Special table 2001-514432 gazette

  By the way, the device described in Patent Document 1 can be used for a purpose of performing illumination or display of a variable color by arranging a plurality, and the light color of each optical module is instructed through a network. Is possible.

  However, in the configuration described above, there are optical modules that have the same control content when a large number of optical modules are arranged for use in decoration or the like and some pattern is displayed instead of characters and figures. In spite of the high possibility, the control content must be created individually for each power module, and there is a problem that it takes a lot of work time to create the control content.

  The present invention has been made in view of the above reasons, and the purpose of the present invention is to provide each light effect device with the same control content for a plurality of light effect devices having a plurality of light sources having different emission colors. An object of the present invention is to provide a light effect system that makes it possible to share one effect data without creating effect data individually, and to facilitate the creation of effect data.

The invention of claim 1 includes a plurality of light effect devices each having a plurality of light sources having different emission colors and receiving light control data to control the light output of each light source, and the light emission timing of the light sources in each light effect device, and Between the control device and the light effect device, the control device that generates the effect data that designates the light output and transmits the control data including the information and the effect data specifying the light effect device that is the transmission destination to the light effect device. And a light control device that outputs light control data for determining the light output of each light source at each time from the control data to the light performance device. The control device emits light from the light performance device. a light effect device for dimming data is the same at the timing as a group, and the group table registered in association with the plurality of groups belonging light directing device, each group the effect data An effect data setting unit to be set, and a control data output unit that generates control data that includes the effect data for each group set in the effect data setting unit and includes the light effect device registered in the group table. Features.

According to this configuration, since the group table is provided and the light effect devices are associated with a plurality of groups, the effect data is created for each light effect device when the effect data of the plurality of light effect devices is the same. It is only necessary to create one piece of production data for a plurality of light production devices, and production of production data is facilitated. In addition, since which light effect devices are included in the group can be arbitrarily set depending on the contents registered in the group table, various effects can be achieved with the light effect devices. Note that the information for designating the light effect device means an address if the light effect device is individually provided with an address. However, as will be described later, a plurality of pieces connected in cascade even when no address is given to the light effect device. Since it is possible to serially transmit a data group to a single light effect device and extract the necessary data from the data group in each light effect device, the order of the data in the data group in this case It will be included in the information for designating the light production equipment.

According to a second aspect of the present invention, in the first aspect of the present invention, the control data includes the light source of each light effect device when performing light effects in a regular light emission pattern using the plurality of light effect devices. the generated timing and the light output of the light emitting to regularly specified according to the pattern to send the light directing device with regularly controlled according to the pattern, which is controlled by the effect data having the same content in the group table The light production tool is associated with a set of groups.

According to this arrangement, Ru can be a light effect device comprising the same color at the same time when performing an effect of light in a pattern of regular light emission using a plurality and groups. When directing the pattern is a particularly effective to associate the light directing device to a group, it is easy to create working effect data.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the control device and the appliance control device are connected via a network, and the control device is connected to the control data via a network. A display device is provided that receives the control data when the address to be used is not included and performs simulation of the emission color of the light effect device on the screen.

  According to this configuration, the display device provided in the control device that generates the production data can perform the production simulation using the light production device, so that the operation corresponding to the control data can be confirmed without actually operating the light production device. Is possible. Further, even when the control device is operated alone without being connected to the network, the operation of the light effect device can be simulated, so that control data can be created even in a place where there is no environment connected to the network.

  In invention of Claim 4, in invention of Claim 1 thru | or 3, at least 1 of the said light performance implements is connected to the said appliance control apparatus, and the remaining light production implements are connected by light production implements, Connected to the control line that serially transmits the dimming data output from the fixture control device, fetches a specified number of dimming data from the head, and uses it to control the light source and transfers the remaining dimming data to other lighting effects fixtures And a data transmission / reception unit.

  According to this configuration, when connecting a plurality of light effect instruments to the instrument control device, it becomes a cascade (cascade), so that the light effect instruments can be easily connected and expanded, and the instrument control device Since each fixture control device takes in a specified number of dimming data from the beginning of the dimming data output from the camera, and transfers the remaining dimming data to other lighting fixtures, each lighting fixture has an address setting. Is not necessary, and it is only necessary to determine a rule for acquiring dimming data (the number of dimming data acquired from the top), and the construction work of the light effect device is easy.

  According to a fifth aspect of the present invention, in any of the first to fourth aspects of the present invention, a light emitting diode of three colors of RGB is provided as a light source in the light effect device.

  According to this configuration, since three colors can be mixed using a light source close to a point light source, the color mixing property is good and the light color can be changed over a wide range. In addition, since the light emitting diode has a long life, it can be used for a long period of time, resulting in less generation of waste and saving resources and reducing disposal costs.

