Description

  The present invention relates to a control method for centrally controlling light emission modes performed by a group of light emitting effects gathered at a certain venue or the like by wireless means.

  For example, in a gathering such as music or other events, if the lighting effect tools possessed by a large number of spectators and the like emit light at the same time, a very high effect can be obtained. A technique made with such an intention is described in Patent Document 1 below. Moreover, the following patent document 2 describes the example of the light emission effect tool which has not been used for such a purpose conventionally.

  In the technique described in Patent Document 1, a light emitting unit that emits an infrared signal including a control signal is installed in a viewing area, and a stage device carried by a large number of spectators receives the infrared signal and includes a control signal included therein. And a predetermined operation instructed by the light emitting unit is performed.

  However, infrared transmission / reception devices are widely used for remote control of electronic equipment, etc., so there is an advantage that they can be obtained at a relatively low cost, but on the other hand, the signal travels straight and reaches the receiver even with a small shield. It is easy to leave some stage tools that cannot be controlled. As a countermeasure, the light emitting unit must be set at a height above the audience, which is an unfavorable restriction for the venue setup. In addition, infrared rays will inevitably enter the eyes of the audience, so there may be a risk of visual impairment.

  The light emission control circuit controls light emission of the light emitter so that when the motion signal exceeds a predetermined value, the light emission mode is different from the predetermined light emission mode required by the centralized light emission control device. It is characterized by.

  By comprising in this way, the light production effect which considered reaction (expression of the user's intention of the light production | presentation tool) of a spectator etc. is acquired.

It is a partial front view which shows an example.

  Embodiments 1 and 2 of the control method and two embodiments of the light emitting effect device used in the present invention will be sequentially described below with reference to the drawings.

  FIG. 1 is a block diagram of the first embodiment, and the present invention is composed of two types of devices, that is, a centralized light emission control device 100 shown in (a) and a light emission effect tool 200 shown in (b).

  The centralized light emission control device 100 is fixedly or semi-fixedly installed at a venue or place where an event or the like requiring a light emission effect is performed. It is an apparatus that is assumed to be operated mainly by the organizer, and at least one of the forms of light emission performed by the light emitting effect device 200, that is, the presence or absence of light emission, blinking, intensity, color, and their temporal change pattern. In order to perform control so as to be a predetermined one intended by the organizer, an operation of transmitting a wireless light emission control transmission signal is performed.

  The operation device 110 is a device in which an operator (organizer side) creates a light emission control transmission signal by his own real-time operation or by prior programming. Including. Upon receipt of the signal output, the control transmission signal generation circuit 120 puts a predetermined signal on the sound wave (for example, by modulating the ultrasonic wave as a carrier wave with the predetermined signal), and transmits the acoustic transducer as a light emission control transmission signal. 130 (consisting of a transmitter such as an ultrasonic transducer or a speaker). The control transmission signal creation means 120 (for example, circuit-like means is used) and the transmission acoustic converter 130 together form a control transmission signal creation device.

The sound output has no adverse health effects unless the sound pressure is excessive.
As the sound wave, an ultrasonic wave having a frequency higher than the audible range is suitable when it is not desired to affect the acoustic effect of the event. That is, the transmission output of the ultrasonic wave, which is a carrier wave, is modulated by a control signal for performing blinking of light emission or color designation.

  Ultrasound is relatively directional, but not as good as an infrared emitter. The degree of directivity can be sharpened or weakened by the frequency used and the configuration of the transmission acoustic transducer. For example, if the acoustic transducers are arranged on a plane and driven with the same phase, they become sharp, and if only one is used or the frequency is relatively low, the directivity becomes weak. Although the degree of directivity and the degree of shielding by other objects are various, there are fewer restrictions on the installation location or the like than using infrared rays (light rays), and adjustment can be made according to the purpose.

  In some cases, a sound wave having an audible frequency can be used as the light emission control transmission signal. For example, a narrow-band sound wave mixed in the performance sound is detected. Further, the sound generated by the heavy bass speaker used at the venue may be detected. In addition, the lighting directing device is made to recognize the sound of a part of the musical instrument for performance (sound of a specific frequency or the sound of a percussion instrument) or the sound itself generated from an instrument that gives other sound effects as a light emission control signal. It may be.

