  However, the idea of the music-linked lighting control described in the above-mentioned literature substantially associates the percussion part rhythm (musical notes) in the music data with the lighting pattern on a one-to-one basis. Therefore, the lighting pattern changes without busy according to the rhythm of the song, but the method of switching the lighting pattern uniformly on the basis of the rhythm in this way diminishes the unique characteristics of each song. , Slow-tempo moody songs, songs with large tone changes, etc.), it is considered that it cannot effectively raise the viewer's mood. Also, when you want to change the lighting pattern at an appropriate timing according to the atmosphere of the song when you change the song at a general home or small store, create a lighting pattern switching point with a high degree of freedom according to the progress of the song It would be more desirable to be able to edit.

  In view of the above situation, an object of the present invention is to provide an illumination control device that can create and edit illumination pattern data for each song with a high degree of freedom and flexibility at low cost.

  One aspect of the present invention made to achieve the above object is classified by one or more lighting connection terminals, switching points set in association with the elapsed playback time of the music file, and each switching point. A storage means for storing an illumination pattern designating an illumination connection terminal to which a voltage should be applied for each time zone, and a switching point corresponding to the music file and an illumination pattern designated for each time zone are read from the storage means, and the elapsed playback time The illumination control device includes a control unit that sequentially applies a voltage to the illumination connection terminal based on an illumination pattern corresponding to each time zone as it progresses. Since the switching point can be set in association with the elapsed playback time of the music, when the user changes the music, the user can change the music at any time (for example, the end of the bar of the music, the boundary between A melody and B melody). The lighting pattern can be set to change at any timing at which the music tone changes (such as between the transposition timing and between the rest and the note), and the flexibility and flexibility in creating and editing the illumination pattern data is improved. In addition, since only the switching point is stored in the lighting control device without storing the music file itself, for example, the device can be constructed using an inexpensive general-purpose programmable logic controller (PLC), and the manufacturing cost can be reduced. . Also, when you want to increase the number of songs, you can cope with the expansion of inexpensive external storage media.

  In one aspect, the illumination control device can set the switching point according to the trigger generation timing by the trigger generation means. It is possible to input the music tone change timing to the storage means based on user judgment and to input the music tone change timing to the storage means via a personal computer or the like using an appropriate music tone change detection software.

  In one aspect, the lighting control device further stores an identifier assigned to each music file by the storage means, and the control means plays a music file to be played back to the music playback device according to the identifier. Can be instructed to play. With such a configuration, even when there are a plurality of songs on the storage medium of the song playback device, the songs can be freely selected instead of being played back in the order of the recorded songs.

  In one aspect, the lighting control device stores a combination of an identifier assigned to each music file, a switching point, and a lighting pattern as a program identifier, and the control unit is assigned a designated program identifier. The combination can be read out. With such a configuration, the music and the corresponding lighting effect are linked, and in accordance with the identifier of the music file included in the combination, the music playback device is instructed to play the music file to be played, and corresponds to the music. A voltage can be applied at a predetermined timing based on the switching point and the illumination pattern.

  In one aspect, the lighting control device stores the permutation of program identifiers as a program identifier, and the control unit sequentially performs combination processing according to the permutation of program identifiers included in the designated program identifier. Is something that can be done. With such a configuration, it is possible to freely change the song order and the song change by rearranging, deleting, and adding the program identifier, and the lighting effect is also changed according to the change of the program identifier. It becomes easy.

  In one aspect, the illumination control device includes an output terminal for instructing the music playback device from the control means to start playback of the music file. With such a configuration, the next music is not reproduced without an instruction from the control means, so that the scale of the lighting effect does not depend on the scale of the music file, and only the lighting is maintained for a certain period of time after the music playback is finished. It will be possible to produce a reverberation.

  In the lighting control apparatus, in one aspect, the trigger is a digital signal. With such a configuration, a switching point can be set directly for a general-purpose PLC.

  In one aspect, the illumination control device is such that the trigger generating means is a push button (contact button). With such a configuration, the user can set the switching point at an arbitrary timing according to the atmosphere of the song, and the operability becomes more intuitive and simple.

  In one aspect, the illumination control device is such that the trigger generating means is a photoelectric sensor, a thermal sensor, or a sound sensor. With such a configuration, a person with a disability who cannot easily press a button can easily set a switching point using a sensor.

  In one aspect, the lighting control device includes a clock built in the control means, and can execute the program program designated at a designated date and time, timing or period. With such a configuration, it is possible to operate music-linked lighting only at night and to change the program according to the season, so that it is possible to set a production program that does not get tired of the viewer, and wasteful power during the daytime when there is no lighting effect. Consumption disappears. It can also be used for crime prevention purposes by changing only the lighting without playing music at night.

