  However, Patent Document 1 only displays a pre-formed light emission pattern using a plurality of portable light emitting devices. For example, the light emission pattern of the portable light emitting device changes depending on the voice of a performer such as a singer in an event venue. Alternatively, the portable light emitting device cannot emit light in synchronism with a change in the voice of the performer.

  The present invention has been made in order to solve the above-described problems, and provides a light emission control system capable of causing a light emitting unit of a slave unit such as a portable light emitting device to emit light in response to a change in sound. For the purpose.

  The light emission control system according to the present invention is connected to an audio / signal converter having an audio / signal converter that converts external audio into an audio signal and a plurality of frequency selectors, and to the audio / signal converter. A control device, at least one master device connected to the control device, and a plurality of slave devices connected to the master device wirelessly and having a light emitting unit, the control device from the master device A signal that passes through each frequency selection unit among the audio signals is transmitted to each slave unit, and each of the slave units causes the light emitting unit to emit light based on the received signal.

Passes through the frequency selector. The control device transmits the signal from the parent device to the child device, and the child device causes the light emitting unit to emit light according to the received signal. In this case, since the frequency band of the performer's voice is different for each performer, light corresponding to the performer's sound is emitted from each light emitting unit. Accordingly, each of the light emitting units can express a unique light emission pattern of the performer, and can enhance the production of the event venue.

  In this case, the control device sends a light emission processing command composed of handset control data including handset identification data for identifying each handset and light emission information data corresponding to the audio signal, and synchronization data, Each of the slave units that are simultaneously transmitted from the master unit to each of the slave units and receive the light emission processing command determines whether or not the slave unit identification data is data indicating itself, and is data indicating itself. In this case, the light emitting section of the self may emit light at a timing determined by the synchronization data based on the light emission information data.

  By transmitting the slave unit control data from the master unit to the slave unit, a unique light emission pattern of the performer can be displayed on a desired slave unit among the slave units. Therefore, for example, it becomes possible to make each light emission part emit light by combining the light emission pattern and a light emission pattern such as a character or a picture, so that the event venue can be further enhanced.

  Each of the frequency selectors may be a filter that allows signals of different frequency bands to pass therethrough, and each of the light emitting units may emit different light based on the signals of the frequency band ( Invention of Claim 3).

  As a result, various lights are emitted from the light emitting units according to the frequency band of the sound, so that the event venue can be further enhanced.

  In addition, the luminance of each light emitting unit may be changed based on the amplitude of the signal in the frequency band (the invention according to claim 4).

  Thereby, since the brightness | luminance of each said light emission part changes with the sound volume in each frequency band of the said audio | voice, the effect of the said event venue can be heightened further.

  In addition, the light emission control system according to the present invention is connected to the voice / signal converter having a voice / signal converter and a plurality of frequency selectors for converting an external voice into a voice signal, and to the voice / signal converter. And a control device having a storage unit for storing the audio signal, at least one master device connected to the control device, and a plurality of slave devices each connected to the master device wirelessly and having a light emitting unit, The control device outputs the signals stored in the storage unit in time series while sequentially storing in the storage unit the signals that pass through the frequency selection units among the audio signals. The slave unit transmits the light to the respective slave units, and each of the slave units causes the light emitting unit to emit light based on the received signal (invention according to claim 5).

  In this case, the control device calls the signals stored in the storage unit in time series while storing the signals passing through the frequency selection units in the storage unit, and transmits the signals from the master unit to the slave units. Is sending to. Therefore, each said light emission part can light-emit in synchronization with the said voice of a performer.

  As described above, according to the present invention, in an event venue such as a stadium, a studio, or a hall, a voice of a performer such as a singer is converted into a voice signal by a voice / signal conversion unit, and a frequency selection unit among the voice signals Only the signal corresponding to the frequency band of the signal passes through the frequency selector. The control device transmits the signal from the parent device to the child device, and the child device causes the light emitting unit to emit light according to the received signal. In this case, since the frequency band of the performer's voice is different for each performer, light corresponding to the performer's sound is emitted from each light emitting unit. Accordingly, each of the light emitting units can express a unique light emission pattern of the performer, and can enhance the production of the event venue.

  Further, according to the present invention, the control device calls the signals stored in the storage unit in time series and stores the signals passing through each frequency selection unit in the storage unit, and transmits the signals from the master unit to each slave unit. doing.

