holding member 52 is disposed above the rotating member 40 and serves to hold the rotating member 40 within the container member 51. In other words, the rotating member 40 is sandwiched between the bottom surface of the container member 51 and the holding member 52 within the container member 51. The holding member 52 is primarily a flat, plate-shaped member, and a wire fixing portion 52a for fixing the lower end of the wire member 10 is provided on the upper surface of the center of the plate-shaped portion. The wire fixing portion 52a is configured so that when the holding member 52 rotates horizontally, the wire member 10 can be rotated in the same direction, thereby twisting the wire member 10. The structure of the wire fixing portion 52a is not particularly limited. For example, as shown in FIG. 2, a small hole through which the wire member 10 can be inserted is formed in the center of a semicircular arch shape, and the small hole is sized so that a fastener attached to the lower end of the wire member 10 will not pass through the small hole. Furthermore, the fastener at the lower end of the wire member 10 is shaped to contact the arch-shaped portion of the wire fixing portion 52a. Therefore, when the pressing member 52 rotates, the rotational force is also transmitted to the wire member 10 via the fastener. Furthermore, a plurality of screw holes 52b into which screws 70, which will be described later, are fitted is provided on the upper surface of the pressing member 52. Meanwhile, protrusions 52c are formed on the four corners of the upper surface of the pressing member 52. These protrusions 52c are fitted into recesses 44 provided on the four corners of the frame 43 of the rotating member 40 (fan). In this way, when the pressing member 52 and the frame 43 of the rotating member 40 are fitted together and then housed in the container member 51, both members are fixed in the container member 51.

[0027] As shown in FIG. 3 , a control member 60 is disposed above the holding member 52. The control member 60 is a member for controlling the electronic devices included in the lighting device 100, specifically the light-emitting members 30 (LED cables) and the rotating member 40 (fan). The functional configuration of the control member 60 will be described later with reference to FIG. 5 . First, the structure of the control member 60 will be described. The control member 60 has a substantially rectangular substrate. A wire-through hole 60a is provided in the center of the substrate for inserting the wire member 10, and screw-through holes 60b are provided at each of the four corners of the substrate. With the wire member 10 threaded through the control member 60, the control member 60 is disposed above the holding member 52, and the control member 60 is also accommodated within the accommodation space of the container member 51. Then, screws 70 are passed through the screw-through holes 60b of the control member 60, and the screws 70 are tightened into the screw holes 52b of the holding member 52. This fixes the control member 60 onto the holding member 52.

[0028] As shown in FIG. 4 , a light-emitting member 30 is attached to each output terminal of the control member 60. In this embodiment, four light-emitting members 30 can be electrically connected to the control member 60. Preferably, an LED cable is used as the light-emitting member 30. The LED cable is a cable-shaped member in which a plurality of LED light-emitting elements 31 are connected. One end of each LED cable is connected to the control member 60 and receives control signals and power from the control member 60. The other end of each LED cable is free and not fixed to any location. Therefore, as shown in FIG. 4 , each LED cable hangs down freely from the control member 60. Each LED cable extends outside the storage space of the container member 51 through a hole 51c formed in the container member 51. Each LED cable is then housed entirely within the exterior member 20.

[0029] 4, a power supply cable 80 is connected to each input terminal of the control member 60. The control member 60 receives power via this power supply cable 80 to be supplied to the electronic devices on the control member 60, the light emitting members 30 (LED cables), and the rotating members 40 (fans). The power supplied to the light emitting members 30 (LED cables) and the rotating members 40 (fans) is controlled by this control member 60. When controlling multiple lighting devices 100 to perform a light-based performance, a higher-level control device (not shown) is provided to control the multiple lighting devices 100, and this control device transmits control signals for the light emitting members 30 and the rotating members 40 to the control members 60 of each lighting device 100 via the power supply cable 80. The control members 60 of each lighting device 100 distribute the control signals received from the higher-level control device to the light emitting members 30 and the rotating members 40. In this case, it is the higher-level control device that actually controls the light emitting members 30 and the rotating members 40, and the control member 60 functions as a terminal block for distributing the control signals from the higher-level control device.