  In one aspect, the lighting control device further includes a lighting device connected to the lighting connection terminal.

  Another aspect of the present invention made to achieve the above object is a music comprising the above lighting control device and a music playback device directly or indirectly connected to an input terminal or an output terminal of the lighting control device. This is an interlocking lighting control device.

Embodiments for carrying out the present invention will be described below with reference to the drawings.
(First embodiment)
The typical lighting control device shown in FIG. 1 has a storage means for storing predetermined information, a control means for reading out and processing the information, and outputting the information to the outside of the apparatus. A user interface (UI) section for sending the instruction, an external output terminal for outputting a predetermined output from the control means to the external unit, and a timer connected to the control means for measuring the elapsed playback time.

  The storage means includes one or more program component programs, one or more programs included in one program program, a music file identifier included in one program, and one or more switching points. Further, hierarchical data of one or more illumination patterns is stored. In the example of FIG. 2, two programs are included in the program component program assigned the program identifier # 11. The program identifier # 60 is assigned to the program 1, and the program identifier # 8 is allocated to the program 2, and the program is configured to proceed in this order. Here, the music file number # 5 is assigned to the program to which the program identifier # 60 is attached, and three types of music switching point information, lighting pattern information, and push button identifiers corresponding to the music file number # 5 are assigned. As a set, n pieces are numbered and included in the order of progression of the music (pattern numbers 1 to n). On the other hand, music program file number # 1 is designated as performance identifier # 8, and music file number # 1 corresponds to it. The switching point information, lighting pattern information, and push button identifiers of the music to be played are included in a set of three types, numbered in order of the progress of the music (pattern numbers 1 to m). Here, n and m are positive integers of 1 or more independent of each other. In the present embodiment, all hierarchical data can be set from a UI unit described later.

  The music file identifier is associated with a music file on an external storage medium that can be played back by a music playback device connected to the lighting control device via an output terminal, and is a number that designates a music file to be played back.

  The switching point information is an enumeration (number sequence) of times (timing) for switching the illumination pattern set in association with the elapsed playback time of the music file on the time axis where the playback start time of the music file is 0 seconds. Here, it should be noted that the switching point divides the time axis based on the reproduction start time of each music file, and does not divide the music file itself. In this embodiment, the timing is set in increments of 0.1 seconds, but is not particularly limited.

  The elapsed music file playback time is the elapsed time from the start of playback of the music file. Accordingly, the elapsed playback time of the music is a concept different from the required playback time of the music itself, and may be made longer than the required playback time of the music according to the music by the time zone editing function of the UI unit described later. It can be made shorter or equal.

  The elapsed playback time of the music file is divided into n time zones (time windows) by n switching points, and music composition classification information and illumination pattern information are assigned to each time zone.

  The illumination pattern information is specified by a unique identifier (number) assigned to each of one or more illumination connection terminals to which a voltage is to be applied. Thus, a voltage is applied to the illumination connection terminal designated by the identifier for each time zone.

  The UI unit includes a touch panel input unit provided on the control box board surface for constructing hierarchical data for the storage unit, specifying a program identifier to be executed by the control unit, and one or more in the music file And a push button for inputting the switching point intuitively and simply to the storage means.

  The touch panel input means has a time zone editing function. With the time zone editing function, once the switching point and time zone are set with a push button, the specific time zone can be re-delimited afterwards, the position (timing) of the switching point can be finely adjusted, It is a function that adds a new switching point and time zone at the timing. With this function, for example, as shown in FIG. 3, when there is a silent time zone or a time zone in which the volume is extremely small in the intro time zone immediately after the music file playback starts, the blank time zone is only after that time zone. As shown in FIG. 4, it is possible to add a time zone in which only lighting is activated after the reproduction of the music file is completed, as shown in FIG. In the example of FIGS. 3 and 4, the switching point and the time zone are increased by the same number by the time zone editing function.

  The touch panel input means has a test reproduction function. The test reproduction function is a function for confirming whether or not the music piece and the illumination are successfully linked (synchronized) by causing the control means to experimentally execute the program identifier designated by the touch panel input means. When the test playback function is executed, the touch panel is configured to display the contents of the combination setting of the currently playing program for confirming the progress of the program by the user. Further, the time zone editing function cannot be executed when the test playback function is executed.