(32) The light emission control of each of the light emitting units 22 (1) to 22 (32) in the case of arranging a square (shown by a broken line) corresponding to each spectator seat of the event venue.

  Here, in FIG. 6, the numbers in the squares indicate the numbers 1 to 32 of the audience seats, and the audience seats have handset number codes 1 to 32 that match the numbers 1 to 32. Assume that each slave unit 24 (1) to 24 (32) is arranged. In addition, for convenience, each spectator seat having the numbers 1 to 32 will be described as spectator seats 1 to 32 below.

  The master unit 14 (1) controls the slave units 24 (1) to 24 (8), the master unit 14 (2) controls the slave units 24 (9) to 24 (16), and the master unit 14 ( It is assumed that the slave units 24 (17) to 24 (24) are controlled from 3) and the slave units 24 (25) to 24 (32) are controlled from the master unit 14 (4).

  First, in the control device 12, the slave unit number codes 1 to 32 are allocated to the slave units 24 (1) to 24 (32), and the slave unit number codes 1 to 32 are assigned to the slave units 24 (1) to 24 (1). Each is stored in the first memory 50 of (32).

Each of the child devices 24 (17) to 24 (24) is stored in the first memory 50, and the parent device number code 4 is stored in the first memory 50 of each of the child devices 24 (25) to 24 (32). .

  The master unit number code is assigned to each of the master units 14 (1) to 14 (4) in order to identify the master units 14 (1) to 14 (4). Numbers 1 to 4 in parentheses 14 (1) to 14 (4) are referred to.

  Next, the control device 12 creates arrangement information shown in FIG. 6 in which the slave units 24 (1) to 24 (32) are arranged in an 8 × 4 matrix.

  Next, the slave units 24 (1) to 24 (32) are arranged in 32 spectator seats 1 to 32 in the event venue according to the arrangement information. In this case, each of the slave units 24 (1) to 24 (32) may be directly arranged in each of the spectator seats 1 to 32, or handed over to each spectator together with a ticket, and each spectator receives each spectator. You may make it arrange | position by sitting in the seats 1-32.

  Through such preparation, the performer inputs the voice of “A” shown in FIG. 5 through the microphone 16, and the voice is converted into an analog signal, which is an electrical signal, as shown in the flowchart of FIG. The analog signal is output to the signal conversion means 18 (step S1).

  In this case, among the analog signals input to the signal conversion means 18, a signal of 0 to 1 kHz passes through the first filter unit 36a and is amplified by the first amplification unit 38a, and a signal of 1 to 2 kHz is The signal of 2 to 3 kHz passes through the second filter unit 36b and is amplified by the second amplification unit 38b. The signal of 2 to 3 kHz passes through the third filter unit 36c and is amplified by the third amplification unit 38c. The signal passes through the unit 36d and is amplified by the fourth amplification unit 38d (step S2).

  Specifically, the voice of “A” has a high voice level in the frequency band of 300 Hz to 1.7 kHz, and the level drops at a frequency of 1.7 kHz or higher. Therefore, the analog signal of the voice is mainly the first. The light passes through the filter unit 36a and the second filter unit 36b and is amplified by the first amplification unit 38a and the second amplification unit 38b.

  Therefore, the respective signals output from the first to fourth amplification units 38a to 38d are converted from analog signals to digital signals in the first to fourth A / D conversion units 40a to 40d (step S3). In this case, each of the A / D converters 40a to 40d converts the analog signal into, for example, a binary signal of 3 bits (8 gradations).

  The analog signal based on the voice of “A” is converted into a digital signal (110 in binary number) indicating 7 levels of 8 gradations in the first A / D converter 40a, and 8 levels are converted in the second A / D converter 40b. Is converted to a digital signal (111 in binary number).

  On the other hand, as described above, since the analog signal mainly passes through the first filter unit 36a and the second filter unit 36b, respectively, the third filter unit 36c and the fourth filter unit 38d are connected via the third amplifier unit 38c and the fourth amplifier unit 38d. A low level analog signal is input to the third A / D conversion unit 40c and the fourth A / D conversion unit 40d connected to the fourth filter unit 36d. Therefore, each analog signal is converted into a digital signal (001 in binary number) indicating two stages of 8 gradations in the third filter unit 36c and the fourth filter unit 36d.