According to the configuration of the present invention, since the group table is provided and the light effect device is associated with the plurality of groups, when the effect data of the plurality of light effect devices is the same, the effect data for each light effect device. There is an advantage that it is only necessary to create one piece of production data for a plurality of light production devices without creating the production data. In addition, since which light effect devices are included in the group can be arbitrarily set according to the contents registered in the group table, there is an advantage that various effects can be performed with the light effect devices.

  In the present embodiment, when a plurality of light effect devices including light emitting diodes of three colors of RGB as light sources are used and light effects are performed by controlling the light emission timing and light output of each light effect device, respectively. Will be described as an example. This type of effect is used, for example, for a decorative display. Since the light production equipment uses a light emitting diode as a light source, it has a long life, saving resources and reducing the disposal cost. In addition, by using a light-emitting diode as a light source, the light-emitting area per color is small, so that it is possible to extract mixed-color light with good color mixing properties. Furthermore, since three colors are mixed, the light color can be changed over a wide range. become. If a light production device is configured by using three-color light emitting diodes housed in one package and arranging a plurality of packages, the light emitting area can be increased while ensuring color mixing.

  In this embodiment, as shown in FIG. 1, the control apparatus 1 which produces | generates the production data which controls the light emission timing and light output of the light source in each light production instrument 3 is provided, and the control apparatus 1 transmits with production data. Control data including information for designating the previous lighting device is transmitted to a general-purpose network NT such as Ethernet (registered trademark). The control data transmitted through the network NT is received by the fixture control device 2, and the fixture control device 2 designates the dimming data for controlling the light output of each light source in each light effect fixture 3 by the calculation data. To output. In other words, the appliance control device 2 generates dimming data that determines the light output of each light source at each time in the light effect appliance 3 using the control data transmitted from the control device 1, and the transmission specified by the control data It has a function of transferring dimming data to the previous light effect device 3. In addition, in the appliance control apparatus 2, if control data is received once from the control apparatus 1, until the next control data is received, the same light control data will be repeatedly given to the light production instrument 3 based on the same control data.

  The fixture control device 2 outputs dimming data in a plurality of systems, and each system can be connected to a plurality of light effect devices 3, but in each system, only one light effect device 3 controls each. It is directly connected to the fixture control apparatus 2 via the line L1, and the remaining light production fixtures 3 of each system are connected to other light production fixtures 3 via the control line L1. In short, in a system in which a plurality of light production tools 3 are connected, the first light production device 3 is connected to the device control device 2 and the second light production device 3 is connected to the first light production device 3. As shown in the figure, the light effect device 3 is cascaded. Thus, connection construction becomes easy by connecting the light effect appliances 3 in cascade. Moreover, when adding the light effect device 3, it is only necessary to add the light effect device 3 to be added to the terminal light effect device 3 and connect the light effect device 3.

  As shown in FIGS. 2B and 2C, the dimming data transmitted through each system is dimming data Dmi (i is a natural number of 512 or less) that specifies the light output of the light source in each light effect device 3. The control signal L1 is sequentially connected and a synchronization start signal ST is added to the head, and the control line L1 is serially transmitted. Here, a signal of the RS-485 specification is used as the signal to the light effect device 3, but the format is the same as that of the dimming control signal described later. The light effect device 3 includes a data transmission / reception unit that takes in three pieces (specified number) from the light control data next to the start signal ST and transfers the remaining light control data to the other light effect devices 3. In other words, since the light effect device 3 of the present embodiment is provided with light emitting diodes of three colors, the three light control data for instructing the light output of each of the three light emitting colors are fetched and the remaining light control diodes are fetched. The optical data is transferred to the light production instrument 3 (which is far from the instrument control device 2). Assuming that 30 dimming data are connected and output from the fixture control device 2 to one system, the first light production fixture 3 closest to the fixture control device 2 in this system has 30 units. Although dimming data is input, 27 dimming data are input to the second light effector 3, and 24 dimming data are input to the third light effector 3. In this way, the number of dimming data decreases by three each time the light effect device 3 is passed. In other words, the light effect device 3 performs an operation of taking out three pieces of dimming data after the start signal ST from the head, and sending the rest to the other light effect devices 3 together with the start signal. The fixture 3 uses the order of the dimming data as information for specifying the destination of the dimming data without setting an address. Each light effect device 3 maintains the light output instructed by the current dimming data until the next dimming data is received.

