Description

  The present invention relates to an effect method, an effect system, and a portable light-emitting device, and more specifically, a portable light-emitting device such as a penlight, fan, batch, hat, or Mickey Mouse ear that has a built-in IC tag and can emit light The present invention relates to an apparatus, an effect method that realizes a desired optical effect in a venue such as a concert hall or a stadium, and an effect system that realizes the effect method.

  Conventionally, in venues where various events such as concerts and plays are held (hereinafter referred to as event venues), all or part of the lighting is often turned off when the events are executed. This is to enhance the optical effect. On the other hand, according to the music played on the stage, it has also been conventionally practiced that individual spectators swing slowly with a penlight at the spectator seat to enhance the sense of unity between the performer and the audience. As described above, when a portable light-emitting device such as a penlight is used in a darkened event venue or a night outdoor stage, the effect is great.

  As an example of the portable light emitting device, there is a “circular light emitter” disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2002-315617). This is because “the handle that houses the power supply inside, the transparent substantially plate-shaped fan member joined to one end of the harmful handle, and the handle so that the speed of light is incident on the inside of the fan member. At least one LED light source disposed near one end of the LED, means for radiating a part of the speed of light from the fan surface, and preventing light leakage from the vicinity of the LED light source to the outside of the fan member It is characterized by having a light-shielding member that performs (refer to claim 1). According to this fan-shaped light emitter, an excellent and beautiful light effect can be obtained, the strong direct light of the LED does not hinder the visibility of delicate light from the fan surface, and the manufacturing cost is low. It is said that there is.

  Further, with respect to effects using a portable light emitting device, there is “light emitting device for effect and effect method by portable light emitting device” disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2002-36981). This light emitting device for production includes a plurality of portable light emitting devices and a light emission state control device, and the light emission state control device wirelessly sends an address and a light emission command signal allocated to each portable light emitting device, and each portable light emitting device emits light. Light is emitted based on a self-addressed light emission command signal sent wirelessly from the state control device (see claim 1). In addition, this directing method allocates an address of the portable light emitting device corresponding to the position of each spectator seat, and causes the spectator of the spectator seat to carry the portable light emitting device of the address assigned to each spectator seat, An image by light emission of the portable light emitting device similar to the light emission state image created by the issuing state image creation means is formed on the audience seat (see claim 6).

  Patent Document 3 (Japanese Patent Laid-Open No. 62-40101) discloses a “stage effect method” using a light emitting device equipped with a receiver. In this stage production method, light-emitting devices equipped with receivers are distributed in audience seats such as a theater or a stadium, and these many light-emitting devices are blinked by radio waves sent from a wireless transmission device or the brightness is changed. (See claims).

On the other hand, in recent years, wireless IC tags (hereinafter also simply referred to as IC tags) have been used instead of barcodes. An IC tag is also called an “electronic tag” and is composed of a small wireless IC (integrated circuit) chip used to identify an object, and records information such as its own identification code. Has the ability to send and receive information to and from the management system. The size of the IC tag is usually about several centimeters, and a memory, a wireless antenna, and a communication function are incorporated. There are various shapes such as a label type, a card type, a coin type, and a stick type. The communication distance is often several mm to several m.
The IC tag receives and transmits radio waves by the "active type" that receives and transmits radio waves with a built-in power supply (battery), and does not have a built-in power supply and is driven by electromagnetic induction caused by incoming radio waves. There is "passive type". The former can communicate even at a distance of several tens of meters, but cannot communicate when the battery is exhausted, and is more expensive than the passive type. The latter has a communication distance of about several millimeters to several tens of centimeters, but can be manufactured semipermanently because it can be manufactured much cheaper than the active type and there is no fear of running out of the battery.
The specific configuration of the IC tag is described in, for example, Japanese Patent Application Laid-Open No. 2001-325572, Japanese Patent Application Laid-Open No. 2005-208787, and the like and is not described here because it is known.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited thereby.

(Configuration of production system)
FIG. 1 is a conceptual diagram showing an effect system 1 according to an embodiment of the present invention. By this presentation system, the presentation method according to an embodiment of the present invention is realized.
This production system 1 includes a plurality of portable light emitting devices 30, a plurality of light emission state control devices 10 that control the light emission states of the portable light emitting devices 30, and a plurality of light emission state control devices 10 (and thus the production system 1). A personal computer 22 is provided as a central control device for controlling the operation. In FIG. 1, for simplicity, only one portable light emitting device 30 and one light emitting state control device 10 that controls the light emitting state of the portable light emitting device 30 are illustrated.
The personal computer 22 is connected to the hub 21 via a LAN (Local Area Network) cable 24. The hub 21 is connected to the light emission state control device 10 via the LAN cable 23. The LAN cables 23 and 24 comply with the 10/100 BASE TX standard.