  Each digital signal converted as described above is output from the first to fourth A / D converters 40a to 40d to the control device 12 (step S4).

  Next, each of the digital signals is input to the control device 12 (step S5), and the control device 12 issues a light emission processing command 100 for each of the parent devices 14 (1) to 14 (4) based on the respective digital signals. Create (step S6).

  In this case, the light emission processing command 100 for the parent device 14 (1) is created based on the digital signal of the first A / D conversion unit 40a, and the light emission processing command 100 for the parent device 14 (2) is the second A / D conversion command. The light emission processing command 100 for the master unit 14 (3) is created based on the digital signal of the D conversion unit 40b, and is created based on the digital signal of the third A / D conversion unit 40c, and the master unit 14 (4). The light emission processing command 100 is generated based on the digital signal of the fourth A / D converter 40d.

  As shown in FIG. 8, each light emission processing command 100 includes start data 102 indicating the start of the command, a plurality of master device control data 104 for controlling the master devices 14 (1) to 14 (4), It consists of end data 106 (synchronization data).

  The base unit control data 104 includes base unit identification data 110 in which base unit number codes 1 to 4 are stored, handset unit identification data 112 in which handset unit number codes 1 to 32 are stored, and each light emitting unit 22 (1). To the slave unit control data 116 for each of the slave units 24 (1) to 24 (32) composed of the light emission information data 114 for causing the.

  The light emission information data 114 stores color data indicating colors that can emit light from the light emitting units 22 (1) to 22 (32). In this case, the control device 12 sets the color data to numbers 0 to 7 corresponding to the above-described gradation levels (1 to 8 steps), and black (0), red (1), green ( 2) Eight colors of yellow (3), blue (4), magenta (5), cyan (6) and white (7) are allocated.

  Here, the black (0) is expressed by turning off the LEDs 58, 60, and 62, the yellow (3) is expressed by turning on the red LED 58 and the green LED 60, and the magenta (5) is expressed by the red LED 58. And the cyan (6) is expressed by lighting the green LED 60 and the blue LED 62, and the white (7) is expressed by lighting each LED 58, 60, 62. . The red (1) is expressed by lighting the red LED 58, the green (2) is expressed by lighting the green LED 60, and the blue (4) is expressed by lighting the blue LED 62. Of course.

  For example, in the case of a digital signal corresponding to the voice “A”, the digital signals output from the first to fourth A / D converters 40a to 40d are gradations of 7, 8, 1, 1 and 1, respectively. Since it is a digital signal indicating a level, the color data stored in the light emission information data 114 is 6 (cyan), 7 (white), 1 (red), and 1 (red).

  In FIG. 9, the light emission processing command 100 for the master unit 14 (1) is representatively shown. The master unit number code 1 is stored in each master unit identification data 110, and the slave unit number code 112 is stored in each slave unit identification data 112. 1 to 8 are stored, and 6 (cyan) indicating color data is stored in each light emission information data 114.

  Next, the control device 12 outputs each light emission processing command 100 created for each parent device 14 (1) to 14 (4) to each of the parent devices 14 (1) to 14 (4) (step S7). .

  Each light emission processing command 100 output from the control device 12 is input to each of the parent device side control units 28 (1) to 28 (4) of each of the parent devices 14 (1) to 14 (4) (step S8). ). Each of the parent device side control units 28 (1) to 28 (4) transfers each of the light emission processing commands 100 to the modulation units 30 (1) to 30 (4), and each of the modulation units 30 (1) to 30 (4). 30 (4) performs modulation processing to superimpose each light emission processing command 100 on a high frequency signal (carrier wave) that can be transmitted as a radio wave. The modulated carrier waves are amplified in the amplifying units 32 (1) to 32 (4) (step S9), and further, each slave unit 24 (1) as a radio wave from the master unit antennas 34 (1) to 34 (4). To (24) (step S10).

  In this case, the radio wave from the master unit antenna 34 (1) is transmitted to each slave unit 24 (1) to 24 (8), and the radio wave from the master unit antenna 34 (2) is sent to each slave unit 24 (1). 9) to 24 (16), and the radio waves from the base unit antenna 34 (3) are transmitted to the respective handset units 24 (17) to 24 (24) and from the base unit antenna 34 (4). The radio wave is transmitted to each of the slave units 24 (25) to 24 (32).