  By the way, the appliance control apparatus 2 includes a regenerator 21 that receives control data from the network NT and reproduces the production data. The regenerator 21 uses a DMX512 protocol that is generally used in dimming control. The dimming control signal output from the regenerator 21 is input to the power supply unit 22. In the instrument control apparatus 2, a maximum of ten regenerators 21 can be provided. Further, the power supply unit 22 is provided for each system of the light effect device 3, and a plurality of power supply units 22 can be connected to one regenerator 21. In the illustrated example, the power supply unit 22 is multidrop connected to the regenerator 21. Since the regenerator 21 is connected to the network NT, an IP address is set for the regenerator 21. As described above, up to ten regenerators 21 can be provided in the instrument control device 2, and one instrument control device 2 uses a maximum of 10 IP addresses to distinguish each regenerator 21. .

  As shown in FIG. 2A, the dimming control signal output from each regenerator 21 sequentially connects 512 dimming data Dmi (i is a natural number equal to or smaller than 512), and starts with a start signal for synchronization. In this format, ST is added, and the data format of the dimming control signal is the same as the data format of the signal output from the power supply unit 22. However, the data group of dimming data output from the power supply unit 22 is an arbitrary number of 512 or less with respect to one start signal ST, but the data group of dimming data output from the regenerator 21 is 1. The number is always 512 for each start signal ST. The start signal ST is generated at a constant cycle, and 512 dimming data are output from the regenerator 21 at a constant cycle.

  On the other hand, as shown in FIG. 1, the power supply unit 22 includes a data processing unit 22 a and an extraction address setting unit 22 b that extract the dimming data to be transmitted to the light effect device 2 from the dimming data transmitted from the regenerator 21. Is provided. The extraction address setting unit 22b can set an appropriate value from 1 to 512, and the data processing unit 22a uses the extraction address setting unit 22b in the order of the dimming data among the dimming data included in the dimming control signal. Only dimming data after the set order is transferred to the light effect device 3. In short, the dimming control signal can be regarded as dimming data having addresses 1 to 512 arranged in the order of addresses following the start signal ST, and the data processing unit 22a is set in the extraction address setting unit 22b. It can be said that it has a function of extracting dimming data having addresses after the address.

  For example, FIG. 2B shows an example in which the address is set to “101” in the extraction address setting unit 22b, and only the 101st and subsequent dimming data of the dimming control signal shown in FIG. Are extracted by the data processing unit 22a. That is, among the light control data included in the light control signal, the 101st and subsequent light control data is transferred to the light effect device 3. Further, as described above, since the light effect device 3 takes three pieces of dimming data from the top and delivers the rest to the other light effect devices 3, the first light effect device 3 closest to the power supply unit 22 is 101. The 103rd to 103rd dimming data is fetched, and the 104th and subsequent dimming data are delivered to the second light effect device 3 as shown in FIG. The light effect device 3 does not require an answerback when transferring the light control data to the other light effect device 3, and the light effect at the latter stage (that is, the side far from the power supply unit 22) to which the light control data is to be sent. The instrument 3 may not be connected. In other words, the number of dimming data transmitted from the power supply unit 22 may be larger than the number of light effect devices 3 connected to the power supply unit 22.

  Incidentally, as described above, the control device 1 generates effect data for controlling the light emission timing and light output of the light source in the light effect device 3, and the effect data designates the light effect device 3 that is the transmission destination. Together with the information to be transmitted as control data to the appliance control device 2. As is apparent from the above description, the information specifying the light effect device 3 includes the IP address of the regenerator 21, the address set by the extraction address setting unit 22 b of the power supply unit 22, and the connection of each light effect device 3. It is determined by three types of information. Hereinafter, these three types of information are collectively referred to as a destination address. That is, if the transmission destination address is designated, the light effect device 3 to which the effect data is to be transmitted is determined. Here, among the information included in the effect data, the dimming data for determining the light output of the light effect device 3 is transmitted to the light effect device 3, but the timing of light emission is determined by the regenerator 21. Only the light 21 is received, and the dimming data transmission timing in the dimming control signal is determined so that the light source of the light effect device 3 emits light at the timing instructed by the regenerator 21.

  In the present embodiment, the light effect device 3 having the same dimming data at the timing when the light effect device 3 emits light is associated with the group. That is, the control device 1 includes a group table 11 registered in association with the group to which the transmission destination address of the light effect device 3 belongs. If a group is specified, the control device 1 is collated with the group registered in the group table 11. The destination address belonging to the group is extracted. On the other hand, the effect data is set for each group in the effect data setting unit 12, and the effect data for each group set in the effect data setting unit 12 is input to the control data output unit 13. The control data output unit 13 has a function of associating the production data with each transmission destination address by collating the group of the production data with the group table 11. In other words, the control data output unit 13 generates control data that includes the production data for each group set by the production data setting unit 12 and uses the light production device 3 registered in the group table 11 as a transmission destination. The control data generated by the control data output unit 13 includes a transmission destination address and production data for each light production device 3, and is sent to the network NT through the communication control unit 14 that connects to the network NT.

