More specifically, the present invention relates to a lighting device that stands up even when knocked down, and a lighting performance system and lighting performance method using the lighting device.

Conventionally, light emission control devices equipped with LEDs have been mounted inside multiple balls (balloons) containing gas, and the LEDs inside each ball have been synchronized. A method has been proposed to change the color of the emitted light (Patent Document 1). For example, in Patent Document 1, when a light emission control device inside a ball detects the movement of a ball, it changes the color of light emitted from an LED, and when a certain ball moves, the LEDs inside a plurality of other balls are turned on all at once. It is disclosed to change to

Balls equipped with such LEDs, for example, float freely above the heads of spectators in an event venue. change to Therefore, spectators can not only enjoy the lighting performance by the light emission of the ball, but also enjoy the pleasure of freely moving the ball. In recent years, interactive lighting effects using such luminous balls have gained popularity.

JP 2011-130979

By the way, a ball that emits light while floating is suitable for lighting effects indoors, but it is not suitable for outdoor use because it is difficult to control the floating direction. It is also conceivable to use a ball that emits light by fixing it to the ground or a wall.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a novel lighting device that replaces the luminous ball.

The inventors of the present invention, as a result of intensive studies on means for achieving the above object, have found that by mounting a light-emitting part such as an LED inside a hollow rocking body like a rising pedestal, it is possible to use it outdoors. The inventors have found that it is possible to provide a suitable novel lighting device. Based on the above findings, the inventors of the present invention realized that a more attractive lighting performance can be realized, and completed the present invention. Specifically, the present invention has the following configurations and steps.

A first aspect of the present invention relates to a lighting device. A lighting device of the present invention includes an oscillator and a light emission control device. The oscillating body has a bowl-shaped bottom surface, and a weight member is provided on the inner bottom surface side. Note that the bottom surface of the oscillator is the contact surface with the floor or the ground. Therefore, even if the rocking body falls down, it will stand up with the bottom side down, like an upright child. The light emission control device includes a light emitting section enclosed in the oscillator. Therefore, when the light emitting section emits light, the oscillator (transparent or translucent) is illuminated from inside. Although it is preferable that the entire light emission control device is contained within the oscillator, it is sufficient that at least the light emitting unit is provided inside the oscillator, and other equipment (such as a power supply) that constitutes the light emission control device is not included in the oscillator. may be provided outside the By providing a light-emitting portion inside such a swinging body, it is possible to provide a novel lighting device that swings when pushed by a spectator, for example. In addition, since the bottom surface of the oscillating body is basically in contact with the floor or the ground, the lighting device of the present invention can be suitably used for outdoor lighting effects.

In the illumination device of the present invention, it is preferable that the light emission control device further includes a wireless communication unit (wireless communication device). The wireless communication unit receives control information for the light emitting unit transmitted from both or one of the external control device and the other lighting device. In this case, the light emitting unit emits light according to control information received from an external control device or another lighting device. In other words, the lighting device may be controlled by an external control device (computer) as a parent device, or a plurality of lighting devices may be mutually controlled by a peer-to-peer method. Information may also be exchanged. In this way, by providing a wireless communication unit in the lighting device, the degree of freedom in lighting effects is greatly improved.

In the illumination device of the present invention, the light emission control device may further include a motion detection section and a light emission control section. The motion detector detects the motion of the oscillator. The light emission control section changes the light emission state of the light emitting section in accordance with the motion of the oscillator detected by the motion detection section. As a result, for example, when the spectator swings the swinging body, the light emission state changes, so that an interactive lighting effect can be performed.

In the illumination device of the present invention, the motion detector may include an acceleration sensor that measures acceleration of motion of the oscillator. In this case, it is preferable that the light emission control section changes the light emission state of the light emission section when the acceleration of the movement of the oscillator exceeds a certain threshold. As a result, when a strong impact is applied to the rocking body, such as when a spectator strongly pushes the rocking body, the light emitting state of the light emitting section changes. Also, it is possible to control so that the light emitting state does not change when the oscillator is slowly shaken by wind or the like.