  Specifically, a radio wave indicating 0 to 1 kHz voice is transmitted to each of the slave units 24 (1) to 24 (8), and 1 to 2 kHz voice is transmitted to each of the slave units 24 (9) to 24 (16). A radio wave indicating 2 to 3 kHz sound is transmitted to each of the slave units 24 (17) to 24 (24), and a frequency of 3 kHz or more is transmitted to each of the slave units 24 (25) to 24 (32). Radio waves indicating sound are transmitted.

  The radio waves transmitted from the base unit antennas 34 (1) to 34 (4) are simultaneously received by the slave unit antennas 42 of the slave units 24 (1) to 24 (32). Each electric signal based on the above is amplified by the amplifying unit 44 and further demodulated by the demodulating unit 46 to become digital data (step S11).

  The obtained digital data is simultaneously input to the handset side controller 48 of each handset 24 (1) to 24 (32), and the following processing is performed.

  First, the handset side controller 48 determines whether or not the digital data is the start data 102 of the light emission processing command 100 (step S12). When it determines with it being the start data 102, the said subunit | mobile_unit side control part 48 performs the process of step S11 again, and acquires the following digital data. On the other hand, if it is determined in step S12 that the data is not the start data 102, the handset side controller 48 determines whether or not the digital data is the end data 106 (step S13).

  If it is determined that the digital data is not the end data 106, the handset side control unit 48 determines whether the base unit number codes 1 to 4 in the digital data are base unit number codes stored in the first memory 50. It is determined whether or not (step S14). When the master unit number codes 1 to 4 in the digital data match the stored master unit number code, the slave unit side control unit 48 selects the slave unit number codes 1 to 1 in the digital data. 64 and the own slave unit number code stored in the first memory 50 are compared (step S15), and if they match, the next digital data following the digital data, that is, the light emission information data 114 is obtained, It stores in the work memory 54 (step S16).

  When the digital data does not match the parent device number code stored in the first memory 50 in the process of step S14, or when the digital data does not match the own child device number code in the process of step S15, The subunit | mobile_unit side control part 48 performs the process of step S11 again, and acquires the following digital data.

  When the digital data is the end data 106 in the process of step S13, the slave unit side control unit 48 determines the light emitting units 22 (1) to 22 (1) to based on the light emission information data 114 stored in the work memory 54. 22 (32) is driven to perform a light emission process (step S17).

  By the light emission processing in step S17, as shown in FIG. 10, cyan light is emitted from the light emitting units 22 (1) to 22 (8) of the slave units 24 (1) to 24 (8), and the slave unit 24 (9 ) To 24 (16), white light is emitted from the light emitting units 22 (9) to 22 (16), and from the light emitting units 22 (17) to 22 (24) of the slave units 24 (17) to 24 (24). Emits red light, and red light is emitted from the light emitting units 22 (25) to 22 (32) of the slave units 24 (25) to 24 (32).

  In this case, the light from the light emitting units 22 (1) to 22 (8) is light indicating a sound of 0 to 1 kHz, and the light from the light emitting units 22 (9) to 22 (16) is a sound of 1 to 2 kHz. The light from the light emitting units 22 (17) to 22 (24) is light indicating the sound of 2 to 3 kHz, and the light from the light emitting units 22 (24) to 22 (32) is the sound of 3 kHz or more. It is the light which shows.

  Moreover, the color of the light emitted from each of the light emitting units 22 (1) to 22 (32) corresponds to the sound level, and the black light (0), the red light (1), the green light (2), and the yellow light (3 ), Blue light (4), magenta light (5), cyan light (6) and white light (7) in this order, the sound level increases.

  Therefore, if the audience knows in advance the relationship between light and sound described above, the performer in the event venue inputs the sound of “A” shown in FIG. ) To 24 (32), when each light shown in FIG. 10 is emitted from each of the light emitting units 22 (1) to 22 (32), from the light emission pattern of each light, the audience is 0 to 1 kHz and 1 to It can be understood that the level of 2 kHz audio is high and the level of audio of 2 to 3 kHz and 3 kHz or higher is low.