  As described above, by providing the group table 11 and associating the destination address with the group, when the production data for the plurality of light production devices 3 is the same, production data is created for each light production device 3 It is possible to control a plurality of light effect devices 3 only by creating one effect data. For example, when the light effect device 3 is regularly arranged as shown in FIG. 3 and the light output of the light source of the light effect device 3 is regularly controlled, light emission for each transmission destination address is performed. Since the timing and the optical output also change regularly, the destination address is designated by a regular pattern. Therefore, it becomes possible to create the group table 11 so that the light production device 3 specified by the regular pattern is a set of groups G1 to G7. As a result, the production data is grouped into the groups G1 to G7. Since it is only necessary to create the production data, the amount of work required to produce the production data can be greatly reduced as compared with the case where production data is created for each light production device 3.

  The effect data setting unit 12 includes a parameter setting register 12a that stores parameters of the light emission color and the light emission pattern of the light effect device 3, and an effect data calculation unit 12b that converts the parameters stored in the parameter setting register 12a into effect data. Prepare. The parameters are the type of pattern expressed by the light effect device 3, the specified color that is the main light emission color of the light effect device 3, the background color that is the light emission color that follows the specified color, and one cycle for one pattern. It means a certain cycle time, a fade time that is a time during a change when the light quantity or light color is continuously changed, and the like. A plurality of types of patterns are registered in advance, and a user can create a new pattern as necessary. Here, the pattern is, for example, a pattern in which one light effect device 3 is continuously lit in a specified color, a pattern in which the light color is cyclically changed over time, or a time from the specified color to the background color. It means a pattern that changes with the passage of time, a pattern that blinks the light source with the specified color, a pattern that changes the light color cyclically with the passage of time while blinking the light source, and the parameter settings change according to the specified pattern . The parameters are set in the parameter setting register 12a by input means such as a keyboard or a fader (not shown).

  As described above, a parameter as a pattern is set in the parameter setting register 12a. However, in order to control the light effect device 3, it is necessary to instruct a light emission color and a light emission timing. Therefore, an effect data calculation unit 12b is provided to convert the parameters into effect data. That is, the effect data calculation unit 12b generates effect data including the timing at which each light effect instrument 3 emits light and the light emission color at the time of light emission, from the parameters set in the parameter setting register 12b. Of the effect data, the luminescent color is specified by the light amount level of each color of RGB. For example, if the light intensity levels of RGB colors that determine the luminescent color are Ri, Gi, Bi, the luminescent color GRi in the effect data is represented by a triplet of GRi = (Ri, Gi, Bi). In other words, the effect data calculation unit 12b has a function of converting the parameters relating to the emission color among the parameters received from the parameter setting register 12a to the light amount levels of the respective RGB colors. Moreover, the parameters relating to time may be used as they are in the production data.

  The control device 1 is provided with a display device 15, and an effect expressed by the light effect device 3 can be displayed on the display device 15 for simulation. The control device 1 can be realized by executing an appropriate program on a normal personal computer. In this case, a display device can be used as the display device 15. In order to perform the simulation in the display device 15, it is necessary to provide the display device 15 with information included in the control data transmitted to the device control device 2, and therefore the control data output unit 13 performs the simulation of the emission color of the light effect device 3. If so, the control data is transferred to the display device 15. Whether the control data generated by the control data output unit 13 is transferred to the appliance control device 2 or the display device 15 is determined by the IP address included in the control data. That is, the maximum number of IP addresses used for the appliance control device 2 to connect to the network NT is 10 as described above, and if none of the 10 IP addresses used by the appliance control device 2 is included, the control device Since control data cannot be transmitted from 1 to the appliance control device 2, in this case, the control data is transferred to the display device 15, and the lighting device 3 is lit in the display device 15 for simulation. . If the display device 15 is switched to a state in which the simulation is performed when the IP address of the control device 1 is specified, the simulation is performed only by specifying the IP address, or the control for controlling the light effect device 3 is performed. It is preferable to switch whether data is transferred to the instrument control device 2.

  As described above, the control device 1 can simulate the state of the effect by the light effect device 3, so that various effects by the parameters set in the parameter setting register 12a before the light effect device 3 is actually operated. Can be visually confirmed in advance, and parameter setting work is facilitated. Such parameter setting work can be performed without connecting the control device 1 to the network NT, and it is possible to create control data even in a place where there is no environment connected to the network NT.

  In the above-described embodiment, the light emitting diode is exemplified as the light source. However, it does not prevent the use of another light source such as an organic EL as the light source of the present embodiment. In addition, although the technology has been described in which the light production device 3 acquires the dimming data according to the specified rule without having the address in the light production device 3, it is also possible to individually set the address in the light production device 3. .