In the illumination device of the present invention, the motion detector may include a tilt sensor that measures the tilt angle of the oscillator. In this case, the light emission control unit does not change the light emitting state of the light emitting unit when the tilting angle of the oscillator is within a certain angle range, even if the acceleration of the motion of the oscillator exceeds a certain threshold. (Cancel the change in the light emission state). For example, when the spectator strongly pushes the top of the rocking body, the rocking body may receive a first impact due to the audience's pushing motion, and then receive a second impact when it contacts the ground. In such a case, it is possible to control the light emission state to change when it receives the first impact from the audience, and not to change the light emission state when it receives the second impact due to contact with the ground.

In the illumination device of the present invention, the motion detector may include a tilt sensor that measures the tilt angle of the oscillator. In this case, the light emission control section may change the light emission state of the light emitting section according to the tilt angle of the oscillator. As a result, it is possible to provide lighting performance in which, for example, the luminescence state (luminescence color or luminescence intensity) of the light emitting unit gradually changes according to the rocking motion of the rocking body.

The light emission control device of the present invention may further include a wireless communication unit for transmitting motion information of the oscillator detected by the motion detection unit to both or one of an external control device and another lighting device. As a result, it is possible to change the light emitting state of the light-emitting portion in another oscillator according to the operation of a certain oscillator. For example, when a certain rocking body moves to change its light emitting state, it is possible to produce an effect in which the rocking bodies positioned around it also change their light emitting states in the same way.

A second aspect of the present invention relates to a lighting production system. A lighting performance system of the present invention includes one or more lighting devices (equipped with a wireless communication unit) and a control device that controls the light emitting state of the light emitting units of the lighting devices. The control device includes a wireless communication unit that transmits control information for controlling the light emission unit to the light emission control device. As a result, the control device (computer) can be used as a parent device, and one or a plurality of other lighting devices can be used as child devices, and the parent device can control the entire child device.

A third aspect of the present invention relates to a lighting production method. The lighting presentation method of the present invention is executed by one or a plurality of lighting devices (equipped with wireless communication units) and a control device that controls the light emitting state of the light emitting units of the lighting devices. The lighting presentation method of the present invention includes the step of transmitting control information for controlling the light emitting unit from the control device to the light emission control device. As a result, the light emission control device of the lighting device and the light emission section are caused to emit light according to the control information from the control device.

According to the present invention, it is possible to realize a novel lighting effect.

The storage unit 220 can be realized by nonvolatile memories such as HDD and SDD, and volatile memories such as RAM and DRAM. The wireless communication unit 230 is a communication interface for transmitting and receiving information between the control device 100 and other light emission control devices 200, and uses a known wireless communication such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). Communicate according to communication standards. The light emitting unit 240 is composed of a light emitting element such as an LED. For example, the light emitting unit 240 has one or a plurality of red LEDs, green LEDs, and blue LEDs, and is capable of emitting multi-gradation color light with various luminances. The motion detection unit 250 is composed of various sensors for detecting motion of the rocking body 2 . Examples of the motion detection unit 250 include an acceleration sensor for measuring acceleration, a tilt sensor (for example, a gyro sensor) for measuring tilt angle and angular velocity, or a vibration sensor for detecting vibration of an oscillating body. Or it can be used in combination. The radio signal transmitter 260 transmits a radio signal including its own identification information, and this radio signal is received by a plurality of radio signal receivers 300 installed in the venue.

It controls transmission via the transmission unit 260 . The sound control unit 213 controls the speaker based on the sound data stored in the storage unit 220 to output sounds such as sound effects and BGM.

Here, an example of processing for acquiring the position coordinates of the plurality of lighting devices 1 (light emission control devices 200) by the control device 100 will be described in detail. A plurality of radio signal receivers 300 are installed in an outdoor or indoor event venue, and each receiver 300 is assigned unique ID information (identification). Also, the radio signal transmission unit 260 of the light emission control device 200 constantly transmits a radio signal including unique identification information. Each radio signal receiver 300 receives the radio signal emitted by the light emission control device 200 . Note that since the wireless signal emitted by the light emission control device 200 is for short-range communication, only the wireless signal receiver 300 located near the light emission control device 200 (within the wireless signal reachable range) can transmit the wireless signal. will be received. Further, the radio signal receiver 300 that has received the radio signal from the light emission control device 200 transmits information on the radio signal to the control device 100 . The storage unit 120 of the control device 100 stores coordinate information in the event space where each receiver 300 is installed in association with the ID information of each radio signal receiver 300 . Therefore, the coordinate information acquisition unit 112 of the control device 100 refers to the ID information of the wireless signal receiver 300 to identify the position coordinates of the wireless signal receiver 300 that has received the wireless signal from the light emission control device 200. can be done.