  That is, the light emission pattern shown in FIG. 10 represents the characteristic diagram of the voiceprint 80 related to the voice “A” shown in FIG. 5 with light.

  In the above processing, if the slave unit number code does not exist in the light emission processing command 100, the slave unit side control unit 48 does not acquire the next light emission information data 114 and of course does not perform the light emission processing.

  A common light emission processing command 100 is simultaneously transmitted from the parent devices 14 (1) to 14 (4) to all the child devices 24 (1) to 24 (32), and the child devices 24 (1) to 24 (24). (32) drives the light emitting units 22 (1) to 22 (32) at the timing when the end data 106 is received, so that the light emitting units 22 (1) to 22 (1) of the slave units 24 (1) to 24 (32) are driven. The light emission timings of 22 (32) can be synchronized, and the light emitting units 22 (1) to 22 (32) can emit light all at once.

  In the first embodiment, the synchronization data for synchronizing the light emission timings of the light emitting units 22 (1) to 22 (32) in the slave units 24 (1) to 24 (32) is the end data 106. The synchronization data is not necessarily limited to the end data 106. For example, the start data 102 or predetermined data other than the start data 102 and the end data 106 can be used as the synchronization data. In this case, the light emitting units 22 (1) to 22 (32) may be caused to emit light after a predetermined time has elapsed since the start data 102 and the predetermined data are received.

  As shown in FIG. 10, the light emission control of the light emission control system 10A described above is performed by the light emitting units 22 (1) to 22 (32) of the slave units 24 (1) to 24 (32) arranged in the audience seats 1 to 32. ) Are emitted in the same color in a horizontal row, but by turning off a part of the slave units arranged in the horizontal row, the above-described gradation level, that is, the sound level for each frequency band Can also be expressed by the number of slave units 24 (1) to 24 (32) that emit light.

  That is, as shown in FIG. 11, by setting only the light emitting unit 22 (8) out of the light emitting units 22 (1) to 22 (8), the sound level of 0 to 1 kHz indicated by cyan is increased. 6 and expressing all the light emitting units 22 (9) to 22 (16) to emit light, thereby expressing that the level of sound of 1 to 2 kHz indicated by white is 7, and the light emitting unit 22 (17 ) To 22 (24), by setting only the light emitting unit 22 (17) to the light emitting state, it expresses that the sound level of 2 to 3 kHz indicated by red is 1, and the light emitting units 22 (25) to 22 (24) 22 (32) expresses that the sound level of 3 kHz or higher indicated by red is 1 by setting only the light emitting unit 22 (25) to the light emitting state.

  In this light emission control, the control device 12 creates a light emission processing command 120 instead of the light emission processing command 100 with respect to step S7 of FIG.

  As shown in FIG. 12, the light emission processing command 120 includes start data 122 indicating the start of the command, a plurality of master device control data 124 for controlling the master devices 14 (1) to 14 (4), and an end. Data 126 (synchronization data).

  The master unit control data 124 includes a master unit identification data 130 in which master unit number codes 1 to 4 are stored, a slave unit identification data 132 in which slave unit number codes 1 to 32 are stored, and the light emitting units 22 ( 1) to 22 (32), each of the child device control data 136 for each of the child devices 24 (1) to 24 (32) including light emission information data 134 for emitting light.

  FIG. 12 representatively shows a light emission processing command 120 for the parent device 14 (1). Each parent device identification data 130 stores a number of 1 indicating a parent device number code, and the child device identification data 132. 1 to 8 indicating the slave unit number codes are stored, and the light emission information data 134 for the slave units 24 (1) to 24 (7) stores 6 numbers for emitting cyan. In the light emission information data 134 for the slave unit 24 (8), a number of 0 for indicating the non-light emission state (black) is stored.

  The above-described light emission processing command 120 is transmitted from the control device 12 to each of the parent devices 14 (1) to 14 (4), and further from each of the parent devices 14 (1) to 14 (4) to each of the child devices 24 (1) to When transmitting to 24 (32) by radio waves, the light emission processing shown in FIG. 11 is performed. Therefore, the light emission pattern by each light from each light emission part 22 (1) -22 (32) has the same effect | action as a graphic equalizer.