  As described above, the plurality of light emission state control devices 10 and the personal computer 22 are mutually connected via the LAN cables 23 and 24, the hub 21 and other similar LAN cables and hubs (none of which are shown). They are connected and constitute one LAN (information communication network within a specific area).

  The light emission state control device 10 includes an antenna 11, a wireless transmission / modulation unit 12, an encoder 13, a LAN-serial converter 14, and a power supply unit 15 that supplies a predetermined voltage thereto. The LAN-serial converter 14 converts data between the data transmission format when transmitted through the LAN and the data transmission format when transmitted via the serial interface, without changing the data contents. To do. The encoder 13 encodes the data converted into serial transmission by the LAN-serial converter 14 according to a predetermined method. The encoder 13 and the LAN-serial converter 14 are connected via a serial cable 16. The wireless transmission / modulation unit 12 modulates the encoded data in accordance with a predetermined method, and wirelessly transmits the signal via the antenna 11 using radio waves. The light emission state control device 10 (not shown) has the same configuration.

  Data sent to the LAN-serial converter 14 via the LAN is generated by the personal computer 22. Therefore, in order to realize a desired light emission state with a plurality of portable light emitting devices 30, data for designating such a light emission state is generated by the personal computer 22, and the data is transmitted to all the light emission states connected to the LAN. The data is sent to the control device 10, and the data is wirelessly transmitted from the light emission state control device 10 to each portable light emitting device 30.

  Next, the configuration of the portable light emitting device 30 will be described. The portable light emitting device 30 includes an antenna 31, a wireless reception / demodulation unit 32, a memory 37, a decoder / LED drive unit 33, an LED unit 34, a mode selector 35, and a power supply unit 36. . A portable light emitting device 30 (not shown) has the same configuration.

  The wireless reception / demodulation unit 32 receives the data transmitted wirelessly by the antenna 31 and demodulates the received data according to a predetermined method. The decoder / LED drive unit 33 drives the LED unit 34 in accordance with the demodulated data. The LED unit 34 incorporates three LEDs (Light-Emitting Diodes) that emit red (R), green (G), and blue (B) colors, according to the demodulated data. Various colors of light can be generated. The power supply unit 36 supplies a predetermined voltage to the wireless reception / demodulation unit 32, the decoder / LED drive unit 33, and the LED unit 34.

  The antenna 31, the radio reception / demodulation unit 32, and the memory 37 constitute a radio IC (Integrated Circuit) tag 40. The wireless IC tag 40 has almost the same configuration as a known one. That is, an identification code unique to the portable light emitting device 30 is stored in the memory 37, and the portable light emitting device 30 is identified from other portable light emitting devices 30 by reading the identification code. Can do. And the control signal of LED is received using the wireless communication function, and R, G, B three LED can be turned on and off, and a luminescent color can be changed.

  The mode selector 35 is for switching the operation mode of the portable light emitting device 30. The portable light emitting device 30 has a “remote mode” in which the light emitting state and operation can be remotely operated wirelessly from the personal computer 22 and such a remote operation is not possible. A “local mode” that is operated by the person himself / herself to control the light emission state and operation. Therefore, if necessary, the mode selector 35 is moved based on the data transmitted wirelessly, or a mode changeover switch (not shown) provided in the portable light emitting device 30 is operated. The portable light emitting device 30 can be operated in a desired mode.

(Operation of the production system)
Next, the operation of the production system 1 having the above configuration, that is, the production method using the production system 1 will be described.
The plurality of light emission state control devices 10 are arranged in the venue with a certain layout. Each of these light emission state control devices 10 has a predetermined communicable zone. For example, as shown in FIG. 2, three light emission state control devices 10 are arranged at the vertices of a certain triangle in the venue, and their communicable zones, that is, a first zone 51, a second zone 52, and a third zone 53. So that the edges of each other overlap. The three light emission state control devices 10 are connected to the personal computer 22 with a LAN cable. Since the communicable distance is determined by the specifications of the built-in IC tag, the size (radius) of the communicable zone can be estimated from the specifications. If each light emission state control device 10 is positioned based on the distance thus estimated, the end portions of the first zone 51, the second zone 52, and the third zone 53 can be overlapped with each other.
On the other hand, each of the plurality of portable light emitting devices 30 is carried by each of the visitors (audiences) to the venue. In addition, a visitor who carries the portable light emitting device 30 is allowed to stop at a position included in any one of the first to third zones 51, 52, and 53. For example, as shown in FIG. 3A, the first to third zones 51, 52, 53 are arranged inside. In this way, the light emitting state of the portable light emitting device 30 disposed in the first zone 51 is controlled by the light emitting state control device 10 disposed in the center of the first zone 51. The same applies to the second to third zones 52 and 53.