  The sound wave can also be used in water. For example, the transmission acoustic transducer 130 is submerged in a pool, and a performer of an underwater show (synchronized swimming, etc.) is provided with the light effect device 200, and the light emission mode is controlled by sound waves. Since this control sound wave signal is not easily leaked to the water audience, there is a high degree of freedom in use frequency.

  A sound wave signal as a light emission control transmission signal is transmitted from the central light emission control device 100 toward the group of light emission effect devices 200.

  The light emitting effect device 200 is a light emitting device that is assumed to be carried by an individual user (for example, a participant such as a spectator), and is a reception acoustic converter 210 that receives a radio wave including a control transmission signal (such as an ultrasonic transducer or an ultrasonic transducer). A reception circuit 220 that demodulates the reception signal and extracts a control output signal, and a light emission control circuit 230 that controls the light emission mode of the light emitter 240 by the light emission control signal that is the output thereof, for example, an LED And so on. A power source 260 is a light battery, for example, and supplies power to each circuit and the light emitter. The reception acoustic converter 210 and the reception circuit 220 together constitute a reception device. There may be a plurality of light emitters 240, and their emission colors may be different. The power supply 260 supplies power to a necessary portion in the light emitting effect device 200.

  The motion sensor 250 is an acceleration sensor, an angular velocity sensor, a strain sensor or a force sensor (for example, as a force sensor, which is attached to a part of a handle such as a handle) attached to a part of the light emitting effect device 200. A pressure sensor), and a signal corresponding to the type of motion (translational motion, rotational motion, and the direction of the motion and rotation axis) and intensity applied to the light emitting effect device 200, or the light emitting effect device 200 by motion. Or at least one of information such as the force transmitted from the arm to the light emitting effect device 200 is output as a motion signal.

  This motion signal is input to the light emission control circuit 230 together with the light emission control signal from the outside, and both are judged inside, and when the motion signal is stronger than a predetermined intensity or the motion has a predetermined characteristic ( For example, when the lighting effect is strongly shaken, rotated around a specific axis, or the gripping force of the handle changes, the light emission mode is different from the external control or is further modulated. Let

  With this configuration, for example, when a sympathizer is sympathetic to a music performance and you want to express it, you can add a modulation that increases the intensity of the light emission or makes the light emission rhythm finer, for example, by shaking the light effector strongly or holding it strongly. Can express their feelings and intentions. Of course, even if there is no external control signal, it is possible to control the light emission mode only by the motion sensor 250.

<Modification 1 of Example 1>
An equalizer function is included in the operation device 110 and the control transmission signal generation means 120 of the centralized control device 100, and light emission control is performed by the output. That is, a control signal is created based on an acoustic signal (frequency, volume, etc.) from a sound source, or a set control signal is modified. For example, if the frequency band of the acoustic signal is a low frequency (for example, 1 to 10 Hz) and is equal to or higher than a predetermined acoustic level, the light emitting effect device 200 emits blue light, and a higher frequency band (for example, 10 to 100 Hz) and a predetermined volume level. For example, a program for emitting green light and emitting red light when a higher frequency becomes strong is set up. Control of blinking is also good. The acoustic signal may be input and recorded in advance from a CD, music memory, or the like, or may be detected in real time from a performance venue using a microphone or the like. In this way, it is possible to perform light emission control that matches the musical idea.

<Modification 2 of Example 1>
The operation device 110 and the control transmission signal creation means 120 have a function of extracting and analyzing, for example, an audio signal in a song, and emits blue light to the light emitting effect device 200 in a time zone in which a normal part of the song is sung. If it is detected that it is a rust portion, it is possible to emit light in red or pink, or to change the blinking cycle. This audio signal may also be obtained and registered in advance from the recorded sound source, or may be obtained in real time from the event. This way, you can raise the emotion of the singer and convey it to the audience.

  Next, although not using drawings, Example 2 will be described. In this example, the transmission acoustic transducer 130 is used to transmit a sound wave having a moderately strong directivity, so that the light emission control transmission signal reaches only a part rather than the whole group of light emitting effects. It is. By doing so, it is possible to give a different light emission mode to the part (remaining part) to a part of the light emitting effect tool, and to give a different characteristic to the effect effect by light depending on the place. Further, the direction of the transmission acoustic transducer may be moved to shift the group of light emitting effects on which the control signal acts with time.