  The push button is a switch with an indicator lamp that is installed on the control box board surface in association with a general music composition such as intro, A melody, B melody, rust, interlude, C melody, outro and others. When a music file is played, the playback elapsed time is counted from 0, and when the push button is pressed, the press timing is stored in the storage means as a switching point, and the pressed push button identifier (push button identifier) is The configuration classification information is configured to be given to the time zone immediately before the switching point. In this embodiment, since a general-purpose PLC is adopted as the storage means and the control means, a digital signal is adopted as a trigger.

  The control means can read from the storage means hierarchical data constructed in the storage means by input to the UI unit. The timing at which the control means reads the data is as follows: (1) The hierarchical structure data may be read collectively when the program identifier is changed, or (2) the program identifier of the next program is read as the program progresses. The data may be read sequentially at the timing, or (3) when the program identifier setting is changed, all program identifiers included in the program specified by the identifier are read and combination setting data is read. Although it is good, it is (3) when using PLC.

  The control means can also provide a predetermined output to the external unit through the external output terminal. In the present embodiment, the music playback device is instructed to start playback of the music file corresponding to the specified music file identifier via the output terminal, and 1 or based on the illumination pattern information read from the storage means A voltage signal is applied to two or more specific illumination connection terminals.

  The control means further incorporates a clock, reads the performance of the specified program identifier from the storage means at the date, time, or time zone specified by the touch panel input means, and plays the music specified by the music file identifier. In addition to instructing the apparatus, a voltage is sequentially applied to the illumination connection terminals based on the illumination pattern as the music plays. When starting with the date and time set, the display on the touch panel is not switched in the state when the date and time is set, but is configured so that the user can switch arbitrarily. However, the time zone editing function cannot be executed when the program is executed.

  The music playback device connected to the output terminal is not particularly limited as long as it has a specification that can specify the playback start timing of the music file, that is, an external contact input terminal. As an external storage medium, a CD, CD-R, USB memory, or the like can be used as appropriate in accordance with the specifications of the music playback device. In this embodiment, an MP3 player manufactured by STEC is employed as the music playback device, and an SD card is employed as the external storage medium. One music file includes one or more music, and in this embodiment, music to be linked with lighting is stored as music files with names and extensions of 001.mp3 to 007.mp3. Has been. For music file creation and editing, music editing software that is commercially available or allowed to be used free of charge on the Internet can be used.

  As the lighting device connected to the lighting connection terminal, any lighting device can be used as long as one or two or more lighting units are turned on, blinked, or pattern blinked by voltage application. As the illumination unit, for example, LED elements; LCD modules; filament tubes; Nixie tubes, mercury lamps, fluorescent lamps and other discharge lamps can be used in appropriate combination. Even if the lighting unit is in a form in which the lighting units are individually independent or is generally referred to as light-up lighting arranged and formed as a collection of lighting units in a matrix, It may be formed as an aggregate and turn on individual lighting units by addressing. In addition, the lighting device has a control unit that is independent of the lighting unit and the lighting control device of the present invention, and the setting or voltage application to the control unit allows two or more elements or a group of elements to be turned on or off. It may indicate a blinking pattern or a light emission color change.

  The control means, storage means, and timer mentioned above are formally separated as functional components, but one device (for example, PLC CPU) may be responsible for all or part of them. Good.