[0030] As shown in FIG. 4 , a circular lid member 53 is attached to the top of the container member 51. The lid member 53 is fixed by butting against a flange portion 51b of the container member 51. There are no particular limitations on the method for fixing the lid member 53 to the container member 51. For example, the lid member 53 may be mechanically coupled to the container member 51 by providing a mating claw on one of them and a receiving portion for the mating claw on the other. Alternatively, the lid member 53 and the container member 51 may be fastened to each other with a fastener such as a pin. The lid member 53 has a thread groove 53a formed on the inner surface of the side wall, and is configured so that a screw thread 22 formed around the opening 21 at the top of the exterior member 20 can be fitted into this thread groove 53a. With the lid member 53 and the container member 51 coupled together, the lid member 53 and the exterior member 20 are fixed to each other by fitting the screw thread 22 of the exterior member 20 into the thread groove 53a of the lid member 53. Furthermore, a wire-through hole 53b for inserting the wire member 10 is provided in the center of the top plate of the cover member 53. A cable-through hole 53c for inserting the power supply cable 80 is also provided in the top plate of the cover member 53. In this manner, the wire member 10 and the power supply cable 80 are drawn out to the outside through the cover member 53. In this manner, the lighting device 100 is in the state shown in FIG. 1 by storing various members inside the exterior member 20 and closing the opening 21 of the exterior member 20 with the cover member 53.

[0031] Next, the functional configuration of the control member 60 will be specifically described with reference to FIG. 5. In this embodiment, the control member 60 is configured by a printed circuit board on which electronic components for controlling the light-emitting members 30 (LED cables) and the rotating members 40 (fans) are assembled. FIG. 5 shows an example of functional elements included in the control member 60. In the example shown in FIG. 5, the control member 60 includes a processor 61, a memory 62, a communication device 63, a drive control circuit 64, and a light-emitting control circuit 65. Examples of the processor 61 include a known CPU or other control circuit. The processor 61 performs predetermined arithmetic processing in accordance with programs and data stored in the memory 62, and executes various control processes while writing the results of the calculations to a workspace in the memory 62. The memory 62 is configured, for example, by a volatile memory such as a RAM (Random Access Memory) or a non-volatile memory such as a flash memory, and is used for the arithmetic processing by the processor 61. In this embodiment, the processor 61 reads out a program stored in the memory 62 and performs processing to drive the rotating members 40 and cause each light-emitting member 30 to emit light in accordance with the program.

[0032] The communicator 63 is a communication module for wireless or wired communication with an external control device. In the wireless system, the communicator 63 may be configured to communicate wirelessly using a known wireless communication standard such as Wi-Fi (registered trademark), Bluetooth (registered trademark), or NFC, another proprietary standard, a frequency such as the sub-GHz band, or P2MP or Mesh communication other than WLAN. On the other hand, in the wired system, the communicator 63 can communicate with an external control device via the power supply cable 80, simultaneously with or separately from power supply. For example, the lighting device 100 communicates with an external control device (not shown) via the communicator 63. In this case, the lighting device 100 can control the driving state of the rotating member 40 and the light-emitting state of the light-emitting member 30 based on instructions and commands received from the external control device. The lighting device 100 can also communicate with other lighting devices 100 (not shown) via the communicator 63, either wired or wirelessly. In this case, information may be shared among the plurality of lighting devices 100 to control the driving state of the rotating member 40 and the light emitting state of the light emitting member 30. For example, the light emitting color and blinking pattern of the light emitting member 30 may be linked among the plurality of lighting devices 100. Furthermore, the driving pattern of the rotating member 40 may be linked among the plurality of lighting devices 100.

[0033] The drive control circuit 64 is a circuit that supplies power from the power supply cable 80 to the rotating member 40 so that the rotating member 40 is driven under predetermined drive conditions (rotation speed, rotation pattern, rotation direction, etc.) based on a control command from the processor 61. The light emission control circuit 65 is a circuit that supplies power from the power supply cable 80 to the light emitting member 30 so that the light emitting element 31 of the light emitting member 30 emits light under predetermined light emission conditions (emission color, brightness, light emission pattern, etc.) based on a control command from the processor 61. The light emission control circuit 65 is also capable of independently controlling each of the multiple light emitting members 30.

[0034] In the embodiment shown in FIG. 5 , a processor 61 is provided in the control member 60 of the lighting device 100, and the lighting device 100 autonomously controls its own light-emitting members 30 and rotating members 40. However, the present invention is not limited to this embodiment. Specifically, a host control device (computer) is provided to externally control the lighting device 100, and control signals for the light-emitting members 30 and rotating members 40 are transmitted from the control device to the lighting device 100 via a power supply cable 80. The control member 60 of each lighting device 100 distributes the control signals received from the host control device to the light-emitting members 30 and rotating members 40. In this case, it is the host control device that actually controls the light-emitting members 30 and rotating members 40, and the control member 60 functions as a terminal block for distributing the control signals from the host control device. In this manner, it becomes possible for a host control device to simultaneously control multiple lighting devices 100.