  Normally, sound transducers such as speakers that have directivity have the strongest sound pressure in the direction of the central axis, and the direction of measurement points that surround the sound generation center of the acoustic transducer at equal distances deviates from the central axis. The sound pressure decreases. The sound pressure curve (radar chart) has a substantially elliptical shape with the sound generation point as the major axis end, or a water drop shape with the sound generation point as a cusp and a blunt apex on the central axis. The angle between the two directions on both sides of the central axis where the sound pressure is half (−3 dB) on the central axis may be used as an index representing directivity with a half-value width. When the angle goes out of the half-value width, the sound pressure generally decreases rapidly.

  Directivity varies depending on the frequency used, the structure of the acoustic transducer, the array arrangement of the same type of transducer, and the presence of reflectors. It is transmitted. The directivity is within, for example, a radiation angle of 150 °, and the superdirectivity (using ultrasonic waves) is 20 ° to 30 °. (This radiation angle is expressed by the bodily sensation and does not correspond exactly to the above half-value width, but is an angle that serves as a guide for directivity, and it is considered that there is no significant difference.)

  In an event venue, the spectator seats are usually spread around the stage at a large angle (90 ° to 360 °) in a plane, so that directivity in the horizontal direction is important. (There are cases where the audience seats are tilted down in the direction of the stage, or there are a few seats on the second and third floors, but the vertical angle is relatively small, so it is often not necessary to consider.)

  When it is intended to change the light emission mode of only a part of the group with respect to the total number of the light emitting effect devices 200 possessed by the spectator spread in a substantially planar manner, the number of the light effect effect devices 200 belonging to the group. (Since it may be considered that the reception acoustic transducer 210 is unsuccessfully received due to a decrease in sensitivity due to a lack of reception sensitivity due to an inappropriate orientation of the reception acoustic transducer 210 of the light emitting effect device 200, From the viewpoint of the light effect, the upper limit is about 70% of the total number, and the lower limit is the total number. It will be about 10%. It is also preferable that the range is 50 to 20%.

  The transmission acoustic transducer 130 that transmits the control transmission signal may be installed on the stage or in the back of the stage, for example, but the acoustic transducer 200 is within the range described above. With a directivity (half-width or nominal radiation angle is in the range of, for example, 20 ° to 150 °), the audience seats surround the stage at any angle between 90 ° and 360 °, for example. It is apparent that a preferable partial light emission effect can be obtained.

  In addition, by changing the direction (installation angle) in which the transmitting acoustic transducer 130 having directivity is directed with time, some groups having different light emission modes move within the audience seats. An effect can be obtained. Further, not only the angle change but also the position may be changed. For example, an acoustic transducer 130 having strong directivity is placed near the front edge of the stage, and a rail (straight line or curved line) is placed along the front row of the spectator seat with the direction in which the sound pressure is strongest facing the front. ) Or the like may be moved.

<Modification 1 of Example 2>
If a plurality of centralized light emission control devices 100 that transmit directional sound waves are used, each of which is responsible for different groups of light emitting effect devices 200 and controlled by different signals, it gives a remarkable specificity to the effect of light. be able to.

<Modification 2 of Example 2>
A centralized light-emission control device 200 that transmits sound waves with less directivity and a centralized light-emission control device 200 with strong directivity are used together, and the control contents of both are made different. With this configuration, for example, only a part of a group of light-producing effects that emit light substantially uniformly can be given light emission in a mode different from the others, and further diversity can be given to the light effect. However, since a part of the light emitting effect device 200 receives radio waves including different control signals, the receiving circuit 220 and the light emission control circuit 230 are configured to support both different signals.

<Specific example 1 of light-emitting director>
2-4 shows the structure of the specific example 1 of the light emission effect tool 200. FIG. 2 (a) is a front view of the whole, FIG. 3 (b) is a side view thereof, FIG. 3 (a) is a front view of the skeleton, FIG. 2 (b) is a side view thereof, and FIG. .

  The light emitting effect device 200 may be in the form of a stick, a penlight, or any other form, but can also be in the form of a light emitting fan as in this embodiment. Since the fan that emits light has a large fan surface, the light effect is greater than that of a small light effect device. First, its basic structure (a substantial part of which is in common with the light-emitting fan described in Patent Document 2) will be described, and the configuration unique to this embodiment will be described therein.