  As a result, when a control signal is sent from the personal computer 22 to each light emission state control device 10 via the LAN, the control signal is wirelessly transmitted from each light emission state control device 10 to the communicable zone. Then, the portable light-emitting device 30 in each communicable zone, that is, the first to third zones 51, 52, and 53 receives the control signal and enters a light-emitting state according to the content. At a certain timing, for example, as shown in FIG. 3A, all the portable light emitting devices 30 in the first zone 51 emit red light, and all the portable light emitting devices 30 in the second zone 52 are blue. All the portable light emitting devices 30 in the third zone 53 emit white light. In this way, a different light emission state can be realized for each communicable zone.

At the next timing, for example, as shown in FIG. 3B, all the portable light emitting devices 30 in the first zone 51 emit white light, and all the portable light emitting devices 30 in the second zone 52 are It emits red light, and all the portable light emitting devices 30 in the third zone 53 emit blue light.
If such a change in the emission color is repeated, the light emission point group of three colors of red, blue, and white will be switched for each communicable zone. As a result, the light emission point group of the three colors is changed to the first to third. It is possible to rotate around the centers of the zones 51, 52, and 53, and a high optical effect is obtained.

  FIG. 4 shows an example in which the production method is applied to a concert venue. The concert hall 60 generally has a stage 61 at the front end, and the other area is a spectator seat 62. In the spectator seat 62, a large number of chairs (seats) are arranged like a grid. Therefore, as shown in FIG. 4, nine light emission state control devices 10 are arranged in the spectator seat 62, and these light emission state control devices 10 are connected to the personal computer 22 with a LAN cable. Then, the communicable zones of the light emission state control device 10, that is, the first zone 71, the second zone 72, the third zone 73, the fourth zone 74, the fifth zone 75, the sixth zone 76, the seventh zone 77, the first zone 77, The ends of the eighth zone 78 and the ninth zone 79 are overlapped. Thus, the first to ninth zones 71 to 79 are laid out as shown in FIG.

  On the other hand, each of the plurality of portable light emitting devices 30 is carried by each of the visitors (audiences) to the concert venue 60 and seated in a designated (or desired) seat. Then, each portable light-emitting device 30 enters one of the first to ninth zones 71 to 79 depending on the position of the seat on which the audience is seated. In this way, the light emitting state of the portable light emitting device 30 disposed in the first zone 71 is controlled by the light emitting state control device 10 disposed in the center of the first zone 71. The same applies to the second to ninth zones 72 and 79.

  As a result, when a control signal is sent from the personal computer 22 to each light emission state control device 10 via the LAN, the control signal is wirelessly transmitted from each light emission state control device 10 to the communicable zone. Then, the portable light emitting device 30 in each communicable zone, that is, in the first to ninth zones 71 to 79 receives the control signal and enters a light emitting state according to the contents.

  At a certain timing, for example, as shown in FIG. 4, the portable light emitting device 30 belonging only to the first zone 71 emits white light, the portable light emitting device 30 belonging to only the second zone 72 emits red light, The portable light emitting device 30 belonging to only the three zones 73 emits blue light. Similarly, the portable light emitting device 30 belonging only to the fourth zone 74 emits blue light, the portable light emitting device 30 belonging to only the fifth zone 75 emits white light, and the portable light emitting device belonging to only the sixth zone 76. 30 emits red light. The portable light emitting device 30 belonging to only the seventh zone 77 emits red light, the portable light emitting device 30 belonging to only the eighth zone 78 emits blue light, and the portable light emitting device 30 belonging to only the ninth zone 79 is white. Flashes on.

  In the example of FIG. 4, unlike the example of FIG. 3, since two or more adjacent zones overlap, the light emission state of the overlapping portion is different from the light emission state of the other portions. In the example of FIG. 4, the portable light emitting device 30 belonging to the overlapping portion of two or more adjacent zones emits green light. This can be realized, for example, by setting each portable light emitting device 30 to emit green light when two or more control signals are received simultaneously. Needless to say, the light emission state of the overlapping portion may be any other light emission state. For example, the intensity of the control signals received at the same time may be compared, and the light emission state according to the strongest control signal may be set.

  Also in the example of FIG. 4, as in the example of FIG. 3, by changing the control signal of each light emission state control device 10 according to the passage of time, the light emission point groups in different light emission states are changed to the first to ninth zones. It becomes possible to change every 71-79, and a high optical production effect is acquired.