[0035] In the lighting device 100 of this embodiment, the light-emitting elements 31 of the light-emitting member 30 are turned on and the rotating member 40 is driven to slowly rotate the entire lighting device 100, thereby reproducing the behavior of a real soap bubble, which changes in brightness from moment to moment and rotates naturally. For example, the light-emitting control circuit 65 may not only constantly light the light-emitting elements 31 of the light-emitting member 30, but also control them to repeatedly blink at a predetermined or random interval. The light-emitting control circuit 65 may also control the light-emitting color of the light-emitting elements 31 of the light-emitting member 30. The light-emitting control circuit 65 may also control these light-emitting conditions for each light-emitting member 30, or for each light-emitting element 31 constituting the light-emitting member 30. The drive control circuit 64 may not only constantly drive the rotating member 40, but may also control it to switch on / off at a predetermined or random interval, or to repeatedly increase or decrease the number of rotations at a predetermined or random interval. In this way, by blinking the light emitting member 30 and adjusting the on / off and rotation speed of the rotating member 40, the lighting device 100 can reproduce the behavior of a real soap bubble.

[0036] Next, with reference to Fig. 6, a mechanism for rotating the entire lighting device 100 will be described. First, as shown in Fig. 6(a), the rotor of the rotating member 40 housed in the container member 51 of the lighting device 100 is rotated. By rotating the rotor, a rotational force is also generated in the stator of the rotating member 40. The rotational force applied to the stator of the rotating member 40 is transmitted to the exterior member 20 and the wire member 10 by the connecting structure 50 including the container member 51, and the exterior member 20 and the wire member 10 also begin to rotate slowly in the same direction as the rotor of the rotating member 40. When the wire member 10 rotates, a twist is generated in the wire member 10, and the rotational force applied to the wire member 10 is accumulated in the wire member 10 as this twist.

[0037] Next, as shown in Fig. 6(b), the rotor of the rotating member 40 is stopped. Even when the rotor is stopped, the outer covering member 20 and the wire member 10 do not stop immediately, but continue to rotate in the same direction due to inertia, but the rotation speed gradually slows down, and finally the rotation of the outer covering member 20 etc. stops.

[0038] The rotor of the rotating member 40 remains stopped thereafter. Then, as shown in FIG. 6( c), the force of restoring the twist accumulated in the wire member 10 causes the outer casing 20 and the wire member 10 to start rotating in the opposite direction. If the rotation in the opposite direction continues, the twist in the wire member 10 is released, and then the wire member 10 twists in the opposite direction again, untwists, and then twists in the opposite direction again, gradually stopping the rotation of the wire member 10 and the outer casing 20. Then, as shown in FIG. 6( a), by rotating the rotor of the rotating member 40 again, the wire member 10 and the outer casing 20 start rotating again in the same direction as the rotor. Note that the rotation of the rotor of the rotating member 40 may be resumed after the rotation of the wire member 10 and the outer casing 20 has completely stopped, or the rotation of the rotor of the rotating member 40 may be resumed before the rotation of the wire member 10 and the outer casing 20 has stopped.

[0039] In this way, by periodically turning the rotating member 40 ON and OFF, the entire lighting device 100 can be rotated gently in one direction and then the other. Furthermore, while the lighting device 100 is rotating, the light-emitting members 30, such as the LED cables inside the exterior member 20, also naturally sway. Furthermore, the light-emitting members 30 inside the lighting device 100 can be turned on or off. This makes the lighting device 100 (particularly the exterior member 20) appear to be shining like soap bubbles. In this way, the behavior of soap bubbles can be reproduced more naturally. Furthermore, as shown in FIG. 1, by arranging multiple lighting devices 100, each having a mirrored or half-mirror exterior member 20, side by side, the exterior member 20 of one lighting device 100 reflects the pattern of a soap bubble on the exterior member 20 of another adjacent lighting device 100. In this state, by gently rotating multiple adjacent lighting devices 100 as described above, the lighting devices 100 can be coordinated to create a beautiful effect.

[0040] In the above description of the present invention, the embodiments of the present invention have been described with reference to the drawings in order to express the contents of the present invention. However, the present invention is not limited to the above embodiments, and includes modifications and improvements that are obvious to those skilled in the art based on the matters described in the present specification.

[0041] For example, in this embodiment, power is supplied to the control member 60, the rotation member 40, and the light emitting members 30 via the power supply cable 80, but instead, a small battery can be mounted on the lighting device 100 itself, and power can be supplied from this battery to the control member 60, the rotation member 40, and the light emitting members 30. The battery may be a primary battery or a secondary battery. However, since repeatedly rechargeable batteries provide higher operational efficiency, it is preferable to use secondary batteries when a battery is mounted. [Explanation of symbols]