  2 and 3, reference numeral 1 denotes a fan skeleton, which is formed from a transparent material such as acrylic resin, and its main part is a skeleton base 1 a having a large thickness (the outer shape of the front view is an ellipse with pointed left and right). The upper base upper end 1c is composed of a large number of radiating bones 1g (those between which are window portions 1h having no members) and a substantially circular edge member 1f connecting the tips thereof. Yes. The portion of the skeleton base portion 1a has a large number of shallow recesses 1j on both surfaces thereof, and an intermediate portion thereof remains as a pseudo bone 1k. A light incident portion 1b is cut in the vicinity of the radiation center 1g, pseudo bone 1k, and recess 1j, and a mounting portion 1d and a decorative elongated hole 1i are formed on the left and right sides thereof. The skeleton 1 is a main light guide for light emitted from the light source.

  The fan handle 4 is composed of two members sandwiching the fan face, and is assembled with the lower part of the skeleton 1 sandwiched therebetween. In the lower part of the figure, the handle 4 is assembled into a cylindrical shape, and a battery 3e such as a AAA type serving as a power source for the light emitting effect device 200 is accommodated therein. The joint portion 4a having an enormous shape on the upper left and right sides is firmly coupled to the skeleton 1 by fitting the pin-shaped protrusions (not shown) therein and the fixing holes 1e of the attachment portion 1d of the skeleton 1.

  In the internal space of the coupling portion 4a, the light emission control circuit 230 is housed so as to overlap the LED 3a serving as the light emitter 240 of FIG. Although the arrangement of the receiving circuit 220 is not shown, it may be integrated with the light emission control circuit 230. Although the reception acoustic transducer 210 is not shown, a small microphone or ultrasonic wave receiver is provided on either the outside of the handle coupling portion 4 a, the skeleton 1, or a part of the fan plate 2.

  Although only one LED 3a corresponding to the light emitter 240 is illustrated, the emission color is not limited to a single color, and is preferably a plurality of colors. That is, a plurality of LED chips having different emission colors may be built in one package, or packages having LED chips having different emission colors may be arranged close to each other to form the light emitter 240. The light emission of each color of the light source is independently controlled by the light emission control circuit 230.

  Each terminal of the LED 3a, the positive electrode at the upper end of the battery 3e connected in series, and the upper end of the negative electrode lead wire 3d extending upward from the battery spring 3f at the lower end of the battery 3e via the main switch mechanism to the inside of the handle 4 are all It is connected to the light emission control circuit 230 (detailed structure is not shown).

  The cap 5 fitted to the lower end of the handle 4 also serves as a main switch for the power source. When the cap 5 is rotated after the battery is stored, the battery is wound into a conical coil shape fitted into the spring base 5a inside the cap 5 by the action of the internal protrusion 5b and the cam groove provided at the lower end of the handle 4. The lower end of the spring 3f and the negative lead wire 3d are in contact with each other, and the power supply circuit is closed. Turning it back turns off the power. The hanging ring portion 5c provided at the lower end of the cap 5 is for hanging a fan on the neck or wrist through a string or a chain.

  The light emitting part of the light source LED 3a is located at the center of the thickness of the skeleton base 1a at the light incident part 1b, and the light beam enters the skeleton 1 and spreads radially over the entire fan surface. In the process, if there is a portion having a cross-sectional change in the skeleton 1, particularly a portion in which the cross-section is suddenly shrinking and changing, it is emitted from there and shines. Each bright spot in FIG. 2 indicates a cross-section decreasing portion that is a main light emission point. The bright spot 6a is the lower end of the recess 1j, the bright spot 6b is a portion that moves from the base upper end 1c to the radiation bone 1g, and the bright spot 6c is a portion where the light reaches the outer end of the edge member 1f.

  In this example, a large number of main light emission points are closely arranged on several arcs, and in the dark place, these bright points are connected in a curved line and are extremely beautiful. Note that some light is emitted from other portions and uneven portions on the surface of the skeleton. The fan plate 2 also diffuses light emission. These look beautiful like halos. Even if a horizontal bone is provided, the emission point can be increased. In addition, it is convenient in terms of light emission and fan strength that the cross-sectional thickness and width of the skeleton 1 gradually decrease from the skeleton base 1a toward the edge member 1f.

  Since the light emission of the light source LED 3a is strong, it may feel dazzling when directly viewed. Since the handle 4 wraps both sides of the LED 3a, the difficulty can be overcome by selecting the light transmittance of the material. In other words, an opaque material may be used as the material for covering the LED 3a (in this example, the coupling portion 4a). However, glare is moderately suppressed when molded with a light-attenuating, that is, transparent, dark resin material. In addition, the presence of the light source can be clearly indicated to add further aesthetic effects.