  FIG. 5 shows an example in which the production method is applied to a baseball field. The baseball field 80 generally has a ground 81 in the center and a spectator seat 82 around it. A large number of chairs (seats) are arranged in the spectator seat 82 toward the ground 81. Therefore, as shown in FIG. 5, a large number of light emission state control devices 10 are arranged in the spectator seat 82, and these light emission state control devices 10 are connected to the personal computer 22 with a LAN cable. And the communicable zone 90 of these light emission state control apparatuses 10 is adjusted so that the edge part may overlap. In this way, a large number of zones 90 are laid out along the audience seat 82 as shown in FIG.

  On the other hand, each of the plurality of portable light emitting devices 30 is carried by each of the visitors (audience) of the baseball field 80 and sits on a seat designated (or desired by the audience) of the audience seat 82. Get it. Then, each portable light-emitting device 30 enters one of a number of zones 90 depending on the position of the seat where the audience is seated. In this way, the light emitting state of the portable light emitting device 30 arranged in a certain zone 90 is controlled by the light emitting state control device 10 arranged in the center of the zone 90. The same applies to the other zones 90.

  As a result, when a control signal is sent from the personal computer 22 to each light emission state control device 10 via the LAN, the control signal is wirelessly transmitted from each light emission state control device 10 to the communicable zone. Then, the portable light emitting device 30 in each communicable zone receives the control signal and enters a light emitting state according to the content.

  At a certain timing, for example, the portable light emitting device 30 belonging to only one certain zone 90 emits red light, the portable light emitting device 30 belonging to only one other zone 90 emits green light, and the other one The portable light emitting device 30 belonging only to the zone 90 emits blue light. At the next timing, the portable light emitting devices 30 belonging only to the zone 90 to the right of the three zones 90 emit light in red, green, and blue, respectively. At the next timing, the portable light emitting devices 30 belonging only to the zone 90 that is further to the right of the three zones 90 emit light in red, green, and blue, respectively. In this way, when the light emission point group of three colors of red, green, and blue is sequentially moved around the ground 81 with the passage of time, a wave of three colors of red, green, and blue is generated in the audience seat 82. It is formed. Therefore, a high optical effect can be obtained at the baseball field 80.

(Configuration example of a portable light-emitting device used in a production system)
FIG. 6 shows a fan-shaped light emitter 100 which is a configuration example of the portable light-emitting device 30 used in the rendering system 1 described above. This configuration is almost the same as that disclosed in Japanese Patent Laid-Open No. 2002-315617.
The fan-shaped light emitter 100 includes a handle 104 and a fan 101 connected to one end thereof. The fan body 101 is composed of a plurality of radiating bones 101a, edge members 101b, and transverse bones 101c. The fan body 101 is integrally formed with a colorless and transparent resin material with a substantially constant thickness, and forms a structural fan skeleton. It is a light guide member. The plurality of radial bones 101 a reach the edge member 101 b radially from the bone concentration portion 101 d near the handle 104. The lateral bone 101c connects a plurality of radial bones 101a. An LED unit 103 including R, G, B three-color LEDs is built in a notch 101 e at the lower end of the fan body 101. The luminous flux generated / radiated from the LED unit 103 is mainly incident on the inside of the fan body 101 and guided into each radiation bone 101a.

  The lower part of the fan body 101 is covered with a light shielding member 102 so that the light flux generated and emitted from the LED unit 103 does not leak directly toward the user.

Inside the handle 104, a power source 105 and a wireless IC tag 106 are attached. As the power source 105, a commercially available battery is usually used. The wireless IC tag 106 can be realized by adopting a known configuration and adding a function capable of changing the light emission state of the LED unit 103 to the wireless IC tag 106.
A mode changeover switch 107 is attached to the outside of the handle 104. The operation mode of the fan-shaped light emitter 100 can be switched by remote operation, but the operation mode of the fan-shaped light emitter 100 can be switched at the discretion of the user.

  As described above, in the rendering system 1 according to the embodiment of the present invention, each of the plurality of portable light emitting devices 30 includes the IC tag 40, so that the light emitting state control device 10 stores the information in each IC tag 40. By individually transmitting the control signal using the identification code, the light emission state of the portable light emitting device 30 can be individually changed. Further, since each of the plurality of light emission state control devices 10 has a predetermined communicable zone, the light emission state of the portable light emitting device 30 in the communicable zone of one light emission state control device 10 is the light emission. This is in accordance with a control signal transmitted from the state control device 10. Therefore, the light emission state of the portable light emitting device 30 can be highly controlled by a relatively simple method.

  In addition, since the light emission state of the portable light emitting device 30 in the communicable zone is changed for each light emission state control device 10, the light emission state is changed for each certain range (area), and a complex moving image such as a wave of light. Can be easily formed.