The operation of the lighting control device based on the above configuration will be described.
The hierarchical structure data can be constructed by the switching point information setting flow shown in FIG. 5 and the illumination pattern setting flow shown in FIG. 6, and the execution of the program based on the hierarchical structure data proceeds according to FIG. The layout of the touch panel input means will be described on the assumption of the configuration of FIG.
(Switching point information setting flow)
First, when a music identifier (for example, music 5) is designated on the touch panel (S1), the timer of the control means is reset (S2), and the elapsed playback time becomes 0 seconds. At the same time, a synchronization signal is input to the external music playback device by relay output (S3), and playback of the music (005.mp3) corresponding to the specified music identifier is started. With this as a trigger, the timer count of the elapsed playback time starts (S4). Next, the control means monitors the pressing of the pushbutton switch on the control box board surface (S5), the time of the timer (S6) at the time of pressing, the type of the pressed button (S7), and the pressing of the button from the start of music playback Get information about the number of times. Here, the number n of times of pressing corresponds to the pattern number n, and the pattern number n is assigned to the time period from the (n-1) th pressing to the nth pressing. In the pattern number n, information on the push button identifier corresponding to the music composition classification information in the time zone immediately before the timer time is recorded together with the timer time corresponding to the acquired n-th switching point. When the recorded information has been displayed on the touch panel (S9), the pattern number is incremented by 1 (S10). During the timer count, whether or not the enter button on the touch panel is pressed is constantly monitored (S11), and the next press of the push button switch is continuously monitored unless the enter button is pressed (S5). When it is determined that the decision button has been pressed, the switching point setting corresponding to the pattern number is completed (S20). It should be noted that the switching point information set by the above flow can be finely corrected at a later time by the time zone editing function of the touch panel described above.
(Lighting pattern setting flow)
In setting the illumination pattern (S31), the touch panel input means receives the input of the pattern number (S32) and simultaneously monitors the pressing of the main screen button (S39). When there is an input of a pattern number, reference is made to data relating to the illumination terminal number to be applied with voltage stored in the pattern number (S33), and on / off change of the illumination terminal number button is accepted (S34) and at the same time the main screen The pressing of the button is also monitored (S38). When there is an on / off change, the change is reflected in the data of the pattern number (S35), and the voltage application / cutoff to the illumination connection terminal having the change is switched (S36). Thereafter, when the selection copy button to the next pattern is pressed, the pattern number is incremented by 1 (S41), and the ON / OFF information of the illumination terminal number button stored in the pattern number before the increment of 1 is transferred there. Above (S42), the pattern number increased by 1 is referred to (S33). When the main screen button is pressed (S38) after the on / off change or without changing, the screen transitions to a screen (S32, S39) that accepts the next pattern number input or the main screen button press, and again the main screen If the button is pressed (S39), the combination setting is completed (S40).
(Program execution flow)
In response to designation of the program identifier on the touch panel by the user (S51), the program identifier accommodated in program identifier program 1 is read (S52), and the music identifier in the program identifier is read (S53). Then, the timer of the control means is reset (S54), and the playback elapsed time becomes 0 seconds. At the same time, a synchronization signal is input to the external music playback apparatus by relay output (S55), and playback of the music corresponding to the specified music identifier is started. With this as a trigger, the timer count of the elapsed playback time starts (S56). The first pattern number is immediately referred from the storage means (S57), and the illumination pattern corresponding to the pattern number is output (S58). At the same time, the first switching point information is read (S59). At this time, the touch panel displays the first pattern number in a blinking manner, while the pushbutton indicator of the pushbutton identifier recorded in the pattern number 1 is turned on. Monitoring is continued until the timer count reaches the switching point (S60). When the arrival is confirmed, it is confirmed whether or not the next pattern number exists (S61). If it exists, the pattern number is incremented by one (S62), and the pattern number is referred to (S57). On the other hand, if the next pattern number does not exist, execution of the program 1 is immediately terminated (S63). When the program 1 ends, it is then determined whether or not there is a next program (program 2) in the program designated by the same program identifier. If there is a program, the program identifier is read (S52). The subsequent procedure is the same.

(Second Embodiment)
The difference of this embodiment from the second embodiment is that, as shown in FIG. 9, an input terminal is provided for inputting information to the storage means and sending a predetermined instruction to the control means.

  The input terminal is connected to a general-purpose computer via a serial communication cable, and can transmit an electric signal (digital signal) from the general-purpose computer to the PLC. General-purpose computers have software that implements an algorithm for reading out tune changes. The software can detect a music tone change point as switching point information by importing a music file and analyzing the data. The general purpose computer is configured to convert the detected switching point information into an electrical signal. As an algorithm for reading the tune change, those disclosed in JP-A-5-273976, JP-A-2004-184769, JP-A-2004-233965, etc. can be employed.

  In the present embodiment, the switching point creation work using the push button by the user is automated by the computer, and the time zone editing work for each music piece is simplified.

(Third embodiment)
The difference between this embodiment and the second embodiment is that, as shown in FIG. 10, the general-purpose computer has a timer, and the general-purpose computer is different from the music playback device and the control means in the lighting control device. The point that the start timing of music and lighting is directly instructed, and the input / output means are integrated by a LAN cable.

  In the present embodiment, the lighting control device is reduced in size by eliminating input means such as a touch panel, and there is an advantage that a general-purpose computer can perform one-stop from creating and editing a performance to executing it.

  As mentioned above, although the Example of this invention was described, this invention is not limited to these embodiment, In the range which does not deviate from the summary, it can implement with a various form further. For example, in the first embodiment, the touch panel input means is fixed on the control box board surface, but it may be configured as a separate box, and may be carried to a place separated by an extension cord, or may be detachable. You can also In the first embodiment, a push button is used as the trigger generating means, but a photoelectric sensor, a thermal sensor, or a sound sensor can be used instead.