  The fan plate 2 which is a transparent or translucent thin film or sheet is attached to both surfaces of the radiation bone 1g and the edge member 1f, and has a pattern 2a on the surface. This is a wind-up surface caused by a fan fan operation, and exhibits the aesthetic effect of a fan in a bright place, and has the role of preventing the light emission of the fan face as much as possible in a dark place. A transparent hologram sheet was optimal.

  Although the illustration of the movement sensor 250 is omitted in this example, it is optimal to arrange the movement sensor 250 in the enormous internal space of the mounting portion 1d of the handle 4 as in the light emission control circuit. However, if the motion sensor is a thin-film strain sensor that detects the deflection of the fan surface caused by strongly fanning the fan, it may be provided on the upper surface of the fan plate 2 and the grip strength of the handle 4 is detected. In the case of a force sensor, it may be arranged on the handle 4. Also, a plurality of LEDs 3a may be provided, and their light emission colors may be made different, or the light emission mode may be controlled separately to increase the light effect.

  As the motion sensor 250, it is conceivable to use a piezoelectric film or a thin plate (preferably light-transmitting so as not to prevent light emission) as at least a part of the fan plate 2. The fan plate is configured to detect that the fan has been shaken strongly and the fan surface has been bent. Further, when a piezoelectric fan plate is used, it can function as a reception acoustic transducer 210 that receives a sound wave serving as a light emission control signal. Since a large area can be used, high sensitivity can be expected. It is more preferable that one piezoelectric plate has both functions of the motion sensor 250 and the reception acoustic transducer 210. Alternatively, both functions may be shared by one side of the fan surface.

  Note that the light emission of the LED 3a is not only controlled by the light emission control signal emitted by the centralized light emission control device 100 or the motion sensor of the light emitting effect device itself, but also by a simple switch operation of the user and other signals. It is desirable to keep it.

<Specific example 2 of light-emitting director>
FIG. 5 shows the structure of a specific example 2 of the light emitting effect device 200. (A) is the whole front view, (b) is a side view. FIG. 6 shows the skeleton, where (a) is a front view, and (b) and (c) are a partial cross-sectional view and a partial front view showing two examples of changes in the cross-section of a single radial bone.

  This example is also a light emitting fan, and uses a translucent skeleton 1 and a translucent fan face plate 2 and incorporates a power source in the handle 4 with respect to the first embodiment of the illuminating effect tool shown in FIGS. There is commonality. The main difference from the previous example is that the connecting portion 4a of the handle 4 and the skeleton 1 is in the center of the disc-shaped (ring-shaped) fan, and the front view is almost omnidirectional (only the direction occupied by the handle) The light emitter emits light over a wide angle. In addition, the same code | symbol was attached | subjected to the component which has commonality with a previous example.

  The difference in effectiveness is that the upper end of the handle 4 reaches the center of the disk-shaped fan surface, so even if the same number of batteries as the previous example is built in, the vertical length of the fan can be shorter, The round fan is compact as a whole, and all directions of light emission are divided into a plurality of parts, and each angle range is assigned to a separate or plural set of LEDs 3a. It is obtained and the visibility from the outside is also high, and an excellent light effect is obtained.

  First, when each radiating bone 1g has a simple long rectangular parallelepiped shape, there are two kinds of luminescent spots as light emitting sites in this example, 6b being an intermediate point of the radiating bone 1g on the outer periphery of the circular skeleton base 1a, 6c which is the outer end of the edge member 1f on the extension of the radial bone 1g. In addition, it is desirable that the outer diameter of the coupling portion 4a is slightly smaller than the diameter of the skeleton base portion 1a so that the light emitted from the bright spot 6b can be seen well.

  It is also possible to emit light from the middle of the bone by giving a cross-sectional change to the radiation bone 1g. 6B shows a shape in which a stepwise cross-sectional change is given in the thickness direction of the fan surface, and FIG. 6C shows a shape in which a cross-sectional change is given in the width direction. In either case, light passing through the bone leaks from the point 6d where the cross section suddenly changes in the middle of the radiation bone 1g, and each becomes a bright spot.