Also, the radio signal receiver 300 can measure the reception strength of the radio signal. When the radio signal receiver 300 provides information about the reception intensity of the radio signal to the control device 100, the coordinate information acquisition unit 112 of the control device 100 receives information about the reception intensity from the radio signal receiver 300 based on the information about the reception intensity. Distances up to 200 can be calculated. Alternatively, the wireless signal receiver 300 may calculate the distance to the light emission control device 200 and provide the control device 100 with information about the calculated distance. In this way, the coordinate information acquisition unit 112 of the control device 100 obtains the coordinate position of the wireless signal receiver 300 that received the wireless signal from the light emission control device 200 and the distance from the light emission control device 200 to the wireless signal receiver 300. Ask for Further, if the radio signals emitted by the light emission control device 200 are simultaneously received by two or more radio signal receivers 300, the coordinate information acquisition unit 112 obtains the coordinate positions of the two or more radio signal receivers 300 and their coordinates. Two-dimensional coordinates (x, y) or 3 It is possible to determine the dimensional coordinates (x, y, z). In this manner, the coordinate information acquisition unit 112 of the control device 100 can acquire (calculate) information on the current coordinate position of each light emission control device 200 in real time. Also, the control device 100 may transmit information on the current coordinate position of each light emission control device 200 to each light emission control device 200 .

In the above description, the control device 100 calculates the coordinate position of the light emission control device 200. However, the light emission control device 200 itself is caused to obtain its own coordinate position, and the calculated coordinate position is transmitted from the light emission control device 200. It is also possible to transmit to the control device 100 . For example, when the ball is operated outdoors, each light emission control device 200 may be provided with a GPS measurement device, and each light emission control device may measure the two-dimensional coordinates (x, y) of the current position.

The light emission data generation unit 113 can determine the light emission state of the light emission unit 240 of the light emission control device 200 based on the current coordinate position of each lighting device 1 (light emission control device 200) obtained as described above. . Specifically, light emission data for controlling the light emission state of the light emitting unit 240 is provided to each lighting device 1 according to the current coordinate position of each lighting device 1 in the actual space. As a result, uniform lighting presentation can be performed according to the current position information of each lighting device 1 . For example, it is possible to divide the inside of the event venue into a plurality of areas and make the colors of the lighting devices 1 belonging to a certain area similar in color, or control the emission color and emission intensity in a gradation throughout the entire event venue.

The light emission data generation unit 113 determines the light emission state of each lighting device 1 as described above, and generates unique light emission data to be provided to each lighting device 1 according to the result (or reads it from the storage unit 120). ). The light emission data is preferably data in a timeline format in order to control the light emission state of the light emission unit 240 of each light emission control device 200 for a certain period of time. The light emission control device 200 will control the light emission state of the light emitting section 240 for a prescribed period of time according to this light emission data. Since it is assumed that the illumination device 1 will move in space, it is preferable that the light emission data be frequently generated every short period of time. For example, the time for controlling the light emission state with one light emission data is preferably 1 to 60 seconds, more preferably about 10 to 30 seconds. The light emission data includes, for example, ID information unique to the light emission control device 200, information specifying the light emission start point, information specifying the light emission state, and information specifying the light emission end point. In this way, the light emission data for each lighting device 1 generated by the light emission data generation unit 113 is transmitted to the light emission control device 200 of each lighting device 1 through the wireless communication unit 130 .

Upon receiving the light emission data from the control device 100, the light emission control device 200 of each lighting device 1 controls the light emission state of the light emission unit 240 by the light emission control unit 211 according to the light emission data. Further, for example, the light emission control unit 211 may store once received light emission data in the storage unit 220, and repeatedly perform control according to the same light emission data until the next light emission data is received from the control device 100. .