  Further, instead of one control device 12, as shown in FIG. 13, a plurality of control devices 12 (1) to 12 (4) send light emission processing commands 100 and 120 to the master units 14 (1) to 14 (4). You may control the light emission of the light emission parts 22 (1) -22 (32) in the subunit | mobile_unit 24 (1) -24 (32) by transmitting each.

  Thus, in the light emission control system 10A according to the first embodiment, in an event venue such as a stadium, studio, hall, etc., the voice of a performer such as a singer is converted into an analog signal by the microphone 16, and the analog signal is The first to fourth filter units 36a to 36d form analog signals for each frequency band, and the first to fourth A / D conversion units 40a to 40d convert the analog signals into digital signals. The control device creates a light emission processing command 100, 120 based on the digital signal, and sends the light emission processing command 100, 120 from each parent device 14 (1) -14 (4) to each child device 24 (1)- 24 (32). Thereby, each said subunit | mobile_unit 24 (1) -24 (32) light-emits each light emission part 22 (1)-22 (32) according to the said light emission process commands 100 and 120. FIG.

  In this case, since the frequency band of the sound is different for each performer, light corresponding to the sound of the performer is emitted from each of the light emitting units 22 (1) to 22 (32). Accordingly, each of the light emitting units 22 (1) to 22 (32) can express a light pattern unique to the performer, and can enhance the production of the event venue.

  In addition, since the light emission processing commands 100 and 120 include the child device identification data 112 and 132 in which the child device number codes 1 to 32 are stored, only the desired light emitting units 22 (1) to 22 (32) are included. It is also possible to control light emission. Therefore, it becomes possible to make each light emission part 22 (1) -22 (32) light-emit by combining the light emission pattern corresponding to the audio | voice mentioned above, and light emission patterns, such as a character and a picture, and further raises the effect of the said event venue. be able to.

  Further, since various lights can be emitted from the light emitting units 22 (1) to 22 (32) according to the frequency band of the sound, the event venue can be further enhanced.

  Furthermore, the luminance of the light emitting units 22 (1) to 22 (32) is changed according to the level of the sound in each frequency band, and various lights are emitted from the light emitting units 22 (1) to 22 (32). Since the light can be emitted, the event venue can be further enhanced.

  Next, a light emission control system 10B according to the second embodiment will be described with reference to FIGS. In addition, about the component same as the light emission control system 10A which concerns on 1st Embodiment, the same referential mark is attached | subjected, the detailed description is abbreviate | omitted, and it is the same below.

  In the light emission control system 10B according to the second embodiment, as shown in FIG. 14, the control device 12 includes a memory 70 for storing a digital signal from the audio / signal conversion device 66. This is different from the light emission control system 10A (see FIG. 2) according to the first embodiment.

  In the light emission control of the light emission control system 10B, the light emission processing commands are sequentially generated in the control device 12 corresponding to the sound sequentially input to the microphone 16 from the outside, and from the parent devices 14 (1) to 14 (4). The light emitting units 22 (1) to 22 (32) are caused to emit light sequentially by sequentially transmitting the light emission processing commands to the slave units 24 (1) to 24 (32).

  Specifically, as shown in FIG. 15, the sound input to the microphone 16 is “a”, “i”, “u”, “e”, “ ".

  Then, the light emission control system 10B sequentially performs light emission control of each of the slave units 24 (1) to 24 (32) in a vertical row for each time period from time t1 to t8 based on each sound at time t1 to t8. To do. For example, for the sound at time t1, the light emission of the light emitting units 22 (1), 22 (9), 22 (17), and 22 (25) is controlled, and for the sound at time t8, the light emitting unit 22 is controlled. (8), 22 (16), 22 (24), 22 (32) light emission is controlled.

  First, at time t1, the light emission control system 10B performs the processes of steps S1 to S4 shown in FIG. Thereby, the sound input to the microphone 16 is output from the sound / signal conversion device 66 as a digital signal having a gradation level shown in FIG.

  Next, after the process of step S5 in FIG. 7, the control device 12 determines whether or not there is a digital signal accumulated in the memory 70 as shown in FIG. 17 (step S20). When there is accumulation, the digital signal is taken out from the memory 70 (step S21), and the digital signal inputted from the audio / signal conversion device 66 is stored in the memory 70 (step S22). In step S20, if there is no digital signal stored in the memory 70, the control device 12 performs the process of step S22.