  As shown in FIG. 6A, the bright spot 6d generated on the ring-shaped fan surface reminds the figure 50. In the case of this figure, three identical rhombuses are visually recognized. When the three LEDs 3a that individually illuminate these figures 50 are sequentially switched and lighted at an appropriate repetition rate, the figures 50 also blink sequentially on the fan surface, so that the figure 50 is rotating. Effects can be obtained. If the number of LEDs 3a and the number of figures 50 are increased, the movement becomes smoother. When the number is two, alternate lighting is performed.

  The light emission control circuit 230 (and the receiving circuit 220) and the motion sensor 250 for detecting acceleration and angular velocity are preferably housed inside the handle coupling portion 4a as shown in FIG. Further, as described in the first and third embodiments, a wide fan surface may be used by providing a pressure sensor on the handle or a piezoelectric film on the fan surface.

  As another formation structure of the bright spot, although not shown, the diameter of the skeleton base portion 1a may be larger than the outer diameter of the coupling portion 4a, and a shallow concave portion may be provided in the generated ring-shaped space. Alternatively, the skeleton 1 may be a transparent flat plate having no radiating bone, and a figure may be engraved on the flat plate to change the cross section for light emission.

<Specific example 3 of light-emitting director>
Make the lighting effector recognize the sound of some musical instruments for performance (sounds of a specific frequency or percussion instruments) or the sound itself generated from other instruments that give sound effects as a lighting control signal. Also good. In this case, even if the control transmission signal generation circuit 120 is not separately provided, the sound generation mechanism of the musical instrument or the device itself corresponds to the control transmission signal generation device in which the control transmission signal generation unit 120 and the transmission acoustic converter 130 are combined. The centralized light emission control device 100 is directly used as a musical instrument or device. In the case where the group of light emitting effect devices 200 has this function, the light effect can be obtained without a separate concentrated light emission control device. Of course, the centralized light emission control device 100 may be used in combination.

  The light emitting effect device 200 that recognizes the sound of a musical instrument or the like as a light emission control signal, for example, identifies a specific sound of a percussion instrument (such as a Japanese drum or a percussion musical instrument) by a waveform or a frequency component, and receives the specific sound to indicate how to shine Can produce visual effects in addition to acoustic effects.

  Alternatively, if you place a small group of light-emitting effects that are set to recognize and emit light from instruments and singers in different scales, you can change the scale of the song or performance by arranging them for each audience seating area. The small group that emits light changes accordingly, so that a new light production effect according to the progress or change of the music can be obtained.

  Similar effects can be obtained by applying different scales to the centralized light-emission control device 100 that transmits a directional light-emission control signal as in <Modification 1 of Example 1> and <Modification 2> described above. This can also be achieved by recognizing (by a program based on real-time sound detection or music) and transmitting different light emission control signals, and controlling light emission of different small groups of light-emitting effect devices 200.

  One or a small number of conductors (for example, artists or singer who will be the main role of the event, usually designated by the organizer) determine the light emission mode of the light directing device 200 that each audience at the event venue has. It is a configuration that can be freely controlled. The conductor carries or wears a motion sensor and a transmitter for transmitting the detected motion information to the outside. The signal transmission between the transmitting transmitter and the centralized light emission control device 100 is preferable because wireless means such as radio waves, sound waves, or light (for example, infrared rays) are less restricted when moving, but may be wired.

  The control transmission signal generation means 120 of the centralized light emission control device 100 includes means for receiving a signal from a transmitter and means for discriminating exercise information included in the signal, and the light emission possessed by the audience based on the exercise information. It has a function of transmitting a predetermined control transmission signal to the director 200. That is, when it is detected that the signal output has changed, the centralized light emission control device 100 selects a light emission pattern registered in advance and performs control so that the light emitting effect device 200 emits light.

  “Motion” in motion sensors (generally also referred to as motion sensors) has a broad concept. Some examples are shown. First, as described in the description of [Embodiment 1], there is a sensor that detects acceleration, angular velocity, strain, and force (each of which can be detected from one axis to three axes) acting on a mounted object.

  In addition, a light receiving pyroelectric sensor that can detect infrared rays emitted from the human body and detect position information can also be used (the sensor is placed at a fixed position, for example). There is also a reflective sensor that emits infrared rays or electromagnetic waves (such as microwaves) and detects reflected light or reflected waves from the human body. Further, by detecting the phase difference between reflected light or reflected waves from the object (human body), the position of the object and its change can be detected. It is also possible to arrange the detectors of reflected waves in an array to identify the motion of a plurality of objects.