Next, processing for changing the light emission state according to the operation of the oscillator 2 will be described. The light emission control device 200 includes a motion detection unit 250 including an acceleration sensor, an inclination sensor, and the like. The motion of the moving body 2 is detected. When the motion detection unit 250 detects a sudden motion of the oscillator 2 (specifically, the amount of change in acceleration or angular velocity that exceeds a predetermined threshold), the light emission control unit 211 controls the light emission unit It is also possible to change the light emission state of 240 . For example, the light emission control unit 211 may randomly change the light emission color of the light emitting unit 240, or may appropriately change the light emission state such as blinking the light emitting unit 240 while the motion is being detected.

Further, in the light emission data generated by the control device 100, a method for changing the light emission state of the light emitting section 240 when the light emission control device 200 detects a sudden movement of the oscillator 2 may be defined. For example, in the light emission data, it is possible to prescribe, in advance, the color of the light emitting section 240 that is to be changed when a sudden movement of the oscillator 2 is detected. In this case, the light emission control section 211 may change the light emission state of the light emission section 240 according to the light emission data when the abrupt motion of the oscillator 2 is detected.

Further, when a certain light emission control device 200 detects a sudden movement of the oscillator 2, the light emission control section 211 not only changes the light emission state of its own light emission section 240, but also transmits detection information of the movement. It can be transmitted to another light emission control device 200 via the wireless communication unit 230 in a peer-to-peer manner. In this case, the other light emission control device 200 that has received the detection information changes the light emission state of its own light emitting unit 240 based on the detection information. By doing so, it is possible to change the light emission state of another lighting device 1 (oscillating body 2) in conjunction with the operation of a certain lighting device 1 (oscillating body 2). In addition, by connecting the light emission control devices 200 in a peer-to-peer manner, the light emission control devices 200 can be interlocked without going through the control device 100, so that interlocking of light changes can be speeded up. can be done.

FIG. 3 shows an example of the motion of the oscillator 2. As shown in FIG. As shown in Fig. 3(a), the bottom surface of the rocking body 2 is bowl-shaped, so it will tilt when pushed or hit by the audience. Because it is arranged, it will be raised by its weight.

3(b) schematically shows the tilting angle of the rocking body 2. As shown in FIG. The symbol θ1 shown in FIG. 3B indicates the tilting angle range of the rocking body 2 with respect to the horizontal direction (specifically, the ground or the floor). Examples of the angular range θ1 are 10 to 45 degrees or 0 to 30 degrees. For example, when the motion detection unit 250 (specifically, the tilt sensor) of the light emission control device 200 detects that the tilt angle of the rocking body is within the angle range θ1, the motion detection unit 250 (specifically, the acceleration sensor ) detects an abrupt motion, the light emitting state of the light emitting unit 240 does not change. In other words, when the spectator strongly pushes the upper part of the rocking body 2, the rocking body 2 receives the first impact from the audience's pushing motion, and then receives the second impact when it contacts the ground. . In such a case, in order to change the lighting state when receiving the first impact from the audience, and not to change the lighting state when receiving the second impact due to contact with the ground, the change of the lighting state is turned off. An angle range θ1 is defined in advance.

Instead of the angle range .theta.1 for turning off the change in the light emitting state as described above, an angle range .theta.2 for turning on the change in the light emitting state may be defined. That is, the reference θ2 shown in FIG. 3(b) indicates the tilting angle range of the rocker with respect to the extension direction. Examples of the angular range θ2 are 10-45 degrees or 0-30 degrees. For example, only when the motion detection unit 250 (specifically, the tilt sensor) of the light emission control device 200 detects that the tilt angle of the rocking body is within the angle range θ2, the motion detection unit 250 (specifically, the acceleration The light emitting state of the light emitting unit 240 is defined to change when the sensor detects a sudden movement. In this manner, the angular range within which the light emission state can be changed may be defined in advance.

Also, when changing the light emitting state of the light emitting unit 240, the speaker 270 may simultaneously output a sound such as a sound effect. That is, when the motion detection unit 250 detects a sudden motion of the rocking body 2 (specifically, the amount of change in acceleration or angular velocity exceeding a predetermined threshold), the sound control unit 213 causes the storage unit 220 to store the motion. Sounds such as sound effects are output from the speaker 270 based on the sound data. The sound output from the speaker 270 may change each time the oscillator operates, or may continue to output a constant sound.