  Next, the light emission control system 10B executes the processes of steps S6 to S17 shown in FIG. Thereby, based on the audio | voice of time t1, the light emission parts 22 (1), 22 (9), 22 (17), and 22 (25) shown in FIG. 18 light-emit.

  In this case, cyan light is emitted from the light emitting unit 22 (1) and white light is emitted from the light emitting unit 22 (9) based on the gradation levels 6, 7, 1 and 1 (see FIG. 16) at time t1. , Red light is emitted from the light emitting unit 22 (17), and red light is emitted from the light emitting unit 22 (25).

  As described in the first embodiment, the light from the light emitting unit 22 (1) is a light indicating 0 to 1 kHz sound, and the light from the light emitting unit 22 (9) is a sound of 1 to 2 kHz. The light from the light emitting unit 22 (17) is light indicating a sound of 2 to 3 kHz, and the light from the light emitting unit 22 (24) is light indicating a sound of 3 kHz or more.

  Further, the color of each light from the light emitting units 22 (1), 22 (9), 22 (17), 22 (25) corresponds to the sound level, and black light (0), red light (1). The sound level increases in the order of green light (2), yellow light (3), blue light (4), magenta light (5), cyan light (6) and white light (7).

  Therefore, the spectators in the event venue can hear 0 to 1 kHz and 1 to 2 kHz sound from the light emission patterns of each light from the light emitting units 22 (1), 22 (9), 22 (17), and 22 (25). It can be grasped that the level is high and the level of audio of 2 to 3 kHz and 3 kHz or more is low. Furthermore, the light emission pattern by each light from each light emission part 22 (1), 22 (9), 22 (17), 22 (25) shown in FIG. 18 is related to the sound of “A” at time t1 in FIG. The frequency distribution of the voiceprint 80 is expressed by light.

  Based on each sound at time t2 to t8, the light emitting units 22 (2) to 22 (8), 22 (10) to 22 (16), 22 (18) to 22 (24), 22 (26) to 22 (32 In order to emit light), it is needless to say that the processes of steps S1 to S17 and S20 to S22 may be executed based on the light emission process at the time t1 described above.

  In the above-described light emission control system 10B, when the light emission of the light emitting units 22 (1) to 22 (32) is controlled by sound generated from a musical instrument such as a piano based on the score shown in FIG. Instead of the voices "" to "o" (see FIG. 15), the semitone, the A major sound or the scale of FIG. Thereby, the light emitted from the light emitting units 22 (1) to 22 (32) expresses the score.

  Further, when the level of sound in a specific frequency band, that is, the level of the digital signal output from the first to fourth A / D converters 40a to 40d exceeds a predetermined value, the control device 12 sends each master unit 14 A digital signal may be transmitted to (1) to 14 (4) all at once, and the light emitting units 22 (1) to 22 (32) of the slave units 24 (1) to 24 (32) may emit light.

  For example, as shown in FIG. 15, the sound level of “e” at 2 to 3 kHz is higher than the sound levels of “A”, “I”, “U” and “O” at 2 to 3 kHz. Therefore, a digital signal “e” is stored in advance in the memory 70 of the control device 12, and when a predetermined digital signal is output from the third A / D conversion unit 40 c to the control device 12, Corresponding digital signals are output from the control device 12 to the parent devices 14 (1) to 14 (4).

  Further, in the light emission control system 10B, “A”, “I”, “U”, “E” and “O” are stored in the second memory 52 (see FIG. 13) of the slave units 24 (1) to 24 (32). The light emission pattern corresponding to the voice is stored in advance, and the light emission processing commands 100 and 120 (see FIGS. 8, 9 and 12) are transmitted from the parent devices 14 (1) to 14 (4) to each of the child devices 24 (1 ) To 24 (32), the light emitting units 22 (1) to 22 (32) may emit light based on the light emission pattern.

  As described above, in the light emission control system 10B according to the second embodiment, the digital signal converted from the sound by the sound / signal conversion device 66 is sequentially stored in the memory 70 in the control device 12, and is stored in the memory 70. Since the stored digital signals are output in time series, each of the light emitting units 22 (1) to 22 (32) can emit light in synchronization with the sound.

  It should be noted that the light emission control system according to the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted without departing from the gist of the present invention.