  With such a configuration, to give a simple example, the conductor has a conductor rod, a cane, a stick or the like equipped with a motion sensor for detecting acceleration, or a motion sensor is mounted on the conductor's own arm. When the output of the motion sensor exceeds a certain threshold by strongly shaking the cane or the arm, it is possible to easily produce an effect such as instantly changing the light emission color of the light emission effect device 200 possessed by all audiences to red all at once. Further, when the conductor moves on the stage and comes to a predetermined position, the light emission modes of a large number of light emitting effects can be changed simultaneously.

  In addition, the conductor himself possesses a light emitting effect device capable of operating the light emission mode by himself / herself, and a motion sensor is incorporated in the light emission effect device, and the movement of the conductor is transmitted to the central light emission control device 100. Then, the centralized light emission control device 100 detects the light emission operation performed as planned or improvised by the conductor, and the audience light-emitting effect device 200 can be caused to emit light synchronously in the same pattern.

  Further, when the concentrated light emission control device 100 transmits the light emission control signal generated by the trigger given by the conductor toward the light emitting effect device 200, the transmission acoustic converter 130 having directivity is used and the directivity thereof is used. By changing the direction of sex automatically or manually in time, for example, the light can be emitted in a sweep or wave manner so that the light mass moves from end to end of the event venue.

  It should be noted that the light-emitting staging device possessed by the conductor does not intentionally include a motion sensor that continuously measures motion, such as an acceleration sensor, but merely tells the centralized light-emission control device 100 that the light-emitting switch has been pressed. The signal transmission device functions as a simple motion sensor that detects the motion of the conductor's switch operation.

  In addition, the centralized light emission control device 100 and the light emission effect device 200 include any of the above-described embodiments as a basic function. In addition, the light emission effect device 200 possessed by the conductor or the spectator has a mutual function. By installing and functioning a device that changes the light emission mode according to the distance, the light emission effect can be further diversified.

  Of course, it is possible in principle to detect a continuous change in the distance between a large number of light-emitting effect devices 200, but if this is not easy, it is detected that two light-emitting effect devices 200 are in contact with each other. Also good. In this case, since a sudden force, acceleration, or distortion is generated in the light-emitting effect device that has come into contact, the motion sensor 250 provided in the light-emitting effect device 200 can be used.

  One light is emitted and the other is non-lighted (or may have different light emission forms (for example, different light emission patterns and colors)), two light emitting effects devices 200 are in contact with each other or approached within a predetermined distance At this time, for example, it is possible to use the light-emitting effect device 200 that is manually operated with the light-emitting switch as a master and transmit the light-emission mode to the latter light-emitting effect device 200 that is a slave that is not operated for light emission. This can be realized by adopting a configuration in which a light emission mode is fixed by a (forced) light emission operation and a passive light emission mode according to another signal is taken when the (forced) light emission operation is not performed. This function is given to the light emission control circuit 230.

  According to this configuration, the light emitting effect device 200 possessed by the conductor is used as the first master, and the light emitting color and pattern are first transmitted to the light emitting effect device 200 (slave) possessed by the audience in the front row. Next, the same light emitting mode is transmitted with the light emitting device 200 of the user as the master and the light emitting device 200 of the audience in the back row as the slave. When this is repeated, there is obtained an effect that a predetermined light emission pattern or color moves and changes in a wave shape from the front edge of the hall to the rear.

  In order to specify the light emission color and light emission pattern at the time of transmission, the signal is generated by the control transmission signal generation means 120 and transmitted from the centralized light emission control device 100 to each light emission effect device 200, or each issue effect is previously determined. It is set using a manual switch or the like on the tool 200 side. Each light emitting effect device 200 may include a sensor that can directly recognize the light emission color and light emission pattern of the master.

  Although the use of sound waves has been described above as the medium for the light emission control signal, it is also possible to use radio waves or infrared rays as the carrier wave for the light emission control signal. Radio waves, sound waves, and light rays (infrared rays) have advantages and disadvantages with respect to reachable range and range, directivity, ease of shielding, interference from others, ease of implementation of transmission and reception devices, and the like. Considering each feature, you can use either of them as a signal medium or use them together, and configure the centralized lighting control device and lighting effect tool so that they can be switched according to the situation. Good. In addition, by combining the configurations of the above-described embodiments and modifications, a characteristic light emission effect can be obtained.
